Abstract

A CPU and heat sink mounting arrangement, which includes a locating plate having downward hooks inserted through respective through holes at a CPU connector and a heat sink, and two retainer strips attached to respective transverse grooves at the heat sink and having retaining holes fastened to the downward hooks of the locating plate to secure the CPU connector and the heat sink together, wherein the retainer plates each have a finger strip for operation by hand to disengage the respective retaining holes from the downward hooks, and the locating plate has two transverse spring leaves at two opposite ends, which push the locating plate away from the CPU connector after disengagement of the retainer plates from the downward hooks of the locating plate.

Claims

1. A CPU and heat sink mounting arrangement comprising:

a heat sink having parallel fins and two transverse grooves at a top side wall thereof, and two pairs of through holes respectively disposed in said transverse grooves;

a CPU connector holding a CPU, said CPU connector having a plurality of through holes corresponding to the through holes at said heat sink;

two retainer strips respectively attached to the transverse grooves at said heat sink, said retainer strips each comprising a hooked portion curved in one direction at one end and hooked on one longitudinal side edge of said heat sink, a springy finger strip curved in the reversed direction at an opposite end, and two retaining holes spaced between said hooked portion and said finger strip corresponding to the through holes in one transverse groove at said heat sink; and

a locating plate attached to said CPU connector at one side opposite to said heat sink, said locating plate comprising two pairs of downward hooks bilaterally perpendicularly raised from two opposite ends thereof and respectively inserted through the through holes at said CPU connector and the through holes at said heat sink and hooked in the retaining holes at said retainer plates, and two spring leaves transversely disposed at the two opposite ends outside said downward hooks, said spring leaves each having a middle part connected to said locating plate, and two opposite ends sloping outwardly downwards and then respectively curved upwards.
