AI Technical Summary
Existing terminal blocks lack a waterproof structure, allowing water to enter the wiring and damage the circuit. Furthermore, the connectors are prone to loosening, leading to open circuits.
A waterproof terminal block plastic part was designed, including a terminal housing, a waterproof rubber sleeve, a support spring, and a waterproof cotton sleeve. The combination of the waterproof rubber sleeve and the waterproof cotton sleeve effectively waterproofs the terminal block, and the cooperation of the push plate and the support spring facilitates the insertion of the connector.
It achieves effective waterproofing of the terminals, preventing moisture from entering the wiring, while maintaining the stability of the connection and avoiding loosening and open circuits.
