Once the electromagnetic wave frequency is higher than 100 kHz, the electromagnetic wave can propagate in the air and be reflected by the ionosphere on the outer edge of the atmosphere, forming a long-distance transmission ability. We call the high-frequency electromagnetic wave with long-distance transmission ability radio frequency. In order to enable an electronic device to have a unified reference potential during operation, avoid the interference of harmful electromagnetic fields, and enable the electronic device to work stably and reliably, the signal circuit in the electronic device should be grounded, and a grounding device is required to ground the radio frequency signal.

[0026] Working principle: When actually grounding the signal, according to the parallel single-point signal grounding (the advantage of parallel single-point signal grounding is that there is no common impedance coupling), select the corresponding grounding conductor 7 according to the number of ground wires ( Figure 3 In the middle, there are three threaded holes 14 in the grounding conductor 7, corresponding to three groups of ground wires that can be connected). Then, install the grounding conductor 7 through the connecting component 2. The specific method is to pull the pull ring 204 outwards. The outward movement of the pull ring 204 drives the connecting rod 205 to move outwards. The outward movement of the connecting rod 205 drives the circular plate 207 to move outwards. The outward movement of the circular plate 207 compresses the spring 206. The outward movement of the circular plate 207 drives the pull rod 208 to move outwards. The outward movement of the pull rod 208 drives the insertion block 209 to move outwards. The outward movement of the insertion block 209 retracts into the upper grounding post 1. Then, align the lower end of the grounding conductor 7 with the slot 9 of the upper grounding post 1 and insert it. Release the pull ring 204. Under the rebound effect of the spring 206, drive the insertion block 209 to insert into the insertion hole 15 to complete the installation. Through the setting of the connecting component 2, the movable connection between the grounding conductor 7 and the upper grounding post 1 is realized, so as to conveniently install the appropriate grounding conductor 7 flexibly according to the number of ground wires, improve the practicability of the device, and compared with the connection of the bolt 12, the connection speed is faster. When the ground wires need to be rearranged later, the disassembly speed of the grounding conductor 7 is faster;

[0027] Subsequently, the connecting ring 10 and the grounding conductor 7 are connected by bolts 12, and the equipment connected to another set of connecting rings 10 is connected. Subsequently, the whole device is buried in the soil body (to avoid direct connection with the large-power power ground and digital ground). Among them, the lower grounding post 4 is at the lower part. The purpose of signal grounding is to provide a stable reference potential for the signal. When the number of signal ground wires changes in the later stage, the grounding conductor 7 is taken out through the connecting component 2, the fixing of the connecting ring 10 by the bolt 12 is released, and a suitable grounding conductor 7 is reinstalled for re-grounding.
