Multiple expansion card fixing device and system host with multiple expansion card fixing devices

The invention relates to a fixing device, in particular to a plurality of expansion card fixing devices arranged on a wind deflector and a system host having a plurality of expansion card fixing devices.

The development of the computer information industry has brought a wide range of applications for computers. In order to provide more functions, external hardware such as expansion cards with different specific functions are generally added inside the computer. A typical computer system usually has expansion cards with different functions, such as a graphics acceleration display card, a video card, a network card, a sound card, a graphics card, a disk array control card, etc., and is provided on a motherboard of a computer system. Multiple expansion slots. In the prior art, when the expansion card is installed in the expansion slot on the motherboard, the head end of the expansion card (the side that is exposed outside the computer case and some of the expansion cards provide the connection port) is locked to the computer. The rear panel of the case secures the expansion card.

However, for a special computer system such as an industrial computer or a server, since some expansion cards of a long length are installed, if only the head end of the fixed expansion card is fixed, the other end (tail end) is often suspended. Under such a structure, when the servo host is in operation, vibration occurs due to the cooling fan of the computer system, and the excessive length of the expansion card causes a cantilever beam effect at the tail end, which is likely to cause expansion after long-term operation. The card is damaged.

The current practice is that the wind deflector is near the end of the expansion card and has a top-down buckle cover that covers the end of the expansion card to fix the end of the expansion card. However, at present, only one expansion card can be fixed in this way. If the second expansion card is located above the original expansion card, such a fixing method will not be applicable, that is, such a fixed structure cannot install the second expansion card. .

In view of the above, the present invention provides a plurality of expansion card fixing devices for a wind deflector and a system host having a plurality of expansion card fixing devices to solve the above problems.

As described above, the sliding seat 1 can be slid on the base 2 in the second direction L ₂ , and with the sliding stroke, at least one clamping groove is disposed on the sliding seat 1 , and the clamping groove is also along the first The two directions L ₂ extend. In the embodiment, the sliding seat 1 includes a first clamping slot 11 and a second clamping slot 12, and the first clamping slot 11 and the second clamping slot 12 extend along the second direction L ₂ . The horizontal grooves have an opening 111 and an opening 121, respectively. Specifically, the first clamping groove 11 and the second clamping groove 12 are arranged along the first direction L ₁ and are arranged in parallel with each other. Such a structure enables the sliding seat 1 to simultaneously fix the tails of the two expansion cards. End (detailed later).

Since the plurality of expansion card fixing devices 100 are disposed on the air flow path 31 of the air deflector 3, the air flow path 31 of the air deflector 3 has an electronic component that guides the heat dissipation airflow to the outlet of the air flow channel 31 (as in the present invention) The expansion card is disposed to dissipate heat. Therefore, when the plurality of expansion card fixing devices 100 are disposed on the air guiding plate 3, in order to maintain the flow rate of the airflow of the airflow path 31, the base 2 of the plurality of expansion card fixing devices 100 and the sliding The seat 1 can have a plurality of transparent openings 14 (Fig. 3) and openings 24 (Fig. 4) to provide passages through which air flows, the airflow directions L of the openings 14, 24 and the air flow passage 31. ₃ same direction.

As shown in Figures 1, 4, and 5, the air deflector 3 is disposed in a system host 400, which may be an industrial computer or a server. At least one expansion card is installed in the system host 400, and in the embodiment, two long expansion cards are disposed on the top, and the first expansion card 200 and the second expansion card 300 are respectively expansion card 200 and a second expansion card 300 L ₁ is disposed adjacent and parallel to each other along a first direction placement. The first expansion card 200 and the rear end 201 of the second expansion card 300 and the rear end 301 are correspondingly located at the air flow channel 31, and the first clamping slot 11 and the second clamping slot 12 of the mobile housing 1 respectively correspond to the first The tail end 201 of the expansion card 200 and the tail end 301 of the second expansion card 300.

In Fig. 4, the slide base 1 is disposed at the unlocking position P1 on the base 2, so that the first expansion card 200 and/or a second expansion card 300 can be freely mounted. When the sliding seat 1 is slid from the unlocking position P1 of FIG. 4 to the locking position P2 of FIG. 5, the tail end 201 of the first expansion card 200 and the tail end 301 of the second expansion card 300 are respectively from the first clamp. The opening 111 of the holding groove 11 and the opening 121 of the second holding groove 12 are moved into the first holding groove 11 and the second holding groove 12.

As shown in FIG. 3, the openings 111 and 121 are slightly larger than the widths of the first clamping groove 11 and the second clamping groove 12, so that the tail ends 201 and 301 can be easily moved in, but not limited thereto.

After being disposed in the locking position P2 of FIG. 5, the first clamping slot 11 and the second clamping slot 12 respectively limit the tail end 201 of the first expansion card 200 and the tail end 301 of the second expansion card 300, so that It cannot move along the first direction L ₁ , thereby providing the structural stability of the tail end of the elongated expansion card after installation.
