AI Technical Summary
During the grounding process of cable terminals, the connection points are easily contaminated, resulting in poor grounding stability. Furthermore, the hanging structure is prone to shaking and detachment, posing a safety hazard.
The system employs a circular array of hooks and pivots on the grounding ring plate. The hooks are inserted deep into the ground to create a retraction limit. Combined with the clamping isolation of the top and bottom covers and the elastic connection of the spring wires, the system ensures that the wiring hooks always have a downward pulling force, achieving stable embedding into the ground and a tight connection.
It improves the stability and pollution resistance of the grounding device, prevents the connection points from shaking and coming loose, and ensures the reliability and safety of the grounding.
