Embodiment 1

[0024] like Figure 1 to Figure 4 , an explosion-proof wiring device that is beneficial to ensure explosion-proof performance, including a groove-shaped base 1 and an upper cover 4 connected with the base 1 by bolts or screws, a wiring cavity 7 is formed between the base 1 and the upper cover 4, and the At least one threading tube 3 is also fixed on the side of the base 1, and the threading tube 3 includes a lead tube 32 fixed on the base 1, and the axis of the lead tube 32 is provided with a different-diameter through hole, and one end of the different-diameter through hole An internal thread is provided, and a sealing gasket 35 is embedded in the through hole of different diameter, and a compression nut 34 threadedly connected with it is arranged in the internal thread hole, and one end of the compression nut 34 and one end of the sealing gasket 35 contact, and the other end of the gasket 35 is fixed relative to the lead barrel 32, the gasket 35 and the compression nut 34 ar...

Embodiment 2

[0027] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 4 , because the base 1 and the upper cover 4 are mostly made of plastic materials in the prior art, no matter for safety considerations or material saving considerations. Failure, the base 1 is fixed with a plurality of threaded seats 8 for connecting the base 1 and the upper cover 4 with bolts or screws, and the threaded seats 8 are all internal threaded metal sleeves embedded in the base 1. In this embodiment The threaded seat 8 is a copper sleeve provided with an internal thread, and the fixed connection between the base 1 and the upper cover 4 is realized through the screw holes 9 provided on the upper cover 4 corresponding to the inner threaded seat 8 one-to-one.

Embodiment 3

[0029] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 4 , in order to ensure the sealing performance between the base 1 and the upper cover 4 , a sealing ring 2 is also provided between the connecting end faces of the base 1 and the upper cover 4 .

Abstract

The invention discloses an anti-explosion wiring device capable of guaranteeing explosion suppression performance. The anti-explosion wiring device capable of guaranteeing the explosion suppression performance comprises a base and an upper cover, a wiring cavity is formed between the base and the upper cover, at least one wiring conduit is further fixed on the side face of the base, each wiring conduit comprises a wire leading barrel, a reducing through hole is formed in the axis of each wire leading barrel, internal threads are arranged at one end of each reducing through hole, a sealing gasket is embedded in each reducing through hole, hold-down nuts in threaded connection with internal thread holes are arranged in the internal thread holes, external threads are also arranged on each wire leading barrel, locking bolts are arranged on the external threads, and the wire leading barrels are also provided with protrusions. The anti-explosion wiring device capable of guaranteeing the explosion suppression performance has the advantages that the structure is simple, the anti-explosion wiring device is suitable for anti-explosion connection of wire cables in a certain wire diameter range and has good sealing and explosion suppression performance, the connection speed of connector lugs of the wire cables is high, and connection stability of the connector lugs is good.

Description

technical field [0001] The invention relates to a protective device for electric wires and cables, in particular to an explosion-proof wiring device which is beneficial to ensure flameproof performance. Background technique [0002] The underground environment of coal mines is special, and there are flammable gases and dusts. Once the above-mentioned gases and dusts reach the explosion limit and encounter any electric sparks, it is very easy to cause serious production safety accidents. Therefore, all kinds of communication, monitoring, instrumentation and automation in mines It is particularly important for system equipment such as explosion-proof function. [0003] Underground coal mines have many lighting facilities and power equipment, and junction boxes are indispensable equipment in the process of zero-time long line and cable wiring. In the prior art, the seal at the joint between the junction box and the cables is prone to failure, and the cable joints in the juncti...
