Definitions

  • the device of the present invention generally relates to electrical connectors and, more particularly although not exclusively, to electrical connectors for electrically interconnecting or splicing a plurality of low voltage coaxial cables.
  • US ⁇ A ⁇ 3,543,222 describes a method and apparatus for coupling to a coaxial cable involving drilling a hole in the cable to penetrate the outer conductor but not the inner conductor and then extending a forked electrical contact through the insulation separating the outer and inner conductors into gripping contact with the inner conductor to couple the cable, the electrical connection to the outer conductor being made directly by a further contact inserted in a similar hole.
  • the present invention proceeds from GB-A--1,013,499 which discloses an electrical connector for electrically interconnecting a plurality of coaxial cables including first means for electrically interconnecting the outer conductors of said plurality of coaxial cables through a short circuit electrical path, said first means comprising a first plurality of electrically interconnected contacts adapted to physically and electrically contact the outer conductors of said plurality of coaxial cables and second means for electrically interconnecting the inner conductors of said plurality of coaxial cables through a short circuit electrical path, said second means comprising a second plurality of electrically interconnected contacts adapted to physically and electrically contact the inner conductors of said plurality of electrical cables and is characterized in that said first means comprises an integrally formed first terminal member having a plurality of first end plate portions including insulation displacement slot means constituting said first plurality of electrically interconnected contacts, in that said second means comprises a second terminal member having a plurality of second end plate portions including insulation displacement slot means constituting said second plurality of electrically interconnected contacts, and
  • an electrical connector 20 which may be referred to as a mass termination connector, electrically interconnects or splices a plurality of three low voltage coaxial cables 22, 24 and 26 capable of transmitting high frequency, low power energy.
  • Each coaxial cable 22, 24 and 26 (Fig. 2) includes a central or current carrying conductor 28; an inner dielectric insulating layer 30; an outer conductor or metallic shield 32, typically formed as metallic braiding; and an outer dielectric insulating layer, jacket or sheath 34.
  • Each coaxial cable 22, 24 and 26 may be prepared for interconnection by the electrical connector 20 by baring and shaping an elongated portion 36 (Fig. 3) of the inner insulating layer 30.
  • the electrical connector 20 includes a generally T-shaped, molded, electrically insulating cover 40 (Fig. 4) formed from a suitable dielectric material that circumscribes or defines the interior of the electrical connector 20 when disposed over a base 42 of the electrical connector 20.
  • the cover 40 includes a plurality of three, elongated, generally U-shaped slots or openings 44 for the receipt of the cables 22, 24 and 26.
  • An electrically conductive metallic shield connecting terminal member 46 is fixedly secured in the cover 40 and includes a plurality of three, downwardly extending end plate positions including insulation displacement slot means forming insulation piercing contacts 48 for physically and electrically contacting and for electrically interconnecting the metallic shields 32 of the cables 22, 24 and 26.
  • the insulation displacement slot means of the contacts 48 include laterally spaced apart, exposed knife edges 50 (Fig. 5) extending inwardly into the slots 44.
  • the knife edges 50 cut through the outer insulating jackets 34 and physically and electrically contact the metallic shields 32 of the cables 22, 24 and 26 en masse (Figs. 5 and 6).
  • the shield connecting terminal member 46 also includes a plurality of three, elongated, interconnected, metallic leads 52 (Figs. 1 and 4) electrically interconnecting the three spaced apart contacts 48 and thus the three metallic shields 32 of the cables 22, 24 and 26.
  • the contacts 48 and the leads 52 comprise an integrally formed metallic strip.
  • the terminal member 46 may be formed in a desired configuration, is placed, prior to a molding operation, in a mold used to form the cover 40. In this manner, the cover 40 and the terminal member 46 may be formed as a single component part of the electrical connector 20.
  • the base 42 of the electrical connector 20 includes a generally T-shaped, electrically insulating substrate 60 (Fig. 7).
  • the substrate 60 includes a plurality of three, integrally formed, pairs of spaced apart protuberances or pedestal portions 62 extending upwardly from the inner surface of the base.
  • One of a plurality of three, upwardly extending end plate portions including insulation displacement slot means forming insulation piercing contacts 64 of an electrically conductive central conductor connecting terminal member 65 is supported by and mounted between each pair of pedestal portions 62.
  • Each contact 64 includes a pair of laterally spaced apart, converging knife edges 66 for cutting through the elongated portion 36 of the inner insulating layer 30 and for physically and electrically contacting the central conductor 28 of the cable 22, 24 or 26 (Figs. 6 and 8).
  • the central conductor connecting terminal member 65 also includes a plurality of elongated, interconnected, metallic leads or strips 68, secured to the substrate 60 by any suitable means, for electrically interconnecting the three contacts 64 and thus the central conductors 28 of the cables 22, 24 and 26 through a short circuit electrical path.
  • a plurality of two or more of the cables 22, 24 and 26 may be electrically interconnected by means of the electrical connector 20 in accordance with the following method. Initially, each cable 22, 24 and 26 is prepared as depicted in Fig.
  • the elongated portion 36 of the inner insulating layer 30 is bared by removing an elongated portion of the outer jacket 34 and a corresponding elongated portion of the metallic shield 32. Subsequently, the elongated portion 36 of the inner insulating layer 30 may be shaped, if desired, to facilitate its receipt on the contact 64 between the pair of pedestal portions 62 (Fig. 7 and 8) and to reduce the amount of effort required to cut through the inner insulating layer 30 in order to physically contact the central conductor 28. For example, the inner insulating layer 30 may be cut to form a plurality of two, generally parallel, spaced apart, flat or planar surfaces 70 (Fig. 3).
  • each elongated portion 36 of the cables 22, 24 and 26 (if all three cables 22, 24 and 26 are to be interconnected) is disposed fully in contact with the insulation piercing contact 64 (Fig. 8) such that the center conductor 28 is in physical and electrical contact with the converging knife edges 66.
  • the cover 40 may then be placed over the base 42 so that the cables 22, 24 and 26 are received in the slots 44.
  • the cover 40 is pressed downwardly in a mass termination operation until the cables 22, 24 and 26 are fully received within the slots 44, in which condition the knife edges 50 will have cut through the outer jackets 34 to physically and electrically contact the metallic shields 32 of the cables 22, 24 and 26.
  • the cover 40 and the base 42 may be configured to interlock, for example, by a snap fit between the cover 40 and the base 42, to maintain the cover 40 in secure engagement with the base 42.
  • the coaxial cables 22, 24 and 26 may be easily, quickly and reliably electrically interconnected.
