Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case body for accommodating a secondary battery in a battery case body attached to a portable electronic device such as a portable telephone for carrying out wireless communication. The present invention relates to an improvement in a structure for assembling a battery case.

[0002]

2. Description of the Related Art In recent years, portable electronic devices, for example, mobile phones have been desired by users as a whole to be thin, lightweight, and compact, and these tendencies have been further strengthened. As shown in FIG. 1, such a portable electronic device employs a battery cover 2 containing a battery 1 of a charge type (for example, a lithium secondary battery). The battery cover 2 is used together with a circuit for controlling the lithium battery. It is configured to be built in the battery case main body 3. The battery case body 3 is mechanically and electrically housed in a place where the battery case body 3 of the portable electronic device is housed, and supplies power.

That is, when the conventional battery cover 2 is housed in the battery case main body, as shown in FIG.
A bent plate 4 is provided integrally at a diagonal corner inside the battery case body 3 and disposed integrally with the battery case body 3, and a battery cover 2 containing a battery inside from above is formed by the bent plate 4 at the corner. It is structured to be inserted and arranged so as to be sandwiched.

In this structure, the plate 4 has only the requirement of sandwiching the battery cover 2. Therefore, when the battery cover 2, which is relatively not marked on the surface, is placed in the battery case main body 3, the front and rear sides of the battery cover 2 are relatively short. On the contrary, this is not found and cannot be rejected structurally, so that it is easily stored, so that many errors in the assembly work occur. This can be similarly applied to a conventional device in which the contact plate 4 is not used.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a battery cover having a substantially rectangular shape in which a substantially rectangular secondary battery is accommodated and having one shorter side shorter than the other short side. And a battery case main body that can be electrically and mechanically attached to a portable electronic device such as a mobile phone that carries and wirelessly communicates with the mobile phone, so that the battery cover is turned upside down and is not stored in the battery case main body. The present invention provides a battery case assembly structure that can reliably eliminate assembly errors.

[0006]

Means for Solving the Problems A means for solving the problem of the present invention is a battery cover having a substantially rectangular shape containing a secondary battery and having one shorter side shorter than the other shorter side. It comprises a battery case body that can tightly house the battery cover and can be electrically and mechanically attached to a portable electronic device such as a mobile phone that carries and wirelessly communicates.

[0007]

[Function] When the battery cover is stored and assembled in the battery case body, if the battery is to be stored upside down, the storage side is similar because the storage side is similar. is there. That is, it is not stored upside down.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. FIG. 2 is a schematic assembly view in which the battery cover 10 is developed with respect to the battery case main body 12. Reference numeral 10 denotes a substantially rectangular flat battery 11 which can be charged inside (for example, a lit-matter battery is indicated by a dotted line).
Is a plastic battery cover that tightly accommodates the battery.
The outer shape of the battery cover 10 is substantially rectangular, and one of the short sides of the rectangle is set to be longer than the other short side.

Reference numeral 12 denotes a battery case body made of plastic. A portion of the battery case body 12 for housing the battery cover 10 has a shape similar to the outer shape of the battery cover 10 and is slightly larger in size. Dimensions are adjusted so that can be stored tightly. In other words, in the appearance of the battery case body 12, the dimensions of the opposing sides are set to be the same, and the dimensions of the internal storage locations are different on the opposing short sides.

Although not shown, the battery case main body 12 has a structure which can be electrically and mechanically attached to a portable electronic device such as a portable telephone for wireless communication.
The power of the internal battery can be supplied to the portable electronic device. Thus, the battery cover 10 does not need to be turned upside down and assembled to the battery case body 12.

A battery cover 10 is attached to the battery case body 12.
When storing the battery cover 10, the short side of the battery cover 10 may be stored so as to match the short side in the storage of the battery case main body 12. The long side of the battery cover 10 corresponds to the side and cannot be stored in the battery case body 12. If they are forcibly stored, they cannot be stored because the dimensions are different, and after all, they are not stored upside down. Incidentally, one of the long sides may be shortened.

[0012]

As described above, according to the present invention, a battery cover having a substantially rectangular shape containing a secondary battery and having one shorter side shorter than the other shorter side is provided. It consists of a battery case body that can be stowed and is electrically and mechanically attachable to a portable electronic device such as a mobile phone that carries and wirelessly communicates. , And the battery cover can always be stored in the battery case body in a normal storage state.
