[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a spring is sleeved on the terminal between the conductive block and the threaded sleeve.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Buffering effect: The spring can play a buffering role during the operation of the motor, reduce the contact impact caused by vibration or other external forces, protect the conductive block and the motor surface, and extend the service life of the equipment.

[0010] Maintain good contact: The presence of the spring can ensure that the conductive block always maintains good contact with the motor surface. Even if there is a slight position change during the operation of the motor, the elasticity of the spring can adjust and maintain the appropriate contact pressure to ensure the accuracy of insulation status detection.

[0011] Adaptability: The spring design can adapt to motor surfaces of different sizes and shapes, improving the versatility and applicability of the device.

[0012] Simplified installation: Since the spring is directly mounted on the terminal, the installation process is relatively simple. Operators do not need additional tools or steps to install the spring, reducing the complexity of the installation process.
