Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a retractable AC plug structure, and more particularly to a retractable AC plug structure in which a blade is protected when the blade is retracted.

[0002]

[Prior Art]

 FIG. 3 shows an example of a conventional accommodating AC plug.

The accommodating AC plug shown in this figure is used, for example, as a charger for a small rechargeable battery or an AC power adapter for a desktop computer, and the blade is shown by a chain double-dashed line in the figure during use. It is brought into a position by a fingertip and stands upright with respect to the outer surface of the case, and this blade portion is inserted into, for example, a wall surface AC outlet or the like.

FIG. 3 shows a state in which the blade is tilted when not in use and is housed in the storage portion. However, the blade is raised from this state to a use state (indicated by a two-dot chain line in the figure). To do this, proceed as follows.

First, a method of pinching the blades from the outside of both blades with fingers, for example, a thumb and an index finger (pinching from the X and Y directions in the figure), and second, the plug tip on one side. It is a method of pinching with your fingertip and pinching (pinching from the X, Z directions in the figure).

Therefore, in the vicinity of the tip of the blade of the blade accommodating portion, a portion of the case along the outer side of the blade is cut off so that the fingertip can be inserted, and the portion sandwiched by the blade is also a space. As a result, the blades are stored with almost half exposed.

[0007]

[Problems to be solved by the device]

 In the above-mentioned conventional example, since the blade is largely exposed during storage, when carrying it, it may be hit by another solid object to damage the blade, or conversely, it may be damaged by the tip of the blade. There was a problem of damaging other things.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a structure of a storage portion of a storage AC plug in which the blade is less exposed.

[0009]

[Means for Solving the Problems]

 The problem is that the blade storage section has a side wall that extends to the front end along the blade in the folded state and a height that approximately matches the width of the blade, and is sandwiched between the blades. The exposed portion of the blade is minimized by providing a protruding portion that is provided in a portion and a chamfered portion that is provided in the opening near the tip of the blade to manually raise the blade. Will be solved.

[0010]

[Action]

 As described above, the side wall that surrounds the blade extends to the tip of the blade, and the part that is sandwiched between the blades in the blade storage part has the same height as the width of the blade. Can be buried inside.

Further, the structure in which the opening in the vicinity of the blade tip of the blade housing has a chamfer makes it possible to hook the tip of the fingertip to the lower side of the blade even with a slight opening.

[0012]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIG.

FIG. 1 is a diagram showing a structure of a retractable AC plug used in a power supply device such as a desk-top computer when the retractable AC plug is accommodated.

In this figure, the blade housing portion 5 of the AC plug has a concave shape at a portion connected to the first surface 2 of the resin case 1 and the second surface 3 orthogonal to the first surface 2. It is formed in. When the AC plug blade 4 is used, it is raised by 90 degrees, and as shown by a chain double-dashed line in the figure, it is in a state of protruding perpendicularly to the first surface 2 of the case 1 and is inserted into an AC outlet. It is like this.

When the blade 4 is housed, the tip end of the blade 4 is in a positional relationship such that it is aligned with the second surface 3 of the case 1, and the side wall 5a surrounding the blade 4 of the blade housing portion 5 is It extends along the blade 4 to the tip of the blade 4.

FIG. 2A is a view of the opening of the blade accommodating portion 5 in FIG. 1 viewed from the X direction, and FIG. 2B is a sectional view taken along the line II-II of FIG. It is a figure. In both figures, the same parts as those in FIG.

As shown in more detail in FIGS. 2A and 2B, a projecting portion 6 is formed in a portion sandwiched by the blades 4, and an upper surface 6a of the projecting portion 6a is in the stored position. It is the same height as.

Further, a chamfered portion 5b is formed at a corner where the second surface 3 of the case 1 and the side wall 5a of the blade housing portion 5 intersect, and the second surface 3 and the lower surface 5e of the blade housing portion 5 are formed. A chamfer 5d is provided at the intersecting corner, and a chamfer 5c is provided at the corner where the second surface 3 and the upper surface 6a of the projecting portion 6 intersect. These chamfered portions 5b, 5c, 5d are large enough to hang the fingertips on the lower side of the blade 4, and the chamfered portions 5c and 5d have substantially the same plane.

As described above, except for the chamfered portion, the blade 4 is accommodated in the blade accommodating portion 5 formed in a concave shape on the first surface of the case 1 so as to be entirely buried therein. Since the exposed portion of 4 is small, the blade 4 does not hit the other object when the blade is housed and the blade 4 is not damaged, or the other object is not damaged by the blade 4.

Further, by having the protruding portion 6 sandwiched between the blades 4, when inserting and removing the AC plug into and from the AC outlet, the fingertip is inserted through the opening portion of the second surface of the blade housing portion 5 and energized. It also has the effect of preventing the risk of touching the blade 4.

Further, in comparison with the conventional example of FIG. 3, this embodiment has less recesses formed near the blade housing portion and the blade tip end portion, and accordingly has the advantage that the inner volume inside the case can be effectively used. have.

[0022]

[Effect of the device]

 As described above, according to the present invention, the blade of the stored AC plug can be buried in the blade storage portion, and the chamfered portion provided near the tip of the blade can be used to easily cause the blade with the fingertip. be able to.

Therefore, the exposed portion of the blade is minimized, the blade itself is protected from damage due to contact with other objects, and the tip of the plug also prevents damage to other objects. it can.
