Abstract
The utility model discloses an enhanced category 6 cable structure which comprises eight copper conductors, a cross skeleton formed by cross blades and vertical blades, a polyester belt layer, a single-side aluminum foil layer and a flame-retardant layer. In the eight copper conductors, two copper conductors form a first twisted wire, two copper conductors form a second twisted wire, two copper conductors form a third twisted wire and another two copper conductors form a fourth twisted wire. The cross skeleton forms a first cavity, a second cavity, a third cavity and a fourth cavity through the cross blades and the vertical blades, the first twisted wire is located in the first cavity, the second twisted wire is located in the second cavity, the third twisted wire is located in the third cavity and the fourth twisted wire is located in the fourth cavity. The polyester belt layer is wrapped on the first twisted wire, the second twisted wire, the third twisted wire, the fourth twisted wire and the cross skeleton, and the single-side aluminum foil layer and the flame-retardant layer are sequentially wrapped on the polyester belt layer. The enhanced category 6 cable structure improves input impedance of cables, and investment cost of raw materials is reduced due to the increased pitch.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of six types of constructions of cable that surpass.
Background technology
The ordinary numbers cable: the ordinary numbers cable, in order to improve input impedance (Z
0) and these two electricity function index parameters of crosstalk attenuation (comprising near-end crosstalk attenuation NEXT and far-end crosstalk attentuation ELFEXT); General in technological design; Can adopt the fine pith measures such as (average pitch about 12.2mms) of concentricity, improve above-mentioned two indexs up to the single line more than 98%, precision.But concentricity is not easy to reach in actual production up to single line more than 98% and accurate fine pith, and the ordinary production qualification rate is very low, and the final products performance also can't guarantee qualification rate in batches.
Along with the fast development of network technology and improving constantly of computing power; People are increasingly high to the comprehensive wiring system performance demands; Requirement to the cable fire grade is also increasingly high; But the competition of each manufacturer is more and more fierce also, how to guarantee under the minimum prerequisite of manufacturing cost, farthest to improve and improve the performance of products index and seem particularly important.
Summary of the invention
The utility model provides a kind of six types of constructions of cable that surpass, and this surpasses the input impedance that six types of constructions of cable have improved cable; And the increase pitch, thereby reduced the raw material input cost.
For achieving the above object, the technical scheme that the utility model adopts is: a kind ofly surpass six types of constructions of cable, comprising: eight copper conductors, all outer insulating layer coating of this copper conductor; Two copper conductors are formed first strand to line in said eight copper conductors, and two copper conductors are formed second strand to line; Two copper conductors are formed the 3rd strand to line; Two copper conductors are formed the 4th strand to line;
By " ten " character skeleton that translamella sheet and perpendicular blade are formed, this " ten " character skeleton forms the first, second, third and the 4th cavity by said translamella sheet and perpendicular blade,
Said first strand is positioned at said first cavity to line, and said second strand is positioned at said second cavity to line, and said the 3rd strand is positioned at said the 3rd cavity to line, and said the 4th strand is positioned at said the 4th cavity to line;
The polyester belt coats said first strand line, second strand is twisted line and " ten " character skeleton line, the 4th line, the 3rd strand;
One single face aluminium foil layer coats said polyester belt;
Flame-retardant layer coats said single face aluminium foil layer;
Drain wire is between said polyester belt and single face aluminium foil layer, and this drain wire single face aluminium foil layer therewith conducts connection.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the circle diameter of said " ten " character skeleton is Φ 7.0 ± 0.05mm; The thickness of said translamella sheet and perpendicular blade is 0.7 ± 0.05mm.
2. in the such scheme, said four pair twists are respectively string pitch: 14.7mm, 18.7mm, 11.7mm, 21.7mm.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
The utility model surpasses six types of constructions of cable and has improved input impedance and the crosstalk attenuation that surpasses six types of digital cables; And the increase pitch, thereby reduced the raw material input cost.
