Improved flat clip for ease of installation

Disclosed is a design for a feature of a flat metal clip used to retain heat sinks to PCBs. Benefits include improved ease of heat sink installation, reduced board damage, and improved tool longevity.

The disclosed design relocates the two holes to the top of the, top of the clip, to allow an installation tool clear and easy engagement with the clip without interference with other board components.

Conventionally, the installation tool engages the flat clip through holes on each side of the clip. This configuration requires the installation tool to be wider than the clip is long and causes excessive tool wear because of the engagement orientation. Further, it requires a larger clearance for the nearby devices on the PCB.

The disclosed design is a feature of the flat clip that requires a smaller installation tool of known design (like snap ring pliers), enables the closer packing of devices around the heat sink, and yet accomplishes ease of installation. Further, the disclosed design, by allowing the tool through the top of the clip and "inside" the clip legs, allows the installation tool to press out on the clip legs allowing the clip to drop into the board holes.
