Abstract

PROBLEM TO BE SOLVED: To provide a structure of lids of a battery case, in which upper and lower lids can be smoothly joined together with preventing the two lids from facing the opposite direction also with preventing the two lids from being turned upside down owing to a concave area and a convex area respectively formed at open edges of the two lids when taking a side view of the two lids, wherein the lids are asymmetrically shaped in a horizontal direction. SOLUTION: In a structure of a body of a battery case which stores a chargeable battery inside thereof for supplying electric power of the battery to a body of electronic apparatus and comprises an upper and lower lids which can be structurally attached to or detached from the body of electronic apparatus, a structure of the upper and lower lids is characterized in that a concave area and a convex area are respectively formed at open edges of the upper and lower lids when taking a side view of the two lids, therefore, the upper and lower lids are joined together owing to the shapes of the concave part and the convex part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of upper and lower lids of a battery case for accommodating an alkaline or lithium battery of a secondary battery used in, for example, portable electronic equipment.

[0002]

2. Description of the Related Art Lithium batteries, which have been used for a long time, have been used in recent electronic devices, for example, portable electronic devices. It is housed in a battery case body, and furthermore, a protection circuit is housed in this case, so that power is supplied to the body of the electronic device. Such a battery case main body is composed of an upper lid and a lower lid, and usually, the openings of both lids are configured to have an intaglio fitting structure and are covered.

[0003] However, since the battery case body is rectangular, a mark or the like indicating the top and bottom is displayed on the surface of the upper lid so as not to be turned upside down. In this way, the upper and lower parts are not turned upside down during assembly, but when assembling, look at this mark and check the lid, but if the lower side is upside down the lid may be forcibly inserted. Damaged joints may result in defective parts or lack of smoothness on the assembly.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to cover an upper cover and a lower cover of a battery case main body.
Provide the concave and convex parts when viewed from the side at the opening edges of both lids so that the lids can not be made if they are reversed. It is intended to provide a battery case lid structure capable of smoothly closing the lid.

[0005]

The present invention for solving the above-mentioned problems contains a rechargeable battery therein, supplies the power of the battery to the electronic device main body, and attaches and detaches the battery to and from the electronic device main body. In the structure of the battery case main body including the upper lid and the lower lid having a structure that can be formed, a concave portion and a convex portion are provided on the opening edges of the upper lid and the lower lid as viewed from the side, and are combined in the shape of the uneven portion. is there.

[0006]

The above-mentioned battery case body has concave and convex portions as viewed from the side at the opening edges of the upper lid and the lower lid, and the upper and lower lids are fitted by using this portion as a guide. Because it is not possible, it can be easily realized structurally without forcibly covering.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings and FIG.

Reference numeral 1 denotes a battery case main body. The battery case main body 1 is a box made of a synthetic resin having a bottom and formed in a substantially rectangular shape. In the center of the battery case 1, for example, a lithium battery or the like as a secondary battery is placed. Usually, a compensation circuit is connected to this battery. The battery case main body 1 is composed of an upper lid 2 and a lower lid 3, and the peripheral edges of the respective openings are substantially combined with each other by fitting a seal.

Next, an opening edge 4 of the upper lid 2 and the lower lid 3
Are provided with a concave portion 5 and a convex portion 6 when viewed from the side. That is,
The upper lid 2 is formed by forming a concave portion 5 at the opening edge and forming a convex portion 6 at a corresponding position of the lower lid 3 covered by the concave portion. Things. When upper lid 2 and lower lid 3 are opposite, concave section 5 and convex section 6
Since it is not combined with the above, the lid cannot be formed and the operation of forcibly closing the lid cannot be performed.

When the concave portion 5 and the convex portion 6 of the above embodiment are combined in various shapes, the reverse combination can be prevented. In other words, by making the upper lid 2 and the lower lid 3 asymmetrical in the vertical direction, not only the left and right sides of the lid can be confirmed with the fingertips, but also the slip can be prevented.

[0011]

As described above, according to the present invention, a rechargeable battery is housed therein, the power of the battery is supplied to the electronic device main body, and the upper and lower lids are structured to be detachable from the electronic device main body. In the structure of the battery case main body comprising: a concave portion and a convex portion as viewed from the side at the opening edges of the upper lid and the lower lid, the upper lid and the lower lid are inverted, and the lid is inverted. As a result, there is an effect that no defective parts are generated and the assembly is smooth.
