  • the male terminal cover 50 is locked to the interference part 54 of the semi-lock part 53 at the exposed position, and the male terminal cover 50 is moved to the protected position. Since the restricting portion 41 that restricts the relative displacement is provided, the male terminal support body 30 and the male terminal cover body 50 are prevented from accidentally sliding relative to each other when the male terminal cover body 50 is in the exposed position. be able to.
  • the restricting portion 41 is disposed away from the interference portion 54 when the male terminal covering 50 is in the protected position, when the male terminal covering 50 is slid relative to the male terminal covering 50, It is possible to avoid excessive frictional resistance generated between the terminal covering body 50 and the smoothness of the relative slide can be ensured.
  • the male terminal support body is disposed on the upper side and the male terminal covering body is disposed on the lower side with respect to the male housing.
  • the male terminal support body is disposed on the male housing. May be arranged on the lower side and the male terminal cover on the upper side. Further, the male terminal support and the male terminal covering may be arranged on both the left and right sides with respect to the male housing. The same applies to the female housing, the female terminal support and the female terminal covering.
