What is the Riveted Contact Copper Stamping Assembly?
Riveted Contact Copper Stamping Assembly is designed for relay contacts, low-voltage switching components, smart-home control modules, automotive electrical systems, and industrial control equipment where a stamped copper current path and a mechanically fixed silver contact are required in one component. The assembly can use copper stamping with AgSnO2 or AgNi contact material according to the electrical load and approved design. Production covers stamping, contact riveting, dimensional inspection, and batch quality control, with OEM and customized manufacturing based on drawings, samples, or technical specifications.
Material & Performance Features of Silver Contact Riveted Copper Stamping Parts
Low Electrical Resistance Design
Minimizing millivolt drop across the connection interface is critical for preventing localized overheating. Our stamping process ensures intimate surface contact between the rivet shoulder and the copper substrate. This physical configuration maintains a stable electrical pathway during continuous current flow.
Superior Cold Heading Bond Integrity
The mechanical riveting interface relies on precision tonnage control during cold forming. By locking the silver alloy head into the pre‑pierced copper stamping, we achieve high push‑out resistance. This mechanical interlock prevents tip detachment during repetitive thermal expansion cycles.
Optimized Thermal Dissipation
High‑purity C1100 copper carriers exhibit exceptional thermal conductivity, rapidly transferring Joule heat away from the contact zone. This thermal management capability protects surrounding thermoplastic relay housings from premature degradation under sustained loads.
Burr‑Free Precision Stamping
Advanced progressive die tooling eliminates micro‑burrs along sheared edges. Clean, uniform edges prevent micro‑arcing phenomena in tight clearance enclosures, ensuring long‑term operational stability within compact switching devices.
Copper Stamping and Riveting Assemblies for Copper Contact Element
Precision Stamped Carriers
Copper carriers are manufactured using progressive die or precision stamping processes, depending on the part's structure. Features such as holes, slots, bends, mounting areas, and positioning structures can be integrated into a single stamped profile.
Riveted Contact Assemblies
Silver contacts are mechanically secured to the copper stamped parts via a controlled riveting process. Riveting parameters must be strictly maintained to ensure the assembly meets specifications while preventing damage to the contact surface or deformation of the copper component.
Dimensional Control
Critical dimensions are controlled in accordance with approved drawings, focusing on contact position, stamped profile, mounting hole location, bend dimensions, and overall assembly height. Specific inspection methods are determined based on dimensional tolerances and production volume.
Production Process Control
The typical production workflow is: material inspection → stamping → contact feeding → riveting → dimensional inspection → visual inspection → packaging. Process inspection points are established for parameters such as contact position, riveting formation, stamping deformation, burrs, and final assembly dimensions.
