Abstract

The utility model relates to a support component of an external extension card. The support component is applied to an electronic device such as a computer, a server, etc. to fix the external extension card to the electronic device. The support component comprises a supporting frame which is arranged on one side of the external extension card. A clamping groove which is used to clamp one side of the external expansion card is arranged on the supporting frame surface opposite the external extension card. Besides, a locking fin is convexly arranged on one side of the supporting frame and is fixedly supported by a fixing frame. The fixing frame is locked on a casing of the electronic device. Thus, one side of the external expansion card can be fixed on the casing of the electronic device, and the other side of the external expansion card can be clamped by the supporting frame for fixation, so that characteristic impairment of the external expansion card or damage of parts on a printed circuit board which are caused by vibration swaying and loosening of the electronic device in the process of vibration or transportation are effectively avoided.

Description

The supporting frame of external expansion board

[technical field]

The relevant a kind of supporting frame of the utility model, especially refer to a kind ofly need not to use the handling tool (as: turnscrew) can be for the supporting frame of assembling and dismantling easily on an electronic installation (as: server) internal partition, make and see through this supporting frame, at least the other end of the external expansion board of a slice (as: expansion board of pci bus) firmly can be clamped, need not simultaneously to worry that circuit and other electronic component can be sent out the survivor by the facts of short circuit.

[background technology]

Along with constantly weeding out the old and bring forth the new of current information product, especially PC (PC's) is widely used, people are more and more higher for the request for utilization of PC, for promoting the usefulness of PC peripheral device when the data transmission, a kind of perimeter component assembly connecting interface (PeripheralComponent Interconnect that is developed by Intel (Intel), hereinafter to be referred as PCI) bus, promptly become the main product in the market, also representing the slower bus of other specification transfer rate (as: ISA), to fade out gradually, and be replaced by this pci bus.

At present on the motherboard of expansion board in a host computer housing of this pci bus, the external expansion board of the main flow of can saying so, now on the motherboard of general ATX specification, has the PCI expansion slot more than five mostly, and if the expansion slot on this motherboard is many more, promptly represent the expansion capacity of this computer strong more, therefore, the big factory of each science and technology is is promptly constantly researched and developed and is improved expansion board and expansion slot, in the hope of satisfying the demand of society, but on the contrary, on the fixed form for this expansion board, but change few relatively.

In addition, with existing industrial 1U (1U=44.45mm) server, since be subjected to the design height influence of this server, therefore, the inside of this 1U server, except having related electronic components, the main printed circuit board (PCB) (PCB) that still includes, if for making this server strengthen its processing power, generally can be on this motherboard, assemble other a expansion board (as: expansion board of preceding described pci bus) extraly, so as to reaching the purpose that strengthens this server handling ability.

Moreover, see also shown in Figure 1, by employed pci bus expansion board 10 on the general computer, be with the standard fixed carriage 11 (Bracket) on itself end, directly inlay card is on several outputs/input port fixed frame 13 on the host shell 12 back plates, wherein offer a hole 111 on this analog bracket 11, this hole 111 is just corresponding with the hole 131 on these output/input port fixed frames 13, whereby, can see through a screw 14 respectively directly locks at these holes 111, in 131, to make this pci bus expansion board 10 be fixed on these output/input port fixed frame 13 and can not become flexible, simultaneously, can make a side of this pci bus expansion board 10 insert in a horizontal manner in the expansion slot 15 on the printed circuit board (PCB).

Employed pci bus expansion board 10 on present server or the workstation, some is to belong to the long microscler card of length, except utilizing screw 14 directly to lock this output/input port fixed frame 13, still must be at the other end of this pci bus expansion board 10, design another bracing frame or fixed mount (not shown), to support this microscler card, avoid damageeing the characteristic of this pci bus expansion board 10 or the part on the printed circuit board (PCB) because of vibrating or transporting in the process.

But, existing bracing frame or fixed mount design, adopt metal to cooperate screw 14 fixed forms mostly, not only all very time-consuming in assembling and use, take a lot of work, simultaneously, also inconvenient user's operation, therefore, if do not take effective fixed form, to alleviate the inconvenience that the user is brought when changing or increase this pci bus expansion board 10 newly, it certainly will will make the user in the installation process, feel loaded down with trivial details, and then reduce the wish of the new pci bus expansion board 10 of installing, thus, to merciless strike will be caused for the supply market of pci bus expansion board 10.

See it on the other hand, for in response to vast market to the assembling computer demand, the high-tech company not only will keep the fine quality of product, simultaneously, also must improve its assembling speed, therefore, for the lifting of the assembling speed of production line, especially this pci bus expansion board 10 is fixing, also becomes a key factor that improves assembling computer speed of production.
