  • Publication number: 20160118742
    Abstract: A connector includes a pair of connector housings, a fitting part provided in one connector housing of the pair of connector housings, and a fitted part provided in another connector housing and to which the fitting part is fitted. The fitted part has a frame and a movable housing. The movable housing is arranged within the frame, and is movable in a fitting direction. Timing to complete fitting between the movable housing and the fitting part is different from timing to complete fitting between the frame and the fitting part. The frame and the movable housing have a locking part which temporarily locks the movable housing within the frame. The locking part is restored by releasing the temporary locking in a state in which the fitting between the fitting part and the movable housing is completed. A periphery of the restored locking part is covered with a protection part.

  • Publication number: 20160028179
    Abstract: A connector device includes a wire harness side connector including a first housing, and a sensor side connector including a second housing. The first connector includes a third housing provided so as to be freely rotatable in the first housing. The first housing rotates with respect to the third housing and is fitted to the second housing. The first housing is freely movable with respect to the third housing in the axial direction between a pre-fitting position and a fitting completion position and has a force applied thereto by a spring on the pre-fitting position side. A rotational position return mechanism is provided that returns, when the connector fitting is released, the rotational position of the first housing to an initial rotational position during a process in which the first housing is moved from the fitting completion position to the pre-fitting position by an elastic force of the spring.

    Abstract: A first housing of a first connector being fitted to a second housing of a second connector includes first and second rotation check lock portions. A third housing of the first connector includes rotation rail portions with first and second rotation prevention walls. The first rotation prevention wall allows rotation of the first rotation check lock portion beyond the first rotation prevention wall in one rotational direction, and does not allow the rotation beyond the first rotation prevention wall in the other rotational direction to blocks the rotation at a rotational position of 180 degrees or more. The second rotation prevention wall does not allow rotation of the second rotation check lock portion beyond the second rotation prevention wall in the one rotational direction to block the rotation at a rotational position of 180 degrees, and allows the rotation beyond the second rotation prevention wall in the other rotational direction.
