Power transistor assembly for refrigerator - has printed circuit board with cut=out section pushed by screw onto power component such as transistor

摘要

The assembly includes a printed circuit board (3) which has a cut-out section which allows the section to move with respect to the printed circuit board plane. A screw (4) in the cut-out section allows movement adjustment. The screw also connects to the refrigerator outer section (2). The power transistor (1) is mechanically connected to the moving section, and electrically connected to the printed circuit. Its lower face lies on the refrigerator outer section which is made of a good conductor such as aluminium. Tightening the screw ensures good contact of the power transistor on the refrigerator ensuring good heat dissipation. ADVANTAGE - Reduces cost by eliminating need for extra sections mounted with clips.
