Electrical Contact Rivet
Products Description
Electrical contact rivets are precision electronic connectors integrating "conductive conduction, mechanical fixation, and wear-resistant contact." Their core value lies in the synergy of "low-resistance stable conduction" and "long-lasting wear-resistant contact." Unlike ordinary fasteners, our products focus on the core needs of B2B electronic and electrical scenarios:
Essential Attributes: They possess both "precision conductivity" and "mechanical fixation," serving as both "current conduction contacts" for electrical components (switches, relays, contactors) and "structural fixation carriers" for component assembly.
Core Features: Low contact resistance, high wear resistance and arc resistance, bimetallic metallurgical bonding, high dimensional accuracy, multi-specification compatibility, and full-process compliance, adaptable to all scenarios from micro-signal transmission to high-power current carrying, covering an operating temperature range of -55℃ to 120℃.
Product Advantages: Why are our rivets a more reliable choice?
Exceptional Conductivity and Arc Resistance
The contact layer uses our specially formulated silver metal oxides (such as AgSnO₂, AgNiO). Under the high temperature of an electric arc, the oxides decompose and absorb a large amount of heat, forming a stable molten metal pool, effectively suppressing material spatter and arc erosion.
Unparalleled Interface Bond Strength
Our core technology-solid-state diffusion welding-allows for atomic interdiffusion at the interface of the two metals under high temperature and pressure. This bond strength far surpasses traditional brazing or mechanical bonding.
Optimised Riveting Process and Stress Distribution
The rivet head shape, shank size, and chamfer design have all undergone precise mechanical simulation. This ensures that stress is evenly distributed to the substrate during riveting, preventing damage to fragile elastic components or insulating frames, while achieving a secure mechanical lock.
Lifecycle Cost Benefits
Superior resistance to welding and material migration translates to lower failure rates and longer product lifespan. Standardised dimensions and exceptional consistency significantly improve your automated assembly efficiency and reduce scrap rates. Overall, choosing our rivets greatly enhances the lifecycle value of your products.
Engineering Depth in Materials Science: Why Choose Copper Alloys and Special Plating?
Precise Selection of Copper Alloy Substrate
We use high-purity copper alloys (Cu-Be, copper-beryllium alloy). By precisely controlling the beryllium content (0.2-0.5%), we significantly improve the material's hardness and wear resistance while maintaining high conductivity.
Electrochemical Compatibility Design
In electrical systems, electrochemical corrosion can occur when different metals come into contact. Our rivets employ a special plating design to ensure electrochemical compatibility with common electrical connection materials (such as copper, aluminum, and steel).
Thermal Management Material Properties
Contact point heating is a common problem in electrical connections. Our material selection takes into account the matching of thermal expansion coefficients (17.2×10⁻⁶/°C) to ensure that the expansion coefficients of the rivets and contact surfaces are consistent when the temperature changes, thus avoiding loosening of the contact and increased resistance due to differences in thermal expansion.
Detailed Explanation: Excellence Stems from a Dedicated Focus on Key Aspects
Precision Interface Control
The contact surface employs a special geometric shape and texture design to optimise contact point distribution, reduce contact resistance, promote arc diffusion, and extend service life.
