Definitions

  • the present invention relates to a high current electrical socket terminal for such uses as in automotive high current connectors.
  • a solid brass material is machined to include either a pin and socket at one end, and a wire connecting bore at the opposite end.
  • a wire to be terminated is first stripped and then inserted in the bore, whereupon the wire connecting portion is crushed to crimp the material forming the bore around the wire.
  • the wire size varies the crimp quality could be affected by the increase or decrease of the void within the wire crimp area by the wire.
  • the smaller the conductor the more thoroughly the wire crimp area must be crushed in order to terminate the wire.
  • EP-A-0 254 986 discloses an electrical pin terminal and an electrical socket terminal mateable to each other and each comprising a front contact portion and a rear wire crimp portion.
  • the front contact portion of the pin terminal is tube-shaped.
  • a tube-shaped inner spring contact including a plurality of spring contact arms inwardly directed and suspended between a forward band portion and a rearward band portion.
  • the tube-shaped pin portion and the tube-shaped inner spring contact are dimensioned relative to each other such that there is radial and axial play between them.
  • the socket terminal comprises a tube-shaped socket contact section, an inner contact sleeve having contact spring arms and a contact pin arranged centrally within the inner contact sleeve. There is axial play between the socket contact section and the inner contact sleeve of the socket terminal.
  • EP-A-0 283 768 discloses a composite female contact comprising an elastic contact element and a housing body housing the contact element.
  • the contact element as well as the housing body are mate of any metal.
  • EP-A-0 188 751 discloses a connector socket for electrically connecting dual-in-line packages of integrated circuits.
  • the connector circuit has an insulation block with a top face and a bottom face. Bores through the block have tapered inlet mouths at the top face.
  • Metal tubular socket terminals are press-fitted in the bore portions below the tapered mouths and have pins projecting from the bottom face of the block.
  • the socket terminals carry sleeve-shaped contact elements positioned inside each of the socket terminals for physical and electrical contact with the pins of the integrated circuit packages. The top edge of the contact element is flush with the socket top edge.
  • the diameters at the bottom parts of the tapered inlet mouths are smaller than the diameters of the bore sections so that there is formed an abutment shoulder for the top ends of the tubular socket terminals and the contact elements.
  • the axial length of the contact elements is smaller than that of the tubular section of the socket terminals.
  • the abutment shoulders prevent the contact elements from being withdrawn out of the socket terminals. There is, however, no measure preventing the contact elements from being pushed towards the bottom end of the tubular section of the socket terminals, be it at the time of assembling the contact elements into the tubular sockets or be it at the time of inserting over-sized pins of an integrated circuit package.
  • the outer contact body 10 is stamped from a flat sheet of material and rolled into a cylindrical configuration having an axially extending seam at 14. The cylinder is held in a closed position by way of interlocking tabs 16 and 18 which prevent the radial expansion of the cylindrical body.
  • the outer contact body 10 includes a constricted portion at 20 formed by a transition at 22.
  • the outer contact body 10 further includes three raised sections 24 (only two of which are shown in Figure 3) formed by a sheared portion at 25 which forms a stop edge at 26, as shown in Figure 4.
  • the raised sections 24 are formed to be radially equidistant with the outer diameter of the front section 11, as best shown in Figure 4.
  • the terminal further comprises a sheared band portion 28 which is formed to be radially equidistant with the front section 11, as best shown in Figure 4, and includes a sheared edge 30 in opposing relation to the edge 26.
