ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an equipment for securing a heat dissipator of CPU, and particularly to one which is made to have a single part, therefore same doesn't need assembly in manufacturing.
CPU would produce a large amount of heat when working, and the large amount of heat has to be dissipated, otherwise the CPU is likely to break down, or get damaged. Therefore, a heat dissipating equipment is fitted onto a CPU to dissipate the heat produced by the CPU when working.
One common CPU heat dissipating equipment has a flat base, and several lines of radiating fins sticking up from the upper side of the flat base. The heat dissipating equipment is fixedly disposed on the upper side of the CPU so that heat from the CPU can pass through the radiating fins to be dissipated by cooling air from an electric fan.
Referring to
FIG. 6
, a conventional securing equipment for a CPU heat dissipator of this kind has a middle pressing part
10
and connecting parts
101
and
102
at two ends. The equipment is made by a punching and pressing machine. The connecting parts
101
and
102
have holes
1011
and
1012
respectively. The hole
1011
of the securing equipment is connected to a fixing protrusion
201
of a socket
20
, which a CPU is connected to with the middle pressing part
10
being disposed on a central passage through radiating fins
301
of the heat dissipator
30
. Then, the connecting part
102
is pressed for the connecting hole
1021
to be connected to a fixing protrusion
202
of the socket. Thus, the securing equipment locks and the pressing part
10
thereof pressing the heat dissipator
30
to fix the same in position.
However, the securing equipment is found to have drawbacks as follows:
1. The computer user has to remove the securing equipment by means of suitable tools such as a screwdriver for permitting the heat dissipator
30
and the CPU
40
to be removed for maintance, replacement, or upgrading thereof. Consequently, the securing equipment is likely to get deformed after many times of removal for the frequent maintance, replacement and upgrading of the computer.
2. Furthermore, because the securing equipment is made of carbon steel, and needs heat treatment, there can be many deformed failure products in manufacturing and the heat treatment.
Referring to
FIG. 7
, another conventional securing equipment
50
has a middle elongated pressing part
501
, and a first and a second connecting parts
502
and
503
at two ends. The connecting parts
502
and
503
have connecting holes
5021
and
5031
respectively. The second connecting part
503
further has a positioning part
504
, to which an inverted-L shaped removing member
505
is connected. The connecting parts
502
and
503
are connected to a respective oen of the fixing protrusions
201
and
202
of a socket
20
, which a CPU
40
is fitted to, for fixing a heat dissipator
30
on the upper side of the CPU
40
in position with the elongated pressing part
501
pressing the heat dissipator
30
. To remove the securing equipment
50
, the removing member
505
is depressed, and pushed inwardly of the heat dissipator
30
for the connecting hole
5031
to separate from the fixing protrusion
202
; thus, the securing equipment
50
can be removed.
However, because the securing equipment
50
consists of two separate parts, an assembly thereof is needed in the manufacturing after the two parts are made by a punching and pressing machine, needing additional labor and increasing the cost of the securing equipment. And, because the two parts are made of carbon steel, they are likely to get deformed in the necessary heat treatment.
SUMMARY OF THE INVENTION
Therefore, it is a main object of the present invention to provide a securing equipment for a heat dissipating device of a CPU, which is made by means of punching and pressing a stainless spring steel, and which needs no assembly because the whole body is formed in the pressing and punching process.
And, it is another object of the present invention to provide the securing equipment with easiness of use.
The securing equipment of the present invention includes a middle pressing part a first and a second connecting parts and an L-shaped removing part.
The whole part of the securing element. is formed by punching and pressing a stainless spring steel. The middle pressing part is folded at an angle to have a pressing point on a lower side, and has a pair of anti-skid protrusions sticking sideways therefrom.
The first and the second connecting parts are formed at two end of the middle part, and each has a connecting hole. The L-shaped removing part sticks out from a lower-end of the second connecting part, and is pivoted upwards to abut the second connecting part in an inverted position with a third connecting hole thereof communicating with the second part communicating hole. The removing part has a pair of fixing wings bent towards the second connecting part to fix same to the second part. The removing part has a moved portion on a top at the inverted position.
To use the securing equipment, the CPU is fitted onto a socket, and the heat dissipator is disposed on the CPU. Then, the first part hole, and the second and the third connecting holes engage a respective one of two end fixing protrusions of the socket with the pressing point pressing the heat dissipator. To remove the securing equipment, the moved portion is depressed and pushed towards the middle part for the second and third holes to disengage the corresponding fixing protrusion. The anti-skid protrusions will pass through between radiating fins of the heat dissipator to prevent the equipment from moving back and forth on the heat dissipator.
