     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , a connector system  110  is configured to transfer both electrical power and signals (e.g., control and data signals) between a power source  101  and a controller  102  and a module  103  located remotely thereto. The power source  101  and/or the controller  102  may be positioned in an enclosure  104  to which the connector system  110  is coupled. The connector system generally includes a receptacle assembly  120  (e.g., receiver, base, female assembly, female connector, etc.) and a plug assembly  150  (e.g., plug connector, male assembly, male connector, etc.) mechanically and electrically connected to a cable  160 . The connector system  110  may, for example, be used in a passenger vehicle  100 , or other application. 
     Referring to  FIG. 2 , the receptacle assembly  120  provides a combined power/data connection point  222  at which the receptacle assembly  120  receives the plug assembly  150  to provide combined power and data connections (i.e., by providing power transfer and data transfer via separate electrical connections). The receptacle assembly  120  may additionally include one or more or data-only connection points  224  at which the receptacle assembly  120  receives other connectors to provide a data-only connection (i.e., by providing data transfer via an electrical connection, which may include incidental power transfer at low levels). The connector system  110  additionally provides electromagnetic shielding to prevent interference that might otherwise occur due to the relatively high electrical output of the power connection (e.g., 48V or 60V at approximately 15 amps), close proximity of other electronic components to the connections formed between the receptacle assembly  120  and the plug assembly  150 , and a high prevalence of interference sources in the vehicle  100  (e.g., electrical powertrain, etc.). The connector system  110  may additionally be configured to provide a sealed connection between the receptacle assembly  120  and the plug assembly  150 , as well as within the receptacle assembly  120  itself, thereby allowing the connector system  110  to be used in locations of the vehicle  100  that are unenclosed and exposed to external environmental conditions (e.g., rain, snow, dust, etc.). According to alternative embodiments, the receptacle assembly  120  may be configured with different numbers of combined power/data connection points  222  and data-only connection points  224 . For example, as shown in  FIG. 16 , a receptacle assembly  1620  includes four combined power/data connection points  222  and four data-only connection points  224 . 
     Referring to  FIGS. 1-4 , the cable  160  is fixedly coupled to the plug assembly  150 , so as to be able to transfer both power and data to the module  103 . For data transfer, the cable  160  may be configured similar to a coaxial cable, as described in further detail below, but may instead be configured similar to other types of shielded data transfer cables (e.g., shielded twisted pair, etc.). 
     As shown in the cross-sectional view in  FIG. 5 , the cable  160  includes a central data conductor  561 , an insulator layer  562 , and a shielding layer  563 , and may additionally include a protective layer  564  (e.g., jacket or additional insulating layer). The cable  160  is also configured to transfer power, and includes appropriate power conductors  568 , which may, for example, be round copper cables. The power conductors  568  may be power and ground conductors. 
     The plug assembly  150  is coupled to the cable  160  and is configured to be received by (e.g., mate with) the receptacle assembly  120 , so as to transfer both power and data therewith. Referring to  FIGS. 6-7 , the plug assembly  150  includes a radially inner portion  650   a  (e.g., inner or data connector portion) for data transfer and a radially outer portion  650   b  (e.g., outer or power connector portion) for power transfer. By arranging various data transfer components radially in between the various power transfer components, efficient packaging of combined power and data transfer connector system is achieved.  FIGS. 14-15  are cross-sectional views of the plug assembly  150  and the receptacle assembly  120 , which illustrate the spatial relationships of the various features thereof. 
     The plug assembly  150  generally includes, moving radially outward, a data connector  651 , an intermediate circumferential gap  654 , an intermediate annular portion  655 , an outer circumferential gap  656 , and an outer annular portion  657 . The data connector  651  is provided in the radially inner portion  650   a  of the plug assembly  150  and includes a female data terminal  651   a  and an annular member  651   b  (e.g., plug shield component), which are separated by an inner circumferential gap  652 . The plug assembly  150  additionally includes at least two power terminals  658  (e.g., contacts), which are provided in the radially outer portion  650   b  of the plug assembly  150 , as well as one or more annular seal members  459  (e.g., annular seal; shown in  FIG. 4 ). The two power terminals  658  may be power and ground terminals. The power terminals  658  may also be referred to as contacts (e.g., a power contact and a ground contact). The female data terminal  651   a  may also be referred to as a data contact. 
     The female data terminal  651   a  and the annular member  651   b  of the data connector  651  of the plug assembly  150  are electrically coupled, respectively, to the data conductor  561  and the shielding layer  563  of the cable  160 . 
     The female data terminal  651   a  of the data connector  651  is additionally configured to receive therein a male data pin  921   a  of data connector  821  of the receptacle assembly  120  to electrically couple therewith for data transfer. Similarly, the annular member  651   b  is configured to receive therein another annular member  921   b  of the data connector  821  to electrically couple therewith to form a continuous shield. It should be noted, however, that these male/female relationships may be reversed, such that the data connector  651  of the plug assembly  150  instead includes a male data pin and an annular member that are received within a female data terminal and an annular member of the data connector  821  of the receptacle assembly  120 . The data connector  821  of the receptacle assembly  120  is discussed in further detail below. The male data pin  921   a  and the female data terminal  651   a  may each be referred to as a data terminal. 
     The intermediate circumferential gap  654  separates the data connector  651  from the intermediate annular member  655  and the power terminals  658 , and is configured to receive therein an annular portion  930   c  of a body member  840  (e.g., molded body) of the receptacle assembly  120 , which are discussed in further detail below. 
     The intermediate annular member  655  of the plug assembly  150  is non-conductive and includes a radially inner portion  655   a  and a radially outer portion  655   b . The radially inner portion  655   a  has a smaller outer diameter and extends axially further than radially outer portion  655   b . A step is, thereby, formed at the axial transition between the radially inner portion  655   a  and the radially outer portion  655   b . The radially outer portion  655   b  of the intermediate annular member  655  additionally includes a plurality of circumferentially spaced recesses  655   c , which correspond to and have received therein the power terminals  658 . 
     The power terminals  658  of the plug assembly  150  are conductive members that are each electrically coupled to one of the power conductors  568  of the cable  160 . Each power terminal  658  is positioned in one of the recesses  655   c  of the intermediate annular member  655 . Each power terminal  658  faces radially outward to receive thereagainst a corresponding power terminal  828  (e.g., power and ground terminals) of the receptacle assembly  120  to electrically connect therewith, as discussed in further detail below. 
     Outer surfaces of the power terminals  658  are spaced apart a greater distance than the outer surface of the radially inner portion  655   a  and a lesser distance then the outer surface of the radially outer portion  655   b . As such, the outer surfaces of the power terminals  658  are radially recessed relative to the outer surface of the radially outer portion  655   b  and radially proud of the outer surface of the radially inner portion  655   a.    
     The outer circumferential gap  656  of the plug assembly  150  is configured to receive another outer annular portion  1340   c  and the power terminals  828  of the receptacle assembly  120  therein, as discussed in further detail below. 
     The outer annular portion  657  and the annular seal members  459  of the plug assembly  150  are configured to be received in and form a seal with a recess  1147  of the receptacle assembly  120 , as discussed in further detail below. 
     The receptacle assembly  120  is configured to receive the plug assembly  150  to transfer electrical power and data therewith. The receptacle assembly  120  is additionally configured to shield electronic components (e.g., the controller  102 , PCB, or other electronic components in the enclosure  104 ) from electromagnetic interference that might otherwise be caused by the power connection of the connector system  110  or otherwise transferred thereto. The receptacle assembly  120  and the plug assembly  150  are also configured to physically engage each other to form a mechanical connection therebetween, while also preventing intrusion of water and debris and maintain robust power and data connections in view of noise, vibration, and harshness (NVH) inputs to the connector system  110 . 
     Referring to  FIGS. 2 and 8-15 , the receptacle assembly  120  generally includes a data connector  821 , two or more power terminals  828 , a shield structure  830  (e.g., shield) that includes or is coupled to a front plate  838  (e.g., a forward shield structure), and a body member  840  (e.g., molded component, body, or insert). The two or more power terminals  828  may also be referred to as contacts (e.g., a power contact and a ground contact). 
     Referring to the partial views in  FIGS. 9-10 , the shield structure  830  of the receptacle assembly  120  is configured to prevent electromagnetic interference (e.g., electrical noise) caused by any source within the vehicle  100  or an environment of the vehicle  100  from entering the enclosure  104  and impacting the controller  102  or other electrical components (e.g., PCB) therein. For example, the cable  160  might otherwise act as an antenna and form a pathway by which the electrical noise might otherwise enter the enclosure  104 . The shield structure  830  of the receptacle assembly  120  is electrically coupled to the shielding layer  563  of the cable  160  and to the enclosure  104 . The shield structure  830  thereby provides a path (e.g., a shield pathway), which electrically couples (e.g., grounds) the shielding layer  563  of the cable  160  to the shield structure  830  to the enclosure  104 . The shield structure  830  substantially surrounds the power connection that is formed by physical contact between the power terminals  658 ,  828 , respectively, of the plug assembly  150  and the receptacle assembly  120  with the power connections being electrically insulated or isolated from the shield structure  830  (e.g., such that power pathways, such as power and ground pathways or paths, formed by the power connections thereby passes through the shield structure  830  without making contact therewith). The shield structure  830  also substantially surrounds the data connections formed by the physical contact between the data connectors  651 ,  821  of the plug assembly  150  and the receptacle assembly  120  with the data connections being electrically insulated or isolated from the shield structure  830  (e.g., such that data pathways or paths formed thereby pass through the shield structure  830  without making contact therewith). 
     For example, the shield structure  830  is a box structure formed of or otherwise comprising appropriate metal material used for electromagnetic shielding. The shield structure  830  defines a cavity  930   a  (e.g., recess) in which the data connector  821  and the power terminals  828  are positioned. As referenced above, and as is shown in  FIG. 1 , the shield structure  830  may be recessed into and/or electrically coupled to the enclosure  104 . 
     The enclosure  104  is itself made from an electrically conductive material (e.g., metal and/or conductive polymer) and surrounds (e.g., partially, substantially, or entirely) the controller  102 , PCB, or other electronic components in the enclosure  104 . The enclosure  104  is configured to shield components contained therein from electromagnetic interference, and may be referred to as an electromagnetic shield enclosure. With the shield structure  830  being electrically coupled to both the shielding layer  563  of the cable  160  and the enclosure  104 , the shield structure  830  forms the shield pathway, which electrically connects (e.g., grounds) the shielding layer  563  to the enclosure  104  to prevent propagation of electromagnetic interference into the enclosure  104 . 
     In one example, the shield structure  830  is a multi-component assembly. The shield structure  830  includes a back plate  932  and a peripheral shell  934 , which cooperatively form a rear shield structure and define the cavity  930   a  therein. The back plate  932  forms a rear surface  932   a  of the cavity  930   a . The back plate  932  additionally includes apertures (e.g., apertures  932   c ) through which the data connector  821  and the power terminals  828  extend into the cavity  930   a , so as to be substantially surrounded by the shield structure  830 . The back plate  932  includes flanges  932   b  (e.g., tabs, extensions, etc.) that are bent forward from the rear surface  932   a  (e.g., at a 90 degree angle, represented by the broken lines in  FIG. 9 ), and which are electrically and physically coupled to mating surfaces of the peripheral shell  934  (e.g., via laser welding). 
     The peripheral shell  934  of the shield structure  830  forms outer walls  934   a  (e.g., four to form a rectangle or square cross-section) of the shield structure  830 . The outer walls  934   a  extend rearward from forward edges  934   b  (e.g., forward peripheral edge) thereof to or beyond the rear surface  932   a  of the back plate  932 . The forward edges  934   b  of the peripheral shell  934  include a plurality of members  934   c  (e.g., fingers, protrusions, etc.) formed integrally therewith. The members  934   c  are bent or curved inward from the outer walls  934   a  toward the cavity  930   a . The members  934   c  are spaced apart from each other and cooperatively form the forward edge  934   b  for receiving and forming an electrical connection with the front plate  838 . Among other considerations, maximum dimensions of the gaps or voids between the members  934   c  may be determined according to the lowest wavelength (and the highest frequency) of the electromagnetic frequency expected. For example, the maximum dimension of the void between the members  934   c  may be between 1.5 and 10 mm (e.g., approximately 1.5 mm, which corresponds to electromagnetic interference having a frequency of approximately 20 GHz). 
     Instead of or in addition to the members  934   c , a conductive gasket may instead be arranged (e.g., compressed) between the peripheral shell  934  and the front plate  838  to form an electrical connection therebetween and continuously around the shield structure  830 . 
     Thus, the shield structure  830  substantially surrounds the electrical and data connections formed by the physical contact between the data connectors  651 ,  821  and the power terminals  658 ,  828  of the plug assembly  150  and the receptacle assembly  120 , respectively, by extending behind (e.g., with the back plate  932 ), around, and forward (e.g., with the outer walls  934   a ) of such physical contact, while having a forward opening for receiving the plug assembly  150 . In other embodiments, the shield structure  830  may be configured in other manners including, for example, comprising fewer or more components (e.g., one integrally formed component, or more than two components coupled together), being proud of or flush with the enclosure  104 , or other suitable configurations. 
     Referring to the partial views in  FIGS. 11-12 , as well as the cross-sectional views in  FIGS. 13-15 , the body member  840  is configured to receive the plug assembly  150  and other connectors (e.g., data-only) to form a mechanical connection therewith, so as to facilitate and maintain electrical connections with the data connector  821  and the power terminals  828 . 
     The body member  840  may be a polymer component that may be insert-molded with the shield structure  830 , so as to be directly coupled to the shield structure  830 . The body member  840  includes a forward portion  1140   a  that is positioned within the cavity  930   a  of the shield structure  830 , and may also include a rearward portion  1330   b  (best seen in the cross-sectional view of  FIG. 13 ). The rear portion  1340   b  is formed continuously with the forward portion  1140   a  or may be separated therefrom by the shield structure  830  (e.g., being a separate component), but in either instance may be formed via the insert molding process. In other embodiments, the body member  840  may be made from another type of material and and/or be made with or coupled to the shield structure  830  in other manners. 
     The forward portion  1140   a  of the body member  840  defines one or more recesses  1147  (e.g., recesses) configured to receive one of the plug assemblies  150  or other connectors (e.g., for data-only; not shown). Each recess  1147  includes therein the power terminals  828  and the data connector  821 . Each recess  1147  is of sufficient axial depth to receive the plug assembly  150  there to make appropriate electrical contact between the data connector  821  and the power terminals  828  of the receptacle assembly  120  with the data connector  651  and the power terminals  658 , respectively, of the plug assembly  150 . 
     The forward portion  1140   a  of the body member  840  is additionally configured to seal with the front plate  838 . More particularly, the forward portion  1140   a  of the body member  840  includes a protrusion  1140   d , along with a seal member  1132  surrounding the protrusion  1140   d . The protrusion  1140   d  is received in a complementary aperture (not labeled) in the front plate  838 , and may be flush with a forward surface thereof. 
     The seal member  1132  engages and is compressed by a rear surface of the front plate  838  to form a seal between the body member  840  to prevent intrusion of liquids and/or debris into and/or through the receptacle assembly  120 . Prior to the front plate  838  being coupled to the receptacle assembly  120 , the seal member  1132  is in a relaxed, uncompressed state and is positioned forward of the members  934   c  of the peripheral shell  934  of the shield structure  830 . 
     The front plate  838  extends laterally outward from the cavity  930   a  and may also extend laterally inward for the shield structure  830  to further surround the electrical connections (i.e., the physical contact between the data connectors  651 ,  821  and the power terminals  658 ,  828  of the plug assembly  150  and the receptacle assembly  120 ). The front plate  838  is electrically coupled to the shield structure  830  by contacting and/or being welded to the members  934   c  of the shield structure  830  and/or by both contacting a conductive gasket, as referenced above. The front plate  838  is additionally mechanically coupled directly or indirectly to the shield structure  830  to sufficiently compress the seal member  1132  therebetween to prevent intrusion of water and/or debris therebetween. For example, the front plate  838  may be coupled to the shield structure  830  with mechanical fasteners (e.g., screws or other elongated fasteners) or laser welding (e.g., to the members  934   c ), other features of or exterior to the shield structure  830  (e.g., tabs, or clips), or other fasteners or other features that draw the back plate  932  and the front plate  838  toward each other (e.g., fasteners extending through the body member  840 ). Furthermore, the front plate  838  may be part of or coupled to the enclosure  104 , such that the enclosure  104  is also mechanically and/or electrically coupled to the shield structure  830 . 
     Referring to  FIGS. 11-15 , the data connector  821  of the receptacle assembly  120  is positioned centrally within the recess  1147  and laterally (e.g., radially) between the power terminals  828 . This arrangement of the data connector  821  between the power terminals  828  in the receptacle assembly  120  corresponds to that for the data connector  651  and the power terminals  658  of the plug assembly  150 . 
     Referring to  FIGS. 9 and 13-15 , the data connector  821  extends rearward through the back plate  932  of the shield structure  830 . As referenced previously, the data connector  821  generally includes a male data pin  921   a  and an annular member  921   b . The data connector  821  may also be referred to as a data contact. The male data pin  921   a  may also be referred to as a data conductor, while the annular member may  921   b  may be referred to as a shield member. 
     As shown in  FIG. 13 , in a forward region forward of the back plate  932  of the shield structure  830 , the data connector  821  includes an inner circumferential gap  1321   c  that separates the male data pin  921   a  and the annular member  921   b . In a rearward region behind the back plate  932 , the data connector includes one or more insulators or mechanical couplings  1321   d ,  1321   e  arranged between the male data pin  921   a  and the annular member  921   b . The male data pin  921   a  may, for example, be positioned axially rearward of a forward end of the annular member  921   b , and extend rearward through the back plate  932  of the shield structure  830  (e.g., to be electrically coupled to the controller  102  or other electronic component). The annular member  921   b  is electrically coupled to the back plate  932  of the shield structure  830  and may also extend therethrough. 
     When the plug assembly  150  is inserted in the recess  1147  of the receptacle assembly  120 , the male data pin  921   a  of the data connector  821  of the receptacle assembly  120  is received within and contacts the female data terminal  651   a  of the data connector  651  of the plug assembly  150  to form an electrical connection therebetween. Furthermore, the annular member  651   b  of the data connector  651  of the plug is received within and contacts the annular member  921   b  of the data connector  921  of the receptacle assembly  120  to form an electrical connection therebetween, which also electrically couples the shield structure  830  to the shielding layer  563  of the cable  160 . With this electrical contact, data and shield connections are formed between the plug assembly  150  and the receptacle assembly  120 . 
     The power terminals  828  extend through apertures  932   c  in the back plate  932 . The power terminals  828  are separated from the annular member  921   b  of the data connector  821  with an intermediate circumferential gap  1340   e  and an annular portion  1340   c  of the body member  840 . The annular portion  1340   c  of the body member  840  may, for example, be coupled to the rear portion  1340   b  of the body member  840  through the apertures  932   c  in the back plate  922 , such as being formed therewith during the insert-molding process. The power terminals  828  each extend axially along a radially outer surface of the annular portion  1340   c , and include a protrusion  1328   a  that protrudes radially inwardly through apertures (not labeled) of the annular portion  1340   c  toward, but not in contact with, the annular member  921   b  of the data connector  821 . 
     When the plug assembly  150  is inserted in the recess  1147  of the receptacle assembly  120 , the intermediate annular member  655  of the plug assembly  150 , along with the power terminals  658 , is received in the gap  1340   e . Moreover, the protrusions  1328   a  of the power terminals  828  in the receptacle assembly  120  are received against the power terminals  658  of the plug assembly  150  to electrically couple therewith. With this electrical contact, a power connection is formed between the plug assembly  150  and the receptacle assembly  120 . 
     The protrusions  1328   a  of the power terminals  828  of the receptacle assembly  120  may also be positioned within the recesses  655   c  of the intermediate annular member  655  of the plug assembly  150 , which may function to mechanically align the plug assembly  150  with the receptacle assembly  120 . 
     An outer circumferential gap  1340   f  is positioned radially outward from the annular portion  1340   c  of the body member  840  and the power terminals  828 . When the plug assembly  150  is inserted in the recess  1147  of the receptacle assembly  120 , the outer annular portion  657  of the plug assembly  150  is received within the outer circumferential gap  1340   f.    
     The outer annular portion  657  of the plug assembly  150  thereby engages the body member  840  of the receptacle assembly  120  to form a mechanical and/or sealing connection therewith. More particularly, the recess  1147  has an inner periphery  1347   a  (e.g., an inner radial surface) that is complementary to the outer annular portion  657  and the annular seal members  459  of the plug assembly  150 . For example, the inner periphery  1347   a  has a diameter that is slightly larger an outer diameter of the outer annular portion  657  of the plug assembly  150  and slightly smaller than an outer diameter of the annular seal members  459 , thereby allowing receipt of the plug assembly  150  therein and compressing the annular seal members  459  to form a seal against the inner periphery  1347   a  of the body member  840 . 
     Referring to  FIGS. 17A-21D , another connector system  1710  is configured to transfer both electrical power and signals (e.g., control and/or data signals), for example, between the power source  101  and/or the controller  102  and the module  103  located remotely thereto (see  FIG. 1 ). The connector system  1710  generally includes a receptacle assembly  1720  coupled to an enclosure  1702  (shown partially) and a plug assembly  1750 . The enclosure  1702  is a metal enclosure (e.g., a metal box) of which only a single wall  1702   a  is shown and in which a circuit board (e.g., PCB) may be positioned. The wall  1702   a  may be a forwardmost wall of the enclosure  1702  or may be recessed relative to other portions of the enclosure  1702  and/or surrounding components (e.g., functional and/or aesthetic covers). The receptacle assembly  1720  is configured to receive the plug assembly  1750  to provide combined power and data connections, more particularly, by providing power transfer and data transfer via separate electrical connections, as well as provide a mechanical connection therebetween. The receptacle assembly  1720  may also be referred to as a receptacle, receiver, base, female assembly, or female connector. The plug assembly may also be referred to as a plug, plug connector, male assembly, or male connector. 
     The connector system  1710  is configured to provide electromagnetic shielding to prevent or limit interference that might otherwise occur, for example, due to relatively high electrical output of the power connections (e.g., 48V or 60V at approximately 15 amps), due to close proximity of other electronic components to the power and data connections, and/or due to a high prevalence of interference sources in the vehicle  100  (e.g., electric powertrain, etc.). The connector system  1710  is additionally configured to provide a sealed connection between the receptacle assembly  1720  and the plug assembly  1750  to prevent intrusion of external conditions (e.g., rain, snow, dust, etc.) that may be prevalent in vehicular applications. 
     Referring additionally to  FIG. 18 , the receptacle assembly  1720  generally includes a housing  1822 , a shield plate  1824 , a power contact  1826 , a ground contact  1828 , and a data contact  1830 . Generally speaking, the power contact  1826  and the ground contact  1828  are configured to transfer or conduct electricity between components internal to and external from the enclosure  1702 . The data contact  1830  is configured to transfer data between data components internal to and external from the enclosure  1702 . The shield plate  1824  provides electromagnetic shielding. The housing  1822  is mechanically connected to each of the power contact  1826 , the ground contact  1828 , and the data contact  1830  and to the enclosure  1702 , and is further configured to removably receive the plug assembly  1750 . The power contact  1826 , the ground contact  1828 , and the data contact  1830  may also be referred to as terminals. 
     When referring to various features (e.g., the receptacle assembly  1720 , the plug assembly  1750 , the power contact  1826 , the ground contact  1828 , and the data contact  1830 ), such features and various aspects thereof (e.g., components, features, portions, etc.) thereof may be identified using terms associated therewith (e.g., receptacle, plug, power, ground, or data), numerically (e.g., first, second, third, etc.), and/or in the alternative (e.g., another), so as to distinguish from other features and aspects of the connector system  1710 . For example, a “contact portion” of the power contact  1826  may be referred to or identified as a “power contact portion,” so as to distinguish from a “contact portion” of the ground contact  1828  referred to or identified as a “ground contact portion.” The ground contact  1828  may also be referred to as a contact, while the power contact may be referred to as another power contact  1826 . The power contact  1826 , the ground contact  1828 , and the data contact  1830  may also be referred to as a first contact, a second contact, and a third contact, while contact portions thereof may be referred to as a first contact portion, a second contact portion, and a third contact portion, respectively. 
     Referring first to the power contact  1826 , the power contact generally includes a contact portion  1826   a , a conductor portion  1826   b , and a coupling portion  1826   c . The contact portion  1826   a  is configured to physically contact and, thereby, electrically connect to a corresponding portion of the plug assembly  1750  as discussed in further detail below. As shown, the contact portion  1826   a  may have a curved cross-section extending in an axially forward direction away from the enclosure  1702 , for example, forming a partially cylindrical surface. The power contact  1826  may also be referred to as a contact, contact assembly, or contact structure. The contact portion  1826   a  may also be referred to as a contact segment. 
     The conductor portion  1826   b  extends from the contact portion  1826   a  into the enclosure  1702 , for example, to connect to a circuit board (not shown) arranged therein. As shown, the conductor portion  1826   b  may extend transversely from a lower end the contact portion  1826   a  (e.g., cooperatively forming an L-shape in cross-section), as well as axially rearward thereof. The conductor portion  1826   b  of the power contact  1826  includes multiple conductor segments  1826   b ′ (e.g., three as shown), which are cooperatively configured (e.g., sized) to satisfy power transfer requirements (e.g., 48V or 60V at 15 amps, as referenced above). Each of the conductor segments  1826   b ′ (e.g., three as shown) may extend axially rearward into the enclosure  1702 , and bend transversely (e.g., downward and/or forming an L-shape) for receipt in corresponding connectors of the circuit board. For example, as shown, the conductor segments  1826   b ′ may extend axially in parallel axes in a first plane, and bend to extend vertically downward in parallel axes in a second plane perpendicular to the first plane. Those portions of the conductor segments  1826   b ′ extending axially may be referred to as axial portions, while those portions extending transversely may be referred to as transverse portions. The conductor segments  1826   b ′ may extend a common distance to terminate at a common elevation. As a result, the conductor segments  1826   b ′ of the power contact  1826  may be received in corresponding connectors (e.g., receptacles) of a circuit board that may be arranged horizontally (e.g., parallel with the axis of the receptacle assembly  1720 ) in the enclosure  1702 . In other embodiments, the conductor portion  1826   b  and the conductor segments  1826   b ′ may be configured in other manners, for example, by being provided in different numbers (e.g., less than or more than three). Still further, the conductor segments  1826   b ′ may extend only in an axial direction (e.g., without being bent), so as to be received in corresponding connectors (e.g., receptacles) of a vertical circuit board (e.g., perpendicular to the axis of the receptacle assembly  1720 ) in the enclosure  1702 . 
     Each of the contact portion  1826   a  and the conductor portion  1826   b , including the conductor segments  1826   b ′, are formed of a suitable electrically conductive material, such as a copper alloy. The contact portion  1826   a  and the conductor portion  1826   b  may be a singular member, for example, being formed via a stamping operation. The contact portion  1826   a  and the conductor portion  1826   b  may, collectively, be referred to as a conductive member or structure of the power contact  1826 . 
     The coupling portion  1826   c  of the power contact  1826  is configured to mechanically connect to the housing  1822 . The coupling portion  1826   c  is received in a corresponding recess or aperture of the housing  1822  (e.g., L-shaped in cross-section and discussed in further detail below), of the housing  1822  to be mechanically connected thereto (e.g., via a press-fit, adhered, or other form of mechanical connection or combinations thereof). 
     The coupling portion  1826   c  may also be configured to insulate the conductor portion  1826   b  of the power contact  1826  from the shield plate  1824 . For example, the coupling portion  1826   c  may include cylindrical portions  1826   c ′ (e.g., sheaths or sheath portions) that are each associated with one of the conductor segments  1826   b ′ that extends therethrough. The cylindrical portions  1826   c ′, along with the conductor segments  1826   b ′, extend through apertures (discussed below). of the shield plate  1824  and prevent physical and, thereby, conductive contact between the conductor segments  1826   b ′ and the shield plate  1824 . 
     The coupling portion  1826   c  is, for example, a polymer material (e.g., nylon) that is overmolded to an intermediate region (hidden by the coupling portion  1826   c ) of the conductive member that forms the contact portion  1826   a  and the conductor portion  1826   b . The coupling portion  1826   c  may also be referred to as a plastic, overmolded, or insulative portion or structure. The power contact  1826  may also be referred to as an overmolded contact structure. 
     The ground contact  1828  is configured similarly to the power contact  1826 , for example, by generally including a contact portion  1828   a , a conductor portion  1828   b , and a coupling portion  1828   c . Referring additionally to  FIGS. 21A-21D , as arranged in the receptacle assembly  1720 , the contact portion  1828   a , the conductor portion  1828   b , and the coupling portion  1828   c  of the ground contact  1828  are generally radially opposite the contact portion  1826   a , the conductor portion  1826   b , and the coupling portion  1826   c , respectively, of the power contact  1826  relative to an axis of the receptacle assembly  1720 . For example, the contact portion  1828   a  of the ground contact  1828  may be positioned horizontally across from the contact portion  1826   a  of the power contact  1826 , for example, forming an opposite portion of a cylindrical surface. The ground contact  1828  may also be referred to as a contact, contact assembly, or contact structure. The contact portion  1828   a  may also be referred to as a contact segment. 
     A forward region of the conductor portion  1828   b  of the ground contact may be positioned vertically across from the conductor portion  1826   b  of the power contact  1826 . The conductor portion  1828   b  includes multiple conductor segments  1828   b ′, which extend axially further rearward than the conductor portion  1826   b  of the power contact  1826 . The conductor segments  1828   b ′ (e.g., three as shown), then bend transversely (e.g., downward and/or forming an L-shape) for receipt in corresponding connectors of the circuit board. For example, as shown, the conductor segments  1828   b ′ may extend axially in parallel axes in a third plane (e.g., parallel with the first plane associated with the axial portions of the conductor segments  1826   b ′), and bend to extend vertically downward in parallel axes in a second plane perpendicular to the third plane (e.g., parallel with the second plane associated with the transverse portions of the conductor segments  1826   b ′). Those portions of the conductor segments  1828   b ′ extending axially may be referred to as axial portions, while those portions extending transversely may be referred to as transverse portions. As shown, the transverse portions of the conductor segments  1828   b ′ may be laterally offset from the transverse portions of the conductor segments  1826   b ′ of the power contact  1826 . In other embodiments, the conductor portion  1828   b  and the conductor segments  1828   b ′ may be configured in other manners, for example, by being provided in different numbers (e.g., less than or more than three). The power contact  1826  and the ground contact  1828  may be arranged in alternative manners relative to each other, for example, with the conductor segments  1826   b ′ of the power contact  1826  may instead extend further rearward than the conductor segments  1828   b ′ of the ground contact  1828 . The ground conductor segments  1828   b ′ may also extend axially (without bending) for receipt in a vertical circuit board as referenced above. 
     For further details of the ground contact  1828 , including the contact portion  1828   a , the conductor portion  1828   b , and the coupling portion  1828   c  of the ground contact  1828 , refer to generally to the discussion of the power contact  1826  above, including discussion of the contact portion  1826   a , the conductor portion  1826   b , and the coupling portion  1826   c , respectively. 
     The data contact  1830  generally includes a shield member  1830   a , conductor  1830   b , and a dielectric  1830   c . The data contact  1830  extends axially forward away from the enclosure  1702  to connect with corresponding portions of the plug assembly  1750  (i.e., corresponding shield and data portions), extends axially rearward into the enclosure  1702 , and bends transversely for connection to the circuit board (e.g., being L-shaped). More particularly, as arranged in the receptacle assembly  1720 , the data contact  1830  is positioned between (e.g., is surrounded by) the power contact  1826  and the ground contact  1828  (e.g., in axially forward regions outside the enclosure  1702 , and in axially rearward regions inside the enclosure  1702 ). 
     The shield member  1830   a  is a substantially tubular member or structure through which the conductor  1830   b  and the dielectric  1830   c  extend. A forward portion  1830   a ′ of the shield member  1830   a  extends through a corresponding aperture (discussed further below) of the shield plate  1824 . The forward portion  1830   a ′ may also physically contact and, thereby, electrically couple the shield member  1830   a  to the shield plate  1824 . A rearward portion  1830   a ″ of the shield member  1830   a  may have a larger cross-section than the forward portion  1830   a ′ and the aperture of the shield plate  1824 , such that the rearward portion  1830   a ″ physically contacts (e.g., axially abuts) and, thereby, electrically couples the shield member  1830   a  to the shield plate  1824 . The rearward portion  1830   a ″ extends axially from the forward portion  1830   a ′ and additionally bends transversely thereto to connect to the circuit board in the enclosure  1702  (e.g., forming an L-shape). The shield member  1830   a  may, for example, be formed of a conductive metal material, such as stainless steel or material plated with stainless steel. 
     The conductor  1830   b  extends through the shield member  1830   a  and is electrically isolated or insulated therefrom, for example, by way of the dielectric  1830   c  or an air gap in various regions. The conductor  1830   b  extends axially forward from the enclosure  1702 , axially rearward into the enclosure  1702 , and bends transversely downward toward the circuit board (e.g., forming an L-shape). As arranged in the receptacle assembly  1720 , the conductor  1830   b  extends parallel with and between the conductor segments  1826   b ′ of the power contact  1826  and the conductor segments  1828   b ′ of the ground contact  1828  and may terminate at a common distance (e.g., elevation) therewith for connection to the circuit board. For example, an axial portion of the conductor  1830   b  extends parallel with the axial portions of the conductor segments  1826   b ′ and between the conductor segments  1828   b ′, and a transverse portion of the conductor  1830   b  extends parallel with and between the transverse portions of the conductor segments  182   b ′ and the conductor segments  1828   b′.    
     The conductor  1830   b  may, for example, be made of copper alloy (e.g., brass). The conductor  1830   b  may also be referred to as a pin. 
     The shield plate  1824  allows the conductor segments  1826   b ′ of the power contact  1826 , the conductor segments  1828   b ′ of the ground contact  1828 , and the data contact  1830  to extend therethrough, while also providing electromagnetic shielding to prevent electromagnetic interference that might otherwise impact data signals. More particularly, the shield plate  1824  provides electromagnetic shielding across an aperture  1802   b  (e.g., enclosure aperture) of a wall  1702   a  of the enclosure  1702  through which the receptacle assembly  1720  extends. The shield plate  1824  is electrically coupled to the enclosure  1702  with the shield plate  1824  physically contacting the wall  1702   a . For example, a surface of the shield plate  1824  faces and abuts the wall  1702   a  of the enclosure  1702  surrounding the aperture  1802   b.    
     As referenced above, the shield plate  1824  includes apertures through which the conductor segments  1826   b ′ of the power contact  1826 , the conductor segments  1828   b ′ of the ground contact  1828 , and the data contact  1830  extend. More particularly, to provide high levels of electromagnetic shielding for high speed data transfer simultaneous with high power transfer (e.g., high current), multiple power apertures  1824   a  (i.e., for power conductor segments to pass therethrough) and multiple ground apertures  1824   b  (i.e., for ground conductor segments to pass therethrough) are provided. 
     The size of and spacing between the power apertures  1824   a  and the ground apertures  1824   b  may be configured to optimize or otherwise improve electromagnetic shielding. Among other considerations, the maximum size (e.g., diameter or other dimension) of the power apertures  1824   a  and the  1824   b  may be determined according to the lowest wavelength (and conversely the highest frequency) of the electromagnetic frequency expected. For example, the maximum dimension of the power apertures  1824   a  and the ground apertures  1824   b  may be between 1.5 and 10 mm (e.g., approximately 1.5 mm, which corresponds to electromagnetic interference having a frequency of approximately 20 GHz). For example, the power apertures  1824   a  and/or the ground apertures  1824   b  may have a diameter of up to 1.5 mm (e.g., having a 1.5 mm diameter). The power apertures  1824   a  are spaced apart laterally from each other, as are the ground apertures  1824   b  are spaced apart laterally from each other 
     As compared to power transfer and shielding by singular, larger power and ground conductors extending through singular, larger apertures through a shield structure, similar power transfer with improved shielding may be provided by multiple, smaller ones of the power conductor segments  1826   b ′ and ground conductor segments  1828   b ′ extending through corresponding, smaller ones of the power apertures  1824   a  and the ground apertures  1824   b . The shield plate  1824  also includes a data aperture  1824   c , which is central to the shield plate  1824 , such as being generally concentric with the shield plate  1824 . The data aperture  1824   c  may also be arranged between (e.g., radially between) a first group of the power apertures  1824   a  and second group of the ground apertures  1824   b . The power apertures  1824   a  in the first group may be arranged in a straight line across the shield plate  1824  (i.e., such that the straight line passes through axes of the power apertures  1824   a ). The ground apertures  1824   b  in the second group may be arranged in another straight line across the shield plate  1824  (e.g., in such that the other straight line passes through axes of the ground apertures  1824   b  and may be parallel with the line). Alternatively, the power apertures  1824   a  and/or the ground apertures  1824   b  may be arranged in arcs, such as being concentric with an axis of the data aperture  1824   c.    
     The shield plate  1824  may, for example, be a stamped component formed of stainless steel. The shield plate  1824  may also be referred to as a shield, shield member, or shield structure. 
     As referenced above, the housing  1822  is configured to mechanically connect to the power contact  1826 , the ground contact  1828 , and the data contact  1830 . The housing  1822  is additionally configured to mechanically and sealingly connect to the enclosure, as well as receive and removably retain the plug assembly  1750 . 
     The housing  1822  generally includes a primary housing structure  1834 , an external housing structure  1836 , and an internal housing structure  1838 . 
     The primary housing structure  1834  is positioned within the aperture  1802   b  of the wall  1702   a  of the enclosure  1702 , and protrudes from the enclosure  1702 . The primary housing structure  1834  may be generally tubular, for example, being generally circular in cross-sectional shape (e.g., annular) or having other cross-sectional shapes at one or more axial locations. The primary housing structure  1834  may, for example, be a unitary member made of a polymer material (e.g., polyamide), for example, via an injection molding process. The primary housing structure  1834  may, alternatively, be a multi-piece component, be made of another material, and/or be made from another manufacturing process. The primary housing structure  1834  may also be referred to as a primary or housing member or structure. 
     To mechanically connect to the plug assembly  1750 , the primary housing structure  1834  defines a primary recess  1734   a  for selectively receiving the plug assembly  1750  therein. The primary recess  1734   a  faces away from the enclosure  1702 , for example, in a forward direction. The primary housing structure  1834  may additionally include a locking feature  1834   a , such as an aperture or recess, to receive a corresponding locking feature of the plug assembly  1750  (as discussed in further detail below). 
     The power contact  1826 , the ground contact  1828 , and the data contact  1830  are additionally mechanically connected to the primary housing structure  1834  and held stationary thereto, for example, to prevent movement relative to the shield  1824 . Thereby, the contact portion  1826   a  of the power contact  1826 , the contact portion  1828   a  of the ground contact  1828 , and forward portions (e.g., contact portions) of the shield member  1830   a  and conductor  1830   b  of the data contact  1830  are stably arranged in the primary recess  1734   a  of the primary housing structure  1834 . 
     More particularly, referring to  FIGS. 19A-19F , the primary housing structure  1834  includes various apertures or recesses that face toward the enclosure  1702  (e.g., in a rearward direction) and in which are received the power contact  1826 , the ground contact  1828 , and the data contact  1830 . The primary housing structure  1834  includes a power recess  1934   b , a ground recess  1934   c , and a data recess  1934   d . The power recess  1934   b  is substantially L-shaped in cross-section, so as to receive therein and couple to the coupling portion  1826   c  of the power contact  1826 . The power recess  1934   b  extends to the primary recess  1734   a  of the primary housing structure  1834 , such that the contact portion  1826   a  of the power contact  1826  is arranged therein. The power recess  1934   b  also faces an interior of the enclosure  1702 , such that the conductor portion  1826   b  (i.e., the conductor segments  1826   b ′) of the power contact  1826  is arranged in the enclosure  1702 . Thus, the power contact  1826  extends from the primary recess  1734   a  of the primary housing structure  1834  through the power recess  1934   b  into the enclosure  1702 . 
     Similarly, the ground recess  1934   c  is L-shaped in cross-section, so as to receive therein and couple to the coupling portion  1828   c  of the ground contact  1828 . The ground recess  1934   c  extends to the primary recess  1734   a  of the primary housing structure  1834 , such that the contact portion  1828   a  of the ground contact  1828  is arranged therein. The ground recess  1934   c  also faces the interior of the enclosure  1702 , such that the conductor portion  1828   b  (i.e., the conductor segments  1828   b ′) of the ground contact  1828  is arranged in the enclosure  1702 . Thus, the ground contact  1828  extends from the primary recess  1734   a  of the primary housing structure  1834  through the ground recess  1934   c  into the enclosure  1702 . 
     The data recess  1934   d  is substantially circular in cross-section, so as to receive therein and couple to the data contact. The data recess  1934   d  is generally surrounded by the power recess  1934   b  and the ground recess  1934   c . The data recess  1934   d  extends to the primary recess  1734   a  of the primary housing structure  1834 , such that the contact portions of the data contact  1830  are arranged therein. The data recess  1934   d  also faces the interior of the enclosure  1702 , such that the data contact  1830  extends into the enclosure  1702 . Thus, data contact  1830  extends from the primary recess  1734   a  of the primary housing structure  1834  through the data recess  1934   d  into the enclosure  1702 . 
     The external housing structure  1836  is configured to mechanically connect and seal the receptacle assembly  1720  to the enclosure  1702 . The external housing structure  1836  is a generally annular structure or member. More particularly, the external housing structure  1836  is configured as a nut, which is threadably received by the primary housing structure  1834  (see threads in  FIGS. 21A-21D ). When tightened thereon, the external housing structure  1836  compresses the wall  1702   a  of the enclosure  1702  between the external housing structure  1836  and the shield plate  1824 . Furthermore, the external housing structure  1836  may include or otherwise engage compressible seal members. For example, the external housing structure  1836  may compress in an axial direction a gasket  1840  (e.g., elastomeric O-ring) between a peripheral portion  1836   a  (e.g., configured as a radial flange) and a surface of the wall  1702   a  of the enclosure  1702 . The gasket  1840  may be arranged in an axially facing groove of the peripheral portion  1836   a , such that the peripheral portion  1836   a  may engage the wall  1702   a  and appropriately compress the gasket  1840  thereagainst. Another gasket  1842  may be arranged and compressed radially between the primary housing structure  1834  and the external housing structure  1836 . The gasket  1840  and the gasket  1842 , thereby, cooperatively, seal the receptacle assembly  1720  to the enclosure  1702 . The external housing structure  1836  is, for example, an injection molded polymer component (e.g., polyamide). The external housing structure  1836  may also be referred to as a nut or a housing coupling member or structure. 
     The internal housing structure  1838  is arranged within the enclosure  1702  and, for example, prevents contact between the conductor segments  1826   b ′, the conductor segments  1828   b ′, and the data contact  1830 , themselves, and prevents inadvertent electrical contact with other electrical components (e.g., of the circuit board). The internal housing structure may, as shown, include a first cover member  1838   a  and a bottom cap  1838   b , each of which may be an injection molded polyamide component. 
     With further reference to  FIGS. 19A-19F , an assembly sequence of the receptacle assembly  1720  is described. As shown in  FIG. 19A , the primary housing structure  1834  is provided. 
     As shown in  FIG. 19B , the power contact  1826  and the ground contact  1828  are inserted into the power recess  1934   b  and the ground recess  1934   c , respectively. During insertion, the conductor segments  1826   b ′ of the power contact  1826  and the conductor segments  1828   b ′ of the ground contact  1828  remain straight (e.g., extending rearward parallel with an axis of the primary housing structure  1834 ). 
     As shown in  FIG. 19C , the conductor segments  1826   b ′ and the cylindrical portions  1826   c ′ of the power contact  1826  and the conductor segments  1828   b ′ and the cylindrical portions  1828   c ′ of the ground contact  1828  are inserted into the power apertures  1824   a  and the ground apertures  1824   b , respectively, of the shield plate  1824 . The shield plate  1824  is also moved axially toward the primary housing structure  1834  and abuts a rear end thereof. It should be noted that the shield plate  1824  is larger (e.g., has a larger diameter) than the primary housing structure  1834 , such that edges of the shield plate  1824  extend radially outward past edges of the primary housing structure  1834  to abut forward against in internal surface of the wall  1702   a  of the enclosure  1702  surrounding the aperture  1802   b.    
     As shown in  FIG. 19D , the conductor segments  1826   b ′ of the power contact  1826  are then bent transverse to the axis of the primary housing structure  1834 . Threaded fasteners  1938  are threaded through screw apertures  1824   d  of the shield plate  1824  and into threaded bores  1934   e  of the primary housing structure  1834  to mechanically couple the shield plate  1824  to the primary housing structure  1834 . 
     As shown in  FIG. 19E , the data contact  1830  is inserted through the data aperture  1824   c , such that the rearward portion  1830   a ″ of the data contact  1830  abuts the shield plate  1824 . 
     As shown in  FIG. 19F , the conductor segments  1828   b ′ of the ground contact  1828  are bent transversely downward (e.g., to be parallel with and terminate at a common height with the conductor segments  1826   b ′ of the power contact  1826 ). The internal housing structure  1838  is then connected to the primary housing structure  1834  with other threaded fasteners  1938  that extend through the screw apertures  1824   d  of the shield plate  1824  and into threaded bores  1934   e  of the primary housing structure  1834 . The primary housing structure  1834  may press the data contact  1830  axially against the shield plate  1824 . 
     With further references to  FIGS. 21A-21D , the receptacle assembly  1720  is then connected to the enclosure  1702 . More particularly, the primary housing structure  1834  is inserted through the apertures  1802   b  in the wall  1702   a  of the enclosure  1702  until the shield plate  1824  engages the wall  1702   a . More particularly, a rearmost portion of the primary housing structure  1834  may remain in the aperture  1802   b  of the enclosure  1702 , while the shield plate  1824  extends radially outward thereof (as noted above) and is abutted axially against an interior surface of the wall  1702   a.    
     The external housing structure  1836  is then threaded to the primary housing structure  1834 . The external housing structure  1836  is further tightened, so as to press the shield plate  1824  against the wall  1702   a  and to compress the gasket  1840  between the external housing structure  1836  and an external surface of the wall  1702   a . It should be noted that the shield plate  1824  may, rather than have a planar surface that engages the enclosure  1702 , include various protrusions, clips, or other features to ensure constant (e.g., regular or repeating) contact with the enclosure  1702  around the aperture  1802   b.    
     Referring to  FIG. 20 , the plug assembly  1750  generally includes an outer housing structure  2052 , an inner housing structure  2054 , a power contact  2056 , a ground contact  2058 , a data contact  2060 , and wire seal  2062 . Generally speaking, the power contact  2056  is configured to electrically connect a power wire  2056   a , and in particular a single conductor thereof, to the power contact  1826  of the receptacle assembly  1720  (e.g., forming a power pathway). The ground contact  2058  is configured to electrically connect a ground wire  2058   a , and in particular a single conductor thereof, to the ground contact  1828  of the receptacle assembly  1720  (e.g., forming another power or ground pathway). These single conductors may be stranded or solid, but are to be distinguished from separately insulated wires. The data contact  2060  is configured to electrically connect both a data shield and a data conductor of a data wire to the shield member  1830   a  and the conductor  1830   b  of the data contact  1830 . The outer housing structure  2052  and/or the inner housing structure  2054  are mechanically connected to the power contact  2056 , the ground contact  2058 , and the data contact  2060 . The outer housing structure  2052  is further configured be inserted into and engage the receptacle assembly  1720  to retain the plug assembly  1750  therein and seal therewith. The wire seal  2062  is configured to prevent intrusion of contaminants into the plug assembly  1750  and to align the power contact  2056 , the ground contact  2058 , and the data contact  2060  within the outer housing structure  2052 . 
     The power contact  2056  is connected to a power wire  2056   a , particularly a single conductor thereof, to conduct electricity therebetween. The power contact  2056  is further configured to physically contact and, thereby, electrically couple to the contact portion  1826   a  of the power contact  1826  in the receptacle assembly  1720 . The power contact  2056  includes multiple fingers  2056   b  (e.g., power fingers) that extend generally in an axial direction from the power wire  2056   a . The fingers  2056   b  are configured to engage the power contact  1826  of the receptacle assembly and flex (e.g., deflect) independent of each other. The fingers  2056   b  form sprung and redundant mechanical engagement with the contact portion  1826   a  of the power contact  1826  to ensure a robust electrical connection. In cross-section, in a proximal region of the power contact  2056 , the multiple fingers  2056   b  cooperatively form a transverse arc that is complementary to the curvature of the power contact  1826  of the receptacle assembly  1720 . In an intermediate region of the power contact  2056 , the fingers  2056   b  may additionally extend radially outward (e.g., flare or taper outward), so as to increase a radius of the transverse arc. In a distal region of the power contact  2056 , the fingers  2056   b  may extend axially, such that the transverse arc has a larger radius than in the intermediate region. The fingers  2056   b  are also configured to deflect independent of each other. 
     As a result of the complementary curvature (i.e., transverse arc), flared distal ends, and independent deflection, the fingers  2056   b  are configured to receive radially therein and physically contact the contact portion  1826   a  of the power contact  1826 . The power contact  2056 , thereby, electrically connects the power wire  2056   a  to the power contact  1826  of the receptacle assembly  1720 . 
     The power contact may, for example, be made of a copper alloy formed, for example, in a stamping operation. The power contact  2056  is supported by the outer housing structure  2052  and/or the inner housing structure  2054 , as will be discussed below, to ensure reliable connection to the power contact  1826  of the receptacle assembly  1720 . 
     The ground contact  2058  is configured substantially similar to the power contact  2056 . The ground contact  2058  is connected to a ground wire  2058   a , particularly a single conductor thereof, and is configured to physically contact and, thereby, electrically couple to the contact portion  1828   a  of the ground contact  1828  in the receptacle assembly  1720 . The ground contact  2058  includes multiple fingers  2058   b  (e.g., ground fingers) that extend generally in an axial direction from the ground wire  2058   a . For further details of the ground contact, including the multiple fingers  2058   b , refer to discussion of the power contact  2056  above. 
     As arranged in the plug assembly  1750 , the power contact  2056  is arranged radially opposite the ground contact  2058 . The power contact  2056  and the ground contact  2058 , thereby, define a recess for receiving therein and contacting the power contact  1826  and the ground contact  1828  of the receptacle assembly  1720 . In the distal and intermediate regions, the recess defined between the power contact  2056  and the ground contact  2058  may be generally cylindrical and/or frusto-conical to facilitate receipt of the power contact  1826  and the ground contact  1828  therein. 
     The data contact  2060  is connected to a data wire  2060   a  to conduct data signals therebetween and also connect shielding of the data wire  2060   a  to the shield  1824  and the enclosure  1702 . The data wire  2060   a  includes a shield (not labeled) and a dielectric (not labeled) that surround a central conductor (not labeled). The data wire  2060   a  may, for example, form or be connected to the data conductor  561  and the shielding layer  563  of the cable  160 . The data wire  2060   a  may, for example, be coax or similar. The data contact  2060  includes a shield contact portion  2060   b  and a data contact portion  2160   c  that are, respectively, electrically connected to the shield and the central conductor of the data wire  2060   a . The data contact portion  2160   c  may be seen in  FIGS. 21A-21D . The shield contact portion  2060   b  and the data contact portion  2160   c  are further configured to physically contact and, thereby, electrically couple to the shield member  1830   a  and the conductor  1830   b  of the data contact  1830  of the receptacle assembly  1720 , which thereby form a data pathway for transferring data and a shield pathway (e.g., electrically connecting or grounding the shield of the data wire  2060   a  to the enclosure  1702 ). The shield contact portion  2060   b  is, for example, received by the shield member  1830   a . The shield member  1830   a  is, thereby, electrically coupled to the shield plate  1824  and the enclosure  1702 . The data contact portion  2160   c  may, for example, receive the conductor  1830   b  of the data contact  1830  of the receptacle assembly  1720  therein. 
     The inner housing structure  2054  is mechanically connected to the power contact  2056 , the ground contact  2058 , and the data contact  2060 , so as to facilitate contact with the power contact  1826 , the ground contact  1828 , and the data contact  1830 , respectively, of the receptacle assembly  1720  when inserted therein. The inner housing structure  2054  is a generally annular member having a proximal portion  2054   a  and a distal portion  2054   b . The proximal portion  2054   a  is generally configured to couple to and/or otherwise support the power contact  2056 , the ground contact  2058 , and the data contact  2060 . The distal portion  2054   b  defines a recess  2054   c  in which the power contact  2056 , the ground contact  2058 , and the data contact  2060  are positioned, and in which the power contact  1826 , the ground contact  1828 , and the data contact  1830  of the receptacle assembly  1720  are received. 
     Furthermore, the power contact  2056 , the ground contact  2058 , and the data contact  2060  of the plug assembly  1750  may be cooperatively configured with the power contact  1826 , the ground contact  1828 , and the data contact  1830  of the receptacle assembly  1720  to facilitate electrical connections being performed in a particular order or sequence. For example, as the plug assembly  1750  is inserted into the receptacle assembly  1720 , the ground contacts  2058 ,  1828  first connect with each other, then the power contacts  2056 ,  1826  connect with each other, then the data contacts  2060 ,  1830  connect with each other. This ordered sequence of connections may be to ensure proper power sequencing and/or to prevent effects of arcing and electrostatic discharge. Conversely, when the plug assembly  1750  is removed, the data contacts  2060 ,  1830  first disconnect from each other, then the power contacts  2056 ,  1826  disconnect from each other, then the ground contacts  2058 ,  1828  disconnect from each other. Such ordered or sequenced connections may be facilitated, for example, by the respective lengths of the contacts. Referring to the schematic detail view of  FIG. 21E , for example, prior to connection (e.g., when the plug assembly  1750  is partially inserted into the receptacle assembly  1720 ), the ground contacts  2058 ,  1828  are in closer axial proximity to each other than are the power contacts  2056 ,  1826 , and the power contacts  2056 ,  1826  are in closer axial proximity to each other than the data contacts  2060 ,  1830 . 
     The proximal portion  2054   a  of the inner housing structure  2054  defines a bore through which the data wire  2060   a  and the data contact  2060  extend. The data contact  2060  is, further, supported by the proximal portion  2054   a  to be suspended in the distal portion  2054   b  for connection to the data contact  1830  of the receptacle assembly  1720 . 
     The power wire  2056   a  and the ground wire  2058   a  extend parallel with the proximal portion  2054   a  and are positioned radially opposite each other. The power wire  2056   a  and the ground wire  2058   a  may, for example, form or be coupled to the conductors  568  of the cable  160 . The power contact  2056  and the ground contact  2058  may each be connected and/or otherwise supported by the inner housing structure  2054 . The distal portion  2054   b  additionally includes apertures  2054   d  in which the fingers  2056   b  of the power contact  2056  and the fingers  2058   b  of the ground contact  2058  are arranged to engage the power contact  1826  and the ground contact  1828  when received in the recess thereof. 
     The inner housing structure  2054  is, for example, an injection molded polymer (e.g., polyamide) member, but may be made according to other manufacturing processes and/or different suitable materials. 
     The outer housing structure  2052  is a generally tubular structure (e.g., annular). The outer housing structure  2052  surrounds and contains therein the inner housing structure  2054 , as well as the power contact  2056 , the ground contact  2058 , and the data contact  2060 . The outer housing structure  2052  is configured to be inserted into the primary recess  1734   a  and releasably connect and seal to the primary housing structure  1834  of the receptacle assembly  1720 . For example, the outer housing structure  2052  may include a sprung lever  2052   a  that engages the locking feature  1834   a  of the primary housing structure  1834  of the receptacle assembly  1720 . A gasket  2064  (e.g., a polymer O-ring) may also be arranged and compressed radially between the outer housing structure  2052  of the plug assembly  1750  and the primary housing structure  1834  to form the seal therebetween. 
     The outer housing structure  2052  is, for example, an injection molded polymer (e.g., polyamide) member, but may be made according to other manufacturing processes and/or different suitable materials. 
     The wire seal  2062  is configured to support the power wire  2056   a , the ground wire  2058   a , and the data wire  2060   a  in a proximal end of the outer housing structure  2052 . The wire seal  2062  additionally forms a seal with the outer housing structure  2052  and/or the inner housing structure  2054 , as well as forms seals with the power wire  2056   a , the ground wire  2058   a , and the data wire  2060   a  extending axially therethrough. The wire seal  2062  is, for example, an injection molded elastomeric component. 
     The plug assembly  1750  may additionally include a housing cover  2066 , which is received over the distal end of the outer housing structure  2052 . The housing cover  2066  is coupled to the outer housing structure  2052  (e.g., with snap-fit arrangement) to retain the wire seal  2062  therein. 
     The plug assembly  1750  may additionally include a terminal position assurance member  2168 , which is arranged radially between the inner housing structure  2054  and the outer housing structure  2052 . The terminal assurance member  2168  is a structure, which may function to align and/or support the power contact  2056  and the ground contact  2058  in proper positions in the plug assembly  1750 .
