Abstract
The invention presents a power electronic arrangement comprising a power electronic switching device, a printed circuit board for carrying control signals for driving the power electronic switching device, a housing which covers the printed circuit board, a communication device which is arranged on the printed circuit board and is accessible through a recess in the housing, and comprising a sealing device, wherein the sealing device has a sealing section which rests in a sealing manner on a first sealing face of the communication device, and wherein the sealing device has a first and second sealing lip which are each arranged circumferentially around and at a distance from the communication device, wherein the two sealing lips are connected to one another by a web and both rest on a second sealing face of the printed circuit board, and wherein the housing has a wall-like pressure device which presses on the web and in this way the first sealing lip bears against that side of the pressure device which faces the communication device, and the second sealing lip bears against that side of the pressure device which is averted from the communication device.
