  • Patent number: 7402043
    Abstract: The present invention relates to a connector holding structure in which a connector is held in a door frame, the connector being mated with a mating connector attached to a fulcrum end of a door handle and pivotally held in the door frame. The connector holding structure according to the present invention allows the connector to be smoothly mated with the mating connector while permitting a change in the orientation of the connector caused by a pivoting motion of the door handle. The connector has two projections arranged on each side in a horizontal direction. A door frame has a guide groove extending along a horizontal direction in association with a direction in which the two projections are arranged, and two grooves extending downward from the guide groove in association with the two projections to permit pivoting motion of the connector.
