<P>PROBLEM TO BE SOLVED: To provide a connection confirmation device of a wire harness capable of easily determining a connection state by detecting click sound generated in connecting the wire harness even if there is working noise or environmental noise. <P>SOLUTION: This device is used for confirming the connection state of a wire harness, and characterized by comprising: a microphone 1 for detecting sound generated in connecting the wire harness; an amplifier 2 for amplifying the sound detected by the microphone 1 to a predetermined level; a narrow-bandwidth band-pass filter 3 for passing a particular frequency component, within a signal outputted by the amplifier 2, included in the sound generated in connecting the wire harness; a level comparator 4 for comparing the output level of the band-pass filter 3 with a level reference value to output a signal by determining connection sound when the output level of the band-pass filter 3 exceeds the level reference value; and an indicator 5 for indicating connection confirmation based on the signal outputted by the level comparator 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
