Further, the method for processing the pressure signal in the terminal crimping process comprises the following steps:
s1: constructing a waveform: constructing a time-pressure value waveform according to the pressure value detected by the pressure sensor 3, wherein the time-pressure value waveform is shown in FIG. 3;

In this embodiment, the reference waveform can be divided into three characteristic portions of an area range, a wave peak value and a core line missing, wherein the area range is as follows: according to the relation between the crimping time and the curve variation graph, the area range is a region before 90% of the peak pressure, the core wire is not pressed by the region, the pressure mainly comes from the blade curling terminal and the riveted insulating layer, and the region can be used for judging items such as poor crimping of the terminal and poor crimping of the insulating layer.
Wave peak value: the maximum point (also called bottom dead center) of the wave pressure curve is the time when the terminal is pressed most tightly (determining the terminal pressing height and the tensile force), and the pressure at this time is mainly generated when the core wire is pressed. Meanwhile, the pressure of the point can reflect the change of the terminal crimping height so as to judge the bad items generated by the change of the core wire and the crimping height.

In the present embodiment, the peak value mainly reflects the core wire variation and the crimp height variation, and when the core wire failure (usually, core wire missing) occurs, the bottom dead center pressure value varies due to the change in the core wire area. The range of tolerance can be estimated by the percentage of the total area occupied by the core wire increase and decrease. Therefore, the tolerance calculation method specifically includes: the sectional area of the acquisition terminal S1, the total sectional area of the cable conductors S2, the sectional area of the single core conductor S3, and the variation V of the lack of one core conductor are:
