The base material of Fuse Contact T2Y2 Red Copper characteristics
National standard copper belt T2Y2 (Japanese standard copper model C1100) is also known as pure copper, copper purity ≥99.9%. The red copper of Fuse Terminal Contact has good thermal conductivity, processability, ductility, corrosion resistance and weather resistance. Copper Contact Terminal can be used in fuse link, capacitors, relays, contactors, circuit breakers and other electrical industries.
1. T2Y2 copper of the Fuse Terminal has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed.
2. The red copper of Fuse L-type Termial contains less impurities that reduce electrical and thermal conductivity. The electrical conductivity and thermal conductivity for red copper of Securing Lug (Fixing Slot) are second only to silver, and are widely used in the production of electrical and thermal conductivity equipment and chemical industries.
3. Red copper of Copper Securing Lug (Fixing Slot) has good weldability. Xiamen China Apollo selects high-quality T2Y2 copper to produce copper fuse terminals, which can be processed into various semi-finished products and finished products Fuse Contact by cold and thermoplastic processing.
The differences between electroplating matte (fog) tin and bright tin of Fuse Contact Cap
Matte tin plating Fuse Copper Contact Cap is a coating with good solderability and certain corrosiveness.Because of its easy welding and good conductivity, it is widely used in electrical and electronic parts Copper Outer Cap for Industrial Power Fuse and Copper Outer Cap for gG gL Fuse that need to be welded.
1. Matte tin plated Copper End Caps surface is dull and dull. Bright tin Copper Cap surface is bright and beautiful.
2. Matte tin plating crystals Outer Cap are coarser. Bright tin Outer Cap is added with brightening agent to make the crystals finer and shiny.
3. Matte tin Fuse End Plate welding is better. Bright tin Fuse End Plate solders poorly and tends to produce tin whiskers.
4. Fog tin Round Polished Copper end Cap has better high temperature resistance, less bright tin Fuse Copper end Cap, and is prone to the problem of secondary melting of tin.
5. The cost of fog tin Fuse Copper Cap Fitting is higher than that of bright tin Fuse Copper Cap Fitting.
6. Matte tin Fuse Metal End Cap is generally used for soldering terminals or SMT parts.Bright tin Fuse Metal End Cap is used in places with appearance requirements and cold-pressed connection terminals.
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.
