Abstract
The utility model discloses an anti-jamming and low-noise communication cable, including conductors, an insulating barrier which covers the conductor and an outer sheath which is in the outermost layer. An antifriction mucilage glue layer is arranged on the outer surface of the insulating barrier. A shielding layer is arranged between the antifriction mucilage glue layer and the outer sheath. The shielding layer is a wire mesh grid and a metallic tin layer is plated on the wire mesh grid symmetrically. In the utility model, the metallic tin can enter and fill all the intervals of the wire mesh grid and condense together with the wire mesh grid. Thus the mesh grid is a metal tube which covers the outer part of the insulating barrier and becomes a protective screen that the outer radio wave can't pass. In this way, the anti-jamming capability of the protective screen is improved a lot and the high quality of transmission of the electronic signal flow is ensured. Besides, the antifriction mucilage glue layer and the protective screen can export the charge of cables out of the system and reduce electrical noise.
Description
Technical field
The utility model relates to a kind of telecommunication cable, relates in particular to a kind of anti-interference low noise telecommunication cable.
Background technology
Existing telecommunication cable conventional structure is to coat insulation material layer, screen and oversheath from inside to outside successively with one heart in the periphery of conductor; Screen wherein adopts many one metal wires at the formed wire netting in cable semi-finished product peripheral braiding back usually; The effect of screen is the radiation that stops extraneous electric wave, the normal conveying of the electronic signal stream in the protection conductor.Because the braiding of wire netting is difficult to accomplish complete densification; Telecommunication cable might bend to various angles when wiring is installed in addition, causes a certain position of wire netting comparatively loose; This just makes that extraneous interference electric wave enters in the cable easily, the communication quality of telecommunication cable is caused disturb and influence.
Summary of the invention
In order to address the above problem, the utility model provides a kind of anti-interference low noise telecommunication cable, can effectively solve a little less than the telecommunication cable antijamming capability and the problem of communication quality difference.
To achieve these goals, the technical solution adopted in the utility model is: a kind of anti-interference low noise telecommunication cable, comprise conductor and be coated on conductor outer insulating barrier and outermost oversheath, described insulating barrier outer surface is covered with the antifriction adhesive-layer, be provided with a screen between described antifriction adhesive-layer and oversheath, this screen is a woven wire cloth, and this metal wire knitted evenly is coated with layer of metal tin on the net.
As preferably, described metallic tin enters and fills up the gap in the woven wire cloth fully.
As preferably, described insulating barrier is made by fluoroplastics.
Advantage of the present utility model is: since metallic tin enter fully fill up in the woven wire cloth the institute gapped, and firmly condense with wire, therefore in fact mesh grid has become " metal cylinder " that is coated on the insulating barrier outside, becomes the barrier that outside electric wave can't be gone beyond; This has just significantly strengthened the antijamming capability of screen, electronic signal stream high quality transmission when having guaranteed communication; In addition, have certain plasticity at the online sheet metal tin of metal wire knitted, do not influence its interference free performance so the telecommunication cable of making still can bend owing to gold-plated.In addition, antifriction adhesive-layer and screen can weaken electrical noise effectively with outside the electric charge derivation system in the cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Referring to Fig. 1, a kind of anti-interference low noise telecommunication cable, comprise conductor 1 and be coated on conductor outer insulating barrier 3 and outermost oversheath 2, described insulating barrier 3 outer surfaces are covered with antifriction adhesive- layer 4,2 of described antifriction adhesive-layer 4 and oversheaths are provided with a screen 5, and this screen 5 is a woven wire cloth, and this metal wire knitted evenly is coated with layer of metal tin on the net, described metallic tin enters and fills up the gap in the woven wire cloth fully, and described insulating barrier 3 is made by fluoroplastics.
The utility model in use because metal wire knitted evenly is coated with layer of metal tin on the net; And insulation material layer adopts fluoroplastics to make.Add man-hour, the cable semi-finished product that coating woven wire cloth passed through the metallic tin of molten condition with certain speed, just were full of fully by metallic tin in the gap of woven wire cloth, and made mesh grid become the stationary housing of a tubular after the cooled and solidified.Because the fluoroplastics that insulation material layer adopts, its fusing point is higher than the metallic tin fusing point, so can not damage insulation material layer when zinc-plated.It is gapped that metallic tin enters the institute of filling up in the woven wire cloth fully, and firmly condense with wire, so in fact woven wire cloth become " metal cylinder " that is coated on insulating barrier 3 outsides, becomes the barrier that outside electric wave can't be gone beyond; This has just significantly strengthened the antijamming capability of screen 5, electronic signal stream high quality transmission when having guaranteed communication; In addition, have certain plasticity at the online sheet metal tin of metal wire knitted, do not influence its interference free performance so the telecommunication cable of making still can bend owing to gold-plated.In addition, antifriction adhesive-layer 4 and screen 5 can weaken electrical noise effectively with outside the electric charge derivation system in the cable.
Claims (3)
