The surface of the conductive shaft 22 is covered with a stretching spring 25, and the two ends of the stretching spring 25 are respectively fixedly connected to the surfaces of the connector 1 and the first conductive contact finger 11.
[0021] Furthermore, if Figure 4 As shown, an anti-loosening mechanism 3 is arranged at the bottom of the connector 1, and the anti-loosening mechanism 3 is composed of an anti-loosening component 31 and a pin groove 32. The pin grooves 32 are opened at equal intervals on one side of the conductive shaft 22, and an anti-loosening component 31 is arranged on one side of the pin groove 32. The anti-loosening component 31 is installed on the surface of the supporting slider 24.
