ABSTRACT:
A method and apparatus is provided for cutting and crimping connecting terminals which are to be fitted in a connector housing installed in an automobile. The device includes a crimping unit and a cutting unit. The crimping unit includes a shaping die, a cover-squeezing-protrusion crimping punch, and a core-squeezing-protrusion crimping punch, and receives a plurality of connecting terminals connected through coupling protrusions to a carrier plate, to crimp the cover squeezing protrusions and the core squeezing protrusion of each connecting terminal respectively over the cover and the core of a covered conductor. The cutting unit includes a cutting die, and a cutting punch, and cuts the coupling protrusions of the connecting terminals. The working surface of the shaping die includes a cover-squeezing-protrusion supporting surface which is made up of a sunk surface which is a depth smaller than the thickness of the cover of the covered conductor, and a curved surface which is arcuately raised to support a predetermined part of the coupling protrusion of the connecting terminal, so that the predetermined part of the coupling protrusion, when cut, forms no sharp end.
