Product Description
Precision Stamped Battery Contacts – Low Resistance Phosphor Bronze for Portable Medical Devices
Tingfeng Hardware provides precision stamped battery contacts specifically designed for portable medical devices, manufactured from high-conductivity phosphor bronze through precision stamping and selective gold plating processes. The contacts offer ultra-low contact resistance (≤5mΩ) and stable elastic force, ensuring reliable battery connections for medical devices. With 16 years of precision manufacturing experience, products meet the stringent requirements of medical devices for component consistency and long-term reliability.
Product Overview
Portable medical devices (such as glucose meters, portable monitors, and infusion pumps) have extremely high requirements for battery connection reliability. Our precision stamped battery contacts use phosphor bronze substrate with gold plating surface treatment, controlling contact resistance stably below 5mΩ, ensuring stable power supply under low-voltage, micro-current operating conditions. The contacts feature precisely designed force values (0.5-1.5N), maintaining reliable battery-to-PCB connection even during device drops or vibration. Each contact undergoes 100% contact resistance testing and force inspection, suitable for battery compartment connections in various portable medical devices.
