Abstract:

A machine (10) for receiving and operating a terminal applicator (12) in the attaching of an electrical terminal (14) to a conductor includes a magnetic power unit (28) having a fixed electromagnet (30) attached to the frame (20) and a movable electromagnet (32) coupled to the terminal applicator (12). The machine includes a cycling mechanism (86) for manually moving the movable electromagnet (32) through the power and return strokes of the terminal applicator (12). The cycling mechanism (86) includes a lead screw (88) having a nut (102) in threaded engagement therewith that moves vertically when the lead screw is rotated. A latch (110) attached to the nut (102) pivots into an opening (112) in the periphery (114) of the movable electromagnet (32) when the lead screw is rotated in one direction (130). As the lead screw (88) is rotated further the latch (110) carries the movable electromagnet (32) downwardly through its power stroke. When the lead screw (88) is rotated in the opposite direction the latch (110) carries the movable electromagnet (32) upwardly through its return stroke.
