A DC plug and socket with strong arc extinguishing capability and its operation method

Abstract

The invention discloses a DC plug and a socket with strong arc extinguishing capability and an operation method. The DC plug comprises pins, a plug shell, an arc extinguishing chamber and a pressing sliding block. The arc extinguishing chamber is internally provided with arc extinguishing contacts and an arc extinguishing grid piece, a permanent magnet and a pull rod, and the arc-extinguishing contacts are respectively connected with two poles of the pins. The pull rod and the pressing sliding block are connected by a guide rod. The DC socket comprises jacks and a socket shell. The pressing sliding block and the socket shell are respectively provided with a connection buckle and a connecting groove. A connection function and an arc extinguishing function of the DC plug and socket are separately arranged. The pressing sliding block controls connection and disconnection of the arc-extinguishing contact, so as to control closing and opening of an internal circuit of the DC plug and socket, and DC arc generated in working goes out in the arc extinguishing chamber. The DC plug and socket have strong arc extinguishing capability, and prevent phenomenon of arc caused by plugging the DC plug and the DC socket under a charged state, and can be safely and reliably applied to work scenarios of DC heavy load.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to a DC plug and socket with strong arc extinguishing capability and an operation method. Background technique [0002] With the rapid development of the economy and society, the equipment in shopping malls, computer rooms, schools and other large power consumption centers continues to increase, and the task of reducing the energy consumption of these equipment has become very urgent. There are a huge number of DC power equipment in these power places, and most of them use AC power supply. When working, it is necessary to convert AC power into DC power supply equipment through the AC adapter equipped with each device. The conversion efficiency of this process Most of them are only about 80%. Therefore, if DC power supply can be directly used, it will effectively improve efficiency, save energy, and protect the environment. At the same time, with the development of p...
