Wiring switching board for optical fiber cable

Abstract

Abstract PURPOSE:To decrease the occupying area of supporting plates by using plural sheets of supporting plates which are parallel with each other and are supported freely oscillatably by means of pivot shafts to supporting members at specified intervals and detaining the rotating positions of the respective supporting plates at least at two points by detaining mechanisms. CONSTITUTION:The supporting plate 14 is normally supported in an inclined state by detaining a detaining pin 32 in a lower engaging recess 29. The many supporting plates 14 arranged in a vertical direction are superposed on each other above and below. The pins 32 move into the upper engaging recesses 28 when the supportings are turned upward to a horizontal state successively from the upper positions. The plates 14 slightly move forward and backward with respect to brackets 27 at the time when the pins 32 go into and out of the respective upper and lower recesses 28, 29. The moving quantity thereof is absorbed by the gaps between long holes 31 and the pivot shafts 25. The plates 14 are held horizontal when the pins 32 are engaged into the upper recesses 29. Various operations are carried out in this state. The state of the lower plate 14 can be checked through a through-hole 17 provided before the plate 14 while the plate 14 is in the inclined state.
