Products introduction
With the advancement of industrial technology, the safety and reliability of electrical appliances have become increasingly important, placing ever-higher demands on the permanent connections of Brazed Silver Contacts, thermal components, magnetic components, and conductive connectors. As a key process in the low-voltage electrical appliance manufacturing industry, brazing plays an increasingly important role. Silver-based solder offers excellent processing performance, including excellent wettability and gap-filling properties. It also features a low melting point, corrosion resistance, good conductivity, high mechanical strength, and excellent plasticity.
Features of Welded Contacts
Resistant to Electrical Wear: Welding Contacts maintain their shape and function under prolonged arc exposure, minimizing performance degradation due to electrical wear.
Resistant to Fusion Welding: When current flows, Button Silver Contacts resist fusion welding, preventing the contact surfaces from melting and sticking due to high temperatures, maintaining contact reliability.
Conductivity: Brazed Electrical Contacts offer excellent electrical conductivity, ensuring smooth current flow and reducing energy loss.
Low Contact Resistance: Welding Electrical Contacts have very low contact resistance, minimizing energy loss during current flow, improving the efficiency of electrical equipment. Good stability: The welding contact can maintain stable performance under various environmental conditions, including temperature changes, humidity changes, etc.
commonly used welding methods
1. Resistance Brazing: The Welding Contact resistance between the silver contact and the contact bridge is used to generate heat through a large current, so that the two are brazed together. Flux must be added during welding.
2. Flame Brazing: The Button Silver Contacts and the contact bridge are melted and welded together by the brazing material using flame heating.
3. Resistance Spot Welding: The resistance heat generated by the high-frequency current passing through the workpiece and the Brazed Electrical Contacts surface is used to heat the weldment to a local melting state, forming a molten core. The power is then turned off, and the weld solidifies and crystallizes under pressure to form a dense weld point, so that the silver contact and the contact bridge are welded together.
Welding Electrical Contacts are the heart of electrical appliances, and the quality of their welding has a great influence on electrical performance. At present, research related to welding, such as welding equipment, welding methods, and welding processes, is constantly deepening, among which improving the stability, reliability, energy saving, and automation of welding is its research direction.
