What is the structure of Fuse?
Generally, a fuse is composed of three parts: one is the melted part, which is the core of the fuse, which cuts off the current when it is blown. The melt of the same type and specification of the fuse must have the same material, the same geometric size, and the resistance value. It should be as small as possible and consistent. The most important thing is to have the same fusing characteristics. Household fuses are usually made of lead-antimony alloys.
The second is the electrode part, usually two. It is an important part of the connection between the melt and the circuit. It must have good electrical conductivity, should not produce obvious installation contact resistance; third is the bracket part, the melt of the fuse is generally slender and soft, the function of the bracket is to fix the melt and make the three parts a rigid whole for easy installation and use, It must have good mechanical strength, insulation, heat resistance, and flame resistance, and should not be broken, deformed, burned, or short-circuited during use.
How can Thermal Fuses be classified?
The thermal fuse can be divided into:
According to the material: it can be divided into the metal shell, plastic shell, oxide film shell
According to temperature: it can be divided into 73 degrees 99 degrees 77 degrees 94 degrees 113 degrees 121 degrees 133 degrees 142 degrees 157 degrees 172 degrees 192 degrees...
