Power shutoff device

A power shutoff device comprising:

• a receiving connector configured to accommodate a pair of main terminals which is installed in a power source circuit;
• a plug connector configured to be fitted into the receiving connector in a fitting direction and to accommodate a conductive member which electrically connects the pair of main terminals;
• an operation lever configured to make the receiving connector and the plug connector fitted or separated;
• and
• a fitting detecting connector configured to detect a fitting state of the receiving connector and the plug connector, wherein
• the operation lever is rotatably and pivotally supported by the plug connector, has leg parts to be connected to the receiving connector, and is provided to be rotatable between a first position where the receiving connector and the plug connector are separated and a second position where the receiving connector and the plug connector are fitted, and to be slidable in a direction perpendicular to the fitting direction at the second position,
• the fitting detecting connector includes a fitting detecting receiving connector which accommodates a pair of fitting detecting terminals in a pipe body penetrating and protruding from a side wall of a housing of the receiving connector, and a fitting detecting plug connector which accommodates a conductive member electrically connecting the pair of fitting detecting terminals in a pipe body, and
• the fitting detecting plug connector is provided at a distal end part of the operation lever so as to be fitted to the fitting detecting receiving connector when the operation lever slides at the second position.
