The front end of the mounting hole 111 is provided with a step 112, and the step 112 is in stop fit with the flange 61 on the bushing 6 in the forward direction to prevent the bushing 6 from being released from the mounting hole 111 forward. The elastic piece 5 is arranged between the bushing and the metal end cover, and the elastic piece selects the spring 5. Under the condition that the plug and the socket are not inserted, under the action of the spring 5, the bushing 6 abuts against the step 112, the metal end cover 4 abuts against the front end face of the pressure sensor 3, at the moment, the metal end cover 4 slightly presses the sensitive area (detection face) of the pressure sensor under the action of the spring, and the slight pressure enables the system not to judge that the headstock is in the inserted state. The pressing plate 2 not only plays an axial limiting role for the metal end cover 4 so as to prevent the metal end cover from being separated from the rear end of the pin hole, but also provides a stress supporting plane for the pressure sensor 3. The pressure sensor 3 is led out of the plug housing 1 through a signal line and is electrically connected with an external control module and the like, so that the output of a pressure signal is realized.
