An insertion reference surface (13c) having a predetermined outer-diameter size D1 is provided to extend by a predetermined length in an axial direction on an outer peripheral surface of an inner-side contact (13) among both cylindrical-shaped contacts overlapped with each other in inside/outside in the radial direction. A mutual mating relation is set so that the inner peripheral surface of the outer-side contact (23a) has an inner-diameter size D2 approximately same as an outer-diameter size D1 of the insertion reference surface of the inner-side contact (13). The outer-side (23a) contact can be smoothly inserted while carrying out positioning by the insertion reference surface (13c) of the inner-side contact (13). The inserting operation thereof is stably and precisely carried out, and the force of insertion is suppressed to be small, the positional stability upon mutual mating of both of the connectors is improved, so-called inclined mating is prevented, a good mating state is obtained, and an electrical contact state is improved. |
