Crimping device for crimping crimp pieces of a metal terminal

A crimping device, comprising:

• a crimp indenter;
• a crimp anvil,
• wherein crimp pieces of a metal terminal and a conductor wire placed on an inner side of the crimp pieces are positioned between the crimp indenter and the crimp anvil, and
• wherein at least one of the crimp indenter and the crimp anvil is movable toward another one thereof along a direction of a longitudinal center axis of the crimp indenter and the crimp anvil to crimp the crimp pieces of the metal terminal;
• at least two arch-shaped portions disposed on an inner surface of the crimp indenter, the at least two arch-shaped portions being adjacent to each other and symmetric with respect to a plane including the longitudinal center axis;
• and
• a sharply pointed portion defined by curves of the at least two arch-shaped portions intersecting on the longitudinal center axis,
• wherein curvature of each of the curves is set to be greater toward the sharply pointed portion.
