The third slider 224a and the fourth slider 224b are respectively connected to the first limiting element 226a and the second limiting element 226b. The distance between the first limiting portion 225 and the second limiting portion 226 is approximately less than the depth of the metallic plug 31, thus, an interference fit for limiting the metallic plug 31 is formed. Specifically, the first limiting element 225a and the third limiting element 226a are correspondingly disposed forming the interference fit, wherein FIG. 5c shows the sectional view along line A-A′ when the top cover is engaged with the bottom cover.
The first slider 223a, the second slider 223b, the third slider 224a, and the fourth slider 224b help in limiting the position of the metallic plug 31. The first limiting element 225a and the third limiting element 226a, and the second limiting element 225b and the fourth limiting element 226b cooperate in limiting the position of the metallic plug 31, thus, separation of the USB plug 30 from the body 20 is prevented.
Note that the first limiting portion 225 and the second limiting portion 226 need not be correspondingly disposed, for example, the first limiting portion 225 and the second limiting portion 226 can be separated by a distance. Thus, the number of limiting elements is not limited to two as described, and can also be one or more depending on requirements. Additionally, the number of the limiting elements of the first limiting portion 225 and the second limiting portion 226 can be different.
Furthermore, note that the bottom sliding portion 223 and the top sliding portion 224 can be not connected to the first limiting portion 225 or the second limiting portion 226 and thus, the number of sliders of the top sliding portion 223 and the top sliding portion 224 can be different.
The interference fit of the second limiting portion 226 and the first limiting portion 225 limits the top and the bottom surface of the metallic plug 31 to achieve the limitation. Additionally, it can limit the right and the left sides of the metallic plug 31 to achieve the limitation. For example, the distance between the first limiting element 225a and the second limiting element 226b is approximately less than the width of the metallic plug, to form the interference fit.
Referring to FIG. 4 and FIGS. 5a-5c, the insulating portion 32 comprises a first connector 34, and the first connector 34 comprises a plurality of connector pins 34a (as shown in FIG. 4).

Referring to FIG. 7, the second hook 222a of the bottom cover 22 is engaged with the fourth hook 32b of the insulating portion 32.
FIG. 8 is an external schematic view of an embodiment of the portable electronic device, when the USB plug 30 is in a second position and the top cover 21 is omitted in FIG. 9 to clearly depict the USB plug 30 in the second position. The metallic plug 31 exposes outside the body 20 and the connector pins 40a of the second connector 40 are electrically connected to the connector pins 34a of the first connector 34, the elastic element of the second connector 40 is used in the insulating portion 32, so that the USB plug 30 can be tightly engaged between the top cover 21 and the bottom cover 22. Furthermore, referring to FIG. 10 and FIG. 11, when the USB plug 30 is in the second position, the first hook 212a of the top cover 21 is engaged with the fourth hook 32b of the insulating portion 32, the second hook 222a of the bottom cover 22 is engaged with the third hook 32a of the insulating portion 32, the metallic plug 31 faces outside the body 20.
When transmitting data, the protrusion 33 of the USB plug 30 is pushed to take off the USB plug 30, at the same time, the first hook 212a is separated from the third hook 32a and the second hook 222a is separated from the fourth hook 32b. Then, the USB plug 30 is revered to 180 degrees and is inserted between the first indentation 211 and the second indentation 212, so that the first hook 212a is engaged with the fourth hook 32b and the second hook 222a is engaged with the third hook 32a. At the same time, the connector pins 40a of the second connector 40 are electrically connected to the connector pins 34a of the insulating portion 32 and the metallic plug 31 is exposed outside the body 20, enabling direct connection and data communication with another portable electronic device.
When receiving the USB plug 30 in the body 20, the protrusion 33 is pushed and the USB plug 30 is accommodated so that the insulating portion 32 is separated from the body 20. The procedure is reversed when the USB plug 30 makes the metallic plug 31 faces the body 20. In addition, the metallic plug 31 is pushed along the bottom sliding portion 223 of the bottom cover 22 and the top sliding portion 224 of the top cover 22, and is limited between the first limiting portion 225 and the second limiting portion 226. At the same time, the first hook 212a of the top cover 21 is engaged with the third hook 32a of the insulating portion 32, and the second hook 222a of the bottom cover 22 is engaged with the fourth hook 32b of the insulating portion 32, to fix the USB plug 30 in the body 20.
The portable electronic device 10 with detachable USB plug can be easily received in the portable electronic device 10. When using the USB plug 30, the USB plug 30 can be reversed to connect to the portable electronic device 10 and another device for transmitting data without an additional data communication cable.
