Background

At present, most of high-power connectors applied in the communication industry adopt a low-voltage and high-current transmission mode; the transmission mode of the large current can cause the temperature to be greatly increased, and hidden troubles are brought to an electrical system. Therefore, the high-voltage connector is used. In the product plugging and unplugging process, a large voltage difference exists between the male and female end contact pieces, so that air between the male and female end contact pieces is ionized, current is formed and flows through an air gap, and electric arcs are generated. The arc not only aggravates the damage of the short-circuit fault of the power system, but also creates the danger of fire and even explosion. Therefore, the connector needs to have an arc extinguishing function, and usually, an arc extinguishing connector adopts a mode of a built-in magnet and generating an external magnetic field, so that an arc is deviated, the extinguishing of the arc is accelerated, and the risk of the arc is avoided. However, the current arc extinguishing connector has the following defects: two or more magnets are arranged in the magnetic bearing, so that the magnetic bearing has low assembly efficiency and large product volume due to the requirement on the installation polarity.
