Welded Silver Contact Machined Assembly
Products Description
The Welded Silver Contact Machined Assembly is an integrated conductive component formed by precision-machined copper substrates and silver contacts using a highly reliable welding/brazing process. This product not only handles the main current transmission but also serves as a key component for arc control, contact pressure transmission, heat dissipation, and long-term mechanical stability.
Product Structure Disassembly
- Copper-based support layer: Precision Welding for Copper Parts uses high-conductivity copper material, integrally stamped, with pre-drilled mounting holes, functional clearance grooves, and structural reinforcing ribs. It serves as the main path for current conduction and the mechanical mounting carrier.
- Silver-based contact layer: As the core functional component of Welded Ag Contact Assemblies, it is fixed to the designated working surface of the copper substrate through metallurgical bonding. It serves as the direct contact area for switching operations, undertaking the core functions of arc extinguishing, ablation resistance, and low-resistance conduction.
The overall structure has no extra redundant assembly parts, making it a simplified, highly reliable electrical contact component, fully conforming to the structural design logic of Brazing Silver Electrical Contacts.
Product Application Advantages
High-voltage DC Scenarios
DC arcs are more difficult to extinguish than AC arcs because there is no current zero-crossing point. The arc erosion resistance of the silver alloy contacts and the heat dissipation capacity of the copper substrate work together to ensure that the Electrical Contact Assembly with Silver Welded Tip can complete the disconnection under DC high-voltage conditions without contact welding.
High-Frequency Operation Scenarios
In energy storage converters or charging piles, contactors may face frequent operation. The welded structure of Circuit Breaker Contact Brazing Assemblies offers superior impact resistance compared to riveted structures, preventing loosening under high-frequency mechanical impacts.
Wide Temperature Range Scenarios
From the low temperatures of northern winters to the high temperatures inside equipment, the reliability of the Brazing Silver to Copper structure has been proven in numerous automotive and outdoor devices. The similar coefficients of thermal expansion between copper and silver result in lower thermal stress at the interface during temperature changes.
Packaging and Transportation
| Inner Packaging | Each Brazed Electrical Contact is individually packaged in an anti-static plastic box to prevent scratches on the silver contacts and oxidation of the copper substrate. |
| Middle Protection | The plastic box is filled with a cushioning bubble bag to prevent dimensional deformation caused by vibration and impact during transportation, fully protecting the structural precision of Brazed Contacts for MCCB. |
| Outer Packaging | Thickened five-layer corrugated cardboard box, wrapped with a waterproof film, suitable for long-distance sea and land transportation, providing full protection against moisture corrosion for the Contact Joining Brazing molding components. |
| Shipping Packages | Each box includes a batch test report, material compliance certificate, and packing list, fully recording the test data for each batch of Contact Welding finished products. |
| Logistics Solutions | We can arrange sea and air freight with the customer's designated freight forwarder. Small samples are shipped directly via international express to ensure rapid delivery of Brazed Contacts to overseas R&D and production lines. |
