1. Waterproof, moisture-proof, rain proof, sun proof and anti-corrosion 2. Flame retardant, anti-oxidation and environmental protection (all products are from green production lines) 3. Improve the production process: connectors simplify the assembly process of electronic products and also simplify the batch production process 4. Easy maintenance: In case of failure, it is not necessary to clamp and break the cable, electric plastic sleeve, etc., but to unscrew both ends of the waterproof connector. It is very convenient for the maintenance of LED, solar energy, geothermal and other waterproof products 5. Improve the flexibility of design. The use of connectors gives engineers greater flexibility in designing and integrating new products and using components to form systems
