Abstract

A submodule and an assembly include a switching device having a substrate, and printed conductors arranged thereupon. The submodule incorporates a first and a second DC voltage printed conductor, to which a first and a second DC voltage terminal element are connected in an electrically conductive manner, and an AC voltage printed conductor, to which an AC voltage terminal element is connected in an electrically conductive manner. The submodule further comprises an insulating moulding, which encloses the switching device in a frame-type arrangement. The first DC voltage terminal element, by means of a first contact section, engages with a first supporting body of the insulating moulding, and the AC voltage terminal element, by means of a second contact section, engages with a second supporting body of the insulating moulding. To this end, a first clamping device is configured to project through a first recess in the first supporting body, in an electrically insulating manner, and to form an electrically-conductive clamping connection between the first DC voltage terminal element and an associated first DC voltage connecting element, and a second clamping device is configured to proj…
