ABSTRACT:
A method of press-molding defectiveness detection adapted for the detection of the press-bonding defectiveness of a terminal which is attached to the end of a covered wire so that a wire barrel and an insulation barrel of the terminal are press-bonded to a conductor portion at the end of the covered wire and a covered portion of the wire, respectively, by press-molding. A profile of a press-bonding load acting on the terminal during terminal press-bonding operation is detected, and the press-bonding defectiveness of the terminal is determined by comparing the detected press-bonding load profile with a reference press-bonding load profile. The press-bonding defectiveness of the terminal may be determined, as required, by comparing the integral value of the press-bonding load, calculated on the basis of the detected press-bonding load profile, with a predetermined reference value. Alternatively, the defectiveness may be determined by comparing a press-bonding load value at at least one point of time and the maximum press-bonding load value with predetermined reference values individually corresponding thereto. Preferably, the press-bonding defectiveness of the terminal is determined by separately detecting profiles of press-bonding loads acting on the wire barrel and the insulation barrel, and comparing these profiles with reference press-bonding load profiles individually corresponding thereto.
