DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIGS. 1 to 3, a mounting apparatus in accordance with an embodiment is configured for securing an expansion card 100 and includes a chassis 10 (only a part is shown), and a mounting tray 20. The expansion cards 100 may be, for example, sound cards, video cards, graphics cards, or other peripheral component interconnection cards.
The chassis 10 includes a bottom plate 11, a side plate 13 connected to a long edge of the bottom plate 11, a front plate 14 connected to a first short edge of the bottom plate 11, and a rear plate 15 connected to a second short edge of the bottom plate 11. Two retaining holes 112 are defined in the bottom plate 11, and a motherboard 110 is attached to the bottom plate 11. In one embodiment, the bottom plate 11 is substantially perpendicular to the side plate 13 and the front plate 14, and the front plate 14 is parallel to the rear plate 15.
A front plate hole 141 is defined in the front plate 14. A first securing member 30 is mounted between the front plate 14 and the bottom plate 11.
Referring to FIG. 2, the first securing member 30 includes a main body 31, two bottom pieces 33 connected to two adjacent bottom edges of the main body 31, and a top piece 35 connected to an upper edge of the main body 31. A first clipping slot 311 is defined in the main body 31, and two blocks 313 are connected to two longer opposite edges of the first clipping slot 311. In one embodiment, the first clipping slot 311 is longitudinally defined in the center of the main body 31. A nick 315 extends from a long edge of the first clipping slot 311, to form a first stopper portion 316 thereon. A fixing hole 331 is defined in each bottom piece 33, corresponding to the two retaining holes 112. A mounting hole 351 is defined in the top piece 35, corresponding to the front plate hole 141.
Referring to FIG. 1, a number of expansion slots 151 is defined in the rear plate 15, adjacent to the side plate 13. A second securing member 40 can be received in an expansion slot 151. Two opposite flanges 41 extend from one side of the second securing member 40, and a second clipping slot 43 is defined between the two opposite flanges 41. A second stopper portion 316 is disposed on an upper edge of the second securing member 40.
Referring to FIG. 3, six posts 21 (shown in FIG. 1), configured to secure the expansion card 100, are disposed on one side of the mounting tray 20. Two through holes 23 are respectively defined in two top corners of the mounting tray 20. Each through hole 23 and a fixing member 70 can secure a rotating member 50 to the tray 20. The rotating member 50 includes a securing portion 51 and an operating portion 53 extended from the securing portion 51. A sliding slot 511 and a pivot hole 513 are defined in the securing portion 51. In one embodiment, the sliding slot 511 is an arc. A hook 515 is located on one side of the securing portion 51, configured for engaging with the first stopper portion 316 or the second stopper portion 316, to prevent the rotating member 50 from rotating. A clipping portion 531 protrudes on a side of the operating portion 53. A clipping hole 25, configured for accommodating the clipping portion 531, is defined in the mounting tray 20. A tab 27 adjacent to the through hole 23 extends from the mounting tray 20 and is configured for sliding in the sliding slot 511.
Referring to FIGS. 4-7, in assembly, the first securing member 30 is placed on the bottom plate 11 and attached to the front plate 14. The front plate hole 141 is aligned with the mounting hole 351, and a first fastening member 90 is inserted into the front plate hole 141 and the mounting hole 351, to secure the top piece 35 to the front plate 14. The fixing hole 331 of the bottom piece 33 is aligned with the retaining hole 112 of the bottom plate 11. A second fastening member 90 is inserted into the fixing hole 331 and the retaining hole 112, to mount the bottom piece 33 to the bottom plate 11. The second securing member 40 is clipped into the expansion slot 151.
Two resilient components 60 are respectively attached on two through holes 23 of the mounting tray 20. Each rotating member 50 is attached to each resilient component 60. The through hole 23 of the mounting tray 20 is aligned with the pivot hole 513 of the rotating member 50, and the fixing member 70 is screwed into the pivot hole 513, the resilient component 60 and the through hole 23. Thus, the rotating member 50 is secured to the mounting tray 20. The expansion card 100 is secured on the mounting tray 20 by a number of screws 80.
The rotating member 50 can be rotated between a first state and a second state. In the first state (shown in FIG. 4), the rotating member 50 is vertically located on the mounting tray 20, the resilient component 60 is released, and the tab 27 is received in sliding slot 511, adjacent a first end of the sliding slot 511. The first end of the sliding slot 511 is near to the hook 515. The clipping portion 531 of the rotating member 50 is disengaged with the clipping hole 25 of the mounting tray 20. In the second state (shown in FIGS. 5-6, the rotating member 50 is horizontally located on the mounting tray 20, and the resilient component 60 is elastically deformed. The tab 27 is received in a second end away from the first end of the sliding slot 511, and the clipping portion 531 of the rotating member 50 is engaged with the clipping hole 25 of the mounting tray 20.
The two rotating members 50 are rotated to the first state, by urging the operating portion 53 of the two rotating member 50. The mounting tray 20 with the rotating member 50 and the expansion card 100 is located between the front plate 14 and the rear plate 15. A first edge of the mounting tray 20 is clipped into the first clipping slot 311 of the first securing member 30, and a second opposite edge of the mounting tray 20 is clipped into the second clipping slot 43. The two rotating member 50 are rotated to the second state, by urging the operating portion 53 of the two rotating member 50. The hook 515 of a first rotating member 50 is engaged with the first stopper portion 316, to prevent the one rotating member 50 from further rotating. The hook 515 of a second rotating member 50 is engaged with the second stopper portion 316, to prevent the other rotating member 50 from further rotating.
In disassembly, the operating portion 53 of the rotating member 50 is rotated in the first state, by urging the operating portion 53 of the rotating member 50. The operating portion 53 is carried in a direction away from the bottom plate 11, and the first and second edges of the mounting tray 20 are respectively disengaged from the first clipping slot 311 and second clipping slot 43. Thus, the mounting tray 20 with the expansion card 100 can be removed from the chassis 10.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
