Embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.
A kind of high-frequency signal transmission combination cable, comprise two-way radio frequency cable 7 and two-way power line 6, parcel screen 3 forms radio frequency pair twist group 11 behind described two-way radio frequency cable 7 pair twists, two-way power line 6 wraps up total screen 2 after making the spiral type cable core with radio frequency pair twist group 11 with triangle rock-steady structure coarse pitch strand, has extruded rubber and plastic sheath 1 on described total screen 2.Described radio frequency cable 7 is made of conductor wire core II 9 and the insulating barrier II 8 that extrudes on conductor wire core II 9, and described conductor wire core II 9 forms by zinc-plated circular copper wire is stranded.Described power line 6 is made of conductor wire core I 5 and the insulating barrier I 4 that extrudes on conductor wire core I 5, and described conductor wire core I 5 is formed by the circular copper wire layer-stranding.Described total screen 2, screen 3 form by zinc-plated circular copper wire braiding.
The present invention adopts that 23 0.15mm easily weld, the regular stranded soft bent core of oxidation resistant zinc-plated circular copper wire is as conductor wire core II 9, low with density, thermal resistance is little, organosilane crosslinked polyethylene electric and that mechanical performance is good extrudes thickness 1.1mm insulating barrier 8, makes signal circuit transmission in accordance with regulations.Radio frequency cable 7 is carried out pair twist according to certain pitch form the pair twist group, its impedance operator is stablized remained in the numerical value of regulation, and the impedance decay is stable.On radio frequency pair twist group 11, adopt silver-coated copper wire or the close mesh shields layer 3 that is made into of zinc-plated circular copper wire, form electromagnetic shielding, anti-interference strong, make transmitted signal power unattenuated.Conductor wire core I 5 adopts the 0.20mm circular copper wires to form by the 5+11+16 layer-stranding, makes every lead resistance unanimity, structure tight.Two radio frequency cables 7 adopt coarse pitch limit lining cotton yarn 10 to constitute the cable core that becomes of Stability Analysis of Structures rounding with two power lines 6, becoming to adopt 5 strands on 24 ingots on the cable core, filament diameter is that 0.15 zinc-plated circular copper wire is made into netted total screen 2 according to suitable pitch, improves the shield effectiveness of cable.It is rubber-plastic sheath 1 all over the body that outermost layer adopts collection rubber and pvc material advantage, makes cable both have pliability, the resistance to wear of rubber cable, has the ageing-resistant performance of polyvinyl chloride again.
The foregoing description is preferred embodiment of the present utility model, is not to be used for limiting the utility model practical range, so all equivalent variations of being done with the described content of the utility model claim all should be included within the utility model claim scope.
