Claims (1)

[Scope of utility model registration request] An insulating block integrally protruding from a hook for holding an insulated wire at its tip is provided with a vertical hole with a female screw carved along a direction substantially perpendicular to the insulated wire, and is substantially perpendicular to the vertical hole. A metal block with a horizontal hole with a female thread cut in the direction of A blade part provided at the tip of the rod that bites into the insulation coating of the insulated wire and contacts the core wire is exposed from the insulating block and placed opposite the hook, and a screwing jig is provided at the rear end of the metal rod. The connecting portion to be attached and detached is exposed in a recessed hole provided at the rear end of the insulating block, and a recessed groove is formed along the front and back direction on the side surface of the insulating block where the horizontal hole is exposed, and a rear end opening is formed in this recessed groove. A connecting terminal for an insulated wire, characterized in that a connecting wire is inserted into the housing, the connecting end is screwed into a side hole, and an insulating protective cover is removably attached to the insulating block except for the hook. .
