Fixed Copper Terminal For New Energy High Voltage Relay
Products Description
The Fixed Copper Terminal for New Energy High Voltage Relay is specifically designed for high-voltage DC relays and charging pile contactors in new energy vehicles. As the core conductive and connecting component within the relay, this component solves the problems of heat generation and poor contact under high current transmission through precision riveting of stamped copper and silver contacts. It is a key node ensuring stable and efficient energy switching between the battery pack and the drive motor in the power system.
Product Details and Features
Integral Stamping of Substrate
No splicing or welding sections, ensuring uninterrupted current flow and avoiding the risks of overheating and breakage at welded areas. This is a standard Copper Stamping With Riveted Silver Contacts molding process.
01
Precision Riveting of Silver Contacts
A servo press controls the riveting force, ensuring seamless contact between the contacts and the copper substrate. This prevents detachment under vibration and eliminates localized contact issues and overheating.
02
Precisely Bending Lead-Out Arm
The bending angle and length are determined based on simulation data, matching the movement trajectory of the moving contact. There is no interference during the opening and closing process. This works in conjunction with the Electrical Contact Riveting Assembly to complete circuit connection and disconnection.
03
Uniform Plating with No Missing Plated Areas
After polishing and degreasing pretreatment, the electroplating operation applies a uniform coating thickness to the conductive areas and contact faces of the In-Die Riveted Moving Contact Assembly. The plated layer exhibits no edge peeling, blistering, or pinhole defects.
04
Material Performance and Advantages
The Precision Stamped Riveted Contact Assemblies use high-purity copper as the stamping raw material, with a conductivity of≥97% IACS. It possesses excellent thermal and electrical conductivity, quickly dissipating heat generated during current carrying and preventing localized heat buildup.
The contacts are made of a silver-based alloy material, exhibiting resistance to arc erosion and welding. In high-voltage DC high-current breaking scenarios, it can withstand thousands or even tens of thousands of breaking impacts.
As a core material in the Copper Carrier Riveted Silver Contact Assemblies, this product's material selection completely avoids harmful heavy metals, meeting the environmental protection requirements of the new energy industry. Furthermore, the material's high-temperature softening temperature is far higher than the upper limit of the conventional operating temperature of new energy systems, ensuring no degradation of mechanical properties during long-term operation.
Frequently Asked Questions
Why are silver contacts riveted onto the In-Die Riveted Moving Contact Assembly?
Copper is suitable as the main conductive structure, while silver contacts are suitable as the contact area. The combination of the two balances conductivity and contact performance.
Can this fixed copper terminal be used with our own high-voltage relay models?
We support custom development based on drawings. We can adjust the terminal bending and hole specifications according to the customer's relay plastic base and electromagnetic mechanism dimensions. It can match various HVDC contactor and EV charging relay structures, providing a Custom Copper Stamping for EV Relay customization service.
How should I choose between silver plating and tin plating?
For automotive passenger vehicles and high-power energy storage high-voltage circuits, silver plating is preferred, meeting the high conductivity and arc resistance requirements of the Riveted Contact Terminal Assembly. For outdoor DC charging piles and low-cost energy storage equipment, tin plating is an option, offering resistance to sulfide corrosion and controlling material costs.
