- Connecting pin has a third on the side facing the connecting pin to side facing recess.
- the connecting rails are preferably designed to be planar, so that the first, second and third contact surfaces lie in a common contact plane.
- the current-carrying connection enclosing wall elements are provided in a further embodiment, which are connectable to form a busbar line with the busbars enclosing busbar boxes.
- the busbars can preferably be connected by means of the connecting rails to form an L- or T-shaped busbar section and the busbar boxes by means of the wall elements to an L- or T-shaped busbar section.
- the new device is preferably provided in an arrangement of at least a first and a second segment, in particular a first and a second power module segment of a wind turbine, and connects in the first segment preassembled first busbars with pre-assembled in the second segment second busbars, wherein the preassembled busbars are not on the outer dimensions of the segments over and their Kotaktieri parallel to each other and wherein the first and second busbars by means of two connecting means, each having a transversely extending to the contact sides connecting pin, are held together with the connecting rails under pressure.
- the device according to the invention has two connection points, wherein a first of the connection points (connecting pins) within the first segment and the second and possibly a further third is within the second segment.
