[0070] In some embodiments, the first seal 313 is disposed inside the first carrier 1, with one end of the first seal 313 passing through the first opening. In this case, the first mounting pieces 315 are disposed on both sides of the first seal 313 and located outside the first carrier 1, and the first mounting pieces 315 are fixedly connected to the first carrier 1. Similarly, the second seal 413 is disposed inside the second carrier 2, with one end of the second seal 413 passing through the second opening.

[0075] Specifically, in some embodiments, when the first magnetic member 32 and the second magnetic member 42 are not conductive, the first error-proofing groove 34 can be provided on the first magnetic member 32 , and similarly, the second error-proofing block 44 is correspondingly provided on the second magnetic member 42 .

[0076] In some embodiments, a first space 36 is provided inside the first sealing member 313 and between the first connecting contact 331, the first magnetic member 32 and the first opening. A baffle 35 is provided at the first opening, and one end of the baffle 35 is movably connected to the first sealing member 313. When the first electrical connecting buckle 3 is connected to the second electrical connecting buckle 4, the portion of the second sealing member 413 extending out of the second opening is inserted into the first space 36.

[0077] Specifically, such as Figure 5 As shown, the connection between the first electrical connection buckle 3 and the second electrical connection buckle 4 is hidden. At this time, a first space 36 is further provided inside the first sealing member 313 and between the first connection contact 331, the first magnetic member 32 and the first opening.
