Abstract

A spring clip for clamping a heat sink module which has a plurality of upwardly extending cooling elements to an electronic module. The spring clip includes a horizontal grid like foot portion which engages the upper surface of the heat sink module a vertical leg portion which extends along the side of the heat sink module and the electronic module and a bendable and resilient connecting portion which extends from the inner end of the foot portion to the upper end of the leg portion. The electronic module has a first latching element at its side surface for engaging a complementary second latching element which forms part of the vertical leg portion of the spring clip. The spring clip is rendered from a non-clamping position in which the latching element of the clip is above the latching element of the electronic module to a clamping position by bending the connecting portion downwardly from its inner end to lower the vertical leg portion so that the first and second latching elements are engaged.
