Description

Technical Field

[0001] The utility model relates to the technical field of power connectors, in particular to a lightning arrester drainage clamp. Background Art

[0002] The drain wire clamp is a device used to connect the main line and the drain wire (branch line) during the construction, maintenance or modification of power lines. Its main function is to quickly and safely connect the branch line to the main line without cutting the main line, thereby reducing power outage time and improving work efficiency.

[0003] In the prior art, the drainage wire clamp still has some shortcomings when in use: the drainage wire clamp adjusts the tightness of the clamping block through an external bolt to complete the clamping action of the cable. Although the operation is simple, the staff often need to tighten the bolts multiple times during operation, which makes the operation time-consuming, and often requires the use of corresponding tools when tightening the bolts, which makes the operation inconvenient; and the bolts are prone to wear and thread slippage after long-term use, resulting in loosening during use, thereby affecting the tightening effect of the cable, resulting in greatly reduced stability and reliability of the drainage wire clamp.

[0013] Beneficial Effects

[0014] The above one or more technical solutions in the arrester drainage clamp provided by the embodiment of the utility model have at least one of the following technical effects:

[0015] The utility model adopts the above technical scheme, when in use, the rotating shaft is rotated by twisting the torsion block, and the rotating shaft drives the ratchet and the rotating rod to rotate at the same time.
