摘要:
A PDA (10) and an external battery pack (100) for fitting thereto. The battery pack (100) can be used to supplement an internal battery of the PDA (10). The PDA (10) has electrical contacts (40) that are for contacting electrical contacts (140) of the battery pack (100). The electrical contacts (40) of the PDA (10) are heat staked into material of a casing (20) of the PDA (10) to provide sealing therebetween. Electrical contact between the contacts (40) of the PDA (10) and a PCB (50) contained therein is provided by a respective helical spring (46) that abuts each contact (40) and the PCB (50). This helps to maintain the contact in the event that the PDA (10) is dropped. The electrical contacts (140) of the battery pack (100) are insert moulded in casing thereof to provide sealing therebetween.
