The utility model content
The technical problems to be solved in the utility model is to provide a kind of cable that is used for transmission of data signals between computer disk, and this cable has been strengthened effectiveness on the basis of existing technology, has weakened the influence of electromagnetic wave to the computer data signal transmission.
For solving the problems of the technologies described above; the utility model adopts following technical scheme: the computer data transmission cable; comprise exposed earth lead; at least one pair of signal conductor group and be coated on described earth lead and the insulating protective layer of signal conductor group periphery; described signal conductor group comprises the holding wire that complex root is parallel; this every group of signal line group skin all is coated with metal screen layer; described signal conductor and earth lead all be provided with in mode side by side and their central axis in the same plane, the periphery of described metal screen layer is coated with high-density plastic's layer of pasting the absorbing material layer.
Described absorbing material layer is bonded in the inner surface of described high-density plastic's layer.
The thickness of described absorbing material layer is 0.05mm～0.12mm.
The insulation protection laminar surface of described cable has scale marker, for ease of wiring and cutting, the 20 centimetres of settings in the every interval of the scale marker of cable insulating protective layer outer surface.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the beneficial effects of the utility model are: the utility model computer data transmission cable has increased high-density plastic's layer of being pasted with the absorbing material layer, not only can utilize absorbing material to absorb the electromagnetic wave of extraneous radiation, reduce the interference of electromagnetic wave, also can prevent data-signal electromagnetic interference to other electronic instrument in transmittance process simultaneously data; For in high frequency, the hyperfrequency transfer of data, this absorbing material layer has advantages of favorable electromagnetic shielding effect especially; And because the pull resistance of high-density plastic's layer, strengthened the mechanical strength of transmission cable.

Fig. 2 is the cross sectional representation of the utility model data transmission cable.
Embodiment
Further specify embodiment of the present utility model with reference to the accompanying drawings.
With reference to figure 2, the utility model computer data transmission cable comprises a pair of signal conductor group, wherein, each lead group comprises a pair of signal conductor 31,32 that is insulated layer coating respectively and is located at this a pair of exposed earth lead 41,42 to signal conductor 31,32 outsides.The signal conductor 31,32 of this each lead group and the outer surface of earth lead 41,42 coat a metal screen layer 2, and this metal screen layer 2 electrically contacts with each earth lead 41,42.In order to reduce the overall space volume of cable, all signal conductors 31,32, earth lead 41,42 all be arranged side by side and its axis in the same plane, make the flat that is shaped as of cable integral body.And, the periphery of metal screen layer 2 is coated with high-density plastic's layer 5 of pasting absorbing material layer 6, the cable of this structure has dual shield effectiveness, and in the computer data transmission for high frequency, hyperfrequency, this absorbing material layer 6 has advantages of favorable electromagnetic shielding effect especially; And, strengthened the mechanical strength of this transmission cable because the pull resistance of high-density plastic's layer 5 is arranged.The periphery of metal screen layer is that the outermost layer of cable is coated with insulating protective layer 1.
As further improvement, described absorbing material layer 6 is bonded in the inner surface of high-density plastic's layer 5, and thickness the best of this absorbing material layer is 0.05mm～0.12mm.
For convenient in use as required length carry out cutting and budget is reasonably connected up, be provided with scale marker at the outer surface of cable insulating protective layer 1; This scale marker the best is the 20 centimetres of settings in every interval.
In order to make cable have stronger pliability and higher mechanical strength, this cable insulating protective layer 1 is made for high density polyethylene (HDPE).
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
