  • Patent number: 4035047
    Abstract: Contacts and receiving sleeves within a connector insulator are sized to permit the contacts to be inserted into the sleeves of the insulator and lightly held in position. Each contact includes a press fit shoulder portion which protrudes from the bottom of the insulator and is adapted for press fitting into a receiving aperture formed in a mounting substrate. After the contacts are press fitted into the mounting substrate, a flat blade-like contact portion protrudes from the top of the insulator for electrical engagement with a female contact (not disclosed) while a contact tail portion extends below the substrate for wire wrap termination. The assembled connector configuration permits removal of the insulator by lifting it from around the contacts which it lightly engages. Further, with the insulator in place, any individual contact may be removed from both the insulator and the substrate for replacement in the event of damage.

  • Patent number: 3975072
    Abstract: A low profile connector for electrical components having a plurality of leads extending therefrom, such as integrated circuit packages. Rectangular folded contacts, each having an open top lead receiving socket portion, are press fitted into aligned apertures in a substrate with the socket portions lying above the substrate surface. An insulative housing having recesses therein open at each end is laid over the ends of the contacts to receive each one of the socket portions up into a recess in the housing. A component is receiving onto the top surface of the housing with the leads therefrom extending down through the top openings of the recesses into the lead receiving socket portions of the contacts.

  • Patent number: 3975078
    Abstract: A contact for electrical component leads is formed by first stamping an outline design from a sheet of relatively thin metal stock. The stamped piece is then bent and folded in four substantially right angle bends about the longitudinal axis of the contact. The folded contact is generally rectangular in cross-section with planar side walls including a four-sided open top lead-receiving socket portion, a four-sided press-fitting central portion and a three-sided tail portion generally square in cross-section. Each planar side of the lead-receiving socket portion also includes a tine extending angularly inwardly and downwardly to mechanically and electrically engage an axially aligned component lead when inserted down into the open top lead-receiving socket portion of the contact.
