Signal transmission cable carry out data transmission between different electronic equipments or between electronic equipment and PC or
The electric energy transmission process such as charge is carried out between different electronic equipments.With epoch progress, the prosperity of the network information causes net
Network information content is increasing, and the demand to transmission speed is also higher and higher, certainly will need the support on hardware.
Pluggable: four-way SFP interface (QSFP) of QSFPQuad Small Form-factor, QSFP are in order to full
Demand of the sufficient market to the pluggable solution of more highdensity high speed and be born.QSFP can be used as a kind of optical fiber solution party
Case, and speed and density are superior to 4 channel C X4 interfaces.Due to can be under the identical port volume of XFP with every channel 10Gbps
Speed support the data transmission in four channels, so the density of QSFP can achieve 4 times of XFP product, the 3 of SFP+ product
Times.It is mainly used for 1. interchangers, router, host adapter bus;2. enterprise stores;3. the I/O of high density, high speed;More than 4.
Channel interconnection etc..QSFP+ high-speed cable is in ten thousand Broadcoms, 10,000,000,000 interchangers, server, supercomputer, cloud computing, Yun Cun
It is used widely in the short distances high speed interconnection such as storage network.How to guarantee that the steady signal transmission of high-speed cable just becomes very heavy
The link wanted.
Summary of the invention
To solve the above-mentioned problems, the transmission cable quickly transmitted can be stablized the present invention provides a kind of.
Technical purpose of the invention is achieved through the following technical solutions:
A kind of high speed data transmission line, including jacket layer, the center of jacket layer successively include two cores from inside to outside
Line conductor, each cored wire conductor are respectively wrapped up by insulating layer, two insulating layers by first layer shield band part wrap up, then again by
Twining package tape integrally wraps up, and the twining package tape shields band package by the second layer again outside, and the second layer shielding is with setting at outer both ends
The ground wire of horizontal direction, the ground wire wrap up the second twining package tape again outside.
It is wrapped preferably, corresponding to first layer shielding outside the twining package tape and the opposite direction of package being provided with second layer shielding band
It wraps up in.
Preferably, the insulating layer is polyolefin or Teflon, two insulating layers are round tangent horizontal position.
Preferably, the first layer shielding band and second layer shielding band are the aluminium foil or copper foil that thickness is less than 0.8mm.
Preferably, the half with a thickness of the second wrapped tape thickness of the twining package tape.
Preferably, the jacket layer is that upper and lower two sides are horizontal, protruded using ground wire as both ends to outside.
Preferably, all ground wire and cored wire conductor are all in same horizontal line.
Beneficial effects of the present invention:
This cable reduces inside and outside interference, ensure that the complete of signal using the design of multiple shielding band and twining package tape
Property, realize high-speed transfer.
Detailed description of the invention
With reference to the accompanying drawing and embodiment the present invention is described in further detail:
Fig. 1 is diagrammatic cross-section of the invention;
Fig. 2 is the enlarged drawing of Fig. 1;
In figure: 1- jacket layer, 2- cored wire conductor, 3- insulating layer, 4- first layer shield band, 5- twining package tape, 6- second layer screen
Shield tape, the second twining package tape of 7-, 8- ground wire.
Specific embodiment
It is as shown in Figs. 1-2:
A kind of high speed data transmission line, including jacket layer 1, the center of jacket layer 1 successively include two from inside to outside
Cored wire conductor 2, each cored wire conductor 2 are respectively wrapped up by insulating layer 3, and two insulating layers 3 are wrapped up by 4 part of first layer shielding band,
Then again by the whole package of twining package tape 5, the twining package tape 5 is wrapped up by second layer shielding band 6 again outside, and the second layer shields band 6
The ground wire 8 of horizontal direction is set at outer both ends, wraps up the second twining package tape 7 again outside the ground wire 8.Corresponding the outside the twining package tape 5
The opposite direction that one layer of shielding band 4 wraps up is provided with second layer shielding band 6 and wraps up.The effect that first layer shields band 4 is a side
It is wrapped to for two insulating layers 3, then carries out second by twining package tape 5 and wrap up, first layer is shielded into band 4 and two
A insulating layer 3 is all bundled together, and the insulating layer 3 is polyolefin or Teflon, and two insulating layers 3 are round tangent level
Position.It is wrapped up again by the opposite direction of the corresponding first layer shielding band 4 of second layer shielding band 6 again, it is wrapped finally by second
It realizes with 7 and is bundled together with the entirety of ground wire 8.All ground wires 8 and cored wire conductor 2 are all in same horizontal line.Finally
Shape to become the jacket layer 1 be that upper and lower two sides are horizontal, be that both ends are protruded to outside with ground wire 8.It both may be implemented in this way
The package of good airproof performance, realization anti-interference function that can also be best.
As preferred effect, first layer shielding band 4 and second layer shielding band 6 be aluminium foil of the thickness less than 0.8mm or
Copper foil.Above-mentioned material all has good ductility and heat conductivity.
The half with a thickness of 7 thickness of the second twining package tape of the twining package tape 5.Primarily to reducing costs, together
When reduce inside line footpath size.
