Description

Technical Field

[0001] This utility model relates to the field of electromagnetic compatibility technology, specifically to an electromagnetic compatibility testing device. Background Technology

[0002] Electromagnetic compatibility (EMC) testing equipment is an analytical instrument that analyzes the ability of a device or system under test to function normally in its electromagnetic environment without causing unacceptable electromagnetic interference to anything in the environment. The installation of wiring devices between the testing equipment and the shielding box occupies a significant amount of space, and the resulting messy wiring on the test bench affects testing efficiency. Furthermore, poor sealing performance of the shielding box leads to inadequate shielding, impacting the accuracy of test data.

[0003] For example, CN202121055621.1 discloses "An EMC Electromagnetic Compatibility Test Device", which sets an electromagnetic sealing gasket at the junction of the shielded box body and the box cover, providing good sealing performance and complete shielding of the tested equipment, thereby improving the accuracy of the test data.

[0004] Electromagnetic sealing gaskets are used to shield and monitor the test equipment. However, no protective cover is added during the test. If test personnel accidentally touch the transmission parts or circuit boards of the equipment, it may cause injury to the human body. This hazard is more serious, especially in laboratory or test environments. Utility Model Content
