GROUNDING INSTRUMENT, STRUCTURE, AND GROUNDING METHOD OF CONDUCTOR HAVING INSULATION LAYER ON SURFACE

摘要

PROBLEM TO BE SOLVED: To perform grounding of an object having an insulation layer such as a coating or insulated plating on the surface.SOLUTION: When a grounding instrument 1 is adsorbed to grounding target 8 by a magnetic force, projections 2 penetrate through an insulation layer 10 and are electrically connected to a conductor 9. Since the projections 2 are electrically connected to a conducting wire 4 and the conducting wire 4 is connected to the ground 7, grounding work is completed only by making the grounding instrument 1 adsorbed to the grounding target 8.
