ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention discloses an expanding card fixing structure, especially using a arm inserting into a slot, which applies to clipping the extended batten of the back of the expanding card much firmly to fix the expanding card.
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 case
106
of the computer apparatus
105
through a screw
104
. The expanding slot
102
is in the motherboard
106
of the computer apparatus
105
to install the expanding card
101
and expand the function of the computer apparatus
105
. As shown in the figure, the connector
107
is in the back end of the expanding card
101
to connect the connector
109
of the external apparatus
108
.
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 the screw
104
.
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. 3
to make the expanding card
101
lay horizontally in the motherboard
201
of the computer apparatus
105
. It can avoid the occupied space that the expanding card
101
sets upright in the motherboard
201
of the computer apparatus
105
.
Referring to
FIG. 3
, it illustrates that the front and the back of the expanding card
101
are fixed through a slot
200
and the screw
104
and horizontal laying in the motherboard
201
of the computer apparatus
105
. It seems that the defects of locking the expanding card
101
only through the 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 plugging and pulling the expanding card
101
, such design of fixing with screw
104
is still inconvenient.
In the figure, it's obvious to see that it is necessary to move the computer apparatus
105
to preserve a space for taking apart the screw
104
in order to support enough moving space for the screwdriver
401
. But the process seems complicate with simply plugging and pulling the expanding card
101
According to the foregoing defects, the invention gives up said design about the screw
104
and discloses a fixing structure of an expanding card
101
for easy plugging and pulling the expanding card
101
at the expanding slot
102
.
SUMMARY OF THE INVENTION
The first objective of the invention discloses an expanding card fixing structure for easy plugging and pulling an expanding card at an expanding slot.
The second objective of the invention discloses an expanding card fixing structure for an expanding card laying horizontally in the motherboard of a computer apparatus to solve the defects of moving the computer apparatus to preserve enough moving space for the screwdriver in the foregoing art.
According the above-mentioned objectives, such expanding card fixing structure of the invention comprises an expanding slot, a fixing base and a buckle batten. The expanding slot vertically sets in the motherboard of a computer apparatus. The fixing base is in the back of the computer apparatus and in the back of the expanding slot. Besides, there are at least a first slot and a buckle in the fixing base. And a buckle batten further includes a buckle slot for connecting the fixing base through the buckle and the buckle batten vertically extending at least a first arm corresponding to the first slot. While inserting said expanding card into the expanding slot, an extended batten at the back of the expanding card is simultaneously inserted into the first slot, and then the extended batten clips firmly between the first arm and a side of the first slot through inserting the first arm into the first slot.
There further is a second slot in the fixing base, wherein the first slot and second slot are separated through a slot pillar (or buckle pillar) between the first slot and the second slot. Corresponding to the second slot, the buckle batten further comprises a second arm, to strengthen the connection between the buckle batten and the fixing base through inserting the second arm into the second slot.
Besides, the front of the first arm and the second arm respectively extend a hook, while inserting the first arm and the second arm into the first slot and the second slot, each hook can hook the back of a slot pillar (or buckle pillar) back between the first slot and the second slot. Wherein the first arm, the second arm and the two hooks can be shaped as a whole and elastic metal boards.
