1. Technical Field
The present disclosure relates to a portable electronic device, and more particularly to a Universal Serial Bus (USB) device.
2. Description of Related Art
A USB device, for example, a wireless network card, a USB flash disk, connects with an electronic product (such as a personal computer) to transmit data and signals by a USB plug of the USB device. Generally, the USB plug is secured by a housing connected to a main body of the USB device. The housing includes a top cover and a bottom cover. The USB plug is fixed between the top cover and the bottom cover. However, during inserting or removing the USB plug into or from the electronic product, a junction between the top cover and the bottom cover tends to be damaged easily due to excessive load. How to design the USB device having a strengthened housing to secure the USB plug is a question for discussion.
Therefore, a need exists in the industry to overcome the described limitations.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
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.

The main body 20 comprises a first cover 22 and a second cover 24 cooperatively defining a cavity for receiving the PCB 30. The first cover 22 defines a fixing hole 220 for securing the hinge assembly 40. The hinge assembly 40 comprises a hinge portion 42 and a sleeve portion 44 rotatably engaging with each other. The hinge portion 42 is fixed in the fixing hole 220. The sleeve portion 44 is fixed in the USB connector 60. Therefore, the USB connector 60 is capable of rotating relative to the main body 20

The pair of side walls 6680, the front wall 6682, the back wall 6684, the top wall 6686 and the bottom wall 6688 cooperatively form an integrally formed enclosure 669 enclosing the receiving room 660 and having the first opening 663 formed at front of the enclosure 669 and the second opening 664 formed at top of the enclosure 669.
The shell 66 further comprises a containing portion 662, a pair of positioning portions 665, a latching block 666 and a first flange 667. The containing portion 662 is configured at a corner of the shell 66 and close to the back wall 6684. In assembly, the sleeve portion 44 of the hinge assembly 40 is fixed in the containing portion 662. The pair of positioning portions 665 are close to the second opening 664 and respectively inwardly protrude from the pair of side walls 6680 toward the receiving room 660. One of the pair of positioning portions 665 is connected between one of the side walls 6680 and the containing portion 662. Each of the positioning portions 665 defines a positioning hole 6650. In this embodiment, the pair of positioning portions 665 are parallel with the bottom wall 6688. The latching block 666 inwardly protrudes from the bottom wall 6688. The first flange 667 outwardly protrudes from one of the pair of side walls 6680 and is opposite to the containing portion 662 and close to the back wall 6684. An end surface 6672 of the first flange 667 is half-annular shaped.
The cover 64 comprises a pair of positioning posts 642 respectively opposite to the pair of positioning holes 6650. In assembly, the cover 64 shields the second opening 664 of the shell 66. The cover 64 is positioned to the shell 66 by engagements between the pair of positioning posts 642 and the pair of positioning holes 6650. The cover 64 further comprises one or more first positioning blocks 646 and a second flange 644. The first positioning blocks 646 are close to one edge of the cover 64 and arranged on a same row. The second flange 644 has a same structure with the first flange 667 of the shell 66 and is used to engage with the first flange 667 to cooperatively form an export for the wire group 68. That is, the first flange 667 and the second flange 644 cooperatively receive a middle section of the wire group 68. In assembly, the first flange 667 and the second flange 644 are connected to the main body 20 to communicate the receiving room 660 to inner of the main body 20, therefore, the wire group 68 can be inserted into the main body 20 to be connected to the PCB 30.
The USB plug 62 defines a latching groove 620 and comprises one or more second positioning blocks 622. The latching groove 620 and the second positioning blocks 622 are respectively located two opposite surfaces of the USB plug 62.

The sleeve portion 44 is fixed into the containing portion 662, and the hinge portion 42 is fixed in the fixing hole 220 of the main body 20, to rotatably install the USB connector 60 to the main body 20. The wire group 68 is inserted into the main body 20 to be connected to the PCB 30.
The USB connector 60 has a strengthened structure at the first opening 662 of the shell 66, due to the top wall 6686, the pair of side walls 6680, the bottom wall 6688 and the front wall 6682 being integrally formed with each other and cooperatively defining the first opening 663. Therefore, the shell 66 can bear a high torsional force and is not easily to be damaged.
