GROUNDING CABLE DISTRIBUTION BOARD FOR ELECTRIC SHOCK PROTECTION

摘要

PURPOSE: An insulation structure of an underground distribution box for preventing an electric shock is provided to secure the stability of an underground line connection and facilitate an electric connection operation and a physical connection operation. CONSTITUTION: A connection terminal is connected to the wire of a box(300). A screw thread(211) is formed on the outer side of a coupling terminal(210). A fixing tube(110) has a penetration groove(113) along a longitudinal direction. A stopper is engaged with a protrusion(122) and prevents the separation of a connection tube(120). A spring(140) applies the rotation force to a coupling tube(130) around a connection tube.
