Abstract: A battery pack may include a fusible link plate having a bent shape. The fusible link plate may include: a first plate part extending in a first direction; a second plate part extending in a second direction; and a bent part connecting the first plate part to the second plate part. The first plate part, the second plate part, and the bent part may be disposed along a first plane that is along both the first direction and the second direction. The first plate part may include a portion having a first cross-sectional area. The second plate part may include a portion having a second cross-sectional area. The bent part may include a first fusible part having a third cross-sectional area. The third cross-sectional area may be smaller than the first cross-sectional area and smaller than the second cross-sectional area.

Abstract: An electrical device may be provided with: a housing to which a battery pack is attached detachably by sliding the battery pack in a sliding direction; a battery connection terminal configured to be electrically connected to the battery pack attached to the housing; and a terminal cover configured to move between a protection position for protecting the battery connection terminal and an exposure position for exposing the battery connection terminal. The housing may include a cover rail extending along the sliding direction. The terminal cover may include: a cover body having a shape that at least partially covers the battery connection terminal; and a hook formed integrally with the cover body, and the hook is engaged with the cover rail so as to slide in the sliding direction.
