<P>PROBLEM TO BE SOLVED: To allow easy confirmation about whether an optical connector plug at the time of fitting is in an incompletely inserted state or a normally inserted state and to prevent another optical connector plug from being inserted from the opposite side of an optical connector adapter when a shutter is not completely opened. <P>SOLUTION: A first projection 51 for positioning is provided at a rear end part of an outer cover 24, and a second projection 52 for positioning is provided at a rear end part of a knob 12 so as to correspond to the first projection 51. Both of the projections 51 and 52 are formed so as to overlap with each other in a state where an optical plug P is normally fitted to an adapter Q, at a movement end where the outer cover 24 is moved backward up to a position of a stopper guide 22 in a rear part together with a spring guide 23, and an incomplete insertion prevention cap 53 is provided which can be fitted over the first projection 51 and the second projection 52 in order to maintain the overlap of both of the projections 51 and 52. <P>COPYRIGHT: (C)2013,JPO&INPIT |
