Retention module for securing heat sink

摘要

A retention module for securing a heat sink (4) to a board-mounted socket connector (2) comprises a pair of metal frames (5) and four screws (54) for securing the frames to the PCB. Each frame includes a bottom wall (50), a pair of first side walls (51) and a second side wall (52) together defining a receiving space (53) for receiving a side portion of the heat sink. The bottom wall includes an integrally formed grounding plate (50c) to contact the heat sink. The retention module further comprises a pair of clips (6) assembled to the frames thereby increasing the securing relationship between the heat sink and the frames.
