Beryllium Copper Flat Spring

The Fusion of beryllium copper flat springs "Superelasticity" and Silver Contacts' "Conductivity" The core value of this component lies in the "directional complementarity of material properties": Beryllium copper (BeCu) achieves "superelasticity" (elastic limit > 1380 MPa, twice that of phosphor bronze) through aging strengthening, maintaining constant elasticity during repeated deformation; silver contacts (Ag alloy) fulfill their conductive role with low resistance (< 3 mΩ) and high wear resistance. The two are precisely riveted together to form an integrated "elastic body-conductor" structure, solving industry pain points such as "insufficient contact pressure due to spring force decay" and "poor contact caused by assembly errors."

2. Key Feature Analysis

Dynamic Elastic Stability: The flat spring adopts a "variable cross-section arc design" (thick in the middle and thin at both ends). After optimisation by finite element simulation, the elastic force attenuation is <3% after 100,000 cycles of loading (±0.5mm deformation) (compared to >15% for ordinary springs);

Conductivity-Elastic Synergy: The difference in thermal expansion coefficients between Beryllium Copper Stampings and silver contacts is <1.5×10⁻⁶/℃. No stress cracking occurs at the interface after riveting. Conductivity fluctuation is <5% within the temperature range of -60℃ to 150℃;
