The junction box of switching, junction box exposes in the seawater, and junction box can bear certain seawater pressure.To ensure to connect
The sealing of line case mainly uses individual layer sealing ring form between housing and lid, packer form between cable and housing,
This seal form can make junction box be in sealing state, it is adaptable to deep water working environment.But this mode structure letter
It is single, although sealing effectiveness can be reached, but it is very high for the wiring technique requirement of staff's cable, it is necessary to by cable
It is cumbersome in junction box's back panel wiring through after stuffing-box, and element inside butted line case causes certain infringement,
Junction box easily by seawater corrosion, shortens the service life of junction box, so as to cause serious influence.
The content of the invention
It is an object of the invention to provide a kind of simple structure, simple to operate, good airproof performance, compressive property be good, production efficiency
The special explosion-proof wiring box of extra large cable high.
The technical scheme is that：A kind of special explosion-proof wiring box of extra large cable, including casing, case lid, composite bus bar, institute
State box house and be installed with composite bus bar, be fixed on the inside of casing, casing on the composite bus bar by insulator
Both sides be provided with several watertight binding posts, be provided with conducting element in the watertight binding post, the conducting element is inserted
Enter and be fixedly connected in composite bus bar, sealing ring, the space between the casing and case lid are provided between the casing and case lid
Filled with filler, the top of the casing is provided with pressure relief device and pressure sensor, is provided with the top of the pressure relief device
Solenoid valve cover, the bottom of the pressure relief device is provided with pressure compensator, and the pressure compensator is arranged on the inside of casing.
Further, the watertight binding post is provided with sealing plate with the extraneous interface being connected, and the sealing plate is arranged on water
In the groove of contiguity line terminals front end.
Further, the casing is gorge ellipse shape long, and the surrounding bottom of the casing is provided with four bases.
Further, described filler thing is gum filler.
Further, the casing and case lid are low magnetic stainless steel material, and the outer layer of the casing has platinum/titanium metal thin film.
The present invention has the advantages and positive effects that：Because the both sides for using above-mentioned technical proposal, junction box set some
Individual binding post, in limited space, can connect multiple cables, save space；The pressure being provided with outside junction box
Sensor and pressure relief device ensure that experience extraneous hydraulic pressure it is excessive when, solenoid valve cover will release partial pressure, and press
The pressure balance of force compensating device guard box inside and outside, it is to avoid because excessive pressure causes the damage of junction box and blast, make
Use and more facilitate；With simple structure, the advantages of sealing, compressive property are good, production efficiency is high.
