Power semiconductor module arrangement and method for assembling the same

A method for assembling a power semiconductor module arrangement, the method comprising:

• connecting a plurality of terminal elements to a substrate;
• and
• arranging a housing comprising a plurality of through holes on the substrate,
• wherein each of the plurality of terminal elements extends from the substrate in a vertical direction perpendicular to a top surface of the substrate,
• wherein arranging the housing on the substrate comprises inserting each of the plurality of terminal elements into a different one of the plurality of through holes, such that a first end of each of the plurality of terminal elements is arranged inside the housing and connected to the substrate and a second end of each of the plurality of terminal elements is arranged outside of the housing,
• wherein each of the plurality of terminal elements comprises a holding element arranged between the first end and the second end,
• wherein after arranging the housing on the substrate, each of the plurality of holding elements exerts a force on the housing, thereby holding the housing in a desired position with regard to the substrate,
• wherein at least one of the plurality of holding elements comprises a spring element,
• wherein after the arranging, the spring element is arranged outside of the housing adjacent to one of the through holes in an uncompressed state in which a width or diameter of the spring element is larger than a diameter of the through hole adjacent the spring element, thereby preventing the terminal element from moving vertically through the through hole and holding the housing in the desired position.

A power semiconductor module arrangement, comprising:

• a housing comprising a plurality of through holes;
• a substrate forming a ground surface of the housing;
• and
• a plurality of terminal elements mechanically and electrically connected to the substrate,
• wherein a first end of each of the plurality of terminal elements is arranged inside the housing and connected to the substrate,
• wherein each of the plurality of terminal elements extends from the substrate in a vertical direction perpendicular to a top surface of the substrate through one of the plurality of through holes to the outside of the housing, such that a second end of each of the plurality of terminal elements is arranged outside of the housing,
• wherein each of the plurality of terminal elements comprises a holding element arranged between the first end and the second end,
• wherein each of the plurality of holding elements exerts a force on the housing, thereby holding the housing in a desired position with regard to the substrate,
• wherein at least one of the plurality of holding elements has a conical form,
• wherein a width or diameter of the at least one holding element having the conical form decreases from a side of the at least one holding element facing the first end of the terminal element towards an opposite side of the at least one holding element facing the second end of the terminal element,
• wherein a smallest width or diameter of the at least one holding element having the conical form is smaller than a diameter of the through hole,
• wherein a largest width or diameter of the at least one holding element having the conical form equals or is larger than a diameter of the through hole,
• wherein the at least one holding element is arranged inside the through hole,
• wherein the largest width or diameter of the at least one holding element having the conical form is larger than a width or diameter of the terminal element, such that the at least one holding element having the conical form forms a collar which acts as a barbed hook, thereby preventing the terminal element from moving vertically through the through hole and holding the housing in the desired position.
