Problems solved by technology

The main wiring method used in the existing intrinsically safe boxes is the screw-pressed terminal. Because the space inside the intrinsically safe box is generally small, and miner’s lamps are generally used for lighting when installed underground, the lighting conditions are poor. Therefore, the existing The wiring of the intrinsically safe box is very inconvenient, the wiring speed is slow, and it is easy to make mistakes

Abstract

The invention relates to a mining intrinsic safety junction box capable of being quickly connected. The safety junction box comprises an upper cover assembly, a shell assembly and a rapid wiring terminal strip assembly, wherein the rapid wiring terminal strip assembly is installed in the shell assembly, and the upper cover covers the shell assembly to form a sealing cavity. The mining intrinsic safety junction box can be used for wiring of intrinsic safety circuits in the environment with dust and gas explosion risks in an underground coal mine, overcomes defects that a traditional intrinsic safety junction box is tedious in wiring and consumes time, and has advantages of being easy to operate and rapid in wiring.

Description

technical field [0001] The invention belongs to the technical field of mine junction boxes, in particular to a mine intrinsically safe junction box that can be quickly connected. Background technique [0002] The air in coal mines contains gas and coal dust, which can be ignited, burned or even exploded under certain conditions. Therefore, mine underground circuit systems have their special requirements. The junction boxes of mining circuit systems are generally divided into three categories: intrinsically safe junction boxes, flameproof junction boxes, and flameproof and intrinsically safe junction boxes. Intrinsically safe junction boxes are often used when the voltage is less than or equal to 60V DC and the current is less than or equal to 1A. Intrinsically safe junction box refers to a junction box that meets the intrinsically safe requirements of the circuit. Intrinsically safe type is an explosion-proof type of electrical equipment, which limits the energy of electri...
