Problems solved by technology
[0003] At present, in the rotating structure, beryllium copper reeds, conductive graphite or a combination of conductive copper balls and conductive graphite are usually used for electromagnetic shielding. However, during long-term use, the beryllium copper reeds wear too much and need to be replaced frequently and easily Lead to electromagnetic shielding failure, and the conductivity of conductive graphite is too low, and the surface of conductive copper balls is easy to oxidize, resulting in low electromagnetic shielding efficiency (generally lower than 80dB)
With the increase of rotation speed, material wear and oxidation will be further aggravated, resulting in accelerated reduction of electromagnetic shielding effectiveness

Description
technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a rotating structure with electromagnetic shielding performance. Background technique [0002] With the rapid development of electronic information technology and the increasingly wide application of various electrical, electronic and information equipment, there are more and more complex electromagnetic fields in the living and activity space of human beings, and the electromagnetic energy is getting bigger and bigger. This will inevitably bring more and more serious electromagnetic pollution to the space environment, and have an increasingly significant impact on human survival, activities and the work of various instruments and equipment. Therefore, how to ensure that the influence of electromagnetic pollution on human health and equipment functions is minimized or even eliminated in the entire or a certain local space environment, and how to achieve electrom...
