Description
Custom Battery Contact Springs / Contact Fingers - High Precision Stamping
Precision Stamping Parts Overview

Custom battery contact springs are core connection components for smart portable devices, requiring high elasticity, low resistance, and durability. Tingfeng Hardware uses advanced spring materials like beryllium copper and titanium copper, with progressive die stamping and stress relief heat treatment, ensuring stable contact force after millions of cycles. SMT and through-hole packaging are available, meeting automated assembly needs of smart products. 15 years industry experience, supporting fully customized development according to drawings.

Product Description

Smart wearables and med-tech devices have stringent space and performance requirements for custom battery contact springs. Through FEA optimization of arm shape, contact force of 0.3N-1.5N is achieved within 0.5mm narrow space; multi-point contact design reduces resistance, supporting 3A continuous current. Surface options include gold or silver plating for various corrosive environments. Each spring undergoes 100% force testing, sorted by actual force ±0.1N before shipping, facilitating customer pairing. Custom design and development available based on customer specific space, current, and life requirements.
