Abstract
The utility model discloses a digital communication cable for connecting indoor electronic equipment such as computers and televisions. The cable comprises a cable core, wherein the cable core is formed by four pairs of core wires with insulating sleeves, and a sheath is arranged outside the cable core. It is characterized in that a shielding sleeve is arranged between the sheath and the cable core. An outer insulating sleeve is arranged between the shielding sleeve and the cable core. The shielding sleeve is an aluminum-plastic composite belt, and the inner layer and the outer layer of the aluminum-plastic composite belt are respectively an aluminum foil and a plastic film. The utility model discloses a digital communication cable can prevent external strong electromagnetic signal's interference, avoids effective signal's distortion.
Description
Technical field
The utility model relates to a kind of cable.Specifically, be indoor electric subsets connection cable for digital communication such as computer, TV.
Background technology
At present, used house cable all is non-shielding five class cables on the electronic equipment such as computer, TV.This cable comprises heart yearn, and this heart yearn is made of four pairs of heart yearns that have insulating sleeve.The outside extrusion molding of cable core has sheath.Because this cable is not taked shielding measure, can't avoid the influence of extraneous signal.When using in the strong-electromagnetic field district, extraneous forceful electric power magnetic signal can be cut in the electromagnetic signal of cable itself and form interference, thereby causes the distortion of useful signal.
Summary of the invention
The purpose of this utility model is to provide a kind of cable for digital communication.This cable for digital communication can prevent the interference of extraneous forceful electric power magnetic signal, avoids the distortion of useful signal.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Cable for digital communication of the present utility model comprises cable core, and this cable core is made of four pairs of heart yearns that have insulating sleeve, and there is sheath its outside.Be characterized between sheath and cable core housing being arranged.Between housing wherein and cable core external insulation sleeve is arranged.Housing is an aluminium-plastic tape, and the inside and outside layer of this aluminium-plastic tape is respectively aluminium foil and plastic film.
Adopt such scheme, have the following advantages:
Because cable for digital communication of the present utility model, between its sheath and cable core housing is arranged, extraneous signal can't enter in the cable, can completely cut off the interference that extraneous strong-electromagnetic field forms the electromagnetic signal of cable own, thereby avoided the distortion of useful signal, guaranteed the normal transmission of electromagnetic signal in the cable.
Description of drawings
Accompanying drawing is a cable for digital communication cross sectional representation of the present utility model.
Embodiment
As shown in drawings, a kind of cable for digital communication of the present utility model is to contain cable core, and this cable core is by four pairs of heart yearns, 5 stranded the forming that have insulating sleeve 4.The outside of cable core has housing 2 and sheath 3 from inside to outside successively.Housing 2 wherein is aluminium-plastic tapes, and the inside and outside layer of this aluminium-plastic tape is respectively aluminium foil and plastic film, its wrapped outside at cable core.Sheath 3 usefulness plastic extruding machines wherein extrude and form.
Another kind of cable for digital communication of the present utility model is to contain cable core, and this cable core is by four pairs of heart yearns, 5 stranded the forming that have insulating sleeve 4.The outside of cable core has external insulation sleeve 1, housing 2 and sheath 3 from inside to outside successively.External insulation sleeve 1 usefulness plastic extruding machine wherein extrudes and forms.Said housing 2 is aluminium-plastic tapes, and the inside and outside layer of this aluminium-plastic tape is respectively aluminium foil and plastic film, its wrapped outside at cable core.Sheath 3 wherein also extrudes with plastic extruding machine and forms.
Claims (4)
