Insulation material is formed to surround the stripped power line, and the lower center protrudes downward to expose the stripped power line, and the inner periphery is formed with a fastening tube formed with an inner screw part. A pair of upper and lower sleeve bodies respectively formed;

Semicircular bolts having threaded portions are formed on both ends of which the ends are cut off, and the upper and lower sleeve bodies are secured by fastening nuts by being secured by fastening nuts seated on both sides of the central portion of the upper and lower sleeve bodies and the fixing recesses. A fastening ring for fastening and fastening;

The through hole has an outer thread that is screwed into the inner screw portion of the fastening tube of the upper and lower sleeve body, the end is screwed to contact the power line is peeled off the cover, the conducting hole is inserted in contact with the power line in the center Is formed, there is characterized by having a through-bolt for fastening the lower line by the fixing ring screwed to the outer peripheral edge.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
