Material properties of Fuse End Caps Brass material
The performance of H65 Brass Inner Cap is between H68 and H62, the price is cheaper than H68, and it also has higher strength and plasticity, Brass Inner End Cap can well withstand cold and hot pressure processing, and has a tendency to corrosion cracking.Mainly used in the production of EV Fuse Brass Inner Outer Cap,PV Fuse Outer Brass Cap, Nickel Plated Brass End Caps,mainly used as electrical, thermal, corrosion-resistant equipment.
1.Brass of Fuse Inner Cap has very good plasticity and high strength, good machinability, easy welding, and general corrosion stability.
2.Brass of Brass End Cap has high strength and plasticity, can well withstand cold and hot pressure processing, and has a tendency to corrosion cracking.
3.H65 brass of Fuse End Caps has good mechanical properties and wear resistance, and can be used to manufacture precision instruments and Fuse Contact parts.
Application of new energy vehicle fuse
EV electric vehicle fuse: The EV fuse with End Cap and Contact used in electric vehicles not only needs the fuse protection performance of DC high-voltage fuses in ordinary power distribution systems, but also needs to withstand the shock and vibration of road vehicles. A unique class of requirements for the Contact Knife Cap Fuse used.At present, the working voltage of passenger cars is generally above 370V, and that of buses is above 576V, which is much higher than the 12V/24V of traditional automotive electrical components. Such a high working platform voltage requires End Cap Terminal EV/HEV fuses to have both the high breaking capacity of low-voltage fuses and the high reliability of automotive fuses with Outer Cap Contact.In addition to the power battery main fuse, there are also automotive air conditioning systems, heating systems, and DC/DC systems (converting the power battery voltage to 14 V to provide the vehicle Low-voltage power supply, similar to generator) and other accessory high-voltage circuits, each circuit needs to be connected in series with a DC high-voltage Copper Cap Contact Fuse for circuit protection.
In the high-voltage distribution box of an electric vehicle, the output terminal is mainly connected to the auxiliary power supply system of the vehicle, and the inside of the distribution box generally includes an electric heating fan branch, an air-conditioning compressor branch, a DC/DC branch and a charger branch. These four branches, each branch needs to install line protection Knife Contact Fuse, the purpose is to cut off the power protection circuit in time when each load is short-circuited, and avoid vehicle fire. With the comprehensive advantages of small size, good shock resistance and low price, fuses have been widely recognized and used in large quantities, and have become the main components Fuse Terminal recognized at home and abroad as the short-circuit protection of electric vehicles.
For the Copper Contact Cap fuse standard system, it is mainly divided into IEC standard, UL standard and ISO standard. Among them, Chinese GB, German DIN and British BS basically adopt IEC standard. IEC standards mainly include IEC 60127, IEC 60269, etc. UL mainly includes UL248, etc. ISO mainly includes ISO 8820 series.
