Products Description
In relays, contactors, circuit breakers, battery management systems (BMS), charging equipment, power switching devices, and energy storage systems, the In-Die Riveted Moving Contact Assembly directly determines the conduction performance, temperature rise control capability, mechanical life, and electrical life of the switching system.
For new energy, high-voltage DC switching, and frequent switching scenarios, the in-mold riveting structure of the Riveted Contact Terminal Assembly provides stable engineering solutions in terms of contact resistance control, welding alternatives, automated assembly compatibility, and long-term reliability.
Material Selection
| Copper Carrier | High-purity copper (Cu≥99.9%) is used, possessing excellent conductivity (≥58 MS/m) and mechanical strength to ensure efficient current transmission and structural stability of the Electrical Contact Assembly. |
| Silver Contacts | AgSnO₂ alloy (silver content≥99.5%) is selected, and a microcrystalline structure is formed through cold forging, improving the contact's resistance to arc erosion and extending the service life of the Silver Contact Riveted Copper Assemblies. |
Technical Compatibility
Material Selection Logic
Silver Contact Rivets Copper Assemblies use T2 copper as the base, leveraging copper's high conductivity and resistance to repeated bending to meet the frequent switching conditions of the moving contacts. The silver alloy on the contact surface is selected according to the equipment's rated current, voltage, and arc loss conditions.
In-Mold Riveting Process
Electrical Contact Rivets Assemblies adopt an in-mold integrated riveting process, directly riveting the silver contacts during continuous stamping, eliminating secondary assembly. Product thickness, coaxiality, and riveting strength are uniformly controlled by the mold, adapting to automated high-speed assembly lines.
Full Specification Customization
Silver Alloy Contact Riveting Parts can be fully customized according to customer CAD/3D drawings. The copper sheet shape, number of contacts, and riveting height are flexibly adjustable, with rated current from 0.5A to 250A, suitable for four types of products: automotive relays, photovoltaic accessories, low-voltage circuit breakers, and charging pile switches.
Frequently Asked Questions
Do you support custom designs based on provided drawings?
Yes. After the customer provides drawings in PDF/CAD/3D format, our engineering team will complete a process feasibility assessment (DFM) and quotation for Precision Stamped Riveted Contact Assemblies within 48 hours.
