US 11,109,477 B2 · Heat sink fastening mechanism for use with electrical connector

Abstract

A fastening mechanism for retaining a heat sink upon the CPU includes a fastening seat surrounding the connector, and a pair of fastening clips. The fastening seat includes four alignment posts at four corners, and the pair of fastening clips are attached at two corresponding diagonal corners. Each fastening clip includes a mounting section secured to the corresponding post, a latching section for temporarily holding the heat sink, and a resilient arm for upwardly urging the heat sink. Each alignment post is equipped with a screw nut and a coil spring so as to reinforce the downward pressing forces against the heat sink for assuring reliable connection between the CPU and the contacts of the electrical connector for better electrical transmission and intimate contact between the CPU and the heat sink for efficient heat dissipation.
