In the conventional plug device as described above, the plug assembly is rotated and accommodated in a direction perpendicular to the direction in which the two plug blade bodies are arranged, so that the plug is inserted into the case. It is necessary to provide a storage space for storing the entire assembly, and there is a problem that the case becomes large accordingly.

The present invention has been made to solve such a drawback, and an object of the present invention is to provide a plug device in which a storage space for a plug blade main body is reduced.

[0006]

SUMMARY OF THE INVENTION A plug device for an electric device according to the present invention includes a pair of rectangular plate-shaped plug blade bodies disposed so as to face in parallel with each other and along one short side of each plug blade body. And a shaft portion rotatably supporting the plug blade main body, wherein each of the plug blade main bodies is in an upright state.
Can rotate in the same direction from
It is supported on the shaft portion, prior to the overlap
It is stored in the main body case .

[0007]

According to the present invention, the plug blade main body is supported by the supporting means, and is rotated and stored in the same direction, so that the storage space for the plug blade main body can be reduced.

1 to 3 show a plug device according to an embodiment of the present invention.

In this embodiment, a pair of metal plug blades 1, 1, a plastic main body case 2 for standing and storing the plug blades 1, and a movement from a transmission knob 3a are transmitted to the plug blade 1 and transmitted thereto. It is composed of a plastic transmission structure 3 to be erected and housed, and electric connectors 5 and 6 made of metal which are electrically connected to the plug blades 1 and 1 when erected.

The plug blade 1 has a plug blade main body 1a which is a rectangular plate, a shaft portion 1b located at one short side thereof, and a contact extending from the shaft portion 1b so as to form a predetermined angle with the plug blade main body 1a. 1c. And a pair of plug blades 1,
A pair of plug blade main bodies 1a, 1a of a rectangular plate are arranged so as to face in parallel in a state of standing upright from the main body case 2 for insertion into a household commercial power outlet.

The main body case 2 comprises plug blade main bodies 1a, 1a.
Is composed of a front case 2a on the side where the front case 2 stands and a rear case 2b covering the rear surface of the front case 2a. The front case 2a includes the plug blade body 1
a, a storage recess 2aa for storing a, 1a, and a transmission knob 3a
Has an opening 2ab that is exposed to the front case 2a side and can slide in the direction in which the plug blade main bodies 1a and 1a are arranged. A pair of bearings 2ac, 2ac, which are support means for supporting the shafts 1b, 1b of the pair of plug blades 1, 1, are arranged side by side in the sliding direction of the transmission knob 3a.
It is provided at the bottom of the storage recess 2aa. In addition, opening 2
On the extension line in the sliding direction of the transmission structure 3 on the side opposite to ab, a cylindrical moderation boss 2ad that regulates the movement of the transmission structure 3 when the plug blades 1, 1 are erected and stored is provided in front. It protrudes from the back side of the case 2a.

The transmission structure 3 is a roughly rod-shaped body made of plastic, having a transmission knob 3a at one end and a moderation boss 2 at the other end.
a pair of guide ribs 3b, 3
b. At the center of the transmission structure 3, a pair of transmission openings 3 into which contact pieces 1c and 1c are inserted.
c, 3c are provided side by side in the sliding direction. Moderation protrusions 3d, 3d are provided so as to face each other between the pair of guide ribs 3b, 3b at the other end.

The electrical connection bodies 5 and 6 are made of strip-shaped metal. When the plug blades 1 and 1 are erected, they are in contact with the contact pieces 1c and 1c to be electrically connected to the connection parts 5a and 6a. It comprises lead-out sections 5b and 6b for electrically connecting to electrical equipment. The electrical connectors 5 and 6 are fixed to a printed circuit board 7 disposed in the main body case 2. The printed circuit board 7 is not shown in the figure, and is electrically connected to a power supply from the plug device of the present invention. It has the electronic parts of the equipment.
Further, the plug device of the present invention may not have the printed circuit board 7 on which the electronic components of the electric device are arranged, and may be electrically connected to the electric device by a separate wiring.

Next, the operation when the plug blades 1, 1 are erected and stored will be described with reference to FIG.

First, as shown in the figure, by moving the transmission knob 3a to the right and sliding the transmission structure 3, the plug blade main bodies 1a and 1a are erected and the contact pieces 1c and 1c are connected to the connecting portions. 5a and 6a are in contact and electrically connected. At this time, the protrusions for moderation 3d, 3d
Are located on the right side of the moderation boss 2ad, and even if a force acts to move to the left side of the moderation boss 2ad, the moderation boss 2a
Since d must be overcome, the movement is suppressed.
On the other hand, even if a force acts to move to the right, the opening 2ab
The movement of the transmission knob 3a is stopped by the right side wall surface.
Therefore, the plug blade main bodies 1a, 1a are stably erected.

Next, by moving the transmission knob 3a to the left, the detent protrusions 3d 3d move over the detent boss 2ad to the left against the force of holding the detent boss 2ad. . Accordingly, the transmission openings 3c, 3c
c moves to the left and the bearings 2ac, 2a
The plug blade main bodies 1a, 1a are both rotated rightward in the drawing around the shaft portions 1b, 1b pivotally supported by c, and are partially overlapped and stored in the storage recesses 2aa as shown by dashed lines. . At this time, the contact pieces 1c, 1c are separated from the electrical connectors 5a, 6b.

[0017]

According to the present invention, the plug blade main body is supported by the support means and rotated and stored in the same direction, so that the storage space for the plug blade main body can be reduced.
