Frequently Asked Questions
Q What is a bridge-riveted 2 springs 18650 battery connector?
A A bridge-riveted 2 springs 18650 battery connector is a contact component that mechanically rivets two steel springs onto a stamped metal base using an automated bridge-riveting process. This design ensures the springs are permanently secured, preventing detachment during use and providing stable electrical contact for 18650 lithium battery applications.
Q What are the key advantages of fully automated production for these connectors?
A Fully automated production eliminates quality inconsistencies caused by manual handling, ensuring every unit meets the same strict dimensional and structural standards. With over 40 dedicated self-developed intelligent machines, we achieve a daily output of more than 2 million sets, delivering consistent verticality, flat surfaces, and reliable spring retention at scale.
Q What corrosion resistance options are available for the 18650 battery contact springs?
A We offer multiple solutions based on corrosion resistance grades, including 24-hour, 48-hour, and 72-hour neutral salt spray test options. The standard model (177L) passes the 24-hour salt spray test. Each plated batch must also pass a solderability test checkpoint to ensure consistent surface quality and long-term performance.
Q What environmental certifications do these battery connectors comply with?
A These 18650 battery connectors comply with both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations, ensuring they meet international environmental and safety standards for use in consumer electronics and industrial battery applications worldwide.
Q What materials are used in the construction of the 177L model connector?
A The 177L model is constructed using SPCC (cold-rolled carbon steel sheet) for the stamped base and steel wire for the coiled springs. The entire assembly undergoes nickel plating as the surface treatment, providing enhanced corrosion resistance, improved electrical conductivity, and better solderability for automated assembly processes.
Q How do these connectors support smooth automated battery assembly?
A The bridge-riveted design ensures springs never detach during handling or assembly, while the high verticality and consistently flat metal surfaces allow pick-and-place machines and automated assembly lines to position and install connectors with precision. The uniform geometry of each unit minimizes jamming or misalignment in automated equipment, improving overall production efficiency.
