ABSTRACT:
A powered hand tool (10) is disclosed for crimping terminals (30) onto a conductor. The tool includes a linear actuator (18) for driving a cam (64) along a linear path (272). The cam (64) has camming surfaces (90, 92) that interact with a pair of followers (192, 194) to first cause the crimping mechanism (16) to crimp the terminal and then, early in the return stroke, to open the crimping mechanism (16) so that the crimped terminal (30) can be removed and the next terminal fed into position during the remainder of the return stroke. The cam (64) includes two part camming surfaces (94, 96 and 98, 100), both parts of which are tracked by the followers (192, 194) while performing the crimping operation. Once the followers reach a certain point along the camming surfaces (90, 92) a gate member (68) moves one of the parts (96, 100) out of alignment so that upon the return stroke the followers (192, 194) return by a different path, thereby opening the crimping mechanism early in the return stroke.
