CN203573676U - Highly soft cable - Google Patents

Abstract

The utility model provides a highly soft cable which comprises a plurality of insulated wire cores and a polyamide filament isolation layer. Each of the insulated wire cores is formed by a conductor which is formed by twisting copper wires and a polyethylene insulated layer outside the conductor. Each of the insulated wire cores is divided into inner and outer layers. The inner layer insulated wire core and the outer layer insulated wire core are separated by a polyamide filament fastening layer. The polyamide filament isolation layer is arranged outside the outer layer insulated wire cores. The inner layer insulated wire core is six insulated wire cores which are uniformly arranged in a ring. The cable has the advantages of high softness, high temperature resistant and strong insulation strength.

Description

A kind of highly-flexible cable

Technical field

The utility model relates to a kind of power cable, relates in particular to a kind of highly-flexible cable.

Background technology

Along with the fast development of China's economy, increasing cable requires highly-flexible performance, in the plant equipment such as manipulator on sprocket wheel, streamline, multi-function robot, harbour plant, crane, wind turbine generator, electric wire is when work, stand for a long time unidirectional or compound bending, what have stands the mechanisms such as unidirectional or bidirectional torsion for a long time, and the conductor monofilament of cable ruptures by root, finally cause cable conductor complete rupture, cable is scrapped.Current rubber sleeve flexible cable ubiquity is short useful life, can only use some months, and the too early bending failure of copper conductor and fracture just occur the even less than having for one month.

Utility model content

Technical problem to be solved in the utility model is to overcome defect of the prior art, and a kind of highly-flexible cable is provided, and this cable has the features such as highly-flexible, high temperature resistant and dielectric strength be large.

For solving the problems of the technologies described above, the utility model provides a kind of highly-flexible cable, comprise many insulated wire cores and Polyamide Yarns separator, wherein: the polyethylene layer outside conductor and conductor that soft copper skein silk closes forms insulated wire cores, insulated wire cores is divided into inside and outside two-layer, between primary insulation core and outer layer insulation core, by Polyamide Yarns, tighten layer and separate, outer layer insulation core is provided with Polyamide Yarns separator outward, the six roots of sensation insulated wire cores that primary insulation core is even annular array.

As further improvement of the utility model, softening copper wire is stranded forms by 0.12 for conductor.

As further improvement of the utility model, 12 insulated wire cores that outer layer insulation core is even annular array.

The beneficial effect that the utility model reaches: the utility model provides a kind of highly-flexible cable, separator is formed by Polyamide Yarns braiding, has highly-flexible, the advantage such as wear-resisting, high temperature resistant.

Accompanying drawing explanation

Fig. 1 is the structural representation of highly-flexible cable.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.

As shown in Figure 1, the utility model provides a kind of highly-flexible cable, comprise many insulated wire cores and Polyamide Yarns separator 4, wherein: the polyethylene layer 2 outside conductor 1 and conductor 1 that soft copper skein silk closes forms insulated wire cores, insulated wire cores is divided into inside and outside two-layer, between primary insulation core and outer layer insulation core, by Polyamide Yarns, tighten layer 3 and separate, outer layer insulation core is provided with Polyamide Yarns separator 4 outward, the six roots of sensation insulated wire cores that primary insulation core is even annular array; Softening copper wire is stranded forms by 0.12 for conductor 1; Outer layer insulation core is 12 insulated wire cores of even annular array.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection range of the present utility model.
