Description

[Detailed Description of the Invention] This invention relates to a battery storage device for, for example, a portable radio.

In general, various types of batteries, such as dry batteries and NiCd batteries, with different shapes and sizes are commercially available. Among the various types of batteries mentioned above, only specified batteries can be used in the portable radio and the like. The battery storage device in this case is configured as shown in FIGS. 1 to 3, for example. In the figure, 1 is the main body of the device, and a positive electrode 3 is provided on one end wall of a storage recess 2 bored in the main body.
However, a spring 4 which also serves as a negative electrode is fixed to the other end wall. Dry batteries 5a, 5b, and 5c are housed in the recesses and are connected in series, with the positive electrode of the battery 5a connected to the electrode 3, and the positive electrode of the battery 5c connected to the electrode 3.
The negative electrode of is in contact with the spring 4. With the batteries 5a, 5b, and 5c housed in this manner, the opening of the recess 2 is covered with a lid (not shown), so that the housed batteries 5a, 5b, and 5c are configured not to fly out from the recess 2. has been done.

Conventionally, as shown in FIG. 4, as a charger, the main body 1 is provided with separate storage recesses 2a, 2b, and 2c of different shapes and sizes, and these are provided with storage recesses 2a, 2b, and 2c for storing batteries of different shapes and sizes. It is known that it can store . In the figure, 3a, 3b, 3c
4a, 4b, and 4c are springs.

In this way, by providing different storage recesses for each type of battery, any of the various types of batteries can be used.

By the way, in order to make the space occupied by the battery storage recess smaller than that of the one shown in FIG. 4, a relatively large first recess is used, as partially shown in FIGS. A first storage recess 2 that stores batteries 5a, 5b, and 5c, and a relatively small second battery 6 disposed deep inside the first storage recess.
A, 6b, and 6c are provided with a second storage recess 7 for storing the batteries, and the first battery stored in the first storage recess also reaches the second storage recess and is also stored in the second storage recess. A battery storage device may be considered in which the first storage recess and the second storage recess are arranged so that the second battery also extends to the first storage recess, so that the first storage recess and the second storage recess partially share the same space.

In the battery storage device configured in this way, the first
By providing a lid to cover the storage recess, it is possible to prevent the first battery from flying out of the storage state, but it is not possible to provide a lid to cover the battery insertion opening of the second storage recess. Therefore, there is a drawback that it is not possible to prevent the second battery from flying out.

This invention eliminates the above-mentioned drawbacks, and as shown in FIGS. At the edge of the opening for insertion, second batteries 6a, 6 stored in the second storage recess 7 are provided.
Elastic protrusions 10a, 10 to suppress protrusion of b, 6c
This is a battery storage device provided with battery storage devices b and 10c.

An embodiment of this invention will be described below with reference to the drawings. 5 to 9, reference numeral 1 denotes the above-mentioned main body, and the main body includes the above-mentioned batteries 5a, 5b,
5c, and below the storage recess, other batteries 6a, 6b, 6 are connected continuously to the storage recess.
Another storage recess 7 is formed to store c.
Reference numeral 4 designates the above-mentioned spring, and reference numeral 8 designates a spring that also serves as an electrode, and is configured to be in contact with the negative electrode of the battery 6c. Reference numeral 9 denotes an electrode fixed to the main body 1, which is commonly used with which the positive electrodes of the batteries 5a and 6a are brought into contact. Reference numerals 10a, 10b, and 10c are elastic protrusions formed integrally with the main body 1, and these protrusions allow the batteries 6a, 6 housed in the recess 7 to
This is to prevent b and 6c from flying out from here. These protrusions 10a, 10b, 10c are made against their elasticity when inserting or removing the battery.

As shown in FIG. 7, the recesses 2 and 7 have open upper surfaces (the widths of the recesses 2 and 7 are as shown in FIG. 7).
...), a vertical wall is formed from these open edges, and a semicircular surface is formed following this wall along the outer periphery of the batteries 5a, ..., 6a, ... to be stored. , of the semicircular surface, the recess 2
The upper surface open portion of the above-mentioned recess 7 is formed in it. A part of the bottom surface of the recess 2 that actually disappears due to the opening of the recess 7 is connected to the recesses 2 and 7 so that it reaches inside the battery when the battery 6a,... is stored in the recess 7. The positional relationship of

Incidentally, the above-mentioned lid is provided on the open upper surface of the recess 2, and the batteries 5a, . . . are maintained in a stored state by the lid.

In the above embodiment, the positions of the recesses 2 and 7 were determined so that the axis of the recess 2 (the axis of the housed batteries 5a, . . . ) and the recess 7 coincided with each other when viewed from above. 11 or 12, the above-mentioned axis line may be shifted to make one of the vertical wall surfaces continuous with respect to the recesses 2 and 7, thereby making the above-mentioned continuity of the main body 1. When the outer surface 11 of the main body 1 is on the side with which the main body 1 is formed, a large space can be taken up on the other side 12, and other devices, such as a printed circuit board, etc., can be arranged in this space. In FIGS. 10 to 12, the same reference numerals as in FIGS. 5 to 9 indicate the same elements. Reference numeral 3 indicates the electrode described above; 13 indicates an electrode for the battery 6a similar to the electrode; 14 indicates a spring fixed to the main body 1; An electrode 15 that can be brought into contact with the negative side of is integrally fixed.

Further, in the above embodiment, the elastic protrusions 10a, 10b,
10c, but among these protrusions, for example, 1 is provided so that a single battery can be inserted.
Battery 6 is made with only 0a being elastic and the others being inelastic.
It is also possible to insert 6c and 6b in sequence from the position where a is stored, slide them in the recess 7, and finally insert the battery 6a. In this case, the first
As shown in FIG. 3, an inelastic protrusion 10d may be provided instead of the protrusions 10a and 10b.

As mentioned above, this idea is based on a relatively large first
A first storage recess 2 that stores batteries 5a, 5b, 5c, and a second storage recess 2 that stores relatively small second batteries 6a, 6b, 6c, which is disposed deep inside the first storage recess. A storage recess 7 is provided, and the first battery stored in the first storage recess also reaches the second storage recess,
Further, the second battery stored in the second storage recess extends to the first storage recess, and the first storage recess and the second storage recess are arranged so that they partially share the same space with each other. In the battery storage device, a second storage recess is provided at the edge of the battery insertion opening of the second storage recess provided on the bottom surface of the first storage recess.
This battery storage device is characterized by being provided with elastic protrusions 10a, 10b, and 10c that prevent the second battery stored in the storage recess from popping out, and the second battery is prevented from popping out with a simple configuration. can do.
