Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in battery storage devices for devices that use batteries, such as radios and tape recorders.

As shown in FIG. 1, a battery storage recess 3 is provided in the main body 1 of the device, in which a plurality of batteries 2a, 2b, 2C, 2d, for example, 2 batteries, are installed vertically in parallel with each other, with the polarities in the same direction. There is something set up.

It is preferable to align the polarities of the batteries in the same direction in this way, since it prevents the batteries from being installed in the wrong direction.

To connect the four batteries 2 a , 2 b , 2 C, and 2 d in series, as shown in FIG. 2, four positive terminals A, B, C, D and four negative terminals E, F, Just connect G and H.

In the same figure, the bold lines are the four batteries 2a, 2b, 2C, 2d.
The thin lines indicate the wiring between the terminals.

Generally, the negative terminal E disposed in this kind of battery storage recess 3
, F, G, and H are composed of coil springs, and the spring properties of the coil springs maintain the contact state when the battery is installed, so the distance between the tip of the coil spring and the positive terminal (generally a plate terminal) is It is narrower than the longitudinal dimension of the battery.

Therefore, when a battery is inserted and mounted between the positive and negative terminals connected as described above, there is a risk that the positive and negative electrodes of the battery may short-circuit between the terminals due to the following combination.

If there is even one combination that is defective in this way, the terminals may be short-circuited and the battery may generate heat, which is undesirable.

The present invention has been proposed in view of this point, and is designed to prevent the above-mentioned combinations that result in terminal short circuits from occurring.

FIG. 3 shows a perspective view of the device of the present invention, and the same parts as those of the conventional device shown in FIG. 1 are given the same figure numbers.

A particular feature of the present invention is that vertical ribs 4, 4 are provided in the battery storage recess 3 to align the batteries 2a, 2b, 2C, and 2d in two pairs, one above the other, and two vertical ribs are provided in the battery storage recess 3. The point is that a horizontal rib 5°5.5 is provided in a part of the storage opening 3'.

The ribs 5, 5.5 are arranged on the negative electrode terminals E, F, G, and H sides.

Therefore, if you try to insert the battery diagonally as shown by the chain line in Figure 4, the ribs 4, 4 will prevent you from inserting it, and if you try to insert the battery diagonally as shown by the chain line in Figure 5. In this case, the rib 5 will prevent the insertion.

Therefore, in the table above, short circuits between terminals C and E, short circuits between terminals C and F, short circuits between terminals B and E, and short circuits between terminals G and C can be prevented.

In addition, 6 in the figure is a ribbon for taking out the battery.

As described above, the device of the present invention is equipped with a battery storage recess into which four batteries are installed vertically and parallel to each other with polarity in the same direction, and four positive electrodes are installed at one end of the battery storage recess. 4 with a terminal and each consisting of a coil spring on the other end side.
A battery storage device configured to connect each battery in series by providing two negative electrode terminals, wherein a vertical rib is provided in the battery storage recess for arranging each battery two at a time, two above the other, and the battery storage Horizontal ribs are provided in the storage opening on the negative terminal side of the recess, and each rib is configured to prevent terminal short-circuiting when each battery is inserted.
It is possible to easily prevent batteries from generating heat due to defective terminal short-circuits, and it is practically useful as a battery storage device in which batteries are stored with their polarities aligned in the same direction.
