What are EV Charger Riveted Contact Elements?
EV Charger Riveted Contact Elements serve as the critical current-carrying pathway inside high-voltage direct current charging pile contactors and DC fast-charging relays. Operating under high thermal stress and repeated mechanical closure, these components prevent arc erosion and minimize millivolt drop during 400A continuous charging cycles. Manufactured in our primary production facility as a custom OEM component, these riveted assemblies integrate cold-headed silver alloy tips with high-conductivity copper carriers. We supply global electrical equipment manufacturers with direct factory pricing, full lot traceability, and strict dimensional control for demanding automotive charging infrastructure.
Riveting Process Control for Copper Terminal Silver Plated for New Energy Switch
Solid vs. bimetal rivet selection criteria
We evaluate electrical load profiles to recommend solid silver tips for ultra-high current or bimetal rivet configurations to optimize precious metal cost efficiency.
Mechanical shear force testing protocols
Every production batch undergoes destructive push-out force testing to verify that the rivet stem and baseplate achieve minimum shear strength thresholds exceeding 180 MPa.
Precision stamping and alignment accuracy
High-speed progressive dies ensure the concentricity between the contact head and the mounting carrier stays within tight 0.02 mm alignment limits.
Surface oxidation protection and cleaning
Post-assembly ultrasonic degreasing and passivation treatments remove residual lubricants, guaranteeing pristine interface conditions for subsequent welding or bolting.
Typical Application Scope of Copper Terminal Ag-plated for HVDC Contactor
800V DC fast-charging pile main contactors
Designed specifically to handle the high transient inrush currents and DC breaking arcs inherent in modern ultra-fast electric vehicle supply equipment.
Commercial EV onboard charger switching relays
Compact contact elements engineered to fit strict spatial constraints while maintaining high dielectric strength and thermal dissipation capabilities.
DC energy storage system (ESS) safety disconnectors
Reliable switching performance for high-capacity battery rack protection switches operating under severe fault-current interruption scenarios.
