Definitions

  • This invention relates to solderless wire connectors which, although useful in connecting single wires, are particularly adapted for use with bonded pairs of insulated wires (twinned wires or wire pairs) wherein the two conductors are held. in separated side-by-side parallel relationship by means of a unitary plastic insulating cover surrounding both wires and having a figure 8 or twin-circle cross section such as is commercially available under the trade designation Unipair conductor.
  • These wire pairs come in various wire sizes, e.g. from No. 28 to No. 22 B & S gauge, and ordinarily with a polyethylene or similar plastic insulating covering.
  • FIG. 5 is a sectional elevation taken approximately along the section 5-5 of FIG. 2;
  • the cap 12 in FIG. 3 is seen inverted from its normal position atop jacket 11 as shown in FIG. 1.
  • the thus exposed inner surface is provided with sharp-edged ridges 41, 42 which fit snugly between the end walls and within grooves l7, 18 respectively of jacket 11.
  • Transversely of the ridges are located contact members 43, 44, the member 43 being further shown in FIG. 4.
  • Each contact member consists of two resilient doubly pointed slotted or bifurcate contact elements 45, 46 joined by a connecting bridge 47 which is embedded in the plastic cap and is firmly retained by the sharp projecting corners 48, 49.
  • the slots 50, 51 of contact member 43 are aligned with the position of the wire ends on the wire-supporting surfaces 25, 27 when the cap is placed on the jacket 11. Similar considerations hold for contact member 44.
  • Elongate ridges 54, 55 extend outwardly from the side edges of the cap, and analogous extensions may if desired be. provided centrally of the end edges. All four edges of the cap are slightly flared outwardly to form a broken peripheral peak line 56 of maximum diameter. In the open position shown in FIG. I, the ridges 54, 55 fit below the peak line 39 ofjacket I1 and retain the cap against accidental displacement. The ends of the ridges 41, 42 fit against the end walls of the cap to further stabilize the connector in the open position.
