Technical Field

The utility model belongs to the technical field of wire and cable's technique and specifically relates to an anti wear-resisting flexible cable of dragging.

Background

At present, in the electric wire and cable with voltage class of 450/750V and below, the variety which can be used for frequent dragging, frequent moving, winding and reciprocating motion is not many, and the electric wire and cable is mainly a general-purpose rubber insulated flexible cable, the biggest defect of the cable is that the cable is not wear-resistant, and as long as on a stone pavement or other rugged places, once being dragged, pulled, dragged and scraped, the sheath and even the insulation of the cable can be pulled to be broken, and even the conductive core is pulled to be broken, so that the result is caused, therefore, the design of the anti-dragging wear-resistant flexible cable is necessary.

Disclosure of Invention

An object of the utility model is to provide an anti wear-resisting flexible cable that drags, it can use frequently need remove, drag, draw, do the occasion of forced reciprocating motion.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides an anti-drag wear-resisting flexible cable, includes a plurality of conductive core and oversheath, characterized by, conductive core includes circular conductor and insulating layer, has the reinforcing wire that is used for once strengthening between insulating layer and circular conductor.

By adopting the structure, the reinforcing wire is arranged between the insulating layer of the conductive wire core and the round conductor, so that the tensile property of the single conductive wire core can be improved.

The round conductor is formed by twisting a plurality of thin and soft copper wires.

With this structure, the circular conductor can be made to have a flexible characteristic.

The number of the conductive wire cores is two to ten.

And a conventional soft filling material and a reinforcing rope for secondary reinforcement are arranged between the conductive wire cores.

Adopt this structure, adopt between the conductive core and strengthen the rope as the secondary and strengthen to can improve the tensile strength of whole root flexible cable, prevent frequently dragging, draw or reciprocating motion in-process cable by the break, therefore be applicable to the occasion that needs frequently pull.

The insulating layer is formed by extruding and wrapping an elastomer material.

The outer sheath is formed by extruding and wrapping an elastomer material.

By adopting the material, the insulating layer and the outer sheath are made of elastomer materials, so that the material has the characteristics of wear resistance, acid and alkali resistance and the like, is suitable for other severe occasions, and is environment-friendly.

The reinforcing filaments are high-strength fiber filaments.

The reinforcing rope is a thin rope synthesized by high-strength fiber yarns.

Compared with the prior art, the anti-drag wear-resistant flexible cable has the advantages that:

the utility model discloses in it can the wide application in frequent coiling, remove, drag and draw, force the occasion of reciprocating motion, still can use in the great place of acid, alkali corrosivity to provide a durable, convenient, safe, reliable wire and cable for the society.

In the figure, 1, a conductive wire core; 1a, an insulating layer; 1b, a circular conductor; 2. an outer sheath; 3. binding a belt; 4. a conventional soft filler material; 5. reinforcing wires; 6. and reinforcing the ropes.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figure 1, the anti-drag wear-resistant flexible cable comprises a plurality of conductive wire cores 1 and an outer sheath 2, wherein the conductive wire cores 1 comprise round conductors 1b and insulating layers 1a, and reinforcing wires 5 for primary reinforcement are arranged between the insulating layers 1a and the round conductors 1 b.

By adopting the structure, the reinforcing wire 5 is arranged between the insulating layer 1a of the conductive wire core 1 and the round conductor 1b, so that the tensile property of the single conductive wire core 1 can be improved.

The round conductor 1b is formed by twisting a plurality of thin and soft copper wires, and in the present embodiment, the thin and soft copper wires are processed by using existing products available on the market.

With this structure, the circular conductor 1b can be made to have soft characteristics.

The number of the conductive cores 1 is two to ten, and in the present embodiment, the number of the conductive cores 1 is seven.

The conventional soft filling material 4 and the reinforcing ropes 6 for secondary reinforcement are arranged between the conductive wire cores 1; in the present embodiment, the conventional soft packing material 4 is a commercially available material; the reinforcing cords 6 are located between the conductive core 1 and the conductive core 1 except for the conventional soft filling material 4.

Adopt this structure, adopt between the wire sinle silk to strengthen 6 as the secondary to can improve the tensile strength of whole root flexible cable, prevent frequently dragging, draw or reciprocating motion in-process cable by the break, therefore be applicable to the occasion that needs frequently pull.

The insulating layer 1a is formed by extruding and wrapping an elastomer material.

The outer sheath 2 is formed by extruding and wrapping an elastomer material.

In this example, a commercially available polyester-based elastomer was used as the elastomer material.

By adopting the material, the insulating layer 1a and the outer sheath 2 are made of elastomer materials, so that the material has the characteristics of wear resistance, acid and alkali resistance and the like, is suitable for other severe occasions, and is environment-friendly.

The reinforcing filaments 5 are high strength filaments.

The reinforcing cords 6 are high-strength filament synthetic strings.
