Through setting up insulating casing 31, it can prevent to rotate electrically conductive pass connecting piece 3 with dwang 1 directly switches on. In addition, the insulating shell 31 can prevent the positive and negative electrode circuits from being communicated with each other, thereby avoiding the exposure of wires or conductive structures and improving the sealing property and the aesthetic property.
With continued reference to fig. 1 and fig. 2, the insulation shell 31 includes a first insulation shell 311 and a second insulation shell 312 sleeved on the rotating shaft 21. The first insulating shell 311 and the second insulating shell 312 cooperate with each other to form a receiving cavity, and the receiving cavity is used for receiving the sleeve end of the connecting element 3.
As shown in fig. 1 and 2, a conductive sheet 32 is half-coated inside the insulating case 31. That is, at least a portion of the conductive sheet 32 passes through the insulating case 31 to be connected to an external electrode. In this embodiment, one end of the conductive sheet 32 is covered in the second insulating case 312, and the other end thereof penetrates through the second insulating case 312.
