DETAILED DESCRIPTION

Embodiments of the present disclosure are described with reference to the accompanying drawings.

Referring to FIGS. 1-3, an electronic device 1 in accordance with an exemplary embodiment is illustrated. The electronic device 1 includes a housing 10, a circuit board 20 accommodated in the housing 10, a port shield 30, and two fasteners 40 securing the port shield 30 to the housing 10. The circuit board 20 includes a number of I/O ports 23 mounted thereon. In the embodiment, the electronic device 1 is an multi-media player, and the I/O ports 23 include four ports for respectively connecting with a microphone, an earphone, a universal serial bus (USB) device, and a power device.

The housing 10 includes a cover 11 and a base 12 coupled with the cover 11. Two first positioning posts 13 protrude from the cover 11 toward the base 12, and each defines a first positioning hole 130. Two second positioning posts 15 protrude from the base 12 toward the cover 11, and each defines a second positioning hole 150 substantially aligned with the first positioning hole 130. The second positioning hole 150 is a stepped through hole. The base 12 defines a recess 14 in one side and a number of openings 140 in the recess 14 for exposing the I/O ports 23. Thus, the I/O ports 23 are accessible through the openings 140 from an exterior of the electronic device 1.

The circuit board 20 includes a first surface 21 facing the cover 11 and an opposite, second surface 22. The I/O ports 23 are mounted on the first surface 21. The circuit board 20 defines three latching holes 24, two positioning holes 25, and two through holes 26. The latching holes 24, the positioning holes 25, and the through holes 26 extend through both of the first surface 21 and the second surface 22.

Referring also to FIG. 4, the port shield 30 includes a main body 31 and two fastening portions 32 located at one side of the housing portion 31. The housing portion 31 includes two hooks 310 and two positioning posts 312, and defines a number of receiving spaces 314 for receiving and positioning the I/O ports 23 therein. After assembling the port shield 30 to the circuit board 20, the positioning posts 312 are fitted in the positioning holes 25, and the hooks 310 latch with the latching holes 25. Then the I/O ports 23 are housed in the receiving spaces 314 of the port shield 30.

Referring also to FIG. 5, each fastening portion 32 defines a first cavity 322 retaining a distal end of the first positioning post 13 and a second cavity 324 retaining a distal end of the second positioning post 15. The fastening portion 32 further includes a middle plate 326 between the first cavity 322 and the second cavity 324. The middle plate 326 defines a guide hole 320 communicating with both the first cavity 322 and the second cavity 324. A diameter of the guide hole 320 is less than that of the first positioning post 13 and the second positioning posts 15.

The fastener 40 includes a head 41 and a shank 42 connected to the shank 41. The diameter of the shank 32 is less than the diameter of the shank 31.

In assembly, the shank 42 of the fastener 40 extends in sequence through the second positioning hole 150 of the base 12 and the guide hole 320, till being screwed into the first positioning hole 130, which secures the port shield 30 to the cover 11. Thus, I/O ports 23 are positioned within the receiving spaces 314 of the port shield 30, thereby preventing the I/O ports 23 from becoming loose and detaching from the circuit board 20.

While various embodiments have been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
