Technical Field
[0001] This invention relates to the field of grounding structure technology for electromagnetic shielding materials, specifically to a grounding structure and grounding method for electromagnetic shielding materials. Background Technology
[0002] Today, various electronic devices are increasingly used in people's lives and work. However, these devices generate electromagnetic radiation during operation, which may have adverse effects on people's health. Electromagnetic interference between devices can also cause signal interception, data loss, and other problems, seriously affecting the performance and normal operation of electronic devices. In particular, with the development of the Internet of Things, autonomous driving, and wearable devices, electronic devices are becoming increasingly complex, smaller, and requiring higher precision. To ensure the normal operation of these highly integrated, high-power electronic devices, electromagnetic interference shielding is crucial.
[0003] For example, the authorized patent with publication number CN216566137U (Grounding Structure of Electromagnetic Shielding Material) includes an electromagnetic shielding grounding box and a grounding cable. The inner top wall of the electromagnetic shielding grounding box is provided with a connecting mechanism for protecting and fixing the grounding cable. This grounding structure of the electromagnetic shielding material uses an electromagnetic shielding plate, a bidirectional threaded rod, a driving block, a driving column, a sliding groove, and a stop block in cooperation. Rotating the bidirectional threaded rod causes the driving blocks and driving column on both sides to move in opposite directions, pulling the sliding groove and the electromagnetic shielding plate to rotate around the locking column. This allows the electromagnetic shielding plate to contact the outer surface of the grounding cable, and the upper and lower stop blocks to contact the upper and lower surfaces of the electromagnetic shielding plate, thereby fixing the grounding cable and protecting the part of the grounding cable entering the electromagnetic shielding grounding box. This solves the problem of inconvenient cable protection and fixing.
[0004] The electromagnetic shielding materials mentioned above are not convenient to assemble with the equipment to be shielded, the protection strength is insufficient, and they cannot be used to replace shielding for different equipment, making them inflexible in use. The grounding of the electromagnetic shielding materials is not convenient, and the protection effect of the cables during the grounding process is insufficient. The grounded cables are prone to aging when exposed to air, resulting in a short service life. Summary of the Invention

[0048] A grounding method for electromagnetic shielding materials includes the following steps:
[0049] 1) Bury the grounding electrode 9 into the soil layer below the ground 24, manually pull the connecting frame 4 to swing, and manually adjust the mounting plate 21 to slide in the guide groove 20. Adjust the lateral position of the telescopic sleeve 7 so that it is directly opposite the grounding electrode 9.

The current is then guided into the grounding electrode 9 through the connecting frame 4, the internal cable 25 and the telescopic rod 8, so that the current is conducted into the ground.
[0052] Working principle: When using this equipment, the grounding electrode 9 is buried in the soil layer below the ground surface 24. The connecting frame 4 is manually pulled to swing, and the mounting plate 21 is manually adjusted to slide within the guide groove 20. The lateral position of the telescopic sleeve 7 is adjusted so that it is directly opposite the grounding electrode 9. The telescopic rod 8 is pulled to extend and retract within the telescopic sleeve 7, causing the guide head 26 to slide and guide within the guide cavity 17. One end of the telescopic rod 8 is then connected to the mounting head 18 at the top of the grounding electrode 9. The end of the connecting frame 4 is rotatably connected to the bottom shaft hole of the shielding box 3 via the connecting shaft 22. Connect the internal power connector 23 to the shielding box 3 electrically; place the equipment to be electromagnetically shielded in the electromagnetic shielding groove 14, and manually control the adjustment rod 11 to rotate so that the adjustment rod 11 is driven by the screw in the threaded hole in the middle of the limiting plate 13, so that the adjustment rod 11 controls the clamp 12 to clamp the end of the equipment.
