Abstract
The utility model discloses a kind of electromagnetic shielding film; including screen layer; described screen layer includes alloy-layer, is separately positioned on the conductive layer of alloy-layer both sides, insulating barrier, and described conductive layer surface is provided with protecting film layer, and described surface of insulating layer is provided with carrier film layer.This utility model uses said structure, has the advantage that 1, it can effectively block the radiation of the various Eavesdropping conventional frequencies such as radio wave, infrared, ultraviolet.It is thus possible to successfully block electronic eavesdropping, and, it can also bring other benefit to you；2, it is mainly used on the products such as mobile phone, computer screen, palm PC, digital camera；3, electromagnetic wave shield film is possible to prevent or reduces the leakage of electromagnetic signal, prevents the impact of eavesdropping information and electromagnetic interference.
Description
Technical field
This utility model relates to a kind of electromagnetic shielding film.
Background technology
At present, electronic curtain surface is generally sticked protecting film and is protected screen, but electronic product is in the process of use
In often by the electromagnetic interference of adnexa, electronic product function is impacted.Seek to block electromagnetic interference
Technology, is the problem of prior art needs solution.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, it is provided that a kind of electromagnetic shielding film,
To reach to prevent during electronic product uses the purpose of electromagnetic interference.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of electromagnetic shielding film, including screen layer,
Described screen layer includes alloy-layer, is separately positioned on the conductive layer of alloy-layer both sides, insulating barrier, and described conductive layer surface sets
Protected film layer, described surface of insulating layer is provided with carrier film layer.
Described carrying film surface is provided with release film layer.
Described insulating barrier is rubber insulation.
This utility model uses said structure, has the advantage that 1, it can effectively block radio wave, infrared, ultraviolet
Radiation etc. various Eavesdropping conventional frequencies.It is thus possible to successfully block electronic eavesdropping, and, it can also bring other to you
Benefit；2, it is mainly used on the products such as mobile phone, computer screen, palm PC, digital camera；3, electromagnetic wave shield film is possible to prevent
Or the leakage of minimizing electromagnetic signal, prevent the impact of eavesdropping information and electromagnetic interference.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings；
Fig. 1 is lamination layer structure schematic diagram of the present utility model；
In FIG, 2, alloy-layer；3, conductive layer；4, insulating barrier；5, protecting film layer；6, carrier film layer；7, release film layer.
Detailed description of the invention
A kind of electromagnetic shielding film as shown in Figure 1, including screen layer, screen layer includes alloy-layer 2, is separately positioned on alloy-layer
The conductive layer 3 of 2 both sides, insulating barrier 4, insulating barrier 4 is rubber insulation.Described conductive layer 3 surface is provided with protecting film layer 5, institute
Insulating barrier 4 surface stated is provided with carrier film layer 6.
