Wherein, the embedded portion 32 can be clamped with the clamping portion 12, as shown in fig. 2, at this time, the sealing body 31 is fixed on the first splicing element 10 through the embedded portion 32 and the clamping portion 12 and is disposed around the opening 11, and then when the second splicing element 20 is covered on the opening 11, the second splicing element 20 abuts against the sealing body 31 and compresses the sealing body 31, so that the sealing body 31 is compressed between the second splicing element 20 and the first splicing element 10, and a gap between the second splicing element 20 and the first splicing element 10 is sealed through the sealing body 31.

It should be noted that, in other embodiments, the clamping portion 12 may also be disposed on the second splicing element 20, so as to fix the sealing element 30 on the second splicing element 20, thereby facilitating the assembly of the sealing element 30. In still other embodiments, the first splicing element 10 and the second splicing element 20 may be respectively provided with the clamping portions 12, and the embedded portion 32 of the sealing element 30 may be clamped with the clamping portion 12 of one of the first splicing element 10 and the second splicing element 20 after being clamped with the clamping portion 12 of the other, so that the fixing and mounting of the sealing element 30 may be completed.

In this way, the sealing body 31 is matched with the clamping portion 12 through the embedded portion 32, so that the sealing body 31 can be fixed at a position around the opening 11, and when the second splicing element 20 is covered on the opening 11, the sealing body 31 can form a seal around the opening 11. Compared with the traditional installation mode of the sealing groove 21, the electrical box directly fixes the sealing piece 30 through the clamping part 12 and the embedded part 32, so that the step of placing the sealing ring in the sealing groove 21 is saved, and the assembly efficiency of the electrical box is greatly improved.

In some embodiments of the present application, the clamping portion 12 and the embedding portion 32 each include a plurality of clamping portions 12 and a plurality of embedding portions 32, which are disposed circumferentially around the opening 11, and each embedding portion 32 is clamped with at least one clamping portion 12, so that the sealing body 31 is fixed around the opening 11 by the plurality of clamping portions 12 and the plurality of embedding portions 32, thereby ensuring the sealing effect of the sealing member 30 on the opening.

In some embodiments of the present application, the clamping portion 12 includes a clamping hole 13 formed on the case, and the embedding portion 32 is convexly disposed on a side of the sealing body 31 facing the first splicing element 10, so that the embedding portion 32 can be embedded into the clamping hole 13, so that the sealing element 30 is fixed on the first splicing element 10 by respectively embedding the plurality of embedding portions 32 into the plurality of clamping holes 13.

In other embodiments, the insertion portion 32 may be a clamping hole 13 formed in the sealing body 31, the clamping portion 12 is convexly disposed on a surface of the box body abutting against the sealing member 30, and the sealing member 30 may be fixed on the first splicing member 10 after the plurality of clamping portions 12 are inserted into the plurality of clamping holes 13.
