ABSTRACT OF THE DISCLOSURE The present invention relates to a device for crimp- ing and shearing contacts of a contact strip. In producing contact strips, contacts punched and formed of sheet metal blanks are interconnected by a metal strip. In known appar- atuses in which strip contacts are crimped onto conductors, shearing action is accomplished by providing cooperating shearing knives or shearing blocks on a movable crimping Jaw and a fixed crimping jaw, respectively. A disadvantage of this design is that the movable crimping jaw must traverse a relatively large stroke when raising the shearing device from the stationary crimping jaw so far that the next con ductor to be crimped can be easily introduced. The present invention provides a device with an improved shearing means not subject to the above shortcomings. According to the present invention a shearing device is provided in the form of a leaf spring adapted to fit flat on the contact strip in a position flush with the point of shearing, and cooper- ating with the fixed crimping jaw to effect the shearing action. The contact resting on the stationary crimping jaw is supported by the crimping jaw, and the leaf spring pro- jects laterally beyond the crimping jaw and is adapted to be moved through a shearing stroke relative to the fixed jaw by means of a thrust member on the movable jaw.
