An electric shock preventing apparatus of a switch box for distributing underground wires is provided to enhance stability of the switch box by installing a fuse therein. A plurality of connectors are connected to underground wires and internal wires. A first and second terminals include insertion holes into which connectors of the underground wires and the internal wires are inserted. A housing includes insertion holes for fixing the first and second terminals. A second electrode includes a plurality of grooves which are formed in a longitudinal direction of an inner circumference of a cylinder groove. A filler is implanted into the cylinder groove. A piston is inserted along the cylinder groove and includes a buffering part for absorbing the pressure of the filler and a plurality of protrusions. A first electrode is electrically connected with the first terminal. A fuse(120) is formed with an elastic body for supporting elastically the first electrode. An insulating receptor includes a plurality of through-holes and a guiding groove. A case(130) includes a guide engaged with the guiding groove and a first thread(132) corresponding to a thread(42) in order to be coupled with a pipe(40). |
