けることが望ましい。(c) Problems to be solved by the invention In the device disclosed in Japanese Patent Publication No. 56-9789, the connection terminal is provided only on the end face of the battery pack body. However, when considering the versatility of the battery pack, it is desirable to provide the terminal fittings from the end face to the side face of the case.
これを解決するものとして、第７図に示す電池
パツクPcがある。しかし、電池パツクPcでは、
端子金具７ｃが電池５ｃの側部に接触することが
あり、その側部が異極である場合には短絡が起き

超音波溶着が多く用いられている。 In addition, battery packs used in small electrical devices are
Volumetric space must be minimized. Therefore, it is desirable that the shape be arched along the group of batteries to be accommodated. In addition, as a case to store the battery group,
It is common to have a pair of half-split cases with substantially the same shape, and ultrasonic welding is often used to join the pair of rectangular cases.

が発生する。 Now, in the structure disclosed in Japanese Patent Application Laid-open No. 164226/1983, the joining structure of two halves of substantially the same shape causes problems in adhesion by ultrasonic welding. In other words, in the case of ultrasonic welding, in which the joint surface of the case generates frictional heat due to longitudinal vibration (perpendicular to the joint surface) and welds, the mounting surface and bottom surface of the terminal fitting, which are flat vertical surfaces, The conduction of ultrasonic vibrations to the joint surfaces of each arch-shaped side part is different, and arch-shaped side parts are difficult to weld because vibrations are attenuated. Therefore, if welding conditions are set based on this side surface, it will be necessary to apply considerably large ultrasonic vibrations, and the easily welded vertical flat terminal mounting surface and bottom surface will be eluted onto the outer surface of the case. A problem arises in that the value of the product is lost in terms of size and appearance.
