## Background
BACKGROUND
1. Technical Field
The present disclosure relates to an enclosure of an electronic device.
2. Description of Related Art
Generally speaking, a common electronic device, such as a computer or a server, needs an alternating current (AC) supply unit. The AC supply unit includes an enclosure, and an electrical outlet mounted on the enclosure. The electrical outlet includes a plurality of wires and an electromagnetic interference absorbing magnetic ring fitting about some of the wires.

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 FIG. 1, an exemplary embodiment of an enclosure of an electronic device includes an upper shell 10, a lower shell 20, an electrical outlet 30, and a plurality of fixing members 40. In this embodiment, the electronic device is an alternating current (AC) supply unit.
The upper shell 10 includes an upper plate 12 and a side plate 14 perpendicularly extending down from a first side of the upper plate 12. The upper plate 12 defines four through holes 120. One of the four through holes 120 is adjacent to the first side and a first end of the upper plate 12 perpendicular to the first side. The other three through holes 120 are located at a second side of the upper plate 12 opposite to the first side. A first side of the side plate 14 defines a through hole 140 therein, adjacent to the first side and a second end of the upper plate 12 opposite to the first end. A tongue 142 perpendicularly extends from an edge of the side plate, adjacent to the through hole 140.
The lower shell 20 includes a lower plate 22, a front plate 24 perpendicularly extending up from a front end of the lower plate 22, a rear plate 26 perpendicularly extending up from a rear end of the lower plate 22, and a side plate 28 extending up from a first side of the lower plate 22. A circuit board 220 is mounted on the lower plate 22. The circuit board 220 including many electronic elements of the AC supply unit. The front plate 24 defines a rectangle-shaped opening 240, a cable channel 242 adjacent to a second side of the lower plate 22 opposite to the first side and communicating with the opening 240, a plurality of ventilation holes 244 opposite to the cable channel 242 relative to the opening 240. A mounting piece 246 perpendicularly extends from the front plate 24 towards the rear plate 26, adjacent to the cable channel 242. The mounting piece 246 is above the cable channel 242 and defines a fixing hole 248. A mounting piece 260 perpendicularly extends from a top of the rear plate 26. The mounting piece 260 defines a fixing hole 262. A mounting piece 280 perpendicularly extends from a top of the side plate 28. The mounting piece 280 includes three protruding portions 282. The protruding portions 282 each define a fixing hole 284.
The electrical outlet 30 includes a connector 32, and a plurality of wires. The connector 32 includes a plurality of pins electrically connected to the wires. The pins include a live pin, a neutral pin, and a ground pin. The wires include a live wire 320, a neutral wire 322, a ground wire 324, correspondingly electrically connected to the live pin, the neutral pin, and the ground pin. The live wire 320, neutral wire 322, and ground wire 324 each connect to a conductive ring 326. An electromagnetic interference absorbing magnetic ring 34 fits about the live wire 320 and the neutral wire 322.
In this embodiment, each fixing member 40 is a screw.
Referring to FIG. 2, in assembly, the live wire 320, neutral wire 322, ground wire 324 of the electrical outlet 30 pass through the cable channel 242 and extend through the opening 240 to enter into the lower shell 20, and are electrically connected to the circuit board 220 by the rings 326. Thus, the electromagnetic interference absorbing magnetic rings 34 is located in the lower shell 20 and not easily scratched. The connector 32 is exposed from the opening 240 and covers the opening 240. The upper shell 10 covers the lower shell 20, with the tongue 142 covering the cable channel 242, the through hole 140 aligning with the fixing hole 248, the through hole 120 adjacent to the first side and the first end of the upper plate 12 aligning with the fixing hole 262, and the three through holes 120 locating at the second side of the upper plate 12 aligning with the three fixing holes 284. The fixing members 40 extend through the through hole 140 and the four through holes 120 to lock in the fixing hole 248, the fixing hole 262, and the three fixing holes 284, thereby, the upper shell 10 is mounted on the lower shell 20.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, 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.
