DETAILED DESCRIPTION
Referring to FIG. 1, one embodiment of a mounting apparatus is configured for securing an expansion card 20, and includes a chassis 40 and a securing member 10 pivotably attached to the chassis 40.
The expansion card 20 may be a sound card, a video card, or a graphics card, or other PCI (Peripheral Component Interconnection) cards, and includes a positioning member 21. The positioning member 21 includes a base portion 211, an insertion portion 212 formed on and extending from an end of the base portion 211, and a support portion 213 bent substantially perpendicularly from an opposite end of the base portion 211.
The chassis 40 is configured to receive electronic devices, such as a motherboard, hard disk drives, expansion cards, and so on, and includes a plate 41 with a slot 42 defined therein. An opening 43 is defined in the plate 41 at one side of the slot 42, and is configured to allow insertion of the support portion 213 of the expansion card 20 therethrough. A clip 413 (shown in FIG. 3) protrudes from an inner surface of the plate 31 at an opposite side of the slot 42. A positioning portion 411 and a pair of tabs 412 are bent substantially perpendicularly out from adjacent edges of the opening 43 on an outer surface of the plate 41. An engaging means, such as a locking hole 4111, is defined in the positioning portion 411, and a pivot hole 4121 is defined in each of the tabs 412.
Referring to FIGS. 1-2, the securing member 10 includes a base portion 15 extending in a first direction, a bent portion 11 bent from an edge of the base portion 15 in a second direction substantially perpendicular to the first direction, a connecting portion 13 extending from an edge of the bent portion 11 in a third direction substantially perpendicular to the second direction and opposite to the first direction, and a locking portion 12 extending from the connecting portion 13 in a fourth direction opposite to the third direction. A shaft 151 is formed on the base portion 15 and is configured to pivotably engage in the pivot holes 4121 of the pivot tabs 412 of the chassis 40. A holding space 14 is defined in the securing member 20 and surrounded by the bent portion 11, the connecting portion 13, and the locking portion 12. A pressing block 111 protrudes from the bent portion 11 towards the locking portion 12. An engaging means, such as a locking block 121, protrudes from a free end of the locking portion 12 towards the bent portion 11 and is configured to engage in the locking hole 4111 of the positioning portion 411 of the chassis 40. An operating piece 16 extends from a joint edge of the locking portion 12 and the connecting portion 13 in a direction opposite to the fourth direction.
Referring also to FIG. 4, to install the expansion card 10, the shaft 151 of the securing member 10 is pivotably engaged in the pivot holes 4121 of the pivot tab 412 of the plate 41, and the securing member 10 is thereby pivotably attached to the outer surface of the plate 41. At this point the shaft 151 is substantially parallel to the positioning portion 411. The securing member 10 is then rotated away from the positioning portion 411 of the plate 41, and positioned in an unlocked position. The insertion portion 212 of the expansion card 20 is inserted in between the clip 413 and the inner surface of the plate 41. The support portion 213 of the expansion card 20 is extended through the opening 43 and positioned on the positioning portion 411 of the plate 41. The slot 42 of the plate 41 is covered by the base portion 211 of the positioning member 21.
Referring also to FIG. 5, the securing member 10 can be rotated from the unlocked position towards the positioning portion 411 of the plate 41. After the locking portion 12 abuts an edge of the positioning portion 411, the operating piece 16 is operated to resiliently deform the locking portion 12 and thereby reshape the holding space 14, so that the securing member 10 can be further rotated towards the positioning portion 411. The support portion 213 and the positioning portion 411 are inserted in the holding space 14 of the securing member 10. When the locking block 121 of the locking portion 12 is aligned with the locking hole 4111 of the positioning portion 411, the locking portion 12 rebounds to engage the locking block 121 in the locking hole 4111. The pressing block 111 of the bent portion 11 presses on the support portion 213 of the expansion card 20. Thus, the expansion card 20 is secured in the chassis 40, and the securing member 10 is positioned in a locked position.
In removing the expansion card 20 from the chassis 40, the operating piece 16 of the securing member 10 is pressed to resiliently deform the locking portion 12 and thereby reshape the holding space 14 until the locking block 121 is disengaged from the locking hole 4111 of the positioning portion 411. The securing member 10 can then be rotated away from the positioning portion 411 from the locked position to the unlocked position. When the positioning portion 411 is disengaged from the holding space 14 of the securing member 10, the expansion card 20 can be removed from the chassis 40.
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.
