ABSTRACT:
A unique housing (104 and 600) of a portable radio transceiver (100) is described that takes advantage of the heat sinking, electrical shielding and structural characteristics of a battery. The unique electronic circuitry housing (104 and 600) includes a battery as a structural element thereof. In one illustrated housing (104), a stick battery (210) is attached to the side of a transmitter printed circuit panel (213). A logic printed circuit panel (212) and a receiver printed circuit panel (214) are positioned above and below the transmitter printed circuit panel (213), respectively, and are held together by interlocking side rails (206,207). In a second illustrated housing (600), a flat battery (602) is attached to the sides of a first U-shaped printed circuit panel (604). A second U-shaped printed circuit panel (606) is positioned between the battery and the first panel (604). Heat dissipated by the electrical components on the second panel (606) is conducted away by the flat battery (602). The electronic circuitry housing of the present invention may be advantageously utilized in a variety of applications where electronic circuitry is operated from a battery.
