I still remember when I was studying electronics and electrical appliances, and every semester when I came home from vacation, I was called by my neighbors to repair the TV. At that time, I used black and white TV sets, and the voltage was also unstable. The most damaged TV set was the fuse.
At that time, Shenzhen fuses were ordinary glass tube fuses, and it was not very convenient to buy a fuse in rural areas. Sometimes, iron sheets or wires were used to directly connect the circuit as a fuse (I believe many people have done this before), which could still be used normally. However, this use was very unsafe, and sometimes it could damage other parts of the TV. Since then, I have been deeply impressed by this type of transparent glass tube fuse.
Fuses, also known as fuses, are defined as "fuse links" in international standards. They are electrical components installed in a circuit to ensure safe operation of the circuit.
Electronic products are all-encompassing, and these products that require electricity must be equipped with small components that shoulder the same responsibility for safety. Fuses are not only available in 3C products, but also in regular cars or electric vehicles.
Nowadays, as products become smaller and more integrated, the shape and size of fuses are also greatly different from traditional fuses. For example, the fuses of mobile phones must comply with the trend of fast charging, withstand instantaneous large currents, and achieve their protective function. The requirements for fuses are becoming higher and higher.
The glass tube fuse fuse wire we usually see is not a single material. It is an alloy made of lead, antimony, and tin, which is added to achieve low melting point. Both ends are copper caps, which will have better conductivity. The surface of the copper cap is treated with nickel plating
The appearance of a fuse has the earliest use of a strip shaped fuse, which is directly fixed at both ends with screws and used on old-fashioned switches
Sheet shaped fuses are composed of plastic sheets and two metal sheets, commonly used in automobiles, and glass tube shaped fuses are commonly used in electronic products
A cylindrical fuse directly solders the pins at both ends onto the circuit board, while a square fuse has insulation and space saving characteristics, and is commonly used in electronic products such as computers.
The function of a fuse is to continuously increase the current when a circuit malfunctions or malfunctions, and the increased current may damage components, burn out the circuit, or even cause a fire.
