It is twisted into, entire outside is surrounded by the coating of high-insulation, is located in the air or mounted in underground, water since cable is usually laid on multi rack
Bottom, so there is certain requirement for the flexibility of cable, many cables are during laying at present, not due to bending resistance curvature
Enough and crushing resistance is poor, so being easy for generating in crooked position during laying or after a period of time use disconnected
It splits, therefore we make this improvement, proposes a kind of flexible cable convenient for being laid with.
Utility model content
It is easily broken off to solve cable of the existing technology, the defect of stability difference, the utility model provides one kind just
In the flexible cable of laying.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of flexible cable convenient for being laid with of the utility model, including center fixed strip, core wire and protective layer, the center
The avris of fixed strip is fixedly connected by several support columns being fixed with the side of several insulating layers, the insulating layer
Be internally provided with core wire, the other side of the insulating layer is fixedly connected by trapezoidal fixed strip with the inner wall of wire sheathing, institute
The outer wall for stating wire sheathing is fixed with protective layer, the outer wall of the protective layer be arranged with it is several to protection ring, described in a pair
Several ceilings are uniformly provided between protection ring.
Further, it is fixedly connected by several arc brackets between two adjacent insulating layers.
Further, the arc bracket, support column and trapezoidal fixed strip are that elastomeric material is made.
Further, the ceiling is the ceiling with flexible and ductility.
Further, the inside of the wire sheathing is filled with filler made of Thermoplastic polyurethane elastomer material
Matter.
Compared with prior art, the utility model has the advantages that：This kind is convenient for the flexible cable being laid with, center
The design that fixed strip is used cooperatively by support column and insulating layer, can bending force that effectively buffer insulation layer is subject to, avoid outer
The bending force on boundary causes internal core to be broken；The design that insulating layer is connect by trapezoidal fixed strip with wire sheathing, Ke Yizeng
The connection area for adding metal net and insulating layer, improves the stability of insulating layer, while further increasing buffer capacity；Metal
The Thermoplastic polyurethane elastomer material filled inside braiding layer can increase the flexibility and the aqueous energy of oil resistant of cable entirety；If
The dry ceiling being equipped between protection ring and protection ring can flexibly be moved to the specific crooked position of cable, and specific aim improves
Intensity is protected, it is more practical.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of flexible cable convenient for being laid with, including center fixed strip 1, core wire 4 and protective layer 9, in
The avris of heart fixed strip 1 is fixedly connected by several support columns 2 being fixed with the side of several insulating layers 3, insulation
Layer 3 is internally provided with core wire 4, and the other side of insulating layer 3 is fixedly connected by trapezoidal fixed strip 6 with the inner wall of wire sheathing 7,
The outer wall of wire sheathing 7 is fixed with protective layer 9, and the outer wall of protective layer 9 is arranged with several to protection ring 10, a pair of of protection ring
Several ceilings 8 are uniformly provided between 10.
Wherein, be fixedly connected by several arc brackets 5 between two adjacent insulating layers 3, increase insulating layer 3 it
Between the compactness that connects, while improving the stability of cable entirety.
Wherein, arc bracket 5, support column 2 and trapezoidal fixed strip 6 are that elastomeric material is made, elastic rubber material
Material elasticity is good, and bending degree is high, can ensure good buffer capacity, to improve cable resist bending degree.
Wherein, ceiling 8 is the ceiling 8 with flexible and ductility, can be increased by manual extensive protection item 8 and be protected
Range is protected, the using flexible of ceiling 8 is improved.
Wherein, the inside of wire sheathing 7 is filled with filler, thermoplastic made of Thermoplastic polyurethane elastomer material
