Embodiment
Fig. 1 is the stereogram of an embodiment of electronic installation of the present invention.Fig. 2 is the cutaway view along the A-A line of Fig. 1.Electronic installation is that example is done explanation with a LCD herein, but the present invention is not limited to LCD, and other electronic installations are also applicable.
As shown in Figure 1 and Figure 2, LCD 100 comprises a panel (display module) 10, a housing (earth terminal) 20, a line module 30 and a pliability shade sheet 40.Panel 10 is arranged in the housing 20, line module 30 extends from an end of panel, this line module 30 can be a power line of supplying with tube power, and the bonding side of being located at panel 10 of the part of pliability shade sheet 40, cover the top of line module 30 after remaining part bending, to reach the purpose of blocking electromagnetic interference.The structure of pliability shade sheet below is described.
Please refer to Fig. 3, Fig. 4, Fig. 3 is the stereogram of pliability shade sheet 40, and Fig. 4 is the cutaway view of Fig. 3.Pliability shade sheet 40 comprises an aluminium foil layer (conductive protection layer) 42, one insulating barrier 44 and a conductive layer 46.As shown in Figure 4, one end of insulating barrier 44 is bonded on the aluminium foil layer 42, and remaining part is bent into the ㄇ font, and cover on the aluminium foil layer 42, having on the position that is adjacent to insulating barrier 44 on the aluminium foil layer 42 has a conductive layer 46, it is coated on the aluminium foil layer 42 with conducting resinl and forms, and aluminium foil layer 42 has the effect of covering galvanomagnetic effect.Get back to Fig. 2, the part of aluminium foil layer 42 is attached at a side of panel 10 by conductive layer 46, purpose produces the ground connection effect at the housing 20 that makes the conductive protection layer be connected in the tool conduction property of panel 10 by conducting resinl makes the conductive protection layer have the electromagnetic field screening effect, can certainly stick on the housing 20, can reach the effect of ground connection too.Aluminium foil layer 42 remaining part then with after the suitable length bending, cover on the line module 30 with the state of insulating barrier 44 towards line module 30.Because insulating barrier 44 bends to the ㄇ font, when pliability shade sheet 40 covers line module 30, aluminium foil layer 42 is insulated layer 44 with line module 30 and separates a suitable distance L, so can avoid line module 30 to produce the phenomenon of leakage current on aluminium foil layer 42 and causes working as machine.This distance L is be the bigger the better (insulation effect is good more) basically, considers but often be subject in the housing 20 spaces, and that therefore can only try one's best in limited space goes to strengthen this distance.Because aluminium foil layer 42 is the sides that are bonded in panel 10 with conductive layer 46, can reach the function of ground connection.
Because the height of the ㄇ font of insulating barrier 44 is can be that different demands is made, so aluminium foil layer 42 and distance L between the line module 30 also are different demands and deciding.
Except above-mentioned insulating barrier 44 is bent to the ㄇ font, also can use thicker insulating barrier, smooth in the surface of aluminium foil layer 42, and reach the purpose that makes aluminium foil layer 42 and line module 30 separate a suitable distance L, certainly insulating barrier is being flattened under aluminium foil layer 42 situations, also can use dividing element to be placed between insulating barrier and the line module, can reach above-mentioned purpose equally.
In the present embodiment, insulating barrier 44 is formed by mylar film (Mylar), but is not limited thereto, and also can be that other materials with insulation effect form, for example mica sheet.
The effect of invention
Pliability shade sheet of the present invention utilizes insulating barrier to be incorporated into aluminium foil layer, utilizes the iron plate element to compare with prior art, has advantage with low cost.In addition, because profit is assembled in the method for paste, can save the quantity of using screw.Pliability shade sheet of the present invention is liftable structure, reason line operation that can convenient line module 30.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the accompanying Claim person of defining.
