Products Description
The AgCdO Solid Silver Contact Rivet is a core component designed for high-end circuit switching scenarios. It is primarily used as the switching moving contact in high-end relays and industrial control relays, and is also widely used in various high-load power switches and emergency stop switches. Thanks to its excellent conductivity, this product ensures stable switching under high current conditions; however, due to its higher material cost, it is typically used in scenarios with stringent reliability requirements.
Material Advantages
Silver Cadmium Oxide Contact features a uniform metal oxide dispersion structure, which significantly improves arc erosion resistance and extends contact life.
Compared to pure silver contacts, AgCdO contacts offer over 40% improved resistance to soldering, avoiding the risk of contact adhesion under high current conditions.
The stable conductivity of Electrical Spring Contact reduces contact temperature rise and minimizes energy loss.
Manufacturing Process
Powder Metallurgy Molding
High-precision molding technology ensures uniform and dense silver cadmium oxide powder.
Vacuum Sintering
High-temperature sintering under a vacuum of 10⁻³Pa eliminates internal porosity in Silver Alloy Contacts, increasing material density.
Precision Cold Heading
The riveted structure of Electrical Spring Contacts is formed using CNC cold heading equipment, with coaxiality tolerance controlled within 0.02mm.
Surface Treatment
Electrolytic polishing is used, achieving a surface roughness Ra≤0.8μm, reducing the contact resistance of Monometal Contact Rivets.
Industry Application Cases
| Industrial Control | AgCdO Contacts can act as moving contacts in PLC output relays and industrial control contactors, handling current switching. |
| Power & Electrical | Monometallic Contact Rivets can act as main contacts in circuit breakers and disconnectors, providing arc resistance. |
| Home Appliances | Solid Rivet Contacts are used as load switch contacts in air conditioner compressor protectors and washing machine controllers. |
| Safety Equipment | Silver Cadmium Oxide Contacts serve as high-reliability operating contacts in emergency stop switches and safety relays. |
| Transportation Equipment | AgCdO Solid Silver Contact Rivets ensure stable contact under vibration in rail transit control relays. |
