For example, the cover 116 may be detachably connected to the bottom case 118 by means of clamping, riveting or screwing, so that an operator can conveniently detect the grounding states of the equipment in the electrical bin 510 and the equipment in the battery bin 530 on the first insulator 102 and the second insulator 108 after opening the cover 116.
In one embodiment, the bottom of the bottom case 118 is provided with a first through hole and a second through hole; a first end of the first insulator 102 is connected to a first end of the first main ground line 210 through the first through hole; the first end of the second insulator 108 is connected to the first end of the second main ground line 310 through the second through hole.
The first end of the first insulator 102 is connected to the first end of the first main ground wire 210 through the first through hole, such that the first end of the first insulator 102 is exposed outside the bottom case 118, thereby facilitating the connection of the first main ground wire 210 to the first end of the first insulator 102. The first end of the second insulator 108 is connected to the first end of the second main ground wire 310 through the second through hole, such that the first end of the second insulator 108 is exposed outside the bottom case 118, thereby facilitating the connection of the second main ground wire 310 to the first end of the second insulator 108.
In one embodiment, as shown in fig. 4, the grounding box 10 further includes a sealing ring 122, where the sealing ring 122 is disposed between the cover 116 and the opening of the bottom box 118, so as to further improve the sealing effect between the cover 116 and the bottom box 118, and further enhance the waterproof and dustproof sealing effect. An exemplary seal 122 may be a silicone seal 122.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
