What are Beryllium Copper Punch Contact Riveted Terminals?
Engineered for continuous duty in heavy-duty low-voltage switchgear and automated control panels, our Beryllium Copper Punch Contact Riveted Terminals deliver unwavering mechanical stability and low electrical resistance under high-frequency switching cycles. Fabricated from premium precipitation-hardened C17200 strip stock, these components combine exceptional spring resilience with secure mechanical riveting, preventing micro-motion wear and contact loosening during high-current surges. Operating as a direct-source manufacturing partner, we supply precision-machined electrical components built strictly to engineering blueprints, supporting global industrial distributors and assembly plants with stable volume production and stringent quality verification
Elastic Resilience & Spring Performance of Relay Movable Spring Riveting Assembly
Stress Relaxation Resistance
Retains over 90 percent of initial contact force after 1,000 hours of continuous operation at 125°C, preventing thermal runaway in confined electrical enclosures.
Fatigue Life Endurance
Withstands upward of 10 million repetitive deflection cycles without micro-cracking or plastic deformation, ensuring long-term operational integrity in dynamic relay architectures.
Yield Strength Optimization
Controlled heat treatment protocols transform raw copper-beryllium alloy into a high-tensile spring element capable of sustaining intense mechanical impact.
Friction and Wear Mitigation
Smooth stamped edge profiles minimize abrasive friction against mating contact blocks, reducing particulate shedding inside sealed switching chambers.
Typical Application Scenarios of Silver Contact Riveting Assembly
Industrial Circuit Breakers:
Integrated into main trip mechanisms and auxiliary switch modules of molded case circuit breakers (MCCB) for reliable mechanical latching.
Power Distribution Relays:
Deployed within heavy-duty control relays requiring persistent spring pressure and stable electrical pathways under continuous thermal loads.
Automotive Auxiliary Systems:
Functions as resilient current-carrying spring blades in under-hood power distribution boxes and cooling fan control units.
Industrial Automation Controllers:
Utilized in high-density contact blocks of programmable logic controller (PLC) output modules to maintain zero-resistance continuity.
Frequently Asked Questions about Relay Moving Spring Terminal Beryllium Copper
What is the base material of Relay Movable Spring Riveting Assembly?
The reference design uses beryllium copper for the stamped terminal, with C17200 specified for high-elasticity relay moving structures. The referenced C17200 specification lists 1.8–2.0% Be, 1200–1400 MPa tensile strength, and HV 380–420 hardness. Final grade and temper follow the approved drawing.
Why is C17200 suitable for Relay Moving Spring?
C17200 combines high mechanical strength with elastic behavior and electrical conductivity, making it suitable for thin stamped moving structures. For the referenced relay application, the material specification lists 1200–1400 MPa tensile strength and HV 380–420 hardness, providing a defined mechanical basis for spring-forming applications.
How is the silver contact attached to the terminal?
The silver contact is mechanically riveted to the stamped BeCu structure. In an in-die process, contact feeding, positioning, and riveting can be integrated with progressive stamping.
What packaging methods are implemented to prevent oxidation and transit damage for international shipments?
First, packed inside PET round cans. The filled cans are then placed into outer cartons, and the cartons are secured with strapping. After carton packing, goods are stacked onto pallets, wrapped fully with stretch film, and pallet strapping is applied for extra reinforcement. This multi-layer packaging protects parts against scratches, oxidation, and mechanical impact during long-distance overseas transport.
