- 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.
- a second edge card connector will be inserted into the back side of the wall box 2 as previously described, and into the lower connector-receiving area 56.
- a second shielding member 350 would then be utilized, its orientation being 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 engaging tabs 42, 46 respectively.
- 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 cable 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 wall box 2. Furthermore, bottom surface 154 would be disposed adjacent to floor 110 and latch member 164 would be locked in place in the slot defined by surfaces 60 and 62.

Abstract
Description
- The present invention relates to an interface for accommodating communication network systems where more than one type of interface device is utilized in 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, US-A-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 connection, and each connector can accommodate four lines of information.
- Connectors for unshielded network interfaces are also known, for example, US-A-4 210 376; 4 221 458; 4 292 736 and 4 231 628 relate to data 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, US-A-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.
- GB-A-1 171 549 describes an adaptor for enabling a standard electronic module, which can be slid into racks or crates to form a complete system of electronic apparatus and which has pin contacts on the back of the module, to be connected to a rack or crate utilizing edge connector strips.
- There is disclosed in US-A-4 407 559 a local area network receptacle assembly for interconnection of electronic equipment to a local area network, including a modular electrical connector having at least one signal carrying contact disposed at a front mating face for interconnection with at least one mating contact of a complementary connector, the modular electrical connector being electrically connected to a shielded cable having individual data communication conductors which form the network, the modular electrical connector being enclosed by a wall box having at least two identical cavities each having an open front face and a partially open rear face.
- The present invention consists in an interface interconnection system for providing an interface to a communications network, comprising a data connector engageable by a complementary connector for connecting an electronic component to the network, said data connector including an insulating terminal support housing having a front mating face and a rear face and mounting a plurality of terminals having contact portions engageable with contacts of the complementary connector, said data connector also having an edge card which extends rearwardly and which has data traces electrically connected to terminals of the terminal support housing, a wall box housing the data connector in the wall box with its front face accessible to the complementary connector, and an edge card connector mounted in the wall box for terminating a multi-conductor communications cable of the network, the edge card of the data connector being plugged into the edge card connector.

Stamped out of thefront wall 354 is a shieldingtongue 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.-A-3 860 318.
- The
connector 150 comprisestop edge 152,bottom edge 154,sidewalls 160, shoulders 174, recessedsidewalls 162 and abackwall 158. Extending inward from thebackwall 158 are terminal-receivingslots 172 for receivingcontact terminals 180.Contact terminals 180 comprise a barrel-typeinsulation displacement terminal 182, and aresilient contact portion 184. Also shown in Figure 6 is astuffer cap 190 which has astuffer post 192 with a surroundingcircular aperture 194. The outer diameter ofstuffer post 192 is smaller than the inside diameter of the barrelinsulation displacement section 182. Thestuffer cap 190 further includes wire-receivingslot 196. Referring again to Figure 5,card edge connector 150A or 150B includes alatch 164 extending from thebackwall 158 and disposed above thetop wall 152. Thelatch 164 comprises a lead-insection 166 with a latching backsurface 168. - The instant embodiment 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 unshieldedmodular jacks 390, or two shieldedcables 130 could be interconnected to twodata interface assemblies 200 or oneunshielded cable 120 and one shieldedcable 130 could be interconnected torespective interface assemblies interface assembly cavity edge connectors 150A, 150B are interchangeable in either of thecavities - In order to interconnect a shielded
cable 130, it is first necessary to assemble the shieldeddata interface assembly 200. Referring to Figure 7, thehousing 202 must first have theterminals 214 installed therein, the side edges of the terminal 214 being received in theterminal grooves 210 infloor 205. When theterminals 214 are fully installed, theresilient contact portion 218 is disposed in theforward mating end 203. Theindividual conductors 224 may then be terminated to the barrel portion of the terminal 216 by placing the individual conductors in the wire-receivingslots 226 of thestuffer cap 220. With the four conductors in place in the respective wire-receivingslots 226, as shown in Figure 7, thecap 220 is then lowered onto thehousing 202, the locatingribs 222 being disposed in the stuffercap receiving slots 212 which aligns stuffer posts (not shown) in the stuffer cap with thebarrel terminals 216 which forces theindividual conductors 224 into thebarrel 216 terminating respective conductors intorespective slots 217. - The upper and lower shielding covers 260, 230 are then installed over the
housing 202 completely shielding thecontact terminals 214. Thelower cover 230 is first placed over the lower portion of the housing, the mountinglugs 206 fitting into the mountingslots 248 on thesidewalls 232. Theupper shield 260 may then be installed over thehousing 202, the shieldingwings 262 being placed into the receivingslots 208 and the lockingtabs 270 being placed in the mountingslots 250. Theedge card 280 is then connected to the shielding members, thecutout portion 286 of theedge card 280 sliding over the upper andlower shield members slots lower shield card mounting tabs 282 in alignment with mountingtabs tabs 282 are then soldered to mountingtabs edge card 280 to the shieldingmembers edge card 280 to theshield members individual conductors 224 may then be soldered in place to solderpads 288 inedge card 280 interconnecting theindividual conductors 224 to thetraces 284. As finally assembled, the contactresilient portion 218 is electrically interconnected to the conductive traces 284 on theedge card 280 via thecontact terminal 214 and theindividual conductors 224, and the shieldingmembers - The completed
data interface assembly 200 may then be installed in a respectivedata connector adaptor 300 as shown in Figure 9. Thedata interface assembly 200 is installed into theassembly receiving area 322, theassembly 200 sliding into the receiving area until the mountingtabs 236 latch over the lockingshoulders 320 of theadaptor 300 which also places mountingtabs 242 in abutment with the front surfaces 332 (Figure 13) of theadaptor 300. When latchingtabs 236 are in their locked position over theshoulders 320, they are also resiliently biased against the interior surface ofendwalls 302. As the interior ofadaptor 300 is completely plated with platingmaterial 312, thetabs 236, biased against theendwalls 302, common the shieldingmembers plating material 312. - The
individual conductors 132 of shieldedcable 130 are then terminated to thecontact terminals 180 of edge card connector 150B. Theedge 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 toconnector 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-receivingslots 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 theindividual conductors 132 terminated to thecontact terminals 180, the edge card connector 150B could be inserted from the rear side ofwall box 2 through either of the connector-receivingareas 48 or 56 (Figure 4C). If the edge card connector 150B is placed in theupper cavity 48, the edge card connector 150B moves forwardly until theshoulder 174, betweensidewalls shoulder 74 in thewall box 2, as shown in Figures 4A and 4D. When installing the edge connector 150B, thebottom surface 154 lies along thefloor 18 and whenshoulders 174 abut theshoulder 74 thelatch member 164 latches in place such thatlatch member 164 fits into the latch-receiving slot defined bysurfaces 52 and 54 (Figure 4) which locks the edge card connector 150B in place. - The assembled
data interface assembly 200 andadaptor 300 may then be installed intoupper cavity 12 from the front side of thewall box 2. The printedcircuit board 280 first enters the cavity and begins entry intoedge connector opening 170. Thelatch 306 then begins engagement alongsurfaces 70 ofalignment arms 64 which aligns theassembly 200 andadaptor 300 in the proper vertical orientation. Continued insertion of the adaptor causes the lead-insections 308 of theadaptor 300 to ride up on theramp 66 of thealignment arm 64 and finally lock itself, with back latchingsurface 310adjacent shoulder 68 ofwall box 2, as shown in Figures 4A and 4D. - A
shield member 350 would then have to be installed from the rearward side of thewall box 2 to shield the back side ofdata assembly 200. Thecable 130 would first be disposed in theopening 372 of the shieldingmember 350 with thecable shielding braid 134 adjacent theresilient tongue 362 as shown in Figure 10. The shieldingmember 350 would then be installed into the back portion ofwall box 2, thesidewall 354 being placed betweenfloor 92 andribs 94 andsidewall 352 being placed above but adjacent tofloor 96. The shieldingmember 350 is inserted into the wall box untiltab 368 is inserted intoaperture 32 andslot 370 is locked onto thelocking tab 34; andlocking tab 364 is disposed inslot 36 with theslot 366 engaging thecab 38. - It should be noted that the
data connector assembly 200 is redundantly grounded, each level of grounding being commoned to a common potential. Theassembly 200 includes a first level grounding as the shieldingmembers housing 202. Theassembly 200 includes a second level of grounding as thewall box 2 and theadaptor 300 are plated and commoned to one another at their point of joinder, that is, betweenfront edge 307 ofadaptor 300, andfront edge 7 ofwall box 2. Furthermore the two levels of grounding are commoned to one potential, astabs 236 onlower shielding member 230 are resiliently biased against the interior ofsidewalls 302. - The shielded
cable 130 will be oriented downwardly as shown in Figure 4D with thecable 130 disposed incable cutouts cable 130 disposed in this manner, the back edge ofwire entry slot 102 backs up the shieldedcable 130, so that, theresilient tongue 362 maintains adequate contact with the shielding braid. - If a second shielded cable is to be used, a second edge card connector will be inserted into the back side of the
wall box 2 as previously described, and into the lower connector-receivingarea 56. Asecond shielding member 350 would then be utilized, its orientation being as shown in Figure 10. It should be noted that theshield member 350 can be used in either upper 12 or lower 14 cavity, by simply inverting the shielding member. The shieldingmember 350 would be installed from the back side of the wall box with thesidewall 352 disposed between theribs 98 and thefloor 96 and thesidewall 356 disposed below but adjacent tofloor 110. With the second shieldedcable 130 inserted in theopening 372, thesecond shielding member 350 would be inserted until thetab 364 extends intoaperture 40 and untiltab 368 extends intoaperture 44,slots tabs - If an
unshielded cable 120 and a modularjack interface assembly 390 were to be installed incavity 14, asecond shielding member 350 would not be added to the back side ofwall box 2 as previously described. Rather, the individual conductors 122 of theunshielded cable 120 would be terminated to theedge card connector 150A and the connector would be installed into receivingarea 56, shoulders 174 abuttingshoulder 88 ofwall box 2. Furthermore,bottom surface 154 would be disposed adjacent tofloor 110 andlatch member 164 would be locked in place in the slot defined bysurfaces - The modular
jack interface assembly 390 would then be installed onto theadaptor 380, the latchingmembers 384 locking ontoshoulders 392 of themodular jack 390. As installed, theadaptor 380 is aligned withplug receiving opening 394 for reception of a modular plug. Themodular jack 390 andadaptor 380 would then be installed intocavity 14 with theedge card 396 first mating with theedge card opening 70 of theconnector 150A. Theconnector 390 has signal carrying contacts 395. Thelatch arms 382 are then aligned withalignment arms 78, theramps 388 in sliding engagement withsurfaces 84 ofalignment arms 78 until thelatch arms 382 are locked behindsurfaces 82 as shown in Figure 11. - The
face plate 400 may then be placed over thewall box 2face plate openings adaptors plug data connector 490 as shown in Figure 2. The assembly is also ready for reception of a data interface connector of the type disclosed in U.S.-A-4,193,654 and 4,501,459. - Hermaphroditic data connector 500 (Figure 15) when interconnected to
data interface assembly 200 interconnects like terminals inconnector 500 withterminals 214, and commons like shielding wings with shieldingwings 538 and shieldingwings 262. When thedata connector 500 is inserted the T-bar overlaps T-slot 326, and likewise the T-slot ofdata connector 500 overlaps T-bar 314. - Thus, the instant embodiment 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.
