  • Patent number: 11081839
    Abstract: A connector has a protection member movable to a partial locking position and a full locking position with a male tab positioned in a receptacle of a male housing. The female housing includes a hook, and the protection member includes a hooked portion capable of contacting the hook at the full locking position. The receptacle includes a contact portion capable of contacting the hooked portion when the protection member is at the partial locking position. The protection member is movable from the full locking position to the partial locking position with the hooked portion held in contact with the hook. The protection member is stoppable at the partial locking position in a state where the hooked portion is in contact with the contact portion to be deflected in a direction separating from the hook.

  • Patent number: 10910762
    Abstract: A first housing includes a wide connection surface and a bearing formed on an edge on one side along the longitudinal direction of the connection surface. A second housing includes a side surface formed to face in a direction intersecting a connecting direction of the first and second housings. A lid is displaceable about a shaft supported by the bearing portion to a closed position where the lid covers the connection surface and an open position where the lid member contacts the side surface. The lid is biased from the open position to the closed position by a biasing member. An outer shape of the lid has a long side arranged along the longitudinal direction of the connection surface and a short side intersecting the long side and shorter than the long side.
