Electrical Bi-metal Contact Rivets
Products Description
Electrical Bi-metal Contact Rivets are a type of electrical contact rivet composed of two or more composite metal materials, typically mechanically bonded to a copper or brass substrate using a precious metal contact material (such as AgNi, AgCdO, AgSnO₂, AgCuO, etc.).
This structural design combines conductivity, arc resistance, and cost control, making it the most economical and efficient contact solution in electrical control systems.
The product plays the following key roles in circuit switching:
Current conduction: Ensures stable high current flow, reducing temperature rise and energy consumption.
Arch resistance: Resists arc erosion during frequent interruptions, extending device life.
Mechanical fixation: Achieves a high-strength structural bond through riveting, preventing loosening and displacement.
Reduced manufacturing costs: Replaces all-precious Electrical Contact Points with a composite structure, balancing cost and performance.
Innovative Structural Design
Head Arc Design
The contact head adopts an R-shaped arc surface structure, increasing the Silver Electrical Contact Rivets area, reducing concentrated contact pressure, and lowering localised heat generation.
Anti-rotation Groove Design
Micro-shaped anti-rotation grooves are set on the substrate surface to enhance the assembly firmness with plastic components and prevent loosening caused by vibration during equipment operation.
Lightweight Design
Without compromising mechanical strength, the Electrical Fittings Bi-metal Silver Contact Point structure is optimised, reducing weight by 10% to meet the lightweight requirements of new energy equipment.
Details Reveal the Truth: A Silent Commitment to Quality Control
Mirror-like Working Surface
Smooth, flawless contact surfaces ensure maximum effective contact area, significantly reducing contact resistance and initial temperature rise.
Precise Dimensional Tolerances
Strict dimensional control guarantees perfect compatibility with automated assembly lines, enabling precise application of riveting force and ensuring consistent assembly quality for every Composite Rivet Contact.
Burn-Free, Crack-Free Edges
Clean, crisp edges eliminate the risk of short circuits caused by burrs and reflect the maturity and stability of our molding process.
Clear Identification
Laser marking can be applied to Custom Electric Bimetal Rivets upon request, enabling batch traceability and providing data support for your quality management.
Application Value – Infusing Your Equipment with Reliable Connectivity
Enhancing Equipment Reliability
Our Silver Cadmium Oxide electrical contact rivet significantly reduces the failure rate of electrical equipment through superior arc resistance, abrasion resistance, and material transfer resistance. In critical applications, this increased reliability directly translates into production continuity and safety.
01
Extending Maintenance Cycles
Compared to traditional single-metal contacts, our products typically offer a service life 2-3 times longer under the same operating conditions. This results in longer maintenance intervals and significantly reduced total lifecycle maintenance costs for the equipment.
02
Optimizing System Performance
Stable Bi-metal Contact Point Rivets for Switch resistance translates to lower energy consumption and more consistent electrical performance. For precision control equipment, this stability directly translates into improved control accuracy and response speed.
