Abstract
The invention provides an electromagnetic shielding cable. The electromagnetic shielding cable comprises a main cable core, a grounding cable core, an insulating layer, a metal mesh layer and a thin film layer. The insulating layer winds and wraps the main cable core. The metal mesh layer wraps the insulating layer and the grounding cable core. The grounding cable core and the metal mesh layer are at least partially in electric contact. The thin film layer wraps the metal mesh layer. A layer of waterproof insulating paper is bonded to the exterior of the thin film layer. By means of the mode, the electromagnetic interference capacity can be improved.
Description
Technical field
The present invention relates to Power-line technology field, particularly relate to a kind of electromagnetic shielded cable.
Background technology
In radio art, a lot of occasion all needs to use cable transmission signal, but cable, when receiving outside electromagnetic interference, can have an impact to transmitted signal, so must carry out electromagnetic shielding process to cable.Existing cable is generally around insulating barrier and electro-magnetic screen layer on solid conductor, but this cable not only can not shield electromagnetic interference completely, and the electromagnetic interference that always there are some high frequencies penetrates screen, so anti-electromagnetic interference capability is poor.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of electromagnetic shielded cable, can improve electromagnetic interference capability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of electromagnetic shielded cable, described electromagnetic shielded cable comprises master core, ground connection core, insulating barrier, metal net layer and thin layer, described insulating barrier is wrapped outside described master core, described metal net layer is wrapped in outside described insulating barrier and described ground connection core, and described ground connection core and described metal net layer in electrical contact at least partly, described thin layer is coated on described metal net layer, and described thin layer external pasting has one deck waterproof insulation paper.
Preferably, described metal net layer is iron net.
Preferably, described metal net layer is golden net or silver-colored net.
The invention has the beneficial effects as follows: the situation being different from prior art, electromagnetic shielded cable of the present invention by carrying out grounding by ground connection core after wire netting electromagnetic wave absorption, thus can improve electromagnetic interference capability, can realize good electromagnetic interference shielding.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of electromagnetic shielded cable embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the schematic diagram of electromagnetic shielded cable embodiment of the present invention.The electromagnetic shielded cable of the embodiment of the present invention comprises master core 1, ground connection core 2, insulating barrier 3, metal net layer 4 and thin layer 5, insulating barrier 3 is wrapped outside master core 1, metal net layer 4 is wrapped in outside insulating barrier 3 and ground connection core 2, and ground connection core 2 is in electrical contact at least partly with metal net layer 4, thin layer 5 is coated on metal net layer 4, and thin layer 5 external pasting has one deck waterproof insulation paper 6.
Wherein, master core 1 has insulating barrier to wrap up, and ground connection core 2 is directly exposed, and the electromagnetic wave penetrating thin layer 5 is held being directly grounded core 2 with being guided to, thus eliminates electromagnetic impact, improves anti-electromagnetic interference capability.
Alternatively, metal net layer 4 can be iron net, also can be golden net or silver-colored net.Iron net is nonmagnetic metal, can reduce penetrating of low-frequency electromagnetic wave, and golden net or silver-colored net is nonmagnetic metal, can reduce penetrating of frequency electromagnetic waves.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
Claims (3)
