ABSTRACT:
A retainer (10) mechanically and thermally couples an electronic cardboard (12) to a heatsink (14) between first and second continuous surfaces (30, 38) of walls (26, 28) on a base (22). Clamping is effected by moving a pair of wedges (54) and (56) and their slanted surfaces (58, 60) against corresponding slated surfaces (42, 44) of a clamping block (36). The clamping block has an oblique surface (40) which cooperates with a surface (32) on wall (28) to move the block and its surface (38) toward surface (30), thus clamping the card at both surfaces in tight mechanical and thermal contact.
