<P>PROBLEM TO BE SOLVED: To prevent a mis-detection even when electric leak occurs in a connection member disconnection detection apparatus. <P>SOLUTION: A connection member disconnection detection apparatus 1 detects whether a safety plug 15 (connection member) is disconnected or not. The safety plug 15 is used to connect power wiring 13c and 13d that transfer electric power from a battery. When the safety plug 15 is not disconnected, a signal wiring 39a and a signal wiring 39b are connected. When the safety plug 15 is disconnected, the signal wiring 39a and the signal wiring 39b are blocked. When the safety plug 15 is not disconnected, a rectangular wave signal (test signal) generated in a test signal generation part 31 reaches at a test signal detector 33. When the safety plug 15 is disconnected, the rectangular wave signal does not reach at the test signal detector. A connection member disconnection determination part 35 determines whether the safety plug 15 is disconnected or not based on a signal detected by the test signal detector 33. <P>COPYRIGHT: (C)2012,JPO&INPIT |
