A wedge-shaped plug rod 408 is slidably connected to the inner wall of the groove, and the inclined surface of the wedge-shaped plug rod 408 is extrusion-slidably connected to the inclined surface of the wedge-shaped block 411. The wedge-shaped block 411 is clamped with the inner wall of the card groove. A pull ring 414 is provided at one end of the guide rod 412, and one end of the guide rod 412 slides through the inner wall of the movable groove and is fixedly connected to the pull ring 414.

[0027] Specifically, when the bus duct 1 is spliced, the waterproof shell 1 401 and the waterproof shell 2 402 can seal the connection of the bus duct 1, thereby improving the waterproof effect of the connection of the bus duct 1. At the same time, since the waterproof shell 1 401 and the waterproof shell 2 402 are both made of graphene material, the excellent sealing performance of the graphene material is utilized to further improve the waterproof ability of the bus duct 1 and reduce the safety hazards caused by environmental humidity.
