Definitions

  • This invention relates to an insulation displacement contact (“IDC”) terminal having a pressure- contact section where an individual cable is electrically connected through an insulation displacement.
  • IDC insulation displacement contact
  • this type of IDC terminal includes a pair of arms and a support section formed integral with the arms to support them.
  • the pair of arms form a slot to permit a cable to be inserted and electrically connected with the pair of arms. That is, a cable is forced into the slot between the arms, resulting in removing the insulation, and forming an electrical connection.
  • IDC terminal 10 has pressure-connection section 20 at its upper portion and additional connection section 30 at its lower portion. These sections 20 and 30 are obtained as a one-piece flat-like conductive plate pattern by punching a metallic plate with a die.
  • Pressure-connection section 20 comprises a pair of arms 21, and a support 22 for supporting the arms 21, whereby slot (hereinafter referred to as an IDC slot) 24 is formed.
  • Arms 21 define a pair of side surfaces of the slot 24 and support 22 constitutes the base.
  • the each forward end portions of arms 21 constitute a pair of ramps 25 each inclining toward IDC slot 24.
  • a pair of ridges 26 each projecting toward slot 24 are formed on the each inner side wall of the arms 21.
  • a thickness d A of ridge 26 is set smaller than a thickness d got the intact arms 21 as shown in Fig. 1 B.
  • Such a ridge is obtained by, for example, initially swaging a corresponding area of a conductive metallic plate to a desired thickness.
  • the bottom portion of said slot 24 is substantially circular in cross-section and the distance between the tops of said pair of ridges 26 is smaller than the diameter of said circular cross-section.
  • the IDC terminal so constructed is settled on housing 51 of electric connector 50.
  • the connection of individual cable 60 to pressure-connecting section 20 is achieved by pushing cable 60 into the IDC slot. That is, individual cable 60, when forced into IDC slot through opening 23, is first guided along ramps 25 and then forced into IDC slot 24 while deflecting arms 21 outward in a lateral direction. At this time, insulation 61 of cable 60 is partially removed by ramps 25 and ridges 26 to expose the wire group 62. As a result, cable 60 is firmly sandwiched between the opposing inner faces of the ridges of arms 21 to permit the exposed wire group 62 to be electrically connected to pressure-connection section 20.
  • each thickness of the ridges 26 in contact with the wire group in cable 60 is smaller than thickness d ⁇ of the rest of the arm.
  • the contact area for the arm and the wire group in cable 60 in the present invention is decreased to an extent of d A /d B in comparison with that of the conventional counterpart, indicating that all the stress on arms 21 is decreased to the extent of d A /d B in comparison with that of the conventional counterpart. That is, according to this invention it is possible to increase the structural strength of arms 21. If the structure of this invention requires the same strength as that of the conventional structure, the width of the arms can be reduced compared with that of the conventional counterpart, thus enabling a more compact IDC terminal.
  • the ridge may be integrally formed also on ramps 25 in which case the stress on the ramps 25 can be diminished when the cable is inserted into the IDC slot.
  • the ridges can be replaced by tapered figure. That is, the side edges of the opposing faces of arms 21 may-be-tapered along IDC- slot-24, as shown in Fig. 3.
  • Another connection section 30 may be not only of a male contact type but also of a female contact type.
  • a contact area between the individual cable and the pair of arms is decreased, thus reducing stress on the arms of the terminal.
