Abstract
The utility model discloses a multifunctional coaxial composite cable, the composite cable comprises an aluminum core and two copper leads; the aluminum core is coated with a copper layer, the external surface of the copper layer is coated with an first insulating layer; two copper leads are respectively coated with a second insulating layer, a first aluminum foil layer is coated with two insulating layers; a polyester belt layer is coated with the insulating layer and the first aluminum foil layer, an armor layer is coated on the external surface of the polyester belt layer, a flame retardation layer is coated on the external surface of the armor layer, the armor layer is composed by a galvanizing steel band longitudinally coating on the external surface of the polyester belt layer, and the galvanizing steel band is coated with a polyester film layer. The coaxial composite cable enhances the fatigue resistance and twisting resistance performances of the cable, the service life of the composite cable is prolonged, the coaxial cable and the network cable are integrated in one cable, thereby the clutter of the present cables can be effectively avoided, and the arrangement and maintenance of the cables are convenient.
Description
Technical field
The utility model relates to a kind of coaxial cable, relates in particular to a kind of multifunctional coaxial composite rope.
Background technology
Improving constantly of the fast development of network technology and computing power, user's home terminal type is more and more, and this requirement to the comprehensive wiring system performance is also more and more higher.Network rate improves day by day, means the raising of operating frequency, easier generation electromagnetic radiation and capacitive coupling.Simultaneously, can constantly there be new electromagnetic interference source to produce in the surrounding environment, the radiation of the higher generation of network operating frequency is also more serious, and the equilibrium response of the non-shadow data cable of UTP has been not enough to offset 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 the existing comprehensive wiring system, 4 pairs of ordinary numbers cables of normal operation 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 to 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 impact 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 subject to impact in various degree, and because each cable all is separate unit, throughout the year month after month send out temperature, hot after, cause easily each cable sheath inter-adhesive etc., finally cause broken skin even electric leakage, burning, final initiation fire.
Summary of the invention
The utility model provides a kind of multifunctional coaxial composite rope, and this coaxial composite rope has increased fatigue resistance and the twisting resistance of cable, thereby has prolonged composite rope useful life; Integrated coaxial cable and network cable in the single line cable have avoided existing cable mixed and disorderly effectively, have made things convenient for layout and the maintenance of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multifunctional coaxial composite rope, described composite cable comprise aluminium core and two copper conductors;
Described aluminium core coats a bronze medal layer, and this copper layer outer surface is coated with the first insulating barrier;
Described two copper conductors all are coated with the second insulating barrier separately, and one first aluminium foil layer coats this two insulating barriers;
One polyester belt coats described insulating barrier and the first aluminium foil layer;
One armour is coated on described polyester belt outer surface;
One flame-retardant layer is coated on described armour outer surface.
Further improved technical scheme is as follows in the technique scheme:
1, in the such scheme, described armour is comprised of the vertical galvanized steel strip that is wrapped in described polyester belt outer surface, and this galvanized steel strip is coated with a laminated polyester film.
2. in the such scheme, described copper conductor diameter is 0.5 ± 0.002 mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model multifunctional coaxial composite rope, it has increased fatigue resistance and the twisting resistance of cable, thereby prolonged composite rope useful life, secondly, integrated coaxial cable and network cable in the single line cable have avoided existing cable mixed and disorderly effectively, 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; Again, 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.
