Rectifier module
DCFirst Claim
1. Rectifier module, comprising a frame forming a housing wall and having an open top and bottom and a depression formed in the bottom thereof, a ceramic plate, adhesive cementing said ceramic plate to said frame in said depression forming a housing bottom and having a side facing the interior of said housing and a side facing away from the interior of said housing, said frame including means for preventing said adhesive from escaping from said depression, said preventing means being a groove formed in said frame within said depression for receiving said adhesive, metallizations disposed on said side of said ceramic plate facing the interior of said housing forming conductor strips for soldering on semiconductor components, internal connecting straps connected to said frame, external connecting elements in the form of flat plugs having a broadened base part being soldered to one of said metallizations, an actual plug connector part being freely accessible from the top of said housing and an extension curve being disposed between said base part and said external plug connector, said extension curve having a cross-sectional area being smaller than the cross-sectional area of said base and actual plug connector parts, a sealing compound filling substantially half of said housing, and a thick copper foil being directly bonded to said side of said ceramic plate facing away from the interior of said housing and having a thickness being substantially the same as the thickness of said metallizations for preventing thermal tensions on the ceramic plate.
