Problems solved by technology
[0004] 1. The existing shielding structure for reducing EMC electromagnetic interference can minimize electromagnetic interference. It is necessary to cover the entire electronic device area with the shielding structure. Usually, two or more parts are used to occupy a large space, resulting in an increase in the volume of the entire device. Increased costs
[0005] 2. Since the metal material with high magnetic permeability has great rigidity and is not easy to deform, the existing shielding structure in the market cannot completely fit the assembled parts after installation, so it cannot maximize the ability to resist EMC electromagnetic interference
[0006] 3. At present, the glue dispensing or sealing ring sealing form of the connector on the market, because the connector is installed and fixed by self-tapping screws, after a long time of work, the self-tapping screws often become loose, resulting in the failure of the seal and causing the failure of the whole vehicle

Description
technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to an integrated anti-electromagnetic signal interference and auxiliary connector sealing structure. Background technique [0002] Sensitive devices such as networks and sensor signal lines are extremely vulnerable to interference; at the same time, they have to face various harsh working conditions, such as rain, snow, wind and sand, potholes on the road surface, and wading through deep water in the desert. Therefore, EMC electromagnetic interference and sealing design are particularly important for new energy vehicles. At present, the protection of EMC electromagnetic interference in the market is generally shielded by metal materials with high magnetic permeability. Because insulation distance, creepage clearance, and installation space must be considered at the same time, The shielding structure and electronic devices are connected by bolts to shield the interf...
