Product Description
Custom High-Conductivity Battery Springs with Plated Bronze for Low Resistance & Stable Current Transmission
1.Battery Spring Quick Detail
Tingfeng Hardware specializes in the precision manufacturing of high-reliability battery contact springs. We deeply understand the importance of battery connectors for stable power supply and device safety, offering full-range processing capabilities from Φ0.1mm ultra-fine wire to 1.2mm strip. We not only manufacture springs but also provide solutions to ensure excellent electrical contact performance, including material selection, plating optimization, and spring force design. With 15 years of experience, an IATF/ISO dual-certified system, and rapid mold response, we promise 48-hour functional sample delivery and 72-hour trial production start-up, serving as your reliable partner for battery connections in products like consumer electronics and wearables.
2.Battery Spring Product Description
Battery springs are crucial miniature components that ensure stable and safe power supply for electronic devices. As your technology partner, we specialize in integrating electrical requirements (low resistance, corrosion resistance) with mechanical requirements (stable contact force, long cycle life). Our services cover everything from single-point contact coil springs to complex multi-finger contact springs, using materials such as highly conductive phosphor bronze and beryllium copper, or high-elasticity piano wire and stainless steel, complemented by high-performance plating (such as gold and nickel plating). Through the integration of computer-controlled spring machines, precision stamping, and fully automated riveting and assembly, we ensure that every battery spring contact has consistent contact force, extremely low contact resistance, and excellent corrosion resistance, thereby enhancing the reliability and user experience of your end products.
3.Battery Spring Product Features & Advantage
|
Feature |
Advantage to You |
|
Electro-Mechanical Integrated Design |
Engineers concurrently consider conductivity and elasticity, optimizing materials and structure to achieve the best balance between low resistance and high-reliability contact force within limited space. |
|
Precise & Consistent Forming Process |
Employs computerized spring machines and precision stamping to ensure high consistency in contact strip shape, bend angles, and contact point position, guaranteeing battery connection stability. |
|
Targeted Surface Finish Solutions |
Depending on the working environment (such as humidity and sweat), select the appropriate plating (high salt spray nickel, gold, or tin) to significantly improve corrosion resistance and solderability, extending the service life. |
|
Rapid Customization & Validation Cycle |
Supports very low-volume prototyping. Combined with rich experience in battery compartment design, we can quickly provide samples for assembly testing, accelerating your product development cycle. |
