Abstract
The invention provides an electromagnetic shielding lead wire. The electromagnetic shielding lead wire comprises a main wire core, an ground wire core, an insulation layer, a metal net layer, a fiber layer and an oxidation-resistant film layer, wherein the insulation layer is arranged outside the main in a wrapping layer; the metal net layer is arranged outside the insulation layer and the grounding wire core in the wrapping layer; the grounding wire core is in electric contact with at least one part of the metal net layer; the metal net layer is wrapped by the fiber layer; the fiber layer is wrapped by the oxidation-resistant film layer; the oxidation-resistant film layer is formed by nano-silver in a polymerizing manner. By virtue of the manner, the electromagnetic shielding lead wire can be used for improving the electromagnetic interference performance.
Description
Technical field
The present invention relates to Power-line technology field, particularly relate to a kind of electromagnetic shielding wire.
Background technology
In radio art, a lot of occasion all needs to use wire transmission signal, but cable, when receiving outside electromagnetic interference, can have an impact to transmitted signal, so must carry out electromagnetic shielding process to wire.Existing wire is generally around insulating barrier and electro-magnetic screen layer on single core, but this wire 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 shielding wire, 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 shielding wire, described electromagnetic shielding wire comprises master core, ground connection core, insulating barrier, metal net layer, corpus fibrosum layer and resistance to oxidation rete, 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 corpus fibrosum layer is coated on described metal net layer, described resistance to oxidation rete is coated on described corpus fibrosum layer, described resistance to oxidation rete adopts Nano Silver to be polymerized.
Preferably, described metal net layer is iron net.
The invention has the beneficial effects as follows: the situation being different from prior art, electromagnetic shielding wire 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 shielding wire 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 shielding wire embodiment of the present invention.The electromagnetic shielding wire of the embodiment of the present invention comprises master core 1, ground connection core 2, insulating barrier 3, metal net layer 4, corpus fibrosum layer 5 and resistance to oxidation rete 6, 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, corpus fibrosum layer 5 is coated on metal net layer 4, resistance to oxidation rete 6 is coated on corpus fibrosum layer 5, and resistance to oxidation rete 6 adopts Nano Silver to be polymerized.
Wherein, resistance to oxidation rete 6 of the present invention can make this corpus fibrosum layer 5 have superpower isolation electromagnetic radiation function, and isolating electromagnetic scope control in 1 to 2000MHz band limits, and makes the electromagnetic wave of shielding reach more than 90%.And master core 1 has insulating barrier to wrap up, ground connection core 2 is directly exposed, and the electromagnetic wave penetrating corpus fibrosum 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, and iron net is nonmagnetic metal, can reduce penetrating of low-frequency electromagnetic wave.
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.
