ABSTRACT:
Heat-generating power transistors (3) hanging from a circuit board (2) are mounted pressed flush against the inside surface of a heat dissipating thin sheet metal box (1), by using spring metal band clips (4) completely mountable from outside the metal box (1), by insertion of a foot end (4b) of each clip into a first slot (6) in the box and snapping an opposite end (4a), bent to form a spring fluke, into a second parallel slot (5). Slots (6,5) and a clip recessing trough (7) between them can be stamped in the thin sheet metal box bottom (1b).
