Abstract
The utility model relates to a take two six types of net twines of two Y shape skeletons, two outer ends jag of skeleton are Y shape, and skeleton body spacing department is provided with the signal line pair, and the periphery of skeleton and signal line pair is provided with the sheath. The utility model discloses having guaranteed the relatively stable of conductor and insulation size, having guaranteed the concentricity and the electric capacity stability of heart yearn, reduced internal crosstalk, reduced the influence that causes because of the reason of concentricity, can prevent inner structure's is loose, also can reduce the sheath material in addition to transmission performance's influence, greatly reduced the crosstalk of signal line pair between the cable.
Description
Technical Field
The utility model relates to a non-shielding twisted pair cable, in particular to take super six types of net twines of two Y shape skeletons.
Background
In the actual wiring of net twine, especially when laying wire in the floor of building, trunk access or computer lab, data center, have many net twines in a narrow and small space relatively, the while operation has the problem of a large amount of signal crosstalk each other, influences the transmission rate of net twine.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a super six types of net twines of modified reduce the crosstalk of signal line pair between the cable, reduce the influence because of the reason of concentricity causes.
The purpose of the utility model is realized like this. The super-six-type network cable with the double Y-shaped frameworks comprises frameworks and conductors, wherein insulating layers are wrapped on the peripheries of the conductors, the conductors are arranged side by side to form signal line pairs, two outer ends of each framework are Y-shaped in a split mode, the signal line pairs are arranged at the space positions of the framework bodies, and protective sleeves are arranged on the peripheries of the frameworks and the signal line pairs.
The utility model discloses guaranteed the relative stability of conductor and insulation size, guaranteed the concentricity and the electric capacity stability of heart yearn, reduce internal crosstalk, reduced the influence that causes because of the reason of concentricity, can prevent inner structure's is loose, can also reduce sheath material in addition to transmission performance's influence, greatly reduced the crosstalk of signal line pair between the cable.
Drawings
Fig. 1 is a schematic cross-sectional structure of the present invention.
In the figure: 1. conductor, 2 insulating layer, 3 signal line pair, 4 skeleton, 5 sheath.
Detailed Description
The present invention will be further explained with reference to the drawings and examples. Referring to fig. 1, the super-six types of network cables with double Y-shaped frameworks comprise frameworks 4 with two outer ends in a Y-shaped fork shape and conductors 1 with insulating layers 2 wrapped on the peripheries, wherein the conductors 1 are arranged side by side to form signal pairs 3, a pair of signal pairs 3 is respectively arranged between the body spaces of the frameworks 4, and sheaths 5 are arranged on the peripheries of the frameworks 4 and the signal pairs 3.
The utility model discloses a conductor 1 adopts the oxygen-free copper line, and nominal diameter is 0.57 mm. The insulating layer 2 is made of high-frequency communication grade high-density polyethylene material and has the characteristics of high stable dielectric constant, low dissipation factor, metal ion passivation and the like. The framework 4 adopts a two-way Y-shaped separation framework with two ends, effectively separates the four pairs of signal wire pairs 3 of the network wires, plays a supporting role, enlarges the space between the network wire cables during the bundling comprehensive wiring and can reduce the external crosstalk. The sheath 5 is made of high flame retardant polyvinyl chloride material or low smoke halogen-free flame retardant polyolefin material.
The utility model discloses can guarantee the concentricity and the electric capacity stability of heart yearn effectively. The pair twisting of the signal wire pair 3 is carried out on a special pair twisting machine, and four pairs of signal wires 3 are set with different pair twisting pitches, such as: a set of typical pitches can be blue to 8.18 mm, orange to 11.29 mm, green to 8.85 mm and brown to 10.41 mm, so that the minimum common multiple of the line pair pitches in the cable finished product is as large as possible to reduce the internal crosstalk, and in addition, the back-twist active pay-off is adopted for pay-off, so that the influence caused by the concentricity is reduced. When cabling, four pairs of signal lines 3 are placed at four spaced fixed positions of the double-Y-shaped framework 4, and for the ultra-six types of non-shielding structures, the typical size of the double-Y-shaped framework 4 is about 5mm in length and 3.5mm in width. Generally, the cabling pitch is set to about 90 mm and twisted together. The sheath 5 is extruded on a sheath extruder in a manner of tightly sleeving an extruding pipe, so that the loosening of the internal structure can be prevented, and the influence of the sheath material on the transmission performance can be reduced. Because the double Y-shaped frameworks 4 are flat, the cables are twisted on the sheaths 5 to form an oval shape, the distance between the cables can be increased when the cables are closely arranged, and the crosstalk of signal wire pairs between the cables (external near-end crosstalk ANEXT and external far-end attenuation ratio AACR-F) can be greatly reduced.
