  • Card biasing device for card edge connectors
    Patent number: 4477138
    Abstract: The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.

  • Electrical terminal with cavity compensator
    Patent number: 4429459
    Abstract: A compliant terminal pin for use in electrical connectors for housings or circuit boards and the like which is press fitted into position and is retained in the connector housing, printed circuit board or the like by means of a friction fit. The terminal includes a rigid post at one end and a resilient spring contact structure at the other end thereof. The contact structure and the post are joined by an intermediate section having an aperture therethrough and a lance or tyne extending outwardly from the bottom of the aperture, the tyne being fittable into the aperture but being of smaller dimension. The intermediate section is a spring member having tapered sides with the narrow portion of the taper extending toward the post. The intermediate section can move inwardly from both sides by spring type action to occupy a portion of the aperture, thereby decreasing the dimension across the intermediate section.
