ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a clip, and particularly to a clip for a heat sink which readily attaches the heat sink to an electronic device.
2. The Related Art
During operation of an electronic device in a computer system, a large amount of heat may be produced. Such heat must be quickly removed from the electronic device to prevent the computer system from becoming unstable or being damaged. Consequently, a heat sink is frequently attached to the electronic device to remove heat therefrom, and a clip is used to secure the heat sink to the electronic device.
Referring to
FIG. 3
, a conventional clip
1
comprises a pressing body
2
and two arms
3
extending downwardly from opposite ends of the pressing body
2
. Each arm defines two apertures
4
,
5
arranged one above the other. The lower apertures receive corresponding tabs (not shown) formed on a socket (not shown) on which a CPU (not shown) is mounted, for attaching a heat sink to the CPU. The upper apertures
5
are designed to engage with a tool such as a screwdriver. The tool is used for engaging the lower apertures
4
with the tabs, and for disengaging the lower apertures
4
. However, it is inconvenient to have to use a tool, especially within the limited confines of a computer case.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a clip for readily assembling a heat sink to an electronic device, and for readily disassembling the heat sink therefrom.
To achieve the above-mentioned objects, a heat sink clip comprises a body and an R-shaped handle. The body comprises a pressing portion, and first and second spring portions extending from opposite ends of the pressing portion. First and second legs respectively depend from free ends of the first and second spring portions. A catch is stamped upwardly from the second spring portion and then bent toward the pressing portion. A bent tab is stamped outwardly from the second leg and then bent downwardly. The handle comprises first and second connecting portions, and an actuating portion between the first and second portions. First and second fixing holes are respectively defined near the free ends of the first and second portions, and respectively engage with the catch and bent tab of the body.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed embodiment of the present invention with attached drawings, in which:
