Abstract

The utility model discloses a flat power cable with a double-layer insulation structure. The flat power cable comprises three sets of conductor assemblies; the exterior of four conductors of which the section is sector-shaped is wrapped with an inner insulation fluoroplastic layer, such that each set of conductor assembly can be formed; the exterior of each set of conductor assembly is wrapped with an outer insulation silicone rubber layer, a galvanized copper wire braided shielding layer and a protective layer sequentially; three elastic tensile belts of which the section is arc-shaped are distributed in the protective layer in a manner that the three elastic tensile belts form a structure shaped like a Chinese character ''pin''; the thickness of the elastic tensile belts is not larger than 1.5mm; the three sets of the conductor assemblies which are wrapped with the protective layers form a cable core; and the exterior of the cable core is provided with an outer sheath layer which is formed through extrusion molding. The flat power cable of the utility model is in novel structure design. According to the flat power cable of the utility model, the inner insulation fluoroplastic layers and the outer insulation silicone rubber layers are designed, and therefore, the insulation performance of the cable can be greatly improved, and at the same time, the elastic tensile belts are designed in the protective layers, and therefore, the tensile performance of the cable can be improved; and further, the cable has excellent flexibility and abrasion resistance.

Description

A kind of flat power cable with double-layer insulating structure

technical field:

The utility model relates to flat cable, relates in particular to a kind of flat power cable with double-layer insulating structure.

background technology:

Existing flat cable extrudes sheath and forms after being arranged in parallel by three or four insulated wire cores, cable after often mobile, 15mm especially ²and following small bore there will be disconnected core, sheath wearing and tearing and the poor phenomenon of insulation property, cause cable short useful life, and user loses large problem.

For meeting instructions for use, just need a kind of tension and the good flat cable of insulation property to replace existing flat cable, extend its useful life.

utility model content:

In order to make up prior art problem, the purpose of this utility model is to provide a kind of flat power cable with double-layer insulating structure, has improved insulation property and the stretch-proof performance of cable, extends the useful life of cable, guarantees the unobstructed of signal transmission.

The technical solution of the utility model is as follows:

Flat power cable with double-layer insulating structure; comprise three groups of conductor groups; it is characterized in that: every group of conductor group in three groups of described conductor groups is that fan-shaped conductor outer cladding fluoroplastics inner insulating layer forms by four cross sections; every group of conductor group is coated with silicon rubber external insulation layer, zinc-plated copper wire woven shield, protective layer outward successively; in protective layer, be provided with three and be isosceles triangle elastic reactance drawstring that distribute, that cross section is arc; the thickness of elastic reactance drawstring is not more than 1.5mm; three groups of conductor groups of coated protective layer form cable core, and the outer extrusion moulding of cable core has external sheath layer.

The described flat power cable with double-layer insulating structure, is characterized in that: described protective layer adopts styrene analog thermoplastic elastomer material extrusion moulding to form.

The utility model has the advantages that:

The utility model structural design is novel; the insulation property of cable by the design of fluoroplastics inner insulating layer, silicon rubber external insulation layer, have been improved greatly; simultaneously; design flexibility tension band in protective layer; improve the stretch-proof performance of cable; in addition, cable has good flexility, anti-wear performance.

accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

embodiment:

Referring to Fig. 1:

Flat power cable with double-layer insulating structure; comprise three groups of conductor groups; every group of conductor group in three groups of conductor groups is that fan-shaped conductor 1 outer cladding fluoroplastics inner insulating layer 2 forms by four cross sections; every group of conductor group is coated with silicon rubber external insulation layer 3, zinc-plated copper wire woven shield 4, protective layer 5 outward successively; in protective layer 5, be provided with three and be isosceles triangle elastic reactance drawstring 6 that distribute, that cross section is arc; the thickness of elastic reactance drawstring 6 is not more than 1.5mm; three groups of conductor groups of coated protective layer 5 form cable core, and the outer extrusion moulding of cable core has external sheath layer 7.

Protective layer 5 adopts styrene analog thermoplastic elastomer material extrusion moulding to form.
