Abstract
The utility model discloses an inner conductor of RF coaxial cable for HF and UHF communication, which is composed of multistrand core wires (1) which are twisted. Each stand core wire (1) is divided into three layers; the most inner layer is a steel core wire (2); the middle is a copper cladding (3); the outer layer is a silver coating (4). The utility model collects the high strength of steel, the conductivity of copper and the superhigh conductivity of silver, and has the advantages of discoloration resistance and high temperature resistance. The mechanical property of cables can be enhanced; the use range of cables can be enlarged; the volume of cables can be reduced; the loss and the deduction of communication signals of high-frequency cables can be reduced. The standing wave ratio can be improved, and the quality of communication signals can be enhanced.
Description
Technical field
The utility model relates to the inner wire of a kind of high frequency and hyperfrequency communication usefulness radio frequency coaxial-cable.
Background technology
At present, the inner wire of existing radio frequency cable, coaxial cable is made of silver-coated copper wire, and silver-coated copper wire still can in intermediate frequency, low-frequency range communication, but when high frequency, hyperfrequency communication, because the kelvin effect of high frequency makes the interface of silver-plated copper unclear, forms bigger loss; Silver-coated copper wire intensity is lower in addition, can't use than high-mechanic the time; Bending resistance is bad.
Summary of the invention
The utility model provide a kind of when high frequency, hyperfrequency the communication signal loss minimum, flexility is good, the inner wire of the radio frequency coaxial-cable that tensile strength is high.
The technical solution of the utility model is as follows: a kind of high frequency and the hyperfrequency communication inner wire of radio frequency coaxial-cable, and it is that multiply heart yearn strand is twisted with the fingers composition, and per share heart yearn is divided into three layers, and the innermost layer is the steel heart yearn, and the centre is a copper clad, skin is a silver coating.
In the utility model, inner wire is twisted with the fingers by seven bursts of heart yearn strands and is formed, and silver coating thickness is greater than 1.5 μ m.
After adopting technique scheme, inner wire is twisted with the fingers by multiply heart yearn strand and is formed, when the inner wire diameter is identical, and good bending property, pliability is good.Heart yearn has seven strands, guaranteed the rounding property of cable, per share heart yearn is divided into three layers, and the innermost layer is the steel heart yearn, and the centre is a copper clad, skin is a silver coating, every bed boundary is clear, when high frequency, hyperfrequency communication signal decrease subtract minimum, stable and consistent that can inhibit signal, improve standing-wave ratio, improved signal quality.The steel heart yearn of innermost layer has improved the tensile strength of cable.The utility model inner wire has been gathered the high strength of steel, the conductivity of copper, and the ultra-high conductivity of silver, fastness, high temperature resistant, improved the mechanical performance of cable, enlarged the scope of application of cable, dwindled the cable volume.

Embodiment
With reference to accompanying drawing, the utility model high frequency and the hyperfrequency communication inner wire of radio frequency coaxial-cable, it is that seven strands of heart yearns, 1 strand is twisted with the fingers composition, and per share heart yearn 1 is divided into three layers, and the innermost layer is a black steel heart yearn 2, and the centre is a high-quality copper clad 3, skin is a silver coating 4.Earlier by the steel wire electrolytic treatments, form copper facing during manufacturing in Steel Wire Surface, silver-plated at composite material surface again after handling through cold drawing, form the silver thickness that regulation requires on the surface.The silver-copper plated steel clad blank after the annealing in process, forms the superfine type silver-copper plated steel clad heart yearn of diameter 0.1mm through the multi-pass drawing, at last heart yearn 1 is divided into seven dishes, twist with the fingers through the stranding machine strand, make the inner wire of radio frequency coaxial-cable, wherein silver coating 4 thickness are greater than 1.5 μ m.Conductance of the present utility model is greater than 40%, and tensile strength is greater than 750Mpa.
In the utility model, also can twist with the fingers and form, as long as can keep the rounding property of cable by 19 strands of heart yearns, 32 bursts of heart yearn strands.
Claims (3)
1, a kind of high frequency and hyperfrequency communication is characterized in that with the inner wire of radio frequency coaxial-cable it is that multiply heart yearn (1) strand is twisted with the fingers composition, and per share heart yearn (1) is divided into three layers, and the innermost layer is steel heart yearn (2), and the centre is copper clad (3), and skin is silver coating (4).
2, the inner wire of radio frequency coaxial-cable according to claim 1 is characterized in that it is twisted with the fingers by seven strands of heart yearns (1) strands to form.
