Definitions

  • 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.
  • U.S. Patent 4,653,825 in particular relates to a data connector which utilizes a housing slidably receivable over the internal housing subassembly.
  • 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.
  • the invention consists in an electrical connector for interconnection to a shielded cable, including an insulative housing, which houses a plurality of electrical terminals, shielding means substantially surrounding the housing, and an insulative cover means for the shielding means, the housing including a terminal support floor and sidewalls extending upwardly therefrom, the terminal support floor including terminal receiving means for receipt of the terminals, each said terminal having a resilient contact portion and a wire termination means; the connector being characterized in that the insulative cover means is profiled as a premolded insulative boot means slidably receivable over the insulative housing and the shielding means and at least partially encapsulating said insulative housing and said shielding means therein.

  • the resilient contact portion 36 is looped back upon itself and spaced above the terminal support floor.
  • the resilient contact portion 36 is disposed at the front mating face of the housing 5 for overlapping interconnection with like terminals, the two resilient contact portions of mating connectors contacting each other to deflect respective resilient contact portions towards the blade portion of respective terminals.

  • the shield member 100 further includes a rear wall portion 114 having a semicircular shield tail 116 extending from the rear wall 114.
  • Plate member 102 further comprises locking lances 106, and tabs 104 and 108 extending from the side edges thereof.
  • the premolded boot 120 includes a central body portion 122, a flexible portion 124 and a latching portion 126.
  • the internal structure of the premolded boot generally includes a cable receiving bore 158, a cavity 156 and a connector receiving cavity 128.
  • the cavity 156 is defined by an inner bore 160
  • the connector receiving cavity 128 is defined by an upper surface 148, a lower surface 150 and sidewalls 162 ( Figure 2).
  • the upper surface 148 includes a transversely extending channel 140 therein having a forward edge 142 while the lower surface 150 has a transversely extending channel 144 therein with a forward edge 146.
  • the latching mechanism 126 generally comprises a latching extension 130 and a latching extension 132.
  • the latching extension 130 includes a single latching projection 134 having end surfaces 135 ( Figure 2).
  • the latching extension 132 includes two latching projections 136, the latching projections being spaced apart to define a slot 138 therebetween.
  • the latching projections 134, 136 are defined as raised detents, the use and functioning of which will be described in greater detail herein.
  • the assembly further includes a ferrule 170 having semicircular portions 172 and collapsible portions 174.
  • the data connector 4 as shown in Figure 2, is for interconnection to a shielded cable shown generally as 180.
  • the shielded cable 180 includes outer insulation 182, a shielding braid 184, inner insulation 188 and individual insulated conductors 186.
  • An inner metallic ferrule 178 is profiled to be slidably received over the outer insulation 182.
  • the housing portion 5, of Figure 4 is first assembled. With the shorting bars 60 removed, the terminals 30 are slidably received in respective channels 12 until latched in place. The shorting bars 60 are then inserted in respective grooves 23, the shorting bars 60 contacting the commoning foot 38 on alternate terminals to common alternate terminals when the data connector 4 is in an unmated condition. It should be understood that to insert the shielded cable through the bore 158 of the premolded boot 120, the shielded cable must be in an unprepared condition, whereas the cable 180, as shown in Figure 2, is shown in a prepared condition.
  • the cable must be left unstripped so that the blunt end alone is inserted into the bore 158, similar to threading a needle.
  • the boot With the shielded cable 180 inserted through the bore 158 of the boot 120, the boot can be pulled back on the cable to allow room for preparation of the cable end.
  • the metal ferrule 178 Prior to preparing the end of the shielded cable but subsequent to placing the premolded boot 120 onto the cable, the metal ferrule 178 having an inner diameter substantially the same as the outer diameter of the insulation 182 is slidably received over the cable 180. Also a collapsible 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.
  • the ferrule 178 is then placed adjacent to the end of the stripped insulation and the exposed shielding braid 184 is dressed over the ferrule 178, as shown in Figure 2.
  • the inner insulation 188 is then stripped to expose the insulated conductors 186 and each individual wire 186 is placed in the stuffer cap through a respective slot 54, with the ends of the wire 186 extending into the barrels 56 through the slot 58.
  • the stuffer cap 50 and the individual wire 186 are then placed over the insulative housing 5 such that ribs 52 on the stuffer cap 50 are aligned with channels 22 in the insulative housing 5, which in turn aligns the stuffer cap barrels 56 with the insulation displacement wire barrels 32 on the terminals 30.
  • the stuffer cap 50 is then pushed downwardly until each of the individual conductors 186 is terminated within respective wire barrels 32 of terminals 30.
  • the shielded subassembly 2 is completed by installing the shield members 70 and 100 to the insulative housing 5.
  • the shield member 70 is first inserted over the housing 5 such that windows 84 in the shield 70 overlie the ribs 20 of the housing 5.
  • the rear wall 78 of the shield member lies adjacent to the rear of the connector housing 5 to substantially shield the housing member 5.
  • This also places semicircular shielding tail 76 in an overlying relationship with the dressed braid 184, trapping the braid between the ferrule 178 and semicircular portion 76.
  • the shield member 100 is next installed by placing forward shield members 110 through the windows 8 of the connector housing 5 such that the forward shield members 110 lie flush against the forward surfaces 24 and between the rib 25.
  • the shield member 100 is latched in place by locking the tabs 104 into the windows 86 of the shield member 70. As shown in Figure 3, the tabs 108 overlap the shield sidewalls 80 to keep the tabs 104 and the windows 86 in a latched condition.
  • the plate member 102 of the shield member 100 overlies the terminals 30 within the connector housing 5.
  • the rear wall 114 of the shield member 100 encloses the rear edge of the connector housing 5 with edge 115 of the rear wall 114 substantially adjacent to edge 79 ( Figure 5) of rear wall 78 to totally enclose the connector housing.
  • the semicircular shield tail 116 overlies and is substantially adjacent to the dressed braid and the backup ferrule 178.
  • the previously installed ferrule 170 can then be slid forwardly to overlie the semicircular shield tails 76 and 116, and the 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 shielding braid 184 is trapped between the metal backup ferrule 178 and between the metallic shield tails 76 and 116.
  • the shielded boot 120 can now be slid forwardly to encapsulate and insulate the shielded subassembly 2.
  • the premolded boot 120 and the shielded subassembly 2 are pulled together until the rear walls 78, 114 of the shield members 70 and 100, respectively, abut the shoulders 152 and 154, respectively, within the premolded boot 120, as shown in Figure 6B. This disposes the crimp assembly of the collapsible ferrule within the cavity 156 and the shielded subassembly within the cavity 128.
  • the cavity 128 is closely toleranced to receive the shielded subassembly 2, that is shield plate members 72 and 102 lie substantially flush with surfaces 148 and 150, respectively. Furthermore, the sidewalls 80 of the shield 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 the transverse channels 140 and 144, respectively, and are latched against surfaces 142 and 146, respectively.
  • 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.
  • 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.
