Abstract
A cable used for communication comprises a plurality of twisted signal transmission lines with insulating layers; an aluminum foil layer is arranged at the exterior of each signal transmission line, a metal wire net braided layer is arranged at the exterior of the aluminum foil layer; a protective layer made of a high-molecular polymer is arranged at the exterior of the metal wire net braided layer; a metal conductor is arranged inside each signal transmission line with an insulating layer; the insulating layer is arranged at the exterior of the metal conductor; an aluminum foil layer is arranged at the exterior of the insulating layer; a plurality of signal transmission lines are twisted to form a signal transmission line assembly; and the cable used for communication comprises a plurality of the signal transmission line assemblies. The cable used for communication of the utility model has excellent transmission performance; and with multiple shielding layers, the cable used for communication has strong anti-electromagnetic interference ability as for external interference and mutual interference between the transmission lines.
Description
Technical field
The utility model relates to a kind of communication cable.
Background technology
Progress along with the epoch, internet communication speed is more and more faster, therefore more and more higher with the transmission requirement of cable to the transport of internet signal, the universal indoor and outdoor that causes of household electrical appliance spreads all over various telecommunication cables and power cable, and also can produce interfering with each other of signal between the inner different conductor of the cable of transmission network signal, this has affected transmission accuracy and the rapidity of signal, therefore needs the telecommunication cable of more effective shield electromagnetic interference.
The utility model content
The utility model provides a kind of communication cable of anti-electromagnetic interference, can effectively shield interfering with each other between outer signals and cable inner lead.
The utility model communication cable comprises the signal transmssion line of many stranded tape insulation layers; Be outside equipped with aluminium foil layer at signal transmssion line, aluminium foil layer is outside equipped with the wire screen braid, and the wire screen braid is outside equipped with the protective layer that high molecular polymer is made; The signal transmssion line inside of tape insulation layer is metallic conductor, and metallic conductor arranges insulating barrier outward, and insulating barrier is outside equipped with aluminium foil layer, with many signal transmssion lines stranded be the signal transmssion line group, this communication cable comprises a plurality of signal transmssion line groups.
In this cable, metallic conductor is copper cash.
In this cable, the wire screen braid is the steel wire mesh braid.
The utility model transmission performance is good, due to the existence of multiple shield layer, therefore interfering with each other between external disturbance and transfer wire is had very strong antijamming capability, has well satisfied the requirement to the internet signal transmission, and the signal transmission is undistorted.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
In figure, 1 and 5 be aluminium foil layer, 2 for the wire screen braid, 3 protective layers of making for high molecular polymer; 4 is the high molecular polymer insulating barrier.
As shown in Figure 1, the utility model comprises the signal transmssion line (accompanying drawing only illustrates wherein) of many stranded tape insulation layers; Be outside equipped with aluminium foil layer 1 at signal transmssion line, aluminium foil layer is outside equipped with wire screen braid 2, and the wire screen braid is outside equipped with the protective layer 3 that high molecular polymer is made; The signal transmssion line inside of tape insulation layer is metallic conductor 6, and metallic conductor arranges insulating barrier 4 outward, and insulating barrier is outside equipped with aluminium foil layer 5.
Inner at the utility model cable, be a signal transmssion line group (accompanying drawing is not shown) with stranded group of many signal transmssion lines, this communication cable comprises a plurality of signal transmssion line groups.Thereby this communication cable can transmit many group signals simultaneously.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
