What are the functions of the EV Relay Pure Iron Stamping Part?

The battery management system of new energy vehicles has extremely high requirements for safety and stability. As a core control component, the reliability of the EV Relay Pure Iron Stamping Part directly affects the accuracy of circuit switching. This type of precision hardware component, through structural optimization and material upgrades, provides stable support for the relay while meeting stringent requirements such as corrosion resistance and high precision, becoming a key component ensuring the safe operation of the battery system.

The main function of the Stamped Pure Iron Bracket for Contactor is to provide mechanical support and electrical isolation for the relay. It is fixed to the circuit board through riveting and welding processes, ensuring the relay maintains a stable position during frequent switching and preventing poor contact due to vibration or impact. The component uses electroplated nickel surface treatment to form a dense oxide layer, which can effectively resist corrosion caused by battery fluid leakage or environmental moisture, extending its service life. In addition, the reinforced bracket design increases structural strength, disperses the stress generated during relay operation, and reduces the risk of metal fatigue.

The main body is made of cold-rolled steel sheet, a material that combines high strength with excellent processing performance. Dimensional precision control down to 0.05mm can be achieved through stamping. The press-fit process utilizes the principle of metal deformation to firmly connect the High Precision Pure Iron Stamping for EV Parts to the substrate, reducing the heat-affected zone compared to traditional welding and preventing material performance degradation. The weld points are used to fix relay pins, ensuring electrical connection stability. Full-inspection PE bag packaging prevents scratches and oxidation during transportation, and the acid and alkali resistance of the electroplated nickel layer allows it to adapt to various harsh operating environments.

The Electric Vehicle Contactor Pure Iron Base is mainly used in circuit protection components such as relays, fuses, and fuse boxes in the battery management system of new energy vehicles. Its corrosion resistance allows it to maintain functional integrity even in scenarios where battery fluid leakage is possible, while high-precision dimensional control ensures accurate matching with relay pins, avoiding overheating caused by excessive contact resistance. Furthermore, the component design is compatible with multiple packaging forms and can be adapted to different relay models by adjusting the crimping position and welding parameters, reducing supply chain management costs for new energy vehicle manufacturers.

Compared to traditional brackets, the Electrical Pure Iron Stamping for EV DC Contactor achieves a weight of only 0.1kg through structural optimization, reducing the overall load on the battery pack. The thickness of the electroplated nickel layer is strictly controlled, and it can withstand 72 hours of salt spray testing without rust, far exceeding industry standards. In practical applications, the mating gap error with the relay is less than 0.02mm, ensuring stable contact within a temperature range of -40℃ to 85℃, effectively reducing safety hazards caused by circuit failures in new energy vehicles.

Our EV Relay Pure Iron Stamping Part is manufactured strictly according to the above technical standards, using high-quality pure iron raw materials and precision stamping processes, balancing high strength, high precision, and strong corrosion resistance. It can perfectly adapt to the installation requirements of various new energy vehicle relays, stably supporting the long-term, reliable operation of the circuit system.
