Product Introduction
Products Description
The high voltage automotive fuses is a component of a fuse. It is mainly used in power distribution systems with a rated voltage of AC 500V and a rated current of 1600A as overload and short-circuit protection for lines and cables. This contact is usually electrically connected to the main circuit part of the fuse to ensure that the circuit can be quickly disconnected in the event of an overload or short circuit to protect the circuit safety.

production process
1. Punching: We have multiple punching machine production equipment, which are suitable for the production of various specifications of new energy fuse. These equipment have the characteristics of large production capacity and low power consumption, and the number of punching times per day can reach 2 million.
2. Pickling: Use acid solution to remove scale and rust on the surface of steel and clean the metal surface. Commonly used acid solutions include sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, etc., among which sulfuric acid and hydrochloric acid are the most commonly used.
3. Welding: Use automatic printing machines and automated welding equipment to weld the outer cap and the contact knife into components. The welding efficiency is high, the stability is good, the welding is seamless, and the appearance is beautiful.
4. Grinding: Use a grinder to treat the surface of the new energy fuse to improve the finish and precision of the product.
5. Riveting: Use an electric small punch for riveting, which has the characteristics of light size, high production efficiency, simple operation, low noise, high precision, etc., and is particularly suitable for factory buildings and workshops in high-rise buildings.
6. Sorting and packaging: The products are 100% visually inspected manually. After passing the inspection, they are packaged in vacuum packaging bags to effectively avoid surface scratches caused by collision and friction between products.
surface treatment
Silver plating
Silver plating is a surface treatment method with good decorative and anti-corrosion effects. The silver layer has high conductivity and reflectivity, and the silver layer can also provide good corrosion resistance. Due to the high price of silver, silver plating is usually used in occasions that require high decorative effects and high anti-corrosion requirements.
01
Nickel plating
The nickel plating layer has good chemical stability in the atmosphere and alkaline solutions, is not easy to change color, and will not be oxidized before 600°C. The nickel layer has high hardness, is easy to polish, has good wear resistance and corrosion resistance, but the disadvantage is that it is porous, which may affect
EV fuse protective performance.02
Galvanizing
The main purpose of galvanizing is to prevent corrosion. Its characteristics are low cost, easy processing and good effect. The galvanized layer is usually silver-white and can provide good corrosion resistance, but it is not suitable for friction parts because it may affect welding performance.
03
Tin plating
The tin plating layer has high chemical stability, is almost insoluble in dilute solutions of sulfuric acid, nitric acid and hydrochloric acid, and has good weldability. Tin plating can provide electrical conductivity and corrosion resistance, and tin is also often used to increase the solderability of EV Fuses.
