EV charging connector pins are used as conductive contact components in charging plugs, charging sockets and related electrical connection assemblies. These parts usually require accurate turning, stable surface quality and reliable dimensional control to match the connector structure.
The pins can be produced from copper alloy, brass or other conductive materials. Surface finishes such as nickel plating, tin plating, silver plating or other treatments can be selected according to the project requirement. The structure may include stepped diameters, grooves, holes, chamfers, rounded ends and other custom features.
CNC turning is suitable for this type of contact pin because it can control roundness, outer diameter, length and stepped details according to the drawing. For selected critical dimensions, tolerance can be controlled based on material, structure and process requirements.
These products are suitable for EV charging connector assemblies, charging socket parts, power connector components, electrical contact parts and custom conductive hardware.
