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 TV was often damaged by fuses.
At that time, the fuse was a regular glass tube fuse, 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), and it 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.
