Electromagnetic shielding shell

Abstract

The invention provides an electromagnetic shielding shell which comprises an inner layer, an outer layer and an electromagnetic shielding layer. The electromagnetic shielding layer is sandwiched between the inner layer and the outer layer. The inner layer and the outer layer are made of engineering plastics. The electromagnetic shielding layer is formed by a conductive macromolecule layer. Compared with a traditional metal shell with the function of electromagnetic shielding and composite conductive plastics mixed with metal fibers or metal powder, the electromagnetic shielding shell has the advantages of light weight, simple manufacturing, low cost and electric leakage preventing. Therefore, the electromagnetic shielding shell is suitable for being used on electronic equipment such as a display shell, a machine case shell or a mobile phone shell and the like.

Description

technical field [0001] The invention relates to an electromagnetic shielding shell for electronic and electric equipment. Background technique [0002] With the development of science and technology, human beings have entered the information society, and more and more electronic and electrical equipment are used in production. The electromagnetic energy radiated by electromagnetic waves is increasing at a rate of 7%-14% per year, and the electromagnetic environmental pollution is becoming more and more serious. . On the other hand, the sensitivity of electronic and electrical equipment to the external electromagnetic environment increases, and the electronic and electrical equipment is extremely susceptible to external electromagnetic interference, causing it to malfunction, resulting in serious consequences. Therefore, brand-new electronic equipment and devices with excellent electromagnetic shielding ability have become a problem that the information industry needs to sol...

Problems solved by technology

However, with the miniaturization of electronic and electrical equipment, it is necessary to further reduce the weight of the equipment, and because the density of the conductive filler in the composite conductive plastic is much higher than that of the polymer matrix, it must have at least a certain content to ensure the electromagnetic shielding performance. Therefore, the weight cannot be further reduced, and the cost of the conductive filler cannot be further reduced. In addition, the composite conductive plastic also has the problems of uneven mechanical properties, low mechanical strength, and easy leakage
