CRIMPING DIE AND METHOD FOR MANUFACTURING TERMINAL-FITTED WIRE

摘要

A crimping die includes a first die for constraining the wire crimping portion by a concave die surface shaped in conformity with the wire crimping portion, and a second die including a convex die surface paired with the concave die surface. A width of a recess on the concave die surface and that of a projection on the convex die surface are equal to an outer diameter of the wire crimping portion. The wire crimping portion is pressed by the concave die surface of the first die and the convex die surface of the second die, whereby the wire crimping portion and the wire inserted into the cylindrical interior of the wire crimping portion are crimped and fixed.

1. A terminal-fitted wire manufacturing method for manufacturing a terminal-fitted wire by crimping and fixing a terminal fitting including a cylindrical wire crimping portion and a wire, comprising:
inserting the wire into the cylindrical interior of the wire crimping portion; arranging the wire crimping portion between a concave die surface formed on a first die and a convex die surface formed on a second die; and compressing and deforming the wire crimping portion and crimping and fixing the wire crimping portion and the wire inserted in the cylindrical interior of the wire crimping portion by sandwiching the wire crimping portion between the concave die surface and the convex die surface, wherein a width of a recess on the concave die surface and that of a projection on the convex die surface are equal to an outer diameter of the wire crimping portion.
