[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and lightweight charger used for charging a plate battery.

[0002]

2. Description of the Related Art A plate-shaped battery is used as a power source of a portable electric device which is particularly required to be thin. Plate battery 1
Reference numeral 00 denotes a plate having electrode portions 108 near both ends as shown in FIG. When charging such a plate-shaped battery 100, a charger is used.

As shown in FIG. 8, a conventional battery charger 101 used in such a case is, for example, a plate-shaped battery provided on a frame 103 provided with a plug-in plug 102 for plugging into an outlet at home fixedly protruding. A guide hole 104 for inserting the guide hole 100 is formed.
04 is provided with a charging electrode.

[0004] In order to charge, the plate-shaped battery 100 is charged after the plug 102 is inserted into the outlet or before the plug-in is inserted into the guide hole 104.

[0005]

However, the battery charger constructed as described above has a bulky structure because it has not only a large thickness but also a plug 102 which is fixed to the main body and protrudes. Inconvenient to carry. On the other hand, a plate-shaped battery is not only formed in a thin plate shape, but also made of a soft material that is easily deformed. Such a plate-shaped battery is originally set in a portable electric device, and it is usual to carry another plate-shaped battery as a spare, but as described above, the plate-shaped battery has low strength and is deformed. Therefore, a separate protective case for accommodating a spare plate battery is required to protect the battery.

As described above, when going out, it is necessary to carry a charger and a protective case for accommodating the spare plate-shaped battery in addition to the spare plate-shaped battery at the same time. There is a problem that there is. In addition, when charging a plate-shaped battery, it is necessary to insert a charger in which the plate-shaped battery is set into an outlet, but since a conventional charger has a large width, a large number of insertion holes can be inserted into one outlet. However, the number of chargers that can be plugged into the outlet is limited to one or a few, and it was impossible to charge many chargers from one outlet .

The present invention has been made in view of the above circumstances, and is small, thin, and convenient to carry, and can store a plate-shaped battery and use it as a protective case for the battery. A board that can be used as a charger for a stored plate-shaped battery, and that can be plugged into an outlet having a plurality of outlets by the number of outlets without occupying a large space It is an object of the present invention to provide a battery charger.

[0008]

SUMMARY OF THE INVENTION In accordance with this object, a plate battery charger according to the present invention has a main body capable of containing a plate battery, a lid, and a plug attached to the main body. A plate-shaped battery charger, wherein the lid is rotatably attached to the main body and is configured to be able to open and close the battery mounting surface of the main body, and the main body is provided with an upper plate opposed to the main body with a gap therebetween. The upper plate has a battery mounting surface on the upper surface, the charging electrode is exposed from the upper surface, and the lower plate is configured with a surface-mounted circuit board and the mounting surface is on the upper surface. The plug is fixed to the upper plate so as to face the plate, and the plug is rotatably mounted near the periphery of the main body in a range of 180 degrees between the protruding position and the storage position, and is stored near the periphery of the main body. Hold the insertion plug in the posture so that it does not protrude from the lower plate surface. It is characterized in that the minimum of the concave portion capable of being formed.

[0009]

When the plate battery is to be charged by the plate battery charger, the lid is opened and the plate battery is placed on the upper plate of the main body. When the lid is closed in this state, the plate-shaped battery is housed while being pressed between the lid and the upper plate of the main body. In this state, the plate-shaped battery is pushed by the lid and is in contact with the electrode exposed on the upper plate.

[0010] When charging the plate-shaped battery, the plug inserted in the recess of the main body of the charger is rotated by an arbitrary angle within 180 degrees to protrude outside the main body, and in this state, the plug is connected to the outlet. Put in. Thereby, charging of the plate-shaped battery is performed. Generally, it is best to use the plug by rotating the plug 180 degrees for the most efficient use of the outlet.

Since the charger of the present invention is thin, the thickness thereof can be made sufficiently smaller than the pitch of the plurality of outlets of the outlet. The charger can be plugged in, so that multiple chargers can be charged simultaneously with one outlet.

After charging is completed, the plug is pulled out of the outlet, and the plug is rotated by 180 degrees and stored in the recess. In this state, since the plate battery is completely housed in the charger, the charger functions as a protective case for the plate battery. The plug is housed in a concave portion having a minimum depth that does not protrude from the lower plate surface of the main body, so that the plug can be formed in a portable shape.

As shown in FIG. 4, an elastic pressing member 31 is attached to the inner surface of the top plate 6 of the lid 3, and the plate battery 100 is placed on the upper surface 14 of the upper plate 12. When the lid 3 is closed with the cover, the lid locking projection 5a is fitted into the lid locking hole 5b, the lid 3 is locked, and the pressing member 31 presses the plate-shaped battery 100 downward, and Battery 100 contacts charging electrode 22.

On the back side of the charger 1, a recess 26 is formed in the lower plate 13 as shown in FIG. This recess 26 is for accommodating the insertion plug 4,
A plug 4 is rotatably mounted. As shown in FIG. 6, the insertion plug 4 is rotatable within a range of 180 degrees, and is rotatable between a protruding posture 28a and a storage posture 28b. It can be stored so as not to protrude from the surface.

In the charger 1 having the above-described configuration, when charging the plate-shaped battery 100, the plate-shaped battery 100 is mounted on the charger 1. As shown in FIG. 4, when attaching the plate-shaped battery 100 to the charger 1, the lid 3 is opened and the plate-shaped battery 100 is placed on the upper plate 12 of the main body 2. When the lid 3 is closed in this state, the plate-shaped battery 100 is housed while being pressed between the lid 3 and the upper plate 12 of the main body 2. In this state, the plate-shaped battery 100 is pressed by the pressing member 31 of the lid and comes into contact with the charging electrode 22 exposed on the upper plate 12.

In this state, the plate-shaped battery 100 is completely housed in the charger.
Functions as a protective case for On the other hand, the plate battery 1
00, the plug 4 is stored in the recess 26 of the main body 2 of the charger 1 and is in the storage position 28b.
Is rotated 180 degrees to protrude outside the main body 2 to obtain a protruding posture 28a, and in this state, is inserted into the table tap 32 as shown in FIG. Thereby, charging of the plate-shaped battery 100 is performed.

Since the charger 1 is thin, the thickness thereof can be made sufficiently smaller than the pitch of the plurality of outlets 33 of the table tap 32. Therefore, in the outlet 32 having a large number of outlets 33, each outlet 33 Thus, the plugs 4 of the respective chargers 1 can be inserted into the chargers 1, and therefore, a plurality of chargers 1 can be charged simultaneously with one outlet.

After charging is completed, the plug 4 is pulled out of the power strip 32, and the plug 4 is rotated by 180 degrees and stored in the recess. This makes it possible to carry.
