ABSTRACT:
To assure that electrical connection and disconnection can be achieved without any removal of dark current fuses from a fuse holder, a mechanism for connecting them to and disconnecting them from opponent contact terminals. The mechanism includes a fuse holder having the dark current fuses received therein, a fuse block having the contact members received therein, provisional engaging mechanism serving to hold terminal tabs of each dark current fuse in the electrically disconnected state and firm engaging mechanism serving to hold the terminal tabs in the electrically connected state. The provisional engaging mechanism is constructed of provisional engagement projections on the fuse block and engagement pawls on the fuse holder. The firm engaging mechanism is constructed of firm engagement projections on the fuse block and engagement portions of engagement wall portions on the fuse holder. Alternatively, the provisional engaging mechanism may be constructed of guide projections and engagement projections on the fuse block and cutout grooves and provisional engagement projections on the fuse holder. In this case, firm engagement projections are formed at the position in the vicinity of the terminal ends of the cutout grooves.
