Abstract

Rectifier module, including a frame forming a housing wall and having an open top and bottom, a ceramic plate cemented to the frame forming a housing bottom and having a side facing the interior of the housing and a side facing away from the interior of the housing, metallizations disposed on the side of the ceramic plate facing the interior of the housing forming conductor strips for soldering on semiconductor components, internal connecting straps, external connecting elements in the form of flat plugs having a broadened base part being soldered to one of the metallizations, an actual plug connector part being freely accessible from the top of the housing and an extension curve being disposed between the base part and the actual plug connector, the extension curve having a cross-sectional area being smaller than the cross-sectional area of the base and actual plug connector parts, a sealing compound filling substantially half of the housing, and a copper foil being disposed on the side of the ceramic plate facing away from the interior of the housing and having a thickness being substantially the same as the thickness of the metallizations.
