Precision spring clip
Precision metal shrapnel is a core elastic component that enables battery conduction, grounding, and signal contact in small digital and smart wearable devices, widely used in TWS earphones, smart wristbands, portable compact electronic modules, and other products. Leveraging years of expertise in precision metal stamping, Jingrui has independently developed the SPN series of standardized positive‑pressure precision shrapnel, establishing a comprehensive specification‑selection matrix. The entire series is available in two base materials—stainless steel and copper—covering product heights from 3.50 mm to 6.80 mm, with multiple ranges of elastic travel. Optional features include scratch‑resistant contacts and simply supported reinforced structures. Integrated one‑step stamping combined with gold‑plated contacts ensures long‑lasting, stable elasticity and low contact resistance, making it compatible with automated SMT assembly. With 119 standard stock specifications, it meets the internal stacking requirements of most thin‑and‑light devices, offering outstanding cost‑effectiveness and supporting a wide range of conventional electrical‑contact applications in consumer electronics.
