A terminal crimping apparatus comprises a pressure receiving part (A1, A2) provided at a tip thereof with a pressure receiving surface (R3) for receiving a crimped terminal (1) having a barrel (11,12) whose tips are chamfered at outer peripheral sides thereof, and a caulking part (C1, C2) having a caulking surface (E) adapted to receive the tip of the pressure receiving part (A1, A2), for caulking the barrel (11,12) of the crimped terminal (1) between the caulking surface (E) and the pressure receiving surface (R3) of the pressure receiving part (A1, A2) such that one tip (11a, 12a) of the barrel overlaps the other (11b, 12b). In one aspect of the invention, the caulking part (C1, C2) has two rounding surfaces (R1, R2) smoothly integrating with each other so as to form a step portion (D) having one end located at the deepest point (P) formed at a middle portion of the caulking surface. The step portion (D) has a difference (H) in level at least equal to the thickness of the tips (t) of the barrel. According to another aspect of the invention, the deepest point (Q) of the pressure receiving part (A1, A2) and the deepest point of the caulking part (C1, C2) are located along a virtual line (L3) parallel with a symmetrical line (L2) of the barrel. <IMAGE> |
