ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention discloses an expanding card fixing structure, especially using a
-type or L-type batten and an upper cover, which applies to fixing the expanding card in the expanding slot much firmly through being pressing down the front end of the expanding card by the batten and the upper cover.
2. Description of the Related Art
Referring to
FIG. 1
, it illustrates a three-dimensional dissolution drawing of the expanding card fixing structure
100
in the prior art. There is an expanding card
101
and an expanding slot
102
in this figure. The back end of the expanding card
101
connects a fixing structure
103
with a shape of reverse L to directly lock in the computer apparatus
105
through screw
104
. The expanding slot
102
is in the motherboard
201
of the computer apparatus
105
to install the expanding card
101
and expand the function of the computer apparatus
105
.
Next, referring to
FIG. 2
, it illustrates that the expanding card
101
is directly inserted into the expanding slot
102
and locking the fixing structure
103
with a shape of reverse L in the back end of the expanding card
101
in the case
106
of the computer apparatus
105
through a screw
104
.
In the foregoing expanding card fixing structure
100
, the length of the expanding card
101
is usually longer than the length of the expanding slot
102
; and it will lead to signal transmission error because of the gravity drooping the front end of the expanding card
101
and the expanding card
101
being unable to tightly connecting the computer apparatus
105
through the expanding slot
102
.
In order to lock the expanding card
101
in the expanding slot
102
much firmly, referring to
FIG. 3
, in the advance prior art, the function is still reserved that locking the back end of the expanding card
101
through the screw
104
. Besides, this prior art further sets a slot
200
in the front of the expanding card
101
in order to make the front of the expanding card
101
sliding into the slot
200
. It can strengthen the connection between the expanding card
101
and the expanding slot
102
through simultaneously fixing the front end and the back end of the expanding card
101
However, by the appearance of the computer apparatus
105
being getting mini, the expanding card
101
is not only direct inserting into the expanding slot
102
upright but also through a conversion interface
301
as shown in FIG.
4
.
FIG. 4-1
is enlargement drawing of the conversion interface
301
in
FIG. 4
, there are two connecting faces
504
and
505
in the conversion apparatus and they can bend to the vertical shape through a connecting cable
510
that connects between the two connecting faces
504
and
505
.
There is a card side
506
and a slot side
507
in each of both connecting faces
504
and
505
. By this, the expanding card
101
can be inserted into the slot side
507
of the conversion apparatus
301
and the card side
506
of the conversion apparatus
301
is either inserted into the expanding slot
102
to lay the expanding card
101
horizontally in the motherboard
201
of the computer apparatus
105
for avoiding the occupied much space that the expanding card
101
sets upright in the motherboard
201
of the computer apparatus
105
.
Referring to
FIG. 4
, the front and back end of the expanding card
101
are fixed separately through the slot
200
and the screw
104
, and the expanding card
101
lays horizontally in the motherboard
201
of the computer apparatus
105
. It seems that the defects of locking the expanding card
101
only through screw
104
and occupied space that the expanding card
101
sets upright in the motherboard
201
of the computer apparatus
105
is solved. But in practically plug and pull the expanding card
101
, such design of the slot
200
is still inconvenient
In the
FIG. 4
, It's obvious to see that the case
106
of the computer apparatus
105
being unable to avoid separating the passage that the expanding card
101
slides into the expanding slot
102
. The better way is to remove a side
401
of the case
106
corresponding to the expanding card
101
sliding to the slot
200
, as shown in FIG.
5
. But the process seems complicate with simply plugging and pulling the expanding card
101
.
According to the foregoing defects, the invention discloses an expanding card fixing structure for easy plugging and pulling the expanding card at the expanding slot.
SUMMARY OF THE INVENTION
The first objective of the invention discloses an expanding card fixing structure for easy plugging and pulling the expanding card at the expanding slot.
The second objective of the invention discloses an expanding card fixing structure for the expanding card laying horizontally in the motherboard of the computer apparatus to solve the defects of unnecessary case space that the expanding card sets upright at the expanding slot in the foregoing art.
For the foregoing objective, this invention disposes an expanding card fixing structure that applies to fixing an expanding card in a computer. Such fixing structure comprises an expanding slot, a conversion apparatus, a base, a batten and an upper cover. The expanding slot vertically sets in a motherboard of the computer apparatus. The conversion apparatus has two connecting faces, and there is a card side and a slot side on each connecting face. The base that can be set computer component like hard disk, CD-ROM and floppy disk storage apparatus is in the computer apparatus and in the front of the expanding slot. The batten can be a shape of
-type or L-type. The both arms of the
-type batten are respectively pivoted on both sides of the base and one arm of the L-type batten connects any side of the base after inserting the expanding card into the slot side of the conversion apparatus and inserting the card side of the conversion apparatus into the expanding slot, we can press down the front end of the expanding card through rotating the arms of
-type or of L-type batten. Then we can fix the expanding card in the expanding slot much firmly through the upper cover to continuously press down the
-type or L-type batten.
