Description

  The present invention relates to a battery pack, and more particularly to a dimension correction structure for a so-called built-in battery pack built in an electronic device.

Recently, mobile phone devices are rapidly becoming widespread because they are small and light, and can be communicated in most areas even while moving, and are very convenient. In such mobile phone devices, secondary batteries whose continuous use time has become longer due to technological progress are packed together with a protection circuit and are widely used as battery packs. The battery pack is classified into a built-in type built in the electronic device main body and a so-called external type that forms an external appearance integrally with the external appearance of the electronic device main body. In either case, a structure is employed in which the reliability of electrical coupling to the electronic circuit of the electronic device body and the reliability of structural coupling can be measured. However, since the built-in battery pack is electrically coupled to the electrodes of the electronic circuit in the electronic device body, it is necessary to prevent the mutual electrodes from being opened by some impact. In other words, when a so-called instantaneous interruption occurs in which the electrode of the electronic circuit of the electronic device and the electrode of the battery pack are released momentarily, the power of the battery pack is not supplied to the electronic circuit of the electronic device body, and the electronic circuit is adversely affected. Become.

Embodiment 1 of the present invention will be described below with reference to the accompanying drawings, FIG. 1, FIG. 2, and FIG.
Reference numeral 1 in FIG. 1 denotes a lower lid of a battery pack made of resin such as plastic, and forms an upper lid 2 to be fitted. A battery 3 having a flat rectangular shape and having a charging function is accommodated in the lids 1 and 2. The battery 3 has an electrode 4, and the electrode 4 is provided on one surface of the battery pack body 5 including the upper lid 2 and the lower lid 1 so as to be exposed to the outside.

  The electrode 4 is a flat electrode, and this electrode is electrically connected to the electrode of the battery 3. In addition, a pin electrode 6 electrically connected to the electronic circuit of the electronic device main body is elastically pushed from the back and is in contact with the electrode 4. Therefore, the tip of the pin electrode 6 has a structure in which the tip of the pin electrode 6 is in contact with the electrode 4 and is electrically conductive.

  FIG. 3 is an enlarged view of this portion. Since such a pin electrode 6 may be separated from the electrode 4 by some vibration, an arc-shaped dimension correcting body 7 made of the same material as the battery pack body 5 is integrally formed on the side surface of the lower lid 1 of the battery pack body 5 in the previous period.
