Description
Technical field
The utility model belongs to power cable technical field, more particularly, to a kind of bend resistance cable.
Background technology
Cable becomes increasingly complex, not only can as a kind of essential transmission line, its application environment in industrial development
Connected up or use during bending operation and be broken, can also because it is boisterous influence and be broken, such as hail, wind
The weather such as white sleet.Fracture, which occurs, for cable will make conveying signal interruption, cause to use failure, to service worker and user's all bands
It is inconvenient to come.
Utility model content
In view of this, the utility model is directed to a kind of bend resistance cable, with the shortcoming to solve the above problems.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of bend resistance cable, including cable core, reinforcer, filler material, insulating layer, flame retardant coating, shielded layer and protective layer,
It is star structure in the middle part of the reinforcer, reinforcing rib, the insulation is outward extended with each vertex of the star structure
Layer surrounds the periphery of multiple reinforcing ribs, and multiple cables core are respectively distributed to reinforcing rib adjacent two-by-two and insulating layer is formed
Region in, the cable outer core wraps successively to filler material, the insulating layer outer wall is filled between reinforcer and insulating layer
It is covered with flame retardant coating, shielded layer and protective layer.
Further, the cable core includes conductor cores and is coated on the conductor cores insulating layer of conductor cores outer wall surface.
Further, the star structure intermediate throughholes, the through hole is interior to be equipped with the reinforcement for being fitted tightly over through-hole wall
Core.
Further, each side of the star structure is radian and the arc of the homogeneous cause of chord length.
Further, the cable core and insulating layer are tangent, and the cable core and the curved edge or phase of star structure
Two adjacent reinforcing ribs are tangent.
Further, each reinforcing rib both sides are equipped with aircraft cable.
Further, the insulating layer is vinyl fluoride silastic-layer.
Further, the flame retardant coating is low smoke, zero halogen polyolefine material.
Further, the shielded layer is aluminium foil.
Further, the protective layer is pvc material.
Relative to the prior art, bend resistance cable described in the utility model has the advantage that：
Bend resistance cable described in the utility model is uniformly set up cable interior zone separately by the reinforcer of star structure,
And cable core is limited between star structure and insulating layer, increase the intensity of cable, improve resistance foreign impacts power and
The ability of pressure, reduces the line accident caused by fracture, improves the reliability and security of cable；It it also avoid multiply at the same time
Cable core is twisted opposite slipping phenomenon between mode cable core caused by bending operation of connection, so as to avoid in cable
The problem of portion is loose occurs.
Brief description of the drawings
The attached drawing for forming the part of the utility model is used to provide a further understanding of the present invention, this practicality is new
The schematic description and description of type is used to explain the utility model, does not form the improper restriction to the utility model.

Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of bend resistance cable, including cable core, reinforcer 3, filler material 6, insulating layer 7, flame retardant coating 8,
Shielded layer 9 and protective layer 10, the middle part of the reinforcer 3 is star structure, the star structure each vertex to extension
Stretching has reinforcing rib, and the insulating layer 7 surrounds the periphery of multiple reinforcing ribs, and multiple cables core are respectively distributed to adjacent two-by-two
Reinforcing rib and insulating layer 7 form region in, the cable outer core arrive between reinforcer 3 and insulating layer 7 filled with fill
Material 6,7 outer wall of insulating layer is coated with flame retardant coating 8, shielded layer 9 and protective layer 10 successively.
The cable core includes conductor cores 1 and is coated on the conductor cores insulating layer 2 of 1 outer wall surface of conductor cores.

Step increases the ability of cable resistance external forces.
Each side of the star structure is radian and the arc of the homogeneous cause of chord length, forms a positive star structure.
The cable core and insulating layer 7 are tangent, and the cable core and the curved edge of star structure or adjacent two
Reinforcing rib is tangent.
Each reinforcing rib both sides are equipped with aircraft cable 4, further improve the intensity inside cable.
The insulating layer 7 is vinyl fluoride silastic-layer.
The flame retardant coating 8 is low smoke, zero halogen polyolefine material.
