Description of the Related Art A battery pack having a plurality of accumulators such as Ni-Cd batteries in a case made of a thermoplastic resin molded article is divided into two parts as disclosed in, for example, Japanese Utility Model Laid-Open No. 1-64851. There is a case in which the casings are pressurized and heated by ultrasonic waves, melted and solidified, and joined. This method
Compared to the case where screws are fixed between the cases, the structure is simple, small and rugged, and can be manufactured at low cost.

させてしまうといった危惧がある。[0003] Thus, there is a feature that the joining between cases by ultrasonic welding can be made strong. However, since ultrasonic vibration is generated at the time of welding, if ultrasonic welding is used for joining between cases of a battery pack containing a printed circuit board on which electronic components are mounted, the electronic component may be damaged by the ultrasonic vibration, or There is a concern that parts may be missing from the printed circuit board.

されて固定されている。On the other hand, Japanese Utility Model Laid-Open No. 59-33663 discloses a portable electronic device in which a battery section 3 and a printed circuit board 6 are housed in housings 1 and 2. The printed circuit board 6 of this device is inserted into a groove 9 provided in the housing 1. The battery unit 3 is pressed and fixed to the printed board 6 and the housing 2 by elasticity based on the bending of the printed board 6.

た危惧がある。However, this structure does not disclose any means for joining the casings 1 and 2. Therefore, it is unclear whether the joining is performed by ultrasonic welding. Here, a case where ultrasonic welding is used for this structure will be considered. Since the battery section 3 is pressed by the printed circuit board 6 and the housing 2 and the printed circuit board 6 is inserted into the groove 9 while being bent, the printed circuit board 6 exerts a strong force on the housings 1 and 2. , So that the ultrasonic vibration is very easily transmitted. For this reason, even in this case, there is a fear that the electronic component may be damaged or may be dropped from the printed circuit board.

In this case, an elastic member 8 such as urethane is inserted. At this time, since the elastic member 8 absorbs the ultrasonic vibration, the material of the support 6 is not limited. FIG. 4 shows that the elastic member 8 is inserted between the printed circuit board 4 and the Ni-Cd battery 3, while the protrusion 7 is formed on the entire periphery of the support 6 in the direction of the second case 2. It is.
