Abstract

Pliers for dressing conductor ends have two handles (3, 11) which can move relative to one another, a plurality of dressing stations for the conductor ends, and a drive device (21) via which the dressing stations can be driven during operation of the handles (3, 11). One of the dressing stations is constructed as a crimping drum (18) which can be displaced axially and is supported such that it can rotate and be coupled to the drive device (21) in the axially displaced position over only one dressing process. In this position, the station can be locked via a flange (52) which projects radially from it. This flange (52) extends over the overall circumference of the crimping drum (18) and has at least one recess (51). A locking tab (50a), which is arranged in a fixed position on the body (2) of the pliers and is radially opposite the flange (52), engages, in the undisplaced axial position of the crimping drum (18), into the recess (51), to be precise up to a point close to the outer surface of the crimping drum (18) while, in the axially displaced and rotated position of the crimping drum (18), the locking tab (50a) comes to rest above the outer surface of the crimping drum and engage…
