Description

Technical Field

[0001] The utility model relates to the technical field of EMC testing, in particular to an EMC performance testing device. Background Art

[0002] EMC testing comprehensively evaluates the interference level and anti-interference ability of electronic products in the electromagnetic field. This test is one of the most important indicators of product quality, aiming to detect the impact of electromagnetic radiation generated by electrical products on the human body, the public power grid, and other normal working electrical products. The purpose of EMC testing is not only to ensure the performance of the product itself, but also to ensure that the product will not cause adverse effects on the surrounding environment during use, and at the same time, it can resist the interference of the external electromagnetic environment and ensure its stable operation.

[0003] An existing EMC performance testing device with the publication number of CN219369837U includes: a lower box body and an upper box cover. The lower box body is hollow and open at the upper and lower sides. The upper box cover is hollow and open at the lower part. The upper box cover is detachably connected to the upper opening of the lower box body. A bottom plate is arranged at the lower opening of the lower box body; an absorbing material layer is arranged on the inner walls of the lower box body and the upper box cover.

[0004] Although this device adopts an anti-interference rotating table, during the testing process, the interference to the product being tested inside is relatively small, reducing the impact and ensuring the accuracy of the test results.

[0005] However, it is found in actual operation that its EMC testing instrument is fixed in a set position. Therefore, during the detection process, the distance between the EMC testing instrument and the workpiece only changes slightly through the rotation of the anti-interference rotating table, and the position of the EMC testing instrument cannot be adjusted as needed, making it difficult to ensure the accuracy and effectiveness of the test. For this reason, improvements are proposed. Summary of the Utility Model
