Description

Expansion card fixer

[technical field]

The utility model is about a kind of expansion card fixer, be meant especially a kind of easy to loading and unloading, the expansion card fixer with good retention effect.

[background technology]

The function limitation of most personal computers, can be installed some usually and strengthen its extra function as expansion boards such as sound card, graphics acceleration cards for cooperating the more and more stronger functional requirement of computing machine now in the configuration of motherboard itself in main frame.

Existing expansion board is directly installed in the expansion slot of computer main frame panel usually.The shortcoming of this kind structure is: the expansion slot on the motherboard takies the big quantity space of motherboard, and along with current computer towards short and small frivolous trend development, expansion board is because of being subjected to the space constraint of computer case, can not directly be inserted on the motherboard in the conventional mode more, in order to address this problem, industry adopts the less adapter of a size to be plugged on the motherboard earlier, again expansion board is inserted this adapter from the direction that is parallel to motherboard, thereby solve the problem that is subjected to the computer case space constraint.

Announce the 5th as United States Patent (USP), 835, the expansion board fixed form that discloses for No. 346, comprise a pedestal and a top cover, this pedestal vertical and this pedestal bottom plate by one cut apart the wall separated into two parts, one motherboard horizontal direction is installed on the base plate of this pedestal, and a transition card is cut apart wall near this and electrically connected perpendicular to this motherboard installation and by a connector and this motherboard.Device has a series of horizontal Extend card connectors on this transition card, can be used to the device expansion board.During installation, at first expansion board is inserted in the Extend card connector corresponding on this transition card, a side that connects with peripherals on the expansion board is inserted in the corresponding storage tank of this computer base one side then, and locks by screw.But, this adapter directly inserts in this motherboard, these expansion boards then are to be plugged in to be directly fixed on plate behind the computer base behind this adapter, in the mobile computer process or computing machine when being subjected to accidental shock, all easily produce between transition card and motherboard and in expansion board and the transition card and become flexible, and influence its normal operation.

[summary of the invention]

It is a kind of simple in structure, easy to loading and unloading that the purpose of this utility model is to provide, and the good expansion card fixer of retention effect.

The utility model is achieved through the following technical solutions: the utility model expansion card fixer, and be used for fixing expansion and be stuck in the casing, comprise that one is fixed with fixed mount, a clamping device and a computer base of an adapter and an expansion board.This fixed mount comprises a top board, side plate and a back plate, and this side plate is provided with a pair of clamping part, a pressure-bearing portion and a stopper section, and this back plate is provided with one and expands draw-in groove.This switching card device and which is provided with an Extend card connector on this side plate.This clamping device comprises a pulling part, a pressure section and an ejection part.This computer base comprises a buckle slot, is used for the clamping part of ccontaining this fixed mount side plate, and wherein this clamping device is fixed on the sidewall of this computer base, and can rotate freely around this computer base.Wherein, when pushing the pulling part of this clamping device, the pressure section of this clamping device compresses the pressure-bearing portion of this fixed mount, then this fixed mount moves down, and its clamping part is snapped in the buckle slot of this computer base, promptly finishes assembling, when lifting the pulling part of this clamping device, the ejection part of this clamping device withstands the stopper section of this fixed mount, and then the clamping part of this fixed mount breaks away from this buckle slot, promptly finishes dismounting.

Advantage of the present utility model is: simple in structure, easy to loading and unloading, and it is loosening to avoid expansion board to take place in the computing machine moving process or when being subjected to accidental shock, thus can keep this expansion board to go on well.
