Precision Stamped Connector Coiled Spring Pins

These cylindrical metal components feature uniform longitudinal slots along the side walls, serving as male contacts in electrical connector systems. The coiling process imparts radial elasticity to the parts. When mated with female sockets, this structure generates a stable normal force to maintain low contact resistance, effectively preventing signal transmission interruptions. They are widely used in precision connection scenarios for communication equipment, automotive electronics, and industrial control.

The manufacturing process employs high-speed progressive die continuous stamping and coiling forming techniques, gradually processing strip metal materials into tubular structures. Key controls include outer diameter consistency, slot gap, and overall straightness. To address springback and deformation issues common in thin-walled tubes during high-speed forming, production relies on high-precision molds and high-speed presses with 0.005mm accuracy. Optical image measuring instruments are used for 100% inspection of micro-features to ensure dimensional stability in batch deliveries.

The factory holds dual IATF 16949 and ISO 9001 certifications. We support the processing of conductive and elastic materials such as brass, phosphor bronze, and stainless steel, and offer surface treatments including gold, silver, nickel, and tin plating to meet corrosion resistance and low impedance requirements. Quotations are evaluated based on specific 3D drawings, material grades, plating specifications, and expected order volumes, making them suitable for precision connection needs with strict requirements for electrical performance and mechanical life.
