[0002] Industrial connectors are mainly used for connecting the circuits between various industrial equipment, so as to realize the electrical connection between various industrial equipment. Industrial connectors are divided into male heads and female heads, and are mainly applied to the power supply of high-power, whole-cabinet servers. When industrial equipment needs to be connected, the male industrial connector and the female industrial connector must be connected by plugging.

[0003] For ordinary industrial connectors, the plugging connection is relatively convenient. The flip cover of the female industrial connector is opened, and the plug core of the male industrial connector is aligned with the plug sleeve of the female industrial connector for connection.
