Definitions

  • An actuating plate is adapted to be inserted in the bore and cause the spring member piercing surfaces to pierce the insulation of the flat cable and thus make contact with conductors in the flat cable.
  • the actuating plate may be formed of rib members with each rib member being associated with one of the spring members.
  • the spring members may be mounted in the bore in an unstressed condition prior to insertion of theactuating plate.
  • the spring members may be in the form of semieliptical beam, with the end thereof having a pair of piercing surfaces formed thereon.
  • flat conductor cable connectors in the present invention provide a simple arrangement wherein the flat conductor cable need not be stripped to expose the conductors prior to termination.
  • Piercing spring members are provided which need not be loaded until the actual connection between the cable and the conductor occurs.
  • the entire conductor assembly can be made from simplified parts and readily assembled.
  • FIG. 2 illustrates the flat cable connector in FIG. 1, in cross section
  • FIG. 3 shows a perspective view of the spring contact member used in the connector of FIG. 1;
  • FIG. 4 illustrates the flat cable connector of FIG. 1 prior to insertion of the conductor
  • FIG. 5 depicts the flat cable conductor of FIG. 4 with the actuation plate partially inserted
  • FIG. 6 shows the flat cable connector of FIG. 4 with the actuation plate fully inserted
  • FIG. '7 illustrates a cross-sectional view of the conductor of FIG. 1 taken along the lines 77.
  • FIG. 1 a preferred embodiment of the invention which contains a connector assembly 12, formed of a plurality of receptacle connectors 16. It should be understood to one skilled in the art that each of the receptacle connectors 16 have a plug connector associated therewith.
  • the receptacle connector 16 comprises a plurality of contacts 22 whose front end is tapered as at 24 and which are adapted to be mated with contacts in a plug connector.
  • the contacts are shown in greater detail in cross-sectional view mounted in the conductor in FIG. 2. Further, FIG. 3 illustrates the contacts 22 in perspective view.
  • the contact 22 further comprises'an enlarged central portion 26 having a tine 28 formed therein.
  • the rear end of the contact is formed of a semieliptical beam 32 having a slight bell 34 in the forward end which 'is formed integral with the portion 26 and rearpiercing surfaces 36 formed between a central end member 38.
  • the use of a pair of piercing surfaces provides both contact redundancy and structural integrity.
  • the contacts 22 are normally made of a high-copper bearing spring material such as phosphor bronze.
  • the receptacle housing is formed of an enlarged forward bore portion 42 which terminates in a forward facing shoulder 44.
  • a reduced-diameter central bore portion 46 is interconnected to the forward bore portion 42 and terminates in a forward facing shoulder 48.
  • a still further reduced rear bore section 52 interconnects the bore portion 46 with an enlarged rear bore portion 54.
  • the junction of the rear bore portion 54 and the bore portion 52 containing an upper rearward facing shoulder 56 and a lower rearward facing shoulder 58.
  • the rear bore portion 54 also contains a top wall surface 59 and a bottom wall surface 60.
  • the forward bore portion 42 contains a plurality of axially extending grooves 6264 along its top wall and bottom walls, respectively.
  • the rear outer surface of the receptacle housing contains lip members 72 which extend in opposite directions and are used to mate with a shell boot 74 after interconnection of the contacts with the fiat cable.
  • the forward face of the receptacle housing has at either end, formed slightly to the rear of the front surface, a pair of flange portions 82.
  • Each of the flange portions 82 contains in its forward facing surface a hexagonally shaped recess 84.
  • Mounted by means of a screw 86 in the recesses 84 are polarizing posts 88.
  • the posts 88 may be rotated in any one of three positions due to the hexagon shape of the recess 84 to thus vary the polarizing positions.
  • each of the connector housings Mounted on the top surface 90 of each of the connector housings are raised members 92 which mate with grooves 94 on the bottom surface of each of the receptacle connectors, allowing the receptacle connectors to be stacked and positioned. Further, rearwardly facing openings 96 in the housing allow screws 98 to be inserted therein and allow a washer 100 and a nut (not shown) to fasten the receptacle connectors together.
  • Plug connectors for mating with the receptacle connectors 16 can have mounted therein a plurality of conventional fork-type contacts 122.
  • the contacts 122 may contain releaseftines 124 for removing the contacts from the plug connector housing. Further, the rear end of the contact may contain crimping means 126 for connection of a wire 128 to the contact 122.
  • plug connector may utilize contacts 122 for interconnection with conventional wires, other arrangements are possible.
  • the plug connector could as well be used to interconnect to flat cable similar to the manner depicted for the receptacle connector 12.
  • the plug connector forms no part of the invention.
  • FIG. 7 there is shown a cross section of the flat cable utilized with the invention of FIG. 1.
  • the cable comprises conductors 152 which are mounted within the insulating material 154. In order to make contact with the conductors 152 it is necessary to pierce the insulation material 154 or otherwise remove it.
  • FIG. 4 there is shown a view of the receptacle connector broken away prior to insertion of the cable 150 therein.
  • An actuating plate 162 contains a fiat top surface 164 and a bottom surface 166 having axially extending rib members 168 extending downwardly therefrom.
  • the cable is inserted from the rear of the receptacle connector into the bore 54 until it reaches the lower rear facing shoulder 58 and thus the cable 150 is between the piercing surfaces 36 and the bottom surface 60 of the bore.
  • the plate 162 is inserted from the rear of the receptacle connector, as shown in FIG. 5 with each of the rib members 168 forming an insulating barrier between adjacent contacts.
  • each of said spring members being mounted in a bore formed in said connector member and terminating in a piercing surface which faces substantially toward one of the surfaces of said bore with a first clearance space being formed between said piercing surface and said one bore surface for insertion of a flat cable in said first clearance space, and
