Description:
BACKGROUND 
     Power and data may be provided from one electronic device to another over cables that may include one or more wires, fiber optic cables, or other conductors. Connector inserts may be located at each end of these cables and may be inserted into connector receptacles in the communicating or power transferring devices. 
     These connector receptacles may be located in openings in enclosures of electronic devices. In some circumstances, it may be desirable to combine more than one connector receptacle into a single unit, which may be referred to as a combined connector receptacle. 
     Various problems may arise when connector receptacles are gathered into a combined connector receptacle. For example, it may be difficult to align multiple connector receptacles to openings in an enclosure of an electronic device. This may be particularly true when the surface of the enclosure is nonplanar. 
     Also, contacts in each connector receptacle may convey high-speed signals, power supplies, and other signals. The high-speed signals may have relatively fast edges. These fast edges may have high-frequency signal components that may degrade nearby power supplies. The high-frequency signal components from the high-speed signals and nearby power supplies may couple onto high-speed signal contacts in the same or other connector receptacle in the combined connector receptacle, thereby degrading the performance of the same or other connector receptacle. 
     Contacts in a connector receptacle may terminate in through-hole contact portions that may be inserted into corresponding openings in a board during device assembly. Including more than one connector receptacle in a combined connector receptacle may make the insertion of the through-hole contact portions more complicated. Specifically, the number of contacts and corresponding through-hole contact portions may increase, thereby making alignment of the through-hole contact portions to corresponding openings in a board more difficult. 
     Thus, what is needed are combined connector receptacles that may be aligned to openings in a device enclosure, may provide isolation between individual connector receptacles, may have reduced noise coupling to high-speed signal contacts within a connector receptacle, and may have structures arranged to reduce or eliminate damage to through-hole contact portions during their insertion into corresponding openings in a printed circuit board. 
     SUMMARY 
     Accordingly, embodiments of the present invention may provide combined connector receptacles that may be aligned to openings in a device enclosure, may provide isolation between individual connector receptacles, may have reduced noise coupling to high-speed signal contacts within a connector receptacle, and may have structures arranged to reduce or eliminate damage to through-hole contact portions during their insertion into corresponding openings in a printed circuit board. 
     An illustrative embodiment of the present invention may provide a combined connector receptacle having a housing with a number of slots. Each slot may be shielded with an electromagnetic interference (EMI) contact rail. Individual connector receptacles may be inserted into each slot. The individual connector receptacles may physically float relative to the housing of the combined connector receptacle. This floating may provide enough leeway or tolerance such that each connector receptacle may be aligned with an opening in a device enclosure. This floating may also provide protection for the connector receptacle during insertion of a connector insert. An alignment pin that may be inserted in an opening or recess of a device enclosure may also be included as part of the combined connector receptacle. 
     These and other embodiments of the present invention may provide a combined connector receptacle that may be used to provide multiple connector receptacles where a surface of the device enclosure is nonplanar. For example, a top of a housing for the combined connector receptacle may have openings that are oblique to other openings in the combined connector housing. Connector receptacle portions, such as connector receptacle tongues, may emerge from the openings at oblique angles as well. 
     These and other embodiments of the present invention may provide a combined connector receptacle having improved EMI isolation between individual connector receptacles. For example, a combined connector receptacle may include a housing having a number of slots. Each slot may be shielded using an EMI contact rail. Individual connector receptacles may be inserted into each slot. Each connector receptacle may be individually shielded. Also, each tongue of a connector receptacle may include a central ground plane to isolate contacts on a top side of a tongue from contacts on a bottom side of the tongue. The housing of the combined connector receptacle may be further shielded. The shields around the connector receptacles, the central ground plane, and the shields around the housing of the combined connector receptacle may include tabs or through-hole contact portions that may be fit in openings in a printed circuit board or other appropriate substrate where they may be connected to ground planes or traces. These several layers of shielding may provide a combined connector receptacle having improved EMI isolation between individual connector receptacles. The combined connector receptacle may be mounted on the printed circuit board or other appropriate substrate such that the tongues of the individual connector receptacles are substantially orthogonal to the printed circuit board, though they may be at least somewhat oblique to the printed circuit board due to the nonplanar nature surface of the device enclosure. In these and other embodiments of the present invention, the tongues may be located in openings in a device enclosure or portion of a device enclosure to form a complete connector receptacle with a tongue and recess. The device enclosure or portion of a device enclosure may be metallic, plastic, or other material. Openings in the device enclosure or portion of a device enclosure may include spring fingers to be electrically connected to shields of the connector receptacles. This may further improve EMI isolation between individual connector receptacles and between the combined connector receptacle and other circuits or components. 
     These and other embodiments of the present invention may provide a combined connector receptacle having improved EMI isolation within individual connector receptacles. For example, each tongue of a connector receptacle may include a central ground plane to isolate contacts on a top side of a tongue from contacts on a bottom side of the tongue. Contacts for each high-speed differential pair on a top or bottom side of the tongue may be adjacent on each lateral side to a power supply or ground contact such that a power supply or ground contact may be between nearby high-speed differential pair signal contacts. These power supply or ground contacts between high-speed differential pair signal contacts may isolate the high-speed differential pair signal contacts. 
     To further improve this isolation, these power supply or ground contacts may each be coupled to the central ground plane by decoupling capacitors. In these and other embodiments of the present invention, the decoupling capacitors may be formed using a high-dielectric constant structure. Specifically, a high-dielectric constant structure may be placed between a power supply or ground contact and the central ground plane to form a decoupling capacitor. In these and other embodiments of the present invention, other types of decoupling capacitors may be used. For example, discrete capacitors, such as ceramic, film, electrolytic, or other types of capacitors, may be used. Biasing members may be included to ensure a good electrical connection between the discrete capacitors and the power and ground contacts and central ground plane. The biasing members may be springs, they may be formed of a conductive and compressible material, or they may be other types of biasing members. These decoupling capacitors may be located in a housing of a combined connector receptacle, in a housing of an individual connector receptacle, in a tongue of a connector receptacle, or elsewhere in a combined connector receptacle. 
     These and other embodiments of the present invention may provide a combined connector receptacle having a housing with a number of slots. Each slot may be shielded with an EMI contact rail. Individual connector receptacle may be inserted into each slot. The individual connector receptacles may physically float relative to the housing of the combined connector receptacle. This floating may allow through-hole contact portions for the connector receptacles to be aligned to each other. An organizer may be fit over the through-hole contact portions for the various connector receptacles. The through-hole contact portions of the combined connector receptacle may then be inserted into a printed circuit board, such as a printed circuit board or other appropriate substrate. 
     In these and other embodiments of the present invention, the organizer may be fit against one or more connector receptacles in a combined connector receptacle unit. The through-hole contact portions of the combined connector receptacle unit may then be inserted into corresponding holes in a printed circuit board or other appropriate substrate. In other embodiments of the present invention, the organizer may be positioned away from the combined connector receptacle towards ends of the through-hole contact portions. During assembly, a combined connector receptacle unit may be placed on the printed circuit board such that an organizer contacts or is near the printed circuit board. The combined connector receptacle unit may be pushed onto the printed circuit board such that the organizer is moved towards the combined connector receptacle and the through-hole contact portions are pushed into corresponding openings in a printed circuit board or other appropriate substrate. 
     While an organizer may be used to align through-hole contact portions to corresponding openings in a printed circuit board, openings in a device enclosure or device enclosure portion may be used to align the tongues of the connector receptacles of a combined connector receptacle. The openings in an inside surface of the device enclosure or device enclosure portion may have tapered lead-ins to guide the individual connector receptacle tongues during mating of the combined connector receptacle to the openings in a device enclosure or device enclosure portion. The device enclosure or device enclosure portion may be at least partially held in place with pieces of foam or other compliant piece. This may allow the device enclosure or device enclosure portion to slightly reposition itself so that it may be easier to mate with the combined connector receptacle. Since the individual connector receptacles may physically float in the housing of the combined connector receptacle, the openings in the device enclosure or device enclosure portion may determine a final position of the tongues of the connector receptacles. 
     While embodiments of the present invention may be useful in combined connector receptacles, these and other embodiments of the present invention may be used in single connector receptacle structures as well. 
     In various embodiments of the present invention, contacts, central ground planes, shields, EMI contact rails, and other conductive portions of a combined connector receptacle may be formed by stamping, metal-injection molding, machining, micro-machining, 3-D printing, or other manufacturing process. The conductive portions may be formed of stainless steel, steel, copper, copper titanium, phosphor bronze, or other material or combination of materials. They may be plated or coated with nickel, gold, or other material. The nonconductive portions, such as the housings, tongues, organizers, and other portions may be formed using injection or other molding, 3-D printing, machining, or other manufacturing process. The nonconductive portions may be formed of silicon or silicone, rubber, hard rubber, plastic, nylon, liquid-crystal polymers (LCPs), ceramics, or other nonconductive material or combination of materials. The biasing members and high-dielectric constant structures may be formed of various materials. The printed circuit boards used may be formed of FR-4 or other material. Printed circuit boards may be replaced by other substrates, such as flexible circuit boards, in many embodiments of the present invention. 
     Embodiments of the present invention may provide combined connector receptacles that may be located in, and may connect to, various types of devices, such as portable computing devices, tablet computers, desktop computers, laptops, all-in-one computers, wearable computing devices, cell phones, smart phones, media phones, storage devices, portable media players, navigation systems, monitors, power supplies, video delivery systems, adapters, remote control devices, chargers, and other devices. These combined connector receptacles may provide pathways for signals that are compliant with various standards such as one of the Universal Serial Bus (USB) standards including USB Type-C, High-Definition Multimedia Interface® (HDMI), Digital Visual Interface (DVI), Ethernet, DisplayPort, Thunderbolt™, Lightning™, Joint Test Action Group (JTAG), test-access-port (TAP), Directed Automated Random Testing (DART), universal asynchronous receiver/transmitters (UARTs), clock signals, power signals, and other types of standard, non-standard, and proprietary interfaces and combinations thereof that have been developed, are being developed, or will be developed in the future. Other embodiments of the present invention may provide combined connector receptacles that may be used to provide a reduced set of functions for one or more of these standards. In various embodiments of the present invention, these interconnect paths provided by these connector inserts and connector receptacles may be used to convey power, ground, signals, test points, and other voltage, current, data, or other information. 
     Various embodiments of the present invention may incorporate one or more of these and the other features described herein. A better understanding of the nature and advantages of the present invention may be gained by reference to the following detailed description and the accompanying drawings.

     DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
       FIG. 1  illustrates an electronic system that may be improved by the incorporation of embodiments of the present invention. This figure, as with the other included figures, is shown for illustrative purposes and does not limit either the possible embodiments of the present invention or the claims. 
     This electronic system includes computer  110  and electronic device  130 . Computer  110  may communicate with electronic device  130  through cable  150 . Specifically, connector insert  140  may be inserted into one of the group of connector receptacles in combined connector receptacle  120  on computer  110 , and computer  110  may communicate with an electronic device  130  by sending and receiving signals and power, through conductors in cable  150 . 
     Again, it may be desirable for computer  110  to communicate with several devices. These devices may be able to communicate with computer  110  using the same interface standard. Accordingly, several connector receptacles of the same type may be provided as a combined connector receptacle  120 , though in other embodiments of the present invention, two or more connector receptacles in combined connector receptacle  120  may be different from each other. Combined connector receptacle  120  may include a number of individual connector receptacles, each having a number of contacts or pins, which may terminate in through-hole contact portions that are soldered in openings connected to traces in a printed circuit board (not shown) in computer  110 . 
     Unfortunately, when several connector receptacles are provided as a unit, it may be very difficult to align through-hole contact portions for the contacts of the connector receptacles to openings in a printed circuit board. It may also be difficult to align the connector receptacle tongues to corresponding openings in a device enclosure of computer  110 . This is particularly true if a surface of the device enclosure for computer  110  is curved at these openings. 
     Accordingly, an illustrative embodiment of the present invention may provide a combined connector receptacle having a housing with a number of slots. Each slot may be shielded with an EMI contact rail. Individual connector receptacle may be inserted into each slot. The individual connector receptacles may physically float relative to the housing of the combined connector receptacle. This floating may provide enough leeway or tolerance that each connector receptacle may be aligned with an opening in a device enclosure. This floating may also provide protection for the connector during insertion of a connector insert. An alignment pin to fit in an opening or recess of a device enclosure may also be included as part of the combined connector insert. This alignment pin may be conductive or nonconductive. An example of such a combined connector receptacle is shown in the following figures. 
       FIG. 2  illustrates combined connector receptacle  120  according to an embodiment of the present invention. Combined connector receptacle  120  may include a number of connector receptacles  200  located in slots  201  in housing  121 . Combined connector receptacle  120  may be shielded by strap  124 , shield  126 , and EMI contact rail  128 . Combined connector receptacle  120  may further include an alignment pin  123 . Alignment pin  123  may be inserted into opening or recess in device enclosure  2210  (shown in  FIG. 22 ) of a device that includes combined connector receptacle  120 . Housing  121  may include post structures  129  that may terminate in posts  122 . Posts  122  may be inserted in openings in a printed circuit board, flexible circuit board, or other appropriate substrate  510  (shown in  FIG. 22 ). 
     Tongues  210  for connector receptacles  200  may emerge from slots  201 . Tongues  210  may support a number of contacting portions  221  of contacts  220  on its top and bottom sides. Tongues  210  may further support ground contacts  230  on the top and bottom side. Contacting portions  221  of contacts  220  may mate with corresponding contacts of connector insert  2230  (shown in  FIG. 22 ) when connector insert  2230  is inserted into connector receptacle  200 . Ground contacts  230  may mate with corresponding ground contacts in connector insert  2230  when connector insert  2230  is inserted into connector receptacle  200 . Tongue  210  may further include notches  240  on its sides. These notches  240  may provide a retention force along with ground contacts (not shown) of connector insert  2230  that may engage notches  240  when connector insert  2230  is inserted into connect receptacle  200 . Side ground contact  233  may be located in notches  240  and may electrically connect to the side ground contacts of connector insert  2230 . Each connector receptacle  200  may include housing  260 , which may be at least partially surrounded by shield  250 . Contacts  220  may terminate in through-hole contact portions  222 , which may emerge from bottoms of housings  260 . Shields  250  for connector receptacles  200  may terminate in tabs  252 . Through-hole contact portions  222  and tabs  252  may be inserted into openings in a printed circuit board, flexible circuit board, or other appropriate substrate  510  (shown in  FIG. 22 ). Combined connector receptacle  120  may be mounted on printed circuit board  510 . Tongues  210  of individual connector receptacles  200  may be substantially orthogonal to printed circuit board  510 , with a possible variance due to a curvature of at top of housing  121 . The curvature of the top of housing  121  may be arranged to fit with an inside surface of device enclosure  2210  (shown in  FIG. 22 ). 
       FIG. 3  illustrates a cutaway side view of combined connector receptacle  120  according to an embodiment of the present invention. Again, housing  121  of combined connector receptacle  120  may include a number of slots  201 . Housing  121  may be shielded by strap  124 , shield  126 , and EMI contact rail  128 . Specifically, strap  124  may be located along a front center of combined connector receptacles  120 . The top sides of housing  121  may be shielded by shield  126 . The bottom sides of housing  121  may be shielded by EMI contact rail  128 . EMI contact rail  128  may fold underneath the bottom of housing  121  and extend along inside wall  202 . EMI contact rail  128  may make physical contact and an electrical connection with shield  250  around connector receptacle  200  for outer connector receptacles  200 . Shields  250  for middle connector receptacles  200  may be electrically connected to shields  250  for outer connector receptacles  200  via intermediate EMI contact rails  310 . Intermediate EMI contact rails  310  may electrically connect shields  250  for adjacent connector receptacles  200  to each other. In this way, strap  124  may be electrically connected to and in physical contact with shield  126 , which may be electrically connected to and in physical contact with EMI contact rail  128 , which may be electrically connected to and in physical contact with shields  250  of connector receptacles  200 , either directly or via intermediate EMI contact rails  310 . 
     Tongues  210  for connector receptacles  200  may emerge from slots  201 . Tongues  210  may support a number of contacting portions  221  (shown in  FIG. 2 ) of contacts  220  and ground contacts  230 . Sides of tongues  210  may include notches  240 . Side ground contacts  233  may be located in notches  240 . Side ground contacts  233  may be formed by edges of central ground plane  232 . Contacting portions  221  of contacts  220  may be located between ground contacts  230  and a front or leading edge  211  of tongue  210  on both a top and bottom side of tongue  210 . 
     Connector receptacles  200  may be held in place at least partially by dimples  262  (shown in  FIG. 8 ) on housing  260 , which may be located in openings  253  in shield  250  and corresponding openings (not shown) in either EMI contact rail  128  or intermediate EMI contact rail  310 . Alignment pin  123  may be inserted into a recess or opening in housing  121   
     Again, embodiments of the present invention are well-suited for use in devices where a device enclosure, such as device enclosure  2210  in  FIG. 22 , includes a curved surface. Accordingly, at least two of connector receptacles  200  may have tongues  210  that are at an oblique angle to each other in at least one plane. In other embodiments of the present invention, connector receptacles  200  may have tongues  210  that are parallel to each other, or their tongues  210  may be oblique or orthogonal to each other in one or more different planes. 
     While embodiments of the present invention may be useful in combined connector receptacles  120 , these and other embodiments of the present invention may be used in single connector receptacle structures. Also, while six connector receptacles  200  are shown in these examples, in these and other embodiments of the present invention, other numbers of connector receptacles  200  may be included. 
     The connector receptacle contacts  220  may have contact portions  221  on tongues  210  and may emerge from a bottom of housing  260  as through-hole contact portions  222 , though in other embodiments of the present invention, they may emerge as surface-mount contact portions. Shields  250  for connector receptacles  200  may terminate in tabs  252 . Through-hole contact portions  222  and tabs  252  may be inserted into openings in printed circuit board  510  (shown in  FIG. 22 ). Housing  121  may be attached to post structures  129  that may terminate in posts  122 . Posts  122  may also be inserted in openings in printed circuit board  510 . 
     It may be difficult to align these through-hole contact portions  222 , tabs  252 , and posts  122  in their corresponding holes in printed circuit board  510  in  FIG. 22 . This may lead to one or more of the through-hole contact portions  222  or tabs  252  being “crushed” and otherwise destroyed or damaged when combined connector receptacle  120  is mated to printed circuit board  510 . 
     Accordingly, embodiments of the present invention may employ an organizer  300 . Organizer  300  may include openings for some or all of the through-hole contact portions  222 , tabs  252 , and posts  122 . Organizer  300  may keep these structures aligned when combined connector receptacle  120  is mated with a printed circuit board, such as printed circuit board  510  in  FIG. 22 . An example of such an organizer is shown in the following figure. 
       FIG. 4  illustrates an exploded view of combined connector receptacle  120  according to an embodiment of the present invention. Combined connector receptacle  120  may include housing  121 , a plurality of connector receptacles  200 , and organizer  300 . Housing  121  may include a plurality of slots  201 . EMI contact rails  128  and intermediate EMI contact rails  310  (shown in  FIG. 3 ) may be inserted along sides of housing  121  and in slots  201 . Strap  124  may be placed along a center of top surface of housing  121 . Alignment pin  123  may be inserted into a recess or opening in housing  121 . Shield  126  may be placed around the top sides of housing  121  such that it is in physical and electrical contact with strap  124  and EMI contact rails  128 . Post structures  129  including posts  122  may be attached to housing  121 . 
     Connector receptacles  200  may be inserted into slots  201  in housing  121 . Connector receptacles  200  may be inserted between EMI contact rails  128  and intermediate EMI contact rails  310  in slots  201  until dimple  262  is aligned with openings (not shown) in EMI contact rails  128  and intermediate EMI contact rails  310 . Tongues  210  may support contacts  220  and ground contacts  230 . Tongues  210  may include notches  240  in their sides. Contacts  220  may terminate in through-hole contact portions  222 . Shields  250  (shown in  FIG. 3 ) around connector receptacles  200  may terminate in tabs  252 . 
     Organizer  300  may include raised portions  320  and  322 . Raised portions  320  and  322  may help secure organizer  300  in place along a bottom of combined connector receptacle  120 . Tabs  252  may fit into openings  340 , while through-hole contact portions  222  may fit in openings  330  of organizer  300 . Posts  122  may be inserted through openings  350  in organizer  300 . Organizer  300  may prevent “pin crush” from occurring with through-hole contact portions  222  or tabs  252  as the combined connector receptacle  120  is inserted into printed circuit board  510  (shown in  FIG. 22 ). A method of such an insertion is shown in the following figures. 
     In various embodiments of the present invention, organizer  300  may be installed flush to a bottom surface of a combined connector receptacle  120 . In other embodiments of the present invention, organizer  300  may be installed a distance away from the bottom surface of the combined connector receptacle  120 . In this embodiment, as the combined connector receptacle  120  is installed, printed circuit board  510  may push the organizer such that it is, or is nearly flush with the bottom side of the combined connector receptacle  120  after insertion. An example is shown in the following figure. 
       FIGS. 5-7  illustrate an installation of combined connector receptacle  120  including organizer  300  according to an embodiment of the present invention.  FIG. 5  shows an initial state where organizer  300  may be installed a distance away from a bottom side of housing  121  of combined connector receptacle  120 . Through-hole contact portions  222 , tabs  252 , and posts  122  may be aligned with openings (not shown) in printed circuit board  510 , where printed circuit board  510  may be a flexible circuit board or other appropriate substrate. In  FIG. 6 , the combined connector receptacle  120  is shown in the process of being inserted into printed circuit board  510 . In this position, organizer  300  may be offset from a bottom of housing  121 .  FIG. 7  shows a final state, where the combined connector receptacle  120  may be inserted into printed circuit board  510 . In this final state, organizer  300  may be flush with a bottom of combined connector receptacle  120  and a top surface of printed circuit board  510 . In other embodiments of the present invention, organizer  300  may be flush, or nearly flush, with an underside of the combined connector receptacle  120  before the combined connector receptacle  120  is mated with printed circuit board  510 . In these and other embodiments of the present invention, organizer  300  may be formed of various materials. For example, organizer may be nonconductive and may be formed of plastic, fibers, fiberglass, or other material. 
       FIG. 8  illustrates connector receptacle  200  according to an embodiment of the present invention. Connector receptacle  200  may include tongue  210 . Tongue  210  may support a number of contacts  220  and ground contacts  230  on a top and a bottom side. Tongue  210  may further include notches  240 . Side ground contacts  233  may be located in notches  240 . Connector receptacle  200  may be covered by shield  250 . Shield  250  may include openings  253  for dimples  262 . Shield  250  may terminate in tabs  252 . Contacts  220  may include contacting portions  221  and may terminate in through-hole contact portions  222 . Shield  250  may be partially covered by over-shield portion  810 . 
     While connector receptacle  200  shown herein may be useful in combined connector receptacles  120 , these and other embodiments of the present invention may be used in single connector receptacle structures where only one connector receptacle  200  is included. Also, while six connector receptacles  200  are shown in the above examples, in these and other embodiments of the present invention, other numbers of connector receptacles  200  may be included. 
     Signals conveyed by contacts  220  in connector receptacle  200  may be shielded by adjacent contacts and a central ground plane. This may help to prevent signal components of a signal conveyed in a connector receptacle  200  from corrupting a second signal in the same or different connector receptacle  200 . An example is shown in the following figure. 
       FIG. 9  illustrates a transparent view of connector receptacle  200  according to an embodiment of the present invention. Connector receptacle  200  may include contacts  920  for conveying a differential signal pair. These differential signal contacts  920  may be adjacent to power supply contact  910  and ground contact  930 . These various contacts may pass through housing  260 . The differential signal contacts  920  may terminate in through-hole contact portions  922 , the power supply contact  910  may terminate in through-hole contact portion  912 , and ground contact  930  may terminate in through-hole contact portion  932 . 
     A central ground plane  232  may extend through the middle of housing  260 . Housing  260  may be formed of a top housing portion  268  and a bottom housing portion  269 . Central ground plane  232  may terminate in through-hole contact portions  239 . In this way, through-hole contact portions  922  for signal contacts  920  may be surrounded by through-hole contact portion  912  for power, through-hole contact portion  932  for ground, and through-hole contact portions  239  for the central ground plane  232 . This may provide EMI isolation for the differential signal conveyed on contacts  920 , thereby reducing coupling to those contacts and preventing the signals on those contacts from coupling elsewhere in a combined connector receptacle and an electronic device that houses the combined connector receptacle. 
       FIG. 10  illustrates a side view of connector receptacle  200  according to an embodiment of the present invention. Again, central ground plane  232  may run between top housing portion  268  and bottom portion  269 . Central ground plane  232  may terminate in through-hole contact portions  239 . Through-hole contact portions  922  for the differential signal contact may be located between through-hole contact portions  912  and  932  for power supply and ground and through-hole contact portions  239  for central ground plane  232 . 
     Again, differential signals conveyed on contacts  920  (shown in  FIG. 9 ) may be at least partially surrounded by power supply contact  910 , ground contact  930  (both shown in  FIG. 9 ), and central ground plane  232 . Unfortunately, energy may be stored between the differential pair signal on contacts  920  and the power supply contact  910  and ground contact  930 . This stored energy may be reflected between printed circuit board  510  (shown in  FIG. 22 ) on which connector receptacle  200  is mounted and connector insert  2230  (shown in  FIG. 22 ) that may be mated with connector receptacle  200 . These reflections may create insertion loses that may increase with frequency. An example is shown in the following figure. 
       FIG. 11  illustrates a simplified cross-section of connector receptacle  200  according to an embodiment of the present invention. This cross-section may be taken along line A-A′, as shown in  FIG. 10 . Again, contacts  920  for a differential signal may be surrounded by power supply contact  910  and ground contact  930 , and may be located over central ground plane  232 . The energy stored between differential signal contacts  920  and power supply contact  910  or differential signal contacts  920  and ground contact  930  may be reflected between a printed circuit board  510  (shown in  FIG. 22 ) on which connector receptacle  200  is mounted and connector insert  2230  (shown in  FIG. 22 ) that is mated with connector receptacle  200 . These reflections may lead to a resonance effect. This stored energy and resulting reflections, or resonance effect, may result in an insertion loss that may increase with frequency. Accordingly, embodiments of the present invention may employ components or circuits to reduce the impedance of power supply contact  910  and ground contact  930 . An example is shown in the following figure. 
       FIG. 12  illustrates a cross-section of connector receptacle  200  according to an embodiment of the present invention. In this example, decoupling capacitor  1210  has been connected between power supply contact  910  and central ground plane  232 . Similarly, decoupling capacitor  1220  has been connected between ground contact  930  and central ground plane  232 . Decoupling capacitors  1210  and  1220  may reduce the energy stored between the differential signal contacts  920  and power supply contact  910  and differential signal contacts  920  and ground contact  930  at high frequency. This may reduce or eliminate the reflections or resonance effect, thereby reducing resulting insertion losses for the differential signal. In various embodiments of the present invention, various types of capacitor structures may be used as decoupling capacitors  1210  and  1220 . For example, high-dielectric constant structures may be located between power supply contact  910  and central ground plane  232  and between ground contact  930  and central ground plane  232 . In these and other embodiments of the present invention, other types of capacitor structures, such as discrete capacitors, may be used. These decoupling capacitors  1210  and  1220  may be located in a housing of a combined connector receptacle, in a housing of an individual connector receptacle, in a tongue of a connector receptacle, or elsewhere in a combined connector receptacle. Examples are shown in the following figures. 
       FIG. 13  illustrates a transparent view of connector receptacle  200  according to an embodiment of the present invention. In this example, power supply contact  910  may include a widened region  913 . High-dielectric constant structure  1310  may be located between widened region  913  and central ground plane  232  to form decoupling capacitor  1210  (shown in  FIG. 12 ). Similarly, ground contact  930  may include widened region  933 . High-dielectric constant structure  1320  may be located between widened region  933  and central ground plane  232  to form decoupling capacitor  1220  (shown in  FIG. 12 ). These decoupling capacitors  1210  and  1220  may reduce energy stored between power supply contact  910  and differential signal contacts  920 , and between differential signal contacts  920  and ground contact  930 . This reduced store energy may reduce or eliminate reflections or resonance effect and the insertion loss for the differential signal on contacts  920 . 
     While high-dielectric constant structure  1310  and high-dielectric constant structure  1320  are shown as being formed in a housing of a connector receptacle, in other embodiments of the present invention, high-dielectric constant structure  1310  and high-dielectric constant structure  1320  may be located elsewhere in a combined connector receptacle or individual connector receptacle, such as in tongue  210 . In these and other embodiments of the present invention, tongue  210  may be formed of a printed circuit board. High-dielectric constant structure  1310  and high-dielectric constant structure  1320  may be located in or on layers (not shown) of a printed circuit board forming tongue  210 . 
       FIG. 14  illustrates a cutaway side view of connector receptacle  200  according to an embodiment of the present invention. High-dielectric constant structures  1310  and  1320  may be located in housing  1260 . High-dielectric constant structure  1310  may be located between central ground plane  232  and widened portion  913  of power supply contact  910  as shown in  FIG. 13  to form decoupling capacitor  1210  (shown in  FIG. 12 ). Similarly, high-dielectric constant structure  1320  may be located between central ground plane  232  and widened portion  933  of ground contact  930  as shown in  FIG. 13  to form decoupling capacitor  1220  (shown in  FIG. 12 .) Signal contacts  920  may be located between the widened portion  913  of power supply contact  910  and widened portion  933  of ground contact  930 . Signal contacts  920  may convey a differential signal pair. 
     Again, in other embodiments of the present invention, other capacitor structures may be used as decoupling capacitors  1210  and  1220 . For example, discrete capacitors, such as ceramic, film, electrolytic, or other types of capacitors may be used. One or more biasing elements, such as springs, compressible conductive foams, or other materials may be used to electrically connect a capacitor between a power contact and a central ground plane and a ground contact and the central ground plane. An example is shown in the following figure. 
       FIG. 15  illustrates a transparent view of connector receptacle  200  according to an embodiment of the present invention. In this example, discrete capacitors  1510  (which may be used for capacitors  1210  and  1220  in  FIG. 12 ) and corresponding biasing members  1520  may be placed in series between power supply contact  910  and central ground plane  232  and ground contact  930  and central ground plane  232 . Again, the biasing member  1520  may be a spring, compressible conductive foam, or other structure. 
     While capacitors  1510  and biasing members  1520  are shown as being located in a housing of a connector receptacle, in other embodiments of the present invention, capacitors  1510  and biasing members  1520  may be located elsewhere in a combined connector receptacle or individual connector receptacle, such as in tongue  210 . In these and other embodiments of the present invention, tongue  210  may be formed of a printed circuit board. Capacitors  1510  and biasing members  1520  may be located in or on layers (not shown) of a printed circuit board forming tongue  210 . 
       FIG. 16  illustrates a cutaway side view of connector receptacle  200  according to an embodiment of the present invention. In this example, capacitor  1510  may be adjacent to power supply contact  910 . Biasing member  1520  may be located between capacitor  1510  and central ground plane  232 . Biasing member  1520  may be formed of a spring, compressible conductive foam, or other structure. The same structure may be replicated for ground contact  930  as shown in  FIG. 15 . In these and other embodiments of the present invention, the positions of capacitor  1510  and biasing member  1520  may be reversed, though capacitor  1510  and biasing member  1520  may remain in series between power supply contact  910  or ground contact  930  and central ground plane  232 . 
       FIGS. 17-21  illustrates a method of assembling connector receptacle  200  according to an embodiment of the present invention. In  FIG. 17 , central ground plane  232  may be formed by stamping, printing, or other process.

A ground contact portion including ground contact  230  and ground tab  1710  may be formed, again by stamping or other procedure. The ground contact portion including ground contact  230  may be attached to central ground plane  232 . This may be done by spot or laser welding, or other procedure. Tongue  210  may be injection molded or otherwise formed around top portions of central ground plane  232 . 
     In  FIG. 18 , contacts  220  may be formed. Carrier  1810  and subcarrier  1820  may be used to manipulate contacts  220  during later processing steps. Housing  260  may be formed around portions of contacts  220 . Housing  260  may be formed by injection molding or other processing procedure. High-dielectric constant structures  1310  and  1320  may be attached to contacts  220  after housing  260  is injection molded. 
     In  FIG. 19 , shield  250  may be placed around housing  260 . Dimples  262  may emerge through openings  253  in shield  250 . 
     In  FIG. 20 , an over-shield portion  810  may be fit over shield  250 . Tabs  2014  and  2016  may be inserted into openings  2015  and  2017  in shield  250 .

Shield portion  1910  of shield  250  may be spot or laser welded at points  1912  to ground tab  1710 . 
     In  FIG. 21 , over-shield portion  810  may be spot or laser welded at points  2110  to shield  250 , thereby resulting in a completed connector receptacle  200 .
