In the embodiment, the connectors can be arranged at the surrounding side of the circuit board 120, for example, the first connector 122 and the second connector 124 are respectively disposed at the two sides of the first circuit board 120, which are perpendicular each other, and the third connector 126 and the fourth connector 128 are disposed at the same side of the first circuit board 120. The connection plugs of the several connectors are disposed in such a way that they toward the second opening 114 and thereby are electrically connected to other electronic devices, and the connection plugs may be a removable media connection port, a parallel port, a serial port, a connection port for a local area network, a D-sub video output port, or S terminal output port, etc.
Continuing to refer to FIG. 1 and FIG. 2, the rotating element 130 has a first portion 132 and a second portion 134, wherein the first portion 132 is pivoted to the housing 110, and a part of the first portion 132 passes through the first opening 112 to be exposed outside the housing 110. The second portion 134 is fixed to the first circuit board 120 and further includes a first joint 132a fixed onto the first circuit board 120, so that the rotating element 130 can be securely fixed onto the first circuit board 120.
Moreover, the portable computer 100 further includes an internal frame 150, disposed on the first circuit board 120 and surrounding the multiple connectors disposed onto the first circuit board 120. The internal frame 150 has a plurality of windows, such as, a first window 152 corresponding to the connection plug 122a of the first connector 122, a second window 154 corresponding to the connection plug 124a of the second connector 124, a third window 156 corresponding to the connection plug 126a of the third connector 126 and a fourth window 158 corresponding to the connection plug 128a of the fourth connector 128, and so on. In the embodiment, the internal frame 150 may be made of conductive material such as metal, etc, and electrically connected to the grounded terminal of the first circuit board 120.
In addition, referring to FIG. 1 and FIG. 3A, the portable computer 100 further includes a locking element 140 that is slidably disposed or pivoted to the housing 110. The locking element 140 may shift between an unlocked position and a locked position by force, wherein when the locking element 140 is disposed at the locked position, the locking element may lock the rotating element 130 to preventing it from rotating.
To simplify the description, the following takes the first connector 122 and the second connector 124 as an example to describe the embodiment of the present invention, however, the first connector 122 and the second connector 124 can be substituted by other connectors such as a third connector 126, a fourth connector 128, etc. Referring to FIG. 2, when the users want to connect the second device 200, such as a display device, USB mass storage disc or printer, to the portable computer 100 of the embodiment of the present invention, the users can check, through the second opening 114, whether the second connection plug 124a (as shown in FIG. 1) of the second connector 124 disposed in the second opening 114 is suitable for being connected to the second device 200. If the second connection plug 124a is not suitable for being connected to the second device 200, the users can apply force to the locking element 140 to make it leave the locked position and move to the unlocked position, thereby releasing the limitation of the rotating element 130 by the locking element 140 and permitting the rotation of the rotating element 130.
FIG. 3A is a bottom view of the housing shown in FIG. 2, and FIGS. 3B-3C are the schematic diagrams of the locking element in the unlocked position and the locked position, respectively. Taking the lock element 140's being slidably disposed on the housing 110 as an example, when the locking element 140 is located at the locked position, as shown in FIG. 3A, the locking element 140 may lock the rotating element 130 so that the rotating element 130 can not rotate. When the users want to change the exposed connection plug of the connector in the second opening 114, the users may apply force to push the locking element 140 to move it to the unlocked position from the locked position, then, the users again apply force to the rotating element 130 to rotate the rotating element 130, as shown in FIG. 3B.
In particular, when the locking element 140 leaves the locked position, the users may apply force to the rotating element 130, so that the rotating element 130 may bring the first circuit board 120 to rotate with the rotating element 130 relative to the housing 110. Therefore, the second connector 124 disposed onto the first circuit board 120 may leave the second opening 114 due to the rotation of the first circuit board 120, so that the second opening 114 may expose another connection plug, for example, the first connection plug 122a. Thereafter, the user may again check whether the first connection plug 122a is suitable for being connected to the second device 200 (not shown).
When the users make sure their desired first connection plug 122a of the first connector 122 is exposed in the second opening 114, the users can push the lock element 140 back to the locked position to lock the rotation element 130, as shown in FIG. 3C.
Similarly, if the first connection plug 122a is not suitable for being connected to the second device 200, the users may repeat the above steps to select the connection plug of the suitable connector. It can be obviously seen from the above that the portable computer 100 of the embodiment of the present invention can provide more kinds of connectors for customer selection in the limited width than the conventional portable computer. In addition, to help user to select the connection plug more conveniently, a text description can be subscribed in the corresponding position of the bottom 110a (as shown in FIG. 1 or FIG. 3A) of the housing 110, or, drawing a symbol for representing the connection port is also applicable.
FIG. 4 is a schematic diagram showing other portable computer is electrically connected to the second device through the first circuit board and the second circuit board. Referring to FIG. 4, the portable computer 100 further includes a second circuit board 160, disposed in the housing 110 and electrically connected to the first circuit board 120 through a transmission cable 170. In the embodiment, the second circuit board 160 is a main board of the notebook computer, and the second circuit board 160 can also be electrically connected to the first circuit board 120 through the flexible bus. After the second device 200 is electrically connected to the first circuit board 120 of the portable computer 100, the data can be transmitted between the second circuit board 160 and the second device 200 through the first circuit board 120. Of course, a plurality of circuit boards can also be disposed in the portable computer 100 of the embodiment of the present invention, and a plurality of connectors are disposed onto all of the circuit boards, therefore the users can electrically connect a plurality of different second devices 200 to the portable computer 100 of the embodiment of the present invention.
In summary, the portable computer of the embodiment of the present invention can accommodate more and more kinds of connectors in its limited width than conventional technologies. The connectors are arranged at the side of the circuit board, and the users can rotate the rotating element to select the desired connector, so that the portable computer of the embodiment of the present invention can provide more and more kinds of connectors to meet the users' desirability.
