  • Patent number: 4894022
    Abstract: A solderless surface mount card edge connector is presented. In one embodiment, a connector is attached to a printed circuit board 53. The connector includes a plurality of contacts and extrusions. A daughter board includes a rigid portion on which are attached a series of fingers. When the rigid portion of the daughter board is placed within the connector, the plurality of contacts are pressed downward and establish electrical contact with electrical regions on the mother board. Also, the downward force is transferred by the contacts into horizontal pressure so that electrical contact is established between the plurality of contacts and the series of fingers. In order to maintain the pressure two metal threaded spacers are pinned to the daughter board and fastened to the mother board via screws. Once tightened the assembly is protected from dislodging, even under vibration. The downward pressure, and thus electrical contact, is maintained.

    Abstract: An electrical connector for providing electrical connection to a substrate having contact elements thereon (e.g., a printed circuit board) wherein torsional contacts are utilized. The contacts, actuated by a vertically moving, slidable member (e.g., a cam plate) and horizontally moving actuator (e.g., a linear cam), resume a normal, twisted configuration to effect such connection with the respective contact elements. Each contact, preferably metallic (e.g., beryllium copper), includes a curvilinear edge segment while each contact element (e.g., plated copper wire) in turn includes a curvilinear contacting surface, these two members thus providing a single point form of contact while assuring effective wiping motion to remove undesirable contaminants, debris, etc. which may be located thereon. Relatively high contact forces (e.g., 200,000 PSI) are possible using the invention.

  • Patent number: 4752244
    Abstract: An electrical interconnect pin, particularly suitable for attachment to the edge of a flexible printed circuit board or "flex circuit", has an edge clip with an opening that can be temporarily enlarged to facilitate the attachment of the pin to the edge of a circuit board. The pin includes an elongated shank with a rectangular cross section and two substantially identical clips attached to opposite sides of the shank. To attach the pin to a printed circuit board, the pin is placed on a flat surface with the shank parallel to the surface. A force is then applied to the shank just below the clips and perpendicular to the surface. This force opens up the edge clip and the edge of the printed circuit board is then inserted into the opening of the edge clip. After the force is removed, the edge clip clamps down on the circuit board, temporarily attaching the pin to the board. The pins can then be permanently affixed to the board by soldering.

    Abstract: A zero insertion force connector is provided for flat cables having conductors on one or both sides. The ZIF connector includes a base having a plurality of generally parallel slots for receiving generally C-shaped portions of contacts with contact arms of unequal lengths. An actuator is slidably urged into contact with an initial fulcrum on the base. The actuator defines a cable channel into which the flat cable can be inserted such that the cable is guided between the arms of the C-shaped contacts. The actuator then is rotated about its initial fulcrum of the base, and the cable is urged into contact with anti-overstress fulcrums on the base. Continued rotation of the actuator urges the cable into the opposed arms of the contacts to make electrical connection. Resilient deflectable locking latches engage the actuator and hold the actuator into a fully seated condition.
