Description
Technical field
The utility model relates to electromagnetic compatibility shielding technical field, particularly relates to a kind of electromagnetic compatibility shielding case.
Background technology
Traditional electromagnetic compatibility shielding device only uses layer of metal plate to make shielding cavity usually.Due to this relatively simple for structure, therefore can only be applicable to the electromagnetic shielding of low frequency, often not by EMC test.In actual use, easy and other electromagnetic equipments cause electromagnetic interference mutually.Therefore, traditional shielding construction can not meet the shielding requirements under complex electromagnetic environment.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of electromagnetic compatibility shielding case, can possess good electromagnetic compatibility shielding function, be applicable to various shielding electromagnetic waves.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of electromagnetic compatibility shielding case, described electromagnetic compatibility shielding case comprises screening can and is located at the inner casing in described screening can, described screening can comprises glass layer from inside to outside successively, the plastic layer of two-sided plating and the screen be made up of electromagnetic wave absorbent material, described inner casing is made up of aluminium alloy plate, described inner casing and described screening can are spaced from each other, and be connected and fixed by support and described screening can, filled conductive foam between described inner casing and described screening can, described inner casing and described screening can are provided with the shield door that can open and close, and the position of shield door on described inner casing is corresponding with the position of the shield door on described screening can, shield door on described inner casing is made up of aluminium alloy plate, shield door on described screening can is consistent with the structure of described screening can.
Preferably, described electromagnetic compatibility shielding case also comprises refrigerating plant, and described refrigerating plant is positioned at the bottom of described inner casing.
The beneficial effects of the utility model are: the situation being different from prior art, in electromagnetic compatibility shielding case of the present utility model, screening can adopts the structure of composite bed, both the structure of screening can have been strengthened, again can electromagnetic wave absorption effectively, and inner casing can reflection electromagnetic wave, extraneous electromagnetic wave can not be entered, inner electromagnetic wave to external radiation, thus can not can possess good electromagnetic compatibility shielding function, is applicable to various shielding electromagnetic waves.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model electromagnetic compatibility shielding device embodiment.
Fig. 2 is the rip cutting schematic top plan view of the utility model electromagnetic compatibility shielding device 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.
Please also refer to Fig. 1 and Fig. 2.The electromagnetic compatibility shielding case of the present embodiment comprises screening can 1 and the inner casing 2 be located in screening can 1, screening can 1 comprises glass layer 101 from inside to outside successively, the plastic layer 102 of two-sided plating and the screen 103 be made up of electromagnetic wave absorbent material, inner casing 2 is made up of aluminium alloy plate, inner casing 2 and screening can 1 are spaced from each other, and be connected and fixed by support (not indicating in figure) and screening can 1, filled conductive foam 3 between inner casing 2 and screening can 1, inner casing 2 and screening can 1 are provided with the shield door that can open and close, and the position of shield door 21 on inner casing 2 is corresponding with the position of the shield door 11 on screening can 1, shield door 21 on inner casing 2 is made up of aluminium alloy plate, shield door 11 on screening can 1 is consistent with the structure of screening can 1.Shield door 11 is also comprise glass layer 101, the plastic layer 102 of two-sided plating and the screen 103 be made up of electromagnetic wave absorbent material from inside to outside successively.
Wherein, glass layer 101 intensity is high, good springiness, can meet the mechanical requirements such as intensity and anti-impact force needed for screening can 1; The two-sided plating of plastic layer 102, have good electric conductivity, and screen 103 is returned in the reflection of electromagnetic wave that major part can be penetrated screen 103, increases absorption loss, improves shield effectiveness; Screen 103 is owing to adopting electromagnetic wave absorbent material, the electromagnetic wave of the multipath reflection after can being entered by electromagnetic surface reflection, the electromagnetic wave eddy current when internal transmission, inductor loss, electro-magnetic wave absorption loss and electromagnetic wave, the mode attenuate incident of scattering, reaches the effect of electromagnetic shielding.Inner casing 2 adopts aluminium alloy plate, can the electromagnetic wave of reflect ambient.Thus screening can 1 and inner casing 2 reach the effect of dual shield, even if electromagnetic wave is just in case penetrate screening can 1, the all right electromagnetic wave absorption of conducting foam 3, thus the electromagnetic compatibility shielding case of the present embodiment can possess good electromagnetic compatibility shielding function, is applicable to various shielding electromagnetic waves.
In the present embodiment, electromagnetic compatibility shielding case also comprises refrigerating plant 4, and refrigerating plant 4 is positioned at the bottom of inner casing 2.Refrigerating plant 4 is arranged on bottom, can directly to the equipment cooling in inner casing 2.
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.
