Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery storage device suitable for electronic devices, particularly portable devices.

Conventional battery storage devices in electronic devices are designed to accommodate batteries of different diameters, such as single and rechargeable nickel cadmium batteries, in contrast to battery storages that fit the diameter of large single cells. When using a nickel cadmium battery, a space is inevitably created, so a method of filling the space has often been to use a filler such as a sponge.

However, when using a nickel cadmium battery, a corresponding technique is required to fill the above-mentioned space and to securely hold the nickel cadmium battery in the storage section. It is necessary to store things, and in the past, there were many cases where this filling was lost.

Therefore, the present invention provides a novel battery storage device that eliminates such drawbacks, and will be described below with reference to the drawings.

Fig. 1 is an exploded perspective view of the battery storage device of the present invention for storing small-diameter batteries such as nickel-cadmium batteries, and Fig. 2 shows the storage state of the battery, where A is a plan view and B is the main part. The cross-sectional view and FIG. 3 show the storage state of a battery, such as a primary battery, which has a larger diameter than the nickel-cadmium battery, and A is a plan view and B is a sectional view of a main part.

First, to explain the case of storing a small-diameter battery such as a nickel-cadmium battery, a nickel-cadmium battery as a rechargeable secondary battery is usually arranged in a battery pack 1 as shown in Figs. 1 and 2.
In the illustrated example, three battery packs are arranged in series in two rows in parallel, and a power supply lead wire 2 is connected to the battery pack 1.
A connector 3 is provided at the end of the drawer. There is a space plate in the middle of the power lead wire 2.
They are tied together at the lead hole 5 of No. 4 . On the other hand, in a battery storage body 21 such as a cabinet, a first battery storage section 6 for large-diameter batteries and a second battery storage section 7 for small-diameter batteries are successively provided in a concave state. Terminal electrodes 8, 9 are provided for large diameter batteries.

Therefore, when the battery pack 1 is stored in the second battery storage part 7 through the first battery storage part 6 from the state shown in FIG. 1, the small-diameter batteries 10,
The bottom side of 10 comes into contact with the bottom wall of the second battery storage section 7, and the top side one is stored in the first battery storage section 6, so that the length of the small battery corresponds to that of the small diameter battery. The length of the second battery storage section 7 is set to the length of the second battery storage section 7. The connector 3 is connected to the plug 11 for predetermined connection (shown in FIG. 3A), the space plate 4 is inserted into the sliding groove 12, and the recess 13 is brought into contact with the upper surface of the battery pack 1, By covering the opening side of the first battery storage section 6 with the battery cover 14, the battery pack 1 is securely held as shown in FIG. 2B.

At this time, the claw pieces 15, 15 and the locking pieces 16, 16 of the battery cover 14 are securely attached to the periphery of the opening side 19 of the first battery compartment through the insertion holes 17, 17 and the locking holes 18, 18, respectively. is retained.

Next, to explain the case of storing large-diameter batteries, three large-diameter batteries 20 are placed in series in the first battery storage part 6 in the example shown in FIG.
An example will be shown in which six batteries are housed in a row. In this case, if the terminal electrode 9 side is short-circuited and six such batteries are connected in series, a voltage of 1.5V x 6 = 9V can be obtained. After performing the above-mentioned operation, if the opening side 19 of the first battery storage section 6 is covered with the battery lid 14 in the same manner as described above, the large-diameter batteries 20, 20, 20 can be securely held. In the example of a single battery and a nickel cadmium battery, 1.5V x 8 = 12V, 1.25V x 10 = 12.5V, respectively.
You can use 8 and 10 pieces.

Note that the above-mentioned space plate 4 can be inserted into the battery pack without being lost if the power lead wire 2 provided on the battery pack 1 is inserted into the lead hole 5 through the guide hole 21. Since it is integrated into one unit, the drawbacks of the conventional system can be prevented.

As described above, according to the present invention, both large-diameter batteries and small-diameter batteries can be stored securely in the battery compartment, and when storing small-diameter batteries, they can be easily stored by using the space plate. etc. are no longer necessary.

In order to elastically hold the battery when storing any of the batteries, an elastic member such as a spring or sponge may be fixed to the back side of the battery cover 14 and held under pressure.
