Summary of the invention
The utility model provides a kind of high-speed data cable with low delay function, this high-speed data cable, on assurance high-speed data cable transmission characteristic basis, can reduce high frequency electromagnetic radiation and capacitive coupling to the impact of data communication and efficiently solve cable end properties center line to delay inequality problem.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-speed data cable with low delay function, comprise: eight copper conductor lines pair that formed by 2 silver coated copper conductors in surface, 2 copper conductors of this copper conductor line centering be arranged in parallel, described copper conductor is the outer insulation foaming layer being covered with as insulation all, if this insulation foaming layer has individual cavity; Six copper conductor lines of described eight copper conductor line centerings are all surrounded with the first polyester belt to outer surface separately, and another two the copper conductor lines of described eight copper conductor line centerings are surrounded with the first one side aluminium foil to outer surface;
One nonwoven fabrics is coated on two copper conductor lines pair that are surrounded with the first one side aluminium foil, and described six copper conductor line strands that are surrounded with the first polyester belt are in described nonwoven fabrics outside;
The second polyester belt is wrapped in six copper conductor lines pair that are positioned at described nonwoven fabrics outside;
The second one side Aluminium Foil Package is overlying on described the second polyester belt outer surface;
The one shielding braid band being formed by tinned copper wire braiding is coated on described the second one side aluminium foil outer surface, and the aluminium foil surface of described the second one side aluminium foil and described shielding braid band electrically contact;
One PVC restrictive coating is coated on described shielding braid band outer surface.
In technique scheme, further improved technical scheme is as follows:
1, in such scheme, if described individual empty volume accounts for 30%～60% of described insulation foaming layer volume.
2,, in such scheme, the count of described shielding braid band is 60%～80%.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model high-speed data cable, has the high-speed data cables of two and single line, and its single line in process of production two parallel extruding of copper conductor forms figure-8 structure line pair, then by strand to, stranding, sheath.Because two single lines of line centering are that parallel extruding forms, strand to time the stretching that is subject to also identical, substantially be two identical lines, so the delay inequality between these two single lines is very little, the delay inequality that ordinary numbers cable test gets off is 10ns/100m, uses its time delay difference of high-speed data cable of two and single line can be controlled at 3ns/100m.
2, the utility model high-speed data cable, its copper conductor is the outer insulation foaming layer being covered with as insulation all, if this insulation foaming layer has individual cavity, can reduce the impact on data communication of high frequency electromagnetic radiation and capacitive coupling, and increased the mechanical strength of cable, thereby increased the service life.
