Abstract

In a terminal crimped state testing method, in step S1, a reference waveform is created on the basis of a load when a terminal in a good crimped state is obtained, and the reference waveform is divided into plural reference waveform segments to set singular points. In step S2, the reference waveform segments containing singular points of the segments are integrated. In step S3, a characteristic waveform is created on the basis of the load when a crimping terminal to be tested is obtained. The characteristic waveform thus created is divided into plural sample waveform segments and the waveform segments corresponding to the reference waveform segments are integrated. In step S4, the integrated values of the reference waveform segments are compared with those of the sample waveform segments, thereby deciding whether the crimped state of the crimping terminal is good or not. In this configuration, the terminal crimped state can be stably tested, the defectiveness is precisely detected, and the time taken for testing can be shortened.
