  • Patent number: 5909358
    Abstract: The present invention involves a heat sink clip which engages a slot of a heat sink to press a power component into a heat sink of an electronic module, such as a power converter circuit for a vehicle. A power converter module for a vehicle comprises a casing having at least one heat sink with a plurality of fins, power converter circuitry disposed within the casing and including at least one power component; and a clip for pressing the power component into the heat sink. The clip has a first end engaging a slot of the casing and a second end extending from the first end with a resilient biasing that presses the power component into thermal contact with the heat sink. The casing slot includes a lip which retains the clip within the slot, and a sloped surface which facilitates entry of the clip. The clip has a generally L-shaped configuration for engaging the slot, with a corner that abuts a lip of the casing slot to retain the corner within the slot.
