In this embodiment, since the resistance of the resistor block 242 is large, the current passing through the contact portion is small when the male side inner conductor 13 is in contact with only the resistor block 242, and thus the generation of an arc can be suppressed.
Specifically, the outer guide 21 is provided with a heat radiation hole 25. In this embodiment, heat generated by the operation of the terminal can be discharged through the heat dissipation holes 25, so as to prevent the service life from being affected by heat accumulation inside the outer guide sleeve 21.

When the inner guide sleeve 11 gradually moves to the innermost end of the outer guide sleeve 21, the inner guide sleeve 11 contacts with the friction wheel 246 and drives the friction wheel 246 to rotate, and then the wedge 244 is driven to move right by the connecting rod 245, so that the slide block 241 moves down along the inclined plane of the wedge 244, and the resistor block 242 is separated from contact with the male side inner conductor 13 and the female side inner conductor 23, so that the heating of the access circuit is avoided. When the inner guide sleeve 11 moves to the innermost end of the outer guide sleeve 21, the clamping block 222 is clamped into the clamping groove 225 under the elastic force of the elastic piece 221.
