Further, according to the mechanism of the fourth aspect, the pair of insulating plates are guided between the pair of contact spring pieces from the insertion space of the female terminal by the lifting operation of the slide board, so that reliable electrical interruption is performed. According to the fifth aspect, since the female terminal is directly separated from the male tab terminal of the dark current fuse by sliding operation of the interrupting member, reliable electrical interruption can be achieved.
