Abstract

The crimping apparatus crimps a conductor of a FFC (flexible flat cable) to a terminal. The crimping apparatus has a crimping portion and a pressing portion. The crimping portion has an anvil and a crimper which pinch the terminal and the conductor of FFC therebetween. The pressing portion has a pair of stopping bars. The stopping bars each are inserted into a through hole defined in the crimper. The stopping bars of the pressing portion press the conductor positioned on a bottom wall of the terminal against the bottom wall. The crimping portion crimps crimping pieces of the terminal with the stopping bars pressing the conductor against the bottom wall.

Claims

1. A crimping apparatus for positioning a conductor of a flat circuit on a bottom wall of an electrical connection portion of a terminal and for crimping the terminal by a crimping piece raised from the bottom wall to press-fit the conductor to the terminal, the crimping apparatus comprising:

pressing means for pressing the conductor positioned on the bottom wall against the bottom wall; and

crimping means for crimping the crimping piece with the conductor being pressed on the bottom wall by the pressing means,

wherein the conductor is covered with insulating material except for at least one end portion and is bent along the bottom wall at an uninsulated end portion so that the uninsulated end portion closely contacts the bottom wall when pressed by the pressing means, and

wherein the crimping means has a pair of dies coming close to and apart from each other to pinch and crimp the crimping piece, and the pressing means has a plurality of stopping bars, each bar passing through a through hole defined in one die and retractively extending toward the other die, and

the plurality of the stopping bars are disposed parallel to each other across the width of the terminal.
