DETAILED DESCRIPTION OF THE EMBODIMENTS
Wherever possible in the following description, like reference numerals will refer to like elements and parts unless otherwise illustrated.
Referring to FIG. 1 and FIG. 2, a portable adapter used for travel according to a first embodiment of the invention includes a first body 1, a power input 2, a power output 3, a second body 4, two connectors 5 and a pivoting unit 6. The first body 1 includes a first half part 11 and a second half part 12, which can be assembled together by engaging, screwing or ultrasonically welding. The first body 1 further has a first accommodating space 13 inside.
The first body 1 has a first opening 14 and a second opening 15 formed at opposite sides thereof. The power input 2 is received in the first opening 14 of the first body 1 in a manner which partially exposes the power input 2 through one side of the first body 1. The power input 2 is further fixed onto a first circuit board 7. The power input 2 can be a connector of any known format. In this embodiment, the power input 2 is a European standard male connector. The circuit board 7 is received in the first accommodating space 13 to electrically connect to the power input 2. The first circuit board 7 further has a protruding wave protection circuit (not shown) which provides a protecting function to prevent any sudden protruding waves from being generated.
The power output 3 is received in the second opening 15 of the first body 1 at the position next to the pivoting unit 6, in a manner which partially exposes the power output 3 through another side of the first body 1. The power output 3 can be a connector of any known format. In this embodiment, the power output 3 is a European standard female connector. The power output 3 is electrically connected to the first circuit board 7 via conductive wires 8. The power input 2 is connected to an external power line to input required power. The power output 3 is connected to a converter for external devices such as laptops so that power can be transmitted to the external devices.
The second body 4 includes a first half part 41 and a second half part 42, which can be assembled together by engaging, screwing or ultrasonically welding. The second body 4 further has a second accommodating space 43 inside for receiving a second circuit board 9.
The second body 4 has a third opening 44 for receiving the two connectors 5. The two connectors 5 are partially exposed through one side of the second body 4, and are further fixed onto and electrically connected to the second circuit board 9. The two connectors 5 can be connectors for telephone lines or internet cables. In this embodiment, the two connectors 5 are used to respectively input and output signals. The second circuit board 9 further has a protruding wave protection circuit (not shown) which provides a protecting function to prevent any sudden protruding waves from being generated. The second circuit board 9 can be further electrically connected to the first circuit board 7 via the conductive wires 8.
The pivoting unit 6 is mounted between the first body 1 and the second body 4. The configuration of the pivoting unit 6 is not particularly limited as long as the first body 1 and the second body 4 can be pivotally connected to each other. In this embodiment, the pivoting unit 6 includes two axial holes 61 and two rotating axils 62. The axial holes 61 are formed through the first body 1 near to the second opening 15. The two rotating axils 62 are placed through opposite sides of the second body 4, corresponding to the axial holes 61 so that the first body 1 and the second body 4 can be pivotally connected to each other by the pivoting unit 6. Thereby, the portable adapter used for travel according to the invention is achieved.
In addition to the protruding wave protection, the portable adapter used for travel according to the invention also provides surge protection for the telephone line or internet cable connections, granting the user more convenience and safety when using their electronic devices.
Furthermore, the portable adapter used for travel according to the invention is foldable. Therefore, the pivoting unit 6 unfolds the first body 1 and the second body 4 at an angle of 180 degrees relative to each other, as shown in FIG. 3 to reduce the volume of the portable adapter when the portable adapter is packed for traveling or transportation. When the portable adapter according to the inventing is used in combination with a converter for a laptop, the pivoting unit 6 allows the first body 1 and the second body 4 to unfold to an angle of 90 degrees relative to each other, as shown in FIG. 2, for the connectors 5 for a telephone line or an Internet cable to plug in or out from the laptop.
Unfolding the first body 1 and the second body 4 at the angle of 180 degrees allows the power output 3 to be completely hidden inside a space formed between the first body 1 and the second body 4, so that the power output 3 can be protected from being deformed by impacts. When used in combination with the laptop, the connectors 5 can be exposed only by unfolding the first body 1 and the second body 4 to the angle of 90 degrees whereas the portable adapter 3 is partially hidden between the first body 1 and the second body 4, which requires less space for holding this portable adapter.
It should be apparent to those skilled in the art that the above description is only illustrative of specific embodiments and examples of the present invention. The present invention should therefore cover various modifications and variations made to the herein-described structure and operations of the present invention, provided they fall within the scope of the present invention as defined in the following appended claims.
