[Prior Art]

 With the recent miniaturization of electric products and the like, AA batteries are generally used for electric products that do not use a commercial power source. AA batteries are also used as power sources for small game consoles. Therefore, ordinary households are mainly equipped with AA batteries as spare batteries.

[0003]

[Problems to be solved by the device]

 However, for example, flashlights and other electrical equipment needed in emergencies require single-type batteries or AA-size batteries, and these have different sizes from AA-size batteries, so spare batteries are not available. If not, the electrical equipment could not be used.

Further, even when these batteries are always stored, since they are not used normally, they may have their life expiring without knowing them. I couldn't do it.

Further, it is wasteful to individually provide the necessary batteries.

In view of the above problems, it is an object of the present invention to provide a battery adapter that is versatile and can effectively use one type of battery.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a battery adapter according to the present invention has a bottomed cylindrical body main body in which a battery storage portion for storing at least one or more batteries is defined. And a negative electrode member that is electrically connected to the negative electrode terminal of the battery housed in one of the bottom portion and the closing member of the body body. The positive electrode member that is electrically connected to the positive electrode terminal of the accommodated battery is provided on the other bottom portion or the closing member.

A battery adapter according to a second aspect of the present invention includes a battery insertion portion for inserting a battery and a battery holding portion formed to have a predetermined thickness in a radial direction of the battery insertion portion. It is composed of a cylindrical body body, and the length of the body body in the axial direction is equal to or slightly shorter than the length of the battery inserted into the battery insertion portion.

[0009]

[Action]

 Therefore, the battery adapter according to the first aspect of the present invention can be configured as a pseudo single battery by forming the battery adapter into a substantially single battery shape that accommodates, for example, an AA battery. That is, the AA battery housed in the battery housing constitutes a pseudo single battery that can take out power from the negative electrode member and the positive electrode member, and this battery adapter has a substantially single battery shape. Therefore, it can be used in a size-appropriate manner for electric equipment for setting a single battery.

In addition, the battery adapter according to the second invention can be configured as a pseudo AA battery by forming the battery adapter into a substantially AA battery shape in which an AA battery is inserted. In other words, if the diameter of the body is the same as the AA battery and the axial length is set to be equal to or slightly shorter than the length of the AA battery and the AA battery is set in this, Since the length of the AA battery is almost the same as that of the AA battery, the positive and negative terminals of the AA battery project from the body, and a pseudo AA battery from which electric power can be taken out is constructed. The size of is defined by the body.

There is. The diameter A of the body body 2 is set to be substantially the same as the standard size of the single battery.

A spring accommodating portion 7 is formed substantially in the center of the bottom portion 5 of the body main body 2, and the accommodating AA battery 4 is attached to the spring accommodating portion 7 in the upward direction (toward the closing member 3). A biasing conductive spring 8 is stored. A thin plate-shaped conductive member 11 that contacts the negative electrode terminal 10 of the three stored AA batteries 4 is connected to one end of the spring 8 (on the side of the battery storage portion 6). A flat plate-shaped negative electrode member 13 fixed to the bottom surface 12 of the body body 2 is connected to the other end side of the spring 8 (on the bottom surface 12 side of the body body 2). Therefore, the negative electrode member 13 is electrically connected to each negative electrode terminal 10 of the AA battery 4 housed in the body 2 via the conductive member 11 and the spring 8.

Further, engaging holes 14, 14 serving as connecting means for detachably connecting the closing member 3 described below are provided at two locations on the periphery of the opening of the body body 2.

The closing member 3 is a lid-like member that closes the opening of the body 2 and is made of an insulating material such as resin, and is connected to the opening of the body 2 so as to be detachably connected. Engaging pieces 20, 20 are provided, and a boss-shaped positive electrode member 15 in which a groove 15a is formed is fitted in substantially the center thereof. The closing member 3 may be fixed to the opening of the body 2 so as to be openable and closable via a hinge or the like.

To this positive electrode member 15, for example, a thin conductive member 18 bent and fixed to a holding member 17 is connected via a conductive wire 16, and the conductive member 18 is housed in the body body 2. The positive electrode terminals 19 of the AA battery 4 are contacted. Therefore, the positive electrode member 15 is electrically connected to each positive electrode terminal 19 of the AA battery 4 housed in the body body 2 through the conductive member 18 and the lead wire 16.

The total height B of the battery adapter 1 when the closing member 3 is attached to the body 2 is set to be substantially the same as the standard size of the single battery.

In the battery adapter 1 having the above configuration, when the AA batteries 4 are housed in the body body 2 and the closing member 3 is attached, the negative electrode terminal 10 and the positive electrode terminal 19 of each AA battery 4 become conductive. They are connected in parallel via the members 11 and 18, and are electrically connected to the negative electrode member 13 and the positive electrode member 15, respectively. The shape of the battery adapter 1 is substantially the same as that of the single battery as described above.

Therefore, the battery adapter 1 accommodating this AA battery 4 constitutes a pseudo single battery in which electric power can be taken out from the negative electrode member 13 and the positive electrode member 15, and can be used as an AA battery. It can now be used with electrical equipment that uses a single battery as its power source.

Further, even if the AA battery used is a manganese battery, it can be connected in parallel, so that the structure has a capacity similar to that of an alkaline battery, so that it can handle a heavy load. Is becoming Further, as shown in FIG. 3, if the partition 25 is used, the battery adapter 1 according to the present application can be used even with one AA.

Next, an embodiment of the battery adapter according to the second invention will be described with reference to FIG.

It is composed of a substantially cylindrical body main body 23 composed of a holding portion 22 and is adapted to form a pseudo AA battery by using the AA battery 4. The material of the body body 23 is an insulating material such as resin. The diameter C of the body 23 is set to be substantially the same as the standard size of the AA battery, and the axial length D is set to be shorter than the length of the AA battery 4. The negative electrode terminal 10 and the positive electrode terminal 19 project from the body 23.

That is, when the AA battery 4 is set in the battery adapter 20, the negative electrode terminal 10 and the positive electrode terminal 19 of the AA battery 4 project from the body main body 23, and therethrough like the AA battery. The power can be taken out. This is because the total height of the AA battery and the AA battery is almost the same, and there is no problem in using. Since the diameter of the body 23 is set to be substantially the same as the standard size of the AA battery, the size in the radial direction is defined to be the same as that of the AA battery. As a result, by simply setting the AA battery in the battery insertion portion 21, the AA battery can be easily used in correspondence with electrical equipment using the AA battery as a power source. If the AA battery used is an alkaline battery, it has the same capacity as the AA battery, so its performance does not change.
