Example Embodiment

[0043] Example one

[0044] Such as Figure 1-3 As shown, in this embodiment, a double-layer moisture-proof electromagnetic shielding box is provided. The double-layer moisture-proof electromagnetic shielding box includes an inner box 1 and an outer box 2, and the inner box 1 is located in the Inside the outer box 2; preferably, a ground terminal is installed at the bottom of the outer box 2. Preferably, the inner casing 1 and the outer casing 2 are welded by galvanized steel plates with a thickness of 2 mm, and the movable parts are equipped with beryllium bronze finger springs to form a complete Faraday cage structure.

[0045] An insulating moisture-proof material 11 is filled between the outer box body 2 and the inner box body 1; preferably, a polyvinyl chloride material is used, which has good moisture resistance and insulation properties. On the premise of ensuring the strength and insulation performance, reasonable layout of insulating materials and reducing the laying are...

Abstract

The invention provides a double-layer moisture-proof electromagnetic shielding box and belongs to the shielding equipment field. The double-layer moisture-proof electromagnetic shielding box comprises an inner-layer box body and an outer-layer box body; a space between the inner-layer box body and the outer-layer box body is filled with a moisture-proof insulating material; the front side and the back side of the outer-layer box body are respectively provided with an upper outer-layer shielding door and a lower outer-layer shielding door; the four outer-layer shielding doors are detachably connected with the outer-layer box body respectively; the two lower outer-layer shielding doors are respectively provided with a plurality of waveguide tubes; the front side wall of the inner-layer box body is provided with an inner-layer shielding door and a plurality of waveguide tubes, wherein the plurality of waveguides tube are located below the inner-layer shielding door; the rear side wall of the inner-layer box body is provided with two inner-layer shielding doors, wherein the lower inner-layer shielding door is provided with a plurality of waveguide tubes; and a plurality of layers of separation boards are arranged in the inner-layer box body. With the double-layer moisture-proof electromagnetic shielding box of the invention adopted, the technical problems of poor moisture-proof effect and poor interior insulation effect of a shielding box in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of shielding equipment, in particular to a double-layer moisture-proof electromagnetic shielding box. Background technique [0002] The waveguide is a hollow metal conduit with a very smooth inner wall or a metal-coated tube; the waveguide is used to transmit ultra-high frequency electromagnetic waves, through which the pulse signal can be transmitted to the destination with minimal loss; the inner diameter of the waveguide The size varies according to the wavelength of the transmitted signal; it is mostly used in radio fields such as centimeter wave and millimeter wave radio communication, radar, and navigation. At present, the common ones are rectangular waveguide, circular waveguide, semicircular waveguide, ku waveguide, radar waveguide and optical waveguide. [0003] The shielding box is a shielding body of various shapes made of conductive or magnetically conductive materials, which limits the electromagnetic ca...
