Shielded Spring Contacts for High-Speed Data Connectors & Telecom Equipment
Beryllium Copper Stamping
Tingfeng Hardware provides shielded spring contacts specifically for high-speed data connectors and telecom equipment, manufactured from beryllium copper through precision stamping processes. These spring contacts are used for EMI shielding and grounding connections in high-speed backplane connectors, data center switches, and telecom equipment, ensuring high-speed signal integrity.
With 16 years of precision manufacturing experience, our products comply with ISO 9001 and RoHS standards, with custom designs supported per customer drawings.
Product Overview
Shielded spring contacts in high-speed data connectors and telecom equipment are critical components for ensuring signal integrity. As data rates increase to 25Gbps and beyond, the impact of electromagnetic interference on signal quality becomes increasingly significant.
Our beryllium copper shielded spring contacts effectively suppress electromagnetic leakage and crosstalk by providing multiple low-impedance grounding paths around connectors. Beryllium copper (conductivity approximately 22% IACS) ensures low-impedance grounding, with gold plating providing stable contact interfaces and oxidation resistance.
The spring contact design provides 0.5-3.0mm compression range, accommodating various gaps between PCBs and shielding covers. Each spring contact undergoes 100% force testing and dimensional inspection, suitable for high-speed backplane connectors, data center switches, core routers, and other telecom equipment.
