At least one (18, 19) of the dressing stations (4, 8; 18, 19) can be coupled to the drive device (10, 12, 20) with the aid of the conductor end (28) which is to be dressed. The dressing station which can be coupled to the drive device is thus driven only when this is also actually required.

Abstract: The invention relates to a method of tightly electrically connecting an electric cable (12) to an end member (10) such as an electric contact, it is proposed that the partly bared or stripped end of the cable be introduced into a stepped blind hole (26) formed in a rear connection part (10b) of the member (10). More specifically, the bared cable end is received in two cylindrical sections (26a,26b) of the hole (26), in which have been inserted beforehand a transparent sleeve (30), capping an inspection hole (32), and a metal interface ring (34). The unbared part of the cable is received in a cylindrical entrance section (26c) of the hole (26). Then, by wiredrawing, the partly truncated cone-shaped, outer surface of the part (10b) is deformed in order to give it a cylindrical shape.

Abstract: An electrical terminal applicator is provided for crimping terminals onto electrical wires. An applicator ram is movable mounted on an applicator frame and is drivable by a press ram through a working stroke towards, and a return stroke away from, a crimping anvil. A crimping die is mounted on the applicator ram for cooperation with the anvil to crimp a portion of a terminal onto a wire during each working stroke of the applicator ram. A pneumatic piston-and-cylinder device is mounted directly on the applicator frame adjacent the applicator ram and is connected to the crimping die for moving the crimping die through a first portion of movement into engagement with an uncrimped terminal to preposition the terminal for crimping thereof.
