Publication number: 20050077737Abstract: The present invention relates to a connector attached to a fulcrum end of a pivotal door handle and into which wiring extending from a sensor is introduced, the sensor being built into the door handle to detect a predetermined signal from surroundings, the connector having a contact connected to the wiring. The present invention reliably prevents water from infiltrating into the connector and eliminates the necessity to also replace the door handle when the connector is replaced. The connector includes paired latch arms provided on respective sides of the door handle and which can be installed in and removed from the door handle; and a seal member provided at a port through which wiring is introduced.Type: ApplicationFiled: September 10, 2004Publication date: April 14, 2005Inventors: Ryuichi Komiyama, Yoshinori Hitomi, Katsutoshi Fukunaga, Makoto Suzumura, Yukinobu Kunimatsu

Publication number: 20050050842Abstract: 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.Type: ApplicationFiled: September 10, 2004Publication date: March 10, 2005Inventors: Ryuichi Komiyama, Yoshinori Hitomi, Katsutoshi Fukunaga, Makoto Suzumura, Yukinobu Kunimatsu
