WIPO Patent Application WO/2013/068391

A3

The invention relates to a frequency converter (10a, 10b, 10c), comprising a housing (30), a circuit board (12b) arranged in the housing, and a coupling device (20) arranged on the outside of the housing (30) for galvanically coupling the circuit board (12a) to an adjacently arranged second frequency converter (10b, 10c), wherein the coupling device (20) either has a base section (22) and a coupling element (26) that can be moved relative to the base section (22) along a defined motion path or is designed as a rigid bus bar, which is designed to be simultaneously attached to the frequency converter and to the second frequency converter, and the coupling device (22) is galvanically coupled to the circuit board (12a). According to the invention, the coupling device (22) is connected to the circuit board (12a) by means of a spring element (40), wherein said spring element (40) has a fastening section (44) on the circuit board side and a fastening section (42) on the coupling device side, which are connected to each other by an elastic spring section (46).
