Fuse: Fuse is also called current fuse. Tan C 127 defines it as "fuse".
When the circuit fails or is abnormal, the current is constantly rising and rising.
? Large current may damage some important or valuable devices in the circuit, burn out the circuit or even cause a fire. If the fuse is properly placed in the circuit, when the current abnormally rises to a certain height and generates heat, the fuse will fuse itself to cut off the current, thus protecting the safe operation of the circuit.
1, filiform. Early primitive fuses were directly locked with screws and used for old-fashioned switches and sockets of various sizes.
2. sheets (naked sheets). It is more convenient to use than the previous filiform.
3. Glass tube. There are several different sizes, which are common in electronic products.
4, ceramic tubular. There are several different shapes and sizes to avoid glass bursting.
5, plastic sheet with metal pin: car fuse.
6.SMD type
7, cylindrical, plug-in: directly welded on the circuit board, used in products.
Logo:
Most fuses are marked on the body or end cover to indicate their rating. However, "chip" fuze has little or no function, so it is very difficult to identify it.
Fuze marking usually conveys the following information:
1, rated ampere fuse
2. Voltage level of fuse
3. Time-current characteristic, namely speed fuse.
Function:
The fuse invented by Edison 100 years ago was used to protect the expensive incandescent lamp at that time. With the development of the times, fuses protect electronic/power equipment from current/overheating damage and avoid serious damage caused by internal faults of electronic equipment.
