Terminal crimping apparatus

摘要

The terminal crimping apparatus includes a pressure receiving part provided with a pressure receiving surface for receiving a terminal having a barrel of which tips are chamfered at outer peripheral sides thereof, and caulking part having a caulking surface adapted to receive the pressure receiving part, for caulking the barrel of the terminal between the caulking surface and the pressure receiving surface of the pressure receiving part such that one of tips of the barrel overlaps the other. The caulking part has two rounding surfaces and a step portion therebetween having one end located at the deepest point formed at a middle portion of the caulking surface. The step portion has a difference in level at least equal to the thickness of the tips of the barrel. The deepest point of the pressure receiving surface and the deepest point of the caulking surface are located on a virtual line parallel with a symmetrical line of the barrel.
