For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0043] Please refer to Figure 1 , the charging pile 10 usually includes a charging module, and the charging gun is connected with the charging module through a cable. The charging module is usually arranged inside the pile body 11. The charging module can convert alternating current from the power grid 12 into direct current or alternating current required by the vehicle 13, and transmit the current to the charging gun 20 through the cable, and the charging gun 20 is connected with the vehicle 13, so as to realize the charging of the vehicle 13.

[0056] Please refer to Figure 5 , Figure 6 and Figure 7In the above embodiment, the connection portion 41 is connected with the power supply portion 42 through a threaded structure. It can be understood that the connection portion 41 is connected with the power supply portion 42, and the power supply portion 42 can transmit current to the connection portion 41, and then the connection portion 41 transmits the current to the vehicle 13. The threaded structure makes the connection between the connection portion 41 and the power supply portion 42 detachable, and the connection portion 41 can be detached when charging using the first charging standard.

[0057] In addition, the threaded structure can increase the contact area between the connection portion 41 and the power supply portion 42, facilitating the realization of current conduction.
