  • Patent number: 4050769
    Abstract: Electrical contacts are stamped and formed into a right angle configuraton for simultaneous insertion and housing in an effectively removable connector insulator. Linear receiving sleeves may be formed in each of two sections of the insulator, which sleeves meet at right angles, one to the other, when the insulator is assembled. Each linear sleeve is constructed to permit one of the linear portions of the contact to be inserted therein. The assembled insulator serves as a holding fixture and seating tool for transmitting forces applied to the top of the insulator to each one of the contacts for inserting an extended portion thereof into a contact receiving aperture in a mounting substrate for rigid mounting therein, with the orthogonal portion of the contact lying generally parallel to the substrate. The contact of the assembled connector is then in a configuration for parallel to the mounting substrate rather than perpendicular thereto.

  • Patent number: 4045868
    Abstract: Press fit contacts having upper mating portions are stamped, formed and oriented out of sheet material for simultaneous insertion and housing in a removable connector insulator. Receiving sleeves formed in the insulator are constructed to permit the contacts to be bottom loaded into the sleeves, seated and lightly held therein. Each contact includes an intermediate press fit collar portion which engages a mating shoulder in the insulator. The insulator serves as a holding fixture and seating tool for transmitting insertion force applied to the top of the insulator to each one of the contacts for press fitting them into contact receiving apertures in a mounting substrate. The contacts held by each insulator are all simultaneously press fitted into the substrate by continuing to apply pressure to the top of the insulator until it is mounted flush upon the substrate.
