Abstract
A composite cable formed by a network cable and a coaxial cable comprises an aluminum core and two copper wires 0.5 +- 0.002mm in diameter. The aluminum core is wrapped by a copper layer which is wrapped by an insulating foamed layer, each copper wire is wrapped by an insulating layer, and the two copper wires are wrapped by a first single-sided aluminum foil layer. The insulating foamed layer and the insulating layer are wrapped by a polyester strap layer which is wrapped by a second double-sided aluminum foil layer, and the outer surfaces of the aluminum foil layers are wrapped by flame-retardant layers. The composite cable is formed by the network cable and the coaxial cable which are integrated, the defects that existing cables are disordered, have potential safety hazards, and the like can be effectively overcome, and arrangement and maintenance of cables are facilitated.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to the compound cable of a kind of network cable and coaxial cable.
Background technology
The ordinary numbers cable: general data mode transmission numeral cable generally is the transfer wire that adopts electrician's copper cash base to make through technologies such as drawing, annealing, adopts the high-quality polyolefin to coat and forms solid single line; Many solid single lines make up mutually, carry out stranded composition strand to line according to certain lay length of twist; Many strands according to the demand of comprehensive wiring, generally adopt 4～25 pairs of lines to line, carry out total stranded cable of forming into; In the outside that becomes cable, according to actual needs, general indoor cable extrudes one deck PVC polyvinyl chloride at last, and outdoor cable extrudes one deck PE polyethylene.
Along with the high speed development of data communication and information technology, the improving constantly of the fast development of network technology and computing power, user's home terminal type is more and more, and this is also more and more higher to the comprehensive wiring system performance demands.Network rate improves day by day, means the raising of operating frequency, is easy to generate electromagnetic radiation and capacitive coupling more.Simultaneously, can constantly there be new electromagnetic interference source to produce in the surrounding environment, the radiation of the high more generation of network work frequency is also serious more, and the equilibrium response of the non-shadow data cable of UTP has been not enough to offset the electromagnetic radiation and the extraneous electromagnetic interference (Electro Magnetic Compatibility in the time of only satisfying 30～40MHz transfer of data) of express network itself.
In our existing comprehensive wiring system, general use that 4 pairs of ordinary numbers cables are surfed the Net, transfer of data etc., use local cable to advance wiring can to carry out the transmission of phone, voice etc., use common coaxial cable to carry out watching of Web TV, HDTV (High-Definition Television) etc., above cable need influence each other in same pipeline concentric wiring, the phase mutual interference in wiring.
Because the said structure of cable and the limitation of wiring, therefore along with the influence when the high-frequency of electromagnetic radiation and capacitive coupling is more and more outstanding, had a strong impact on the electric property of each cable, cause each cable comprehensive wiring behind the family, the definition of the networking speed of family, telephone relation quality, high definition picture etc. all can be subjected to influence in various degree, and because each cable all is separate unit, throughout the year month after month send out temperature, hot after, cause each cable sheath inter-adhesive etc. easily, finally cause brokenly skin even electric leakage, burning, final initiation fire.
Summary of the invention
The utility model provides the compound cable of a kind of network cable and coaxial cable, this compound cable is integrated coaxial cable and network cable in the single line cable, avoid existing cable mixed and disorderly effectively, had defectives such as potential safety hazard, made things convenient for the layout and the maintenance of cable.
For achieving the above object, the technical solution adopted in the utility model is: the compound cable of a kind of network cable and coaxial cable, described recombination line cable wrap are drawn together aluminium core and two copper conductors;
Described aluminium core coats a bronze medal layer, and this copper layer is coated with the insulation foaming layer;
Described two copper conductors all are coated with insulating barrier separately, and a single face first aluminium foil layer coats this two insulating barriers;
The polyester belt coats described insulation foaming layer and surface of insulating layer;
Second aluminium foil layer coats described polyester belt;
Flame-retardant layer is coated on described aluminium foil layer outer surface.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described second aluminium foil layer is two-sided aluminium foil layer.
2. in the such scheme, described copper conductor diameter is 0.5 ± 0.002 mm.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
The utility model is integrated coaxial cable and network cable in the single line cable, has avoided existing cable mixed and disorderly effectively, 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.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: the compound cable of a kind of network cable and coaxial cable, as shown in Figure 1, described recombination line cable wrap is drawn together aluminium core 1 and two copper conductors 2;
Described aluminium core 1 coats a bronze medal layer 4, and this copper layer 4 is coated with insulation foaming layer 7;
Described two copper conductors 2 all are coated with insulating barrier 5, one single faces first aluminium foil layer 6 separately and coat these two insulating barriers 5;
Second aluminium foil layer 9 coats described polyester belt;
Flame-retardant layer 8 is coated on described aluminium foil layer outer surface, and this flame-retardant layer adopts extra-high-speed flame-proof PVC polyvinyl chloride to make sheath material; The main performance index of this material: oxygen index: 〉=45%; Chemical resistance: acidproof, alkaline-resisting, each kind solvent, various hydraulic pressure wet goods excellent performance.
Above-mentioned second aluminium foil layer 9 is two-sided aluminium foil layer.
Above-mentioned copper conductor 2 diameters are 0.5 ± 0.002 mm.
