JPH07105923A - Battery accommodation device - Google Patents

Abstract

PURPOSE:To provide a battery accommodation device of such a construction that two or more dry cells are set in series, wherein leakage of an electrolytic solution likely when dry cells are set in opposite polarization is precluded and associate damage due to contamination of the appliance which uses the dry cells is prevented. CONSTITUTION:A battery holder 1 contains a plurality of dry cells, and a cell restricting plate 5 is installed at the plus side of a contact terminal 2 of the battery holder 1 and the boundary between two cells, wherein the plate 5 is made of insulative substance and has a hollow part greater than the outside diameter of the positive electrode terminal 3 of each dry cell and smaller than the outside diameter of the negative electrode terminal 4 in such a way as facing the terminal surface of the dry cell. When dry cells are set oppositely, the plate 5 shuts the contact of the negative electrodes each other of the cells.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery accommodating device for preventing liquid leakage caused by reverse connection of dry batteries and damage caused by electrolyte contamination of equipment using dry batteries caused by the leakage.

[0002]

2. Description of the Related Art Generally, a battery storage device for a device using a dry battery has only positive and negative contact terminals.
The mechanism does not prevent contact between the negative electrodes of the dry battery, that is, reverse connection.

FIG. 1A shows an example of a normal storage state of a dry battery in a conventional device. Contact terminals 2 are fixedly provided on both sides of the battery holder 1, and three dry batteries are accommodated in series between these terminals in a permuted state.

[0004]

However, in the above-described conventional structure, the battery storage device for a device using a plurality of in-series dry batteries has one of the loaded dry batteries as shown in FIG. 1 (b). When the device is activated by loading the
The reverse-loaded dry battery is charged by another normally-loaded dry battery and exhibits a phenomenon of liquid leakage.

An object of the present invention is to prevent liquid leakage due to the above-mentioned misuse of dry batteries and damage to the equipment due to the liquid leakage.

[0006]

In order to achieve the above object, the battery accommodating device according to the present invention is a battery in which two or more dry batteries are loaded in series in a battery holder having positive and negative terminals. In the storage device, at least one of the boundary portion between the dry batteries in the battery holder and the positive side of the contact terminal of the battery holder has a hollow portion larger than the outer diameter of the positive electrode terminal of the dry battery and smaller than the outer diameter of the negative electrode terminal of the dry battery. And a battery control portion made of an insulating material is provided so as to face the terminal surface.

[0007]

In the battery accommodating device provided with the battery regulating portion as described above, even if the dry batteries are loaded in reverse, the contact between the negative terminals of the dry batteries or the positive side of the contact terminals is prevented, and It is possible to prevent problems.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings.

In the battery holder 1 shown in FIG. 2, the boundary between the dry batteries and the plus side of the contact terminal 2 of the battery holder 1 are larger than the outer diameter of the positive electrode terminal 3 of the dry battery and larger than the outer diameter of the negative electrode terminal 4. By providing a battery regulation plate 5 which is a battery regulation part made of ABS resin having a shape shown in FIG. 3 and which has been subjected to a small hole processing, when the negative electrode terminals and the positive electrode terminals of the dry batteries are alternately loaded in sequence, the battery regulation plate is formed. 5, the negative terminal 4 of the dry battery (A) 6 and the dry battery (B)
7 can be contacted with the positive electrode terminal 3, but a dry battery (B)
When 7 is reversely loaded, the battery control plate 5 prevents the negative terminals of the dry batteries from contacting each other, the device is not operated, and the reversely loaded dry battery is not charged.
No liquid leakage phenomenon occurred.

[0010]

As described above, the battery accommodating device according to the present invention can prevent the leakage of the dry cell due to the reverse loading of the dry cell and the damage to the equipment using the dry cell due to the leakage.
