Embodiment 1

[0032] As shown in the figure, an explosion-proof junction box of new materials with high safety performance is composed of a box body 1, a box cover and a threading opening. The inside of the box body is provided with a terminal row 4, and the four walls of the box body are provided with more than one Each threading port inside the box body is provided with a winding shaft 5, and the said winding shaft is connected with the screw port at the bottom of the box by the screw I6, and each threading port is provided with a cable sealing joint 9, and the cable The sealing joint includes a locking mechanism 11, a threading mechanism 12, and a fixing mechanism 13. The locking mechanism and the threading mechanism are locked and fixed through thread cooperation, and the threading structure is inserted into the fixing mechanism, and the fixing mechanism is fixed on the threading port;

[0033] The locking mechanism is a cylindrical structure, the locking mechanism is provided with a fir...

Embodiment 2

[0041] The explosion-proof junction box of a new material with high safety performance described in Embodiment 1 is different in that:

[0042] A protective layer is coated on the casing, and the composition of the protective layer is as follows in parts by weight:

[0043] 35 parts of epoxy resin, 0.5 parts of high alumina ceramic particles, 3 parts of methyl isobutyl ketone, 2 parts of polyacrylamide, 1 part of sodium pyrophosphate, 2 parts of diphenyl ethylene glycol, 0.1 part of acetone, polyoxypropylene glycerin 8 parts of ether, 4 parts of isophthalic acid, 15 parts of chlorinated paraffin, 1 part of titanium dioxide, 20 parts of n-butanol;

[0044] The preparation method of the protective layer is as follows: add the above-mentioned components into a ball mill, and after ball milling and stirring for 4 hours, transfer to a reaction kettle, stir for 1 hour at a temperature of 85° C., make it evenly mixed, and lower the temperature to 45° C. ℃, and maintained at this tem...

Abstract

The invention relates to an anti-explosion wiring box made of new materials with high safety performance. The wiring box is formed by a box body, a box cover and more than one wire threading opening. A wiring terminal row is arranged in the box body. More than one wire threading opening is arranged in four walls of the box body. A wire winding shaft is arranged at each wire threading opening in the box body. Each wire winding shaft penetrates through and is connected with a screw opening in the box body through a screw rod I. A cable sealing joint is arranged in each wire threading opening. Each cable sealing joint comprises a locking mechanism, a wiring mechanism and a fixing mechanism, wherein the locking mechanism is locked and fixed to the wiring mechanism through screw-thread fit, the wiring structure is fixed on the fixing mechanism in an inserted manner, and the fixing structure is fixed at the corresponding wire threading opening. The wiring box is characterized by simple structure, convenient to assemble and disassemble and good in sealing performance, so safety performance of the anti-explosion wiring box is improved.

Description

technical field [0001] The invention relates to a junction box, in particular to an explosion-proof junction box made of new materials with high safety performance. Background technique [0002] The explosion-proof type of electrical explosion-proof equipment currently used is mostly explosion-proof, that is, the components that can generate spark arcs when the electrical equipment is running are placed in the explosion-proof shell, and the explosion-proof shell bears the explosion pressure and can ensure that the internal flame gas spreads through the gap. Reduce the energy at the same time, prevent the detonation of external gas, the utilization rate of the explosion-proof junction box is high in the explosive place, the existing explosion-proof junction box is only equipped with terminals inside, and the length of the incoming and outgoing lines is relatively fixed, so it is often necessary to modify the electrical If the existing line length cannot meet the length requir...
