Ordinary numbers cable: ordinary numbers cable; In order to improve these two electricity function index parameters of input impedance (Z0) and 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.
Summary of the invention
The utility model provides a kind of compound cable of skeleton structure, and this compound cable is multiple cables such as integrated coaxial cable, electric power cable and network cable in the single line cable, thereby have avoided existing cable mixed and disorderly effectively; Improved the input impedance of cable simultaneously, and each line between improved crosstalk attenuation greatly after isolating.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of compound cable of skeleton structure comprises: aluminium core, two first copper conductors and two second copper conductors;
One bronze medal layer coats said aluminium core, and an insulation foaming layer coats said copper layer;
Said two first copper conductors all are coated with first insulating barrier separately, and a single face first aluminium foil layer coats these two first insulating barriers;
Said two second copper conductors all are coated with second insulating barrier separately, and a restrictive coating is overlying on this two second surface of insulating layer outward;
By " people " character skeleton that first blade, second blade and the 3rd blade are formed, this " people " character skeleton forms first, second and the 3rd cavity by said first blade, second blade and the 3rd blade;
Said copper layer is positioned at said first cavity, and said first aluminium foil layer is positioned at said second cavity, and said restrictive coating is positioned at said the 3rd cavity;
The polyester belt coats said insulation foaming layer, first aluminium foil layer, restrictive coating and " people " character skeleton;
One single face, second aluminium foil layer coats said polyester belt;
Flame-retardant layer coats said single face second aluminium foil layer;
Drain wire is between said polyester belt and single face second aluminium foil layer, and this drain wire single face second aluminium foil layer therewith conducts connection.
Related content in the technique scheme is explained as follows:
In the such scheme, the circle diameter of said " people " character skeleton is Φ 7.0 ± 0.05mm; Said first blade, second blade and three-vaned thickness are 0.7 ± 0.05mm.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
The compound cable of the utility model skeleton structure has improved the input impedance and the crosstalk attenuation of digital cable; And the increase pitch, thereby reduced the raw material input cost; Secondly, multiple cables such as integrated coaxial cable, electric power cable and network cable have avoided existing cable mixed and disorderly effectively in the single line cable, and there are defectives such as potential safety hazard in difficult wiring, has made things convenient for the layout and the maintenance of cable, has reduced potential safety hazard; Secondly, adopt the polyester belt that whole cable unit is carried out dampproof effect, fastening whole cable unit, and improve the insulation property of whole cable to the full extent.
