Abstract

The utility model discloses a resistant winding course removes flexible cable, including at least a set of cable conductor and outer protection jacket, its characterized in that, the cable conductor including restrainting of inlayer close the aramid fiber, the cladding is restrainted and is closed the conductive layer of aramid fiber and the insulating layer on coating conductor layer, the outer cladding of cable conductor has around the band, around the external sheath outer protection jacket of band. The utility model discloses on the soft cable structure's of original ordinary rubber cover basis, increased in the middle of cable conductor and bundle closed the aramid fiber structure, it adds the tensile strength that can improve the cable in the middle of the wire greatly, and does not influence bending property.

Description

A kind of resistance to mobile flexible cable that circumnutates

Technical field

This utility model relates to field of cable technology, more particularly to a kind of resistance to mobile flexible cable that circumnutates.

Background technology

Wires and cables industry is the second largest industry that China is only second to automobile industry, along with China's economic growth continuously and healthily, provides the huge market space, product variety Service Efficiency and domestic market occupation rate all more than 90% for cable products. In the cable of numerous kinds, rubber sleeve flexible cable is wherein indispensable a kind of type, it is to be conductor by the thin copper wire of multiply, a kind of soft moveable cable kind of outpacking rubber insulation and rubber sheath, it is widely used in various electric equipment, the such as movable power wire of daily-use electrical appliance, motor machine, electrical device and utensil, can use simultaneously under indoor or outdoor environmental conditions.

It is be made by rubber material that the resistance to cable that circumnutates in the market leads to, and conventional products is usually to increase and reduces cable joint square to meet the resistance to condition circumnutated, but cable is not long for service life, the easily broken core when frequently moving and bending.

Summary of the invention

This utility model overcomes the technological deficiency described in above-mentioned background, have devised a kind of long service life, the resistance to mobile flexible cable that circumnutates that tensile strength is high.

For solving the problems referred to above, this utility model be the technical scheme is that

A kind of resistance to mobile flexible cable that circumnutates; including least one set cable conductor and outer jointing jacket; it is characterized in that; described cable conductor includes the bundle of innermost layer and closes aramid fiber, is coated with the conductor layer of bundle conjunction aramid fiber and the insulating barrier of coating conductor layer; described cable conductor is coated with twining package tape, the external sheath outer jointing jacket of twining package tape.

Further, the conductor in described conductor layer is 6 class flexible conductors.

Further, described insulating barrier and outer jointing jacket are made by insulation rubber material.

Further, the laying up pitch of the described resistance to mobile flexible cable that circumnutates is 10-12 times.

Known via above-mentioned technical scheme, this utility model is on the basis of original common rubber sleeve flexible cable structure, in the middle of cable conductor, add bundle close aramid fiber structure, aramid fiber is that a kind of proportion is lighter, the material of special tension soft, special, it is added in the tensile property that can substantially increase cable in the middle of wire, and does not affect bending property. Aramid fiber also has radiation resistance, durability, excellent fire-retardant, heat resistance and stable chemical property, is well suited in cable industry and uses.

Meanwhile, this utility model reduces stranding joint square to 10-12 times when stranding, which not only adds the bending property of cable, and does not affect the intensity of cable, meet be frequently bended, the occasion of movement.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of reinforced aerial cable of this utility model;

Wherein, in figure: 1-bundle closes aramid fiber; 2-conductor layer; 3-insulating barrier; 4-twining package tape; 5-outer jointing jacket.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.

As shown in Figure 1; the utility model discloses a kind of resistance to mobile flexible cable that circumnutates; including least one set cable conductor and outer jointing jacket; described cable conductor includes the bundle of innermost layer and closes aramid fiber 1, is coated with the conductor layer 2 of bundle conjunction aramid fiber 1 and the insulating barrier 3 of coating conductor layer 2; described cable conductor be coated with prevent cable conductor bending time loose or deformation twining package tape 4; the outer layer of twining package tape 4 is also coated with outer jointing jacket 5, to guarantee the rounding of cable core and tight.

This resistance to mobile flexible cable that circumnutates is to add bundle in the middle of common cable conductor to close aramid fiber 1 structure, substantially increases the tensile property of cable so that it is can bear bigger mechanical external force, simultaneously also without influence on the bending property of self. This utility model also by reduce when stranding stranding joint square can adapt to be frequently bended, the occasion of movement, solve normal cable in frequently mobile and easily broken core when bending defect. Wherein, the laying up pitch of the resistance to mobile flexible cable that circumnutates is 10-12 times.

For further prioritization scheme, the conductor in described conductor layer 2 is 6 class flexible conductors, makes this cable be provided with more excellent flexibility.

For further prioritization scheme, described insulating barrier 3 is made by insulation rubber material with outer jointing jacket 5, except having good insulating properties, without the bending property affecting cable.

It should be noted that, the multiple amendment of the described above of the disclosed embodiments be will be apparent from for those skilled in the art, generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments. Therefore; this utility model is not intended to be limited to the embodiments shown herein; anyone should learn the structure change made under enlightenment of the present utility model, every have with this utility model same or like like technical scheme, belong to protection domain of the present utility model.
