Copper Socket Spring - Wholesale - Price - Supplier Socket springs are connection devices used for electrical equipment requiring grounding, primarily functioning to secure the plug and ensure electrical conductivity. This requires the socket spring to have excellent electrical conductivity, followed by good elasticity and flexibility. The force of the spring's fit with the plug should be neither too tight nor too loose, allowing for secure holding of the plug while also being easily removable. Additionally, it needs to have good resilience, withstand repeated insertion and removal, and its elasticity and resilience should degrade within controlled limits, with the national standard being able to endure 40,000 cycles of insertion and removal. Moreover, the socket grounding spring must not rust, be resistant to oxidation and electrical arc formation, as these can all lead to a decrease in conductivity. Common materials include brass, beryllium copper, red copper (also known as purple copper), and stainless steel, with the manufacturing process being stamping, an efficient production method. It uses compound molds, especially multi-station progressive dies, allowing multiple stamping operations to be completed on a single press, from coil opening, leveling, cutting to forming and finishing, achieving full automatic production. Socket springs are a critical element directly affecting the performance of the socket, and their product quality and performance are crucial; they cannot be overlooked.
