spring pin Characteristics Common structure of spring pin spring pin contact principle Characteristics
Common internal structure of spring pin Structure Ball beads structure Sloping structure Perforated structure Claw structure Contact impedance ≤ 10mΩ ≤ 30mΩ ≤ 50mΩ ≤ 5mΩ Long service time 10000+ 10000+ 10000+ 500+ Recommended working current 10A max 10A max 10A max 10A max Contact stability ★ ★ ★ ★ ☆ ★ ★ ★ ☆ ☆ ★ ★ ★ ☆ ☆ ★ ★ ★ ★ ★ Processing cost ★ ★ ★ ☆ ☆ ★ ★ ☆ ☆ ☆ ★ ★ ☆ ☆ ☆ ★ ★ ★ ★ ☆ Main application areas Mainly used for charging and condition with certain requirements for vibration and shock Mainly used for charging or signal transmission of Consumer electronics Mainly used for signal transmission or grounding antenna,etc. Mainly used high-frequency,anti-instantaneous,the situation which high-reliability is required,such as base stations,military industries,vehicles. Remarks The beads increase the internal contacts,the contact is more stable,and the more needle space is required The most commonly used structure on the market The space is smaller,but the contact is not stable,the current is easy to run through the spring,and it is not recommended for charging The needle and the needle tube have multiple contacts to increase the contact stability
