ABSTRACT:
A wire-crimping device detects if an electrical terminal is stuck to a crimper after crimping, thereby effectively eliminating deformed terminals. Electrical wire-crimping device (1) has a ram (42) slidably mounted to a housing (4). A reflection light sensor (60) is mounted to the housing (4), and a pathway (80) that communicates with a wire-crimping member (40) is located in the ram (42). If an electrical terminal (30) should stick to crimpers (50, 52) after crimping, and if the wire-crimping member (40) mounted to the ram (42) rises, a wire depressor (54) will also rise, and an upper end of the wire depressor (54) will block the pathway (80). As a result, the light emitted from the reflection light sensor (60) will be reflected and detected by a light sensor, and it will be electrically detected that a defective part has been produced.
