  • Pin protector
    Patent number: 4197945
    Abstract: An apparatus to removably enclose and thereby protect electrical connector ins attached to circuit boards. The pin protector has parallel flanges and a hinge to provide for the opening of an enclosing section to allow it to be placed about the pins. The memory properties of the hinge force the enclosing section to remain securely positioned. The pin protector is formed from an extrusible material and thus can be manufactured in any length without requiring the mold to be changed.

  • Pin loading system
    Patent number: 4059890
    Abstract: A pin loading system to load wire wrap pins into a master interconnect bo. A loading fixture includes a rod positioned within a wedge formed by the inclined interiors of a pair of abutting clamps. Its height therein may be varied by adjustment of a pair of knobs, allowing the alternative loosening and securing of pins to be mounted to a board. A shim placed below the fixture during the wave soldering process assures resilient pin connection.

  • Connector assembly
    Patent number: 4054345
    Abstract: A connector assembly to complete electrical connection between packaged electrical components. A connector header and a lead-in header commute by means of internal channels to form paths for an array of contact pins. Each pin is dimpled for self-retention in a channel after insertion. The design of the connector header allows continual access to the pins for individual removal in case of failure. Header design is symmetrical, allowing fabrication of a variety of connector lengths from a single mold.

  • Test connector
    Patent number: 3997231
    Abstract: A compact test connector having a slim design to permit side to side installation on a master interconnect board, allowing simultaneous testing of multiple modules. A contact board contains redundant contact surfaces. A simple and compact camming device acts in conjunction with the contact board to impart zero device insertion force and simplified replacement of the most degradable components.

  • Machine for unloading micro-electronic beam lead chips
    Patent number: 3961409
    Abstract: This invention is directed to a machine for unloading micro-electronic beam lead devices from a carrier. The machine removes the resilient clip, base and circuit board from the cover and the chip so that the beam lead chip is exposed and can be picked up and bonded onto a hybrid circuit substrate.
