Copper Blade For Electric Vehicle Fuse

Copper blade for electric vehicle fuse is a key electrical component, mainly used in the fuse system of electric vehicles. It is made of high-quality copper material with high conductivity and high corrosion resistance, ensuring that it can effectively conduct electricity and maintain stable performance when high current passes through. 

High conductivity: We choose excellent copper materials as the base material to ensure the efficiency and stability of equipment power transmission.

High strength and durability: After precision manufacturing and strict quality control, the copper contact knife has high mechanical strength and durability, and can withstand high current and frequent operations.

Safety: The design complies with the safety standards of new energy vehicles and can quickly fuse under abnormal circuit conditions to protect the safety of batteries and other electrical components.

• First, choose high-quality copper material, usually copper plate. The selected materials need to have high electrical conductivity and corrosion resistance to ensure the reliability and durability of the product in use.
• Cut the selected copper material according to the designed size. This process uses precision cutting equipment to ensure that the cut copper plates or bars are accurate in size, with smooth edges and no burrs.
• The cut copper plates or bars are fed into the stamping machine for shaping. The copper material is punched into the required contact blade shape through a precision stamping die. This process requires ensuring consistent dimensions and accurate shapes that meet design requirements.
• Use professional welding equipment and techniques to firmly weld the components together. The temperature and time need to be strictly controlled during the welding process to ensure that the solder joints are firm and defect-free.
• After stamping and welding are completed, oil and impurities will remain on the surface of the copper contact knife. Use special cleaning equipment and cleaning fluid to thoroughly clean the copper contact blade to remove all residues. After cleaning, dry it to ensure that the surface of the contact knife is clean and free of moisture.
• According to the design requirements of the product, the copper contact knife is surface treated. This may include electroplating, anti-corrosion coatings, etc.
• Each batch of copper contact knives produced must undergo strict quality inspection, and professional testing instruments and equipment are used to conduct a comprehensive inspection on each contact knife.
• Inspected copper contact knives will be packaged to prevent damage during transportation. Usually use anti-static plastic bags for inner packaging and sturdy cartons for outer packaging.

Inspecting the welding completion of copper blade for electric vehicle fuse is a key step to ensure its quality and reliability.
Visual inspection: preliminary judgment of welding quality.

• Weld size measurement: Ensure weld size meets design specifications.
• Penetrant testing (PT): detects surface and near-surface defects such as cracks and pores.
• Ultrasonic testing (UT): detects internal defects in welds, such as lack of fusion, slag inclusions, pores, etc.
• Strength test: Test the mechanical properties of the weld to ensure that it meets the design requirements.
• Macro and micro inspection: Analyze welding structure and micro defects through sectioning and microscopic observation.
• Electrical performance test: detect the electrical conductivity of the welding joint to ensure that its electrical performance meets the requirements.

1.Inner packaging: plastic bag
- Each copper contact blade is individually placed in an anti-static plastic bag to prevent friction and damage during transportation.
- The plastic bag should be well sealed to ensure that the copper contact blade is not affected by moisture or dust.

2.Outer packaging: carton
- Neatly arrange the plastic bags containing the copper contact blades inside a sturdy corrugated box.
- Add filling materials such as foam and bubble pad to the carton to reduce possible vibration and impact during transportation.
- There should be clear product labels and handling signs on the outside of the carton, such as "Fragile", "Keep Dry", "Handle with Care", etc.
