In the electrical connection sector, the riveting of Brass Stamping Terminals and silver contacts has emerged as a core supporting technology for low-voltage electrical appliances, automotive electronics and many other industries, thanks to its key advantages of reliability and cost-effectiveness. It quietly safeguards the stable operation of various electrical equipment. As the base of electrical terminals, brass delivers a solid structural foundation for connecting components with its excellent mechanical strength and machinability. Silver contacts, on the other hand, act as the critical core for current transmission due to their outstanding electrical conductivity and oxidation resistance. The precision riveting process that combines the two not only cuts down the cost of precious metals but also guarantees the electrical performance of key contact points, making it a widely recognized standard solution in the electronics and electrical industry.
With the advancement of industrial automation, the manufacturing process for 16A Switch Socket Contacts riveted with silver contacts has gradually evolved from traditional manual operation to automated production, greatly enhancing application adaptability. Conventional manual riveting relies on manual positioning and pressure control, making it only suitable for small-batch customized products. It is also prone to issues such as insecure riveting and contact offset, failing to meet the demands of large-scale production. Today, automated technologies including punch-type automatic riveting machines and in-mold automatic riveting are widely applied. Among them, in-mold automatic riveting can simultaneously complete stamping forming and contact riveting in multi-station progressive dies, significantly boosting efficiency. Meanwhile, the protective design of protective covers and adsorption devices further ensures production safety, providing efficient support for large-scale applications.
Scientific material selection is the key to enabling Brass Stamping Terminals riveted with silver contacts to adapt to diverse scenarios. Brass (H62/H65), with its moderate cost and qualified mechanical strength, is widely used in various conventional electrical terminals after tin plating. Phosphor bronze and beryllium copper are tailored for humid environments and high-load applications respectively, further expanding the application scope of the riveting technology. For contact materials, silver alloy series such as AgNi and AgSnO₂ suit different scenarios with their respective properties. The eco-friendly AgSnO₂ material is gradually replacing traditional cadmium-containing materials, aligning with the industry's environmental development requirements. Precise control of silver layer thickness further ensures stable current transmission across different application scenarios.
A standardized quality control system provides a solid guarantee for the extensive application of AgCdO12 contact rivet with brass terminals riveted with silver contacts. The industry abides by the core standard JB/T 4310-1999 Structural Types and Dimension Series of Riveted Silver-Copper Composite Contacts. Micron-level dimension inspection is achieved through image measuring instruments, projectors and other equipment, combined with performance tests such as four-probe conductivity scanning and temperature rise testing, as well as failure prevention methods like metallographic analysis. This ensures every set of riveted components meets the application requirements of different scenarios, effectively avoiding potential safety hazards such as poor contact and overheating.
At present, Brass Stamping Terminals have been deeply integrated into many key fields, serving as an important support for industrial upgrading. In automotive relays, components made of AgSnO₂ contacts riveted with brass terminals can withstand over 100,000 switching operations, ensuring the stable operation of automotive electrical systems. In smart electricity meters, the application of high-precision silver contact riveting guarantees long-term metering accuracy, providing reliable support for power metering. In high-current applications such as new energy vehicle charging guns, the riveted structure of multi-layer composite contacts effectively solves problems like overheating and unstable contact during high-current transmission, boosting the high-quality development of the new energy vehicle industry. In addition, this technology plays an irreplaceable role in smart homes, industrial automation equipment and other fields, becoming a core pillar of electrical connections.
With continuous technological innovation in the industry, Rivets Copper Contacts Assembly riveted with silver contacts are developing towards greater environmental friendliness, intelligence and precision. The application of silver-saving technology and intelligent production methods further reduces application costs and improves product consistency, laying a foundation for applications in more emerging fields. This perfect integration of material science, precision manufacturing and electrical performance has become an indispensable core technology in the electrical connection sector, continuously empowering the upgrading and iteration of electrical equipment across various industries.
