Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an AC adapter used for portable electronic equipment such as a notebook personal computer, and more particularly to an AC adapter which is excellent in portability when stored in an electronic equipment and carried.

[0002]

2. Description of the Related Art Advances in semiconductor technology have led to miniaturization of electronic devices, and battery-powered portable electronic devices have become widespread. However, since the operating time (life) of the battery is at most about 10 hours, it is common to use an AC adapter instead of the battery as a power source when using the electronic device indoors. The AC adapter is usually installed outside the electronic device.
There is a problem in that an extra installation space is required for the C adapter. Therefore, as a solution to such a problem, as shown in FIG. 8, an AC adapter 32 is used instead of the battery 31 in the battery storage portion 33 in the electronic device body 30.
There has been proposed an AC adapter capable of detachably storing the AC adapter.

[0003]

However, even if the above-mentioned improved AC adapter is always used in the same place, there is no problem, but when it is used in another place, for example, it is usually used in the company. However, sometimes there is a problem that the AC cord of the hanging AC adapter gets in the way when trying to carry it at home. In order to prevent the cord from hanging down, it is necessary to bundle the cords with a cord or band, but the bundled cords still hang or project, which is an obstacle to carrying.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide an AC adapter which can improve the portability of an electronic device containing the AC adapter.

[0005]

In an AC adapter detachably housed in an electronic device body, an AC cord attached to the AC adapter is wound around the adapter when not in use, and in the state of the electronic device body. The structure that is stored in the
Furthermore, the front cover of the AC adapter is provided with a notch for pulling out the AC cord, and the rotary unit rotatably covers the connection between the AC cord and the AC adapter body. The root of the AC cord faces the notch, and the peripheral surface of the rotating part closes the notch when the AC cord is stored, or the plug of the AC cord closes the notch instead of the peripheral part of the connecting rotating part. Is characterized by.

[0006]

[Operation] The AC cord attached to the AC adapter
When not in use, the structure is such that it is wrapped around the adapter and stored in the body of the electronic device in that state. Therefore, when carrying the electronic device, there is no problem that the AC cord of the AC adapter hangs down and becomes an obstacle. In addition, since the inside of the AC cord wrapping part is hollow, it is possible to mount taller parts using the hollow part. Furthermore, since the notch for pulling out the AC cord is provided on the front cover of the AC adapter, it is impossible. Without the AC cord can be pulled out. Furthermore, a rotating portion that rotatably covers the connection portion of the AC cord and the AC adapter body is provided, and when used, the rotating portion rotates and the base of the AC cord faces the notch so that the cord can be pulled out. The structure is such that the peripheral surface of the rotating part closes the notch when storing, or the structure of the AC cord plug closes the notch instead of the peripheral surface of the connecting rotating part, so it is possible to prevent dust from entering from the notch. .

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of an AC adapter according to the present invention. In the figure, reference numeral 1 is an AC cord whose one end is supported by an AC adapter body, 2 is an AC cord winding portion projectingly provided on the upper surface of the adapter body, and 3 is a plug fixing claw facing the upper end portion of the adapter body. ,
Reference numeral 4 denotes a rotating portion that rotatably covers a portion where the AC cord 1 is connected to the AC adapter body, 5 denotes a front cover of the AC adapter, 6 denotes a notch provided at an upper edge portion of the front cover 5,
11 is a plug integrated at the tip of the AC cord 1, 12 is A
It is the root of C code 1. A concave portion 21 is formed on the peripheral surface of the AC cord winding portion 2 as shown in FIGS.
When not in use, the AC cord 1 is wound around the recess 21, and the AC adapter is stored in the battery storage 33 of the electronic device main body 30 (FIG. 8) in that state.

As shown in FIG. 1, since the rotating portion 4 is rotatable in both directions of the arrow and the AC cord is derived from a part of the side surface thereof, the AC cord 1 is attached to the peripheral surface of the AC cord winding portion 2. When wrapping around, the root of AC cord 1
With the position 12 as shown in the figure, it is wound around the recess 21 of the AC cord winding portion as shown in FIG. 2, and finally the plug 11 is fitted and fixed in the plug fixing pawl 3. The above A
A structure in which the inside of the C-cord winding portion 2 is hollow as shown in FIG. 3 is possible. This is realized by being integrated with the main body cover, for example, by molding. A
Since the printed circuit board 7 is mounted inside the C adapter and the tall component 8 and the like need to be mounted on the printed circuit board 7, the AC cord in which the tall component 8 is hollowed out as shown in the figure. It is mounted by utilizing the inside of the winding unit 2.

As shown in FIGS. 1, 2 and 4, a notch 6 is provided at the upper edge of the front cover 5. Rotate the rotating part 4 so that the root of the AC cord 1 is in use as shown in Fig. 4.
12 is opposed to notch 6, and AC cord 1 is pulled out from notch 6 to the outside. As a result, even though the upper edge of the front cover 5 is higher than the position of the base 12 of the AC cord, the notch 6 is formed in the state in which it is housed in the battery top 33.
With this, AC cord 1 can be pulled out without difficulty.

As shown in FIG. 5, when the AC cord is stored, the rotating portion 4 rotates and the peripheral surface of the rotating portion closes the notch 6.
This can prevent intrusion of dust and the like. FIG. 6 is a perspective view showing an embodiment in which the notch is covered by the plug 11. In this embodiment, the plug fixing pawl 3 is provided at a position facing the notch 6, the plug 11 is fitted and fixed between the front cover 5 and the plug fixing pawl 3, and the notch 6 is closed by the plug 11. Also, in this embodiment, AC
The root 12 of the cord is led out from the position (upper surface of the adapter body) shown in the figure, and the AC cord 1 is wound counterclockwise around the AC cord winding portion 2.

FIG. 7 shows another embodiment. Instead of the plug fixing pawl 3, a dummy plug insertion port (not shown in the figure) is provided on the upper surface of the AC adapter as a plug fixing means. It is also possible to provide the plug 11 and stand the plug 11 vertically to close the notch 6. In FIG. 1, the four corners of the concave peripheral surface of the AC cord winding portion 2 may be arcuate, or the two opposite sides (short sides) may be arcuate.

As described above, according to the present invention,
When the AC cord attached to the AC adapter is not used, it is wrapped around the adapter and stored in the main body of the electronic device in that state. Therefore, when carrying the electronic device, the AC cord of the AC adapter may hang down. There is no interruption. Also, since the inside of the AC cord wrapping part is hollow, it is possible to mount tall components by arranging it inside the hollow part, and a notch for pulling out the AC cord is provided on the front cover of the AC adapter. , The AC cord can be pulled out without difficulty.

Furthermore, a rotating portion is provided for rotatably covering the connecting portion between the AC cord and the AC adapter body, and when used, the rotating portion rotates so that the root of the AC cord faces the cut.
When the AC cord is stored, the peripheral surface of the rotating part closes the cut, or the plug of the AC cord closes the cut instead of the peripheral part of the connecting rotary part. When the AC cord is stored, it is possible to prevent dust and the like from entering through the notches.
