The middle outer walls of the plurality of moving contacts 4 are fitted and connected to the inner wall of the installation groove 2 via the two gaskets 8.

[0026] During operation, multiple moving contacts 4 are respectively inserted into the interior of the installation groove 2 by fitting two by two, and then two gaskets 8 are respectively inserted between the four moving contacts 4 and installed in the middle of the installation groove 2. The two gaskets 8 can be used to push the two moving contacts 4 at both ends to fit with one side of the installation groove 2, so that multiple moving contacts 4 are all clamped in the interior of the installation groove 2. Then the fixing bolt 6 is passed through the interior of the threaded hole 5 at the top, and then the fixing bolt 6 is rotated so that the fixing bolt 6 passes through the interior of a moving contact 4 and two gaskets 8, so that one end of the fixing bolt 6 is threadedly connected with the threaded hole 5 inside the other moving contact 4. The upper and lower moving contacts 4 are both fixed on the outside of the gasket 8, and then the moving contacts 4 are fixed at both ends of the installation groove 2 to ensure the stability of the structure. The moving contact 4 is an integral structure, which can not only increase the current that the moving contact 4 can bear, but also facilitate the installation and disassembly of the staff, reduce the time and energy consumed during assembly, and improve the assembly efficiency and practicality of the moving contact assembly.
