Abstract: A retaining device for attaching a heat sink (2) to a CPU (3) mounted on a circuit board (4). The retaining device includes a pair of clips (1), a backplate (6), and four pins (5). Each clip includes a central pressing portion (10), two resilient portions (12) adjacent the pressing portion, two shoulders (13) adjacent the resilient portions, and two arms (17). Each shoulder defines first and second cutouts (14a, 14b). Each pin forms a blocking head (50), and a bottom blocking stop (58). The pins are extended through the backplate, the circuit board and the heat sink. The heads are initially received through the first cutouts, and then engaged on the shoulders at the second cutouts. The heads press downwardly on the clips, and the stops press upwardly on the backplate. Thus, the clips and the backplate firmly sandwich the heat sink, the CPU and the circuit board therebetween.

Abstract: A sealing mechanism for a customer replaceable unit (CRU) within a computer system is provided. The sealing mechanism comprises a faceplate for the CRU, wherein insertion and extraction latches are recessed into a trench within that faceplate. The backside of the faceplate has a protruding rim around the perimeter. The rim engages a groove in the subsystem enclosure, which surrounds the aperture that the CRU engages. Since the faceplate incorporates a perimeter ridge and a trench structure, the interacting groove follows the contour of the trench. Thus the rim and groove both trace the faceplate trench around the faceplate. The groove in the subsystem enclosure has an entrenched section at both ends of the receptacle perimeter that accommodate sections of the faceplate rim that trace the trench in the faceplate.
