1. A power electronic arrangement, comprising:
a power converter module, further comprising:
a switching device with a substrate with a first and a second DC voltage conductor track and a first and a second DC voltage terminal element connected thereto in an electrically conducting manner with a respective correct polarity;
a first and a second DC voltage connection element, wherein the first DC voltage terminal element is connected to the first DC voltage connection element in an electrically conducting manner with said respective correct polarity by means of a respective first materially-bonded connection;
wherein the second DC voltage terminal element is connected to the second DC voltage connection element in an electrically conducting manner with said respective correct polarity by means of a respective second materially-bonded connection, and
wherein proximate each of the respective first and the second materially-bonded connections and between the DC voltage terminal element and the associated DC voltage connection element, the first and second DC voltage terminal element, as well as the first and second DC voltage connection element, is formed respective stacks with a respective first and a second insulation device arranged in between them viewed in the normal direction (N);
the first connection is spaced apart from the second connection perpendicular to the normal direction (N);
the first connection and the second connection do not have an overlap region;
either the first DC voltage terminal element or the first DC voltage connection element rests on a supporting device proximate one of the first connection and the second connection; and
said supporting device is one of a part of a housing of the switching device and a part of a cooling device;
the first DC voltage terminal element or the first DC voltage connection element is arranged by means of a clamping device on the support device directly adjacent to the first connection; and
wherein the clamping device is a threaded connection and with an insulating sleeve at least partially surrounding the clamping device passes in an electrically insulated manner through an opening in the first DC voltage terminal element and also passes through a second opening in the second DC voltage connection element.
