PROBLEM TO BE SOLVED: To secure high safety in a work to an electric part, with a simple structure.SOLUTION: An interlock device 122 comprises: a storage case 130 for storing electric parts 116, 118; a terminal block 132 which is exposed from an opening part 130a of the storage case, in a state of being stored in the storage case, and which electrically relays the electric parts and an external part; a terminal block cover 134 which is detachably provided on the storage case, and covers the terminal block; a conduction detection part 136 for detecting conduction of the terminal block and the storage case; and an electrification block part 138 for blocking the electrification to the electric parts when conduction of the terminal block and the storage case is not detected. In a state in which the terminal block cover is detached from the storage case, the terminal block and the storage case are insulated, and in a state in which the terminal block cover is attached to the storage case, the terminal block and the storage case are conducted through the terminal block cover.SELECTED DRAWING: Figure 2
【課題】簡易な構成で、電気部品に対する作業時の高い安全性を確保する。【解決手段】インタロック装置122は、電気部品116、118を収容する収容ケース130と、収容ケースに収容された状態で収容ケースの開口部130aから露出し、電気部品と外部とを電気的に中継する端子台132と、収容ケースに着脱自在に設けられ、端子台を覆う端子台カバー134と、端子台と収容ケースとの導通を検出する導通検出部136と、端子台と収容ケースとの導通が検出されないと、電気部品への通電を遮断する通電遮断部138と、を備え、端子台カバーが収容ケースから取り外されている状態では、端子台と収容ケースとが絶縁され、端子台カバーが収容ケースに取り付けられている状態では、端子台カバーを介して、端子台と収容ケースとが導通する。【選択図】図2
