It is protected through the above technical solutions, film group interlayer can be formed monomer copper core, its surface is allowed not will receive damage
Wound.
The utility model is further arranged to: being coated with metal layer on the film separation layer.
Through the above technical solutions, metal layer has the effect effect of isolation and shielding, so that allowing it to be in conveying will not be by
To interference.
The utility model is further arranged to: frosted layer, and frosted layer and monomer are provided in the monomer copper core surface
Copper core is wholely set.
Through the above technical solutions, the setting of frosted layer can allow monomer copper core surface relatively rough, and then add subsequent
After work, the frictional force between other layers is bigger, improves the adhesive force of thin-film barrier layers and monomer copper core, allows monomer copper core
It is more stable inside cable.
In conclusion the utility model has the following beneficial effects:
(1) by using monomer copper core, inside solid, copper core section is the transmission of electricity section of cable, to allow cable
Inside is not in redundant space, so that the interior weight and consumptive material of the unit length of its power transmission line be allowed to be minimized；
(2) by using monomer copper core, since there is no the node mostly to interweave with copper wire, and node is harder, thus single
The cable that body copper core is produced is softer, more convenient to use.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
A kind of flexible fire-proof cable, as depicted in figs. 1 and 2, including for conductive major diameter monomer copper core 1 and according to
The secondary inorganic mineral insulation layer 2 being set in monomer copper core 1, metal fireproof layer 3 and outer insulation jacket 4.Using monomer copper core
1, inside solid, copper core section is the transmission of electricity section of cable, so that allowing inside cable is not in redundant space, to allow
The weight and consumptive material fallen in the unit length of its power transmission line are minimized.Meanwhile monomer copper core 1 does not need to interweave, and pass
The conductive core of system is formed by stranded copper wire is twisted, thus node that is more open, while being twisted inside this monomer copper wire
Harder, so that conductive core itself is harder after the completion of production, and it does not have twisted node using monomer copper core 1,
To the pliability that its pliability is copper core itself, so that not only section is small for the twisted battery core formed of opposite stranded copper wire, simultaneously
It is more soft.
Wherein, as depicted in figs. 1 and 2, inorganic mineral insulation layer 2 is constituted using mica tape, with good fire line
Can, improve the fire line of computer.In addition, being provided with protection insulating layer 5 between monomer copper core 1 and inorganic mineral insulation layer 2, allow
Inorganic mineral insulation layer 2 is isolated with monomer copper core 1.Wherein, protection insulating layer 5 includes the internal layer being bonded with monomer copper core 1
51 and the outer layer 52 that is set on internal layer 51, inorganic mineral insulation layer 2 be set on outer layer 52.Also, in internal layer 51 and outside
Allow it that can play fire-retardant effect when in use by the filling of fire retardant 53 filled with fire retardant 53 between layer 52,
After a few road fireprotection layers fail in front, it is delayed, to reach raising flameproof effect.In order to facilitate consolidating for fire retardant 53
It is fixed, it is arranged to helicitic texture between internal layer 51 and outer layer 52.
For the further protection to monomer copper core 1, as depicted in figs. 1 and 2, film is provided on 1 layer of monomer copper core
Separation layer, film group interlayer 6 can form monomer copper core 1 and protect, its surface is allowed to be not damaged.Meanwhile in order to improve
The composite effect of group interlayer is coated with metal layer 61 on film separation layer, and metal layer 61 has the effect effect of isolation and shielding, from
And it is allowed in conveying to be that will not be interfered.
In addition, actual in use, cable is relatively large in diameter, thus it is relatively difficult when pulling, in order to allow it to pull
It is more convenient, it is provided with several bulge loops 31 on metal fireproof layer 3, so that its External Insulation sheath 4 is squeezed, is formed
Certain rough structure, to make it more convenient when in use.Meanwhile during by cable bend, bulge loop
Side can be upheld, and side can collapse, therefore the setting of this bulge loop structure can also reduce half jin of bending, and bending is more
Add conveniently, reduces installation space.
During use, frosted layer 11,1 one of frosted layer 11 and monomer copper core are set on 1 surface of monomer copper core
Setting, that is, frosted layer 11 directly carries out frosted processing on 1 surface of monomer copper core or blasting treatment is formed.Frosted layer 11 is set
Setting can allow 1 surface of monomer copper core relatively rough, and then after following process, the frictional force between other layers is bigger,
The adhesive force for improving thin-film barrier layers 6 and monomer copper core 1, makes monomer copper core 1 more stable inside cable.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
