Description

Description: TECHNICAL FIELD The present invention relates to a charger attachment for charging a battery having a different shape from a battery that can be directly attached to a charger using the same charger.

[Prior art and its problems]

There are many types of small rechargeable batteries centered on Ni-Cd batteries, but their shape is not uniform due to the relationship with the electronic devices used, although their charging characteristics are similar. As is clear from the example of a portable video recorder, the same manufacturer's technological change has caused remarkable changes in the shape of electronic devices in a short period of time, including miniaturization. It is also a major reason that it is necessary to successively match the shape of the device. Conventionally, in the method of using a different charger suitable for each battery of different shape or attaching the battery to the attachment connected to the charger with a cord, the attachment should be exchanged according to the shape of the battery for charging. I had to do it. Therefore, the consumer is forced to purchase a charger for each battery of the electronic device, and the method of using the cord and the attachment makes it easier to disconnect the cord, operability, and portability. It was inconvenient in that point and was not used much.

〔Purpose〕

The purpose of the present invention is to charge another battery with a different engagement part shape by attaching the attachment of the present invention to the attachment part of the dedicated charger of the battery that is directly connected to the charger to be charged. It is possible to eliminate the above-mentioned conventional drawbacks.

[Technical means for solving problems]

The charger attachment of the present invention has a mounting part for mounting a second battery, which has a different engaging part shape from the first battery, which is directly connected to and charged by a dedicated charger, and the charging battery itself. The engaging portion has an engaging portion having the same shape as that of the first battery for fixing, and the attaching portion has a contact that comes into contact with the contact of the second battery when the second battery is attached. Is provided with a contact that comes into contact with the contact of the charger when it is mounted on the charger.

〔Example〕

Hereinafter, an embodiment of the attachment for a charger of the present invention will be described with reference to FIG.

In FIG. 1, 1 is a charger, 2 is a first battery which is directly connected to and charged by the charger 1, 3 is an attachment of the present invention fixed to the charger 1, 4 is an attachment 3
It is a second battery mounted on the.

The charger 1 obtains predetermined DC power from the commercial power source connected to the outlet 5 at the contacts 6A and 6B.
A first flat surface 7 provided with B and two vertical grooves 9 provided on both side surfaces 8 at positions close to the flat surface 7.
It has a mounting portion 10 for the battery 2. The first battery 2 has a ridge 11 that fits in the vertical groove 9 and a contact that faces the flat surface 7 when fixed to the charger 1 by the vertical groove 9 and the ridge 11 and that contacts the contacts 6A and 6B. It has a flat surface 13 provided with 12A and 12B. The charger 1 is originally the first
The battery 2 is configured to charge the battery 2. Incidentally, 24 and 25 are a switch and a pilot lamp of the charger 1, respectively.

The attachment 3 is a protrusion 1 that fits in the vertical groove 9 with each other.
4, a contact 15 that faces the flat surface 7 and is in contact with the contacts 6A and 6B when being fixed to the charger 1 by the vertical groove 9 and the protrusion 14.
It has a flat surface 16 provided with A and 15B. That is, the attachment 3 can be fixed to the charger 1 in the same manner as the first battery 2, and the ridge 14 and the flat surface 16 can be fixed.
It has the engaging part 17 which consists of. Further, on the surface opposite to the engaging portion 17, a second battery having a shape different from that of the first battery 2 is formed.
It has a mounting portion 18 for the battery 4. The mounting portion 18 is
On the flat surface 21, the central ridge 19 of the second battery 4 and the vertical groove 20 that fits with each other, the contact 2 of the second battery 4
23A and 23B which contact 2A and 22B are provided. Of course, contacts 15A and 15B and contacts 23A and 23B
Are connected inside the attachment 3. And
The second battery 4 having a contact position and an overall shape different from those of the first battery 2 is attached to the attachment portion 18 of the attachment 3.
Fixed to. The cross-sections of the ridge 19 and the vertical groove 20 are shaped so as to engage with each other and do not separate.

In this way, the engaging portion 17 of the attachment 3 is attached to the charger 1 with the second battery 4 fixed to the mounting portion 18.
If it is fixed to the mounting portion 10 of the first battery 2 of
The contacts 22A and 22B of the battery 4 are connected to the contacts 6A and 6B of the charger 1 through the attachment 3 to perform charging.

And the charging of the battery that can not be directly connected to the charger,
It will be as possible as a direct connectable battery.

The attachment of the present invention is not limited to the embodiment, and it goes without saying that many modifications are involved depending on the shape of the second battery to be mounted and the shape of the mounting portion of the charger.

〔effect〕

As described above, the attachment for a charger of the present invention has the engaging portion for the charger and the mounting portion for the second battery, and the engaging portion is for connecting with the first battery directly connected to the charger. It is fixed to the mounting part of the dedicated charger. Therefore, the first
In addition to the above battery, the second battery that cannot be directly connected to the charger can be charged by simply replacing the attachment. And there is no waste of purchasing and adapting a charger for each battery, which is very economical especially for consumers. When actually selling the charger,
Multiple attachments of the present invention that are compatible with several types of batteries may be sold in combination with the charger or may be sold separately.
