Problems solved by technology
[0003]Different from high-voltage cables, high-voltage connectors are not protected by sheaths, and the shielding part of high-voltage connectors is directly exposed to the environment, and the connection method between high-voltage connectors susceptible to vibration
After long-term vibration wear or chemical corrosion, the electromagnetic shielding effectiveness of high-voltage connectors will decrease significantly, resulting in serious interference of space electromagnetic fields on transmission lines between high-voltage connectors

Description
technical field [0001] Embodiments of the present invention relate to the field of electromagnetic compatibility testing, and in particular, to a device and method for testing the shielding effectiveness of a connector. Background technique [0002] With the development of new energy vehicles in the country, high-voltage connectors for new energy vehicles are a type of connector that is gradually separated from traditional high-voltage high-current and traditional low-voltage automotive connectors. Compared with traditional high-voltage and high-current connectors, the working conditions of high-voltage connectors for new energy vehicles are more complex and changeable, so higher requirements are placed on the shielding efficiency of high-voltage connectors for new energy vehicles. [0003] Unlike high-voltage cables, high-voltage connectors are not protected by a sheath, the shielding portion of high-voltage connectors is directly exposed to the environment, and the connect...
