Description
Technical field
The utility model relates to a kind of copper cover aluminum inner wire braided outer conductor radio frequency cable, in particular, relates in particular to the copper cover aluminum inner wire braided outer conductor radio frequency cable that is provided with aluminium matter inner core in a kind of inner wire.
Background technology
Existing Weaving type radio frequency cable all adopts real core fine copper as inner wire, and copper is as good non-ferrous metal conductor, and its manufacturing cost is increasingly high, and each country is all at the consumption that reduces and practice thrift copper as much as possible.Be used for the transmission course of high-frequency signal at radio frequency cable, minimum frequency of operation is also at hundreds of more than million in the practical application; Because kelvin effect, high-frequency signal is concentrated in the transmission of cable top layer, the closer to the conductor center, signal more if.According to Theoretical Calculation; The depth of penetration of the high-frequency signal of practical application on the radio frequency cable center conductor can be above 0.07 millimeter; That is to say real that sub-fraction of having only the top layer that plays transmitting effect on the center conductor; Therefore we can replace the core of whole conductor with other material, reduce the purpose that copper consumption can keep same transmission performance simultaneously again to reach.
Summary of the invention
The utility model provides the copper cover aluminum inner wire braided outer conductor that is provided with aluminium matter inner core in a kind of inner wire radio frequency cable in order to overcome the shortcoming of above-mentioned technical problem.
The copper cover aluminum inner wire braided outer conductor radio frequency cable of the utility model; The cable jacket that comprises inner wire, is arranged at the peripheral insulating barrier of inner wire and plays insulation and protective effect; The insulating barrier outer periphery is equipped with aluminium foil layer, between aluminium foil layer and cable jacket, is provided with braid; Its special feature is: said inner wire is made up of the aluminium matter inner core copper skin peripheral with being arranged at aluminium matter inner core.Insulating barrier is used for producing the vacuum environment of signals transmission, makes the decay of high-frequency signal in transmission course drop to minimum.Aluminium foil layer and braid are formed the outer sleeve body structure jointly, are equivalent to the outer conductor structure; And the form that has been used to adopt aluminium foil layer to match with braid makes whole radio frequency cable have very good pliability, can realize crooked at any angle.Be set to the structure formed by aluminium matter inner core and copper skin through inner wire, can guarantee the normal transmission of high-frequency signal, guaranteed the intensity of inner wire, also practiced thrift the consumption of copper effectively.
The copper cover aluminum inner wire braided outer conductor radio frequency cable of the utility model, said copper outer field thickness is 1.0～2.0mm.Because the kelvin effect of high-frequency signal in transmission course, signal only utilizes the 0.07mm of inner wire skin depth, so copper outer field thickness is set to the requirement that 1.0～2.0mm both can satisfy effectively transmitted signal.
The copper cover aluminum inner wire braided outer conductor radio frequency cable of the utility model, the material of said braid is a tinned wird.Adopt tinned wird as braid, can carry out the transmission of feeder signals with it as outer conductor.
The beneficial effect of the utility model is: the utility model is set to the composite construction be made up of aluminium matter inner core and copper skin through inner wire; Under the situation that has guaranteed effective transmission of high-frequency signal and inner core intensity; Reduce the consumption of copper effectively, practiced thrift raw material.Radio frequency cable in the utility model is compared copper consumption and has been reduced approximately 63% with existing product, entire product weight reduces 30%, and with the current material calculation of price, product cost reduces by 32%.The utlity model has simple for structure, beneficial effect is preferable and be convenient to the advantage of application.

Fig. 2 is the cross-sectional structure sketch map of the radio frequency cable of the utility model;
Fig. 3 is the vertical section structure sketch map of the radio frequency cable of the utility model.
Among the figure: 1 inner wire, 2 insulating barriers, 3 braids, 4 cable jackets, 5 aluminium foil layers, 6 aluminium matter inner cores, 7 copper skins.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, Fig. 2 and shown in Figure 3, provided the structural representation of solid, cross section and the longitudinal section of the utility model, it comprises inner wire 1, insulating barrier 2, braid 3, cable jacket 4, aluminium foil layer 5; Insulating barrier 2 is arranged at the periphery of inner wire 1, and aluminium foil layer 5 is arranged at the outside of insulating barrier 2, and aluminium foil layer 5 is realized the shielding action of high-frequency signal.Braid 3 is arranged at the periphery of aluminium foil layer, and braid 3 has been formed outer conductor jointly with aluminium foil layer, realizes signal shielding and feeder line effect.Cable jacket 4 is arranged at the periphery of braid 3, has insulation and protective effect.Be positioned at the aluminium matter inner core 6 at center and be arranged at copper outer 7 of aluminium matter inner core 6 peripheries and formed inner wire 1 jointly; Because the kelvin effect of high-frequency signal in transmission course; High-frequency signal transmits on copper outer 7; Be positioned at the intensity that inner aluminium matter inner core has not only effectively guaranteed inner wire 1, also effectively reduced the consumption of copper, meet the strategic requirement that country utilizes about non-ferrous metal.
Wherein, copper outer 7 thickness can be chosen between 1.0～2.0mm, all the requirement of satisfiability ability; Copper outer 7 thickness is preferably 0.12mm.Braid 3 adopts tinned wird to have good outer conductor effect.The utility model is in the process of making; Aluminium matter inner core 6 can adopt the technology of no seam welding and drawing that two kinds of materials are combined with copper outer 7; Form complete inner wire structure, the insulating barrier 2, aluminium foil layer 5, braid 3, the cable jacket that constitute with foam insulating material then constitute complete cable together.
The design and traditional design are thought comparison, and on the basis of same transmission performance, the inner wire copper consumption has only 37% of traditional design, greatly reduces cost.Press the actual product test result analysis, it is about 63% that new design centre conductive copper consumption has reduced, and entire product weight reduces 30%, and with the current material calculation of price, product cost reduces by 32%.
