Abstract

The utility model discloses a reinforced computer flexible cable which comprises two conductor sets. Each conductor set is composed of two conductors intertwisted with each other, and insulating layers are wrapped outside the two conductors. A winding layer, which is wound by glass fiber in an overlapped manner and has a flat cross section, is wrapped outside the two conductor sets, wherein a winding cover rate of the winding layer is not less than 30%. The two conductor sets wrapped with the winding layer is arranged in a longitudinal manner to form a cable core. A belting layer is wrapped outside the cable core. A filling layer made from a refractory material is filled between the belting layer and the cable core. The filling layer is equipped with filling ropes braided by terylene yarn on two sides of the two conductor sets. A shielding layer braided by copper wires, an armor layer and a sheath layer are successively wrapped outside the belting layer. The reinforced computer flexible cable has the advantages of reasonable design, superior structural compactness, fine strength and prolonged service life.

Description

A kind of reinforced computer flexible cable

Technical field

The utility model relates to the computer cable field, relates in particular to a kind of reinforced computer flexible cable.

Background technology

Cable is in order to transmit electricity (magnetic) ability, information and the wire product of realizing the electromagnetic energy conversion.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire comprises that mainly bare wire, electromagnetic wire and electrical equipment and electrical are with insulated electric conductor, power cable, telecommunication cable and optical cable.

The utility model is applicable to that industries such as ac rated voltage 300/500V electric power, metallurgy, petrochemical industry are that main automatic control system, computer distributed control system, automation control system made control line and detecting instrument instrument computer cable with the electronic computer.

Previous computer flexible cable, structure are compact inadequately, intensity is lower, are difficult to satisfy the demand of operational environment, directly influence the useful life of cable.

The utility model content

To the prior art problem, the purpose of the utility model provides a kind of reinforced computer flexible cable, and compact conformation has that travelling performance is good, flexibility is good and the advantage of anti-external impact.

The technical scheme of the utility model is following:

Reinforced computer flexible cable; Comprise two conductor groups; Described two conductor groups are enclosed with by two outsides respectively that the conductor of insulating barrier is each other stranded to be constituted; It is characterized in that: it is the lapping layer of flat that the cross section of the overlapping wrapped formation of glass fibre belt is adopted in described two conductor groups outside respectively, and the wrapped rate of putting up of lapping layer is not less than 30%, the vertical formation cable core of putting of two conductor groups of parcel lapping layer; Cable core is coated with belting layer; Be filled with the packed layer that refractory material constitutes between belting layer and the cable core, be respectively equipped with the gasket for packing that the dacron thread braiding constitutes in the packed layer of two conductor group both sides, the belting layer outside is enclosed with screen, armour, the restrictive coating that the copper wire braiding constitutes successively.

Described reinforced computer flexible cable is characterized in that: described armour adopts two wrapped formations of steel band.

Described reinforced computer flexible cable is characterized in that: it is flame-proof polyvinyl chloride that described insulating layer material adopts material.

Described reinforced computer flexible cable is characterized in that: it is fluoroplastics that described restrictive coating adopts material.

The utility model has the advantages that:

The utility model reasonable in design is divided into groups two mutual stranded formation conductor groups of conductor to four conductors of cable; The outer wrapped section constitution flat of conductor group; Two vertical formation cable cores of putting of conductor group are provided with gasket for packing simultaneously in packed layer, make that the structural compactness of cable is superior; Intensity is good, has prolonged the useful life of cable.
