I have. Here, the moderation concave grooves 42A, 42B are formed in the small-diameter portions 4B, 4C of the rotary shaft 4 at regular intervals of 90 degrees so that the plug 3 can be turned over by 90 degrees together with the rotary shaft 4. I have.
[0038]
Next, the operation of the plug device according to the present embodiment will be described.
(I) First, in a usable state in which the plug 3 is inverted, as shown in FIGS. 1 to 3, the plug-side electrode mounting body 6 is located between the two housing-side electrode mounting bodies 8A and 8B opposed to each other. (See FIGS. 2 and 6). The plug 3 is positioned so as to have a predetermined rotation angle about the shaft portion 5, and as shown in FIG. 6A, a moderation provided on the housing-side electrode mounting bodies 8A and 8B. The convex ridges 81A and 81B are brought to a position facing the concave groove 61 for moderation formed in the plug-side electrode mounting body 6.
Therefore, in this state, the plug 3 is no longer rotatable.
[0039]
By the way, although not limited to this state, as described above, the housing-side electrode mounting bodies 8A and 8B are always subjected to the elastic biasing force toward the plug-side electrode mounting body 6 by the coil springs 73A and 73B. Has been granted. Therefore, in this state, the housing-side electrodes 82A and 82B are relatively strongly pressed against the plug-side electrode 62, and both are electrically connected in a good state.
[0040]
Therefore, when the plug main body 3 is inserted into an outlet provided on a wall of a house or the like, this outlet is connected to the plug-side electrode 62 via the plug main body 3 and further to the housing 1 via the housing-side electrodes 82A and 82B. It is electrically connected to an internal electric circuit or a conductor drawn out of the housing 1.
That is, here, the housing-side electrodes 82A, 82B are not shown, but are connected to an electric circuit inside the housing 1 using a coil spring 73A, 73B or another conductive wire, or a conductive wire drawn out. It is electrically connected.
[0041]
(II) Now, in this state, if the operation button 92 shown in FIG. 1 is pressed in the direction indicated by the arrow A (see FIG. 4), the taper portion 91 formed on the operation lever 9 is moved by the sliding levers 83A and 83B. The sliding levers 83A, 83B move in the direction B away from each other in order to abut against and press the tapered portions 84A, 84B. Therefore, the housing-side electrode mounting bodies 8A, 8B also have elasticity of the coil springs 73A, 73B. The direction shifts in the direction B (see FIG. 4) apart from the plug-side electrode mounting body 6 against the urging force.
That is, in this state, as shown in FIG. 6 (B), the moderating ridges 81A and 81B formed on the housing-side electrode mounting bodies 8A and 8B extend from the moderating concave grooves 61 formed on the plug-side electrode mounting body 6. As a result, the plug 2 can be freely rotated in the horizontal (X) direction (see FIG. 7) about the shaft 5.
[0042]
(III) Therefore, as shown in FIG. 7, in this state, the plug 2 is rotated 90 degrees in the horizontal (X) direction, and when the hand is released from the operation button 92, the plug 2 is moved from the state of FIG. In the state rotated by 90 degrees, the moderating ridges 81A and 81B provided on the housing-side electrode mounting bodies 8A and 8B are provided on the plug-side electrode mounting body 6 as in the state shown in FIGS. The detent groove 61 can be fitted. As a result, the plug-side electrode 62 provided on the plug-side electrode mounting body 6 can be electrically connected to the housing-side electrodes 82A and 82B provided on the housing-side electrode mounting bodies 8A and 8B, respectively.
[0043]
As described above, according to the present embodiment, even when the plug 2 is rotated by 90 degrees about the shaft portion 5 with the plug 2 inverted, the posture of the plug 2 can be changed to a usable state. Can be. Therefore, even if it is difficult to insert the plug into the outlet at a certain rotation angle due to the mounting position of the outlet, etc., there is a possibility that the plug can be easily inserted into the outlet by changing the rotation angle of the plug 2. It has the advantage of being convenient.
[0044]
(IV) Further, according to the present embodiment, as shown in FIG. 8, the plug 2 can be turned over by rotating the plug 2 in the Y direction about the rotation shaft 4, and the plug 2 can be stored in the plug housing. Can be completely housed in the concave portion 14.
That is, in the present embodiment, when the operation button 92 is pressed in the direction of arrow A (see FIG. 4), as described above, the direction B in which the housing-side electrode attachment bodies 8A and 8B are separated from each other (see FIG. 4). ), And the moderation convex ridges 81A and 81B provided on the housing-side electrode mounting bodies 8A and 8B come out of the moderation concave grooves 61 provided on the plug-side electrode mounting body 6 as shown in FIG. State. Therefore, in this state, the plug 2 can be arbitrarily rotated in the vertical (Y) direction (see FIG. 8) together with the rotation shaft 4 (the large diameter portion 4A).
[0045]
(V) Therefore, if the plug 2 is rotated 90 degrees in the vertical (Y) direction together with the rotary shaft 4 in this state, the plug 2 including the blades 3A and 3B can be used as shown in FIG. The plug device can be completely housed, and can be an excellent plug device that is easy to carry without a protruding portion from the housing 1.
[0046]
As described above, according to the present embodiment, the concave grooves 42A and 42B for the moderation in the small diameter portions 4A and 4B of the rotary shaft 4, and the convex portions 76A and 76B for the moderation in the bearings 74A and 74B that support the rotary shaft 4 in the axial direction. Are provided, respectively. Therefore, the concave grooves 42A and 42B and the convex portions 76A and 76B can provide the rotation of the rotating shaft 4, that is, an appropriate moderation at the two positions of the plug 2 in the horizontal and inverted positions, respectively. The plug 2 can be fixed stably in either the horizontal or inverted state.
[0047]
In the present embodiment, the ridges 7A, 7B for bearings are formed in the housing 1, and the ridges 7A, 7B for bearings are provided with holes 72A, 72B for storing coil springs and concave grooves 71A, 71B for holding the sliding lever. Although they are formed, they may be provided on separate members. Further, in the present embodiment, the rotating shaft 4 is provided in the plug accommodating recess 14, but only the plug body 3 is accommodated in the plug accommodating recess 14, and the rotating shaft 4 is not the plug accommodating recess 14. It may be configured to be provided inside the housing 1. With this configuration, the external appearance of the entire plug device can be further improved.
[0048]
In the present embodiment, a recess for an operation button may be provided outside the housing 1 and the operation button 92 may be housed in the recess for the operation button. With such a configuration, careless rotation of the plug main body 3 due to accidentally pressing the operation button 92 can be prevented. Further, the appearance of the entire plug device can be further improved. In particular, if the operation button 92 is housed by providing a recess for the operation button on the surface of the housing 1 where the plug body 3 is inverted, careless rotation of the plug body 3 while the plug body 3 is inserted into the outlet can be prevented. , Can be more effectively prevented.
[0049]
Note that, in the present embodiment, the constituent members of each unit have a configuration unique to the present embodiment, but the present invention is not limited to them. The plug device may be applied to various types of electric equipment using a commercial power supply.
