- Data communication lines are installed within office buildings, or the like, much like the installation electrical power wiring, or telephone wire. Often new offices are modularly formed or new terminals are needed to compliment existing computer terminals. It is advantageous to have the ability to wire the data connectors at the facility without regard to the lengths of runs required in the cable lengths.
- the desired method is to run the cable through the walls or through channels in the flooring to dispose the ends of the shielded cable at the required locations. The ends of the shielded cables are then prepared and the data connectors installed.
- a first advantage of the present invention is that the premolded one piece boot provides an economic advantage to the user, over previous prior art connectors.
- the user can stock gross lengths of unprepared shielded cable, typically bought in rolls of hundreds of feet, and only terminate the shielded cable to data connectors when necessary. This method of stocking components is much easier and cost effective than stocking a large quantity of lengths of cable with preterminated data connectors at each end thereof.
- the present invention allows the unprepared cable to be fed through small openings in the flooring or the walls which is an imperative requirement for the new installation of any type of wiring. Feeding the cable through openings would not be possible with a cable preterminated to a data connector.

- identical shielded subassemblies 2 can either be used with a communication outlet 200, such as that shown in Figure 9, or can be used with the premolded boot 120 previously described.
- a typical installation of the preferred embodiment of the invention would include an outlet 200 connected to the outside of a wall, within an office building, with data communication cable similar to the shielded cable 180 within the wall or under the floor, and terminated, as previously described, to a shielded subassembly 2.
- the shielded subassembly 2 would then be latchably received to the back of the communication outlet 200, as shown in Figure 9.
- the data connector 4 having an identical shielded subassembly 2 as in the communication outlet 200, is then matably received with the front face of the outlet 200 to interconnect resilient contact portions 36 of like terminals 30.
- identical shielded subassemblies are required for either the data connector or the communication outlet 200, the component parts for the shielded subassembly can be easily stocked without a predetermined end to their use.
- the identical shielded subassemblies allow retrofitting of a previously assembled data connector into a communication outlet, or vice versa, a previously assembled communication outlet into a data connector.
- the wallplate 200 is shown as including a data connector interface 202 and a modular plug interface 280.

Description
- The invention relates to electrical connectors for use in terminating shielded multiconductor cables and more specifically to shielded local area network electrical connectors.
- U.S. Patent 4,501,459 discloses a local area network connector specifically intended for use in the data communications industry. These connectors can be employed in a closed loop data communications link in which various equipment such as computer terminals can be interconnected in a system. These connectors are specifically adapted for use in interconnecting numerous micro or mini computers in a computer network in an office environment. Connectors of this type have standard interface dimensions and configurations. These connectors must also be shielded to prevent spurious electrical signals and noise from affecting the signals in the network. These connectors also require a shunting capability since the conductors are part of a network and can be connected in series with other similar connectors. This shunting capability is necessary to prevent disruption of the network when an individual plug is not connected to external equipment.
- The structure and components of local area network connectors of this type is represented by the structure of the connector shown in U.S. Patent 4,501,459. These connectors include a plurality of spring metal terminals having insulation displacement wire barrels for establishing electrical connection with the individual conductors forming the multi conductor shielded cable. Terminals are positioned on a support housing and upper and lower shields can be positioned in surrounding relationship to the terminals and the support housing. Shield members are permanently attached to upper and lower cover members and the cover members are mated to both encapsulate the conductor and to common the upper and lower shields to the cable shielding.
- Similar data connectors of this type are shown in U. S. Patents 4,449,778; 4,508,415; 4,582,376; 4,602,833; 4,619,494; 4,653,825; 4,641,906; 4,671,599. U.S. Patent 4,653,825 in particular relates to a data connector which utilizes a housing slidably receivable over the internal housing subassembly. Although the data connector shown in U.S. Patent 4,653,825 provides an excellent interconnection for a shielded multiconductor cable in a local area network, the data connector is designed for assembly in a harness assembly plant. As the post molded grommet must be molded after the assembly thereof, the data connector cannot be field assembled, and the cable must be cut to specific lengths in the harness assembly plant.
- There exists within the industry a need for a low cost local area network connector of this general type which can be easily hand assembled at the end user's facility. The instant invention fills that need for a relatively lower cost, by providing a hand assembled connector which is suitable for use in a local area network in combination with prior art connectors of the type described herein.
- The invention consists in an electrical connector for interconnection to multiconductor data cable comprising an insulative housing including a terminal support platform and two side walls upstanding from the platform and forming an open upper face of the platform, a plurality of electrical terminals positioned along and supported by the terminal support platform, each of the terminals including a resilient contact portion for interconnection to like contact portions in a complementary electrical connector, and shielding means including first and second shield members assembled to the insulative housing, said first shield member including a base wall disposed adjacent the exterior of the terminal support floor, two sidewalls upstanding from the base wall and having upper edges which upstand higher than the sidewalls of the housing, and two contact portions extending from the front edge thereof which lie adjacent to the terminal support floor, and said second shield member including a plate portion having two shield contact portions extending from a front edge of the plate portion, the plate portion of the second shield member including at least one first tab member extending from each side edge of the plate portion, the first tab members engaging the upper edges of the first shield member sidewalls, thereby limiting the downward movement of the second shield member.

Theshield member 100 further includes arear wall portion 114 having asemicircular shield tail 116 extending from therear wall 114.Plate member 102 further compriseslocking lances 106, andtabs - With reference still to Figure 2, the
premolded boot 120 includes acentral body portion 122, aflexible portion 124 and alatching portion 126. Referring now to Figure 6A, the internal structure of the premolded boot generally includes acable receiving bore 158, acavity 156 and aconnector receiving cavity 128. Thecavity 156 is defined by aninner bore 160, while theconnector receiving cavity 128 is defined by anupper surface 148, alower surface 150 and sidewalls 162 (Figure 2). Theupper surface 148 includes a transversely extendingchannel 140 therein having aforward edge 142 while thelower surface 150 has a transversely extendingchannel 144 therein with aforward edge 146. Thelatching mechanism 126 generally comprises alatching extension 130 and alatching extension 132. The latchingextension 130 includes asingle latching projection 134 having end surfaces 135 (Figure 2). The latchingextension 132 includes two latchingprojections 136, the latching projections being spaced apart to define aslot 138 therebetween. The latchingprojections - With reference to Figure 2, the assembly further includes a
ferrule 170 havingsemicircular portions 172 and collapsible portions 174. Thedata connector 4, as shown in Figure 2, is for interconnection to a shielded cable shown generally as 180. The shieldedcable 180 includesouter insulation 182, a shieldingbraid 184,inner insulation 188 and individualinsulated conductors 186. An innermetallic ferrule 178 is profiled to be slidably received over theouter insulation 182. - To interconnect the shielded
cable 180 to the data connector of the instant invention, thehousing portion 5, of Figure 4, is first assembled. With the shorting bars 60 removed, theterminals 30 are slidably received inrespective channels 12 until latched in place. The shorting bars 60 are then inserted inrespective grooves 23, the shorting bars 60 contacting thecommoning foot 38 on alternate terminals to common alternate terminals when thedata connector 4 is in an unmated condition. It should be understood that to insert the shielded cable through thebore 158 of thepremolded boot 120, the shielded cable must be in an unprepared condition, whereas thecable 180, as shown in Figure 2, is shown in a prepared condition. Said another way, the cable must be left unstripped so that the blunt end alone is inserted into thebore 158, similar to threading a needle. With the shieldedcable 180 inserted through thebore 158 of theboot 120, the boot can be pulled back on the cable to allow room for preparation of the cable end. Prior to preparing the end of the shielded cable but subsequent to placing thepremolded boot 120 onto the cable, themetal ferrule 178 having an inner diameter substantially the same as the outer diameter of theinsulation 182 is slidably received over thecable 180. Also acollapsible ferrule 170 is slid over the end of the cable and is placed back upon the cable with the premolded boot for later use. - The end of the shielded cable can then be prepared by stripping a portion of the outer insulation from the end of the cable to expose a portion of the
shield 184. Theferrule 178 is then placed adjacent to the end of the stripped insulation and the exposed shieldingbraid 184 is dressed over theferrule 178, as shown in Figure 2. Theinner insulation 188 is then stripped to expose theinsulated conductors 186 and eachindividual wire 186 is placed in the stuffer cap through arespective slot 54, with the ends of thewire 186 extending into thebarrels 56 through theslot 58. Thestuffer cap 50 and theindividual wire 186 are then placed over theinsulative housing 5 such thatribs 52 on thestuffer cap 50 are aligned withchannels 22 in theinsulative housing 5, which in turn aligns the stuffer cap barrels 56 with the insulation displacement wire barrels 32 on theterminals 30. Thestuffer cap 50 is then pushed downwardly until each of theindividual conductors 186 is terminated within respective wire barrels 32 ofterminals 30. - The shielded
subassembly 2 is completed by installing theshield members insulative housing 5. Theshield member 70 is first inserted over thehousing 5 such thatwindows 84 in theshield 70 overlie theribs 20 of thehousing 5. This placesplate member 72 adjacent to thesurface 26 of the housing andshield members 90 adjacent to surface 28 of the housing. Furthermore, and as shown in Figure 5, as installed, therear wall 78 of the shield member lies adjacent to the rear of theconnector housing 5 to substantially shield thehousing member 5. This also placessemicircular shielding tail 76 in an overlying relationship with the dressedbraid 184, trapping the braid between theferrule 178 andsemicircular portion 76. Theshield member 100 is next installed by placing forward shieldmembers 110 through thewindows 8 of theconnector housing 5 such that theforward shield members 110 lie flush against the forward surfaces 24 and between therib 25. Theshield member 100 is latched in place by locking thetabs 104 into thewindows 86 of theshield member 70. As shown in Figure 3, thetabs 108 overlap the shield sidewalls 80 to keep thetabs 104 and thewindows 86 in a latched condition. - As installed, the
plate member 102 of theshield member 100 overlies theterminals 30 within theconnector housing 5. Therear wall 114 of theshield member 100 encloses the rear edge of theconnector housing 5 withedge 115 of the rear wall 174 substantially adjacent to edge 79 (Figure 5) ofrear wall 78 to totally enclose the connector housing. Also as installed, thesemicircular shield tail 116 overlies and is substantially adjacent to the dressed braid and thebackup ferrule 178. The previously installedferrule 170 can then be slid forwardly to overlie thesemicircular shield tails ferrule 170 can be crimped to a configuration as shown in Figure 3. The collapsible ferrule provides for a permanent electrical connection between the shielding components, that is, the shieldingbraid 184 is trapped between themetal backup ferrule 178 and between themetallic shield tails - With the
individual conductors 186 terminated to therespective terminals 30, and with the shieldedbraid 184 commoned to the shieldedsubassembly 2, the shieldedboot 120 can now be slid forwardly to encapsulate and insulate the shieldedsubassembly 2. Thepremolded boot 120 and the shieldedsubassembly 2 are pulled together until therear walls shield members shoulders premolded boot 120, as shown in Figure 6B. This disposes the crimp assembly of the collapsible ferrule within thecavity 156 and the shielded subassembly within thecavity 128. Thecavity 128 is closely toleranced to receive the shieldedsubassembly 2, that isshield plate members surfaces sidewalls 80 of theshield member 70 lie substantially flush with the inner sidewalls 162 of the premolded boot. As installed, the locking lances 74 and 106 are disposed within thetransverse channels surfaces - It should be understood that the assembly as previously described can be installed within the user's facility without any assembly equipment. At most, a pocket knife is required to strip the cable and a pair of pliers is required to push the stuffer cap down to terminate the insulated conductors. Data communication lines are installed within office buildings, or the like, much like the installation electrical power wiring, or telephone wire. Often new offices are modularly formed or new terminals are needed to compliment existing computer terminals. It is advantageous to have the ability to wire the data connectors at the facility without regard to the lengths of runs required in the cable lengths. When a new shielded cable is installed, the desired method is to run the cable through the walls or through channels in the flooring to dispose the ends of the shielded cable at the required locations. The ends of the shielded cables are then prepared and the data connectors installed.
- A first advantage of the present invention is that the premolded one piece boot provides an economic advantage to the user, over previous prior art connectors. Second, the user can stock gross lengths of unprepared shielded cable, typically bought in rolls of hundreds of feet, and only terminate the shielded cable to data connectors when necessary. This method of stocking components is much easier and cost effective than stocking a large quantity of lengths of cable with preterminated data connectors at each end thereof. Third, the present invention allows the unprepared cable to be fed through small openings in the flooring or the walls which is an imperative requirement for the new installation of any type of wiring. Feeding the cable through openings would not be possible with a cable preterminated to a data connector.
- Further advantages relate to the intermatability of the presently designed data connector. As assembled, the
data connector 4 is matable with ahermaphroditic data connector 300, as shown in Figures 7 and 8. Thedata connector 300 shown in Figure 9 is generally of the type disclosed in U. S. Patents 4,449,778; 4,501,459; 4,508,415; 4,582,376; and 4,602,833; and in U.S. Patent Application Serial Numbers 773,730; 830,904; and 823,134; the disclosures of which are incorporated herein by reference. - As shown in Figure 7, the data connector is also interconnectable with a
data connector 300. The latching mechanism of thedata connector 300 includes alatch plate 320 and alatch plate 322. The forward end of thelatch plate 320 includes a T-slot 302 defined byedges 304 andedges 306 defining a slot therebetween. A latchingsurface 308 is also defined within the T-slot 302. The latchingprojection 134 on thepremolded boot 120 has end edges 135. Thepremolded boot 120 is profiled such that, upon mating of the data connector of the instant invention with thedata connector 300, the latchingextension 130 is slidably received under the latchingplate 320 of thedata connector 300. This disposes the latchingprojection 134 within the T-slot 302 with theedges 135 of the latchingprojection 134 between the end surfaces 304 of the T-slot 302 and the latchingprojection 134 behind latchingsurface 308 of the T-slot 302. - Referring now to Figure 8, the T-
bar 310 is shown in greater detail. The T-bar 310 of thedata connector 300 generally includes abar portion 312 and anarm portion 314 interconnected to theplate portion 322. Thebar portion 312 and thearm portion 314 defines a latchingsurface 316 on the back side of thebar portion 312. The latchingprojections 136 on the data connector of the instant invention define aslot 138 therebetween. When in the mated position, the T-bar 310 of thedata connector 300 is latched with theprojections 136, such that thearm portion 314 is disposed within theslot 138 with the latchingsurface 316 of thebar portion 312 behind the latchingprojections 136. - Furthermore, identical shielded
subassemblies 2 can either be used with acommunication outlet 200, such as that shown in Figure 9, or can be used with thepremolded boot 120 previously described. A typical installation of the preferred embodiment of the invention would include anoutlet 200 connected to the outside of a wall, within an office building, with data communication cable similar to the shieldedcable 180 within the wall or under the floor, and terminated, as previously described, to a shieldedsubassembly 2. The shieldedsubassembly 2 would then be latchably received to the back of thecommunication outlet 200, as shown in Figure 9. Thedata connector 4, having an identical shieldedsubassembly 2 as in thecommunication outlet 200, is then matably received with the front face of theoutlet 200 to interconnectresilient contact portions 36 of liketerminals 30. Given that identical shielded subassemblies are required for either the data connector or thecommunication outlet 200, the component parts for the shielded subassembly can be easily stocked without a predetermined end to their use. Furthermore, the identical shielded subassemblies allow retrofitting of a previously assembled data connector into a communication outlet, or vice versa, a previously assembled communication outlet into a data connector. - Referring now to Figure 9, the outlet assembly of the instant invention, generally comprises a shielded
subassembly 2, anunshielded connector 290 and anoutlet wallplate 200, the shieldedsubassembly 2 and theunshielded connector 290 each being receivable into and out of the outlet wallplate 200 and being latchably attached therein. It should be noted that the shieldedsubassembly 2 is identical to that above described. - Referring again to Figure 9, the
wallplate 200 is shown as including adata connector interface 202 and amodular plug interface 280. Thewall outlet 200 is a one-piece molded housing and is used for interconnecting from the rear a shieldedsubassembly 2 and amodular jack 290. With reference now to Figure 10, thedata connector interface 202 is shown in greater detail. - The
interface 202 generally comprises ashroud member 204 forming a peripheral wall surrounding the data connection opening to partially insulate the electrical connection between the two mating electrical components. Theshroud member 204 defines an internalupper surface 212, alower surface 214 andside surfaces shroud 204 areback wall sections wallplate face 206. In between thewall portion edges 266 ofrear wall 216,edge 268 ofrear wall 250 and the upper 212 and lower 214 surfaces. This opening is defined to allow the entry from the rear of the shieldedsubassembly 2 as will be described in more detail subsequently. Extending from the upper 212 and lower 214 surfaces are latchingedges 260 which extend into the opening. - Also within the periphery of the
shroud member 204 is a T-bar member 220 and a T-slot member 240. The T-bar 220 and the T-slot 240 are profiled to simulate the T-bar and T-slot of the data connectors as previously described, for example in U. S. Patent 4,501,459. Referring first to the T-bar member 220, the member generally includes abar member 224 interconnected to theinternal surface 210 and to therear wall 216 via an integral moldedweb 222, as shown in Figures 10 and 11. As best shown in Figure 11, the rear surface of thebar 224 defines a latchingsurface 226 while the ends of thebar 224form end walls 228. As best shown in Figure 10, directly behind the latching surfaces 226 of thebar 224 and defined in therear wall 216 is a pair ofapertures 230 which extend through the wall and are generally defined by the retractable pins which define the latching surfaces 226 during the molding process. - Referring now to Figures 10 and 11, the detail of the T-slot will be described in greater detail. Referring first to Figure 12, the T-slot extends between
upper surface 212 andlower surface 214 and is integrally molded therein viawebs 254. The rear portion of the T-slot is integrally molded with theback wall portion 250 viaintegral portions 249. Theintegral web portions 254 defineinternal sidewalls 246 which extend from the outer edge of the web to therear wall 250. Theintegral web portions 249 each have anarm 242 extending therefrom towards the center of the interface. Each of the arms is spaced from each other as defined byend surfaces 244 which also define a slot therebetween. The rear edge of thearms 242 each define a latchingsurface 252. - Referring again to Figure 9, the assembly there shown further includes a latchable
modular jack 290 which generally includes a latchingstructure 292 having a latchingsurface 296, amodular plug interface 294 and an insulationdisplacement stuffer cap 298. Thewallplate 200, in turn, includes amodular plug interface 280 having anopening 282 which is normally covered by a spring loadeddoor 286. Referring now to Figure 13, the cross-sectional view through the modular jack interface clearly depicts the latching surfaces 284 disposed at the rear side of the wallplate behind theopening 282. - With the shielded subassembly assembled as previously described, the shielded
subassembly 2 is interconnectable into the opening from the rear side of thedata communication interface 202. Referring first to Figure 14, as installed thelatches 88 of theshield side walls 80 lock behind the latching surfaces 260 within the opening. Also as shown in Figure 15, as installed thelatches data connector 4, as illustrated in Figures 16 and 17. - As shown in Figure 18, the
outlet 200 is also interconnectable with adata connector 300. The latching mechanism of thedata connector 300 includeslatch plates latch plate 320 includes a T-bar 310 having latchingsurfaces 316 while the forward end of thelatch plate 322 includes a T-slot 302 having latching surfaces 308. As shown in Figure 18, thelatch plates web portions bar 310 is placed over the T-slot 240 and the T-slot 302 is placed under the T-bar 220.
