Claims

[Scope of Claim for Utility Model Registration] A ring contact is fitted into a notch formed in a live part, an insulating member that covers the live part is protruded from around the ring contact in a substantially cylindrical shape to form a mounting part, and the mounting part is mounted. In a voltage detection grounding device that is attached to a part to detect voltage and ground a live part, a removable insulating tube is provided inside the attached part, and when the insulating tube is attached, the outside of the insulating tube protrudes outside the attached part. A voltage detector is attached to the insulating tube, and a voltage detecting terminal that comes into contact with the ring contact when the insulating tube is attached is provided at the tip of the insulating tube and connected to the voltage detector, and a grounding rod that is movable along the axis is installed inside the insulating tube. The tip of the grounding rod is formed to be able to be fitted and removed into a ring contact, and the vicinity of the base end is grounded via a cable, and an insulating handle is provided at the base end, and the outer circumferential surfaces of the grounding rods facing each other are provided. A guide pin is formed on one side of the inner peripheral surface of the insulating cylinder, and a groove for guiding the guide pin is formed on the other side in a substantially L-shape along the axis and the circumferential direction. A spring is provided between the rod and the insulating cylinder to urge the ground rod toward the handle and to rotate the ground rod so that the guide pin moves to the end of the groove extending in the circumferential direction. Characteristic voltage detection grounding device.
