Abstract

(57) [Summary] [Purpose] To replace small dry batteries with large dry batteries. [Structure] A small dry battery (6) is placed in a case (1) having the same size and shape as a large dry battery, and a positive electrode plate (2) and a negative electrode plate (3) and a small dry battery (6) provided in the case (1). Connect each pole of. This is then used as a substitute for a large dry cell.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a dry battery adapter for using a small dry battery as a substitute for a large dry battery.

[0002]

[Prior art]

 There are different types of conventional dry batteries such as single I type, single II type, and single III type, and they have the same voltage, but the size of the main body is different.

[0003]

[Problems to be solved by the device]

 When a power outage occurs due to a disaster or the like, only the dry batteries for flashlight in the area, that is, the single I type dry battery, will be extremely insufficient. In such a case, it is difficult to use another type of dry cell as a substitute for the required dry cell because the size of the conventional dry cell differs depending on the type. The problem to be solved by the present invention is to make it possible to use other types of dry batteries as a substitute for the required dry batteries.

[0004]

[Means for Solving the Problems]

 The size of a dry battery varies depending on the type, but the voltage of a commonly used dry battery is 1. It is common at 5V. Therefore, the small dry battery (6) is placed in a case (1) of the same size and shape as the large dry battery, and the positive electrode plate (2) and the negative electrode plate (3) and the small dry battery (6) provided in the case (1). By connecting the respective poles of), the small dry cell (6) can be used as a substitute for the large dry cell. The support (5) for fixing the small dry battery (6) in the case (1) and the spring (4) for connecting the positive electrode plate (2) and the negative electrode plate (3) to the small dry battery (6) are various. It goes without saying that things can be considered.

[0005]

[Action]

 The dry battery adapter according to the present invention is used as follows. That is, the small dry battery (6) is put in the case (1) and the positive electrode (2), the negative electrode (3) and the small dry battery (6) are connected to each other. Then, it is used as a substitute for a dry cell of the same size as case (1).

[0006]

【Example】

 Example 1 FIG. 1 is a sectional view showing Example 1. The positive electrode plate (2), the negative electrode plate (3) and the spring (4) are made of electric conductors, and the positive electrode plate (2) and the negative electrode plate (3) are insulated. The spring (4) on the positive pole side may be omitted, and various shapes and materials of the spring (4) and the support tool (5) can be considered.

Second Embodiment FIG. 2 is a sectional view showing a second embodiment. The positive electrode plate (2) can be omitted by making a hole on the positive electrode side of the case (1) and projecting the positive electrode of the small dry battery (6).

Third Embodiment FIG. 3 is a sectional view showing a third embodiment. It has two small dry batteries (6) in series and is suitable for use with flashlights. Of course, three or more can be considered.

[0009]

[Effect of device]

 By using the dry battery adapter according to this invention, a small dry battery on hand can be used as a substitute for a large dry battery. For example, if the flashlight's dry batteries run out during a power outage, this dry battery adapter can surpass the situation.
