Abstract
The invention discloses a fan-shaped framework cable which comprises a plurality of sub-cable cores; each sub-cable core comprises three groups of cable core pairs and sub-framework moulds arranged among the three groups of cable core pairs, wherein each sub-framework mould comprises three frameworks, and the included angle between every two adjacent frameworks is 120 degrees; each cable core pair comprises two conductors which are twisted together, and a covering layer arranged outside the conductors; a sub-sheath is arranged at the periphery of the three groups of cable core pairs and the sub-framework moulds; a framework mould is arranged among every three sub-cable cores; the structures of the framework moulds are the same as those of the sub-framework moulds. The three groups of cable core pairs of the plurality of sub-cable cores of the fan-shaped framework cable are separated from one another by the sub-framework moulds, so that the problem of heat dissipation of the cable core pairs can be solved, and a larger space is available for movement among the cable core pairs when the cable is twisted or repeatedly bent by external force since the included angle between every two adjacent frameworks is 120 degrees; an insulating layer arranged at the periphery of the conductors of each cable core pair does not easily crack, so that the fan-shaped framework cable is good in carrier performance.
Description
Technical field
The present invention relates to technical field of electric wires and cables, relate in particular to a kind of fan-shaped framework cable.
Background technology
Electric wire is widely used in the every field of industrial production and life.In recent years, due to the development of information technology, very large variation has occurred to transmission and the obtain manner of information in the user, and traditional voice communication can not meet user's demand far away, and more adopts digital communication.Digital communication is higher to the various electrical requirement of transmission cable, especially cross-talk between the line of cable pair is had higher requirement, existing cable general all by multipair stranded core to forming, because the cable core logarithm ratio is more, occupy space quite large, and mutual crosstalk effect is larger.
For this reason, application number is 200920211455.2, the patent that name is called " a kind of piece-separating type central framework cable " discloses a kind of framework cable, comprise cable core, sheath, be characterized in that cable core is comprised of the subunit cable core be arranged on center framework, the subunit cable core consists of several pair twist zygonemas or the several pair twist zygonemas of establishing " ten " font skeleton.This framework cable adopts effective isolation of cellular piece-separating type central framework, can improve the crosstalk problem between line pair, but because skeleton is " ten " font, be positioned at an intraskeletal subunit cable core of " ten " font when being subject to external force torsion or alternating bending, because every two adjacent subunit cable core angles are 90 degree, make originally and easily ftracture with regard to very thin insulating barrier, and stressed rear stress is concentrated the reduced cross-sectional that makes conductor, affect the current-carrying performance of conductor, and relatively still comparatively dense distributes, radiating effect is poor, and long-term the use easily caused security incident.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of fan-shaped framework cable.
A kind of fan-shaped framework cable that the present invention proposes, by a plurality of sub-cable cores, formed, each described sub-cable core comprise three groups of cable cores to and be located at described three groups of cable cores between sub-skeleton pattern, described sub-skeleton pattern comprises three skeletons, and the angle of every two adjacent described skeletons is 120 degree.
Further, each described cable core is to comprising two conductors that twist together and being positioned at the outer coating layer of conductor.
Further, the periphery of each described conductor is by interior and be provided with screen and insulating barrier outward.
Further, described three groups of cable cores pair are provided with sub-sheath with sub-skeleton pattern periphery.
Further, be provided with skeleton pattern between every three sub-cable cores, and described skeleton pattern is identical with the structure of described sub-skeleton pattern.
Preferably, the material of described sub-skeleton pattern is insulating material.
Preferably, the material of described sub-skeleton pattern is flexible material.
In the present invention, three groups of cable cores of a plurality of sub-cable cores of described fan-shaped framework cable between with sub-skeleton pattern interval, not only can solve cable core between heat dissipation problem, and because the angle of adjacent skeleton is 120 degree, when cable is subject to external force torsion or alternating bending, cable core pair and cable core between larger space operation is arranged, the insulating barrier of the conductor periphery that cable core is right is not easy to crack, carrier property is good.
