Line.
Compared with prior art, the present invention is by the way that the dielectric coefficient for being located at the first clad of inside on the outside of conducting wire to be arranged
For the dielectric coefficient lower than the second clad for being located at outside, the can be so provided by lesser first clad of dielectric coefficient
The preferable signal transmission environment of one conductor, and the external world can be effectively suppressed in when the second clad is using dielectric coefficient higher suction wave layer
Electromagnetic interference effectively completely cuts off the first conductor and the external world, guarantees high frequency, ultra-high frequency signal transmission.
Detailed description of the invention Fig. 1 is the stereoscopic schematic diagram of one preferred embodiment of data transmission cable of the present invention.
Fig. 2 is the cross-sectional view of data transmission cable shown in Fig. 1.
Specific embodiment
A preferred embodiment of data transmission cable 100 of the present invention is shown also referring to Fig. 1 and Fig. 2.The data
Transmission cable 100 includes at least a conducting wire group 1.The conducting wire group 1 includes the first conducting wire 11 and second side by side and being disposed adjacent
Conducting wire 12.First conducting wire 11 and the second conducting wire 12 are Difference signal pair, can be used for transmitting high-frequency signal.
It please refers to shown in Fig. 1 and Fig. 2, first conducting wire 11 and the second conducting wire 12 are respectively provided with positioned at center position
First conductor 13, the first clad 14 for being coated on 13 periphery of the first conductor, the second packet for being coated on 14 periphery of the first clad
Coating 15.In the present invention, the dielectric coefficient of first clad 14 is lower than the dielectric coefficient of the second clad 15.Wherein,
First clad 14 may be configured as dielectric coefficient close to air, so that the impedance of the first clad 14 is smaller, so as to mention
For the preferable signal transmission environment of the first conductor 13, the propagation delay of signal is reduced, reduces the crosstalk between signal, guarantees signal
High speed effectively transmit, reduce signal decaying.In addition, to be set as dielectric coefficient relatively high for second clad 15, specifically
Wave layer is inhaled to be made of the absorbing material by caning absorb electromagnetic wave, thus, it is possible to absorb extraneous radiation using the suction wave layer 15
Electromagnetic wave, effective inhibition outside electromagnetic interference, to the first conductor 13 and it is extraneous effectively completely cut off, guarantee high frequency, hyperfrequency
Signal transmission；In addition, the suction wave layer 15 also has the performances such as light weight, heatproof, moisture-proof, anticorrosive, and then it can effectively protect
The first conductor 13 positioned inside extends the service life of data transmission cable 100 of the present invention.
Further, the data transmission cable 100 further includes the privates 2 for being set to the outside of conducting wire group 1, and described the
