Description

technical field

[0001] The invention relates to the technical field of cable accessories used in power cable engineering, in particular to a small explosion-proof connector used for power cable wiring. Background technique

[0002] When the production and storage areas of hazardous chemicals are out of control and leakage occurs, a large amount of flammable gas is dispersed in the air. If an electric spark is encountered, an explosion accident is likely to occur. Therefore, when the cable is disconnected, ordinary The connection method and insulation treatment must not produce sparks overflowing at the wiring, so as to achieve the purpose of preventing accidents.

[0003] In the coal mine, there is a lot of coal dust, and the dust is often reduced by water spraying. Therefore, the coal mine is often humid, and the wiring should be equipped with moisture-proof ability to prevent short circuit. When the water is not sprinkled in time, the coal dust exceeds the limit, and the ...
