Abstract

The utility model discloses a novel cable which comprises a plurality of cable cores and a sheath, wherein the cable cores are arranged in the sheath; each cable core is in a three-layer structure, and is composed of a conductor, an insulating layer and an inner cladding from inside to outside; the insulating layer is made from refractory polymer fluoroplastics, and the inner cladding is made from TPU (thermoplastic polyurethane); the sheath is in a two-layer structure, and is composed of a fixed layer and an outer cladding; and the outer cladding is made from TPU. The insulated cable is free from abrasion and has long service life under the long-term motion conditions; and the cable has high shock resistance, extrusion resistance and tensile strength, ensures favorable softness, and is suitable for frequent motion.

Description

A kind of novel cable

Technical field

The utility model relates to the cable technology field, particularly a kind of novel cable.

Background technology

Cable is widely used in occasions such as generator, oil, chemical industry, mine, and cable needs high-frequency mobile and crooked in above environment for use, and easy mechanical position produces frequently and rubs in mobile with crooked process; Cause the breakage of cable cover(ing), thereby cause shorten the useful life of cable, also can produce potential safety hazard when serious; Existing common cable, resistance to wear is not enough, and coefficient safe in utilization is low; Useful life is short, is difficult to satisfy the requirement of the used cable of present various harsh occasions.

The utility model content

To the weak point of above-mentioned prior art, the utility model provides a kind of cable with high abrasion insulation.

To achieve these goals; The technical scheme that the utility model adopts is: a kind of novel cable, comprise cable core and sheath, and several cable cores are arranged on the inside of sheath; Said cable core is a three-decker; It is respectively conductor, insulating barrier, inner cladding from inside to outside, and said insulating barrier is that resistant to elevated temperatures polyfluorine plastics are processed, and inner cladding is processed for the TPU material; Said sheath double-layer structure is respectively fixed bed, surrounding layer to outward in it, and said surrounding layer is processed for the TPU material.Be provided with resistant to elevated temperatures insulating barrier in the utility model, surrounding layer and inner cladding are processed by the TPU material, because TPU is wear-resisting macromolecular material; Make conductor obtain the multilayer protection; Can guarantee that cable operates under the long-term condition that moves, not frayed, the useful life of prolongation cable.

As preferably, said cable core is three, and three cable cores are glued at one.The copper wire part of heart yearn glued together does not so contact mutually, has prevented the generation of short-circuit state, and copper wire is condensed in together, and the ability that makes heart yearn bear pulling force strengthens.

As preferably, the gap location between said cable core and the sheath is filled with packed layer.This packed layer position polyethylene is processed, and can realize the function of metal armouring, is equivalent to the effect of air bag, can realize stronger shock resistance, anti-extrusion ability.

Compared with prior art, the beneficial effect that brings of this utility model is:

1, the utility model is under the long-term condition that moves, and is not frayed, long service life.

2, the utility model has stronger shock resistance, anti-extrusion ability, tensile strength, guarantees that also cable has flexibility preferably simultaneously, suitable frequent moving.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.

Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.

Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.

Referring to Fig. 1, a kind of novel cable comprise that cable core 2 and 1, three cable core 2 of sheath are arranged on the inside of sheath 1, and three cable cores 2 is glued at one.Said cable core 2 is a three-decker, and it is respectively conductor 2-1, insulating barrier 2-2, inner cladding 2-3 from inside to outside, and said insulating barrier 2-2 is that resistant to elevated temperatures polyfluorine plastics are processed, and inner cladding 2-3 processes for the TPU material; Said sheath 1 double-layer structure is respectively fixed bed 1-2, surrounding layer 1-1 to outward in it, and said surrounding layer 1-1 processes for the TPU material.Gap location between cable core 2 and sheath 1 is filled with packed layer 3, and this packed layer 3 is processed for polyethylene, can realize the function of metal armouring, is equivalent to the effect of air bag, can realize stronger shock resistance, anti-extrusion ability; Surrounding layer 1-1 processes with the TPU material, and the TPU material has good wear resistance, can make cable also can not be worn after the use for a long time, has prolonged the useful life of cable.And inner cladding 2-3 processes with the TPU material, makes inner cladding 2-3 and surrounding layer 1-1 reduce the wearing and tearing to inner cladding 2-3 when using, and is of value to its conductor inside of protection 2-1.
