Patent ID: 7036226

Claim:
A crimp state estimation apparatus for estimating a crimp state of a crimp contact terminal when the crimp contact terminal comprising a bottom wall for positioning a core wire of an electric wire and a pair of crimp pieces upright from opposite margins of the bottom wall and the core wire are held between an anvil and a crimper and are crimped, the crimp state estimation apparatus comprising: an information input section for inputting information on the crimp contact terminal, the electric wire, the anvil, and the crimper and an input compression ratio of the core wire; and an estimation unit for calculating a total length of the bottom wall and the pair of crimp pieces after crimp in a cross section orthogonal to the core wire based on the information and the input compression ratio and estimating a cross-sectional shape of the bottom wall and the pair of crimp pieces after crimp based on the total length.
