     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to electrical or electronic components and particularly in one exemplary aspect to apparatus and methods to prevent insertion of improper modular type plugs into corresponding jacks. 
     2. Description of Related Technology 
     Modular jack connectors, such as for example those of the “RJ” configuration, are well known in the electronics industry. Such modular jack connectors are adapted to receive one or more modular plugs of varying type (e.g., RJ-45 or RJ-11), and communicate signals between the terminals of the modular plug and the parent device with which the modular jack connector is associated. Commonly, some form of signal conditioning (e.g., filtering, voltage transformation, or the like) is performed by the connector on the signals passing through it or by electronic components adjacent to the connector. 
     In telecommunications data and voice applications, there are modular jacks and plugs which contain differing numbers of poles or contacts (e.g. 4, 6, 8, etc.). Typically, the pitch between the terminals are the same for a plurality of different connector types so that, for example, a six-pole type modular plug can be plugged by mistake into an eight-pole type modular jack, which can cause electrical and/or mechanical malfunction. 
     This problem has been addressed in a myriad of prior art solutions, including for example U.S. Pat. No. 5,755,821 to Ngai, et al. issued May 26, 1998 and entitled “Device for preventing the erroneous connection of signal lines to a computer network hub” discloses either of a pair of adjacent plug holes in a computer network hub that is automatically closed by a swinging door plate whenever a connector of a signal line is inserted into the other plug hole to prevent the simultaneous insertion of two connectors into both plug holes. 
     U.S. Pat. No. 6,186,835 to Cheshire issued Feb. 13, 2001 and entitled “Socket connector having a flexible internal barrier to prevent incorrect insertion of smaller sized plugs” that discloses a socket connector that has flexible interior barriers to prevent incorrect insertion of smaller sized plugs, where a flexible internal barrier is formed on a side of the socket entry leading into the socket cavity, and is composed of a flexible ramp attached from the socket entry, the ramp extending into the socket cavity and having a inner movable end with a vertical barrier, sized and disposed within the socket cavity so that the insertion of a correctly sized wide plug will engage the flexible ramp, riding along and moving the flexible ramp so that the vertical barrier is moved out of a stopping position, allowing the correctly sized wide plug to be fully and properly seated in the cavity, but further sized and disposed within the socket cavity so that the insertion of an incorrectly sized narrow plug will fail to engage the ramp, will not flex the ramp, and will leave the vertical barrier in the stopping position, where it prevents the incorrectly sized narrow plug from being fully inserted into the socket cavity. The improved socket can be an RJ45 network socket, the correctly sized wide plug can be an RJ45 network plug, and the incorrectly sized narrow plug can be an RJ11 telephone plug. 
     U.S. Pat. No. 6,296,528 to Roberts, et al. issued Oct. 2, 2001 and entitled “Jack with feature for selectively restricting plug insertion” discloses a modular jack that includes a rectangular dielectric receptacle housing having a front face, a bottom board mounting wall, and a top, rear and a pair of side walls substantially surrounding a plug-receiving cavity. The cavity extends rearwardly from the front face for receiving a mating plug connector. In order to limit insertion of an undersized plug into a full-sized plug-receiving cavity in the receptacle housing, a stop surface is incorporated into a flexible stop member projecting from the housing and extending into the plug-receiving cavity. The stop surface is located within the cavity so as to ensure contact with a leading edge of an undersized plug upon insertion of the undersized plug into the cavity. A sliding surface is also incorporated into the flexible member. The sliding surface is located within the cavity so as to ensure contact with a leading edge of a plug upon insertion into the cavity of a mating plug having a width appropriate for mating with the jack. The sliding surface resides closer to the front face of the receptacle housing than does the stop surface. When an undersized plug is inserted into the cavity, the leading edge of the undersized plug contacts the stop surface, preventing full insertion of the undersized plug into the cavity. When a mating plug is inserted into the cavity, the leading edge of the mating plug contacts the more forwardly-positioned sliding surface before reaching the stop surface. Sliding contact between the sliding surface and the mating plug leading edge causes the sliding surface to move. This movement produces a corresponding movement in the flexible stop member and the stop surface incorporated thereon such that the stop surface is located out of engagement with the leading surface of the mating plug, permitting full insertion of the mating plug into the cavity. 
     U.S. Pat. No. 6,350,156 to Hasircoglu, et al. issued Feb. 26, 2002 and entitled “Modular jack with deflectable plug-blocking member” discloses a modular jack for receiving an RJ-45 plug and for blocking insertion of an RJ-11 plug. The modular jack has stamped and formed deflection members having retention sections, ramp surfaces and blocking tabs extending from ends of the ramp surfaces. The blocking tabs project laterally inwardly toward the plug-receiving cavity and block an RJ-11 plug from being inserted into the modular jack. An RJ-45 plug is wider than the RJ-11 plug and engages the ramp surfaces of the deflection members to deflect the blocking tabs away from the plug-receiving cavity, thereby allowing insertion of the RJ-45 plug. 
     U.S. Pat. No. 6,987,852 to Kameya, et al. which discloses a modular jack that comprises a housing and a mechanism consisting of a pair of spring members cantilevered to the housing. The modular jack further comprises an abutment section provided at the front end of each spring member. Each abutment section consists of a cam portion having an inclined face and a stopper portion provided behind and inside the cam portion. When a modular plug having a predetermined number of poles is inserted into the modular jack, the front ends of the modular plug abut the inclined faces of the cam portions to move the abutment sections outwardly, permitting insertion of the modular plug. When a modular plug having a number of poles that is smaller than the predetermined number is inserted, the front ends of the modular plug abut against the stopper portions to block insertion of the modular plug. Numerous other solutions of varying design exist. 
     U.S. Pat. No. 7,086,879 to Higham, et al. issued Aug. 8, 2006 and entitled “Dual connector assembly with sliding keep-out member” discloses a connector assembly that includes first and second sockets disposed on opposite sides of a housing and defining first and second insertion paths, respectively, for receiving a plug. A sliding keep-out member has first and second blocking surfaces. The keep-out member can move back and forth through the housing between first and second positions. In the first position, the first blocking surface blocks at least a portion of the first insertion path, but the second blocking surface clears the second insertion path. In the second position, the second blocking surface blocks at least a portion of the second insertion path, but the first blocking surface clears the first insertion path. Thus the connector assembly may receive plugs in either the first or the second socket, but not in both sockets simultaneously. 
     U.S. Pat. No. 7,264,489 to Higham, et al. issued Sep. 4, 2007 and entitled “Dual connector assembly with pivoting keep-out member” discloses a connector assembly for an electronic device that saves space and cost. It includes first and second sockets defining first and second insertion paths for receiving mating plugs. A pivoting keep-out member has first and second blocking surfaces and can be pivoted between first and second positions. In the first position, the first blocking member blocks at least a portion of the first insertion path, but the second blocking member clears the second insertion path. In the second position, the second blocking member blocks at least a portion of the second insertion path, but the first blocking member clears the first insertion path. Thus the connector assembly may receive a plug in either the first or the second socket, but not in both simultaneously. 
     United States Patent Publication No. 20030157843 to Thomas published Aug. 21, 2003 and entitled “Stacking connector with improper plug type prevention” discloses a stacked connector for use on a printed circuit board of a computer, for conserving connection space by providing two or more connector sockets, preferably oriented one atop the other. One or more of the connector sockets may be configured to prevent the insertion of an improper plug type having a similar form factor which is capable of being inserted into one of the sockets. 
     However, these prior art configurations, while effective for their designed task, are not optimized in terms of inter alia, cost and manufacturing simplicity. Accordingly, it would be desirable to provide an improved electrical connector design that would yield a simple and reliable connector that facilitates economical fabrication. Such a connector design would ideally allow for the use of anything ranging from no internal electronic components to a variety of different electronic signal conditioning components in the connector signal path(s), as well as status indicators if desired, without affecting connector profile or footprint, or requiring appreciable changes to the housing. The improved connector design would also facilitate easy assembly, as well as removal of the internal components of the device if required. The design would further be amenable to integration into a multi-port connector assembly, including the ability to vary the configuration of the internal components associated with each port of the assembly individually.

     It is noted that while the following description is cast primarily in terms of one or a plurality of RJ-type jacks and associated modular plugs of the type well known in the art, the present invention may be used in conjunction with any number of different connector types. Accordingly, the following discussion of the RJ-type jacks and plugs is merely exemplary of the broader concepts. 
     Single Port Embodiment 
     Referring now to  FIG. 1A , a first embodiment of a modular jack  100  incorporating integrated keep-out features  114  is shown and described in detail. The modular jack  100  shown in  FIG. 1A  is intended to be generalized and may readily be incorporated into any number of connectors including modular connector designs. Advantageously, the improved keep-out apparatus of the invention is largely agnostic to the underlying connector or jack architecture. 
     Referring back to  FIG. 1A , the modular jack connector  100  advantageously comprises a housing  102  made of an insulating material such as an injection-moldable polymer material. Injection-moldable polymers are desirable because of their extensive use in the electronics industry and their low cost. The housing  102  of the modular jack connector  100  generally comprises side walls  104 , a front wall  108 , a rear wall  109 , and top and bottom walls  106  and may take on any number of shapes (such as those disclosed in the above U.S. Patents incorporated by reference herein). The port  110  shown in  FIG. 1A  is a tab  112  down configuration, although it is recognized that a tab-up configuration (i.e. where tab  112  is positioned adjacent to top wall  106 ) may be readily adapted to the modular jack  100  shown in  FIG. 1A  given the present disclosure provided herein. 
     The modular jack connector  100  of the present embodiment incorporates two keep-out features  114  integrated into the housing  102  of the modular jack  100 . Each keep-out feature  114  is integrally molded into the side wall  104  of the housing  102  and comprises a first cantilever arm section  116  which projects generally parallel to the plug insertion direction for a portion of its run, and then downward (i.e., transverse to plug insertion) for a second portion of its run. The first cantilever arm section  116  extends from the side wall  104  of the housing  102  via filleted joints which serve to strengthen the interface between the side wall  104  and its respective keep-out feature  114 . Radial section  118  of keep-out feature  114  transitions the first cantilever arm section  116  into a second cantilever arm section  120  which runs in a direction generally parallel to the modular plug insertion direction and generally perpendicular to the direction of the first cantilever arm section  116 , although these angular relationships need not be observed in all applications. The length of the first and second cantilever sections  116 ,  120  respectively are governed largely by the mechanical properties of the housing material chosen and the size constraints of the modular jack connector  100  design, the design of which being well within the capability of one of ordinary skill given the present disclosure. 
     It will also be appreciated that the exemplary disposition of the feature  114  substantially within the plane of the sidewall as shown in  FIG. 1A  allows for some degree of space conservation; i.e., volume that would otherwise be consumed by the sidewall is instead allocated to portions of the feature  114 , thereby economizing on space (such as to e.g., allow for more components to disposed within the interior volume of the connector housing, or increase inter-component distances such as for improved cross-talk or EMI performance), and overall connector size if desired. 
     Referring now to  FIG. 1B , a reversed front perspective view of the modular jack connector  100  of  FIG. 1A  illustrates perhaps the best view for discussing the operation of each of the keep-out features  114 . The keep-out head section  122  of the keep-out feature  114  resides at the distal end of the second cantilever arm section  120 . The exemplary head section  122  comprises a ramp section  124  and a stop portion  126  immediately adjacent to the ramp section and is largely responsible for ensuring that an improper plug does not get inserted into the modular jack port  110 . For example, the embodiment of  FIG. 1B  is sized to accept insertion of an 8-position modular plug (e.g. an RJ-45 plug), while rejecting other types of modular plugs such as an RJ-11 modular plug. 
     If an improper plug, such as the aforementioned RJ-11 plug, is inserted into the modular jack cavity  110 , the stop portions  126  of the keep-out feature  114  will prevent the plug from being inserted far enough to make electrical contact with the contactors (not shown for clarity) present within the modular jack  100 . However, if an appropriate plug (such as an RJ-45 plug) is inserted, the front face of the plug will engage the ramp portions  124  of the keep-out features  114  and displace the head section  122  of the keep-out feature out of the way, thereby clearing the cavity  110  for insertion of the modular plug. 
     Another salient advantage of the present embodiment over prior art attempts at mitigating improper plug insertion is that the keep-out feature  114  may be integrally molded (via injection molding processes and the like) so that the additive cost of including a keep-out feature within the modular jack is minimized. Therefore this desirable feature can be included with little or no cost to the manufacture of the modular jack connector providing a distinct competitive advantage over many prior art solutions. In addition, as manual assembly processes are avoided, part to part consistency is also maximized as standard quality control procedures can ensure consistent production of the modular jacks over the life of the tooling for the modular jack. 
     Yet another important feature of the embodiment of  FIG. 1A  is the comparatively long length of the feature  114  (i.e., measured from the point of the cantilever  116  where it is formed to the housing, to the distal end (head section  122 ). From a mechanical and materials standpoint, this greater length (as compared to prior art solutions) allows for less stress on the material of the feature and housing. As an illustration, a similar feature having an effective length of a meter (1 m), if feasible, would place very little stress on the attachment point to the housing and the materials of the feature itself for a given amount of head portion deflection. Conversely, a feature having an effective length of 10 mm would encounter very significant (fatigue) stress for the same required deflection of the head portion  122 . Stated simply, by being longer, the illustrated feature  114  is likely to last longer than comparable prior art solutions given the same number of cycles, since its stresses are lower. 
     Another key feature or distinction is the fact that the embodiment of  FIGS. 1A and 1B  (and even other embodiments disclosed herein) use a feature which is both disposed substantially within the plane of the connector sidewall, and not coupled or originated at the back wall  109  of the device. 
     Referring now to  FIG. 2A , a second embodiment of a modular jack connector  200  incorporating integrated keep-out features  214  is shown and described in detail. The modular jack  200  shown in  FIG. 2A  is intended to be generalized and may readily be incorporated into any number of modular connector designs, such as e.g., those incorporated by reference previously herein. 
     Similar to  FIGS. 1A and 1B , the modular jack connector  200  of  FIG. 2A  comprises a housing  202  made of an insulating material. The housing  202  is defined by side walls  204 , front wall  208  and top and bottom walls  206  and may take on any number of geometric shapes such as those disclosed in the aforementioned U.S. Patents previously incorporated herein by reference. The port  210  shown is a tab down  212  configuration, although it is recognized that a tab up configuration (i.e. where tab  212  is positioned adjacent to top wall  206 ) may be readily adapted to the modular jack connector  200  shown in  FIG. 2A . 
     The modular jack connector  200  of the second embodiment incorporates two keep-out features  214  into the housing  202  of the modular jack connector  200 . The keep-out feature  214  is integrally molded into the side wall  204  of the housing  202  and projects in a direction generally parallel to the plug insertion direction. The first cantilever arm section  216  extends towards the front face  208  of the modular jack  200  via filleted joints which serve to strengthen the interface between the side wall  204  and the keep-out feature  214 . The length of the first cantilever section  216  is governed largely by the mechanical properties of the housing material chosen, the design of which being well within the capability of one of ordinary skill given the present disclosure. Comparing the present embodiment with that shown in  FIG. 1A , the keep-out feature  214  of the present modular jack  200  possesses a length shorter then the keep-out feature  114  of  FIG. 1A  and hence the material chosen for modular jack  200  may require properties which differ from those chosen in the modular jack  100  of  FIG. 1A . However, this may not be necessary if for instance the size of features located on the head section  222  of the keep-out feature  214  are resized appropriately (i.e. to change the amount of deflection required to move the keep-out feature  214  out of cavity  210 ). 
     Referring now to  FIG. 2B , the operation of the keep-out feature  214  is shown and described in detail and operates in a manner similar to those embodiments shown in  FIGS. 1A and 1B . The keep-out head section  222  resides at the distal end of the cantilever arm section  216 . The head section  222  comprises a ramp section  224  and a stop portion  226  and ensures that an improper plug does not get inserted into the modular jack port  210 . 
     If an improper plug, such as for example the aforementioned RJ-11 plug, is inserted into the modular jack port  210 , the stop portions  226  of the keep-out feature  214  will prevent the plug from being inserted far enough to make electrical contact with the contactors present within the modular jack connector  200 . However, if an appropriate plug (such as an RJ-45 plug) is inserted, the front face of the plug will engage the ramp portions  224  of the keep-out features  214  and displace the head section  222  of the keep-out feature out of the way, thereby clearing the cavity  210  for insertion of the modular plug. 
     Referring now to  FIG. 3A , yet another embodiment of a modular jack connector  300  incorporating integrated keep-out feature  314  functionality is shown and described in detail. The modular jack  300  shown in  FIG. 3A  is intended to be generalized and may readily be incorporated into any number of modular connector designs such as those shown in any of the aforementioned U.S. Patents previously incorporated herein. 
     The modular jack connector  300  of  FIG. 3A  comprises a housing  302  made of an insulating material such as a thermoset or thermoplastic polymer material ubiquitous in the electronic connector arts. The housing  302  is again generally defined by its side walls  304 , front wall  308  and top and bottom walls  306  although it is recognized that the housing may take any number of geometric shapes consistent with those U.S. Patents previously incorporated herein by reference. 
     The modular jack connector  300  of the third embodiment incorporates two keep-out features  314  integrally molded into the insulative housing  302  of the modular jack connector  300 . The keep-out feature  314  is advantageously integrally molded within the side wall  304  of the housing  302  and projects first in a direction generally parallel to the plug insertion direction. The first cantilever arm section  330  extends away from the front face  308  of the modular jack  300  via filleted joints which serve to strengthen the interface between the side wall  304  and the respective keep-out feature  314 . The first cantilever arm section  330  then transitions into a vertically extending section  316  followed by a third cantilever arm section  320  via radial sections  318 . The first and third cantilever arm sections  330 ,  320  run generally parallel to one another in the present embodiment, however the design is not so limited and any number of geometries (parallel or otherwise) may readily be incorporated by one of ordinary skill given the present disclosure. 
     Referring now to  FIG. 3B , the operation of the keep-out feature  314  is shown and described in detail and operates in a manner similar to those embodiments shown in  FIGS. 1B and 2B . The keep-out head section  322  resides at the distal end of the cantilever arm section  320 . The head section  322  comprises a ramp section  324  and a stop portion  326  and ensures that an improper plug does not get inserted into the modular jack cavity  310 . 
     If an improper plug (i.e. a plug smaller then the correctly sized plug) is inserted into the modular jack cavity  310 , the stop portions  326  of the keep-out feature  314  will prevent the plug from being inserted far enough to make electrical contact with the contactors present within the modular jack  300 . However, if an appropriate plug (such as an eight-position plug) is inserted, the front face of the plug will engage the ramp portions  324  of the keep-out features  314  and displace the head section  322  of the keep-out feature out of the way, thereby clearing the cavity  310  for insertion of the modular plug. 
     As will be recognized via inspection, the embodiment of  FIGS. 3A and 3B  has a feature with an effective length (and length of its arcuate section) even longer than that of the embodiment of  FIGS. 1A and 1B . This provides the benefits previously described with respect to the embodiment of  FIGS. 1A and 1B , but to an even greater degree. 
     Referring now to  FIG. 4A , a fourth embodiment of a modular jack connector  400  incorporating a single keep-out feature  414  is shown and described in detail. The modular jack connector  400  shown in  FIG. 4A  is (similar to previous embodiments disclosed) is intended to be generalized and may readily be incorporated into any number of modular connector designs such as those shown in any of the aforementioned U.S. Patents previously incorporated herein. Similar to the previous embodiments, the modular jack connector  400  comprises a housing  402  made of an insulating material and is generally defined by side walls  404 , front wall  408  and top and bottom walls  406 . 
     The keep-out feature  414  of  FIG. 4A  may either be integrally molded into the housing  402  or comprise a distinct (i.e., separately formed) element or feature as is currently shown. The keep-out feature  414  may comprise an insulating material similar to that utilized in the housing  402 , alternatively may be made from a metallic or alloy material such as a metal stamping as is shown in the illustrated embodiment, or yet other materials (e.g., non-metallic such as a different type of polymer than that used for the housing, a composite, etc.). The keep-out feature  414  of  FIG. 4A  first extends vertically along the side wall  404  and then along the top wall  406  as perhaps is best shown in the sectional view of  FIG. 4C . 
     Referring now to  FIG. 4B , the ramp  424  and stop  426  portions of the keep-out feature  414  are shown and described in detail. Unlike the embodiments shown in  FIGS. 1A-3B , the ramp  424  and stop  426  portions of the keep-out feature  414  of  FIG. 4B  are not immediately adjacent to one another. Rather, the stop portion  426  resides towards the center line of the modular jack connector  400 , although the design is in no way so limited. The ramp feature  424  of the keep-out feature  414  (here, a somewhat rounded and angled surface projecting into the port) resides towards the edge of the modular jack port  410  so that it may only be engaged by a modular plug of a proper type. The use of a substantially rounded or curved cross-section feature  424  allows the contacting portion of the inserted plug to push the feature  424  upward, while also permitting the plug to move further in the longitudinal direction without binding. Other shapes may readily be used as well, however, the shape also to some degree being determined by its placement within the plug-receiving cavity. For example, in one alternate variant, an angled or rotated “ramp” is used in place of the substantially rounded shape previously described. 
     The operation of the modular jack  400  of  FIG. 4A  is perhaps best shown at  FIGS. 4D and 4E .  FIG. 4D  demonstrates the state of the keep-out feature  414  should an improper modular plug be inserted. Because the improper modular plug is not shaped to engage the ramp portion  424  of the keep-out feature, the stop portion  426  remains within the cavity  410  of the modular jack connector thereby preventing the insertion of the modular plug.  FIG. 4E  on the other hand demonstrates the state of the keep-out feature  414  when the proper modular plug is inserted into the modular jack connector  400 . The proper modular plug will engage the ramp portion  424  thereby biasing the stop portion  426  of the keep-out feature  414  out of the port  410  so that the plug may be inserted into the modular jack connector  400 . 
     As with the embodiments of  FIGS. 1A and 1B , and  3 A and  3 B, the effective length of the feature  414  of  FIGS. 4A and 4B  is increased over prior art solutions, thereby Providing similar benefits to those previously described, especially in the case where the feature  414  is molded or formed as an integral part of the housing. 
     It is also appreciated that various modifications to the embodiments discussed in  FIGS. 1A-4E  could readily be achieved by one of ordinary skill. For example, indicator lights (e.g. LEDs, etc.) could readily be adapted into the modular jack designs of the aforementioned embodiments. For instance, LEDs (such as those disclosed in FIG. 1b of U.S. Pat. No. 6,773,298 previously incorporated by reference herein) could be incorporated into the front face  108  of the modular jack housing  102  of  FIG. 1A . In another variation, LEDs may be incorporated into the front face  208  of the modular jack housing  202  of  FIG. 2A  via methods similar to those disclosed in FIG. 1b of U.S. Pat. No. 6,325,664 previously incorporated herein by reference in its entirety. 
     It will also be understood that the placement of the light sources within the connector housing  102  may be varied. For instance, various optical media could be utilized in conjunction with the modular jack such as the light pipe media disclosed in FIG. 4b of U.S. Pat. No. 6,962,511 incorporated herein by reference in its entirety. 
     In addition to indicator lights such as the embodiments discussed above, EMI shielding such as that disclosed in U.S. Pat. No. 6,325,664 previously incorporated by reference in its entirety may be added to any of the previously disclosed embodiments if desired. See, e.g.,  FIG. 2   b  thereof. Various modifications and permutations to the aforementioned single port modular jack embodiments would be apparent to one of ordinary skill given the present disclosure herein. 
     Multi-Port Embodiment 
     Referring now to  FIG. 5 , a first multi-port embodiment of a modular jack connector  500  manufactured in accordance with the principles of the present invention is shown and described in detail. The modular jack connector  500  of  FIG. 5  comprises a 2×N configuration in which individual ports  510  of the modular jack  500  are arranged in rows and columns. In the present embodiment shown, the modular jack connector  500  comprises an upper port  510   a  and a lower port  510   b . Each port  510  has an integrated keep-out feature  522 , such as those previously described with regards to  FIGS. 1A-4E  above. 
     The multi-port embodiment of  FIG. 5  comprises an insulative housing  502  separated into plug receiving ports  510  and an electronic component containing space  544 . The electronic component containing space  544  may optionally contain a printed circuit board  540  upon which a plurality of electronic components may be mounted. In one embodiment the plurality of electronic components may comprise a plurality of toroidal coils in the form of transformers and choke coils which filter the incoming and/or outgoing signals to the modular jack  500 . The electrical signals pass from the inserted modular plug via contactors  530  through the printed circuit board  540  to terminals  542  or vice versa. Surface mount electronic components may be utilized in conjunction with the aforementioned toroidal components to further signal condition electrical signals passing through the modular jack connector  500 . 
     The modular jack connector  500  of  FIG. 5  also optionally comprises a plurality of light sources  534  (e.g. light-emitting diodes “LEDs” and the like). The light sources  534  for the upper port(s)  510   a  will be routed to the front of the modular jack connector  500  via optical media  536  (so-called light pipes) well known in the electronic connector arts. The modular jack connector housing  502  will also be substantially encased with EMI shielding  532  which acts to prevent and/or dissipate unwanted electrical signals from entering or exiting signals paths located within the modular jack connector  500 . 
     Referring now to  FIG. 6 , a front view illustrating another embodiment of a multi-port 2×N modular jack connector  600  is shown and described in detail. The multi-port embodiment shown in  FIG. 6  comprises three (3) distinct modular jack 2×1 housings  602 . The modular jack housings  602  are “stacked” together to form a multi-port 2×N modular jack connector  600 . The assembled modular jack connector  600  can then be substantially encased with a metallic shield (not shown) for purposes of improving EMI performance. 
     The modular jack housings  602  are preferably held together via connections  650 . These connections  650  may comprise press-fitted posts or other means (e.g. cantilever snaps, adhesives, heat staking, etc.) suitable for combining the housings  602  into a unitary assembly. While the present embodiment of  FIG. 6  illustrates these connections  650  occurring on a side wall of a modular jack housing  602 , these connections  650  may readily be adapted on other faces as well such as the top, bottom, front and/or back face of the housing  602  or any other suitable combination of faces which meets other design constraints such as overall connector footprint and/or height. 
     Each port  610  of the modular jack connector  600  may optionally comprise light sources  634  which are useful to indicate the status of each of the upper  610   a  and lower  610   b  ports. Metallic terminals  642  provide electrical terminations to an external main printed circuit board (not shown). 
     Referring now to  FIG. 7 , an exemplary embodiment of a 1×N multi-port modular jack connector  700  in accordance with the invention is shown and described in detail. The embodiment shown in  FIG. 7  comprises two (2) modular jack housings  702  which are combined similarly to those methods discussed previously with regards to  FIG. 6 , although it is recognized that one of ordinary skill may readily adapt the present modular jack connector to be formed of a unitary housing assembly. However, such a unitary housing may add complexity to the mold of the connector and hence may not be desirable in all applications. 
     The multi-port modular jack connector  700  advantageously comprises a housing  702  made of an insulating material such as a thermoset or thermoplastic polymer material. The housing(s)  702  are generally defined by side walls  704 , front wall  708  and top and bottom walls  706 . The port(s)  710  shown in  FIG. 7  are of the tab down  712  variety, although it is recognized that a tab up configuration (i.e. where tab  712  is positioned adjacent to top wall  706 ) may be readily adapted to the modular jack connector  700  shown in  FIG. 7  by a person of ordinary skill given the present disclosure provided herein. 
     The modular jack connector  700  of the present embodiment incorporates two keep-out features  714  into each of the housings  702  of the modular jack connector  700 . Each keep-out feature  714  is integrally molded into a respective side wall  704  of the housing  702  and first projects in a direction perpendicular to the plug insertion direction with the first cantilever arm section  716 . The first cantilever arm section  716  extends in plane with the side wall  704  of the housing  702  via filleted joints which serve to strengthen the interface between the side wall  704  and its respective keep-out feature  714 . Radial section  718  of keep-out feature  714  transitions the first cantilever arm section  716  into a second cantilever arm section  720  which runs in a direction generally parallel to the modular plug insertion direction and generally perpendicular to the direction of the first cantilever arm section  716 . The length of the first and second cantilever sections  716 ,  720  respectively are governed largely by the mechanical properties of the housing material chosen, the design of which being well within the capability of one of ordinary skill given the present disclosure. 
     The keep-out feature  714  operates similarly to those embodiments shown with respect to the single-port embodiments discussed with regards to  FIGS. 1A-3B , although it is recognized that the keep-out feature discussed with regards to  FIGS. 4A-4E  may readily be incorporated into the multi-port connector  700  of  FIG. 7 . 
     As previously discussed with regards to the single-port embodiments, one distinct salient advantage of the present multi-port embodiment over prior art attempts at mitigating improper plug insertion is that the keep-out feature of  FIGS. 5-7  may be integrally molded (via injection molding processes and the like) so that the additive cost of including a keep-out feature within the modular jack connector is minimized. Therefore this desirable feature can be included with little or no cost to the manufacture of the modular jack providing a distinct competitive advantage over many prior art solutions. In addition as manual assembly processes are avoided, part to part consistency is also maximized as standard quality control procedures can ensure consistent production of the modular jacks over the life of the tooling for the modular jack. 
     It is noted that in the illustrated embodiment of  FIG. 7 , the two interior keep-out features  714  (i.e., those placed directly juxtaposed at the center  751  of the assembly) are separately articulated; i.e., can move independent of one another. This prevents the situation where a properly sized plug inserted into one of the two ports causes one of the two keep-out features  714  (i.e., the interior one) of the other adjacent port to be deflected upward, thereby reducing that second port&#39;s “protection” to one feature (i.e., the one on the outer sidewall). However, it may be desirable in some circumstances to utilize such a scheme, such as e.g., where the costs of separately tooling the devices and mating them together is not offset by any gain in performance (i.e., surety that the one remaining feature  714  will effectively provide the necessary keep-out function). 
     Conversely, in the context of either single-port or multiple-port embodiments as disclosed herein, the two keep-out features  114 ,  214 ,  314 ,  714  associated with a given single port can be coupled or ganged to one another, such that their operation is not independent. For example, in one variant, the two (left and right) keep-out features  114  of  FIG. 1A  are coupled via a structure (e.g., bar) that resides in a lateral groove formed within the top surface of the housing (not shown). This approach may be desirable for, inter alia, cases where the sidewalls of the housing are required to be very thin, and hence the two features  114  would be subject to significant torsion (i.e., flex in a rotational or other direction not desired) if not otherwise coupled (stabilized) to one another. 
     Moreover, since the exemplary features described herein do not in any way extend beyond the plane of the outer sidewall of the housing (i.e., are at maximum flush, or further recessed), heterogeneous keep-out solutions can be used in the device of  FIG. 7 . For example, the approach shown in  FIG. 1A  may be used in a first connector, the approach of  FIG. 2A  in a second connector, and that of  FIG. 3A  in a third connector, and so forth. 
     It is also appreciated that various modifications to the embodiment(s) discussed with respect to  FIG. 7  could readily be achieved by one of ordinary skill. For example, indicator lights (e.g. LEDs, etc.) could readily be adapted into the modular jack designs of the aforementioned embodiment(s). For instance, LEDs (such as those disclosed in FIG. 1b of U.S. Pat. No. 6,773,298 previously incorporated by reference herein) could be incorporated into the front face  708  of the modular jack housing  702  of  FIG. 7 . 
     It will also be understood that the placement of the light sources within the connector housing  702  may be varied. For instance, various optical media could be utilized in conjunction with the modular jack such as the light pipe media disclosed in FIG. 4b of U.S. Pat. No. 6,962,511 previously incorporated herein by reference in its entirety. 
     It will be further noted that each of the foregoing embodiments of the connector assembly of the invention may be outfitted with one or more external or internal noise/EMI shields in order to provide enhanced electrical separation and reduced noise between conductors and electronic components. As an example, the internal shielding arrangement(s) described in co-owned U.S. Pat. No. 6,585,540 entitled “Shielded Microelectronic Connector Assembly and Method of Manufacturing”, filed Dec. 6, 2000, and assigned to the co-assignee hereof, incorporated by reference herein in its entirety, may be adapted for use with the present invention, whether alone or in conjunction with other such shielding methods. Specifically, the single- or multi-port port embodiments of the present invention may be fitted with a substrate shields to limit electromagnetic noise transferal through the bottom of the connector. Similarly, side- or lateral shield elements such as those taught in the foregoing application may be used between individual ones of the connectors in the multi-port embodiment of the present invention. An external or noise shield of the type illustrated in  FIG. 5  herein, or other comparable design, may be employed in addition or in the alternative to the foregoing internal shields as well. 
     In addition, in some instances is may be desirable that one or more ports of the multi-port embodiments discussed with regards to  FIGS. 5-7  not include keep-out features within the receptacle of that port  710 . It is recognized that such a modification would be well within the capability of one of ordinary skill given the present disclosure herein. 
     In yet another embodiment, the ports used may be heterogeneous, with all or less than all of them being equipped with keep-out features. For example, a modular-over-USB configuration of the type well known in the networking arts may employ a modular jack with a keep-out feature, while the USB connector does not (i.e., USB connector form factor is effectively sui generis, and hence does not really require any sort of “keep-out” arrangement). 
     Shield-Based Variants 
     As is well known in the connector (and particularly modular jack) arts, noise shielding of the type previously described is very useful at mitigating inter alia internal or external EMI associated with the operation of high-frequency circuitry. Accordingly, such shielding is very typically present on connectors, and as described subsequently herein is used to advantage for purposes of excluding improperly sized plugs from the connector. 
     In one exemplary embodiment ( FIG. 8A ), the shield  852  comprises a wrap-around tin alloy Faraday shield of the type known in the art, although other configurations and materials may be used with equal success. The connector housing  853  comprises a plurality of grooves or slots  854  formed in its upper surface (and which communicate at least in some degree with the modular plug receiving port  856  of the housing); these slots contain respective somewhat free-floating metallic arm members  858  as shown. The arm members comprise a front abutment section  860 , an elongated portion  862 , and a rear retention portion  864 . 
     The rear retention portion  864  comprises in the illustrated embodiment a curved or bent portion  865 , and an upper shield contact portion  866  as shown. The upper contact portion  866  is configured to contact the interior side of the top wall of the shield  852 , thereby effectively capturing the arm members  858  within the slots, and further allowing for the deflection of the members  858  when the proper sized plug is inserted into the port. Specifically, since the contact portion  866  is in contact with the substantially rigid shield  852 , the curved portion  865  bends under upward deflection of the member  858  by the plug (in effect acts like a spring). The elongated portion  862  can be made to flex somewhat also if desired, thereby adding two levels of resiliency to the assembly. 
     It will be appreciated that other configurations of springs or bias forces can be used consistent with the arm members  858  of the present invention. For example, in one variant (not shown), the contact portion is adapted to extend further forward in the slot, thereby making the arm members  858  more of a “U” shape than a “J” shape” as in the embodiment of  FIG. 8A . Moreover, the arm members  858  may be formed of other materials that provide the desired properties (e.g., substantially rigid polymers, etc.), and may even comprise multiple discrete components. They may also be attached to the shield  852  (such as via an adhesive, tack- or other weld, etc.), and may even be formed as part of the shield (see, e.g., the exemplary approach of  FIG. 8B ). 
     Method of Manufacture 
     Referring now to  FIG. 9 , a method  900  of manufacturing the aforementioned single port modular jack connector (i.e. modular jack connectors  100 ,  200 ,  300 ,  400 ) is described in detail. It is noted that while the following description of the method  900  of  FIG. 9  is cast primarily in terms of a single port modular jack connector assembly, the broader method of the invention is equally applicable to multi-port modular jack connectors with housings formulated from a unitary housing. 
     At step  902 , the modular jack connector housing is injection molded using techniques well understood in the modular connector arts. 
     At step  904 , any inductive electronic components used in the device are wound using well known techniques. These inductive electronic components may include, without limitation, toroidal transformers, choke coils, surface-mountable chip inductors and the like. 
     At step  906 , any electronic components used in the device are mounted on a printed circuit board to be mounted inside of the modular jack connector. These electronic components can include, without limitation, those inductive electronic components manufactured at step  904  and/or other electronic components such as chip-type capacitors, integrated circuits and the like. These electronic components may be attached to the printed circuit board using well known techniques such as IR reflow, hand soldering, wave soldering and the like. 
     At step  908 , the populated printed circuit board (if used) is inserted inside of the modular jack connector housing manufactured at step  902 . 
     At step  810 , the assembled modular jack connector is optionally tested to ensure compliance with both mechanical and/or electrical specifications. 
     Referring now to  FIG. 10 , a method  1000  of manufacturing the aforementioned multi-port modular jack connectors (i.e. modular jack connectors  500 ,  600 ,  700 ) is described in detail. At step  1002 , the modular jack connector housings are injection molded using standard processing techniques well known in the modular connector arts. 
     At step  1004 , the modular jack connector housings are assembled together to form the end product multi-port 2×N or 1×N modular jack connector. These modular jack connector housings are combined using those techniques previously discussed above such as cantilever snaps, press-fit posts, adhesives and the like. 
     At step  1006 , electronic components (if used) are mounted on the printed circuit board (or other structure, if any) to be mounted inside of the multi-port modular jack connector. These electronic components can include, without limitation, inductive electronic components wound using well known techniques. These inductive electronic components may include, without limitation, toroidal transformers, choke coils, surface-mountable chip inductors and the like. These electronic components may also include other electronic components such as chip-type capacitors, integrated circuits and the like. These electronic components may be attached to the printed circuit board using well known techniques such as IR reflow, hand soldering, wave soldering and the like. 
     At step  1008 , the populated printed circuit boards or other assemblies (if used) are inserted inside of the multi-port modular jack connector housing manufactured at step  1002 . 
     At step  1010 , the assembled multi-port modular jack connector is optionally tested to ensure compliance with both mechanical and/or electrical specifications.
