ABSTRACT:
An automatic crimping tool having a crimping mechanism and a carrier strip feed mechanism where the crimping mechanism includes a vertically slidable ram with crimping dies and a spring loaded terminal clamping bar mechanism that has a slidable spring loaded clamping bar that presses a terminal against an anvil during the downward stroke of the ram by way of a pivotable hook mechanism attached to the clamping mechanism that engages with a pin of the bar to lift the bar off the terminal during the upward ram stroke after crimping, thereby considerably increasing the crimping cycle speed, the crimping mechanism further includes a depressor attached to the ram that depresses the carrier strip feeding mechanism in sync with the movement thereof, such that the carrier strip is pushed below the height of the anvil just prior to crimping so that bending of the carrier strip and tilting of the terminal is avoided, ensuring a high crimp quality, the feeder mechanism having a double acting motor that effectuates advance and retreat of the feeder arm that is positioned below the carrier strip guide surface such that a wire for crimping can be translated over the carrier strip directly above the terminal.
