Abstract
The utility model discloses a multifunctional data transmission cable. The multifunctional data transmission cable comprises an aluminium core and two copper conductive wires, wherein the aluminium core is coated by a copper layer, and the copper layer is coated by an insulating foaming layer; the two copper conductive wires are coated with insulating layers respectively, and the two first insulating layers are coated by a first single-sided aluminium foil layer; an isolating plate is located between the first single-sided aluminium foil layer and the insulating foaming layer; the single-sided aluminium foil layer, the insulating foaming layer and the isolating plate are coated by a polyester belt layer; the polyester belt layer is coated by a second single-sided aluminium foil layer; and the second single-sided aluminium foil layer is coated by an outer sheath layer, a drain wire is located between the polyester belt layer and the second single-sided aluminium foil layer, and the drain wire is connected with the second single-sided aluminium foil layer in an electric conduction manner. According to the multifunctional data transmission cable disclosed by the utility model, various wire cables of coaxial cables and network wire cables are integrated in one wire cable, thus effectively avoiding the disorder of the existing wire cables.
Description
Technical field
The utility model relates to a kind of digital cable, relates in particular to a kind of multi-functional data transmission cable.
Background technology
Along with the fast development of network technology and improving constantly of computing power, people are more and more higher to the requirement of comprehensive wiring system performance, requirement to the cable fire grade is also more and more higher, but the competition of each manufacturer is also more and more fierce, how to guarantee that the performance index that farthest improve and improve product seem particularly important under the minimum prerequisite of manufacturing cost.
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 concentricity up to the measures such as fine pith (the average pitch is about 12.2mm) of the single line more than 98%, precision, improve above-mentioned two indexs.But concentricity is not easy to reach in actual production up to the single line more than 98% and accurate fine pith, and normal production qualification rate is very low, and the final products performance also can't guarantee qualification rate in batches; Secondly, existing ordinary numbers cable does not have water resistance, thereby has greatly affected it in outdoor useful life.
Summary of the invention
The utility model provides a kind of multi-functional data transmission cable, and this multi-functional data transmission cable is integrated coaxial cable and the multiple cable of network cable in the single line cable, thereby has effectively avoided existing cable mixed and disorderly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multi-functional data transmission cable comprises aluminium core and two copper conductors; One bronze medal layer coats described aluminium core, and an insulation foaming layer coats described copper layer;
Described two copper conductors all are coated with insulating barrier separately, and a single face the first aluminium foil layer coats this two the first insulating barriers;
One division board is between described single face the first aluminium foil layer and insulation foaming layer;
One polyester belt coats described single face the first aluminium foil layer, insulation foaming layer and division board;
One single face the second aluminium foil layer coats described polyester belt;
External sheath layer coats described single face the second aluminium foil layer.
Related content in the technique scheme is explained as follows:
In the such scheme, a drain wire is between described polyester belt and single face aluminium foil layer, and this drain wire therewith single face aluminium foil layer conducts connection.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model multi-functional data transmission cable, the multiple cables such as integrated coaxial cable and network cable have avoided existing cable mixed and disorderly effectively in the single line cable, difficult wiring, there are the defectives such as potential safety hazard, made things convenient for layout and the maintenance of cable, reduced potential safety hazard; Secondly, adopt the polyester belt that whole cable unit is carried out moistureproof effect, fastening whole cable unit, and improve to the full extent the insulation property of whole cable.
Description of drawings
In the above accompanying drawing: 1, aluminium core; 2, copper conductor; 3, insulating barrier; 4, single face the first aluminium foil layer; 5, insulation foaming layer; 6, drain wire; 7, copper layer; 8, polyester belt; 9, division board; 10, single face the second aluminium foil layer; 11, external sheath layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of multi-functional data transmission cable comprises aluminium core 1 and two copper conductors 2; One bronze medal layer 7 coats described aluminium core 1, one insulation foaming layer 5 and coats described copper layer 4;
Described two copper conductors 2 all are coated with separately insulating barrier 3, one single faces the first aluminium foil layer 4 and coat these two the first insulating barriers 3;
One division board 9 is between described single face the first aluminium foil layer 4 and insulation foaming layer 5;
One polyester belt 8 coats described single face the first aluminium foil layer 4, insulation foaming layer 5 and division board 9;
One single face the second aluminium foil layer 10 coats described polyester belt 8;
One drain wire 6 is between described polyester belt 8 and single face aluminium foil layer 10, and this drain wire 6 therewith single face aluminium foil layer 10 conducts connection.
Adopt above-mentioned multi-functional data transmission cable, it has strengthened cable greatly, and to prevent that moisture, moisture from entering cable inner and affect the ability of serviceability; Secondly, the multiple cables such as integrated coaxial cable and network cable have avoided existing cable mixed and disorderly effectively in the single line cable, and there are the defectives such as potential safety hazard in difficult wiring, has made things convenient for layout and the maintenance of cable, has reduced potential safety hazard; Secondly, adopt the polyester belt that whole cable unit is carried out moistureproof effect, fastening whole cable unit, and improve to the full extent the insulation property of whole cable.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection range of the present utility model.
