Description

Technical Field

[0001] The invention relates to the technical field of wiring clamps, and in particular to a multi-angle grounding clamp structure. Background Art

[0002] Grounding is a technical means to ensure the safety of power operations. By connecting the wire to the earth, it prevents reverse power transmission and induced electricity from harming the safety of workers. All on-site operations involving high-voltage power equipment should be reliably grounded. Due to the high height of large power equipment, on-site workers must use a long insulating rod to send the grounding wire clamp and grounding wire to the live side of the power equipment and lock the grounding clamp before grounding and testing can be achieved.

[0003] Most existing grounding wire clamps are only suitable for clamping horizontal wires, and a small number of right-angle wire clamps can clamp vertical cables or conductors. For the large number of inclined cables or grounding bodies in the distribution network, the existing grounding wire clamps have the following defects due to unreasonable structural design:
