GROUNDING DEVICE Russian patent published in 2008 - IPC H01R4/66 

FIELD: electricity.

SUBSTANCE: invention is attributed to electrical energy industry, specifically to grounding devices for movable electric installations intended for maintenance personnel protection against electrical shock. The device comprises metal sharp rod with clamp and two shoulders spaced from each other at distance of hammer stroke where one of the shoulders is located at rod upper part, and hammer for diving with two handles and central vertical hole for moving along the rod. The purpose of the invention is to eliminate the presence of grounding device elements loop joint and design simplification. Stated purpose is achieved due to the fact that in the hammer body throughout its height there is sloping groove with width equal to metal rod diameter and depth up to vertical central plane of hammer, with subsequent groove turning around axis which is perpendicular to vertical central plane of hammer up to coincidence with vertical axis of the hammer.

EFFECT: elimination of loop joint of grounding device elements and design simplification.
