Abstract: A phone housing includes an attachment section for receiving a battery pack. A slot in the phone housing receives a latch made formed from a unitary piece of plastic. The latch inserts and locks inside the slot and is compressible inside the slot allowing the battery pack to be inserted into the attachment section. After the battery pack is seated in the attachment section, the latch springingly expands out of the slot engaging with the battery pack. The latch includes a unique combination of legs that operate as a spring and arms that serve to lock the latch inside the slot.

Abstract: An antenna clip includes a U-shaped front end that slides into a slot on an edge of a printed circuit board (PCB). The PCB holds the clip rigidly in both a lateral direction and in a front to back parallel orientation with the PCB providing a reliable electrical contact between the antenna and the phone electrical circuitry. An antenna switching circuit switches between an internally connected antenna and an external system detachably coupled to an external connector. The antenna circuit has a wire length of .lambda./4 between the phone circuit and the antenna and a wire length of N.lambda./2 between the phone circuitry and the external system. The antenna then appears as an open circuit when coupled to ground through a diode. Alternatively, the external connector appears as an open circuit when disconnected from the external system.
