Definitions

  • the subject invention relates to an improved shielded data connector for use in local area network connections.
  • U.S. Patent 4,501,459 discloses a local area network connector specifically 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 micro computer network in an office environment. Connectors of this type have standard interface dimensions and configurations. These connectors must also be shielded to prevent the 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 a 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 connectors shown in the before mentioned 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 cover the upper and lower shields to the cable shielding.

  • the side plate portions 169 fit inside the sidewalls 134, into the recesses 19 of housing 4 to cover the shield windows created by the latches.
  • the resilient contact member 210 extends above the top surface of the stuffer cap, thus downward movement of the upper shield member 160 into its fully locked position, brings the upper plate portion 162 into ground contact with the contact member 212 on the cross talk shield 200.
  • the contact portions 36 of contacts 30 are substantially shielded against cross talk along their length, and their terminal barrel portions 35 as well as the signal pairs are prevented from cross talk by the cross talk shield member 200.
  • the assembly can be completed by crimping the arms 154 on the lower shield member to bring the shield arms into a crimp condition with the shielding braid of the shielded cable, which also commons the cross talk shield members 220 and 200 to the shielding braid.
  • the shielded sub-assembly as described above is then insertable into the housing member 70 ( Figures 5 and 6) through the rear side thereof until the housing 4 abuts the forward lip 85, whereupon the latches 142 are snapped in place within respective apertures 84.
  • strain relief member 110 ( Figures 27, 28) is then assembled over the shielded cable and together with assembled support members 95 ( Figures 7-9) are moved into a fully locked position where latch 106 engages in the window 83 of the housing member 70 to provide a strain relief to the cable as well as retain the shielded sub-assembly inside the housing 4.

  • stuffer cap 522 includes a generally centrally placed slot 622.
  • Slot 622 is placed between central barrel receiving portions of stuffer cap 522, generally proximate the areas 624 and 626. These barrel receiving portions are, however, electrically isolated, through the body of stuffer cap 522, from slot 622.
  • Central shield 524 is a conductive member, preferably formed of sheet metal.
  • Central shield 524 includes a front portion 628, which is separated from a central portion 630, having a greater vertical dimension, by a notch 632.
  • Notch 632 is configured to fit over a rear web 634 extending across slot 622 in stuffer cap 522.
  • Front portion 628 of central shield 524 is configured to extend proximate the entire vertical dimension of stuffer cap 522, when notch 632 engages web 634.
  • Extending above a generally central portion of central shield 524 are a plurality of generally resilient tabs 636.
  • Central shield 524, including tabs 636, is configured such that when connector 500 is assembled, tabs 636 will make mechanical and electrical contact with the lower side of upper shield 516, and the lower surface of central portion 630 will extend proximate the rear surface of terminal platform 540 and proximate lower shield 518.
  • shield 524 includes a rear "rudder" portion 638, which extends from central portion 630, but which is flexibly arranged through upper and lower separation notches 640 and 642.
  • the flexible attachment of rudder portion 638 to central portion 630 facilitates the bending, and resulting variable placement, of rudder portion 638 in any desired orientation relative to the termination of cable 526 in connector 500. This facilitates maintaining central shield 524 between pairs of signal carrying conductors 528, 530 regardless of the location at which cable 526 terminates in connector 500 (i.e., on a side, as depicted in Fig. 44, or axially, as generally depicted in Fig. 45.)
  • twisted pair conductors 528 and 530 extend beyond braided sheath 532 to facilitate their termination.
  • Central shield 524 extends between the pairs of conductors to provide a ground potential shield therebetween to minimize cross-talk between the conductors.
  • the engagement of tabs 636 with upper shield 516 serves to continue the ground potential shield of braided sheath 532 not only through the connector enclosure as formed by upper shield 516 and lower shield 518, but also to essentially surround each conductor pair within a ground potential enclosure through the interaction of central shield 524 with upper shield 516.
  • the extension of front portion 128 of central shield 524 through stuffer cap 522 continues this enclosure of each conductor pair through the complete termination of the pair at the barrel portion 565 of each terminal.
  • terminal housing 520 each include a forwardly extending base portion 654 which is reversely bent proximate a forward extent 656 to form a resilient contact tongue 658.
  • terminal housing 520 includes a central slot 650 extending between the base portions 654 of terminal end contact portions 562.
  • Slot 650 serves to establish an air gap between the terminals associated with each conductive pair, and to thereby reduce dielectric coupling between terminals. This reduction in dielectric coupling serves to further reduce signal cross-talk between the contact portions.
  • Slot 650 may be extended rearwardly virtually any desired distance which is consistent with the strength of the material utilized for terminal housing 520 and the strength requirements for the connector. Preferably, slot 650 will extend rearwardly as close as possible to the forward most extension of central shield 524.
