Moreover, the wires may also age, wear, have poor contact, or break, thus affecting the stability and safety of the entire system. Therefore, it is necessary to improve it.

This design does not require the use of complex wire harness connections during the installation process, thus simplifying the entire installation process and shortening the time required for installation. Through this wire harness-free connection method, not only the installation convenience is improved, but also the connection stability and reliability are significantly enhanced.

The wire harness-free connection method adopted in the present utility model allows the user to simply align the pin 111 with the socket 22 and insert it gently to complete the connection, without the need for complex wiring operations. In addition, due to reasons such as bending, pulling or vibration of the wire harness in the traditional wire harness connection method, it is easy to cause problems such as poor contact or broken wires, thus affecting the normal operation of the equipment. The design of the pin 111 and the socket 22 in the present utility model has a stable connection relationship, which can effectively avoid the risks brought by poor contact or broken wires and ensure the reliable operation of the equipment.
