Detailed description of the invention

Refer to Fig. 1-3, in a preferred embodiments of the present utility model, an expansion card fixer 100 is for being connected some expansion boards 10 with a cabinet housing 20. In one embodiment, described expansion board 10 can be sound card, network interface card, video frequency collection card and PCI video card etc. The front end of each expansion board 10 is provided with a connection piece 11.

Described cabinet housing 20 includes one for supporting the support portion 21 of connector 11 of described expansion board 10. Described support portion 21 can be arranged at right cap, left cap, rear door of described cabinet housing 20 etc. In one embodiment, described support portion 21 is arranged on the rear door 23 that cabinet housing 20 is cabinet housing 20, and the both sides of described support portion 21 respectively offer a pivoting hole 211. Described rear door 23 offers two through hole 231, a fixing hole 233 and two and is positioned at the perforate 235 of described fixing hole 233 both sides above described support portion 21. The both sides of the edge of each perforate 235 are extended with a banking stop 2351.

Described expansion card fixer 100 includes a rotation and is fixed on the press part 40 of described cabinet housing 20, all right one way or the other fastener 50 and that is fixed on described press part 40 and can be snapped in the actuator 60 of described fastener 50.

The both sides of described press part 40 are extended with a rotating shaft 41 that is rotatably contained in described pivoting hole 211. Two stators 43 are located on described press part 40 vertically upward, and each stator 43 is tiltedly installed with a clamping part 431.

The fixed block 51 and one that each fastener 50 includes a hollow is connected in the operating portion 53 of described fixed block 51. In one embodiment, described fixed block 51 is roughly curved. One end of described fixed block 51 offers a block button hole 511, and the other end is being provided with lug 513 near operating portion 53 places. The stator 43 of described press part 40 can insert in the fixed block 51 of hollow, and allows described clamping part 431 be snapped in described block button hole 511, and like this, described fastener 50 just can be fixed on described press part 40 by buckle. Certainly, described fastener 50 also can adopt other fixed forms, as the mode of screw locking, riveted joint is fixed on press part 40. In addition, described fastener 50 also can be one-body molded with described press part 40. Described operating portion 53 is roughly square, and can be positioned at through the through hole 231 of described rear door 23 outside of described rear door 23. In the time that described fastener 50 is fixed on described press part 40, operate described operating portion 53 in the outside of described rear door 23, can allow described fastener 50 drive described press part 40 to rotate relative to described cabinet housing 20. In one embodiment, described operating portion 53 also can be other shapes, as, circle, the oval shape that waits handled easily, and described through hole 231 also can carry out corresponding distortion according to the shape of described operating portion 53.

Described actuator 60 includes a body 61, two and is located at the holding division 65 that extend from each 63 lower end, location division respectively the location divisions 63 and two at body 61 two ends. Described body 61 is provided with an installation portion 611. Described installation portion 611 can be through the fixing hole 233 of described rear door 23, to allow described actuator 60 be positioned on described rear door 23. In one embodiment, roughly curved and elastically deformable of described body 61. Each location division 63 can be clamped between two banking stops 2351.

Refer to Fig. 4 and Fig. 5, when assembling, the installation portion of described actuator 60 611 is through the fixing hole 233 of described rear door 23, and each location division 63 is held between two banking stops 2351, to allow actuator 60 be fixed on described rear door 23. The connector of described expansion board 10 11 is placed on described support portion 21. The rotating shaft 41 of described press part 40 is rotated and is contained in described pivoting hole 211, so that described press part 40 is rotated and to be fixed on the support portion 21 of described cabinet housing 20. At this moment, the connector 11 of described expansion board 10 is between described support portion 21 and press part 40. The stator 43 of described press part 40 inserts in the fixed block 51 of hollow, and allows described clamping part 431 be snapped in described block button hole 511, and like this, described fastener 50 just can be fixed on described press part 40 by buckle. Body 61 strains of pressing described actuator 60 and order about described actuator 60, to allow described holding division 65 away from described through hole 231. Like this, the operating portion 53 of described fastener 50 can be positioned at through the through hole of described rear door 23 231 outside of described rear door 23. Described actuator 60 elastic recoverys, and allow described holding division 65 be snapped on described lug 513, like this, can stop described press part 40 to rotate relative to described cabinet housing 20, to allow the connector 11 of described expansion board 10 be held between described support portion 21 and press part 40. At this moment, described expansion card fixer 100 is in a locking position.

Refer to Fig. 6-8, dismounting is when expansion board 10, presses described actuator 60 and body 61 strains of ordering about described actuator 60, to allow described holding division 65 depart from described lug 513. Operate described operating portion 53, and allow described fastener 50 drive described press part 40 to rotate around described rotating shaft 41 together. Like this, described press part 40 can, away from the connector of described expansion board 10 11, like this, can disassemble described expansion board 10.

Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations. For the utility model person of an ordinary skill in the technical field; make without departing from the concept of the premise utility some alternative or obvious modification that are equal to; and performance or purposes identical, all should be considered as belonging to the utility model by the definite scope of patent protection of submitted to claims.
