EV Silver-Plated Spiral Spring Contact

This EV Silver-plated Spiral Spring Contact produced by our Lijinda factory is "made of highly elastic alloy wire, precisely wound and formed, and then a thick layer of pure Silver is formed on the surface through electroplating process, A conductive element used to provide continuous, multi-point, elastic contact between two rigid conductors. Its core value lies in that it solves the problem that rigid connections may loosen or generate stress in dynamic environments.Its spiral structure, like a spring with countless contacts, can continuously apply a steady contact pressure, even in the vehicle's driving bumps and temperature changes, can ensure that the current path is never interrupted. The silver-plated layer on the surface ensures extremely low contact resistance and excellent oxidation resistance under high current. As a highly reliable elastic bridge, it is directly related to the long-term reliability of high-voltage connectors and the safety of the entire vehicle.

Structure

The structure of our EV Silver-Plated Spiral Spring Contact is a precision mechanical system designed to achieve multi-point contact and elastic compensation. Its skeleton is a alloy wire (such as beryllium copper or tin bronze) with excellent elasticity and fatigue resistance, which is the basis for providing continuous contact pressure. Its "shape" is a precise helical tubular structure, which provides a large number of linear contact points and greatly increases the conductive area.Its coat is a layer of pure silver formed by electroplating; silver is one of the most conductive metals, which covers all contact points and ensures the lowest contact resistance.

Application scenarios

This EV Silver-Plated Spiral Spring Contact is the core component of all automotive high-voltage systems that require highly reliable dynamic connections. It is widely used in the connection of battery packs and cells in new energy vehicles, the internal connection of high-voltage distribution boxes (PDUs), charging interfaces (charging sockets), as well as the connection of power modules between motor controllers and on-board chargers (OBCs).
