Abstract

PURPOSE:To surely separate batteries or make them uninsertable and prevent the contact between electrodes when the batteries are inserted in opposite directions by providing notch sections penetratable by the positive protruded electrodes of the batteries on partition walls of a battery storage body. CONSTITUTION:Notch sections 3 penetratable by the positive protruded electrodes of batteries are provided on partition walls 2 of a battery storage body, and notch sections 3 penetratable by coil springs of an apparatus brought into contact with the positive protruded electrode and a negative electrode are provided on walls 2a at both end sections of the storage body 1. When the batteries are regularly inserted into the storage body 1, the positive protruded electrodes penetrate the notch sections 3 of the partition wall 2, and the adjacent batteries are correctly connected together in series. When the batteries are inserted in opposite directions with the negative electrodes faced to each other, the negative electrodes can not penetrate the partition walls 3, and the adjacent batteries are not connected to each other. When the batteries are inserted with the positive protruded electrodes faced to each other, the positive protruded electrodes are overlapped, and the batteries can not be inserted. When the batteries are inserted in opposite directions, the contact is prevented, and the leakage of the batteries can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery housing, and more particularly to a battery housing for preventing reverse battery connection of equipment powered by a battery.

[0002]

2. Description of the Related Art Conventionally, prevention of reverse battery connection of this kind of equipment is disclosed in Japanese Patent Laid-Open No. 60-109168 and Japanese Utility Model Laid-Open No. 63-7.
As disclosed in Japanese Patent No. 2850, a plurality of cylindrical batteries are housed in a straight line, having a connection terminal that comes into contact with a battery electrode.
When the batteries are inserted backward by the partition wall that separates each battery −
The electrodes are isolated to prevent reverse connection. However, the reverse insertion of the + electrodes showed an anomaly due to the overlapping of the + electrodes, but the contact between the + salient electrodes could not be prevented.

[0003]

The conventional one cannot be used, for example, in a portable electric lamp having a cylindrical battery housing.

The present invention solves this problem. Even if the negative electrodes of a battery are inserted so as to be connected to each other, the two are surely isolated from each other, and even if an attempt is made to insert so that the positive electrodes are connected, an abnormality is signaled. Another object of the present invention is to provide a battery housing that is not easily connected.

[0005]

To achieve this object, the battery housing of the present invention is integrally formed of a sheet-shaped insulating material for linearly housing a plurality of cylindrical batteries and connecting them in series. A battery housing which is made of a tubular body and which can take in and out a battery in a direction perpendicular to the central axis of the tubular body from above the opening of the tubular body, and a battery housing portion for housing each battery, A battery holding portion that holds more than half of the battery outer periphery and a partition wall that partitions each of the batteries are provided on the upper portion of the battery housing portion, and the partition wall includes a cutout portion through which a + projection electrode of the battery can penetrate. The walls at both ends of the housing have + projecting electrodes and −
It is provided with a cutout portion through which a coil spring of a device that abuts the electrode can penetrate.

[0006]

With this configuration, when the battery is properly inserted into the battery housing, the + projecting electrode penetrates the notch of the partition wall,
The adjacent batteries will be normally connected in series.

On the other hand, when the-electrodes of the adjacent batteries are inserted so as to face each other, the-electrodes cannot penetrate the notch of the partition wall, so that the adjacent batteries are not connected to each other. Also, when trying to insert the + projecting electrodes of the adjacent batteries in a direction in which they face each other, the + projecting electrodes of the adjacent batteries overlap each other and the battery cannot be inserted into the battery accommodating section, so an error is reported and the + projecting electrodes also contact each other. It can be prevented.

Although the opening of the battery holding portion is narrower than the diameter of the battery, the battery housing is made of a sheet-shaped insulating material and has flexibility, so that the opening is momentarily wide when the battery is taken in and out. The battery can be deformed and the battery can be easily taken in and out. Further, after the batteries are inserted, the plurality of batteries can be linearly held in the one battery housing by the battery holding portion, and the plurality of batteries can be handled like one battery.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A battery housing according to an embodiment of the present invention will be described below with reference to the drawings. 1 to 4, a battery housing 1 (storing a plurality of cylindrical batteries linearly and connected in series) is a cylindrical body integrally formed of a sheet-shaped insulating material. The battery 5 can be taken in and out from above the opening of 1 in the direction perpendicular to the central axis of the battery housing 1,
A battery housing 1a for housing each battery 5, and a battery housing 1a
Battery holder 4 that holds more than half of the battery circumference on top of the
And a partition wall 2 for partitioning each battery 5, the partition wall 2 is provided with a partition part 3 through which the + protruding electrode 15 of the battery 5 can penetrate, and the walls 2a at both ends of the battery housing 1 are + protruding electrodes. , -Provided with a notch (not shown) through which the coil spring of the device that abuts the electrode can penetrate. As shown in FIGS. 1 (a) and 2 (a), the thickness h2 of the partition wall 2 is about half the height h3 of the + protruding electrode 15 of the battery 5, and the length h1 of the battery housing portion 1a and the partition h1 The sum of the thickness h2 of the wall 2 corresponds to the total height of the battery (the height from the bottom surface 25 of the battery to the + top surface of the electrode 15) h (h = h1 + h2). I have decided h1.

With this structure, as shown in FIG. 2A, when each battery 5 is properly inserted into the battery housing 1, the + projecting electrode 15 penetrates the notch 3 of the partition wall 2, The adjacent batteries will be normally connected in series.

As shown in FIG. 1D, the battery storage portion 1a
Since the battery holding part 4 having a half circumference or more of the battery outer periphery is provided on the upper part of the battery, if the battery 5 is properly housed as shown in FIG. 2A, the battery housing is carried out as shown in FIG. 2B. Even if the opening of the portion 1a is in the downward position, the battery 5 does not easily come out of the battery housing 1 by its own weight. Therefore, the plurality of batteries 5 can be handled integrally.

As shown in FIG. 3 (a), when the battery 5c is erroneously inserted (when the negative electrodes 25 of the adjacent batteries are inserted in the opposite direction), the partition wall between the batteries 5c and 5b is inserted. Due to 2, the batteries 5c and 5b are not connected.

As shown in FIG. 3 (b), when the battery 5a is about to be erroneously inserted (when the + projecting electrodes of adjacent batteries are about to be inserted in the opposite direction), the battery 5a and the battery 5b are + Battery 5a with protruding electrodes 15a and 15b overlapping
Since it cannot be inserted into the battery storage portion 1a, an abnormality can be notified.

Further, the battery 5a can prevent the contact between the + protruding electrode 15a and the + protruding electrode 15b of the battery 5b before reaching the position P (the position of the battery 5a). Figure 4
In the above, since the battery 5 correctly inserted in the battery housing 1 can be handled as one unit, it can be operated to put one battery in the battery housing portion 6 of the portable electric lamp. Reference numeral 7a is a coil spring, which comes into contact with the negative electrode 25 of the battery 5 and is connected to the switch 9 via the lead 7b. 10 is a light bulb, and the tail terminal 10a
And the positive electrode 15 of the battery are in contact with each other. Light bulb 1 at this time
The tail terminal 10a of 0 is at a position deeper than the socket member 11, and when the battery 5 inserted in the battery housing 1 is housed in the opposite direction to the battery housing 6 of the portable electric lamp, the tail terminal of the light bulb 10 is stored. 10a and the negative electrode 25 of the battery 5 are not connected. Further, since the battery housing 1 is made of a sheet-shaped material, even if the opening of the battery holding portion 4 is narrower than the diameter of the battery 5, it is easily deformed when the battery 5 is taken in and out, so that the battery 5 can be taken in and out easily. it can. Moreover, since it is thin, it is not necessary to change the shape of the device significantly.

[0015]

As is apparent from the above description of the embodiments, according to the battery housing of the present invention, contact can be prevented when the battery is inserted in the reverse direction, and problems such as battery leakage can be obviated. To prevent. Furthermore, because it is made of sheet-shaped insulating material,
Even if a battery holding part that holds more than half of the outer circumference of the battery is provided, the battery can be easily taken in and out, and by providing this battery holding part, a plurality of batteries can be integrally held in the battery housing, and the tubular shape It can also be used for devices that have a battery storage part, and there is no need to change the shape of the device significantly. In addition, the sheet-shaped material can be processed by, for example, vacuum molding regardless of having a battery holding portion, and it is practically not required to use a complicated and expensive mold like injection molding. The effect is great.
