  • Patent number: 6817892
    Abstract: As a structure for electrically connecting conductors of a flat cable (flat wire member) with a circuit board, an end of the flat cable is split into split pieces, and connectors (second connectors) are mounted at the ends of the respective split pieces. A connector (first connector) provided with two connecting portions for the connectors are mounted on the circuit board. When the respective connectors mounted on the flat cable are connected with the connector, the respective conductors of the split pieces are brought into contact with terminals accommodated in the connector. The flat cable or the flat wire member can be easily and securely connected.

  • Patent number: 6755680
    Abstract: A fixture device for use in connection of a flat wire member of a terminal connector is so constructed as to bring conductors of a flat wire member into contact with terminals by mounting a connector at an end portion of the flat cable and connecting the fixture device with a connector mounted on a circuit board to insert the end portion of the flat cable into the connector. The connector is provided with a pair of pivotally changeable handles. The handles extend in a direction opposite from an engaging direction of the connector with the connector while standing upright with respect to the rear end surface of the connector. Then operability in connecting or detaching the flat wire member can be improved.

  • Patent number: 6733325
    Abstract: A connector assembly is provided with a connector (first connector) to be mounted on a circuit board and a connector (second connector) for holding a flat cable flat wire member). When the two connectors are connected with each other, an end portion of the cable is inserted into the connector to bring conductors of the cable into contact with mating terminals. The connector is provided with a plate-shaped holder, and the cable is supported on this holder in such a state as to be displaceable in widthwise direction. On the other hand, the connector is provided with a pair of locking pieces as a positioning portion. When the two connectors are connected with each other, the respective locking pieces directly come into contact with the cable being inserted into the connector from widthwise outer sides, thereby positioning the cable with respect to the connector in widthwise direction.
