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” exemplary embodiment in this disclosure are not necessarily to the same exemplary embodiment, and such references mean at least one.
Referring to FIGS. 1 and 2, an electronic device enclosure in accordance with an exemplary embodiment includes a computer case 10, a mounting tray 30, and a fastening member 50 for securing the mounting tray 30 to the computer case 10. In one exemplary embodiment, the mounting tray 30 is used to secure a plurality of expansion cards (not shown).
The computer case 10 includes a bottom plate 11, a first side plate 13, a second side plate 14, a front plate 15 connected to the first side plate 13 and the second side plate 14, and a cover 17 for covering the computer case 10. In one exemplary embodiment, the first side plate 13 and the second side plate 14 are substantially parallel to each other and perpendicular to the bottom plate 11, and the front plate 15 is substantially perpendicular to the bottom plate 11.
A retaining member 151, adjacent to the first side plate 13, extends from the front plate 15. A retaining slot 1511 is defined in the retaining member 151. In one exemplary embodiment, the retaining member 151 is substantially parallel to the first side plate 13. A positioning slot 153, an opening 155 and a sliding groove 157 are defined in the front plate 15 and are located between the retaining member 151 and the first side plate 13.
The mounting tray 30 includes a front panel 31, a side panel 33 connected to the front panel 31, and a top panel 35 connected to the front panel 31 and the side panel 33. A securing portion 311, connected to the front panel 31, includes an extending piece 3112, and a securing piece 3114 attached to the extending piece 3112. A securing hole 3115 is defined in the securing piece 3114. In one exemplary embodiment, the securing piece 3114 is substantially perpendicular to the extending piece 3112.
Referring to FIG. 3, the fastening member 50 includes a main body 51, a clipping plate 53, a positioning plate 55, and a latching plate 57. A mounting hole 511, corresponding to the securing hole 3115, is defined in the main body 51. A through hole 531 is defined in the clipping plate 53, and a clipping piece 5311 is connected to a first edge of the through hole 531. In one exemplary embodiment, the clipping piece 5311 is slanted.
A catch 551 is located on a free end of the positioning plate 55. In one exemplary embodiment, the catch 551 is arcuate and for being received to slide in the sliding groove 157 of the front plate 15. The latching plate 57 includes a first section 571, and a second section 573 connected to the first section 571. A protruding block 5711 is located on the center of the first section 571, for abutting the extending piece 3112 of the securing portion 311. An inserting portion 5731 vertically extends from the second section 573. In one exemplary embodiment, the inserting portion 5731 is elastic and L-shaped.
Referring to the FIGS. 4-5, in assembly, the positioning plate 55 and the latching plate 57 of the fastening member 50 are facing the front plate 15, and the clipping plate 53 abuts the retaining member 151. The fastening member 50 is moved towards the front plate 15, and the first section 571 of the latching plate 57 is engaged into the positioning slot 153. The second section 573 of the latching plate 57 is located adjacent the front plate 15 inside of the computer case 10, and the catch 551 of the positioning plate 55 abuts the front plate 15. The fastening member 50 is rotated to move the inserting portion 5731, and the inserting portion 5731 is deformed to pass through the opening 155 of the front plate 15. Then, the inserting portion 5731 is released to rebound and is located outside of the computer case 10. The main body 51 of the fastening member 50 is pushed, and the catch 551 is engaged into the sliding groove 157. The clipping piece 5311 of the clipping plate 53 is engaged in the retaining slot 1511 of the retaining member 151. Therefore, the fastening member 50 is secured to the front plate 15.
The mounting tray 30 is placed above the bottom plate 11, and the front panel 31 of the mounting tray 30 abuts the front plate 15. The extending piece 3112 of the securing portion 311 covers the first section 571 of the fastening member 50, and the securing piece 3114 abuts the main body 51 of the fastening member 50. The securing hole 3115 of the securing piece 3114 is aligned with the mounting hole 511 of the main body 51. A nut 60 abuts the inside of the main body 51, and a mounting component 70 is passed through the securing hole 3115 and the mounting hole 511, for being engaged into the nut 60. Thus, the mounting tray 30 is secured to the front plate 15. Then, the protruding block 5711 abuts the bottom of the extending piece 3112.
In disassembly, the mounting component 70 and the nut 60 is removed from the fastening member 50 and the front plate 15. The inserting portion 573 is elastically deformed for being disengaged from the opening 155. The fastening member 50 is moved upwards, the latching plate 57 is removed from the positioning slot 153, and the catch 551 of the positioning plate 55 is slid in the sliding groove 157 of the front plate 15. The fastening member 50 is moved further, so the catch 551 is disengaged from the sliding groove 157, and the clipping piece 5311 is removed from the retaining slot 1511. The fastening member 50 is removed from the front plate 15. Therefore, the mounting tray 30 is disengaged from the computer case 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.
