Abstract
The invention discloses a flame retardant distribution box. A thermal insulation layer and a flame retardant layer are arranged inside an outer shell, so that when fire occurs on the distribution box, flames are prevented from further spreading, meanwhile, the distribution box and an external circuit are connected through a made-to-order contact made of flame retardant materials, and the possibility that the flames continue to spread from the inside of the distribution box via the circuit is eliminated. The flame retardant distribution box is simple in structure and manufacturing process, and suitable for large-scale production, and has good social benefits.

Summary of the invention
The objective of the invention is to: a kind of technical scheme that can overcome the above problems is provided.
The present invention realizes in the following way:
A kind of fire-retardant distribution box, comprise shell, described fire-retardant distribution box also comprises thermal insulation layer, flame-retardant layer, fire-retardant joint, described thermal insulation layer and flame-retardant layer are attached on the shell of distribution box from outside to inside successively, described shell is provided with fire-retardant joint, described fire-retardant joint is made by fire proofing and is run through thermal insulation layer, flame-retardant layer, is provided with electric conductor in the middle of fire-retardant joint, connects the inside and outside lead of distribution box.
As further innovation of the present invention, the stage casing of the electric conductor of described fire-retardant joint is the fuse-link that fusible material is made, and also is provided with cavity in the position of the fire proofing inside of fire-retardant knot joint fuse-link.
As further innovation of the present invention, described fuse-link is galvanized wire.
As further innovation of the present invention, described fire proofing is pottery.
As further innovation of the present invention, described flame-retardant layer adopts cement to make.
As further innovation of the present invention, described thermal insulation layer adopts asbestos to make.
As further innovation of the present invention, also be provided with extinguishing device in the described distribution box, described extinguishing device comprises thermoinduction module, electromagnetically operated valve, fire extinguishing spray jar, and described thermoinduction module is connected with electromagnetically operated valve, and described electromagnetically operated valve is arranged on the tank body oral area of fire extinguishing spray jar.
As further innovation of the present invention, also comprise the heat conduction coil that is laid on distribution box flame-retardant layer surface in the described distribution box, the two ends of described heat conduction coil are connected with the thermoinduction module.
Beneficial effect:
1. the present invention is by arranging thermal insulation layer and flame-retardant layer in shell body, when preventing the distribution box breaking out of fire, further stretching of flame, the special fit of making by a fire proofing that is connected of distribution box and external circuitry connects among the present invention simultaneously, eliminated flame in the distribution box via circuit continue to stretch may, simple structure of the present invention, manufacture craft are also fairly simple, are fit to large-scale production and have good social benefit.
2. fire-retardant joint of the present invention inside also is provided with a fuse-link, after fire takes place, disconnects the circuit that is connected with distribution box because can melt voluntarily by thermal fuse-link, prevents because the electric deterioration that causes the intensity of a fire of dew has further improved fail safe.
3. the used material of the present invention is drawn materials all simpler and easyly, and cost of manufacture is low, is fit to large-scale production.
4. inside of the present invention also is provided with an automatic extinguishing device, can make distribution box when internal fires, carries out preliminary fire extinguishing, prevents the expansion of the intensity of a fire, has further improved fail safe.
