China Suppliers Factory: Fully Automated Production of Reliable Bridge-Riveted AA Battery Connectors
Product Application
Application
We rely on self-developed intelligent production equipment as the core, adopting bridge riveting technology to ensure fully automated and highly consistent spring assembly. More than 40 machines operate in coordination, supporting a robust daily delivery capacity of over 2 million sets.
Application
Using bridge riveting technology, the spring remains secure and never loosens. Strict control over verticality and flatness provides reliable support for automated assembly.
Application
Every model of universal AA battery contact spring is developed through strict material and process selection, achieving tiered salt spray corrosion resistance of 24, 48, or 72 hours. Additionally, each plated batch is required to pass solderability testing to validate its performance.

Frequently Asked Questions
Q
What is bridge riveting technology and why is it used in AA battery connectors?
Bridge riveting technology is a specialized assembly method that securely fastens the spring to the contact base without loosening over time. It ensures the spring remains firmly in place during repeated battery insertions and removals, providing consistent electrical contact, high verticality, and superior flatness — all critical for reliable automated assembly.
Q
What models are available for the universal AA battery connector?
Two models are available: 027D and 027L. The 027D measures 14×12mm and the 027L measures 29.6×12mm. Both are made from SPCC steel combined with steel wire and feature a nickel-plated surface treatment.
Q
What certifications do these battery connectors comply with?
All universal AA battery connectors comply with RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) eco-certifications, ensuring they meet international environmental and safety standards.
Q
What is the salt spray corrosion resistance level of these connectors?
The universal AA battery contact springs are developed with tiered salt spray corrosion resistance options of 24, 48, or 72 hours, depending on the model and specification. The standard model passes a 24-hour neutral salt spray test. Additionally, every plated batch undergoes solderability testing to validate its performance.
Q
What is the daily production capacity for these AA battery connectors?
With over 40 dedicated automated machines operating in coordination, the daily production capacity exceeds 2 million sets. The fully automated, hands-free bridge riveting process ensures consistent quality and high output to meet large-scale delivery requirements.
Q
Are these battery connectors suitable for automated assembly lines?
Yes. These connectors are specifically engineered for automated assembly environments. The bridge riveting process guarantees strict control over verticality and flatness, which are essential parameters for seamless integration into automated production lines. Their consistent dimensions and secure spring retention make them highly reliable for high-volume manufacturing applications.
