Claims (1)

[Scope of utility model registration request] A plug having a grounding contact pin, a power supply contact pin, and a signal contact pin; a grounding contact member with which the grounding contact pin contacts; a power supply contact member with which the power supply contact pin contacts; In a connector comprising a signal contact member that contacts a contact pin and a socket to which the plug is connected, the plurality of contact pins or the plurality of contact members are connected to each other when the plug is connected.
The signal contact pin and the signal contact member may be brought into contact with each other after the ground contact pin contacts the ground contact member and the power contact pin contacts the power contact member. A connector in which the plugs or the sockets are arranged at different positions in the axial direction.
