Abstract
The utility model discloses an anti-interference cable. The anti-interference cable comprises conductive cores, a ground wire core, and insulating protection layers which are respectively coated outside the conductive cores and the ground wire core, wherein the conductive cores are uniformly distributed around the ground wire core; a cable core is formed by filling an insulating filler between the conductive cores and the ground wire core; and an insulating layer, a shielding layer and another insulating protection layer are sequentially coated outside the cable core. By using the anti-interference cable as a power transmission circuit of an automatic control system, interference of an external high-frequency electromagnetic wave can be effectively reduced, so that the automatic control system is stabilized, and production can be steadily performed.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of anti-interference cable that is used for the automation control system power supply.
Background technology
Along with science and technology development, industrial automaticity is increasingly high, and the stability of automated production depends on the stability of its control system to a great extent.Because each electric equipment can produce the high frequency clutter when work; These high frequency clutters can interfere with the transmission of electricity circuit of control system, and then influence the stability of control system, though existing input circuit all can be removed clutter through filter; But its effect is still undesirable; Control system still can be disturbed, and causes computer corruption, influences ordinary production.
The utility model content
The purpose of the utility model is that a kind of anti-interference cable will be provided, and this cable can shield the interference of extraneous high frequency clutter.
For achieving the above object; The technical scheme of the utility model is: a kind of anti-interference cable; Comprise conductive cores with the ground core, be wrapped in conductive cores and the outer insulating protective layer of ground core respectively, wire stylet is evenly distributed on around the ground core, between wire stylet and the ground core insulating packing is set; Form cable core, said cable core is wrap insulate layer, screen, insulating protective layer successively outward.
Further, the insulating protective layer outerwrap screen of said conductive cores.
Further, to be that copper strips is overlapping be entwined said screen.
Further, said insulating barrier is that PVC is with overlapping being entwined.
Further, said insulating protective layer is the tubular body that PVC processes.
The outer overlapping winding one deck copper strips of cable core can effectively reduce the interference of extraneous frequency electromagnetic waves as screen, and better shield effectiveness of one deck screen especially is set outside wire stylet.Use the transmission of electricity circuit of this cable, can effectively reduce the interference of extraneous frequency electromagnetic waves, make control system stable, guaranteed stable the carrying out that produces as automation control system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; A kind of anti-interference cable; Comprise conductive cores 1 with ground core 8, be wrapped in conductive cores and the outer insulating protective layer 2,9 of ground core respectively, wire stylet 1 is evenly distributed on around the ground core 8, between wire stylet 1 and the ground core 8 insulating packing 4 is set; Form cable core, said cable core is wrap insulate layer 5, screen 6, insulating protective layer 7 successively outward; In order to reach the better resisting interference effect, the insulating protective layer 2 outerwrap screens 3 of said conductive cores 1; Said screen 3,6 is entwined for copper strips is overlapping; Said insulating barrier 5 is overlapping being entwined for PVC is with; The tubular body that said insulating protective layer 2,7,9 is processed for PVC.
All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into protection scope of the present invention.
