Grounding type elbow connector

A grounding type elbow connector comprising:

• an insulation housing formed of an electrically-insulating material and having a horizontally-symmetric structure in which a cable receiving part extending in a vertical direction crosses a bushing connection part and a voltage detection part extending in a horizontal direction;
• a conductor assembled through the cable receiving part into a center of an internal space between the bushing connection part and the voltage detection part and to which a cable is connected;
• an insulation plug formed of an insulation resin and assembled with the voltage detection part;
• and
• an insulation cap electrically insulating the insulation plug,
• wherein the insulation plug includes:
• an insulation body in which an electrically-conductive stud bolt is insert-formed on a front end of the insulation body and a connecting through-hole is formed inside the insulation body at a rear side of the stud bolt;
• and
• an insulation rod that is detachably fitted into the through-hole,
• wherein a grounding unit having a grounding rod and to which a grounding cable is connected is connected alone, or selectively coupled in a state a grounding inspection connection unit is connected, to the elbow connector after the insulation body is dissembled from the elbow connector.
