Abstract
A portable radiotelephone device (100) comprises a radio housing (114) having radiotelephone circuitry (1102), a battery housing (110) having a battery (1104) and an accessory housing (1100) having accessory circuitry (1106). A first latch mechanism (116) secures the battery housing (1100) to the radio housing (114) to permit the battery (1104) to power the radiotelephone circuitry (1102) via a first pair of conductive power contacts (1108, 1110). A second latch mechanism (118) secures the accessory housing (1100) to the battery housing (110) to permit the battery (1104) to power the accessory circuitry (1106) via a second pair of conductive power contacts (112, 1112). Alternatively, a first pair of conductive data signal contacts (1116, 1118) between the radio housing (114) and the battery housing (110) and a second pair of conductive data signal contacts (1120, 1122) between the battery housing (110) and the accessory housing (1100) permit data signals to be passed between the radiotelephone circuitry (1102) and the accessory circuitry (1106). Alternatively, a mechanical device (812) having no electrical function is interchangeable with the accessory housing (1100) to be releasably secured to the battery housing (110).
