Description

Technical Field

[0001] The utility model relates to a network cable grounding device, in particular to a shielding cable grounding clip. Background Art

[0002] At present, industrial enterprises generally use fieldbus control for network communication. Since there are many clutters on the production site, it is very easy to interfere with the bus, so the shielded wire needs to be fixed and grounded. However, the traditional shielded wire fixing clips are of a single size and cannot fix shielded wires of different wire diameters well. In addition, the traditional fixing clips are not firm enough to fix the shielded wires, resulting in poor grounding of the shielded wires, which in turn causes network instability, even network disconnection and production interruption. Once the network communication is interrupted, the troubleshooting and recovery time is long, which greatly affects industrial production. Utility Model Content
