Abstract

The utility model discloses a bending resistant cable which includes a fiber tight rope, a plurality of insulating wire cores, wrapping tapes and an outer sheath. The fiber close rope is arranged at the center and the outer part of the fiber close rope is evenly provided with at least one layer of insulating wire cores in an evenly-surrounding manner. Each layer of insulating wire cores is provided with a wrapping tape at the outside. The outermost layer of wrapping tape is provided with the outer sheath at the outside. The bending resistant cable uses a strand or twisted fiber rope as a core wire which is placed at the center of the cable, and the insulating wire cores are arrayed to be surrounding the fiber core in layers according to space ratio rule. Each layer of insulating wire cores is wrapped with a layer of smooth polyester tape so that slide between the wire cores is increased and it is prevented that self-lock is generated between layers and the wire cores do not slide. The structure saves a filling material of the cable so that the cable is compact in structure; the tensile strength of the whole cable and the sliding performance between the wire cores are enhanced and thus the service life of the cable is improved and it is prevented that during short-term use of a common cable, phenomena of bulge, bending and wire fracture and the like happen.

Description

A kind of resistance to bending cable

Technical field

The utility model relates to a kind of resistance to bending cable with better bendability and travelling performance.

Background technology

Along with the raising of national rate of industrial development, increasing to the crooked and mobile demand of electric wire of using, particularly control class cable.

These cables be mainly used in factory and mechanical structure, robot architecture, automatic technology, automobile and shipbuilding industry, track technology, mounting technique, control cubicle structure, etc. occasion and equipment.When cable is used in the occasion such as crooked, mobile, conductor by frequent crooked, give a discount.The cable pressurized of inner ring, outer ring cable tension, and also will be subject to certain pulling force in take-up, so this class cable is easy to fracture, need to possess good bendability and travelling performance.

Chinese patent literature CN101447244 discloses < < high tensile, resistance to crooked removal cable conductor > >, rely on the relative sliding between conductor to improve its bendability, yet conductor is multiply flexible conductor, irregular arrangement, realize slip very difficult, core itself still will slide and be crooked.

Utility model content

The purpose of this utility model is to provide a kind of bendability and the good resistance to bending cable of mobility.

The technical scheme that realizes the utility model object is a kind of resistance to bending cable, comprises fibre compact rope, a plurality of insulated wire cores, band and oversheath; Described fibre compact rope is arranged on center, and its outside is evenly around at least one deck insulated wire cores is set; Described every layer of insulated wire cores outer setting band; At outermost band outer setting oversheath.

Described each insulated wire cores outer setting talcum bisque.

A kind of resistance to bending cable according to claim 1 and 2, is characterized in that: described resistance to bending cable does not arrange packed layer.

Adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model by a kind of Split Down or stranded cordage as middle heart yearn, it is placed in the middle of cable, insulated wire cores is arranged around fibre core from level to level by space proportion rule, the smooth polyester belt of wrapped one deck between every layer of insulated wire cores, can increase the slip between core, prevent self-locking between layers and do not slide, this structure has been saved the packing material of cable, make its compact conformation, and the tensile strength of whole cable and the sliding between core and core have been strengthened, improved cable useful life, prevented that common cable is when short-term is used, there is bulge, give a discount, the phenomenons such as fracture of wire.

(2) the utility model can further improve its crooked sliding at insulated wire cores surface-coated talcum bisque, reduce friction.

Accompanying drawing explanation

For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below

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

Attached number in the figure is:

Fibre compact rope 1, insulated wire cores 2, band 3, oversheath 4.

Embodiment

(embodiment 1)

See Fig. 1, a kind of resistance to bending cable of the present embodiment, comprises fibre compact rope 1, a plurality of insulated wire cores 2, band 3 and oversheath 4.Fibre compact rope 1 is arranged on center, its outside 360 ° evenly around two-layer insulated wire cores 2 is set; Every layer of insulated wire cores 2 outer setting band 3; At outermost band 3 outer setting oversheaths 4.Each insulated wire cores 2 outer setting talcum bisque, with increase between insulated wire cores 2 and insulated wire cores 2 and fibre compact rope 1 between sliding.Cable core does not adopt packed layer.Band 3 adopts polyester belt, and polyester belt can reduce frictional force between layers.The size of fibre compact rope 1 is determined according to cable core number and size.Its stranding only need just can be realized on common equipment, and technique is simple.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.

Claims (3)
