BATTERY PACK AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/113644
Kind Code:
A1
Abstract:
The present invention provides a battery pack and an electrical device which are configured so that the position of a battery-side terminal portion does not shift even when a case is subject to impact resulting from falling and the like. A battery pack 1 has an upper case 10 and a lower case 2 sandwiching therebetween a separator 50 holding a battery while a circuit board 70 having the battery-side terminal portion is fixed to the separator 50. Hooks 61, 62 are provided in parts of the separator 50 which face the upper case 10, and the upper case is provided with recessed portions 29a, 29b which engage with the hooks 61, 62, respectively. When the upper case 10 and the lower case 2 are screwed together, the hooks 61, 62 enter the recessed portions 29a, 29b to achieve a fitted state. Accordingly, even when the lower case 2 is subsequently detached, the separator 50 maintains the state of being held on the upper case 10 side.
