ABSTRACT:
A tool for crimping a terminal to an end of an electrical conductor has a movable fulcrum which reduces hand force required to operate the crimping tool. The tool includes main body having a handle end and a first jaw disposed remote from the handle end. A second jaw is pivotally connected to the main body between the handle end and the first jaw. The a second jaw cooperates with the first jaw to perform the crimping as the second jaw is pivoted toward the first jaw. A movable handle is operably connected to the second jaw to pivot the second jaw toward the first jaw. A driver link has a first end pivotally connected to the main body, and a second end of the driver link has a slidable connection with the movable handle. The slidable connection includes a pivot pin which is slidable in a slot defined in the movable handle. As the movable handle is operated to pivot the second jaw toward the first jaw, the fulcrum is displaced relative to the movable handle between at least a first position and a second position, thereby modifying a distance between the fulcrum and the connection of the movable handle with the second jaw.
