Description
Technical field
The utility model belongs to electric wire field, more particularly to a kind of heatproof wire.
Background technology
With the socio-economic development in China, the requirement to Electrical Safety also improves, has to use during electricity consumption therewith
To electric wire, emergency case, such as fire are run into, if electric wire catches fire at the same time, secondary disaster can be triggered, seriously jeopardize the peace of scene of fire
Entirely.Grant number CN206441564U discloses the fire-resistant wire that a kind of Novel anti-mouse ant baits, by outside wrapping flame-retardant layer and
Inside wrapping alkalescence brings realization fire prevention and protection against rodents, but flame-retardant layer can only realize that flame-retardant layer itself will not burn, and delay heat
Transmitting, heat can still be transferred to the alkaline layer or erosion resistant coating of inside, damage electric wire, and alkaline band is directly contacted with flame-retardant layer,
Perishable flame-retardant layer, causes electric wire damaged.
Utility model content
In order to solve deficiency of the prior art, the utility model provides a kind of heatproof wire.
The technical solution adopted in the utility model is：A kind of heatproof wire, including core, insulating layer, shielded layer, protection
Layer, flexible support layers, heat-insulated filled layer and flame-retardant layer, the insulating layer, shielded layer, protective layer successively from inside to outside wrapping described in
Core forms conducting wire, and multiple conducting wires are arranged inside the flexible support layers, and the heat-insulated filled layer is arranged at flexible support layers
Outside, the flame-retardant layer wrap heat-insulated filled layer.
Preferably, alkaline layer is equipped between the flame-retardant layer and heat-insulated filled layer, erosion resistant coating is equipped with inside and outside alkaline layer.
Further, the erosion resistant coating is carbon fiber belt.
Preferably, the section of the flexible support layers is triangular structure.
Further, flexible filling member is filled in the gap between the conducting wire and flexible support layers.
Further, the flame-retardant layer is uniformly distributed axially through equipped with wire, wire around flame-retardant layer axle center.
Compared with prior art, the beneficial effects of the utility model are：The heat transmitted by thermal insulation layer partition flame-retardant layer
Amount, prevents harness damage, and flexible support layers can improve the anti-pressure ability of electric wire, and triangular structure and flexible filling member make conducting wire more
Stablize；Alkaline layer can prevent destruction of the mouse ant to electric wire, and erosion resistant coating that is inside and outside while setting makes alkaline layer not corrode flame-retardant layer
With heat-insulated filled layer；The wire of flame-retardant layer can increase the intensity of electric wire, improve tensile capacity.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of heatproof wire, including core 1, insulating layer 2, shielded layer 3, protective layer 4, flexible support layers 5,
Heat-insulated filled layer 6 and flame-retardant layer 7, the insulating layer 2, shielded layer 3, protective layer 4 wrap the core 1 and form from inside to outside successively
Conducting wire, forms the structure of preliminary protection core；Multiple conducting wires are arranged inside the flexible support layers 5, and flexible support layers 5 are cut
Face is triangular structure, and flexible filling member 51 is filled in the gap between conducting wire and flexible support layers 5, improves the stabilization of electric wire
Property and anti-pressure ability；The heat-insulated filled layer 6 is arranged at outside flexible support layers 5, for separating the heat transfer of outside；It is described
Flame-retardant layer 7 wraps heat-insulated filled layer 6, and alkaline layer 8 is equipped between flame-retardant layer 7 and heat-insulated filled layer 6, is equipped with inside and outside alkaline layer 8
Erosion resistant coating 81, for preventing destruction of the mouse ant to electric wire, while alkaline layer 8 will not corrode flame-retardant layer 7 or heat-insulated filled layer 6；Resistance
Combustion layer 7 is uniformly distributed axially through equipped with wire 71, wire 71 around 7 axle center of flame-retardant layer, adds the intensity of electric wire,
Improve tensile capacity.
The operation principle of the utility model is：Protective layer 4, flexible support layers 5 and wire 71 inside electric wire improve
The stability of electric wire, compressive resistance and pulling force；When heated outside electric wire, heat resistant layer 7 can prevent electric wire from burning, and heat-insulated filled layer
6 can prevent the heat in the external world from reaching core 1, it is ensured that Electrical Safety.
The desirable embodiment according to the utility model is enlightenment above, complete by above-mentioned description, related personnel
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought.This item utility model
Technical scope be not limited to content on specification, it is necessary to determine the technical scope according to the scope of the claims.
