Description

[Detailed explanation of the invention] [Industrial application field] This invention is used in portable radio cassette tape recorders, handheld computers, LCD TVs, etc.
The present invention relates to a battery storage device for an electrical device using a battery as a power source.

[Conventional technology]

2. Description of the Related Art Conventionally, in electrical equipment using batteries as a power source, a rechargeable battery having the same shape as a dry battery has been used in a battery storage section.

FIG. 7 shows this type of battery storage device, in which, for example, four rechargeable batteries 3 such as Ni-Cd batteries having the same shape as a cylindrical dry battery are arranged in a battery storage part 2 of an electrical device 1. I'm trying to make it possible.

In this case, an anode contact 4 is arranged in parallel at a position corresponding to each battery 3 on one side of the storage section 2, and a cathode contact is arranged in parallel at a position corresponding to each battery 3 on the other side, so that when the battery is stored, As shown in FIG. 8, each battery 4 is connected in series by a lead wire 5 inside the device 1. As shown in FIG.

However, in the above-mentioned device, when recharging the rechargeable battery 3 after discharging it, it is necessary to separate the batteries 3 individually and charge them using an existing charger, which makes handling difficult. There is a possibility that it will be inserted backwards during insertion.

On the other hand, Special Publication No. 56-9788 (H01M 6/44)
shows a device in which a plurality of batteries are housed in a special package and the package is housed in a device.

In this type of battery storage device, by devising the shape of the package itself, it is possible to prevent reverse insertion into the device, and when rechargeable batteries are stored in the package, it is also possible to charge each battery while it is stored in the package. However, this method requires a special package, and furthermore, the storage space on the device side is large and has a special shape, resulting in high costs.

Therefore, for example, as seen in Japanese Patent Application Laid-Open No. 52-25238 (H01M 6/42), a plurality of batteries are arranged side by side and the contact parts between the batteries are fixed with adhesive. It is conceivable to store a battery pack made up of a plurality of batteries in a battery storage section of an electrical device.

In this case, if each battery is a rechargeable battery that has the same shape as a dry battery, the battery compartment can be configured to store both dry batteries and rechargeable batteries, increasing compatibility. The structure of the section will also be simpler.

[Problem that the invention attempts to solve]

However, as mentioned above, when a battery is constructed by integrating multiple rechargeable batteries in parallel, each rechargeable battery in the battery is recharged and then stored in the battery compartment. In this case, there is a risk of reverse insertion, which is inconvenient.

This invention was made with the above-mentioned points in mind, and it is possible to reliably prevent the reverse insertion of an assembled battery made up of a plurality of rechargeable batteries into the battery compartment, and at the same time, to prevent this reverse insertion. It is an object of the present invention to provide a battery storage device that can also be used to charge rechargeable batteries.

[Means for solving problems]

Next, the configuration of this invention will be explained using FIG. 1 which corresponds to an embodiment.

The battery storage device according to this invention has an assembled battery 6 formed by arranging a plurality of rechargeable batteries 7a to 7d of the same shape as cylindrical dry batteries in parallel, and bonding the rechargeable batteries 7a to 7d to each other, and A protrusion 11 for preventing reverse insertion, which is fixed in the valley between the two matching rechargeable batteries 7c and 7d and protrudes in a direction perpendicular to the direction in which the rechargeable batteries 7a to 7d are arranged side by side; A battery storage section 14 that is recessed and stores a plurality of the dry batteries or the assembled batteries 6, and the battery storage section 1.
4 and a recess 16 into which the protrusion 11 of the assembled battery 6 stored in the storage section 14 is inserted.

The protruding part 11 is made of a metal rod 10, and the base of the protruding part 11 is electrically connected to the terminal of one rechargeable battery, and the protruding part 11 is inserted into the recess 16 of the battery storage part 14. A contact charging contact is provided.

[Effect]

Therefore, the assembled battery 6, which is made up of a plurality of rechargeable batteries 7a to 7d arranged side by side and glued together, can be used only when correctly stored in the battery storage section 14 of the electrical equipment 13.
Since the protrusion 11 is inserted into the recess 16, reverse insertion of the assembled battery 6 is reliably prevented.

In addition, the rechargeable batteries 7a to 7d are connected to the assembled battery 6.
Since the batteries can be handled as a unit, the operation of storing and removing batteries from the battery storage section 14 is simplified, and since each of the rechargeable batteries 7a to 7d constituting the assembled battery 6 is compatible with dry batteries, Dry batteries and assembled batteries 6 as power sources for electrical equipment 13
Either of these can be applied.

Further, by inserting the protrusion 11 into the recess 16, the terminal of the rechargeable battery 7d and the charging contact are electrically connected, and charging becomes possible.

〔Example〕

Next, this invention will be described in the first part showing its practical example.
This will be explained in detail with reference to FIGS.

First, Figures 1 to 5 show the first embodiment.
The diagram will be explained.

In these drawings, 6 is an assembled battery, and as shown in FIG. 2, four rechargeable batteries 7 are connected.
It consists of a to 7d.

Each of the rechargeable batteries 7a to 7d is formed in the same shape as a cylindrical dry battery, and is constructed by covering the outer peripheral surface of the battery body with an insulating heat shrink tube. In the batteries 7a to 7c, only the anode terminal 8 and the cathode terminal 8' at both ends are exposed from the tube, and the other fourth battery 7d has both terminals 8,
Not only the cathode terminal 8' but also the outer peripheral surface on the cathode terminal 8' side are exposed from the tube, forming an auxiliary charging cathode terminal 8''.

These batteries 7a to 7d are arranged side by side in the left and right direction, and the contact portions between each battery are bonded with adhesive 9.
The assembled battery 6 of the integrated battery row is constructed by fixing the battery 7d at the rightmost side.

Reference numeral 10 denotes a metal rod, which is fixed to the upper surface of the valley between the third and fourth batteries 7c and 7d in the assembled battery 6 with the adhesive 9. At the tip of the metal rod 10, each battery 7a to 7d is fixed. A protruding portion 11 for preventing reverse insertion and for a charging terminal is formed so as to protrude in a direction perpendicular to the direction in which the terminals are arranged in parallel, that is, in a rearward direction.

As shown in FIG. 3, the base of this metal rod 10 faces the auxiliary cathode terminal 8'' of the fourth battery 7d,
The two are electrically connected via a lead plate 12 spot welded between them.

Reference numeral 13 denotes an electrical device using a battery as a power source; 14 is a battery storage section which is recessed in a suitable position of the device 13 and stores four dry batteries or the assembled battery 6;
Each dry battery or each battery 7 on the rear and front sides of 4.
Four anode contacts 15 and four cathode contacts (not shown) are arranged in parallel, corresponding to the anode terminals 8 and cathode terminals 8' of a to 7d, respectively.

Reference numeral 16 denotes a recess formed on the upper surface of the rear edge of the storage section 14, which is located between the anode contacts 15 corresponding to the third and fourth batteries 7c and 7d, and is located between the assembled batteries 6.
When the protrusion 11 is correctly stored in the storage portion 14, the protrusion 11 is inserted into the recess 16.

A charging contact 17 is provided on the bottom surface of the recess 16 with which the protrusion 11 comes into contact when the protrusion 11 is inserted, and is connected to a charging circuit provided within the electrical device 13 .

When the assembled battery 6 is correctly inserted and stored in the battery storage section 14 as shown in FIG. It contacts the cathode contact, and the protrusion 11 is inserted into the recess 16 and contacts the charging contact 17.

At this time, each rechargeable battery 7a to 7d of the assembled battery 6
As shown in FIG.
and the negative side power supply terminal 20.

Therefore, when storing the battery pack 6 in the battery storage section 14, if you try to insert it backwards, the battery pack 6 will be damaged.
The protruding portion 11 comes into contact with the periphery of the storage portion 14 and prevents its insertion, thereby reliably preventing reverse insertion.

Further, when the assembled battery 6 is stored in the storage section 14 and needs to be recharged due to discharge of each of the rechargeable batteries 7a to 7d, the assembled battery 6 is Each of the rechargeable batteries 7a to 7d can be charged in the stored state.

Of course, it is also possible to use the electrical equipment 13 by arranging and storing normal dry batteries in the battery storage section 14.

Next, FIG. 6 showing the second embodiment will be explained.

In this embodiment, a metal rod 10 fixed to the valley between the third and fourth rechargeable batteries 7c and 7d of the assembled battery 6 is connected to the auxiliary cathode terminal 8'' of the fourth battery 7d.
At the same time, a protrusion 11 is formed on the metal rod 10 that protrudes forward from the assembled battery 6, so that when the assembled battery 6 is correctly inserted into the front upper surface of the battery storage section 14 of the electrical equipment 13, A recess 16 into which the protrusion 11 is inserted is formed, and a charging contact is provided in this recess.

In this case, compared to the first embodiment, the rechargeable battery 7
Although a to 7d are arranged in reverse, electrical equipment 13
Inside, wiring is made to connect the batteries 7a to 7d in series, and the anode contact 15 facing the anode terminal 8 of the first battery 7a is connected to the positive power terminal 19.
The cathode contacts opposite to the cathode terminal 8' of the fourth battery 7d are connected to the negative power terminal 20, respectively.

Therefore, in the case of this embodiment, the same functions and effects as described above are obtained, and the metal rod 10 can be made shorter.

[Effect of idea]

As described above, according to the battery storage device of this invention, a plurality of rechargeable batteries are arranged side by side and integrated to form an assembled battery, and this is stored in the battery storage section of an electrical device, so it is easy to charge. Type batteries can be handled as assembled batteries, making it easier to store and take them out of the storage compartment.Furthermore, there is no need to use a conventional package cage, making it cheaper, and the battery compartment has a special structure. It can also be used with regular dry batteries, which has the effect of expanding the range of applications.

Furthermore, since the protrusion provided on the assembled battery is inserted into the recess when the assembled battery is correctly inserted into the battery compartment, reverse insertion of the assembled battery can be reliably prevented with a simple configuration. There is no need to use it, and the effect is that it is easy to handle.

At the same time, by inserting the protrusion into the recess, the terminal of the charging battery and the charging contact are electrically connected, and charging becomes possible.

Therefore, the reverse insertion prevention protrusion can have two functions: prevention of reverse insertion and charging, and the configuration of the rechargeable battery and the battery storage section can be further simplified.
