Product Introduction
Fuse end cap and contact are key conductive and structural components in new energy power protection systems, widely used in high-voltage protection scenarios such as electric vehicle (EV) fuses, photovoltaic (PV) fuses, energy storage system fuses, PDU (power battery unit) fuses, UPS DC links, NH fuses, BS fuses, and fast fuses. This component undertakes three core functions: current transmission, arc isolation, and mechanical support. Its material selection, surface treatment, and welding quality directly determine the rated current carrying capacity, breaking capacity, and long-term reliability of the fuse.
Design advantages
Adaptive structural design
The Fuse end cap and contact adopt a cylindrical structure, which can be accurately matched with standard fuse ceramic tubes. Combined with reinforced sealing technology, it can effectively isolate pollutants such as moisture and dust, prevent electrolyte leakage or external corrosion from affecting the internal components of the fuse, and improve the service life of the product. This optimized structural design also maintains stable tightness in high-temperature working environments.
Optimization of high current transmission
By optimizing the Fuse contact knife cap structure, the current contact area is expanded, the contact resistance is reduced, and it can withstand the instantaneous high current surge of EV 800V high-voltage platform, ensuring that the fuse can quickly disconnect the circuit and protect the precision components in the later stage when a short circuit fault occurs. It greatly enhances overall power supply safety.
Anti vibration and anti loosening design
The connection between the contact and the cap is designed with a dual design of welding and structural locking to avoid contact loosening caused by high-frequency vibration of the vehicle or equipment operation vibration, ensuring the continuity and stability of current transmission. The Outer cap and contact are suitable for dynamic working conditions such as new energy vehicles and industrial mobile equipment.
Engineering Applications and Scenarios
New energy vehicles
Welding joints for fuses are used to adapt power battery pack fuses, PDU distribution unit fuses, and DC fast charging port fuses, solving the problems of high current transmission and short circuit protection on 800V high-voltage platforms, and ensuring the safe operation of vehicle high-voltage systems.
Photovoltaics and energy storage
End cap and terminal are compatible with photovoltaic inverter fuses, energy storage system DC link fuses, and UPS power supply fuses to withstand the frequent charging and discharging current impact of energy storage systems, improving system reliability and safety.
Industrial power distribution
It is suitable for standard specifications such as NH fuses, BS fuses, and quick fuses, used for circuit protection of industrial distribution cabinets and automation control equipment, providing stable electrical connections and fault protection for industrial equipment.
Other scenarios
