ABSTRACT:
An improved housing assembly for housing miniaturized electrical or electronic apparatus, such as a radio receiver or monitor, is disclosed wherein a single piece housing is provided, open at the top for receiving an associated electrical chassis with self-contained battery compartment and a sound transducer. A control panel attached to the electrical chassis cooperates to overfit the open end of said housing to complete the overall assembly. The assemblage of the housing apparatus requires no screws, fasteners or special tools as the respective component parts effect a snap-fit with one another. A novel interlocking arrangement between chassis assembly and housing disguises the latching interfit therebetween, which nevertheless may be released by the insertion of a simple blade tool at the proper location. Complete shock mounting and protection from dust and dirt is effected by resilient gasket elements in cooperation with the housing and chassis assembly. A transparent lens cover is incorporated on a portion of the bottom panel to overlie an information placard referencing operational data but which, in addition, includes features which show if unauthorized access has been effected to the internal chassis assembly.
