Compact traveling-use power adapter structure

[0001] a) Field of the Invention

[0002] The present invention relates to a compact traveling-use power adapter structure, and more particularly to a compact traveling-use power adapter, with a small volume and rotational design, that can be widely applied in a variety of power plugs in many countries, for all kinds of electronic products.

[0003] b) Description of the Prior Art

[0004] In reflecting to a variety of power voltages and currents in countries all of the world, typical house-used electronic products have different power plugs and sockets to be in compliance with their own power voltages and currents. However, there are quite a few of power sockets with similar power voltages and currents. Therefore, in order to be able to use the house-used electronic products in different countries during traveling, a power adapter appears in a market. Referring to FIG. 1, it shows a power adapter a comprising a power plug a2 and a power socket a3 on a casing a1, using a one-to-one, one-to-two, and one-to-many styles. While in use, a power plug b1 of an electronic product b is inserted into the power socket a3 on the power adapter a, and the power plug a2 on the power adapter a is adjusted to be in compliance with the power socket a3 used in a country, such that the power plug b1 can be inserted. A connecting device a6 is installed between a socket port a4 and a plug port a5, which is used by the power adapter a to assemble different socket ports a4 and plug ports a5, without changing the power plug of an electronic product. However, due to large volume of a power adapter, it is inconvenient to carry or difficult to adjust the power adapter.

[0005] After decreasing the volume of an entire power adapter, the inventor uses a different design than the conventional assembling method, to install all the adjusting structures in the power adapter at the same time. While in use, via directly rotating a plug port out of a casing of power adapter, a power plug of an electronic product can be inserted into a socket port of the power adapter. Due to the advantages of compact volume, and easiness of operation, the practicability and convenience can be actually improved.

[0006] The primary object of the present invention is to provide a small and easy to carry compact traveling-use power adapter structure, having a variety of adapting styles for adjusting, and with practicability and convenience.

[0007] Accordingly, the present invention comprises primarily a casing and several adjustable adapting plugs. The casing is divided into an upper casing and a lower casing, wherein several slots of different styles are located on the upper casing. Several conducting clips are installed in the slots to clip in contact terminators of inserted electronic products, and connected with curve-shaped conductible metal plates between the upper and lower casing. Two adjustable adapting plugs are installed on two sides at the bottom of lower casing, respectively, with an L-shaped common grounding terminator in the center of the adjustable adapting plugs. Pivoting cylinders protrude from two corner sides of the common grounding terminator, such that the adjustable adapting plugs installed at two sides of the grounding terminator can be stored via inward rotating. One adjustable adapting plug consists of a flat and rotatable contact terminator installed on a rotating seat, and connected with the curve-shaped conductible metal plates between the upper and lower casing, using a conducting junction protruded from the rotating seat after installation. The other adjustable adapting plug consists of two cylindrical contact terminators installed on a clip-able rotating seat, and connected with the curve-shaped conductible metal plates between the upper and lower casing, using a conducting junction protruded from the rotating seat.

[0008] Accordingly, in using the aforementioned structure, a power plug of an electronic product is directly inserted into the slots at the top of the power adapter, and the position of adjustable adapting plugs is adjusted to be in compliance with the type of power socket used in a country. Thus, the room needed for storing two adjustable adapting plugs can be minimized, and a storage method which rotates the adjustable plugs towards the central common grounding terminator is taken, in order to assemble the socket port and the plug port into the same casing, thereby minimizing the entire volume used by the power adapter, and facilitating the easiness of carry. On the other hand, using a rotating method to take out the necessary adjustable adapting plugs, and choosing to retrieve or not to retrieve the central common grounding terminator with the same method as the adjustable adapting plugs, is very simple to operate. In addition, the flat contact terminators and the cylindrical contact terminators also contain adjusting structures, and thus can be used for a variety of power sockets. Accordingly, the present invention is very practical and easy to use.

[0009] To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

[0023] Referring to FIG. 2, FIG. 3, FIG. 4A, FIG. 4B, and FIG. 4C, the present invention comprises primarily a casing 10, and several adjustable adapting plugs 20, wherein the box-shaped casing 10 is assembled with a top casing 11 and a lower casing 12. Several slots of different types 11a are located at the top of upper casing 11, with corresponding conducting clips 11b inside the slots 11a, which will be aligned with clip parts 11b1 of the conducting clips 11b. The conducting clips are connected with curve-shaped conductible metal plates 15 between the upper casing 11 and lower casing 12, and the conducting clips 11b can clip in a power plug 2 of an electronic product inserted into the slots 11a. Two adjustable adapting plugs 20 are installed on two sides at the bottom of lower casing 12, respectively, with a common grounding terminator 12a installed in the center of the adjustable adapting plugs 20. A pivoting cylinder 12b protrudes from the corner of the L-shaped grounding terminator 12a, such that the adjustable adapting plugs 20 can be stored or opened for use, via inward rotating toward the grounding terminator 12a center, wrapped by a grounding cladding 12c. One adjustable adapting plug consists of two flat and rotatable contact terminators 21 installed on a rotating seat 22, with cylinders 22a protruding from two sides of the rotating seat 22. Positioning points 22a1 are located on the cylinders 22a, which are installed in corresponding positioning holes 12d of the lower casing 12. After installing the flat contact terminators 21 on the rotating seat 22, contact points 21a protruding from the bottom are connected with the curve-shaped conducting metal plates 15 between the upper casing 11 and lower casing 12. The other adjustable adapting plug 20 consists of two cylindrical contact terminators 23 installed on a clip-able rotating seat 24 The rotating seat 24 sits on two independent rotating seats 24a, connected by a spring 24b. Two positioning columns 24c protruded from the other ends of the independent rotating seats 24a without the spring 24b are installed at the corresponding positioning holes 12d of the lower casing 12, and pushed out of the lower casing 12. After installing the cylindrical contact terminators 23 on the independent rotating seats 24a, conducting junctions 23a at the bottom of the independent rotating seats 24a are connected with the curve-shaped conductible metal plates 15 between the upper casing 11 and the lower casing 12.

[0024] Referring to FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, and FIG. 5E, which shows several schematic views of the implementation for the present invention, the power plug 2 of an electronic product is directly inserted into the slots 11a of the aforementioned power adapter 1, and the position of adjustable adapting plugs 20 of the lower casing 12 is adjusted to be in compliance with the usage of power socket 3 in a country.

[0025] Referring to FIG. 6 and FIG. 7, which shows two schematic views of a second implementation of the present invention, a lower casing 12 remains the same as the aforementioned first structure, with pivoting plates 12e protruded downward from two edges of one side of the lower casing 12. Circular slots 12e1 in the center of pivoting plates 12e can be used to install a rotating casing 13, and a conductible metal plate 14 is located between two pivoting plates 12e and the rotating casing 13. Two conducting parts 14a are located at the top of a conductible metal plate 14, and a rotating part 14b is protruded downward from one side of the conductible metal plate 14, with a circular hole 14b1 in the center of the rotating part 14b. Two conducting parts 14a can be connected with conducting junctions 21a and 23a at the back of a flat contact terminator 21 and a cylindrical contact terminator 23, respectively. The rotating casing 13 consists of a bottom casing 13a and a back casing 13b, with several different types of slots 13b1 on the back casing 13b. Corresponding conducting clips 11b are installed inside the slots 13b1, with clip parts 11b1 of the conducting clips 11b aligned with the slots 13b1 on the back casing 13b. A pivoting column 11b2 protruding from one side of the conducting clip 11b can go through the circular hole 14b1 of the rotating part 14b of the conductible metal plate 14, and convex parts 13a1, which are located at two sides at the bottom casing 13a, can be emplaced into the circular slots 12e1 in the center of pivoting plates 12e, correspondingly. Accordingly, the volume of the entire aforementioned power adapter can be reduced further, and the method of application still remains the same as the first implementation, thereby achieving the same object of the first structure of the present invention.
