ABSTRACT:
Apparatus and method for crimping electrical terminals in strip form wherein a head operates in a down stroke to move a crimping die toward an anvil to crimp a terminal to a conductor, to shear off the terminal and to move a cam against a cam roller on a carriage block to move the carriage block away from the crimping die and anvil, against the force of a compression spring, a feed blade pivotally supported on the block being then moved rearwardly along a terminal strip carrier portion. In the upstroke of the head, the carriage block moves into engagement with a stop screw, the feed blade being engaged in an aperture in the terminal strip carrier portion to move a terminal to a crimping position. Drag means are provided to prevent reverse movement of the terminal strip and guide means are provided including an elongated element engageable with terminal projections. The stop screw and guide element are readily adjustable to obtain accurate positioning of a terminal in the crimping means and accurate feed of the terminal strip. In the preferred embodiment, a number of different terminal strips with different spacing (within a 2:1 ratio) between the terminals, but having a standardized distance from an aperture to a terminal can be processed without major adjustment in the apparatus. This is accomplished by initially setting the stop which determines the position of the feed blade at the extreme of its forward movement toward the crimping means, so that the blade is then at the standardized distance from the anvil of the crimping means, and providing rearward travel of the feed blade to a distance greater than the spacing between terminals of any strip to be used, and less than twice the spacing between terminals of the strip with the smallest spacing between terminals to be used.
