Abstract
The utility model relates to an anti-electromagnetic interference sheet, which comprises a plurality of thin sheets by adhesion. The thin sheets at least include a magnetic metal thin sheet, a non-magnetic metal thin sheet and a polymer thin sheet, the magnetic metal thin sheet can resist low-frequency electromagnetic waves, the non-magnetic metal thin sheet can resist high-frequency electromagnetic waves, and the polymer thin sheet covering the non-magnetic metal thin sheet prevents oxidation of the non-magnetic metal thin sheet. When being mounted inside an electronic product, the anti-electromagnetic interference sheet can reduce mutual interference of electromagnetic waves in the spaces on two sides of the anti-electromagnetic interference sheet.
Description
Technical field
The utility model is a kind of anti-electromagnetic interference sheet, is meant especially to prevent that electromagnetic wave source from disturbing the anti-electromagnetic interference sheet of other electronic building brick.
Background technology
In having the electronic product of sandwich construction, electronic product such as e-book or mobile phone for example, it is mainly by a front end assemblies such as display floater or contact panel, and the control circuit board of aft-end assembly such as an electronic product assembles, when aft-end assembly is worked, it is by voltage and the various signals of current delivery or transmits electric power, but when transmitting signal and transmitting electric power, the change of voltage or electric current all can produce extra electromagnetic wave, no matter be low frequency or frequency electromagnetic waves, when electromagnetic wave that aft-end assembly produced when front end assemblies induces electric charge or electric current, may cause the malfunction of front end assemblies.
The utility model content
The technical problems to be solved in the utility model is: a kind of anti-electromagnetic interference sheet is provided, this anti-electromagnetic interference sheet is arranged between the aft-end assembly and front end assemblies of electronic product, and the electromagnetic wave that aft-end assembly is produced reduces to minimum to the influence that front end assemblies produces.
Technical solution of the present utility model is: a kind of anti-electromagnetic interference sheet is provided, include a magnetic metal thin slice, a nonmagnetic metal thin slice and a polymer flake, this magnetic metal thin slice, this nonmagnetic metal thin slice and this polymer flake bind in regular turn to stick together glue-line.
Aforesaid anti-electromagnetic interference sheet, this magnetic metal thin slice is an iron foil, and this nonmagnetic metal thin slice is an aluminium foil, and this polymer flake is a plastic tab.
Aforesaid anti-electromagnetic interference sheet has one in the described magnetic metal thin slice outside and sticks together glue-line.
Advantage of the present utility model is: by magnetic metal thin slice opposing low-frequency electromagnetic wave, by nonmagnetic metal thin slice opposing frequency electromagnetic waves, to alleviate the influence to front end assemblies of electromagnetic wave that aft-end assembly produced.

Embodiment
Below cooperate preferred embodiment graphic and of the present utility model, further setting forth the utility model is to reach the technological means that predetermined utility model purpose is taked.
Please refer to Fig. 1 and Fig. 2, the designed anti-electromagnetic interference sheet 1 of the utility model is to be sandwich construction, it includes a magnetic metal thin slice 11 at least, an one nonmagnetic metal thin slice 12 and a polymer flake 13, wherein this magnetic metal thin slice 11 is in order to reduce penetrating of low-frequency electromagnetic wave, can be iron foil, cobalt paper tinsel or nickel foil etc. have the sheet metal of magnetic, this nonmagnetic metal thin slice 12 is in order to reduce penetrating of frequency electromagnetic waves, can be goldleaf, silver foil, Copper Foil or aluminium foil etc. do not have the sheet metal of magnetic, if consider production cost of products, it is comparatively appropriate that magnetic metal thin slice 11 uses iron foil and nonmagnetic metal thin slice 12 to use aluminium foil.
This magnetic metal thin slice 11, this nonmagnetic metal thin slice 12 and the mode that this polymer flake 13 combines are to use first and second to stick together glue-line 14,15, and this polymer flake 13, this nonmagnetic metal thin slice 12 are binded in regular turn with this magnetic metal thin slice 11.
In electronic installations such as general e-book or mobile phone, it is as display floater or contact panel by a front end assemblies 3, and one aft-end assembly 2 assemble as the control circuit board of electronic product, and when 2 of rear end groups during in work, the change of its voltage or electric current can produce extra electromagnetic wave, in order to reduce the electromagnetic interference that 2 pairs of front end assemblies 3 of aft-end assembly are produced, the utility model further forms one the 3rd and sticks together glue-line 16 on magnetic metal thin slice 11, stick together glue-line 16 by the 3rd and be attached under the front end assemblies 3.For protecting this nonmagnetic metal thin slice 12; with the aluminium foil is example; aluminium foil is easy to oxidized or is subjected to influence of moisture and reduces the ability of anti-frequency electromagnetic waves; so the function of this polymer flake 13 is isolated nonmagnetic metal thin slices 12 and the contacting of air, wherein polymer flake 13 is with the easiest manufactured use of plastic tab.
Comprehensive the above, the composite wafer structure that the designed anti-electromagnetic interference sheet 1 of the utility model is made up of magnetic metal thin slice 11, nonmagnetic metal thin slice 12 and polymer flake 13, wherein magnetic metal thin slice 11 can be iron foil, this nonmagnetic metal thin slice 12 can be aluminium foil, and this polymer flake 13 can be plastic tab.And when using anti-electromagnetic interference sheet, be magnetic metal thin slice 11 to be seen through the 3rd stick together the bottom surface that glue-line 16 is attached to front end assemblies 3, assemble aft-end assembly 2 and front end assemblies 3 again, then anti-electromagnetic interference sheet between aft-end assembly 2 and front end assemblies 3, and then is reduced the influence of 2 pairs of front end assemblies 3 electromagnetic interference of aft-end assembly by interlayer.
The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement goes out a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
