Products Description
Brazing Electrical Connections is based on advanced working principles and uses resistance heat to achieve precise welding. During the production process, it has undergone multiple rigorous performance testing stages. The welding strength test ensures that the connection is as solid as a rock, the conductivity test ensures that the current flows smoothly, and the corrosion resistance evaluation makes it fearless of harsh environments. With our persistent pursuit of quality, professional technical services and the spirit of continuous innovation, we not only lay the foundation for excellent quality for our products, but also provide customers in various industries with comprehensive and highly reliable solutions.
Material Properties
Contact Material
Typically silver or silver-based alloys (such as AgCdO, AgSnO2, etc.) are used for the brazing of Electrical Contact. These materials possess high conductivity, excellent resistance to arc erosion, and resistance to welding.
Substrate Material
Primarily high-conductivity copper or copper alloys (such as copper, brass, bronze), providing structural support and the main current path for the Electrical Connection Brazing.
Silver-based Brazing Metal
As a filler metal, its composition (such as silver-copper eutectic alloys) is carefully designed to ensure melting at temperatures below the melting point of the base material, exhibiting good fluidity, wettability, and the strength and conductivity of the brazed joint for Electrical Contact Resistance Welding.
Working principle of the product
Contact point current conduction
During the welding process, the current is conducted from the power source to the workpiece to be welded through the Low Resistance Contact Brazing.
Electrode crimping
The electrode applies a certain pressure to the welding part to ensure that the current passes through the contact point and maintains a stable contact quality to prevent excessive resistance or insufficient melting.
Welding process control
Welding equipment needs to accurately control factors such as current, voltage, pressure and time to ensure welding quality while avoiding overheating or weak welding for Electrical Connection Brazing.
Cooling and solidification
After welding is completed, the solder joint gradually solidifies through the cooling process, and finally forms a strong connection for Electrical Contact Resistance Welding.
Industry Application Cases
| Low-voltage circuit breakers | Brazing of Electrical Contacts are used for connecting main contacts, arc contacts, and conductive rods, requiring them to withstand the enormous electrodynamic repulsion and thermal shock of short-circuit currents. |
| AC contactors and magnetic starters | Electrical Connection Brazing is used for connecting main circuit contacts, needing to cope with the arcing and mechanical shocks generated by frequent switching, and handling currents of hundreds of amperes. |
| Disconnecting switches and load switches | Electrical Contact Resistance Welding is used for connecting current-carrying contacts, requiring them to continuously carry rated current and maintain low contact resistance. |
