Abstract
The invention discloses a semi-flexible low loss coaxial radio frequency cable for a mobile base station. The invention is characterized in that: an inner conductor is a copper wire or a copper clad steel wire; and the inner conductor is coated with a composite insulating layer consisting of a first insulating layer and a second insulating layer, a shielding insulating layer, an outer conductor and an outer sheath layer from inside to outside sequentially. The invention has the advantages that expensive gold and silver are saved; the usage of polyfluortetraethylene ten times more expensive than polyethylene is greatly reduced; the cost is obviously reduced; and the cable has good shielding property, high using frequency, low loss, small attenuation and standing-wave ratio and long transmitting distance, can reduce the amount of the base stations in the coverage area and reduce the transmitting cost, and has obvious economic benefit.
Description
Technical field
The present invention relates to a kind of low loss coaxial radio frequency cable, especially inner wire is a copper conductors, and intermediate insulating layer is a composite insulating material, and outer conductor is the coaxial radio frequency cable that metal wire weaves whole wicking, promptly a kind of semi-flexible low loss coaxial radio frequency cable.
Background technology
China is in mobile communication at present, radar, the signal transmission of high frequency such as satellite navigation and electronic countermeasures equipment room, the half flexible coaxial radio frequency cable that uses, its inner wire is made up of silver-copper plated steel clad wire or silver-coated copper wire, with the polytetrafluoroethylene is the intermediate insulation material, with the woven wire of whole wicking as semiflexible outer conductor, its high frequency performance is better, but its weak point is an inner wire will use noble metal silver, in, the price of the insulating material polytetrafluoroethylene of using between outer conductor is a common insulating material more than poly ten times, causes the price of this half flexible coaxial radio frequency cable very expensive.The high frequency of this cable is good in addition, but signal attenuation and standing-wave ratio are big, transmitting range is limited, needs the transmitting base station of laying on the whole many, makes the overall emission expenses of surfing in Internet high.
Summary of the invention
Cost an arm and a leg in order to overcome existing half flexible coaxial radio frequency cable, signal attenuation is big, the deficiency of the limited grade of transmitting range, the invention provides a kind of semi-flexible low loss coaxial radio frequency cable for mobile base station, can constitute composite insulation layer with inexpensive insulating material and minute quantity polytetrafluoroethylene without noble metal silver, make its high-frequency signal attenuation little, loss is low, and transmitting range is far away, and launching costs is economized.
The present invention solves the technical scheme that its technical problem takes: a kind of semi-flexible low loss coaxial radio frequency cable for mobile base station, by inner wire, first insulating barrier, second insulating barrier, shield dielectric layer, outer conductor and external sheath layer are formed, it is characterized in that with the copper conductors being inner wire, coat first insulating barrier from inside to outside successively, second insulating barrier, shield dielectric layer, outer conductor and external sheath layer, inner wire is inexpensive copper conductor or copper covered steel wire, first insulating barrier is that main insulating barrier is made of the polyethylene foamed that contains more air gap, second insulating barrier is by the vertical bag of polytetrafluoroethylene film or wrappedly constitute, combine the formation composite insulation layer with first insulating barrier, its outer one deck insulation screen metal forming that coats, described outer conductor is the tubular shielding conductive layer that the woven wire of half flexible whole wicking forms, and described external sheath layer is by perfluoroethylene-propylene, polyethylene or polyvinyl chloride and so on smoke halogen-free flame-proof plastic for low constitutes.
The invention has the beneficial effects as follows because without noble metal silver, replace expensive polytetrafluoroethylene as insulating material with polyethylene foamed with cheapness, so significantly reduced the cost of this cable, the tubular half flexible outer conductor shielding of the whole wicking of metal wire knitted is good, makes the operating frequency height of cable, standing-wave ratio is little, loss is low, and signal attenuation is little more than 20%, and transmitting range is farther, thereby can reduce the base station number and the construction cost of overlay area, remarkable in economical benefits.
