Description

LOCAL AREA NETWORK INTERFACE
The instant invention relates to a device for accommodating communication network systems where more than one type of interface is utilized #n the same local area. Modular connections allow adaptation between two different interface devices using two different telecommunication cables.
Communication network systems vary in scope and design as directed by the manufacturers of the interfacing devices . Some network interface devices utilize shielded systems whereas others utilize an unshielded system. Several designs of interfacing devices are known in the art.
For example, U . S . Patents 4, 501 , 459 and 4, 193 , 654 relate to shielded connectors for coupling two shielded cables of a shielded information network system. These connectors are hermaphroditic in nature, that is , two identical connectors are utilized for the conne'ction, and each connector can accommodate four lines of information. •
Connectors for unshielded network interfaces are also known, for example, U . S. Patents 4, 210, 376 ; 4, 221 ,458 ; 4, 292, 736 and 4, 231 , 628 relate to network connectors or modular jacks , which are mountable to printed circuit boards , and are capable of accommodating between four and eight lines of communication. These connectors include stamped and formed contacts for receiving a mating plug.
Edge card connectors for interconnecting printed circuit boards to multi- conductor cable are also known in the art. For example, U. S. Patent 3 ,860,318 shows an edge connector having stamped and formed contacts providing interconnection to circuit board traces on one end, while on the opposite end, providing a barrel- type insulation displacement device for terminating individual conductors.
There has not heretofore been a means , however, for modular interconnection of and local mounting of, the inter- connection devices required to terminate two distinct local area networks , that is, a shielded system and an unshielded system .
It is , therefore, an object of the invention to provide a universal system of interconnections, compatible for a shielded and an unshielded system.
It is an object of' the present invention to provide an interconnection system that is compatible with the present interconnection devices.
It is an object of the instant invention to provide an interconnection system utilizing as many interchangeable components as possible, between the shielded and unshielded system.
It is an object of the instant invention to provide an interconnection system that may be utilized with an all shielded system, an all unshielded system or with a combination shielded-unshielded system.
Other objects will be apparent from the detailed description of the preferred embodiment.
The foregoing objects are achieved in the instant invention by providing a universal wall box having identical and shielded cavities therein. A printed circuit board to barrel insulation displacement device is utilized, interconnecting the conductors of the shielded or unshielded cable to the insulation displacement portions. A printed circuit board having mounted thereon a connector for either a shielded or unshielded system is interconnected to the edge card connector. The cavities may be used for mounting shielded or unshielded connectors in any combination. A mating shielded or unshielded connector can then be connected to the local interfaces, interconnecting the network interface systems with the communication network system .

Referring to Figure 1 there is shown an interface interconnection system for interconnecting two different interface systems. More specifically there is shown a two-cavity wall box 2 for receiving from the rear two edge connectors 150A and 150B , the edge connector 150A interconnecting an unshielded cable 120 and the edge connector 150B interconnecting a shielded cable 130. The edge connectors 150A and 150B are inserted from the rear of the wall box and are locked in position within the wall box. The modular jack interface assembly 390 and the data interface assembly 200 are each interconnected with an* edge card and each interface assembly 390, 200 may be inserted through the front of a wall box for interconnection with the respective edge connectors 150A, 150B . A face plate 400 is then placed over the completed assembly to cosmetically blend the entire system in with the wall.
Referring now to Figure 2, there is shown the system of Figure 1 completely assembled. A shielded cable 130 is shown entering the wall box from the rear interconnected to data interface assembly 200. Also shown is unshielded cable 120 inserted into the wall box from the rear and interconnected with modular jack assembly 390. Modular plug 490 is shown poised for reception into modular jack assembly 390. Referring now to Figure 3 there is shown the assembly of Figure 2 with the face plate exploded away from the completed assembly, showing the adaptor inserts 300, 380 in an assembled configuration. The wail box 2 will now be described in greater detail with reference to Figures 4-4C . Referring first to Figure 4 the wail box 2 is shown as having two receiving cavities 12 and 1 . The wall box 2 is generally comprised of two endwalls 5 and two f ' sidewails 4 with two mounting bosses 10 extending from opposite endwalls 6. The upper cavity 12 is defined by sidewails 16 , floor 18 , ceiling 20 and backwall 28. It will be noticed that backwall 28 does not extend from the ceiling 20 to the floor 18 , but rather , extends only from the ceiling 20 , the wall 28 ending with a lower edge 50. As such , there is an opening from the front of the wall box completely through to the rear of the wall box, providing an opening 48 for either edge connector 150A or 1 508. Located on the edge 50 of wall 28 is a latch receiving area defined by side edges 52 and upper edge 54.
Similarly lower cavity 14 is defined by sidewails 22 , floor 24 , ceiling 25 and rearwall 30. Once again , rearwall 30 does not extend from the ceiling 26 to the floor 24, but rather, terminates with edge 58 providing a cavity 56 for receiving either edge connector 150A or 150B from the rear . Also defined on edge 58 of wall 30 is a latch-receiving area defined by side edges 60 and upper edge 62.
Located in the center of wall 28 is aperture 32 having a locking tab 34 , and located in the center of wall 30 are apertures 36 , 40 having locking tabs 38 , 42 respectively . I ncluded in the lower mounting boss 1 0 is provided an aperture 44 having a locking tab 46.
Extending forwardly from the sidewails 16 of upper cavity 12 and forwardly from the sidewai ls 22 of the lower cavity 14 are alignment arms 64 and 78 , respectively . Referring now to both Figures 4A and 48 , the geometrical configuration of alignment arms 64 is shown in greater detail . The alignment arms 64 have a surface 70 which is recessed from the sidewails 16 and extend rearwardly into the cavity to a contiguous lead-in surface 66. The lead-in surface 66 then extends rearwardly back to a point planar with sidewails 16 , sidewall 1 6 then being recessed back to -δ- a surface 72 , the sudden recess causing a locking surface 88. The alignment arm 78 has a Uke configuration to that of arm 64 having a recessed surface 84 , a lead-in surface 80 and a locking back surface 82 , as shown in Figure 4A.
As shown in Figure 4A wail box 2 has a wail 28 and a wall 112 extending downwardly through the center of the box, and extending rearwardly from wall 28 is floor 92. Located directly above wall 92 are ribs 94. Extending rearwardly from wall 1 12 is a floor 96 and directly below floor 96 are ribs 98. Extending from , and contiguous with lower floor portion 24 is a floor 110 extending rearwardly into the wall box.
Referring again to Figures 4A and 48 , the rearward part of the upper cavity is flanked by a pair of recessed walls 76 , the recessed walls 76 being offset from walls 72 forming a shoulder 74. Likewise, the lower cavity portion is flanked by a pair of recessed walls 90 , the walls 90 recessed from walls 86 forming a shoulder 88. Also shown in 4B is floor 96 extending rearwardly from wall 1 12. At the rearward edge of floor 96 are located two cable cut-out portions 100 and 102. Referring now to Figure 4C , the rear plan view of wall box 2 shows floor 96 once again with cable cut-out portions 100 and 102. Floor 92 is also shown extending from wail 28 , floor 92 having a cable cut-out portion 104 laterally aligned with cut-out portion 100 in floor 96. Floor 1 10 is also shown having a cable cut-out portion 106 which is laterally aligned with cable cut-out portion 102 in floor 96. Figure 4C also shows in greater detail the card edge connector receiving areas 48 and 56.
Finally, the entire wall box 2 is a one-piece molded unit plated with a metallic coating to shield the entire box. The preferred embodiment utilizes a nickel over copper piating , although other combinations of metals could be utilized without varying from the scope or intent of the instant invention .
Referring next to Figure 7 the data interface assembly 200 is shown in greater detail , the assembly 200 comprising housing 202 , terminals 214, stuffer cap 220 , upper and lower shield members 260 , 230 , and printed circuit board 280.

Referring now to Figures 9 , 13 and 14 there is shown in greater detail the data interface assembly adapter insert 300. The adapter 300 comprises sidewails 304 and endwalls 302. Extending forwardly from the sidewails 304 are two locking latches 306 comprising a lead-in section 308 and a back latching surface 310 ( Figure 9) . Although adaptor 300 is molded from a plastic material , the complete interior portion of the adaptor is plated with conductive material 312 for shielding purposes. Referring more specifically to Figure 14, on the interior of the endwalls 302 there is located two locking shoulders 320 extending from the interior of the endwalls 302. Extending from the interior of one of the sidewails ,304 is a T-bar 314 having a leg portion 318 and a lead-in surface 316. Opposed from the T-bar 314 is a T-slot 326 having a lead-in surface 328 and a backwall 330 ( Figure 12 ) . Defined by the sidewails and the interior surfaces of the adaptor 300 is a data interface assembly receiving area 322.
Referring now to Figure 1 1 , there is shown a modular jack 390 and a modular jack adaptor 380. The modular jack 390 is similar in design to those disclosed in U . S. Patents 4, 210 ,376; 4,221 ,458; 4,231 ,628; and 4 , 292 ,736 , whose disclosure is incorporated herein by reference. The modular jack 390 has a plug-receiving opening 394 on the forward surface of the modular jack 390. Modular jack 390 further comprises a locking shoulder 392 and stamped and formed contacts 396.

Extending from sidewall 352 is a connection tab 364 having a connecting slot 366 therein. Also located in sidewail 352 is a wire-receiving slot 358. Extending from the forward edge of sidewall 356 is a connection tab 368 having a connection siot 370 therein , A second wire-receiving slot 360 is located in sidewail 356 in alignment with wire-receiving slot 358. Located in sidewall 356 and laterally opposed from wire-receiving siot 360 is wire opening 372. Stamped out of the front wall 354 is a shielding tongue 362.
Referring now to Figures 5 and 6 , there is shown in detail the card edge connector either 150A or 150B , which is similar in design to that disclosed in U .S. Patent 3 ,860,318 , whose disclosure is incorporated herein by reference. The connector 150 comprises top edge 152 , bottom edge 154, sidewails 160, shoulders 174 , recessed sidewails 162 and a backwall 158. Extending inward from the backwall 158 are terminal-receiving slots 172 for receiving contact terminals 180. Contact terminals 180 comprise a barrel-type insulation displacement terminal 182 and a resilient contact portion 184. Also shown in Figure 6 is a stuffer cap 190 which has a stuffer post 192 with a surrounding circular aperture 194. The outer diameter of stuffer post 192 is smaller than the inside diameter of the barrel insulation displacement section 182. The stuffer cap 190 further includes wire-receiving slot 196. Referring again to Figure 5 , card edge connector 1 50A or 1508 includes a latch 164 extending from the backwall 158 and disposed above the top wall 152. The latch 164 comprises a lead-in section 166 with a latching back surface 168.
The instant invention can be used as a network interface outlet for any combination of network interface devices . That is two unshielded cables 120 could be interconnected to two unshielded modular jacks 390, or two shielded cables 130 could be interconnected to two data interface assemblies 200 or one unshielded cable 120 and one shielded cable 1 30 could be interconnected to respective interface assemblies 390 , 200 , and either interface assembly 390 or 200 can be interconnected to either cavity 12 , 1 as the adapter inserts 380, 300 and the edge connectors 150A, 1508 are interchangeable in either of the cavities 12 , 14.
In order to interconnect a shielded cable 130, it is first necessary to assemble the shielded data interface assembly 200. Referring to Figure 7 , the housing 202 must first have the terminals 214 installed therein , the side edges of the terminal 214 being received in the terminal grooves 210 in floor 205. When the terminals 214 are fully installed , the resilient contact portion 218 is disposed in the forward mating end 203. The individual conductors 224 may then be terminated to the barrel portion of the terminal 216 by placing the individual conductors in the wire-receiving slots 226 of the stuffer cap 220. With the four conductors in place in the respective wire-receiving slots 226 , as shown in Figure 7 , the cap 220 is then lowered onto the housing 202 , the locating ribs 222 being disposed in the stuffer cap receiving slots 212 which aligns stuffer posts (not shown) in the stuffer cap with the barrel terminals 216 which forces the individual conductors 224 into the barrel 216 terminating respective conductors into respective slots 217.
The upper and lower shielding covers 260 , 230 are then installed over the housing 202 completely shielding the contact terminals 214. The lower cover 230 is first placed over the lower portion of the housing , the mounting lugs 206 fitting into the mounting slots 248 on the sidewails 232. The upper shield 260 may then be installed over the housing 202 , the shielding wings 262 being placed into the receiving slots 208 and the locking tabs 270 being placed in the mounting slots 250. The edge card 280 is then connected to the shielding members , the cutout portion 286 of the edge card 280 sliding over the upper and lower shield members 260 , 230 and sliding into slots 268 and 244 of upper and lower shield 260 , 230 , respectively . This places the edge card mounting tabs 282 in alignment with mounting tabs 266 and 246 of the shielding members . The tabs 282 are then soldered to mounting tabs 266 , 246 to mechanically mount the edge card 280 to the shielding members 230, 260 and to electrically interconnect ground traces 290 on edge card 280 to the shield members 260, 230. The individual conductors 224 may then be soldered in place to solder pads 288 in edge card 280 interconnecting the individual conductors 224 to the traces 284. As finally assembled, the contact resilient portion 218 is electrically interconnected to the conductive traces 284 on the edge card 280 via the contact terminal 214 and the individual conductors 224, and the shielding members 230, 260 are commoned to the grounding traces 290.
The completed data interface assembly 200 may then be installed in a respective data connector adaptor 300 as shown in Figure 9. The data interface assembly 200 is installed into the assembly receiving area 322, the assembly 200 sliding into the receiving area until the mounting tabs 238 latch over the locking shoulders 320 of the adaptor 300 which also places mounting tabs 242 in abutment with the front surfaces 332 (Figure 13) of the adaptor 300. When latching tabs 236 are in their locked position over the shoulders 320, they are also resiliently biased against the interior surface of endwalls 302. As the interior of adaptor 300 is completely plated with plating material 312, the tabs 236, biased against the endwalls 302 , common the shielding members 230 and 260 to the plating material 312.
The individual conductors 132 of shielded cable 130 are then terminated to the contact terminals 180 of edge card connector 150B . The edge card connectors 150A, 150B are identical in design, the only distinguishing feature is whether the connector is used with a shielded or an unshielded cable. When referring to the design aspects of the connectors, as in Figures 5 and 6 , reference will be made to connector 150, generally. However, when a particularly located connector is to be noted, the postscript will also be utilized.
Each individual conductor 132 would be placed in the wire- receiving slots 196 of the stuffer cap 190 (Figure 6) and would be terminated in the individual insulation displacement barrels 182, as shown in Figures 5 and 6. With the individual conductors 132 terminated to the contact terminals 180 , the edge card connector 1508 could be inserted from the rear side of wall box 2 through either of the connector-receiving areas 48 or 56 (Figure 4C) . if the edge card connector 1508 is placed in the upper cavity 48 , the edge card connector 1508 moves forwardly until the shoulder 174, between sidewails 160 , 162 , abuts shoulder 74 in the wail box 2 , as shown in Figures 4A and 4D . When installing the edge connector 150B , the bottom surface 154 lies along the floor 18 and when shoulders 174 abut the shoulder 74 the latch member 164 latches in place such that latch member 164 fits into the latch-receiving slot defined by surfaces 52 and 54 (Figure 4) which locks the edge card connector 150B in place.
The assembled data interface assembly 200 and adaptor 300 may then be installed into upper cavity 12 from the front side of the wall box 2. The printed circuit board 280 first enters the cavity* and begins entry into edge connector 170. The latch 306 then .begins engagement along surfaces 70 of alignment arms 64 which aligns the assembly 200 and adaptor 300 in the proper vertical orientation. Continued insertion of the adaptor causes the lead-in sections 308 of the adaptor 300 to ride up on the ramp 66 of the alignment arm 64 and finally lock itself, latch back surface 310 adjacent shoulder 68 of wall box 2 , as shown in Figures 4A and 4D .
A shield member 350 would then have to be installed from the rearward side of the wail box 2 to shield the back side of data assembly 200. The cable 130 would first be disposed in the opening 372 of the shielding member 350 with the cable shielding 134 adjacent the resilient tongue 362 as shown in Figure 10. The shielding member 350 would then be installed into the back portion of wall box 2 , the sidewall 354 being placed between floor 92 and ribs 94 and sidewall 352 being placed above but adjacent to floor 96. The shielding member 350 is inserted into the wall box until tab 368 is inserted into aperture 32 and siot 36 being locked onto the locking tab 34; and locking tab 364 is disposed in siot 36 with the siot 366 overlying the tab 38.
It should be noted that the data connector assembly 200 is redundantly grounded , each level of grounding being commoned to a common potential . The assembly 200 includes a first level grounding as the shielding members 230 , 260 surround the housing 202. The assembly 200 includes a second level of grounding as the wall box 2 and the adaptor 300 are plated and commoned to one another at their point of joinder , that is , between front edge 307 of adaptor 300 , and front edge 7 of wall box 2. Furthermore the two levels of grounding are commoned to one potential , as tabs 236 on lower shielding member 230 are resiliency biased against the interior of sidewails 302.
The shielded cable 130 will be oriented downwardly as shown in Figure 4D with the cable 130 disposed in cable cutouts 104 and 100. With the shielded cable 130 disposed in this manner, the back edge of wire entry slot 102 backs up the shielded cable 130 , so that, the resilient tongue 362 maintains adequate contact with the shielding braid .
I f a second shielded cable is to be used , a second edge card connector will be inserted into the back side of the wail box 2 as previously described , and into the lower connector-receiving area 56. A second shielding member 350 would then be utilized , its orientation as shown in Figure 10. It should be noted that the shield member 350 can be used in either upper 12 or lower 14 cavity , by simply inverting the shielding member . The shielding member 350 would be installed from the back side of the wall box with the sidewall 352 disposed between the ribs 98 and the floor 96 and the sidewall 356 disposed below but adjacent to floor 110. With the second shielded cable 130 inserted in the opening 372 , the second shielding member 350 would be inserted until the tab 364 extends into aperture 40 and until tab 368 extends into aperture 44 , slots 366 , 370 overlying tabs 42 , 46 respectively . lf an unshielded cabie 120 and a modular jack interface assembly 390 were to be installed in cavity 1 4, a second shielding member 350 would not be added to the back side of wall box 2 as previously described. Rather, the individual conductors 122 of the unshielded cabie 120 would be terminated to the edge card connector 150A and the connector would be installed into receiving area 56 , shoulders 174 abutting shoulder 88 of wail box 2. Furthermore, bottom surface 154 would be disposed adjacent to floor 1 10 and latch member 164 would be locked in place in the siot defined by surfaces 60 and 62.
The modular jack interface assembly 390 would then be installed onto the adaptor 380 , the latching members 384 locking onto shoulders 392 of the modular jack 390. As installed , the adaptor 386 is aligned with plug receiving opening 394 for reception of a modular plug . The modular jack 390 and adaptor 380 would then be installed into cavity 14 with the edge card 396 first mating with the edge card opening 370 of the connector 150A. The latch arms 382 are then aligned with alignment arms 78 , the ramps 388 in sliding engagement with surfaces 84 of alignment arms 78 until the latch arms 382 are locked behind surfaces 82 as shown in Figure 1 1 .
The face plate 400 may then be placed over the wall box 2 face plate openings 402 and 404 slidably received over adaptors 380 and 300 respectively. As installed the assembly is ready for reception of a modular plug data connector 390 as shown in Figure 2. The assembly is also ready for reception of a data interface connector of the type disclosed in U . S . Patents 4, 193 ,654 and 4 , 501 , 459 , also incorporated herein by reference.
Hermaphroditic data connector 500 when interconnected to data interface assembly 200 interconnects like terminals in connector 500 with terminals 214, and commons like shielding wings with shielding wings 538 and shielding wings 262. When the data connector 500 is inserted the T-bar overlaps T-slot 326 , and iikewise the T-slot of data connector 500 overlaps T-slot Thus , the instant invention allows versatility with respect to data interfacing assemblies, and also allows for local access to any combination of shielded and unshielded systems. As each of the elements are modular in nature, the system allows for easy installation and connect/disconnect. The system also allows for interchangability between shielded and unshielded systems as either cavity of the wall box may be used for either system and as the same edge card connectors are utilized in both systems. Finally, the assembly allows for interconnection to existing data interconnection systems .
