Abstract

A kind of high speed data transmission line, including jacket layer, the center of jacket layer successively includes two cored wire conductors from inside to outside, each cored wire conductor is respectively wrapped up by insulating layer, two insulating layers shield band part by first layer and wrap up, and are then integrally wrapped up by twining package tape again, shield band package by the second layer again outside the twining package tape, with the ground wire that horizontal direction is arranged at outer both ends, the ground wire wraps up the second twining package tape again outside for the second layer shielding.This cable reduces inside and outside interference, ensure that the integrality of signal, realize high-speed transfer using the design of multiple shielding band and twining package tape.

Description

A kind of high speed data transmission line

Technical field

The present invention relates to communication Material Fields, specifically provide a kind of high-speed transfer cable for QSFP.

Background technique

Such as mobile phone, digital camera, DV, tablet computer, laptop, personal digital assistant, mobile broadcasting The extensive use of the portable electronic devices such as device in people's lives, people often need to use data line or power supply line etc. 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.
