For achieving the above object, the technical scheme that the utility model adopts is: a kind of skeleton structure cable comprises: six roots of sensation copper conductor, 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;
" people " character skeleton of forming by first blade, second blade and the 3rd blade; Said first blade, second blade and the 3rd blade other end separately are equipped with the leaf bud sheet; Said first blade of " people " character skeleton, second blade, the 3rd blade and its corresponding leaf bud sheet form first, second and the 3rd cavity thus;
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;
The polyester belt coats said first strand line, second strand is twisted line and " people " character skeleton line, the 3rd;
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 thickness of said leaf bud sheet is 0.3 ± 0.02mm.
2, in the such scheme, the circle diameter of said " people " character skeleton is Φ 7.0 ± 0.05mm; Said first blade, second blade, three-vaned thickness are 0.7 ± 0.05mm.
3. in the such scheme, said three 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 construction of cable has improved the input impedance and the crosstalk attenuation of digital cable; And the increase pitch, thereby reduced the raw material input cost; Be specially: input impedance (Z0) 1～500MHz:100 ± 12 Ω; Near-end fade performance (20 ℃): >=44.0dB/100m (during 500NHz); 33.8 dB/100m (during 500NHz) far above standard code improve 10.2 dB than standard-required; Far-end fade performance (20 ℃): >=47.7dB/100m (during 500NHz); 13.8 dB/100m (during 500NHz) far above standard code improve 33.9 dB than standard-required.Secondly, production efficiency improves 37.7% than original (original mean pitch is 12.2mm), and twists right comprehensive Haul Rate and reduce by 2% than original (original mean pitch is 12.2mm), and raw material drop into corresponding reduction by 2% like this, also are greatly improved on the cost.Once more, the leaf bud sheet of the utility model can prevent cable in the process of twisting, because the instability of equipment tension force, and individual wire appears to running out of " ten " word cavity, cause properties of product defective.
