ABSTRACT:
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to an improved structure of a CPU securing seat, and in particular, to a CPU securing seat facilitating assemble/dissemble of CPU without deforming the insertion legs of the CPU.
b) Description of the Prior Art
As shown in
FIG. 1
, a conventional CPU securing seat comprises a seat body
2
, a covering body
3
, and a pulling rod
4
, wherein the seat body
2
is provided with a plurality of holes
20
corresponding to the position of the insertion legs
10
of the CPU
1
. At the left side bottom corner, a sloping face
200
is provided so as to form a tapered passage
201
. Within the hole
20
, a sloping disc
21
is provided and the bottom section of the sloping disc
21
is extended to form a securing leg
210
for mounting and welding onto a mother board
11
. On the top side of the seat body
2
, an elongated recess
22
extended to the two lateral sides of the seat body
2
is provided for the mounting of the pulling rod
4
. The center of the recess
22
has a larger cavity
23
and the bottom section of the two sides of the seat body
2
is provided with a sliding slot
24
. At one side of the sliding slot
24
, a plurality of notches
25
are provided.
The covering body
3
is mounted onto the top of the seat body
2
and the corresponding positions of the holes
20
are provided with a plurality of circular holes
30
for the insertion of the insertion legs
10
of CPU
1
. The front side of the bottom section of the covering body
3
is provided with an engaging block
31
, and a lateral disc
32
is extended downwardly from the two sides of the covering block
3
for mounting the covering body
3
at the two sides of the seat body
2
. The inner side of the lateral disc
32
is provided with a plurality of protruded blocks
33
for sliding into the sliding slot
24
via the notch
25
of the seat body
2
so that it can move within the sliding slot
24
.
The pulling rod
4
is an L-shaped rod body and one side of the rod body is mounted within the elongated recess
22
of the seat body
2
and the rod
4
is bent upward to form an urging section
40
at the corresponding position to the cavity
23
. The other side of the rod body is extended out from the seat body
2
and the front end section is bent to form a board-pulling section
41
.
Referring to
FIGS. 2 and 3
, when the pulling rod
4
is moved upward to an upright position, the urging section
40
moves the engaging block
31
of the covering body
3
forward such that the covering body
3
(at the seat body
2
) slides forward and the plurality of holes
30
are in alignment with the wider area of the holes
20
of the bottom section of the seat body
2
. Thus, the insertion legs
10
of the CPU can be inserted into the holes
30
. After that, when the pulling rod
4
is pressed, at this moment, the urging section
40
, by means of the engaging block
31
of the backward push of the covering body
3
, causes the covering block
3
to slide backward. Thus, the insertion legs
10
of the CPU
1
are driven to move toward the passage
201
, and one side of the leg
10
urges the sloping disc
21
to deform and secure to the passage
201
.
The conventional CPU securing seat has been widely used but in actual assembling or application, numerous drawbacks are found as follows:
a) Easy deformation of CPU insertion legs, or worn out of insertion legs or sloping disc. In the conventional CPU securing seat, the covering body
3
is moved so as to move the mounted CPU
1
to cause the bottom section of the insertion legs
1
to move to the passage
201
such that one side of the insertion legs
10
urges the sloping disc
21
to deform and they are clipped at the passage
20
. Thus, the insertion legs
10
of the CPU
1
will deform as a result of urging with the sloping disc
21
. If the insertion legs
10
deform, the CPU
1
cannot be used again. In addition, the mutual urging of the insertion legs
10
may cause the sloping disc
21
to wear out and will not function properly.
b) Inconvenient in operation. In the conventional CPU securing seat, the pulling rod
4
is either pulled up or pushed down so as to move the covering body
3
forward and backward. However, there are numerous electronic components welded on the mother board
11
and are located so close to each others. Using fingers to trigger the pulling rod
4
will interrupt these components, which causes inconvenience in operation. In addition, the wet fingers may contact with these components which cause short circuit.
SUMMARY OF THE INVENTION
Accordingly, it is highly desirable to alleviate the drawbacks of the conventional CPU securing seat structure by provided an improved structure of CPU securing seat.
The main object of the present invention is to provide an improved structure of a CPU securing seat comprising a seat body, a covering body and controlling device, characterized in that the seat body is provided with a plurality of triangular holes, and each of the triangular holes is provided with an inverted V-shaped clipping disc having securing legs extended from the bottom section thereof, the inverted V-shaped clipping disc is extended upward to the pore of the covering seat, and two lateral sides of the top section of the hole are extended to form a protruded rail and the covering body is provided with a plurality of triangular pores and one side of the pore is extended to form a notch, the bottom section of the pore is extended to form an engaging slot; the controlling device is mounted at the top section of the covering body to control the forward and backward movement of the seat body, thereby the controlling device is used to control the covering body to move backward so that the inverted V-shaped clipping disc is clipped by the notch to form an inverted U-shaped to clip the insertion legs of the CPU.
The above objects and other advantages of the present invention will be more apparent by describing in detail preferred embodiment thereof with reference to the drawings in which:
