Definitions

  • This invention relates to an electric connector assembly of the kind in which the electric contacts and associated conductor terminals are mounted in a preformed body of electrically insulating material, the conductors of a length of flexible insulated multi-conductor cable are electrically connected to appropriate terminals of the connector, and a moulded plug body of electrically insulating material wholly or partially encapsulates the preformed body and is permanently bonded to the insulating covering of a part of the length of cable.
  • Electric connector assemblies of this kind will hereinafter, for convenience, be referred to as "of the kind described”.
  • the invention is concerned both with electric connector assemblies of the kind described in which at least one of the electric contacts is a pin protruding from the rear face of the preformed body and in which at least one of the electric contacts is a socket within the preformed body.
  • an electric connector assembly of the kind in which the electric contacts and associated conductor terminals are mounted in a preformed body of electrically insulating material, the conductors of a length of flexible insulated multi-conductor cable are electrically connected to appropriate terminals of the connector, and a moulded plug body of electrically insulating material wholly or partially encapsulates the preformed body and is permanently bonded to the insulating covering of a part of the length of the cable, wherein the preformed body comprises, upstanding from its front face, a wall which surrounds at least the holes and recesses in the preformed body associated with the line and neutral electric contacts and which has a gap or aperture therethrough for entry of the cable conductors; and wherein the space bounded by said wall is closed by a preformed cap of electrically insulating material to form an enclosure housing at least the line and neutral terminals.
  • the wall upstanding from the front face of the preformed body surrounds the holes and recesses associated with all of the electric contacts, including, if present, any hole or recess for accommodating a carrier of electric contacts for a cartridge fuse.
  • the preformed cap is preferably of an electrically insulating material that is substantially harder than the moulded insulating material of the plug body.
  • the cap may be a snap fit over or in the open end of the enclosure bounded by the upstanding wall or it may be in sliding engagement with the wall. In the former case a side-edge of the cap may be hinged to the upper edge of a part of the upstanding wall by a web of insulating material integral with the wall and the cap.
  • the enclosure may serve to prevent the insulating material of the plug body from coming into contact with the electric sockets and their associated conductor terminals, thereby preventing moulded insulating material from forming an obstruction in the sockets relative to the preformed body to facilitate insertion of pins in the sockets.
  • the wall and/or cap of the enclosure may have one or more than one aperture through which insulating material of the plug body can flow to encapsulate the conductor terminals and inner ends of the pins.
  • a number of mutually spaced holes are provided in the upstanding wall immediately adjacent the front face of the preformed body.
  • the moulded plug body is of urea or polyester
  • the preformed body and the preformed cap are of nylon or polyester.
  • the conductors of the flexible cable may be electrically connected to the conductor terminals in any convenient manner, a crimped connection being preferred.
  • the invention also includes an improved method of manufacturing an electric connector assembly as hereinbefore described, which method comprises effecting the electrical and/or mechanical connections between the electric contacts and their associated conductor terminals and the electrical connections between the cable conductors and the conductor terminals; introducing all the electric contacts and their associated conductor terminals, with the cable conductors electrically connected thereto, into holes and recesses in the front face of the preformed body, said preformed body having, upstanding from its front face, a wall which surrounds at least the holes and recesses in the preformed body associated with the line and neutral electric contacts and which has a gap or aperture therethrough for entry of the cable conductors; closing the space bounded by said wall by a preformed cap of electrically insulating material to form an enclosure housing at least the line and neutral conductor terminals; and moulding therearound electrically insulating material to form a moulded plug body which wholly or partially encapsulates the preformed body and said enclosure and which is bonded to the insulating covering of a part of the length of the
  • the plug body is preferably moulded in one operation.
  • the plug body may be moulded in two or more operations, each moulding wholly or partially encapsulating the preformed body and said enclosure and/or the or each previous moulding, and bonding together.
  • the preformed body is made of moulded plastics material and comprises a base 1 having holes 2 and recesses in its front face 3 for the reception of the plug pins and their associated conductor terminals and, surrounding the holes and recesses, a wall 4 which upstands from the front face of the base and which has a gap 5 for introduction of the cable conductors.
  • the space bounded by the wall 4 is closed by a preformed cap 6 which slides in a groove 7 on the inner surface of the wall and which has, at one end, a flange'8 with a gap 9 that ' co-operates with the gap 5 to form the cable entry aperture.
  • the enclosure is closed by the cap 6 and electrically insulating material is moulded therearound to form a moulded plug body which encapsulates the preformed body and the enclosure and which is bonded to the insulating covering of a part of the length of the flexible cable.
  • the second form of preformed body is made of moulded plastics material and comprises a base 11 having holes 12 and recesses in its front face 13 for the reception of plug pins and their associated conductor terminals and, surrounding the holes and.recesses, a wall 14 which upstands from the front face of the base and which has a gap 15 for introduction of the cable conductors.
  • the space bounded by the wall 14 is closed by a preformed lid 16 which is hinged to the wall 14 by an integral web 17 and which has a depending peripheral wall 18 with a gap 19 that co-operates with the gap 15 to form the cable entry aperture.
  • the walls 4 and 14 may have, adjacent the front face of the base, spaced apertures for entry of material into the space enclosed by the enclosure.
  • the upstanding wall may surround only the holes and recesses associated with the neutral and line electric contacts, so that the earth contact terminal remains outside the enclosure defined by the walls and the preformed cap.
