With the needs of people’s daily life, the market has introduced active power sockets with fuses, but most of the active sockets are multi-purpose and porous, but the defect of this socket is that it cannot guarantee that the plug line of each socket can be used safely. The fuse is blown out. The power cord plug with fuse produced by Dongguan Junjian has a spare fuse added after improvement. If the fuse in normal use is blown, it can be replaced with a spare fuse immediately, so you won’t worry about finding the fuse temporarily.

A bad touch will only flash, and the voltage will not exceed 220 volts no matter how high it is. This is caused by excessive current or the diameter of the power cord is too small. The cause of excessive current is usually high-power heating appliances, such as rice cookers, electric stoves, and electric heaters.

If the power cord plug used is not the original factory configuration, the wire diameter is too small at the same time, or the overcurrent is too low when using the mobile socket, it will cause burning phenomenon or even fire. For example, the plug is inserted into the plug-in board and the contact area is small and only a little bit, and the excessive current required is the main reason that the plug is burned!

If it is determined that the triangular plug is burnt black, it is not recommended to continue to use it. Even if it can be used, it is best to replace it. At the same time, check whether the electrical appliances are faulty and the plugs are not damaged by ablation.

1. The electrical interface burning black is generally caused by arc ignition, and the incomplete contact area with the plug connection is too small, and the current is too concentrated during work.

2. The instantaneous high temperature of arc ignition leads to the formation of an oxide layer on the metal surface, which affects subsequent use. Prone to poor contact. Improper insertion will slowly heat up, and the heat will melt and burn black after the heat accumulates. Due to the high temperature, the internal deformation and contact conditions have further deteriorated, and continued use is likely to cause damage to the electrical appliances. How to prevent the plug from being burnt: Pay attention to the power of the electrical appliances when using the plug socket. Don't concentrate on using one socket. High-power electrical appliances are separated on different circuit sockets, and the load current is shared equally. The plug must match the socket. Do not mix different plug and socket types. The plug should be inserted firmly and as deep as possible to ensure good contact.
