DETAILED DESCRIPTION

[0010] 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.

[0011] Referring to FIG. 1, a computer enclosure in accordance with an embodiment includes a chassis 10 and a shielding cover 30 detachably secured to the chassis 10.

[0012] The chassis 10 is capable of accommodating electronic elements therein. The electronic devices, may include, but not limited to, a motherboard, a hard disk drive, a power supply. The chassis 10 includes a rear panel 11. In FIGS. 1, and 3-4 of one embodiment, only the rear panel 11 is shown. A through opening 111 is defined in the rear panel 11. In one embodiment, the through opening 111 is rectangular. The through opening 111 has a first edge 112, a second edge 113, a third edge 114, and a fourth edge 115. In one embodiment, the first edge 112 has a length substantially the same as the second edge 113. The third edge 114 also has a substantially length same to the fourth edge 115, but shorter than the length of the first and second edges 112, 113.

[0013] The shielding cover 30 is removably coupled to the rear panel 11 to cover the through opening 111, so as to improve Electro Magnetic Interference (EMI) shielding of the computer enclosure. In one embodiment, the shielding cover 30 is substantially rectangular. The shielding cover 30 includes a base body 31, a first flange 301, a second flange 302, a third flange 303, and a fourth flange 304. The base body 31 defines a plurality of connector slots. The connector slots are configured to receive connectors. For example, the connectors may be Universal Serial Bus connectors, monitor connectors, mouse connectors, keyboard connectors, etc. In one embodiment, the first flange 301 has a length substantially equal to that of the second flange 302 and the first and second edges 112, 113 of the through opening 11; the third flange 303 has a substantially length equal to that of the fourth flange 304 and the third and fourth edges 114, 115 of the through openings 11. A plurality of clips 35 is located on the first flange 301. The clips 35 and the first flange 301 forms a clamping space capable of receiving the first edge 112 of the through opening 11. A plurality of first protrusions 30111 is located on the first flange 301 and abuts the rear panel 11 when the first edge 112 is held in the clamping space. A plurality of second protrusions 3021 is located on the second flange 302 and engages with the rear panel 11 when the shielding cover 30 is secured to the rear panel 11. The second flange 302 is connected to the base body 31 via a resilient portion 37. In one embodiment, the resilient portion 32 is U-shaped bend. The resilient portion 37 defines a plurality of through slots 373. A plurality of resilient tabs 375 is located on the resilient portion 37, and each tab 375 extends from an edge of the through slot 373. The tabs 375 and the second flange 302 are capable of clipping the second edge 113 of the through opening 111. A plurality of third protrusions 3031 is located on the third flange 303, and a plurality of fourth protrusions 3041 is located on the fourth flange 304. The third and fourth protrusions 3031, 3041 engages with the rear panel 11 when the shielding cover 30 is secured to the rear panel 11.

[0014] Referring also to FIGS. 3-4, in assembly, the first edge 112 of the through opening 111 of the rear panel 11 is received in the between the clips 35 and the first flange 301 of the shielding cover 30. The shielding cover 30 is pivotally rotated about engagement of the shielding cover 30 and the rear panel 11 to insert the resilient portion 37 in the through opening 111, until the positioning tabs 375 abut the second edges 113 of the through opening 111. The shielding cover 30 is further rotated so that the resilient portion 37 and/or the positioning tabs 375 are resiliently deformed because of the engagement with the second edge 113. When the positioning tabs 375 are moved cross the second edge 113, the resilient portion 37 and/or the positioning tabs 375 returns to normal to together with the second flange 302 engage the second edge 113 between the positioning tabs 375 and the second flange 302. The first, second, third, and fourth protrusions 3011, 3021, 3031, 3041 abut on the rear panel 11. Thus, the shielding cover 30 is secured on the rear panel 11 and covers the through opening 111.

[0015] In disassembly, the resilient portion 37 is resiliently deformed to disengage the positioning tabs 375 from the second edge 113, so that the positioning tabs 375 do not block the shielding cover 30 from moving out of the through opening 111. As a result, the shielding cover 30 is disengaged from the second edge 113 of the through opening 111 firstly and then removed from the through opening 111. Thus, the shielding cover 30 is removed from the rear panel 11.

[0016] 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.
