[0026] When working, the staff selects the appropriate number of electric connection pieces 3 according to the position of the external switch, and then controls the movement of each electric connection piece 3 relative to the electric connection structure according to the position of the external switch, so that the electric connection piece 3 is connected with the switch one by one after the position adjustment is realized, and then the electric connection piece 3 is fastened with the electric connection structure through the fixing structure 5.
[0027] By allowing the electric connection piece 3 to be movably arranged relative to the electric connection structure, the electric connection piece 3 can be correspondingly arranged and the position of the electric connection piece 3 can be adjusted according to the actual number and position of the switch, thereby facilitating cost reduction and allowing the electric connection piece 3 to be flexibly moved and connected with the external switch.
[0028] In the embodiment, the electric connection structure includes a conductive groove 41 arranged in the first connecting piece 2, the fixing structure 5 includes a screw and a nut, the electric connection piece 3 has a lock hole 31, the screw is arranged in the lock hole 31, the electric connection piece 3 is slidably arranged in the conductive groove 41 by the screw, and the nut is screwed with the screw to fasten the electric connection piece 3 and the conductive groove 41.
[0029] That is, the electric connection piece 3 is slidably arranged in the conductive groove 41 by the screw, thereby realizing the position adjustment of the electric connection piece 3, and when the electric connection piece 3 needs to be removed, the screw can be pulled out of the conductive groove 41. Through the scheme of the embodiment, the disassembly and position adjustment of the electric connection piece 3 are convenient.
[0030] It should be noted that the electric connection piece 3 can be strip-shaped / plate-shaped as in the embodiment, or can be a shape bent multiple times. If the first connecting piece 2 and the switch are not located in the same vertical plane, a bent electric connection piece 3 can be used.
[0031] Specifically, the first connecting piece 2 is made of metal, the first connecting piece 2 is covered with an insulating layer 21, and the electrically conductive structure is exposed to the outside.
[0032] That is, the insulating layer 21 covers the first connecting piece 2 except for the electrically conductive groove 41, and the electrically conductive groove 41 realizes electrical conduction with the electrically conductive piece 3 through a screw.
[0033] In the embodiment, the connecting module 1 includes a second connecting piece 11, one end of the second connecting piece 11 is connected with the output end of the general switch, and the other end of the second connecting piece 11 is in electrical conduction with the first connecting piece 2.
