ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a clip, and particularly to a spring clip which can be easily assembled/disassembled to/from a heat sink and an associated electronic device.
Referring to
FIGS. 4 and 5
, a conventional clip
1
used for attaching a heat sink
9
to an electronic element
8
comprises a pressing body
2
for engaging in a positioning groove
90
defined in the heat sink
9
, and a pair of latching arms
4
substantially perpendicularly extending from opposite ends of the pressing body
2
. A sloped portion
3
connects the pressing body
2
with the latching arm
4
. A latching opening
5
is defined in each latching arm
4
for engaging with a corresponding latching projection (not shown) formed on the electronic element. A manipulating tab
7
integrally extends outward from a slot
6
defined in each latching arm
4
for a tooling (not shown) to disassemble the clip
1
from the heat sink and the electronic element.
However, disengagement slippage between the tooling and the handling tabs
7
of the clip
1
is frequently experienced during actual operations since the handling tabs
7
are usually too small to be held firmly. Moreover, if large snapping force is exerted on the handling tabs
7
of the clip
1
by the tooling, the handling tabs
7
are easy to be broken off from the clip
1
, thus, it is even more difficult to disengage the clip
1
from the electronic element
8
. Moreover, the manipulating tabs
7
can be easily broken off from the clip
1
if it is overloaded.
Therefore, an improved clip is desired.
BRIEF SUMMARY OF THE INVENTION
A main object of the present invention is to provide a clip for attaching a heat sink to an electronic element and which can be readily disassembled from the heat sink and the electronic element.
Another object of the present invention is to provide a clip for attaching a heat sink to an electronic element which fulfills the miniature requirements.
A clip for mounting a heat sink to an electronic element in accordance with the present invention comprises a pressing body and a pair of latching arms extending from opposite ends of the pressing body. A sloped portion connects the pressing body with each latching arm. Each latching arm defines a latching opening for engaging with a corresponding latching projection of the electronic element. A handling tab is integrally extends outward from one of the latching arms in which a slot is defined. Thus, when disassembling the clip from the electronic element is needed, a tooling, such as a screwdriver, may be partially inserted into the slot of the clip and pivoted such that the latching opening of the clip is easily disengaged from the latching projection of the electronic element.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
