Description
Technical field
The utility model relates to electromagnetic compatibility shielding technical field, particularly relates to a kind of electromagnetic compatibility shielding device.
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.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of electromagnetic compatibility shielding device, 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 device, described electromagnetic compatibility shielding device comprises the screening can be made up of conducting polymer composite and the inner casing be located in described screening can, 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 and shield door is had the ventilating opening of honey comb structure, shield door on described screening can is made up of conducting polymer composite.
Preferably, the diameter of described ventilating opening is less than default electromagnetic wavelength threshold.
Preferably, described electromagnetic compatibility shielding device 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, electromagnetic compatibility shielding device of the present utility model is by adopting shell electromagnetic wave absorption, adopt inner casing reflection electromagnetic wave, extraneous electromagnetic wave can not be entered, inner electromagnetic wave can not to external radiation, thus good electromagnetic compatibility shielding function can be possessed, be 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 device of the present embodiment comprises the screening can 1 be made up of conducting polymer composite and the inner casing 2 be located in screening can 1, 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 and shield door is had the ventilating opening 211 of honey comb structure, shield door 11 on screening can 1 is made up of conducting polymer composite.
Wherein, screening can 1 adopts conducting polymer composite, extraneous electromagnetic wave can be absorbed, inner casing 2 adopts aluminium alloy plate, can the electromagnetic wave of reflect ambient, reaches 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 device of the present embodiment can possess good electromagnetic compatibility shielding function, is applicable to various shielding electromagnetic waves.Further, inner casing 2 can by the ventilating opening 211 on shield door 21 and extraneous ventilation and heat, in addition, can also reflect and absorb the electromagnetic wave passed through, make the electromagnetic wave in inner casing 2 can not to external radiation, electromagnetic wave outside inner casing 2 can not enter in inner casing 2, further enhances electromagnetic compatibility shielding performance.
In the present embodiment, the diameter of ventilating opening 211 is less than default electromagnetic wavelength threshold.In actual applications, the diameter of ventilating opening 211 determines the screening frequencies scope to low-frequency electromagnetic wave, therefore need to shield useless low-frequency interference signal according to the actual requirements, therefore, the diameter designing ventilating opening 211 should be less than the wavelength threshold of the default low-frequency electromagnetic wave that will shield.
Alternatively, electromagnetic compatibility shielding device also comprises refrigerating plant 4, and refrigerating plant 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.
