Abstract
The invention discloses a piece-separating type central framework cable, comprising a cable core and a sheath; and the piece-separating type central framework cable is characterized in that the cable core consists of a subunit cable core arranged on a central framework, and the subunit cable core is composed of a plurality of pairs of stranded wires or a plurality of pairs of stranded wires provided with cross-shaped framework; the central framework is a sleeve provided with a plurality of separated pieces which are fixedly arranged on the circumference of the outer wall of the sleeve in a radial manner; the end surface of the central framework is in the shape of honeycomb, in which the subunit cable core is arranged; and the sheath is arranged outside the cable core which is probably provided with a shielding layer, and the sheath is tightly bound with the cable core as a whole. The piece-separating type central framework cable greatly improves the performance of near-end crosstalk and far-end crosstalk of the cable by means of the effective separation of the honeycomb-shaped piece-separating type central framework, has simple structure and convenient manufacture, and meets the increasing transmission requirement of modern communication better.
Description
Technical field
The present invention relates to cable, electric wire, specifically a kind of split blade type center framework cable.
Background technology
In recent years, because the development of information technology, very big variation has taken place to the transmission and the obtain manner of information in the user, and traditional voice communication can not be satisfied user's demand far away, and adopts digital communication more.Digital communication to the various electrical requirement of transmission cable than higher, especially the line of cable is had higher requirement to a cross-talk, existing cat5e cable requires to reach the transmission frequency of 100MHz and needs to support duplex applications, the cat6 cable requires to reach the transmission frequency of 250MHz, these cables general all by the core of 24 pairs or 25 strands to constituting, because the cable core logarithm ratio is more, thereby mutual crosstalk effect is bigger.
Summary of the invention
A kind of split blade type center framework cable of providing at the deficiencies in the prior art is provided, it adopts in the cable cellular split blade type center framework is set, with core to isolating effectively, thereby the line that has reduced cable is to a crosstalk effect, improve cable near-end crosstalk, far-end crosstalk performance greatly, thereby satisfied the transmission requirement that modern communications promotes day by day.
The concrete technical scheme that realizes the object of the invention is: a kind of cable of split blade type center framework, comprise cable core, sheath, be characterized in that cable core is made up of the subunit cable core that is arranged on the center framework, the subunit cable core is by number pair twist zygonemas or severals pair twist zygonemas formations of establishing " ten " font skeleton; Center framework is the sleeve pipe that is provided with several bursts, and burst is on the radial circumference that is installed in sleeve outer wall, and the center framework end face is cellular, is provided with the subunit cable core in its honeycomb; Sheath be arranged on or the cable core of provided with shielding layer outside, the tight bundle of sheath and cable core is one.
Described twisted wire thoroughly does away with stranded the forming of edge heart yearn by two.
The present invention adopts effective isolation of cellular split blade type center framework, improve greatly line to crosstalk problem, compared with prior art have simple in structure, easy to make, good electric property, improve the performance of cable near-end crosstalk, far-end crosstalk greatly, satisfied the transmission requirement that modern communications promotes day by day better.

Embodiment
Above-mentioned seven groups of subunit cable cores 2 that are made of four pair twist zygonemas 1 are together sent into cabler with split blade type center framework 3, " ten " font skeleton 8, extrude one deck sheath 5 equably by the cable extruder outside cable core 6 behind the stranded formation stable structure of stranding, sheath 5 is one with cable core 6 tight bundles.Process shielded type cable in this way and only need lapped shielding layer 4 outside cable core 6, being extruded one deck sheath 5 equably and tightly restrainted with cable core 6 outside the cable core 6 of lapped shielding layer 4 by the cable extruder then is one.
Above-mentioned seven groups of heart yearn groups 2 that are made of four pair twist zygonemas 1 are together sent into cabler with split blade type center framework 3, extrude one deck sheath 5 equably by the cable extruder outside cable core 6 behind the stranded formation stable structure of stranding, sheath 5 is one with cable core 6 tight bundles.Process shielded type cable in this way and only need lapped shielding layer 4 outside cable core 6, being extruded one deck sheath 5 equably and tightly restrainted with cable core 6 outside the cable core 6 of lapped shielding layer 4 by the cable extruder then is one.
Claims (2)
1. a split blade type center framework cable comprises cable core, sheath, it is characterized in that cable core is made up of the subunit cable core that is arranged on the center framework, and the subunit cable core is by number pair twist zygonemas or severals pair twist zygonemas formations of establishing " ten " font skeleton; Center framework is the sleeve pipe that is provided with several bursts, and burst is on the radial circumference that is installed in sleeve outer wall, and the center framework end face is cellular, is provided with the subunit cable core in its honeycomb; Sheath be arranged on or the cable core of provided with shielding layer outside, the tight bundle of sheath and cable core is one.
