Patent ID: 8628362

Claim:
A connector to be connected to a mating connector, comprising: a connector main body including a cylindrical member, a supporting member disposed in the cylindrical member, a terminal supported on the supporting member, and a fitting portion arranged to be deformable in a radial direction thereof, said fitting portion having an engaging portion for engaging with the mating connector when the mating connector is completely inserted into the fitting portion; a movable sleeve disposed around the connector main body to be movable along an axial direction thereof relative to the connector main body, said movable sleeve including a diameter control portion for controlling the fitting portion so that the fitting portion is not capable of expanding when the movable sleeve is situated at an initial position and the fitting portion is capable of expanding when the movable sleeve moves toward a distal end or a proximal end of the connector main body from the initial position; an elastic deformation member disposed to be elastically deformable in a radial direction thereof; an accommodating portion disposed between the connector main body and the movable sleeve for accommodating the elastic deformation member; and a transmission unit for transmitting a force in the axial direction from the movable sleeve to the elastic deformation member when the movable sleeve moves, and for transmitting a force in the radial direction from the elastic deformation member to the movable sleeve when the elastic deformation member returns to an original shape.
