Abstract:
Provided in the present application are a cover plate assembly, a stator, an electric motor, a compressor and a vehicle. The cover plate assembly is used for the electric motor, which comprises a lead, and the cover plate assembly comprises: a first housing provided with a first communication portion; and a second housing detachably connected to the first housing, wherein a sealing cavity and a second communication portion are jointly enclosed between the first housing and the second housing, and the first communication portion and the second communication portion are both in communication with the sealing cavity; and the second communication portion is used for allowing the lead to extend into the sealing cavity. By means of the present application, the sealing cavity is jointly enclosed between the first housing and the second housing, the connection between the lead and a wiring portion is located in the sealing cavity, and the sealing cavity can effectively prevent external media such as oil and refrigerant from penetrating into the connection between the lead and the wiring portion, such that an excellent sealing effect is achieved, and the situation where the insulation resistance of a stator of an electric motor drops sharply due to the penetration of media such as oil and refrigerant into the connection between a lead and a wiring portion is avoided, which is beneficial to ensuring the use performance and reliability of the electric motor.
