Abstract

The patent discloses a category 6+ network cable, relating to the electronic information data cable technical field and aiming to solve the problem that for a present category 6+ network cable, line pairs and cross-shaped frameworks are easy to generate irregular displacement and stability thereof is difficult to control. The category 6+ network cable comprises an outer protective sleeve and a tearing rope, a cross-shaped isolation framework and four pairs of intertwisted core wires which are arranged in the outer protective sleeve; the core wires are composed of conductors and insulating layers cladding the conductors; inner walls of the outer protective sleeve possess sawtooth type grooves; end parts of the cross-shaped isolation framework are of closed angle shapes and are against the sawtooth type grooves; the cross-shaped isolation framework and the outer protective sleeve enclose four independent cavities, in which the four pairs of intertwisted core wires are uniformly distributed. The category 6+ network cable is especially suitable for network signal transmission.

Description

Category 6+network cable

Technical field

The utility model relates to electronic information data cable technical field, relates in particular to a kind of six class Network transmission lines that surpass of high-speed transfer.

Background technology

Normal use is to surpass five classes and six class utp cables in the computer network.Wherein, surpass five class transmission frequency 100MHZ, be mainly used in the low and middle-end building construction, six class twisted-pair feeders adopt the means such as high-quality or foam insulating material greatly to improve the character of transmission medium, transmission frequency can reach 250MHZ, but compares with the optical fiber of trunk or a certain distance is arranged.

The category 6+network cable transmission frequency reaches 500MHZ, is a kind of communications cable of carry high frequency digital signal.Usually adopt crossing skeleton to come shielding wire pair in the cable, avoid one group of line to sinking into another group line in the slit between two wires, thus reduce line to cross-talk.But the crossing skeleton limited space, abnormal displacement easily occurs with the central cross skeleton in line pair, even course of processing control is good, also may cause torsional deformation when threading is pullled, wayward its stability.

The utility model content

In existing category 6+network cable, abnormal displacement easily occurs with crossing skeleton in line pair, wayward its stable problem, and the purpose of this utility model provides the category 6+network cable that a kind of processing technology is simple and stability is good.

The technical scheme that its technical problem that solves the utility model adopts is: comprise outer jointing jacket, be arranged in the described outer jointing jacket tear rope, skeleton and four strand heart yearns isolated in cross; described heart yearn is made of conductor and the insulating barrier that is coated on described conductor outside; described outer jointing jacket inwall has the sawtooth pattern groove; described cross isolation skeleton end is tip-angled shape and offsets with described sawtooth pattern groove inwall; described cross isolation skeleton and described outer jointing jacket are enclosed four separately cavitys independently, and described four strand heart yearns are distributed in described four cavitys.

Further, the parallel distance of described each strand heart yearn is greater than 3 times of conductor diameter.

The space width D of described sawtooth pattern groove is 1.2～1.7mm, and gullet depth H is 0.6～0.9mm, and described sawtooth pattern groove is 0.4mm apart from the distance h of described outer jointing jacket outer wall minimum.

The length of described cross isolation skeleton is 5.0～8.0mm.

The effect of this patent is:

One, the utility model adopts the outer jointing jacket with sawtooth pattern groove; utilize the spacing principle of sawtooth; eliminate line to and crossing skeleton between incident displacement when stranded; guarantee between line pair and the crossing skeleton stranded stable; thereby the stability of control cable performance, its cost is low, processing technology is simple.

Two, conventional wire cable is outer by spatial limitation because being subjected to, and its inner cross skeleton is less, and heart yearn and skeleton easily are subjected to displacement when stranded, cause unstable properties.The crossing skeleton end that the utility model adopts is tip-angled shape and offsets with the groove inwall, and skeleton can be with the line that is subjected to displacement to retracting original position with outer the combination by the sawtooth pattern groove, guarantees that cable performance stablizes.

Three, traditional cable because of be subjected to spatial limitation can not guarantee line to spacing, can't reduce to greatest extent line to interference.The utility model adopt crossing skeleton and outer combined guarantee respectively to organize line to spacing greater than 3 times of conductor diameter, thereby reduce to greatest extent line to interference.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples;

Fig. 1 is the structural representation of the utility model cable cross section;

The number in the figure explanation:

1-outer jointing jacket 2-tears rope

3-insulating barrier 4-conductor

5-heart yearn 6-cross isolation skeleton

Embodiment

In conjunction with Fig. 1 category 6+network cable of the present utility model is described; it comprise insulation outer jointing jacket 1, be arranged at and tear rope 2, cross isolation skeleton 6 and four strand heart yearns 5 in the outer jointing jacket 1, heart yearn 5 is made of conductor 4 and the insulating barrier 3 that is coated on conductor 4 outsides.Outer jointing jacket 1 inwall has the sawtooth pattern groove; cross isolation skeleton 6 ends are tip-angled shape and offset with sawtooth pattern groove inwall; cross isolation skeleton and outer jointing jacket inwall are enclosed four separately cavitys independently; four strand heart yearns 5 are distributed in four cavitys; effectively four strand heart yearns 5 in the cable are isolated; in addition, arrange in therein the cavity and tear rope 2.The parallel distance of each strand heart yearn 5 is greater than 3 times of conductor 4 diameters, so that cable wire dies down to an interference performance, thereby reduces the internal crosstalk of cable.

The degree of depth sawtooth pattern groove structure that outer jointing jacket 1 inwall adopts is for the position that makes four strand heart yearns 5 relatively more is fixed, the distortion that is not easy to be moved, thereby make line between the distance maintenance uniform and stable.Simultaneously, also can increase the space of cable inside, improve the anti-cross-talk performance of cable, solve the in actual applications problem of high-frequency signal phase mutual interference between cable.Cross isolation skeleton 6 adopts foaming structure, can reduce the dielectric constant of cross isolation skeleton 6, improve its insulation characterisitic, guarantee that cable is under solid insulation and non-shielding construction, improve line to the cross-talk performance, guarantee the anti-combustion characteristic of safety and enough decay surpluses of product.

The space width D of sawtooth pattern groove is 1.2～1.7mm, and gullet depth H is 0.6～0.9mm, and the sawtooth pattern groove is 0.4mm apart from the distance h of outer jointing jacket outer wall minimum.The length of cross isolation skeleton 6 is 5.0～8.0mm.

Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; in order to make those skilled in the art can better understand this patent content; should not be understood as the restriction to this patent protection range; change or modify so long as disclose spiritual any being equal to of doing according to this patent, all fall into this patent protection range.
