Definitions

  • a male and female connector each having a wire connecting side and a mating side, oppositely directed to the wire connecting side, are clamped together with their wire connecting sides adjacent and wire connecting portions of corresponding terminals in alignment, the mating sides being oppositely directed.
  • an electrical connector assembly for multiple wire cable having a male and female connector pair with terminals thereof having aligned wire connecting portions and oppositely projecting mating portions adjacent mating sides of said connector pair; is characterised by first and second metal intermated shells fully enclosing said connector pairto shield them and having a first opening encircled by a first flange exposing a first mating side of one of said pair of connectors, the flange extending beyond the first mating side, and a second opening encircled by a second flange exposing a second mating side of-the other of said connectors, the second flange extending beyond the second mating side, ends of said shells defining between them a cable entrance for wires of a multiple wire cable, connected to said pair of connectors and fastening means extending through said intermated shells to connect together, plural, stacked pairs of intermated shells, and wherein the first flange of said pair of mating connectors will mate with the second flange of another
  • Connector assemblies of the invention can provide a completely shielded tapped connection to two or more coaxial cables and may be readily mechanically connected together on site, and each pair of mating connectors can mate with two other such pairs of mating connectors.
  • Each shielding shell can be cast as a unit, since the cable entrance is defined by the shells themselves.
  • the fastener means includes a plurality of cap screws extending through aligned openings in the shells and each having a screw threaded shank end portion and ⁇ ⁇ ompIemen- tarily screw threaded head, the shank end portion of each cap screw projecting outwardly of the shells and engaging in the screw threaded head of a cap screw of said other pair of connectors, whereby a plurality of connector assemblies are interlocked together.
  • These cap screws can all be identical with one another, so that both stocking and the assembly of a stack of connector assemblies are simplified.
  • US-A-3,056,942 discloses the use of cap screws for securing only two connectors together. A plurality of different kinds of screws of different dimensions are employed.
  • a pair of wire clasping members each having a hasp at one end and at the other end a latch, are latched together about the abutting wire connecting sides of the pair of mating connectors to provide strain relief for the wires, the clasping members cooperating to hold the wires in mutually aligned channels formed in said wire connecting sides, the surface of each said member being rounded to prevent pinching damage to the wires and an undercut channel extending along each clasping member providing clearance for the corresponding wires.
  • the connector assembly 1 is for effecting shielded connection to individual wires 4 of a coaxial cable 2 which wires are surrounded by a shield 6 of metal braid which is contained within an outer jacket 8 of plastics material.
  • the wires 4 are connected to corresponding electrical terminals in each of two connectors described in United States Patent Specification No. 3,760,335, one connector being a male or plug connector 10, and the other being a female or receptable connector 12, clamped together in back-to-back relationship.
  • the wires 4 are connected to the terminals of the plug connector 10 and receptacle connector 12 using the technique disclosed in United States Patent Specification No. 4,032,211.
  • the plug connector has a wire connecting side 10A abutting a wire connecting side 12A of the receptacle connector 12.
  • Each side 10A and 12 is provided with two rows of mutually aligned wire receiving channels 14.
  • Electrical terminals of the type disclosed in United States Patent Specification No. 3,760,335 have wire connecting portions located in the channels 14 of each connector and these wire connecting portions will penetrate the insulation of a wire when inserted into a channel, and establish electrical contact with the conductive core of the wire.
  • the wires 4 are divided into two groups, 4A and 4B distributed along perspective parallel rows of the channels 14 and connected to respective rows of electrical terminals therein.
  • the terminated wires 4A and 4B are then covered by a pair of clasps 16 each moulded in one piece from plastics material and of sufficient length to cover the opposed wire- connecting sides 10 and 12A.
  • Undercut channels 18 are formed along each clasp 16 to provide a clearance for corresponding wires.
  • the surface of each clasp is rounded to prevent pinching damage to any of the wires.
  • One end of each clasp 16 is provided with a latching projection 19, engageable in an opening 23 in a hasp 21 on the other end of each clasp to secure the clasps together thereby to hold the wires more securely in the channels preventing inadvertent disconnection from the electrical terminals.
  • the connectors 10 and 12 further comprise a female or receptacle mating side 12B oppositely directed to a male or plug mating side 10B.
  • a flange 12C and 10C on the receptacle and plug respectively separate the mating sides from the wire receiving sides 12A and 10A.
  • the peripheries of the flanges 12C and 10C are reduced for compactness, and to fit within the confines of corresponding cast metal half-shells 20 and 22, described below.
  • the half-shells 20 and 22 are formed with rearwardly facing cavities 24 and 48 receiving the connectors 10 and 12, respectively.
  • Side walls 32 and 34 merge with thickened end walls 36, 58 and 38 provided with threaded bores 68.
  • Hemi-cylindrical cable lead-out openings 42 and 56, respectively, of stepped diameter are provided in the ends 36 and 58 and are formed with mutually aligned spaced apart ribs 44 and 60, respectively, and semi-cylindrical grooves 46 and 62.
  • the grooves 46 and 62 are in mutual alignment to receive an 0-ring 64 which tightly grips the jacket 8 of the cable 2, and is installed prior to connecting the wires 4 to the connectors 10 and 12.
  • the ribs 44 and 60 are clamped against the shield 6 to establish a good mechanical and electrical connection therewith.
  • the flanges 10C and 12C seat against the bottom walls 26 and 50 respectively, with the plug and receptacle mating sides 10B and 12B projecting into the openings 28 and 52 encircled by the flanges 30 and 54 respectively. Screws 66 passing through bores 40 engage threaded bores 68 connecting the shells 22 and 24 together.
  • elongate cap screws 70 pass through aligned openings 72 in the shell 20, 74 in the flange 1 OC, 76 in the flange 12C and 78 in the shell 22.
  • Each cap screw 70 includes an enlarged threaded shank end 80 which projects outwardly of the shell 22.
  • the ends 80 may engage complementary screwheads of another set of cap screws 70 which are assembled to another connector, allowing a plurality of connector assemblies 1 to be stacked and interlocked together, whereby the cables 2 may have their wires 4 electrically coupled together.
  • the half-shell flange 54 fits into the half-shell flange 30 in mating relation.
  • the receptacle mating side 12A intermates with a plug mating face 10B of the other connector.
