Abstract

PROBLEM TO BE SOLVED: To provide a safe plug device by folding up plug blade bodies and storing them in storage grooves on a side face of a plug case. SOLUTION: A lock button 11 of a plug case 1 is pulled by a finger in the direction of the arrow, and the plug blade bodies 2a, 2b are folded up to be stored in storage grooves 12a, 12b by letting the finger go off the lock button 11. Moreover, when the plug blade bodies are to be raised, the plug blade bodies rise automatically by the mere pulling of the lock button with the finger in the arrow direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug device used for a DC adapter or a rechargeable electric razor, and more particularly to a plug device in which a plug blade is provided directly on the main body of an electric appliance.

[0002]

2. Description of the Related Art A conventional plug device has no function of accommodating a plug blade.

[0003]

When the plug device is disconnected from the outlet, there is a danger when the plug device is dropped or stepped on because the plug blade is exposed in the conventional plug device. An object of the present invention is to provide a highly safe plug device by improving the drawbacks of the conventional plug device.

[0004]

In order to achieve the above object, a hinge is constituted by a plug blade and a terminal block, and a mechanism is provided for folding the plug blade and storing it in a storage groove on a side surface of a plug case. .

Further, a mechanism is provided in which a pinion and a rack are provided, and a pressure is applied to the plug blade by a spring, so that the plug blade and the plug blade are linked.

Further, the plug body is provided with a lock device for fixing or releasing the plug blade body. The present invention is a plug device provided with the above mechanism.

[0007]

1, 2 and 3 are external views of a plug device according to an embodiment of the present invention, and a plug case (1).
, Plug blades (2a, 3b) and lock button (1
The positional relationship of 1) is shown. 2 and 3 will not be described again and will be described with reference to FIGS. 1 and 4. FIG.

In FIG. 1, to store the plug blade in the storage groove, pull the lock button in the direction of the arrow with a finger,
When a lateral force is applied to one of the plug blades, the force is transmitted to the other plug blade and both of them fall down. If you release your finger in this state, the plug will be locked in the storage position. To return to the state shown in FIG. 1, the lock device is released by pulling the lock button in the direction of the arrow, and the stored plug blade body is raised by the force of the spring. It will be locked in the state and can be connected to the outlet. Similar to opening a jump umbrella. Fig. 4 shows the mechanism.

In FIG. 4, the plug blades (2a, 2b) and the terminal blocks (3a, 3b) are all made of metal for conduction. Leaf spring (31a, 31b) on part of terminal block
To improve continuity. The terminal block is also provided with terminal connection screws (32a, 32b).

The plug blades (2a, 2b) and the terminal block (3)
a, 3b) constitute a hinge and a torsion spring (22)
a, 22b) is pressurized in the rotation direction of the arrow. A pinion (21) is attached to the axis of the plug blade that constitutes the hinge.
a, 21b) and the rack (41) of the rack plate (4).
a, 41b). When the rack plate slides in the direction of the arrow, the pinion (21a) and the pinion (21b) rotate in reverse and interlock. This mechanism allows the plug blade to be folded.

A slide groove (42) is cut in the center of the rack plate, and a protrusion (5) of the T-type slide (5) is formed in the slide groove (42).
1) is inserted, and the transmission is changed in the direction from the rack plate to the T-shaped slide as shown by the arrow. The T-shaped slide has two key grooves, into which a slide key (6) is fitted to fix the lock device. The slide key is pressed in the direction of the arrow by the spring (8),
It is fixed to the shaft of the lock button (11) by a shaft retaining ring (7). This mechanism allows the plug blade to be fixed or released.

[0012]

The present invention is configured as described above and has the following effects.

When the plug device is not used, the danger of dropping or stepping on the plug blade body can be avoided by storing the plug blade body in the side surface of the plug body.

When packing, there is no need for a cushioning material for protecting the plug blade. In addition, there is no gap due to the plug blade, and efficient packing can be performed.

When carrying in a handbag or pocket, it is safe because the plug blade is housed.
