Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model relates to a novel fireproof cable, which comprises three wire cores 1, an insulating layer 2 is wrapped around each wire core 1 to prevent short circuit or electric leakage between the three wire cores 1, the three wire cores 1 are tightly adhered in three directions to reduce the diameter of the cable, an easy-to-break layer 3 is wrapped around the three wire cores 1, the easy-to-break layer 3 is made of several circles of wound tinfoil paper, the easy-to-break layer 3 is more easily broken after being locally extruded, a filler 4 is filled between the easy-to-break layer 3 and the three wire cores 1 to fix the position of the three cables, the filler 4 is made of foam, the filler 4 can be more easily peeled off, a fireproof layer 5 is wrapped around the tinfoil paper, a protective layer 6 is wrapped around the fireproof layer 5 to provide a good protection effect for the cable, the filler is wrapped by the easy-to-break layer 3, make this cable 3 of easy fault can the breaking occur when receiving local extrusion, can oppress the filling layer after 3 fracture of its easy fault, the filling layer receives local extrusion back deformation and breaks, take place its

protective layer

6 and 5 also can be more easily to shell after breaking when easy fault 3 and filling layer, make this fireproof cable can be more convenient shell its filling layer, easy fault 3, flame retardant coating 5 and protective layer 6, when having guaranteed that its cable possesses good fire proofness, make this cable more convenient when the wiring.

Furthermore, the fireproof layer 5 is formed by winding a plurality of circles of ceramic fiber paper, so that the fireproof performance of the fireproof cable is greatly increased.

Furthermore, the foam is hard foam, so that the foam can be easily broken when being locally extruded while providing certain support.

Further, the protective layer 6 is made of hard plastic, so that the protective layer 6 can provide a better protective effect.

Furthermore, the insulating layer 2 is made of soft plastic, so that the insulating layer 2 can be stripped more conveniently.

Furthermore, the material of sinle silk 1 is metal copper, makes this fireproof cable's sinle silk 1's resistance greatly reduced.

To sum up, when the novel fireproof cable is used, the electric connection end of the fireproof cable is firstly connected with electricity, before the electricity is connected, the insulating layer 2, the filling layer, the easy-to-break layer 3, the fireproof layer 5 and the protective layer 6 of the fireproof cable are required to be completely removed to the outflow cable core 1, and then the electricity can be normally connected, when the insulating layer 2, the filling layer, the easy-to-break layer 3, the fireproof layer 5 and the protective layer 6 of the fireproof cable are removed from the fireproof cable, the protective layer 6 of the fireproof cable is gradually and forcibly extruded by using special pliers, the fireproof layer 5 is extruded by the stress of the protective layer 6, the easy-to-break layer 3 is extruded by the stress of the fireproof layer 5, when the easy-to-break layer 3 is locally extruded by the fireproof layer 5, the easy-to-break layer 3 is continuously extruded by the stress to the filling layer, and because the filling layer is made of hard foam, the easy-to-break layer 3 is locally extruded by the easy-to, this fireproof cable's flame retardant coating 5 and protective layer 6 then can be appropriate hard with its pincers absolutely, and can not harm three sinle silks 1 of this fireproof cable inside, after flame retardant coating 5 all was pincers absolutely with regard to protective layer 6, peel off the protective layer 6, flame retardant coating 5, easy fault 3 and the filling layer successive layer that pinches absolutely, again slowly hard with power respectively pinches off behind its three insulating layer 2 at last, get rid of its insulating layer 2, can connect the electricity to sinle silks 1.
