Technical field:
The present invention relates to the transmission of electronics high-frequency signal, particularly a kind of high-frequency signal transmission wire that is applicable to ultrahigh speed USB 3.0 and preparation method thereof.
Background technology:
The existing designed USB 3.0Cable of standard holding wire is made up of 3P holding wire+power line 2C, its preparation method is to gather with the 1P line after earlier 2P shielded signal wire pair twist being drawn parcel with the aluminium foil wheat again, wrap up with band with power line 2C set back then, braiding, adopt PVC at last, plastics or rubber parcel crust, the sort signal transmission line is owing to adopt normal aluminium foil band parcel, its structural instability, wire rod has bending and moving structure just to be affected slightly, thereby do not reach the transmission quality of high speed signal, because 2P shielded signal wire heart yearn will carry out pair twist, fragile heart yearn during production is difficult to reach the product quality requirement, fraction defective is high, the ability that influence is produced in batches, in addition, because shielded signal wire has only an impurities removal news ground wire, not only caused the holding wire symmetry not good, and can't resist the transmission in the process to shake, it is big to cause common-mode signal to disturb, the high deficiency of transmission error rates.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of Stability Analysis of Structures is provided, antijamming capability is strong, data throughout is big, the stable height of transmission performance, antinoise signal transmission shake and the common mode signal interference performance is strong, halogen-free environmental, electric wire bending and move and do not influence advantages such as data transmission quality, long service life
The present invention can reach by following measure:
A kind of high-frequency signal line, comprise that the 2P shielding is to line, the non-shielding of 1P is to line, two power lines, band, braid and crust, it is characterized in that 2P shielding interrogates ground wires by two heart yearns that are enclosed with insulating barrier with two impurities removals to line and form, 2P shielding is two heart yearns that are enclosed with insulating barrier to the section of line and interrogates ground wires with two impurities removals and lay respectively on the rectangle diagonal, and adopt aluminium foil wheat drawstring and heat to melt PET wheat drawstring parcel, after heating, return fixed structure, so that the 2P shielding is good to the line symmetry, anti-common-mode signal interference performance is strong, the transmission error rates height, structural change is analysed and do not sent out when mobile to 2P shielding to line is curved, thereby guaranteed the biography speed quality of signal, antinoise signal transmission shake interference performance is strong.
A kind of preparation method of high-frequency signal letter is characterized in that step is as follows:
1, earlier respectively to forming the heart yearn that is enclosed with insulating barrier in the holding wire by carrying out back twist with the pair twist rightabout, reducing the dielectric layer structural damage,
2, two after back twist heart yearn and two impurities removal news ground wires that are enclosed with insulating barrier are arranged and pair twist, its section is two heart yearn and two impurities removal news ground wires that are enclosed with insulating barrier and lays respectively on the rectangle diagonal, adopt aluminium foil wheat drawstring parcel, and then, obtain shielding to line, so that the heart yearn dielectric layer is stable with hot fusion method making PET wheat drawstring integument, do not produce and do not wait the series connection medium phenomenon, thereby guaranteed the biography speed quality of signal, antinoise signal transmission shake interference performance is strong
3, two heart yearn pair twists that are enclosed with insulating barrier are made non-shielding to line,
4, with 2P shielding to line, the non-shielding of 1P to line and two power lines to after being twisted into wire harness, wrap up band, braid and crust successively.
The present invention has Stability Analysis of Structures, antijamming capability is strong, data throughout is big, the interference performance of the stable height of transmission performance, antinoise signal transmission shake is strong, halogen-free environmental, electric wire bending and move and do not influence advantages such as data transmission quality, long service life.
