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.
What’s the principles and advantages of resistance brazing for Fuse Contact Cap ?
Brazing End Cap and Contact is a connection method that keeps the temperature between the melting point of the solder and the melting point of the base material, fills the gap between the base material and the base material by melting the solder, and solidifies and crystallizes to achieve interatomic bonding. Resistance brazing of End Cap and Contact Welding Components is a welding method in which two workpieces Fuse End Cap and Terminal are placed between two electrodes of Design of Welded Joints and pressed together and energized, so that current flows through the workpiece of Fuse Outer Cap and Contact, and the workpiece Fuse Cap and Contact itself generates resistance heat to heat the workpiece and melt the solder.
Resistance brazing features:
1. Fast heating speed
Direct heating through the current, second-level speed.
2. Good welding effect
The brazed joint is smooth, beautiful and firm.
3. Small deformation
The heating concentration is uniform, so the heat affected zone is small, and the deformation and stress are also small. It is easy to ensure the dimensional accuracy of the workpiece, and it is not necessary to consider the correction or heat treatment process after welding.
4. High thermal efficiency
Using the internal resistance heat source of the workpiece itself, the heat energy loss is relatively small, the thermal efficiency is relatively high, and the energy saving is saved.
5. The heating temperature is low, which has little influence on the structure and performance of the workpiece base metal.
6. Simple operation
One-button operation requires less proficiency of workers and low labor intensity.
7. The temperature is easy to control
Precise welding current can be set for easy heating and cooling.
8. Most of the brazing thick copper plates, copper bars and copper bars can also realize the connection of dissimilar metals.
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.
