Description

Technical Field

[0001] The utility model relates to electrostatic discharge test items for electromagnetic compatibility immunity performance testing and conventional electromagnetic compatibility immunity testing, in particular to the technical field of electromagnetic compatibility testing of large-scale on-site equipment and desktop equipment, and specifically to an electromagnetic compatibility mobile grounding plate test vehicle with a liftable vertical coupling plate. Background Art

[0002] When the device is contacted or discharged in the air, the charge attached to the device housing will be discharged again through the holes in the device chassis and between the internal circuit boards or components of the device. Because the impedance of the internal circuit boards or components of the device is small, the harm of secondary discharge may be greater than that of primary discharge. Electrostatic discharge and its impact are a major source of interference for electronic equipment. Due to the existence of static electricity, the human body has almost become the biggest hazard to electronic equipment or explosive materials. Electrostatic discharge often occurs when the human body contacts semiconductor devices, which may cause the semiconductor material to break down and cause irreversible damage. Electrostatic discharge and the resulting electromagnetic field changes may endanger the normal operation of electronic equipment.

[0003] Indirect discharge means discharging the coupling plate. As for the discharge to the horizontal coupling plate, it should be carried out in the horizontal direction to the edge of the horizontal coupling plate, at the front edge of the horizontal coupling plate facing the center point of each unit of the EUT (if applicable) and 0.1m away from the front end of the EUT, at least 10 single discharges should be made with the most sensitive polarity. When discharging, the long axis of the discharge electrode should be in the plane of the horizontal coupling plate and perpendicular to its front edge. The discharge electrode should be in contact with the edge of the horizontal coupling plate. In addition, consider doing this test on all exposed surfaces of the EUT.

[0004] The samples corresponding to conventional immunity tests are divided into desktop and floor-standing types. The desktop test platform needs to be arranged on a 0.8m high insulation support and the surface is covered with a grounding plate with a minimum size of 0.8m*1m. The floor-standing test platform also needs to make the test layout overlap on a grounding plate with a minimum size of 0.8m*1m without any height requirements. The distance between the sample and the equipment is 0.5m or 1m. However, the on-site test customer is generally unable to provide a compliant test platform and grounding plate. If the test party needs to bring their own, it will not only take up transportation space, but also require multiple people to carry the test platform to a suitable layout location after arriving at the site, resulting in the problem of adjusting the vertical coupling plate for different test heights during indirect discharge during on-site testing of large equipment, and the pain point that there is no movable test grounding plate system with a suitable height for on-site testing of desktop and floor-standing equipment.

[0005] Therefore, it is necessary to invent an electromagnetic compatibility mobile grounding plate test vehicle with a liftable vertical coupling plate. Utility Model Content
