Description

A kind of control cable with irregular octagon skeleton

Technical field

It the utility model is related to field of cable technology, more particularly to a kind of control electricity with irregular octagon skeleton Cable.

Background technology

Control cable is cable for transmission of control signals, and control cable mainly solves that transmission signal is weak, signal is done Disturb, distorted signals the problems such as.The cable of prior art is mainly made up of cored wire, insulating barrier and screen layer and sheath, insulating barrier The outside of cored wire is wrapped in, the effect of screen layer is the influence for avoiding external electromagnetic field to conveying signal.Therefore screen layer is in electricity Played an important role in cable, and the cable of prior art sets existing defects problem in terms of relevant shielding, causes cable Jitter in transmission signal be present, or cause the phenomenon of signal interruption.Also exist in the design of the other construction of cable Various shortcomings, cause cable service life short.

Utility model content

The defects of the utility model purpose is exactly to make up prior art, there is provided one kind carries irregular octagon skeleton Control cable.

The utility model is achieved through the following technical solutions：

A kind of control cable with irregular octagon skeleton, includes silicon rubber skeleton, described silicon rubber skeleton It is to be spliced into integrally formed, described irregular octagon bone by multiple cross sections for irregular octagon skeleton unit The cross section of frame unit is symmetrical octagon, and symmetrical center line is the connecting line of interior angle one and interior angle five, wherein interior angle One is 120 degree, and interior angle five is 60 degree, and interior angle two and interior angle eight are 120 degree, and interior angle three and interior angle seven are right angle, interior angle four Be 240 degree with interior angle six, be respectively equipped with core inside each irregular octagon skeleton unit, described core be by What conductor and the low-smoke low-halogen polyvinyl chloride insulation layer being coated on the outside of conductor and compound inslation screen layer were formed, in silicon rubber The outside of skeleton is coated with corrugated aluminium sheath layer, water resistance aramid fiber yarn packed layer, the composite filled layer of pearlife and three layers of protection outside successively Layer, is additionally provided with a plurality of flexible wire ropes and elastic polyurethane rod between silicon rubber skeleton and corrugated aluminium sheath layer.

Described compound inslation screen layer from inside to outside successively by semiconductive fluorubber internal shield, fluorubber insulating barrier, Semiconductive fluorubber external shielding layer forms.

Three layers of described external protection are followed successively by silver-plated nickel strap armor, butyronitrile insulating barrier and nickel modeling copper strips from inside to outside Armouring pe sheath layer.

Described flexible wire ropes include organic fiber wire rope core, and internal layer steel is sequentially provided with outside the organic fiber wire rope core Cord and cover wire rope.

Silicon rubber skeleton be by multiple cross sections be irregular octagon skeleton unit be spliced into it is integrally formed, it is described The cross section of irregular octagon skeleton unit be symmetrical octagon, irregular octagonal design causes cable Structure it is more novel, symmetrical center line is the connecting line of interior angle one and interior angle five, and the design of each interior angle, makes splicing more The convenience added, cable internal structure is more firm, and arrangement is more orderly, more preferable to the protecting effect of the core of inside, structure letter It is single firm without losing, it is economical and practical.

Compound inslation screen layer is from inside to outside successively by semiconductive fluorubber internal shield, fluorubber insulating barrier, semiconductive Fluorubber external shielding layer forms, and semiconductive fluorubber internal shield and semiconductive fluorubber external shielding layer are around pouch-type or extrusion type Fluorubber material, fluorubber insulating barrier are around pouch-type or extrusion type fluorubber material, ensure that cable flexible nature and resistance to height Temperature characteristics, and caused noise signal minimizes in itself by cable.

Three layers of external protection are followed successively by silver-plated nickel strap armor, butyronitrile insulating barrier and nickel modeling copper strips armouring and gathered from inside to outside Ethene restrictive coating, abrasion resistant effect is more preferable, and service life is longer.

Flexible wire ropes wire rope core is organic fiber wire rope core, and inside, elastic fiber material is filled between cover wire rope, So that steel wire rope has preferable pliability, solve the problems, such as that existing steel wire rope pliability is low, bending property is poor.

The composite filled layer of pearlife is that one kind is made up of material from acidic volcanic glass matter lava through broken, preheating, calcining expansion Have loose structure, white, granular loose material, have capacity is small, thermal conductivity factor is low, chemical stability is good, non-ignitable, nothing The characteristic such as malicious, tasteless, sound-absorbing, increase the heat resistance of cable.

The utility model has the advantages that：The utility model employs the silicon that irregular octagon skeleton unit is spliced Rubber skeleton, simple in construction, in light weight, design is graceful, and noise is small, and pliability is high, and the life-span is longer, and heat-resisting waterproof effect is more preferable.
