Abstract

PROBLEM TO BE SOLVED: To constitute a structure for batteries housed in a box-type cover so as not to swing by some external force by holing internal batteries without fail and excluding inner clearance. SOLUTION: This construction is composed of a cover with a structure housing a battery that can supply electric power to an electronic unit proper and mechanically be mounted thereon, an elastic member that is provided on an opposite wall facing this cover and presses the periphery of the battery at a desired interval, and another cover with a structure of fitting the cover.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case for accommodating, for example, an alkaline or lithium battery of a secondary battery employed in an electronic apparatus body, and more particularly to a battery case in which a battery is securely held inside. It is related to the internal structure of.

[0002]

2. Description of the Related Art A recent electronic device, for example, a portable electronic device, employs a lithium battery which has been used for a long time, and a circuit for protecting the lithium battery is connected to the lithium battery to make the device very small. For example, plastic or the like is housed in a battery case molded into a box shape. The battery case has an upper lid and a lower lid so that the internal battery can be replaced as needed.

[0003] However, when the stored battery is shaken by some external force in the case, there is a concern that the electrode portion of the battery becomes difficult to conduct over time, and there is also a fear that the lead wire or the like may come off due to external force. In particular, a structure in which the battery does not shake due to some external force in the battery case is required.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a power supply to an electronic device main body and a lid configured to receive a battery in a structure capable of being mechanically attached, An elastic member provided on the opposing wall of the lid and pressing the periphery of the battery at a desired interval, and the other lid covered by the one lid and the fitting structure ensure the internal battery. The structure is such that the gap is held and the internal space is eliminated, so that the battery is not shaken by any external force in the box-shaped lid.

[0005]

Means for Solving the Problems The means of the present invention for solving the above-mentioned problems has a structure in which a battery is housed in a structure in which power can be supplied to the main body of the electronic equipment and can be mechanically attached. It comprises one lid, an elastic member provided on an opposing wall of the lid and pressing the periphery of the battery at a desired interval, and the other lid closed by a fitting structure with the one lid. .

[0006]

By arranging the elastic member on the opposing wall, a part of the peripheral surface of the battery is elastically pressed, so that the battery is kept in the battery case body without being shaken by any external force. There is no concern about incomplete contact of the contact portion.

[0007]

FIG. 1 shows an embodiment of the present invention, in which a battery pack main body 1 is developed to show an upper lid 2 and a lower lid 3. FIG. 2 is a top view showing a state where the battery 4 is stored. The lower cover 3 is formed in a box shape and has a structure in which the upper cover 2 can be covered with an intaglio fitting structure from above. An elastic member 5 is provided on the opposite side wall of the lower lid 3 in this case.
It is located in several places. The interval is set such that the arc on the peripheral surface of the battery 4 can be sufficiently contacted and pressed. FIG. 2 shows an example in which two batteries 4 are stored, and the batteries 4 are elastically pressed by the elastic members 5 so that the batteries 4 do not swing without any external force without the battery pack body 1. Therefore, there is no fear that the electrical connection portion such as the electrode connection portion becomes unstable.

[0008]

As described above, according to the present invention, one of the lids has a structure in which the battery is housed inside the electronic device main body, which is configured to be capable of supplying power to the electronic device main body and being mechanically attachable.
An elastic member provided on the opposing wall of the lid and pressing the periphery of the battery at a desired interval, and the other lid covered with the one lid and the fitting structure, so that the internal battery has some sort of This eliminates the concern that the contact state of the electrical contact portion becomes unstable due to the swing due to the external force.
