<P>PROBLEM TO BE SOLVED: To provide a technique which can form a crimping fixation state with electrical performance secured while suppressing the occurrence of cracks and breaks in a terminal fitting having a cylindrical terminal crimping part. <P>SOLUTION: A crimping die 3 comprises a first die 4 which restrains an electric wire crimping part 22 by a concave surface 40 with a shape corresponding to the electric wire crimping part 22, and a second die 5 which has a salient surface 50 paired with the concave surface 40. Here, a width d401 of a concavity 41 in the concave surface 40 and a width d501 of a salient 51 in the salient surface 50 are the same as the outer diameter d201 of the electric wire crimping part 22. The electric wire crimping part 22 is pressure-molded by the concave surface 40 of the first die 4 and the salient surface 50 of the second die 5 so that the electric wire crimping part 22 and an electric wire 11 inserted inside the cylinder are crimped and fixed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
