Abstract: An auxiliary connector device connects a conductor with an electrical component mounted in a terminal block upon which the connector device is mounted, including a contact arrangement extending through aligned outlet and entry openings contained in the auxiliary connector device and the terminal block, respectively, thereby to connect with the electrical component a bus bar to which the conductor is clamped. The contact arrangement includes a contact screw rotatably connected at one end with the auxiliary connector device and in electrical engagement with the bus bar, the other end of the contact screw being threadably connected with the terminal block. Upon rotation of the screw in a given direction; a contact sleeve arranged concentrically about the screw is longitudinally displaced into electrical engagement with the electrical component. The auxiliary contact device is sectional, thereby to permit use of a selected one of a plurality of contact arrangements having different lengths.
