Copper Knife Blade For EV Fuse

As an important part of the electrical system of electric vehicles, new energy vehicle fuse copper contact caps are mainly used to connect fuses and circuit boards or other electronic components to ensure the normal operation and safety of the circuit system.

Good deformation resistance: The copper contact cap is not easily deformed under current load and can maintain stable shape and size, ensuring the reliability and stability of electrical connections.

Sustainable development: Copper is a recyclable green material that is conducive to saving resources and reducing environmental pollution. It is in line with the concept of sustainable development and contributes to the development of the environmental protection industry.

Strong fatigue resistance: Copper has excellent fatigue resistance and can withstand frequent current loads and mechanical vibrations, maintain long-term stable performance, and extend product service life.

Purchase copper materials: Purchase high-purity electrolytic copper or other suitable copper alloys from reliable suppliers to ensure that the materials meet relevant standards and requirements.

Design size cutting: According to the design size requirements, the original copper plate is cut into copper sheets of the required size. Cutting can be done by mechanical cutting, shearing or laser cutting to ensure precise dimensions.

Stamping: Using high-precision stamping equipment and molds, copper sheets are processed into predetermined shapes and sizes. The stamping process needs to ensure the appearance consistency and structural strength of the product.

Welding process: The processed copper sheets are connected together through welding technologies such as argon arc welding and laser welding to form a complete copper contact cap structure. The welding temperature and time are strictly controlled during the welding process to ensure that the welding joints are firm and reliable.

Cleaning and deoxidation: Clean the welded copper contact cap to remove dirt and oxide layer on the surface to ensure the surface is clean.

Appearance quality inspection: Check the appearance of the copper contact knife cap to ensure that there are no scratches, no defects, and a clean appearance.

Protective packaging: The copper contact knife caps that have passed the quality inspection are packed in shock-proof and moisture-proof packaging to ensure that they are not damaged during transportation and storage.
 

Improve corrosion resistance

• Prevent oxidation: Surface treatment technologies such as nickel plating, tin plating, etc. can form a dense protective film on the surface of the copper contact cap, effectively preventing oxidation and corrosion, thereby extending the service life of the product.
• Resistant to chemical corrosion: The treated copper contact cap can resist corrosion by chemicals such as acids and alkalis, and is suitable for various harsh working environments.

Enhance mechanical properties

• Improve hardness: For example, chrome plating can significantly improve the surface hardness of the copper contact cap and enhance its wear resistance.
• Wear resistance: The treated surface is more wear-resistant, which can effectively reduce friction loss and extend the service life of the product.

Improve electrical properties

• Reduce contact resistance: Treatments such as silver plating or gold plating can significantly reduce the contact resistance of the copper contact cap, improve its conductive performance and ensure stable current transmission.
• Improve conductivity: Specific surface treatments such as silver plating can improve the conductivity of the surface and ensure reliability in high current environments.

Improve appearance quality

• Smooth surface: Through polishing treatment, the surface of the copper contact cap is smoother and more beautiful, improving the visual quality of the product.
• Consistent appearance: Surface treatment makes the appearance color and gloss of each product consistent, improving the overall quality of the product.

Enhance product reliability

• Prevent micro-cracks: Surface treatment can fill in tiny surface cracks and defects and improve the overall structural strength of the product.
• Improve fatigue resistance: the treated surface is smoother, reducing stress concentration and enhancing fatigue resistance.
