When the cover plates 1 are connected, the sealing protrusion 5 and the sealing groove 6 are clamped, and the sealing gasket 7 is cooperated to strengthen the sealing; the cross-sectional shape of the sealing protrusion 5 and the sealing groove 6 is set to be arc-shaped, and the sealing protrusion 5 and the sealing groove 6 are interference fit, which can enhance the sealing effect when used; the inner side of the sealing plate 3 is provided with a mounting groove 14, and the outer side of the sealing sleeve 4 is provided with a mounting protrusion 15, which is clamped in the mounting groove 14, so that the sealing sleeve 4 is convenient to install when in use.
[0021] From the above description, it can be seen that the utility model has the following beneficial effects: when in use, the connection between the cover plate 1 and the side plate 2 is tightly fitted and sealed by the engagement of the sealing protrusion 5 and the sealing groove 6 and the cooperation of the sealing gasket 7, and the busbar connection is sealed by the sealing sleeve 4 installed between the sealing plates 3, thereby reducing the phenomenon of water infiltration into the shell.
[0022] Example 2: Please refer to Figures 1 to 3 As shown, on the basis of the first embodiment, the utility model provides a technical solution: a heat dissipation pipe 11 is arranged on the inner side of the cover plate 1, a ventilation box 8 is arranged on the outer side of the cover plate 1, a ventilation fan 9 is arranged on the inner side of the ventilation box 8, and an air vent 10 is opened on the surface of the cover plate 1 at the position corresponding to the ventilation box 8. The ventilation box 8 and the heat dissipation pipe 11 are interconnected through the air vent 10, the heat generated by the busbar is absorbed by the heat dissipation pipe 11, and the air flow generated by the operation of the ventilation fan 9 passes through the heat dissipation pipe 11, so as to quickly take away the heat for heat dissipation; a heat dissipation carbon fiber layer 12 is arranged on the outer surface of the heat dissipation carbon fiber layer 12, and a heat dissipation graphite film 13 is arranged on the outer surface of the heat dissipation carbon fiber layer 12, and the heat dissipation graphite film 13 and the heat dissipation carbon fiber layer 12 absorb and quickly guide the heat dissipation pipe 11; both ends of the heat dissipation pipe 11 are fixed on the inner wall of the cover plate 1, and the heat dissipation pipe 11 is equidistantly installed on the cover plate 1, so as to ensure closure during use, thereby reducing the entry of external dust, moisture, etc. into the shell.
[0023] By adopting the above technical solution, when in use, the heat dissipation pipe 11 is fixed on the inner wall of the cover plate 1 and fits between the busbars. The heat generated by the busbars is absorbed by the cooperation of the heat dissipation carbon fiber layer 12 and the heat dissipation graphite film 13.

[0024] The working principle and use process of the utility model are as follows: when in use, the busbar is installed between the heat dissipation pipes 11, and then the side panels 2 are placed between the cover panels 1, and the sealing sleeve 4 is sleeved on the end of the busbar. The sealing plate 3 in the side panel 2 is clamped and pressed on the outside of the sealing sleeve 4 through the mounting groove 14 and the mounting protrusion 15. When the cover panels 1 are connected, the sealing protrusion 5 and the sealing groove 6 are clamped, and the sealing gasket 7 is used to strengthen the seal. When in use, the heat generated by the busbar is absorbed by the heat dissipation graphite film 13 and the heat dissipation carbon fiber layer 12 and quickly guided to the heat dissipation pipe 11. At the same time, the airflow generated by the operation of the ventilation fan 9 passes through the heat dissipation pipe 11, thereby quickly taking away the heat for heat dissipation, and avoiding dust and the like from contacting the busbar while ensuring heat dissipation.
