Abstract:
A power supply shut-off apparatus comprising:an apparatus body including, bus bar mounting portions for respectively mounting one bus bar and another bus bar, a fuse mounting portion for mounting a fuse having one fuse terminal connected to a terminal of the one bus bar and having another fuse terminal connected to a one side edge terminal of an intermediate bus bar, a plug mounting portion which accommodates a terminal holding member in which a terminal of the other bus bar and the other side edge terminal of the intermediate bus bar are disposed on the opposite sides with respect to an insulation wall, and which is formed of a partition wall surrounding an outer periphery of the terminal holding member, and a conduction detecting means mounting portion for mounting conduction detecting means which detects a conduction state in which the one bus bar and the other bus bar are in conduction through the fuse and a nonconduction state therebetween; and a service plug including, a plug housing having a terminal member which is detachably mounted to the plug mounting portion and which is mounted astride the terminal holding member to come contact with the terminal of the other bus bar and to come contact with the terminal of the other side edge of the intermediate bus bar, thereby bringing the one bus bar and the other bus bar into conduction, and a service plug comprising a tilting lever which is tiltable between a substantially vertical state and a substantially horizontal state with respect to the plug housing; wherein when the plug housing is mounted to the plug mounting portion and the tilting lever is tilted down substantially horizontally in a state where the tilting lever of the service plug is held in the substantially vertical state, a projection provided on the tilting lever falls a movable lever of the conduction detecting means so as to allow the conduction detecting means to detect the conduction state between the one bus bar and the other bus bar.
