ABSTRACT:
A terminal crimping method utilizing an anvil (5) which has a receiving surface (20) to receive an electrical terminal (4) and a punching hole (6) penetrating through the anvil (5) with an opening in the receiving surface (20). A crimper (2) has a curved surface to crimp the terminal (4). An auxiliary punch (8) has a protrusion (7) that can pass through the punching hole (6) to extend from the opening in the receiving surface (20). A wire core portion (25) is crimped to the electrical terminal (4) between the crimper (2) and the anvil (5). Then, the auxiliary punch (8) strikes out a crimped portion (21) to form a concave portion (27) in the state that the crimped portion (21) is compressed by the crimper (2) and the anvil (5).
