1. Organic thermal body type:
It is the use of organic material has a fixed melting point and manufactured to adapt to different temperature fuse. This type of product is small in size, such as a resistor, with leads at both ends, which can be used alone or connected with wires through wiring terminals. If sealing is required, chlorinated polyvinyl chloride pipe can also be used for sealing. Its structure and working principle is that when the organic temperature sensing body melts, the metal conductive sheet connected with the shell is pushed away by the thrust spring, so that the original conductive sheet in contact with the lead front-end contact is no longer in contact with it, in the disconnected state. The lead and the lead are cut off, no current through, the power supply is cut off.
2. Metal fuse wire type:
It uses the alloy wire with different melting point as a temperature sensitive body. When the external temperature reaches the melting point of the alloy wire, the alloy wire melts to achieve the purpose of cutting off the circuit.
This kind of factory "product volume size and organic temperature body similar, both ends also have leads, components can be used alone, can also be connected with wire terminals. Can also be protective sealing. Its structure and working principle can be found on our website
3. Alloy welded reed type:
It is an element that uses alloy solder with different melting points to press together two tongue-shaped reeds. Its structure and action principle are. When the external temperature reaches the melting point of the alloy solder, the alloy solder will melt rapidly and the compressed spring sheet will spring back to its original position. At this point, the wire is disconnected, so that the original circuit through the spring sheet, alloy solder and fixed reed is cut off.
The main r & D personnel of the company's products are senior engineers in the domestic thermal protector industry, and have received advanced training from foreign authoritative manufacturers of temperature protector. The product quality and technical level are in a leading position in the industry. The company adopts European and American management mode, employs foreign managers and goes abroad for further study.
Our products are sold all over the world, widely used in all kinds of rechargeable battery packs, household appliances, motors, transformers, lighting fixtures, power tools, electric heating electric and so on over current, over temperature safety protection. All products have passed China (CQC), The United States (UL), Germany (TUV), South Korea (KC) and other safety specifications certification, products have passed environmental ROHS,REACH testing and obtained certificates.
The company adhere to the "pursuit of zero defect from various aspects, do absolutely meet customer demand", to be safe and reliable intelligent win min function device Portland as a corporate mission, with "customer satisfaction is our pursuit" as the demand for raw materials, production process of each step are strictly monitored, do a good job in every product.
Our corporate culture: to build thermal protector aircraft carrier, striving for a good Brand in China; To provide customers with overheat and overflow comprehensive solutions, to create wealth for employees, to create value for the society; Customer satisfaction, employee satisfaction, social satisfaction; Customer - centered, quality of survival, efficient development.
