  • Patent number: 11677184
    Abstract: A connector configured to be fitted with a mating connector includes a main housing, a sub-housing supported on the main housing to be slidable in a fitting direction with respect to the main housing in which the connector is fitted with the mating connector, and an operating member pivotably and slidably supported on the main housing. The main housing moves closer to the mating connector when the operating member is pivoted from a first posture to a second posture. The sub-housing moves in the fitting direction when the operating member slides from the second posture in a direction different from the fitting direction. The sub-housing has an erroneous fitting prevention part abutting against the mating connector in a state of incomplete fitting of the connector with the mating connector.

  • Patent number: 11245226
    Abstract: An electrical connector comprises a first housing, a second housing, a lever adapted to couple the first housing and the second housing with each other, a first interlock member, a second interlock member, a first cam mechanism adapted to mate the first housing and the second housing with each other with movement of the lever in a first direction, and a second cam mechanism. The second interlock member is configured to be mated with the first interlock member to energize an electric circuit. The first cam mechanism limits a moving direction of the lever to a second direction after moving in the first direction. The second cam mechanism is adapted to convert the movement of the lever in the second direction into movement in a mating direction of the first housing and the second housing to mate the first interlock member with the second interlock member.

  • Patent number: 10854860
    Abstract: An inter-battery connection device for connecting electrode terminals of a plurality of batteries comprises a housing, a bus bar attached to the housing, and a movable member attached to the housing. The bus bar electrically connects two electrode terminals of a pair of batteries adjacent to each other. The bus bar includes a pair of clips each contacting one electrode terminal and a coupling portion connecting the pair of clips. The movable member is movable between a temporary catching position attached to the housing and a final catching position attached to the housing. The movable member has a clip contact avoiding portion preventing contact between one of the clips and the electrode terminal in the temporary catching position and permitting contact between the clip and the electrode terminal during movement from the temporary catching position to the final catching position.

  • Patent number: 10707615
    Abstract: An electrical connector comprises a first housing, a mating terminal retained in the first housing, a second housing mated with the first housing, a contact member disposed in the second housing, and an insertion/extraction assist protrusion. The contact member is electrically connected with the mating terminal by pinching the mating terminal with a plurality of spring pieces facing each other. The spring pieces each have a contact portion protruding inward. The insertion/extraction assist protrusion is adapted to expand a gap between the spring pieces when the first housing and the second housing move relative to one another in a mating direction. The insertion/extraction assist protrusion is arranged offset from the contact portions in a plane crossing the mating direction and is arranged nearer to a start point of the mating than the contact portions during the mating in the mating direction.

  • Patent number: 10651595
    Abstract: A plug connector is detachably matable with a cap connector. The plug connector includes a lever performing mating with and unmating from the cap connector. The lever includes a cam groove for receiving a first boss of the cap connector, a boss rotation hole for receiving a second boss of an outer housing of the plug connector, and a catching protrusion sliding hole for receiving a catching protrusion of an inner housing of the plug connector. A first turning operation of the lever during unmating from a fully mated state extracts an interlock busbar of the plug connector from the cap connector to remove a short circuit of first conducting wires of the cap connector. A second turning operation of the lever during unmating moves a releasing protrusion into a clip spring of the plug connector to open the clip spring.

  • Patent number: 10297945
    Abstract: A connector comprises an interlock busbar adapted to be inserted into an interlock connector and short-circuit a pair of first conducting wires of a mating connector, a clip busbar adapted to pinch and short-circuit a pair of terminals of the mating connector, a housing, a lever, and a slider supported on the housing and slidable between an unmating position and a mating position. The lever removes the short circuit of the pair of first conducting wires by pulling out the interlock busbar from the interlock connector according to a first-half turning operation. The slider at the mating position blocks a second-half turning operation by interfering with the lever at an end of the first-half turning operation of the lever, and allows the second-half turning operation of the lever after a sliding operation of the slider to the unmating position.
