The invention relates to the technical field of electromagnetic wave information protection, in particular to a flexible foldable electromagnetic shielding box. The box comprises a foldable storage support, a shielding box main body and a waterproof protective sleeve, the shielding box main body comprises a shielding box body and a shielding box cover, the shielding box body and the shielding boxcover are both formed by sewing flexible composite conductive cloth with full-wave-band high-shielding-efficiency through conductive wires, the overlapping design is adopted at the interface overlapping position of the shielding box body and the shielding box cover, magnetic material adsorption and zipper structure locking are utilized, and the waterproof protective sleeve is sewn on the outer layer of the shielding box body and the outer layer of the shielding box cover. The shielding box body and the shielding box cover which are made of the flexible composite conductive cloth with full-wave-band high-shielding-efficiency are sewn and formed through the conductive wires, the manufacturing method is simple, and an upper cover and lower cover extrusion overlapping matching structure is adopted at the interface overlapping position for overlapping, so that a shielding sealing body is effectively formed, and high shielding efficiency is provided.
Description
technical field [0001] The invention relates to the technical field of electromagnetic wave information protection, in particular to a flexible, foldable and portable electromagnetic shielding box. Background technique [0002] Information security cannot be ignored. With the rapid development of the information industry, various electronic devices, large and small, transmit hundreds of millions of important military, political, and economic intelligence and information through the information network all over the world. Information leakage incidents caused by electromagnetic radiation occur from time to time. Studies have shown that the electromagnetic waves radiated by ordinary computers without electromagnetic shielding protection can be received and reproduced one kilometer away. If cutting-edge receiving and decoding equipment is used, the maximum distance intercepted will be even greater. Far. The lightweight and miniaturization of electronic products such as noteboo...
