Excellent fire resistance is also equipped with, is current those skilled in the art's urgent problem to be solved.
The content of the invention
In order to solve the above problems, the utility model provides a kind of cable resistant to bending.
A kind of cable resistant to bending of the utility model, including cable core, the outside of the cable core are arranged and led to successively from the inside to the outside
Cross binding agent and be bonded with supporting layer, external shielding layer, thermal insulation layer and flame-retardant layer, the supporting layer includes internal shield, reinforcing rib
With the enhancement layer in outside, the reinforcing rib is adhesively fixed with the internal shield, and the reinforcing rib is integrated with the enhancement layer
Molding structure, the reinforcing rib is in filled with enhancing post, the internal shield and the external screen between triangular shape, the reinforcing rib
The material for covering layer is the excellent metallic copper of shielding properties, and the thickness of the thermal insulation layer is more than 2mm, and the flame-retardant layer is accordion
Pipe.
Further, the enhancement layer and the reinforcing rib are urethane rubber materials.
Further, the enhancing post is reinforcing glass cordage.
Further, the thermal insulation layer is polyurathamc or expanded polystyrene (EPS) material.
Further, it is waterproof epoxy resin adhesive for cohesive adhesive.
Further, the material of the flame-retardant layer is flame-proof polyvinyl chloride material.
A kind of cable resistant to bending of the utility model, compared with prior art with advantages below：
First, supporting layer described in the cable resistant to bending includes the internal shield, reinforcing rib and enhancing Rotating fields, institute
The supporting layer is assigned with the design and possesses the effect of shielding outer signals interference raising cable transmission efficiency, and makes the cable
Possesses the effect that resistance to compression bend resistance ability reaches enhancing strength cable.The enhancing post is combined with the reinforcing rib of triangle
Further improve enabling capabilities and tension, the impact resistance of the supporting layer.
Secondly, the structure design of flame-retardant layer described in the cable resistant to bending can be effectively by ground ambient temperature to the cable
Influence, that is, avoid making it crackle in small, broken bits occur and aging because the flame-retardant layer repeated and expand with heat and contract with cold.Once occur old
Changing the fire retardancy of so described flame-retardant layer will certainly be remarkably decreased, so the design can give full play to resistance for the flame-retardant layer
Fuel efficiency can provide strong guarantee.
Finally, it is additionally provided with external shielding layer in the cable resistant to bending further to reduce outer signals to electric in the cable core
The interference effect of signal, the design is combined with the internal shield promotes the electric signal transmission ability of the cable significantly to carry
Rise.The reasonable design of the insulation thickness then further enhances the heat insulating function of thermal insulation layer.

Embodiment
In order to be better understood from the utility model, traveling one is entered to the utility model with reference to specific embodiments and the drawings
The description of step.
As shown in Figure 1-2, a kind of cable resistant to bending, including cable core 1, the outside of the cable core 1 is arranged successively from the inside to the outside
And supporting layer 3, external shielding layer 4, thermal insulation layer 5 and flame-retardant layer 6 are bonded with by binding agent.The supporting layer 3 includes inner shield
Layer, reinforcing rib and the enhancement layer in outside, the reinforcing rib are adhesively fixed with the internal shield, the reinforcing rib and the enhancing
Layer is formed in one structure.The reinforcing rib is in filled with enhancing post 2 between triangular shape, the reinforcing rib.
The design assigns the supporting layer 3 and possesses the effect of shielding outer signals interference raising cable transmission efficiency, and makes
The cable possesses the effect that resistance to compression bend resistance ability reaches enhancing strength cable.The increasing of the enhancing post 2 and triangle
Strong rib is combined the enabling capabilities and tension, impact resistance for further improving the supporting layer 3.
The material of the internal shield and the external shielding layer 4 is the excellent metallic copper of shielding properties, the external shield
Layer 4 can further reduce interference effect of the outer signals to electric signal in the cable core 1.The design and the internal shield phase
It is obviously improved with reference to the electric signal transmission ability of the cable is promoted.The thickness of the thermal insulation layer 5 is more than 2mm.The thermal insulation layer 5
The reasonable design of thickness then further enhances the heat insulating function of thermal insulation layer 5.
In order that the enhancement layer and the reinforcing rib also have excellent buffering while with excellent support ability
Function, so being urethane rubber materials by the enhancement layer and the reinforcing rib.Because this material has chemical stability
By force, good, the good elastic performance of impact resistance and high-strength mechanical performance, so these materials just assign the enhancement layer
Also possesses corresponding advantage with the reinforcing rib.
In order to improve the pliability and tear-resistant ability of the enhancing post 2, so being reinforcing glass by the enhancing post 2
Cordage.This material has the advantages that quality is strong, intensity is high, can be reached while enhancing 2 mechanical performance of post is improved
Reduce the purpose of cable net weight.
In order that the thermal insulation layer 5 has good heat-insulation and heat-preservation ability, and it is low, light weight excellent with use cost
Point, so the thermal insulation layer 5 is designed as into polyurathamc or expanded polystyrene (EPS) material.
The flame-retardant layer 6 is accordion pipe.The structure design of the flame-retardant layer 6 can be effectively by ground ambient temperature to described
The influence of cable, that is, avoid making it crackle in small, broken bits occur and aging because the flame-retardant layer 6 repeated and expand with heat and contract with cold.Once
The fire retardancy for the so described flame-retardant layer 6 of aging occur will certainly be remarkably decreased, so the design can fill for the flame-retardant layer 6
Distribution waves flame-retarded efficiency and provides strong ensure.
In order that the flame-retardant layer 6 has good fire resistance, so being fire-retardant by the material design of the flame-retardant layer 6
Pvc material.The flame-proof polyvinyl chloride material is the pvc material added with flame retardant such as aluminium hydroxide.This
Planting material has cheap and easily processed into type advantage.
Finally, in order to which the cable possesses higher waterproof ability, so will be waterproof ring for cohesive adhesive
Epoxy resin adhesive.The design can set up the barrier that multiple tracks is difficult to go beyond to the hydrone in air, and then be prevented effectively from described
Because meeting hydrone with oxygen oxidation reaction occurs for cable core 1.Therefore, the design can effectively extend the service life of the cable.
Embodiment of the present utility model is described in detail above, but the content is only of the present utility model preferable
Embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.All impartial changes made according to the utility model scope
Change and improvement etc., all should still be belonged within this patent covering scope.
