The present invention relates to a foldable USB connection port. In particular, this invention relates to a foldable USB connection port that is installed to a USB hub or a laptop and the angle of the USB port is adjustable.
As shown in FIG. 1, the USB hub 1 a of the prior art is disclosed. A plurality of USB ports 12 a are installed on an appropriate location of a housing 11 a, and there is a USB control circuit (not shown in the figure) in the housing 11 a. The USB ports 12 a are respectively and electrically connected with the control circuit. The USB port 12 a can be movably plugged with a peripheral 2 a, such as an MP3 portable disk or a USB optical mouse, etc. Then, the USB hub 1 a is linked with a laptop 4 a via one of the USB ports 12 a and a USB transmission line 3 a. In this way, the peripheral 2 a of the laptop 4 a is expanded.
However, the USB hub 1 a and the laptop 4 a only can be movably plugged with the peripheral 2 a and the USB transmission line 3 a, etc. When a large sized peripheral 2 a is plugged with one of the USB ports 12 a, the adjacent USB port 12 a cannot be plugged with another peripheral 2 a due to the large sized peripheral 2 a. Therefore, the number of the expanded peripherals 2 a is restricted. Furthermore, the function of expanding the peripheral 2 a of the USB ports 12 a is limited due to the dimensions of the peripheral 2 a. SUMMARY OF THE INVENTION
One particular aspect of the present invention is to provide a foldable USB connection port. The user can movably adjust the angle of the USB port. When one USB port is plugged with a peripheral and an adjacent USB port is plugged with another peripheral, these two USB ports are adjustable so they can be located in different directions. Therefore, the problem of it not being possible for two adjacent USB ports to be plugged with the peripherals simultaneously due to the dimensions of the peripheral can be avoided.
The foldable USB connection port includes a body having a plurality of first connection parts, and a plurality of USB ports that respectively has a second connection part. The second connection parts of the USB ports are respectively and movably installed on the first connection parts of the body.

Reference is made to FIG. 2 and FIG. 8. The foldable USB connection port includes a body and a plurality of USB ports 3. The body can be a USB hub 1 or a laptop 2.
FIGS. 2 to 7 show a first embodiment of the body of the present invention. The body is a USB hub 1. The USB hub 1 is composed of an upper shell body 11 and a lower shell body 12, and has a square-box shape. There is a USB control circuit 13 received in the USB hub 1 and fastened on the lower shell body 12. The USB hub 1 includes a plurality of first connection parts 14. A concave slot 15 is formed at an appropriate location on the USB hub 1, and the concave slot 15 is formed from the upper shell body 11 to the lower shell body 12. The first connection parts 14 are respectively located on the wall of the concave slots 15. Alternatively, a plurality of opening slots 16 are formed at an appropriate location on the USB hub 1, and the opening slot 16 is formed from the upper shell body 11 to the lower shell body 12. The opening slot 16 is hollow (as shown in FIG. 6 and FIG. 7). The first connection parts 14 are respectively located on the wall of the opening slots 16. Moreover, on the wall of the opening slots 16, there can be two sets of the first connection parts 14. The first connection parts 14 are columns, circular holes, thorn gears, or thorn gear holes. The first connection parts 14 are composed of a pair of columns, circular holes, thorn gears, or thorn gear holes that are respectively and oppositely located on the wall of the concave slot 15 or the opening slot 16 of the USB hub 1.
The USB ports 3 are wrapped with an insulating shell body 31, such as a plastic material. The USB port can be a USB2.0 or a Mini USB. The USB ports 3 respectively have a second connection part 32. The second connection part 32 of the USB ports 3 can be columns, circular holes, thorn gears, or thorn gear holes (as shown in FIGS. 3, 4 and 5). The second connection part 32 is composed of a pair of columns, circular holes, thorn gears, or thorn gear holes that are respectively located on the opposite right side and the left side of the USB ports 3. On the rear of the USB ports 3, there is a transmission device 33, such as a bus, a conducting line, or a pin. The transmission devices 33 of the USB ports 3 are respectively and electrically connected to the USB control circuit 13 of the USB hub 1.
The second connection part 32 of the USB ports 3 are respectively and movably installed on the first connection parts 14 of the USB hub 1. If the second connection part 32 is a circular hole, then the first connection part 14 is a column. If the second connection part 32 is a thorn gear, then the first connection part 14 is a thorn gear hole. The first connection part 14 is wedged into the second connection part 32 so that the USB port 3 can be moved upward and downward on the USB hub 1 to adjust its location angle (as shown in FIG. 2). For another embodiment, a pair of USB ports 3 (as shown in FIG. 7) are located on the upper side and lower side of the USB hub 1 according to the user's requirement. Therefore, the number of the USB ports is increased.
Furthermore, there is an upload USB port 4 on the USB hub 1. The upload USB port 4 is located at an appropriate location of the lower shell body 12 of the USB hub 1, and electrically connected with the USB control circuit 13 so that the USB ports 3 are linked with the upload USB port 4. Alternatively, the upload USB port 4 is movably installed on the USB hub 1. As described above, the upload USB port 4 is movably installed on the USB hub 1 that is same as the USB ports 3.
FIGS. 8 to 11 show a second embodiment of the body of the present invention. The body is a laptop 2. There are a plurality of first connection parts 22 on the shell body 21 of the keyboard of the laptop 2. A plurality of concave slots 23 are formed at appropriate locations of the shell body 21 of the on the concave slots 23. Alternatively, a plurality of opening slots 24 are formed at an appropriate location of the shell body 21. The first connection parts 22 are respectively located on the opening slots 24. The first connection parts 14 are composed of a pair of columns, circular holes, thorn gears, or thorn gear holes that are respectively and oppositely located on the wall of the concave slot 24 or the opening slot 24. The second connection part 32 of the USB ports 3 is respectively and movably located on the first connection part 22 of the shell body 21 of the laptop 2 so as to provide the same function described in the above sections. The transmission device 33 of the USB ports 3 is respectively and electrically connected to the motherboard in the laptop 2. Thereby, the USB ports 3 are linked with the laptop 2.
As shown in FIG. 12, the body 12 (such as the USB hub 1) further includes a plurality of bases 17. The base 17 has a U-shape. The first connection parts 14 are respectively located on the wall of the bases 17. The second connection part 32 of the USB ports 3 are respectively installed on the first connection part 12 of the bases 17. The bases 17 can be fastened on the body, or can be movably installed on the body.
The present invention movably installs the USB ports 3 on the body 1 (such as the USB hub 1, or the laptop 2) so that the user can movably adjust the angle of the USB ports 3. When one USB port 3 is plugged with a peripheral 5 (as shown in FIG. 7) and an adjacent USB port 3 is plugged with another peripheral 5, these two adjacent USB ports 3 are adjustable and can therefore be located in different directions. Therefore, the problem that two adjacent USB ports 3 cannot be plugged with the peripherals simultaneously due to the dimensions of the peripheral can be avoided.
