Abstract
A frequency converter () includes a housing (), a circuit board () arranged in the housing, and a coupling arrangement () arranged externally on the housing () for galvanically coupling the circuit board () to an adjacently arranged second frequency converter (), wherein the coupling arrangement () either comprises a base portion () and a coupling member () movable with respect to the base portion () along a defined movement path, or is formed as a rigid busbar which is designed for simultaneous attachment to the frequency converter and the second frequency converter, and the coupling arrangement () is galvanically coupled to the circuit board (). The coupling arrangement () is connected to the circuit board () by a spring element (), wherein this spring element () has a fastening portion () on the circuit board side and a fastening portion () on the coupling arrangement side. The fastening portions are interconnected by a resilient spring portion ().
