What are the advantages of contact terminals with wire spring structure

The terminal structures of connector sockets mainly include wire spring type, crown spring type, cantilever type, claw spring type, and torsion spring type. Among them, the interior of the wire spring terminal is a hyperbolic wire spring structure, which is made up of several elastic gold plated beryllium copper wires that are uniformly wound at a certain angle. When the pin is inserted into the wire spring hole, these elastic copper wires tightly wrap around the pin, forming a multi wire contact. A pair of pinholes is equivalent to several pairs of ordinary leaf spring type pinholes used in parallel, achieving advantages such as low and stable contact resistance, small insertion and extraction force, and low contact wear. The product's insertion and extraction life can reach up to 100000 times, and it is not easy to produce instantaneous breaks in strong vibration and impact environments, resulting in better reliability. The connectors that use wire spring hole terminals have been widely used in industries such as industry, energy, automotive electronics, and semiconductors.
