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. 1-2, a mounting apparatus in accordance with an embodiment is configured for securing a plurality of PCI cards 50 each with a pin portion 52. The mounting apparatus includes a chassis 70, a locking mechanism 30, and a plurality of securing plates 60.

The chassis 70 includes a bottom wall 72 and a sidewall 71 connected to the bottom wall 72. In one embodiment, the sidewall 71 is substantially perpendicular to the bottom wall 72. A printed circuit board 10, such as a motherboard, is secured to an inner surface of the bottom wall 72. A plurality of PCI connectors 11 is located on the printed circuit board 10 and are capable of receiving the pin portions 52 of the PCI cards 50 to be electronically connected with the printed circuit board 10. The printed circuit board 10 defines two through holes 15. A supporting portion 712 is located on an inner surface of the sidewall 71.

Referring to FIG. 3, the locking mechanism 30 includes a securing member 31 and a plurality of latch members 33 capable of being secured to the securing member 31.

The securing member 31 includes a main portion 311. The main portion 311 extends along a direction and defines two securing holes 3112, corresponding to through holes 15 of the printed circuit board 10. A plurality of blocks 313 is located on the main portion 311. A holding space 3131 is defined between each two adjacent blocks 313, configured for receiving the latch members 33. Two protrusions 3135 are located in each holding spaces 3131 and extend towards each other. A gap 3137 is defined between each protrusion 3135 and the main portion 311.

Each latch member 33 includes a locking portion 331, a first lever 335 and a second lever 337. The locking portion 331 includes a first tab 3311 and a second tab 3313 at each of opposite sides. A securing slot 3315 is defined between the first tab 3311 and the second tab 3313, configured for receiving the protrusion 3135 of the securing member 31. The first tabs 3311 are configured to be inserted into the gaps 3137 of the securing member 31. The first lever 335 has a length greater than that of the second lever 337. A slit 339, defined between the first lever 335 and the second lever 337, receives the PCI card 50.

Each securing plate 60 is secured to one PCI card 50 and is capable of securing the PCI card 50 to the supporting portion 712 of the sidewall 71 of the chassis 70.

Referring to FIGS. 1 and 4, the printed circuit board 10 is fixed on the bottom wall 72 of the chassis 70. The securing member 31 of the locking mechanism 30 is placed on the printed circuit board 10, and the securing holes 3112 of the securing member 31 correspond to the through holes 15 of the printed circuit board 10. Two fasteners (not shown), such as screws, are screwed into the securing holes 3112 and the through holes 15 to secure the securing member 31 to the printed circuit board 10 or the bottom wall 72.

The pin portions 52 of the PCI cards 50 are inserted into the PCI connectors 11 of the printed circuit board 10. The PCI cards 50 are substantially perpendicular to the sidewall 71 of the chassis 70. The securing plates 60 are secured to the support portion 712 of the sidewall 71, and one end of each PCI card 50 is adjacent to the securing member 31. The locking portions 331 of the latch members 33 are inserted into the holding spaces 3131 of the securing member 31 along a first direction substantially perpendicular to the sidewall 71 and the extending direction of the main body 3311. The first tabs 3311 of the securing member 31 are received in gaps 3137 of the securing member 31. The protrusions 3135 of the securing member 31 are received in the securing slots 35 of the latch member 33. The ends of the PCI cards 50 are received in the slits 339 of the latch member 33. Therefore, the PCI cards 50 are secured to the chassis 70.

In removal of the PCI cards 50, the latch members 33 are removed from the securing member 31 along a direction opposite to the first direction, and the PCI cards 50 are disengaged from the slits of the latch members 33. Then, the securing plates 60 are disengaged from the supporting portion 712 of the sidewall 71. The PCI cards 50 can be taken out from the chassis 70.

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.
