What is the role of the existence of fuse in headphone socket? For details, please see the introduction below.
The headphone socket controls the lights in the home. The most common ones in the family are one switch, one double control switch, two position switch, two position double control switch, three position switch, etc. All the line switches only run two lines inside: the front line and the zero line. 4 m? For cabinet air conditioner in family, 2.5 m? For others. I take three position switch and one double control switch for example, and so on. The safety wire is made of lead antimony alloy with high resistivity and low melting point. When the main circuit current is too large, the safety wire heats up quickly, and the temperature rises rapidly. When it reaches its melting point, the safety wire is fused, the main circuit becomes open circuit, and all electrical appliances on the branch circuit stop working. Therefore, under normal power supply, all electrical appliances in the home stop working together, which usually means the safety wire. Fuses.
In order to facilitate the use of electricity, some users of headphone socket privately change the safe wire into thick (large current allowed to pass) or flexible wire or copper wire, so that when using high-power electrical appliances, the safe wire will not break. However, the result of this approach is extremely risky, there have been such cases before; the current in the main road is so large that the front and zero line have become two fire Dragons It extends along each branch road, but the safety wire is safe without blocking the power supply.
