With the rapid development of the economic society, the number of devices in large-scale electricity utilization centers such as markets, machine rooms and schools is increasing, and the task of reducing the energy consumption of the devices is urgent. In these electricity utilization places, there are a huge number of direct current electric equipment, and most of them use alternating current for power supply, and during operation, the alternating current needs to be converted into direct current through an alternating current adapter equipped for each equipment, and the conversion efficiency of the process is mostly only about 80%. Therefore, if direct current power supply can be directly adopted, the efficiency can be effectively improved, the energy can be saved, and the environment can be protected. Meanwhile, with the development of electric power systems, direct current power supply also plays an increasingly important role in the fields of smart power grids, smart homes and the like.

In a dc power supply system, a dc plug and a dc socket are very important as circuit connection devices essential for connecting a dc power supply to a dc power-consuming device. At present, the existing direct current plug and socket in the market are mostly low voltage and low current, and the direct current plug and socket for small electronic equipment can directly charge electronic products such as mobile phones and notebook computers.

When the plug is plugged in and pulled out of the direct current socket, because the current in the inductive load can not change suddenly, two ends of the load can induce a great reverse electromotive force to block the change of the load current, and the induced electromotive force is superposed with the input voltage to break down an air gap between the plug and the socket conductor to generate high-temperature electric arc. The high temperature that produces when the electric arc appears can ablate the plug and socket conductive parts, reduces the life of plug and socket. Meanwhile, the existence of the electric arc also easily causes personal electric shock accidents and even electrical fire, and brings great hidden danger to personal and property safety.
