For realizing above-mentioned purpose, the utility model has adopted following technical proposals:
This high-speed signal transmission lines cable; Include source line group, high-speed signal transmission lines group, insulating barrier and shielding layer structure; Described source line group comprise power line, power line ground shield and be located at power line and the power line ground shield between the power line insulating barrier; Said high-speed signal transmission lines group comprise high-speed signal transmission lines, transmission line screen and be located at high-speed signal transmission lines and the transmission line screen between the transmission line insulating barrier; The high-speed signal transmission lines group is more than two groups, is distributed in the periphery of source line group in the form of a ring, is provided with the transmission cable insulating barrier in the periphery of the high-speed signal transmission lines group that is uniformly distributed with in the form of a ring.
Between the periphery of the high-speed signal transmission lines group that is uniformly distributed with in the form of a ring and transmission cable insulating barrier, be provided with the transmission cable screen.
Be provided with the transmission cable screen in transmission cable insulating barrier periphery.
Described power line ground shield is the braiding webmaster of many metallic conductors compositions or the winding coating layer of metallic conductor.
Coating layer or the braiding webmaster of many metallic conductor compositions or the winding coating layer of metallic conductor that described transmission line screen is formed for the metal foil layer band,
Described power line ground shield, transmission line screen conduct each other.
Described power line ground shield, transmission line screen and transmission cable screen conduct each other.
Be provided with insulation fire prevention filler in the space between source line group, high-speed signal transmission lines group and transmission cable insulating barrier.
Periphery at transmission cable is provided with the transmission cable protective layer.
Periphery at the transmission line screen is provided with the transmission line protection layer.
Through technique scheme, thereby this utility model has following beneficial effect:
1. because in the middle of power line was arranged on, its conductor cross-sectional area can be bigger, thereby can provide than large current load;
Since each root high-speed signal transmission lines with and shielding construction also be coaxial setting, thereby make that this cable antijamming capability amount, data throughout are big, the stable height of transmission performance, the antinoise signal transmission is crosstalked and the common mode signal interference performance is strong, signal transmission quality is high;
3. this power line and HW High Way coaxial-type are arranged, thereby when making, can save more material, and technological process is fast, and efficient is high, and output is big, and qualification rate is high, and production cost is low.
4. this power line and HW High Way coaxial-type structure arranged, total body diameter that can less greatly cable, thus realize ultra-fine ultra gentle requirement.
