Definitions

  • an electrical connector comprising an insulating housing which has been moulded in one piece from insulating plastics material and which has a row of terminal receiving cavities opening into a wire receiving face of the housing, the cavities being separated from one another by insulating barrier walls, electrical terminals being received in the cavities, each terminal comprising first and second parallel metal plates having a wire-receiving slot adjacent to the wire-receiving face, the slot extending away from the wire receiving face but opening there towards so that a wire can be moved laterally of its longitudinal axis, towards the wire receiving face and into the slot so as electrically to connect the wire to the terminal.
  • the terminals are all discrete, being insulated from one another by the barrier walls. In some applications of such connectors it may be required that a group of the terminals be employed commonly to connect, electrically, a group of wires. In the case of either of these known connectors, commoning connections between the terminals of a selected group could not be provided without such connections being exposed to accidental electrical contact, and indeed there is no suggestion in either of the documents cited above, that any of the terminals should be commonly connected.
  • the present invention proceeds from the realisation that where the terminals of a group of terminals of a connector are to be electrically connected in common, the terminals should nevertheless be protected against accidental electrical contact and that, at the same time, it should be readily determinable by inspection which group of wires is commonly connected.
  • an electrical connector as defined in the first paragraph of this specification is characterised in that the first metal plates of the terminals are connected together, to provide a group of terminals, by means of a flexible common carrier strip which is formed integrally with each first metal plate, the flexible carrier strip being remote from the wire receiving slots of the terminals and being received in slots in the barrier walls which open into the wire receiving face of the housing, in such a way that the group of terminals is substantially enclosed in the housing, the number of the terminals being less than the number of the cavities in the housing and a vacant cavity being provided immediately adjacent to an end of the group of terminals, to indicate the extent of the terminal group which group is of a predetermined length.
  • a connector according to the invention that the group of terminals, which is cut from a reeled supply of terminal strip, can readily be assembled to the housing by automated methods usual in the art, the carrier strip by which the reeled terminals are joined, serving at the same time as a commoning strip for the group of terminals and being received in the slots in the barrier walls so as to be protected against accidental electrical contact. Since the pressure of the carrier strip cannot readily be detected by inspection the indicating function of the vacant cavity is of considerable value.
  • the connector includes a housing 11 moulded in one piece from insulating plastics material with a row of terminal-receiving cavities 12 opening to a wire-receiving face of the housing. Adjacent cavities are separated from each other by insulating barrier walls 13, each barrier wall being formed with a slot 14 extending away from the wire-receiving face for the entire length of the cavity.
  • the cavities have respective pairs of opposed side walls 15 and 16, formed with wire-receiving slots 17 and 18, respectively, which extend away from the mating face for a short distance into the side walls.
  • Strengthening ribs 19 extend along side walls 15 away from the wire-receiving face in parallel relation and under a base wall of the cavities.
  • Wire-trapping detents 22 are provided on the ends of the ribs 19 adjacent the wire-receiving face.
  • Parallel ribs 21 extend for a short distance along a lateral extension of the side wall 16 and are provided with similar wire-trapping detents 23 at ends adjacent the wire-receiving face.
  • a locking shoulder 24 is formed in each side wall 15 by a mould core pin and oppositely facing terminal supporting shoulders 25 are provided in each barrier wall.
  • Mounting feet 25 are provided at opposite ends of the housing.
  • the terminal strip is stamped and formed from sheet metal and comprises a row of wire-connecting portions extending in the same direction from a flexible carrier strip 35 to which they are integrally joined.
  • Each wire-connecting portion comprises a metal strip reversely bent to provide parallel metal plates 31 and 32 connected by a bight, a wire-receiving slot 33 extending through the bight into each plate.
  • the plate 32 is provided at a free end with a stabilising foot 34 of reduced width which extends towards the plate 31.
  • a locking tongue 36 is struck from each of the plates 31.
  • a predetermined length of terminal strip is severed from a reeled supply and inserted into the housing through the wire-receiving face until each locking tongue 36 springs behind a respective shoulder 24 and the free ends of side walls 35 abut the bases of the cavities.
  • the carrier strip 35 extends through the slots 14.
  • the terminal strip When fully inserted into the housing, the terminal strip is substantially completely enclosed and the terminal slots are aligned with the wire-receiving slots 17 and 18.
  • a cover 37 having locking legs 38 engaging detents 22, 23 may be used to cover a vacant cavity indicating the longitudinal extent of the terminal strip. Insulated wires may simultaneously be inserted into the terminals through the wire-receiving face so that the walls of the terminal slots penetrate the insulation to establish connection with the wire cores, commoning the wires. During wire insertion, the bight of the wire-connecting portions are supported by the shoulders 25 as described in U.S. Patent Application No. 859,067 (9072).
  • a suitable harness manufacturing method is described in U.S. Patent No. 3,859,724 and illustrated schematically in Figure 4.
  • Jigs 41 similar to those described in U.S. Patent Application No. 883,559 (9091), are mounted at predetermined locations on a board 42.
  • Each jig includes an inverted channel-section base 43 from opposite sides of which upstand wire- locating combs 44, 45 defining between them a connector receiving recess. Wires are laced into the combs in which the connectors (not shown) are mounted and inserted into the connectors by a pneumatically powered tool 46.
  • the tool has a head 47 housing an insertion ram (not shown) which head can be releasably attached to the jig by pivotal hooks 48 which engage in the opposite ends of the channel 43. Insertion forces are carried by the reinforcing ribs 19.
  • the connector may be mounted on a chassis by feet 26 to a common wires terminated in connectors of the kind described in U.S. Patent Application No. 859,067. Wires can be terminated at their ends or at an intermediate location.
  • the connector is a simple two part construction:
