Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cord housing attachment of an AC adapter, and more particularly to a cord housing attachment of an AC adapter that converts alternating current into direct current and supplies direct current power to various electronic devices.
[0002]
[Prior art]
There is an AC adapter that changes a commercial AC power source to a DC power source in order to supply DC power to an electronic device. There are various types of such AC adapters. For example, an AC plug for insertion into an AC outlet is pivotally supported by the main body case so that it can be accommodated and protruded from the case. There is something configured.
[0003]
In these AC adapters, a cord for supplying DC power from the main body case to the electronic device is provided, and a connector that fits into the receptacle of the electronic device is attached to the tip portion. Therefore, when this AC adapter is not used, or when carrying it, it is necessary to take measures such as rounding or tying the cord. Processing becomes complicated. Further, the cord itself is subjected to abnormal stress due to rounding or tying, and there is a possibility of disconnection.
[0004]
Here, with reference to Patent Document 1, an AC adapter case is disclosed in which a groove for winding a cord is provided on the outer periphery of a storage portion for storing the AC adapter. When storing or carrying the AC adapter, the AC adapter is fitted into the case housing and the cord is wound around the groove to facilitate cord processing and eliminate abnormal stress on the cord. It has become.

[Problems to be solved by the invention]
The AC adapter case disclosed in Patent Document 1 described above has a structure in which the AC adapter is simply fitted into the housing portion of the case, and there is no mechanism for fixing both. Therefore, it is conceivable that the AC adapter is displaced or detached from the case. In such a case, since the cord of the AC adapter is wound around the cord winding portion of the case, abnormal stress may be applied to the cord, and there is a possibility of disconnection.
[0007]
An object of the present invention is to provide an AC adapter cord accommodation attachment in which an AC adapter is fixed and an abnormal stress is not applied to the cord when the AC adapter cord is accommodated.
[0008]

In the state where the AC plug is inserted into the insertion hole at a position where the AC plug is accommodated in the main body, The AC adapter has a structure that can be placed on the box-shaped main body.
[0009]
Another AC adapter cord housing attachment according to the present invention is an AC adapter cord housing attachment having an AC plug that is pivotally supported with respect to a box-shaped body and can be housed in the body. A convex portion having a side wall portion that forms the bottom surface of a groove for winding, a pair of flanges provided above and below the side wall portion, and an insertion hole that is attached to one of the pair of flanges and into which the AC plug is inserted. One of the pair of flanges on the upper surface of the box-shaped main body of the AC adapter in a state where the AC plug is inserted into the insertion hole at a position where the AC plug is housed in the main body. It has the structure which can be mounted.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 1 (a) is a perspective view showing the relationship between an attachment 1 and an AC adapter 2 according to an embodiment of the present invention, and FIG. 1 (b) is an attachment. 1 is a side view of FIG. 2 shows a perspective view (a), a side view (b), and a front view (c) of the attachment 1, respectively, and FIG. 3 is an external perspective view showing the attachment state of the attachment 1 and the AC adapter 2. It is. 1 to 3, equivalent parts are denoted by the same reference numerals.
[0011]
Referring to FIGS. 1 to 3, the attachment 1 includes a side wall 10 that is a bottom surface of the groove 13 for winding the cord 22 of the AC adapter 2, and upper and lower sides attached to the upper and lower sides of the side wall 10. It has a pair of flanges 11 and 12 and a convex portion 14 that protrudes and is attached to the lower flange 12. The protrusion 14 is provided with a plug insertion hole 15 for inserting the AC plug 21 of the AC adapter 2. Further, the upper flange 11 is provided with a connector accommodating portion 16 for accommodating a connector 23 provided at the distal end portion of the cord 22 connected to the AC plug 2. Is provided with a cord fitting portion 17 for fitting the cord.
[0012]
The AC adapter 2 has a box-type main body 20, and an AC plug 21 is pivotally supported with respect to the main body 20 so as to be housed in the main body. A cord 22 is connected to the main body 20, and a connector 23 is attached to the tip portion thereof. By fitting this connector 23 into a receptacle of an electronic device (not shown), a desired DC power is supplied from the AC adapter 2 to the electronic device. When supplying such power, the AC plug 21 of the AC adapter 2 is rotated so as to protrude from the main body 20, and the protruded AC plug 21 is inserted into a commercial AC outlet (not shown). Then, AC / DC conversion is performed, and power supply to the electronic device becomes possible.
[0013]
When the power supply to the electronic device is finished, the AC plug 21 is left protruding from the main body 20 of the AC adapter, and the protruding AC plug 21 is inserted into the plug insertion hole 15 provided in the convex portion 14 of the attachment 1. And the AC plug 21 is rotated with respect to the main body 20 and stored in the main body 20, whereby the attachment 1 is placed on the AC adapter 2 as shown in FIG. It will be fixed to 2. The cord 22 can be accommodated by winding the cord 22 along the groove 13 of the attachment 1.
[0014]
At this time, the connector 23 is accommodated in the connector accommodating portion 16 provided on the upper flange 11 of the attachment 1 and the cord near the connector 23 is fitted into the cord fitting portion 17 so that the connector 23 and the cord 22 are also stabilized. Fixed.
[0015]
The size of the upper and lower flanges 11 and 12 of the attachment 1 is substantially the same as the size of the attachment placement surface of the box-shaped main body 20 of the AC adapter 2 so that the attachment 1 and the AC adapter 2 are shown in FIG. Thus, it becomes a single quadrangular prism shape, so that unnecessary portions such as protrusions do not occur, and it is easy to carry and store together neatly.
[0016]
4 and 5 are views showing another embodiment of the present invention. FIG. 4 is a perspective view showing the relationship between the attachment 1 and the AC adapter 2 according to this embodiment, and FIG. FIG. 5B is a perspective view showing a state in which the cord is accommodated in the state shown in FIG. 5A. 4 and 5, the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals.
[0017]
In the previous embodiment, the AC adapter 2 and the attachment 1 are mounted in a stacked manner, but this is not a good solution in terms of volume. Therefore, in this embodiment, as shown in FIG. 5, the AC adapter 2 is fitted into the attachment 1 so that both are attached.
[0018]
That is, the upper and lower flanges 11 and 12 are provided with an AC adapter insertion portion 18 into which the box-shaped main body 20 of the AC adapter 2 can be completely inserted, and the upper flange 11 is provided with a connector storage pocket 32 for storing the connector 23.
[0019]
When the AC adapter 2 is not used, the AC adapter 2 is covered with the attachment 1, the cord 22 of the AC adapter 2 is wound around the groove 13 formed on the outer periphery of the attachment 3, and the connector 23 is stored in the storage pocket 32. As a result, the unnecessary cord 22 and connector 23 can be stored.
[0020]
Further, by constituting the attachment 1 using an elastic material such as a soft mold, it is possible to provide a buffering function (cushion function) against an improper impact force caused by dropping or the like.
[0021]
【The invention's effect】
As described above, according to the present invention, since the attachment is fixed by utilizing the storage state of the AC plug when the AC adapter is not used, unnecessary force (stress) is applied to the AC cord of the AC adapter. Is prevented and disconnection and the like can be prevented.
