The plug connector has at least one pair of cooperating contact combs (1), with the individual contact prongs (2) of each contact comb bent into an S shape. The bridge sections (3) of both contact combs are pressed together, with a current conductor or a current rail pressed between their cooperating contact prongs. A pair of cooperating contact combs may be used for each of the external electrodes of a power semiconductor module with a number of power semiconductor chips.
