When assembling the charging pile, the mounting slots 124 located at the bottom are used to connect the corresponding cables, and the mounting slots 124 located on the left or right side are used to install other components.

[0036] Furthermore, the opening edge of the box 12 is continuously bent inward to form a constricted structure 121, and the edge of the constricted structure 121 is inclined outward to form a skirt 122, on which a sealing ring 14 is fitted.

[0037] In this embodiment, the cover 11 is bent inward around its perimeter to form a baffle 111. The baffle 111 has several riveting holes 112, and a retaining ring 113 is riveted to the baffle 111. For ease of manufacturing, the retaining ring 113 is composed of two C-shaped parts, which are riveted to the baffle 111 during riveting. The width of the retaining ring 113 is greater than the width of the baffle 111. One edge of the retaining ring 113 fits against the edge of the baffle 111, while the other edge extends beyond the bend of the baffle 111. When assembling the charging pile, the panel is installed at the front of the cover 11. The width of the retaining ring 113 extending beyond the baffle 111 is equal to the thickness of the panel, ensuring that the retaining ring 113 perfectly covers the panel, further enhancing the overall sealing of the charging pile.

[0038] Secondly, two first page plates 116 are provided on one side of the cover 11, and the two first page plates 116 are arranged vertically.
