Abstract
The utility model relates to an improved cable wire, in particular to a technical proposal on structural improvement for core wire of coaxial cable. The utility model is characterized in that center of the cable core wire is a hollow metal conductor. Diameter of the hollow at the core wire center is 0.5 to 0.7 millimeters. The utility model has extremely obvious beneficial effects. The technical proposal, which will not influence the transmission performance of the signal, can reduce production cost, save copper resources for the state and provide beneficial effects to the consumers.
Description
Technical field
The utility model relates to a kind of improved cable, particularly to the improved technical scheme of core structure in the coaxial wire.
Background technology
At present, rural area, the vast cities and towns of China CATV Project that become basically universal, the transmission of its used signal except that the Shinkansen with the optical cable, branch line almost all adopts the coaxial wire of 75-5,75-7,75-9 and 75-12, this cable national regulation internal core wire specification is 1mm such as the core line diameter of 75-5; 75-7 is 1.25mm; The heart yearn truncation surface diameter of 75-7,75-9 or 75-12 is about 1.5～2.2mm.The transmission of TV signal only by the collection skin transmission of heart yearn, does not have big electric current through heart yearn, and it is not very big that internal resistance is required, and only conductor material and length is had requirement.Therefore, solid copper core cable had not only had to improve but also increased the cost of cable to laser propagation effect, because of the prime cost of cable is on the copper core, we can say that the solid copper core cable of a large amount of uses is a kind of waste of material.
Summary of the invention
The utility model is exactly in order to overcome the defective of prior art, a kind of cable of hollow copper core to be provided.
Technical solution of the present utility model is, cable comprises metallic conductor heart yearn and outer layer insulation protective layer, and the center that it is characterized in that cable core is the hollow metal conductor.
Described outer layer insulation protective layer comprises foam medium layer, tinfoil paper layer, gauze screen and sheath from the inside to the outside; Described cable core is a copper wires.
The hollow diameter at described heart yearn center is 0.5～0.7mm.
The beneficial effects of the utility model are fairly obvious, adopt technical scheme can reach the transmission performance that neither influences signal, can reduce production costs greatly again, for country saves the copper material resource, bring the effect of material benefit for the consumer.
Description of drawings
Fig. 1 is the structural representation of coaxial cable embodiment of the present utility model.
Embodiment
The technical solution of the utility model can be utilized on the high-frequency transmission lead as coaxial cable one class, and that represent in the illustrations is exactly the embodiment that adopts the coaxial cable of the technical program.
Among the figure, 1 is copper core, and 2 is foam medium, and 3 is tinfoil paper, and 4 is gauze screen, and 5 is sheath.
As shown in Figure 1, copper core 1, foam medium 2, tinfoil paper 3, gauze screen 4, sheath 5 once wrap up from inside to outside and constitute cable, and this is the structure of conventional coaxial wire.The technical scheme of taking of the present utility model is to allow copper core 1 should be hollow conductor by conventional solid conductor, and therefore technical characterictic of the present utility model just is this.
The hollow size of copper core 1 is determined according to the heart yearn of different-diameter among the figure, should consider economical with materials, considers the mechanical strength of heart yearn again, guarantees that heart yearn has the performance of the anti-folding of certain tension.
The technical solution of the utility model can be applied in the different high-frequency electrical cables, as long as this cable has the heart yearn of a certain size diameter, realizes that hollow heart yearn can reach the application's technique effect.
The application's embodiment to the further specifying of technical scheme, is not the qualification to the present techniques scheme just, and those skilled in the art can make various changes in the protection range that the application's claim defines.
