Abstract
The utility model provides a kind of electromagnetic shielded cable.Electromagnetic shielded cable comprises master core, ground connection core, insulating barrier, metal net layer and thin layer, insulating barrier is wrapped outside master core, metal net layer is wrapped in outside insulating barrier and ground connection core, and ground connection core and metal net layer are in electrical contact at least partly, thin layer is coated on metal net layer, and thin layer external pasting has one deck waterproof insulation paper.By the way, the utility model can improve electromagnetic interference capability.
Description
Technical field
The utility model relates to Power-line technology field, particularly relates 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.
Utility model content
The technical problem that the utility model 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 utility model 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 beneficial effects of the utility model are: the situation being different from prior art, electromagnetic shielded cable of the present utility model is by carrying out grounding by ground connection core after wire netting electromagnetic wave absorption, thus can electromagnetic interference capability be improved, good electromagnetic interference shielding can be realized.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model electromagnetic shielded cable embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1, it is the schematic diagram of the utility model electromagnetic shielded cable embodiment.The electromagnetic shielded cable of the utility model embodiment 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 embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification 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 utility model.
Claims (3)
