In the junction box, the insulators can be integrated into one, and an explosion-proof function is realized via matched wiring bolts; and the threaded structure is adopted in the wiring bucket, so that not only the explosion-proof function is realized, but also the cable wiring requirement can be met; the wiring bucket can be also used as a feeding bucket and has complete functions; the wiring bucket has the double explosion-proof and defensive line functions, and the favorable sealing to the junction box can be realized; and the novel explosion-proof main junction box can be used in two explosion-proof occasions like Exd I and Exd II, thereby having strong universality and being safer and more reliable.

Description

Flame-proof type main electrical scheme box is used in novel many places
Technical field
The utility model relates to the protector of a kind of electric wire, cable, relates in particular to a kind of novel many places and uses flame-proof type main electrical scheme box.
Background technology
Long cable section of ingoing line is the weakest flame proof link of flame-proof type terminal box, and what the long cable section of ingoing line of existing explosion-proof connection box adopted is the sealing ring sealing, if the outside diameter of cable and sealing ring mismate then can produce the gap, explosion-proof connection box loses the flame proof function; Even if sealing ring and cable adopt interference fit, but because sealing ring adopts is rubber, flame-proof type terminal box application places environment is abominable in addition, and sealing ring is aging accelerates the flame proof disabler of sealing ring.EU countries also recognizes the above-mentioned defective that the ring structure explosion-proof connection box exists, and adopt the composite anti-explosion structure one after another on explosion separation motor, but composite anti-explosion type motor can not be applied to ExdI(I class explosion-proof area), versatility is not high, and application places is limited.
The utility model content
The utility model provides a kind of novel many places safe and reliable, good airproof performance to use flame-proof type main electrical scheme box in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: flame-proof type main electrical scheme box is used in novel many places, comprise cassette holder and lid that removable seal connects, be provided with insulator in the cassette holder, be provided with two ends in the insulator and stretch out the inside and outside connection bolt of cassette holder, cassette holder one side is provided with line inlet port, and described cassette holder is provided with the wiring bucket with incoming line in the line inlet port outside, and the incoming line inner ring is provided with internal thread.
Described cassette holder is provided with dividing plate in the line inlet port outside, and dividing plate is provided with entrance hole, and wiring bucket one side is provided with feeding port, and feeding port is provided with cover plate outward.
The composition surface of described cassette holder and lid is a fixing structure, and the flame proof gap is not more than 0.1mm, and length of flame proof joint is not less than 25mm.
The composition surface of described cassette holder and wiring bucket, cassette holder and insulator is planar structure, and the flame proof gap is not more than 0.1mm, and length of flame proof joint is not less than 25mm.
The composition surface of described insulator and connection bolt is the periphery structure, and the flame proof gap is not more than 0.1mm, and length of flame proof joint is not less than 25mm.
The incoming line of described wiring bucket is bolted with sealing plug.
Adopt technique scheme, can reach following beneficial effect:
1, the incoming line of wiring bucket adopts helicitic texture, and the inlet wire cable adopts flame proof gland head inlet wire, and gland head and incoming line form threaded flameproof joint, and this constitutes flame proof defence line, first road.
2, cable passes entrance hole, the line inlet port on the dividing plate and after connection bolt is connected, opens the cover plate at feeding port place, fills from dried glue cable to be sealed in the wiring bucket, has formed flame proof defence line, second road.
3, said structure is adopted on the composition surface of cassette holder and lid, cassette holder and wiring bucket, cassette holder and insulator, insulator and connection bolt, can guarantee that the utility model is used for two kinds of flame proof occasions of ExdI, ExdII, and versatility is stronger, and application places is more wide in range.
4, manufacturer of the present utility model has prevented that with sealing plug shutoff incoming line foreign material from entering in wiring bucket even the terminal box, when needs insert cable, sealing plug is taken off use gland head shutoff incoming line.
Insulator of the present utility model can be unified into one, realizes the flame proof function by the coupling connection bolt, and the wiring bucket adopts helicitic texture, is to have realized that the flame proof function has satisfied the long cable section of ingoing line requirement again, and the wiring bucket is worked as powder funnel again, and function is complete; The wiring bucket has the function in dual flame proof defence line, realizes the terminal box good sealing property, and is more safe and reliable.
