Fastening systems for power modules

摘要

Fastening systems for power modules including molded body (2) with flat surface (2a) bearing on supporting structure, and a plurality of protruding contact pins (3). A pressing element (5) presses a power module (1) on a side opposite the supporting structure. A connecting element (11) fastens the pressing element (5) on the supporting structure and imparts a force pressing towards the supporting structure. Sections (9, 10) formed on the pressing element (5) have outer edge regions (10) acting elastically on edge regions of the power module (1) in the fastened position. These edge regions are loaded with a pressing force towards the supporting structure. Such power modules (1) are useable with such fastening systems, as are the pressing elements (5).

主权项

1. A power module fastening system comprising:
a power module moulded body, said moulded body having a bearing surface configured to bear on a support, said moulded body having a second surface opposite said bearing surface, said second surface having a plurality of receptacles, said receptacles being situated at edge regions of said second surface; a press plate configured to contact said second surface, said press plate including a plurality of extending sections, each of said extending sections having at least one respective outer edge portion, each of said respective outer edge portions of said extending sections being received in at least one respective receptacle of said second surface; and, a connector configured to mount said press plate in contact with said second surface to push said bearing surface onto the support in a fastened position.
