Abstract:
A method for testing the crimped state of a test terminal on the basis of a waveform of characteristic values obtained in the process of crimping the test terminal on a core of an electric wire, comprising the steps of:acquiring a reference waveform from a characteristic waveform when a first terminal has been crimped normally, and dividing the reference waveform into first plural reference waveform segments, the reference waveform showing changes in load at regular time intervals when the first terminal is crimped normally, each of the first plural reference waveform segments corresponding to a segment of time elapsed when the first terminal is crimped normally; dividing the waveform obtained when the test terminal is crimped on the electric wire into second plural waveform segments corresponding to those of the reference waveform; and deciding whether or not the crimped state of the test terminal is good on the basis of the first reference waveform segments of the reference waveform and the second waveform segments of the waveform obtained when the test terminal is crimped.
