Interlock structure

Abstract

An interlock structure (1) includes: a conductive case (10) containing an electric device (20); a control unit (40); a conductive lid portion (30); a fastening member (33) for the lid portion (30); a terminal portion (50); a connection wire (51) having one end connected to the terminal portion (50) and the other end connected to the electric device (20); and a detection unit (45) that detects conductivity of the connection wire (51). The case (10) includes an introduction portion (14A, 14B), the connection wire (51) is connected to the terminal portion (50) and the electric device (20) through the introduction portion (14A, 14B), a predetermined voltage is applied between the lid portion (30) and the electric device (20), and the control unit (40) performs control to cut off energization of the electric device (20), when the detection unit (45) detects that the connection wire (51) is in a non-conductive state.
