Abstract
A housing contains electrical components that constitute a battery-operated smoke detector and alarm. Forming a part of the housing is a transverse wall that includes at least one opening. Adjacent to that one opening in one surface of the wall are a first succession of semi-cylindrical cavities each diametrically sized to seat a cylindrical battery. A support web is suspended from the wall in a position spaced from and opposite the opening with the wall-facing surface of that web including a second succession of semi-cylindrical cavities each diametrically sized to seat the battery and aligned with the respective cavity formed on the wall so as to captivate a battery therebetween. A cover member is matable with the wall so as to overlie the compartment in which the batteries reside. A lug depends from the cover for locking reception with an aperture formed in the transverse wall. An ear depends from the cover in a position to press against the battery when the cover is installed. Desirably, there are a space-opposed pair of such apertures, lugs and ears, together with a slot positioned in the wall in relationship to the battery opening so as to receive either of the ears when the lugs are engaged in the apertures. The wall also has an inwardly struck wall portion and inwardly projecting posts that serve to mount an electrical-component-mounting substrate.
