<P>PROBLEM TO BE SOLVED: To provide a fitting structure of an underground line high voltage pull-in switch in a supply distribution box capable of easily installing it even in a narrow supply distribution box, with no use of a special fitting tool. <P>SOLUTION: A recess 15 is provided at the upper end of the other side edge 14b, facing each other, of a plate 14 of a switch fitting hardware B. A projection 8 of a fixed length is horizontally provided on the upper part on both sides of a mechanism board 6 of a switch A. The switch fitting hardware B is fixed to an equipment fitting angle 23 in a supply distribution box C. When fitting the switch A to the switch fitting hardware B., each recess 15 on both sides of the switching hardware B is engaged with each projection 8 on both sides of the mechanism board 6 of the switch A for rotatably supporting the switch A. The front bottom of the switch A is pressed toward back side for rotation, with the projection 8 as a rotational axis, so as to be housed in the recess composed of a back board and the plates 14 on both sides of the switch fitting hardware B, thus the switch A is fixed to the switch fitting hardware B. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
