Abstract

The invention relates to a symmetric transmission line for transmitting a high-frequency signal. The symmetric transmission line comprises two insulation wires, wherein the two insulation wires are arranged in parallel, each insulation wire comprises a Kevlar fiber reinforced plastics (KFRP) aramid fiber rod, a spiral copper wire is wound around the KFRP aramid fiber rod, and a high-density polyethylene (HDPE) insulation layer is further arranged on the KFRP aramid fiber rod. By winding the spiral copper wire around the KFRP aramid fiber rod, the inductance of the copper wire is increased, the capacitance formed between the two insulation wires are offset, the characteristic impedance of the whole transmission line shows resistance, the attenuation and signal distortion of the transmission line are reduced, and the transmission frequency and the transmission distance of the transmission line are increased.

Description

A kind of balanced pair of transmitting high-frequency signal
Technical field
The present invention relates to field of signal transmissions, refer in particular to a kind of balanced pair of transmitting high-frequency signal.
Background technology
The transmission of high frequency electrical signal generally adopts bimetallic transmission line, and bimetallic transmission line is divided into balanced pair and the large class of asymmetric transmission line two, and this two large class transmission line is due to two parallel placements of metallic conductor, make form very large electric capacity between two metallic conductors, thus make the characteristic impedance of whole transmission line be capacitive character, energy attenuation when causing high-frequency signal to transmit, cause efficiency of transmission not high, and the time domain waveform of signal transmission can be made to produce distortion or produce serious intersymbol interference when transmission of high-rate digital signal in capacitive transmission line, seriously limit the bandwidth of signal transmission, for this reason, we have developed a kind of balanced pair of transmitting high-frequency signal, by every root metallic conductor spiral being placed the inductance value increased on copper conductor, offset the capacitance formed between two metallic conductors, the characteristic impedance of whole transmission line is made to be resistive, thus reduce decay and the distorted signals of transmission line, add transmission frequency and the transmission range of transmission line.
Summary of the invention
The present invention seeks to provide a kind of make the characteristic impedance of whole transmission line be the balanced pair of ohmic transmitting high-frequency signal to overcome the deficiencies in the prior art, thus reduce decay and the distorted signals of transmission line, add transmission frequency and the transmission range of transmission line.
For achieving the above object, the technical solution used in the present invention is: a kind of balanced pair of transmitting high-frequency signal, comprises the insulated conductor of two parallel placements; Insulated conductor described in every root comprises KFRP aramid fiber rod; Described KFRP aramid fiber rod is wound with spiral copper conductor, and described KFRP aramid fiber rod is also provided with one deck HDPE insulating barrier.
Preferably, two described insulated conductors are by adhesion or to be strandedly connected.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The balanced pair of transmitting high-frequency signal of the present invention by being wound with spiral copper conductor on KFRP aramid fiber rod, add the inductance value on copper conductor, thus counteract the capacitance formed between two insulated electric conductors, the characteristic impedance of whole transmission line is made to be resistive, thus reduce decay and the distorted signals of transmission line, add transmission frequency and the transmission range of transmission line, and add flexibility and the stability of whole transmission line.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structure chart of the balanced pair of transmitting high-frequency signal of the present invention;
Accompanying drawing 2 is the sectional drawing of the balanced pair of transmitting high-frequency signal of the present invention.
Wherein: 1, KFRP aramid fiber rod; 2, copper conductor; 3, HDPE insulating barrier.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1-2 is the balanced pair of transmitting high-frequency signal of the present invention, comprises the insulated conductor of two parallel placements; Two described insulated conductors are by adhesion or be strandedly connected, and described in every root, insulated conductor comprises KFRP aramid fiber rod 1; Described KFRP aramid fiber rod 1 is wound with spiral copper conductor 2, be used for increasing the inductance value on copper conductor 2, offset the capacitance formed between two insulated electric conductors, thus make the characteristic impedance of whole transmission line be resistive, and KFRP aramid fiber rod 1 has good flexibility and stability, thus add flexibility and the stability of whole transmission line; Described KFRP aramid fiber rod 1 is also provided with one deck HDPE insulating barrier 3, plays insulating effect, and the dielectric loss of HDPE insulating barrier 3 pairs of high-frequency signals absorbs little.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The balanced pair of transmitting high-frequency signal of the present invention by being wound with spiral copper conductor on KFRP aramid fiber rod, add the inductance value on copper conductor, thus counteract the capacitance formed between two insulated electric conductors, the characteristic impedance of whole transmission line is made to be resistive, thus reduce decay and the distorted signals of transmission line, add transmission frequency and the transmission range of transmission line, and add flexibility and the stability of whole transmission line.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
