In parallel screw connections, which are preferably used in series terminals, the transmission of force from the connection screw to electric conductors which have different diameters is not always optimal. As a solution, the clamping element is mounted in or on the connection housing both in a movable manner as well as in a rotational manner about a rotational axis. By screwing the connection screw, the clamping element is moved in the direction of the electric conductor, mechanically contacts the electric conductor, is rotated by further screwing the connection screw about the rotational axis, and thus presses the electric conductor against the busbar with a corresponding degree of force. In this manner, an optimal pressing force is ensured independently of the respective diameter of the electric conductor.

A parallel screw connection comprising at least one connection housing, a connection screw and a clamping element, wherein the clamping element is mounted in or on the connection housing both in a displaceable manner and also in such a manner as to be able to rotate about an axis of rotation.
A method for providing an electrical contact between an electrical conductor wherein a connection screw is screwed into the connection housing in a parallel manner with respect to the current rail and the electrical conductor, and as a consequence presses a clamping element against the electrical conductor and presses this electrical conductor against the current rail, as a consequence of which the electrical conductor makes electrical contact with the current rail, wherein the clamping element is initially displaced in a direction towards the electrically conductor by virtue of screwing in the connection screw, subsequently makes mechanical contact with the electrical conductor and rotates about an axis of rotation by virtue of screwing the connection screw further in and as a consequence presses the electrical conductor against the current rail.
