Abstract

PURPOSE: To prevent the reverse insertion of a battery into a battery holder and prevent the leakage of liquid which may occurs during reverse contact by applying luminous paint to the positive electrode side surface and the negative electrode side surface of an exterior material for the battery. CONSTITUTION: A '+' sign and a '-' sign are shown on the positive electrode side surface and the negative electrode side surface of an exterior label for an element battery with a positive electrode 1 and a negative electrode 2, respectively, with luminous paint 3. The sign is not limited to '+' or '-' but can be marked with ○ or ▵. In this way, the reverse insertion of a battery, when specially used at a dark place, into a battery holder is prevented. In equipment for which a plural of batteries are usd, reverse contact may occurs and thus liquid may leak. The signs with the luminous paint 3 are easy to read even in the night and so there is no trouble due to connection error.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery and a battery holder for accommodating the battery in a device, which can prevent reverse connection of the battery when the battery is used in a dark environment such as in the dark.

[0002]

2. Description of the Related Art Conventionally, the positive and negative electrodes of a battery are distinguished from each other by the symbols such as "+" and "-" displayed on the outer casing and the shape of the positive electrode terminal and the negative electrode terminal. There is. Also, the method of inserting the battery into the battery holder that stores the battery in the device distinguishes between the positive electrode and the negative electrode by referring to the display in the holder.

[0003]

However, according to the conventional method for distinguishing between the positive electrode and the negative electrode, when the visibility of the place where the battery is used is poor, the symbols and the display of the positive electrode and the negative electrode displayed on the exterior material are difficult to understand. Moreover, the display of the positive and negative electrodes inside the battery holder that holds the battery is difficult to see. Especially when used in a dark place, it is very difficult to distinguish between the positive electrode and the negative electrode. Therefore, in the battery holder that holds the batteries of equipment that uses several batteries,
If the positive electrode and the negative electrode are inserted in opposite directions and the device is continuously used as it is, the incorrectly inserted battery is charged and hydrogen gas is generated, so that the internal pressure of the battery rises. Explosion-proof devices for preventing the explosion of batteries due to this increase in internal pressure have been conventionally known.

The present invention provides a battery in which a positive electrode and a negative electrode can be easily discriminated from each other even in a poor visibility condition such as darkness, and a battery holder which accommodates a battery in which the positive electrode side and the negative electrode side can be easily discriminated from each other. The purpose is to prevent.

[0005]

In order to achieve this object, the present invention provides a display capable of discriminating between a positive electrode and a negative electrode with a luminescent coating on at least one of the positive electrode side and the negative electrode side of a battery casing or a battery holder. Is to be applied.

[0006]

In the battery using the above-mentioned luminous paint, the positive electrode and the negative electrode can be easily discriminated from each other even in a situation where visibility is poor such as in the dark, and it is possible to prevent the battery from being inserted backward into the battery holder.

【Example】

(Embodiment 1) FIG. 1 shows an embodiment of the present invention. It is a battery in which an exterior label is attached to a unit cell, 1 is a positive electrode, and 2 is a negative electrode. A "+" symbol is displayed on the side of the positive electrode side of this outer label and a "-" symbol is displayed on the side of the negative electrode side by the luminous paint 3 so that the positive electrode and the negative electrode can be clearly confirmed even in the dark.

As described above, when the luminous paint is applied, the positive electrode and the negative electrode can be easily distinguished, and the battery can be used without confusing the positive electrode and the negative electrode.

FIG. 2 shows another embodiment of the present invention. An exterior label is attached as in FIG.
The “+” sign of the positive electrode is displayed on the side of the positive electrode side of the outer label with the luminous paint 3, so that the positive electrode side can be clearly confirmed.

FIG. 3 shows another embodiment of the present invention. An exterior label is attached as in FIG. The "-" sign of the negative electrode is displayed on the side of the negative electrode side of the outer label with the luminous paint 3, so that the negative electrode side can be clearly confirmed.

In the examples, the symbol "+" is used for the positive electrode side and the symbol "-" is used for the negative electrode side. However, the symbol "+" or Not limited to “−”, “◯” or “Δ” may be used as long as it is easy to distinguish between the positive electrode and the negative electrode.

FIG. 4 shows another embodiment of the present invention. The outer label of the outer label of the battery is provided with the band-shaped luminous paint 3 on its outer peripheral surface so that the positive electrode side can be easily confirmed. It is the one. The band-shaped luminous paint is not limited to the positive electrode side and may be applied only to the negative electrode side, or may be applied to both the positive electrode side and the negative electrode side if the positive electrode side and the negative electrode side have different color arrangements.

FIG. 5 shows another embodiment of the present invention. A ring-shaped luminous paint 3 is applied to the folded portion of the outer label of the battery on the positive electrode side so that the positive electrode can be easily confirmed. It is the one. The ring-shaped luminescent material may be applied only to the negative electrode side, or may be applied to both the positive electrode side and the negative electrode side as long as the positive color and the negative side luminescent material have different color arrangements.

The band-shaped or ring-shaped luminescent paint shown in the embodiments of FIGS. 4 and 5 may be dots or lines as long as the display makes it easy to distinguish between the positive electrode and the negative electrode.

Although the luminous paint in the above embodiments is applied to the exterior label, it can be applied to other exterior materials such as an exterior can and an exterior tube.

FIG. 6 shows another embodiment of the present invention. A ring-shaped luminous paint is applied to the shoulder surface of the outer periphery of the cap of the positive electrode terminal of the battery so that the positive electrode can be easily determined. It was done.

The ring-shaped luminescent paint shown in the embodiment of FIG. 6 may be “◯”, “Δ”, dots or lines as long as the display makes it easy to identify the positive electrode.

(Embodiment 2) FIG. 7 is a top view of a battery holder accommodating a battery, to which the luminescent coating 3 is applied. Even if the positive electrode and the negative electrode of the battery itself are discriminated, if the direction of the positive electrode and the negative electrode of the battery holder into which the battery is inserted cannot be confirmed, the battery may be inserted backward. By displaying the positive and negative symbols on the battery holder with a luminous paint, it is possible to confirm the insertion direction of the battery to be stored in the battery holder and prevent the battery from being inserted in the opposite direction.

Note that this display may use other symbols such as “◯” and “Δ” or the shape of the battery as long as the battery insertion direction can be clearly discriminated.

The luminescent paints used in Examples 1 and 2 are, for example, fluorescein and rhodamine.
