Patent ID: 8134837

Claim:
A power semiconductor module system, comprising: a power semiconductor module including a bottom side with a first thermal contact surface; a heat sink including a top side with a second thermal contact surface; at least one fastener by means of which the power semiconductor module is conjoinable with the heat sink; wherein the power semiconductor module includes a number N1≧1 of first positioning elements, the heat sink a number N2≧1 of second positioning elements, each of the first positioning elements corresponding to one of the second positioning elements and forming a pair therewith; wherein the power semiconductor module and the heat sink are alignable relative to one another so that the two positioning elements of each of the pairs are interfitted when the power semiconductor module is mounted on the heat sink; and wherein the power semiconductor module system has at least one of a first configuration and a second configuration, the first configuration comprising at least one of the first positioning elements being movable relative to the first thermal contact surface and being resiliently located by means of a resilient key for forced insertion at least partly into a receiving space provided on the power semiconductor module when mounting the power semiconductor module on the heat sink; and the second configuration comprising at least one of the second positioning elements being movable relative to the second thermal contact surface and being resiliently located by means of a resilient key for forced insertion at least partly into a receiving space provided on the heat sink when mounting the power semiconductor module on the heat sink.
