Precision Stamped Cylindrical Connector Pins

These cylindrical metal components typically serve as male pins or contacts within electrical connector systems, ensuring stable electrical conductivity between PCBs, wire harnesses, and terminals. The sidewalls feature longitudinal slots or cutouts that provide radial elasticity, generating appropriate normal force when mated with female sockets. This design maintains low contact resistance and prevents signal interruption.

Manufactured using high-speed progressive die stamping, strip metal is progressively formed into tubular structures. We strictly control outer diameter consistency, slot gap, and overall straightness. To address springback and deformation common in thin-walled tubing during high-speed forming, we utilize high-precision molds and high-speed presses with 0.005mm accuracy. Optical image measuring instruments are employed for 100% inspection of micro-features to guarantee dimensional stability in mass production.

Our factory holds both IATF 16949 and ISO 9001 certifications. We process conductive and elastic materials such as brass, phosphor bronze, and stainless steel, offering plating options including gold, silver, nickel, and tin to meet corrosion resistance and low impedance requirements. Quotes are based on specific 3D drawings, material grades, plating specifications, and order volumes. These pins are ideal for precision connectivity in communications equipment, automotive electronics, and industrial control systems.
