Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a battery holding device in which dry batteries are arranged in parallel and can be electrically connected in series.

(Prior art) Conventionally, a positive terminal and a negative terminal are provided on one side of a single electrode plate, and the plates are fixed facing each other, thereby fixing the batteries in parallel and electrically connecting them in series. A device (for example, Japanese Utility Model Application Publication No. 56-78158) is generally known. In this battery holding device, the insertion direction of the electrode plate when fixing the electrode plate to the battery holding device is determined. Therefore, by fixing the positive and negative terminals of the electrode plates facing each other, it is possible to easily provide a 3V power source by arranging two 1.5V batteries in parallel.

(Problem to be solved by the invention) When arranging three 1.5V batteries in parallel and electrically connecting each battery in series to provide a 4.5V power source,
As shown in FIG. 5, two types of multipolar plates 2 and 8 and two types of monopolar plates 4 and 6 were required. That is, the electrode plate 2 is provided with a positive electrode terminal A on the left side and the negative electrode terminal B on the right side when viewed from the battery housing side, the electrode plate 4 is provided with only the positive electrode terminal A, and the electrode plate 6 is provided with a negative electrode terminal A. Only the terminal B is provided, and the electrode plate 8 is provided with the negative electrode terminal B on the left side and the positive electrode terminal A on the right side when viewed from the battery storage section side.

The purpose of the present invention is to enable the electrode plate 2 and the electrode plate 8 to be constructed from the same electrode plate in the battery holding device shown in FIG. 5, thereby reducing the number of parts. Another purpose is to enable positioning of the electrode plate provided with the positive and negative terminals using the negative terminals themselves.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a battery holding device capable of holding at least three dry batteries in parallel, which has a positive electrode terminal and a negative electrode terminal having a tongue-like elastic portion on the surface. At least two multipolar plates arranged in parallel and each having a positive terminal and a negative terminal provided on the back surface by rotating each polar terminal on the front side by 180 degrees parallel to the surface; A vertical groove is provided which is connected to the fixing groove in which the positive electrode terminal and the negative electrode terminal are inserted, and a vertical groove in which the positive electrode terminal is protruded and fixed to the battery housing side, and the negative terminal is elastically coupled. and a stepped portion provided near the battery insertion opening of the back wall, with which the tip of the tongue-like portion of the negative electrode terminal comes into contact to position the multipolar plates, and the two multipolar plates is characterized in that a positive terminal and a negative terminal are arranged opposite each other, and that it is possible to electrically connect batteries arranged in parallel in series using one type of multi-polar plate.

(Example) FIGS. 1 to 4 show an example of a battery holding device according to the present invention. 3 and 4 show a multipolar plate 10 according to the present invention, in which a negative electrode terminal 14 consisting of a tongue-shaped portion and a positive electrode terminal 16 consisting of an annular raised portion are provided on the front side 12. A positive terminal 20 and a negative terminal 22 having the same shape as the positive terminal 16 and negative terminal 14 are provided on the back side 18.
A negative terminal 22 is arranged directly behind the positive terminal 16, a positive terminal 20 is arranged directly behind the negative terminal 14, and the negative terminals 14, 22 are connected from the side of the multipolar plate 10 as shown in FIG. As you can see, it is set in a Z-shape.

FIG. 1 shows a battery holding device 30 to which a multipolar plate 10 and monopolar plates 24 and 26, which are constructed by separating the multipolar plate 10, are attached. The monopolar plate 24 is used as the positive terminal 16, and the monopolar plate 26 is used as the negative terminal 14.
It is used as. The two multipolar plates 10 and each monopolar plate 24, 26 have respective fixing grooves 36, 38, 40,
42, each pole terminal 14, 16, 20, 2
2 are vertical grooves 44, 4 connected to the fixing grooves 36 to 42;
6, 48, 50, 52, 54 to battery storage section 3
2, 33, and 34.

A vertical groove 44 in which each positive electrode terminal 16, 20 is fixed,
48 and 52 have negative terminals 14 and 22 as shown in FIG.
A back wall 60 is provided to which the back wall 6 can be elastically coupled.
A step portion 62 is provided above 0. The tip portions of the negative electrode terminals 14 and 22 come into contact with the stepped portion 62 and have the role of positioning the multipolar plate 10 so that it does not come off from the fixing grooves 36 and 40. In addition, monopolar plate 2
4 and 26 have the same shape and are one type of monopolar plate.

(Effect of the invention) The multi-polar plate according to the invention has a positive terminal and a negative terminal on the surface, and on the back surface of each polar terminal, each polar terminal is obtained by rotating the surface 180 degrees parallel to the surface. Since each electrode terminal is provided with the same arrangement and shape as that of It is now possible to assemble. As a result, the number of parts can be reduced, and since the electrode plate is positioned using the negative electrode terminal, it is possible to prevent assembly errors such as assembling with the same electrode terminals facing each other.
