[0034] Since a sealing element 20 is provided around the outer periphery of the waterproof wiring area 101 of the charging pile in this embodiment, the sealing element 20 is pressed and tightened by the pressing member 30. At the same time, the pressing member 30 can be locked in the pressing position for pressing the sealing element 20 by the locking member 40. With such an arrangement, wires such as external power supply wires and signal wires of the charging pile can be connected from the waterproof connector 102 to the waterproof wiring area 101 to be connected to the wiring terminal 103 at the waterproof wiring area 101. Compared with the charging piles in the prior art, a sealing element 20 and a pressing member 30 are provided around the outer periphery of the waterproof wiring area 101 in this embodiment, and the pressing member 30 is always locked in the pressing position for pressing the sealing element 20 by the locking member 40, that is, the sealing element 20 is always in a squeezed state, and the sealing effect is better, which can significantly improve the waterproof and dustproof performance of the charging pile in this embodiment, and the safety level can reach above IP6 level, which can well meet the outdoor use requirements of the charging pile.

[0035] Specifically, the main body 10 in this embodiment includes a base 11 and a cover 12. The base 11 and the cover 12 enclose to form the above-mentioned waterproof wiring area 101. The terminal 103 and the waterproof connector 102 are arranged on at least one of the base 11 and the cover 12. That is to say, the terminal 103 can be arranged on the base 11 or on the cover 12, and the waterproof connector 102 can be arranged on the base 11 or on the cover 12. The attached Figure 4 shows a situation where both the terminal 103 and the waterproof connector 102 are arranged on the cover 12. Compared with the situation where the terminal 103 and the waterproof connector 102 are respectively arranged on the base 11 and the cover 12, the way of arranging both the terminal 103 and the waterproof connector 102 on the cover 12 in this embodiment is more convenient for connecting the wire harness, and when the cover 12 is opened for maintaining the charging pile, it is not easy to cause the wire harness to be pulled.

[0036] Certainly, in other embodiments of the present application, the main body 10 can also be assembled by more than three structural bodies, rather than being limited to the base 11 and the cover 12 described in the present application. In addition, the main body 10 in this embodiment is generally a columnar structure, and this columnar structure can be a cylindrical structure or an elliptical cylindrical structure, which is not specifically limited in the present application.

[0037] Furthermore, a cavity 1101 is arranged on the base 11 in this embodiment, and an annular groove 111 is arranged on the base 11.
