An adapter for an underground distribution line and a ground distribution box is provided to prevent power failure due to abrupt power by releasing the underground distribution line from the ground distribution box only by pushing a knob member up. An adapter for an underground distribution line and a ground distribution box includes a case(100), a connector terminal(200), and an underground distribution line connection member(300). The case includes a guide groove, a receiving groove, and an underground distribution line insertion unit. The underground distribution line connection member includes a first member(330), a moving block(340), a spring(350), a knob member(360), at least two clamps(370), and a snap ring(380). The first member includes a connector terminal connection unit and a spring connection unit. The moving block is inserted into a second passage through the spring to reciprocate vertically and is made of conductive material. The spring is made of conductive material and elastically supports the moving block to be moved to the spring connection unit in one direction. The knob member includes an underground distribution line insertion hole and is fixed to the moving block through the medium of a guide bar moving along the guide groove. At least two clamps are positioned to face each other by including first and second slant surfaces. The snap ring elastically supports the clamps to widen a space between the clamps. |
