TERMINAL CRIMPING METHOD, TERMINAL CRIMPING STRUCTURE, TERMINAL CRIMPING DEVICE, AND ELECTRIC CONNECTOR

摘要

A terminal crimping method and a terminal crimping device are provided, thereby suppressing the generation of friction at an anvil and a crimper and also suppressing the generation of an upthrust portion at the upper part of a wire barrel to which a core wire of an electrical wire is crimped. A terminal crimping device (40) comprises an anvil (41) having a mounting groove (43) on which a terminal (10) is mounted, and a crimper (42) that crimps a wire barrel (31) of the terminal (10) mounted on the anvil (41). The mounting groove (43) includes a first pressing portion (43a) that presses the effective crimping portion (31a) and a second pressing portion (43b) that presses the extending portion (31b), and the bottom surface of the second pressing portion (43b) is formed to be an inclined surface expanding and opening toward a receptacle portion (20) side.
