External device carrier

The present invention relates to an external device carrier, and more particularly to an external device carrier that can electrically connect a plurality of external devices to the circuit board through the same expansion slot on the circuit board.

Although most of the motherboards currently have a variety of built-in functions, in general, the expansion board (expansion slot) is still provided on the motherboard, so that the user can later increase the function of the host according to his needs.

In general, to expand the new function of the host, it is necessary to plug an external card with a specific function, such as a network card, sound card or image capture card, into the expansion slot on the motherboard to make the external connection The card establishes communication with the processing unit on the motherboard. However, the most common practice at present is that an external card is inserted into an expansion slot, and the expansion slot is extremely inefficient. Even if the transfer card is now transferred, the expansion slot on the motherboard can be electrically connected to the card of multiple external cards at the same time. However, when installing or removing these external cards, the user must First remove the upper part of the main unit Cover, and then insert or remove the external card in a piece by hand; this increases the number of external cards that can be used, but does not have any mechanism to assist in installing or removing the external card, and expands the function of the user. It is really inconvenient.

Therefore, it is necessary to invent a mechanism for assisting external card loading and unloading to improve the aforementioned problems.

One end of the connecting rod is pivotally connected to the fixed frame and rotatable relative to the fixed frame. The lock bar is coupled to the other end of the link and is movably coupled to the tray. When the tray is placed in the accommodating space and the lock bar is connected to the tray, the lock bar can move toward the accommodating space to drive the link to rotate, and the tray is displaced toward the adapter so that the external device is connected to the electrical connector.

According to an embodiment of the present invention, the fixture of the present invention further includes a positioning post, and the tray includes a perforation; when the tray is displaced toward the adapter device, the positioning post is used to pass through the perforation to ensure that the external device is connected to the electric device. Connector.

According to an embodiment of the present invention, when the lock lever is connected to the tray and moved toward the accommodating space, the lock lever shifting tray is displaced toward the transfer device, wherein the lock lever is displaced toward the accommodating space and the tray is displaced toward the arranging device. The direction is substantially vertical.

According to an embodiment of the present invention, the external device carrier further includes a latch member, and the tray includes a handle, the handle includes a groove; and the latch member is coupled to the lock bar for penetrating the groove In order to fix the tray in the accommodating space.

According to one embodiment of the present creation, the tray of the present invention includes a handle for facilitating movement of the tray.

According to an embodiment of the present invention, the external device carrier of the present invention further includes a heat dissipating device; the heat dissipating device is connected to the fixing frame for cooling the external device.

According to an embodiment of the present invention, the external device carrier of the present invention further comprises an elastic component; one end of the elastic component is connected to the fixing frame, and the other end is connected with the locking bar; and the elastic component is used to provide a spring force of the locking bar. When the external device is not connected to the electrical connector, the tray is displaced in the direction of the link by the elastic force.

According to an embodiment of the present creation, the creation The fixing frame further includes a shaft; the connecting rod is pivotally connected to the shaft, and the shaft can be rotated by the shaft.

Because the creation of this creation is novel, it can provide industrial use, and it has improved efficiency, so it applies for a new patent according to law.

In one embodiment of the present invention, each of the elastic members 80 is coupled to the third wall 13 of the holder 10 at one end and to the respective lock bars 50 at the other end. The elastic member 80 is used to provide the elastic force of each of the lock levers 50. In the specific embodiment of the present invention, the elastic member 80 is a telescopic spring, but the present creation is not limited thereto.

In one embodiment of the present invention, the cover 90 is coupled to the holder 10 for covering the receiving space 17.

Next, please refer to FIG. 5 to FIG. 7 for the operation of the external device carrier of the present invention, and please continue to refer to FIG. 2 .

As shown in FIG. 2 and FIG. 5, when the external device carrier 1 is used, the user does not need to disassemble the upper cover of the main casing (not shown). In the installation, the user only needs to place the external device EX to be placed on the tray 30, and then combine the guiding groove 34 of the tray 30 with the bump 51 of the lock bar 50, and then the tray 30 is directed into the accommodating space 17. The tray 30 is moved closer to the third wall 13 of the holder 10 at this time.

Then, as shown in Figure 6, the user only needs to Moving the lock lever 50 toward the accommodating space 17 (as indicated by an arrow F1), since the inward movement direction of the tray 30 (ie, the direction indicated by F1) has been restricted, when the user puts the lock lever 50 toward the accommodating space When 17 moves to drive the link 40 to rotate, the tray 30 will only be displaced toward the adapter 20 (as indicated by the arrow F2), wherein the link 40 moves in the direction of the accommodation space 17 and the tray 30 toward the adapter The direction of the 20 displacement is substantially vertical. During the movement, in order to enable the external device EX to be accurately connected to the electrical connector 21, the positioning post 15 first passes through the through hole 32 in the tray 30, and then the external device EX is aligned with the electrical connector 21 before being connected. That is, the positioning post 15 has the function of alignment and positioning. After the external device EX is connected to the electrical connector 21, the external device EX can transmit signals to the main circuit board CB through the switching device 20.

As shown in FIG. 7, after the above actions are completed, in order to ensure that the tray 30 can be firmly seated in the accommodating space 17, the user can push the latch member 60 into the recess 331 (shown by arrow F3) on the handle 33. The tray 30 is secured by the latch 60 so as to secure the tray 30 in the accommodating space 17.

As shown in FIG. 6 , when the user wants to replace the external device EX, the user only needs to pull the lock lever 50 outwardly of the accommodating space 17 to drive the links 40 to rotate toward the third wall 13 , and the tray 30 will be Moving in the direction of the third wall 13 under the rotation of the connecting rod 40, and making the external device EX and the electric device The connectors 21 are separated. Once the external device EX and the electrical connector 21 are no longer connected, the restoring force of the elastic member 80 causes the tray 30 to be displaced toward the link 40, thereby allowing the user to self-load the tray 30 in a more labor-saving and convenient manner. The accommodating space 17 is taken out.

According to the above description, the external device carrier 1 of the present invention can not only electrically connect the plurality of external devices EX to the main circuit board CB through the same expansion slot ES, but also improve the efficiency of the expansion slot ES, and can also be used by the drawer. The design allows the user to install or disassemble the external device EX without removing the upper cover of the main unit casing, which saves time during installation or disassembly.

In summary, this creation shows its characteristics different from conventional technology in terms of purpose, means and efficacy. It is to be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the claims is intended to be limited by the scope of the claims.
