Abstract

The invention discloses an underground coal mine controllable electrical current fast connector. The fast connector comprises an explosion-proof female connector (1) and explosion-proof male connector (13), install O-ring in the blast female connector (3) install O-ring II (10) in the male connector proof, the proof female connector is connected to the U-shaped pin (4), U-type pin connected to the connector sleeve (5); proof male connector head connected with a U-shaped pin (12), U type pin is connected to the outer connecting sleeve (11); the connector sleeve is mounted O-ring III (9), and the inner sleeve and outer coupling sleeve connection plug-in connection . Beneficial effects: The device uses no bolts levels proof structure, to achieve electrical current off quickly controlled by a rotary connector snaps, conforms to the mine explosion-proof standards without fastening tools to help, you can achieve in a manual rapid explosion-proof electrical equipment docking operations.

Description

technical field [0001] The invention relates to an electrical joint used in coal mines, in particular to an underground coal mine controllable current on-off quick joint, which belongs to the field of quick joint devices. Background technique [0002] Cables in coal mines are power transmission devices for underground equipment. Under the control of strict coal mine explosion-proof requirements, how to realize the fast connection between cables is the key to reducing the labor intensity of workers and improving underground work efficiency. [0003] The quick connector is an accessory for connecting products, and the seamless connection between products can be realized by using the quick connector. Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water and oil, and semiconductor quick connect...
