Definitions

  • the present invention relates to an electric connector terminal structure and a method of making the same from an elongated piece of thin metal sheet.
  • U-shaped connector terminal blanks are stamped and formed of an elongated strip of thin metal sheet, and such U-shaped terminals are used to receive mating pin terminals in their pin receptacle gaps.
  • the terminals are arranged in parallel and are integrally connected to a carrier strip. In the parallel-arrangement the terminals are oriented relative to an insulating connector housing with their U-shaped front ends directed to the terminal slots in the insulating connector housing. All the terminals are inserted into the terminal slots from the rear side of the insulating housing at the same time to complete an electric connector.
  • Fig.4 see Japanese Patent Application Laid-Open No.7-169523 and Utility Model Application Laid-Open No.4-23065).
  • a pair of contact arms 91a and 91b of the terminal 90 face each other, and are integrally connected to a shank via a joint piece 92.
  • the opposite contact arms 91a and 91b define a pin receptacle gap 93 therebetween, forming contact portions on the inner surfaces of the ends.
  • a series of terminal blanks 95 are stamped from an elongated thin metal sheet. These terminal blanks 95 are parallel at regular intervals P, and are integrally connected to a carrier strip 94. The joint piece 92 of each terminal blank 95 is bent to be perpendicular to the opposite contact arms 91a and 91b to provide a complete terminal 90.
  • a set of parallel terminals are inserted into the terminal slots of a connector housing at the same time.
  • Such simultaneous insertion of numerous terminals is prevented if the slot-to-slot interval in the connector housing is smaller than the blank-to-blank interval of the terminals, and therefore, in such a case, terminals have to be removed from the carrier strip and are inserted individually into the terminal slots one after another to complete an electric connector.
  • One object of the present invention is to provide electrical terminal structure which permits the blank-to-blank terminal interval to be reduced to a minimum.
  • Another object of the present invention is to provide a method of making such terminals efficiently.
  • an electric connector terminal of stamped-and- formed thin metal sheet includes a pair of parallel contact arms having contact portions which are formed at the ends of the opposite contact arms to define a pin receptacle gap therebetween, is improved according to the present invention in that the pair of parallel contact arms extend in the form of "U" with their shearing planes facing each other, each of said contact portions being formed by bending its inner edge substantially perpendicular to the plane of the metal sheet.
  • the blank-to-blank joint space as required in the conventional parallel-arrangement of terminal blanks can be reduced, so that the blank-to-blank space may be reduced to possible minimum.
  • the confronting contact portions are formed such that a mating male pin terminal is slidably accommodated in the pin receptacle gap establishing good electrical contact therebetween.
  • a method of stamping and forming a thin metal sheet into electric connector terminals, each comprising a pair of parallel-arranged contact arms having contact portions formed at their ends to define a male pin terminal receptacle gap, is improved according to the present invention in that it comprises the steps of
  • an elongated piece of thin metal sheet is stamped to provide a plurality of terminal blanks 3 arranged in parallel and integrally connected to a carrier strip 2.
  • the terminal blanks 3 are formed into finished terminals 1.
  • the finished terminals 1 are integrally connected to each other via a sub-carrier strip 5, and to the carrier strip 2 via support pieces 4.
  • the finished terminals 1 can be separated from each other by cutting the opposite boundary lines 6 between the terminal 1 and the sub-carrier strip 5.
  • each terminal 1 includes an engagement section 7 for engaging walls of a selected terminal slot in a dielectric housing (not shown), an "L" shaped portion 8 integrally connected to the front side of the engagement section 7 and a tail section 10 integrally connected to the rear side of the engagement section 7.
  • the tail section 10 is a crank-like shank having a press-fit pin 11 formed at its end (see Fig.2).
  • each "L" shaped portion 8 includes a contact portion 9 having a pair of parallel contact arms 13 arranged in the form of "U” in the plane of the engagement section 7, each contact arm terminating in a contact portion 14.
  • the inner edge of the free end of each contact arm 13 is formed by bending it substantially perpendicular to the plane of the engagement section (in the direction from the front to rear side of the sheet of Fig.1).
  • the contact arms 13 are then sized to define a pin-receptacle gap 15 between the opposite contact portions 14 which face each other.
  • the "L" shaped portion is then bent at substantially a right-angle to position the plane of the contact arms 13 perpendicular to the plane of the engagement section 7.
  • terminals 1 are arranged in parallel with the shearing planes 13a of their contact arms 13 facing each other, permitting the paired contact arms 13 and the arm joints 12 to be arranged at smaller intervals, thus permitting terminals 1 to be arranged in parallel at significantly reduced intervals P (see Fig. 1).
  • the terminal-to-terminal interval in the parallel-arrangement of conventional terminals 90 shown in Fig.5 is 3 mm wide whereas the terminal-to-terminal interval in the parallel-arrangement of terminals 1 shown in Fig. 1 is 2 mm wide.
  • the reduced terminal-to-terminal interval enables a set of terminals 1 to be press-fit in the terminal slots of a connector housing at the same time while all terminals 1 remain integrally connected both to the carrier strip 2 and the sub-carrier strip 5.
  • Each engagement section 7 has projections 16 and 7 formed on its front and rear sides. The projections are engaged by the inner opposite side walls of each terminal slot (not shown) when the terminal 1 is press-fit therein. Specifically, the terminal 1 is inserted in the terminal slot until the front projections 16 have engaged the terminal slot, so that the terminal may be tentatively fixed. Then, the boundary lines 6 are cut to separate the terminal 1, and the terminal 1 is pushed in to the terminal slot until the rear projections 17 have engaged the terminal slot.
  • all terminals 1 are held with a terminal mounting tool, the terminals 1 are then separated by cutting the boundary lines 6 and the terminals are press-fit in the terminal slots of an insulating housing.
  • all terminals may be inserted in the terminal slots of a housing at the same time, and accordingly connectors can be manufactured efficiently.
  • the contact portions 14 of the opposite contact arms 13 face each other with their formed surfaces directed towards each other to form the male pin terminal receptacle gap. This arrangement prevents a mating pin terminal from being damaged should the shearing surfaces 13a of the contact portions be used to form the pin receptacle gap.
