The conductive structure of the present application can realize both sealing and conductive functions, and integrates the sealing structure and the conductive structure, which can reduce the space occupied by the motor shaft 6.

[0040] In addition, in the embodiments of the present application, the conductive beams 4 are separated by the sealing element 1, so that the conductive beams 4 cannot be gathered together due to oil adsorption, and the contact between the conductive beams 4 and the motor shaft 6 is reduced, thereby reducing the conductive effect.
