PURPOSE: An optical cable connection box is provided to fix the cover of a box without an extra tool, thereby enhancing work convenience. CONSTITUTION: An optical cable connection box includes a lower box(100), a gasket(200), a tray(300), and a upper box(400). A hinge part(520) is formed on the lower portion inside the knob(500) and fixed to a knob shaft fixing part(120) of the lower box(100). A hook(511) is formed on the upper end of the knob(500) and is hooked to the knob hooking step(410) of the upper box(400). The hinge part(520) forms two shafts side by side and inserts the one of the two into a knob shaft fixing part(120) having a transverse groove shape. The hinge part(520) has an extended part(522). The extended part(522) is formed from the projection of both ends of a first shaft(521) which is fixed by a pin inside a knob body(510). An insertion hole(523) is formed on the end of the extended part(522). A second shaft(524) is inserted into the insertion hole(523) in parallel with the first shaft(521) and fixed. |
