Abstract

The heat sink clamps 10 enable a heat sink 11 to be mounted on a printed circuit board 12 in an easy and economical manner and are particularly useful in connection with automated manufacturing systems which automatically insert components onto printed circuit boards. Fig. 1 shows the pertinent items in a disassembled manner, and Fig. 2 shows the same items after assembly. As best seen in Fig. 1, the upper extremity 13 of each clamp 10 is provided with a reverse bend so that it will bite into the corresponding heat sink fin to prevent longitudinal movement of the heat sink 11. A tab 14 is provided at the lower end of each clamp 10 for insertion into a corresponding slot 15 in the printed circuit board 12.

Heat Sink Clamp

The heat sink clamps 10 enable a heat sink 11 to be mounted on a printed circuit board 12 in an easy and economical manner and are particularly useful in connection with automated manufacturing systems which automatically insert components onto printed circuit boards. Fig. 1 shows the pertinent items in a disassembled manner, and Fig. 2 shows the same items after assembly. As best seen in Fig. 1, the upper extremity 13 of each clamp 10 is provided with a reverse bend so that it will bite into the corresponding heat sink fin to prevent longitudinal movement of the heat sink 11. A tab 14 is provided at the lower end of each clamp 10 for insertion into a corresponding slot 15 in the printed circuit board 12. These tabs 14 extend below the lower surface of the printed circuit board 12 and are twisted through an angle of approximately 45OE to lock the clamp to the board. This twisting can be done by hand with a pair of pliers or by an automatic mechanism in an automated manufacturing system.
