Problems solved by technology

[0003] At present, the frames of electromagnetic shielding cabinets on the market are mostly closed steel structures, the processing is relatively limited, and the internal coating treatment is not easy to carry out. Most of the frames and components are line-surface contact structures, which cannot be effectively carried out by increasing the depth of the gap. Electromagnetic attenuation, the product is not cost-effective

Abstract

The invention discloses an electromagnetic shielding cabinet frame, which comprises a plurality of stand columns, a plurality of cross beams and a plurality of longitudinal beams, wherein the stand columns, the cross beams and the longitudinal beams are connected in a pairwise perpendicular mode to form the frame, and joints of the two ends of each stand column, joints of the two ends of each cross beam and joints of the two ends of each longitudinal beam are bent, embedded and welded to one another; and the joints of the two ends of each stand column, the joints of the two ends of each crossbeam and the joints of the two ends of each longitudinal beam are connected in a full welding mode. The electromagnetic shielding cabinet frame has good continuity and sealing performance, can effectively avoid electromagnetic gap leakage, can guarantee the overall strength and rigidity, safety, stability and anticorrosion protection of the cabinet, has certain compatibility and flexibility, is suitable for an electromagnetic shielding function cabinet, and has the advantages of being simple and reliable in structure, easy to machine, economical in cost and the like.

Description

technical field [0001] The invention relates to the field of electromagnetic shielding, in particular to an electromagnetic shielding cabinet frame. Background technique [0002] It is generally believed that an ideal electromagnetic shield must be a complete and continuous conductor. This is very difficult to achieve, and a completely closed shield has no practical value. In actual application, when different parts of the cabinet shielding body are combined (such as between the frame and the front and rear doors, side panels, and top and bottom panels), there are inevitably gaps in the contact surface, which destroys the continuous conductivity of the shielding cabinet, and also That is, the integrity of the shield, resulting in electromagnetic leakage. [0003] At present, the frames of electromagnetic shielding cabinets on the market are mostly closed steel structures, the processing is relatively limited, and the internal coating treatment is not easy to carry out. Mos...
