Patent ID: 7857658

Claim:
A connector for electrically coupling a PP3 battery with a battery-powered device, the connector comprising: a first dual-contact assembly including a positive contact configured to contact a positive PP3 terminal of the PP3 battery and a negative contact configured to contact a negative PP3 terminal of the PP3 battery; and a second dual-contact assembly including a positive contact configured to contact the positive PP3 terminal of the PP3 battery and a negative contact configured to contact the negative PP3 terminal of the PP3 battery, where each of the first dual-contact assembly and the second dual-contact assembly is configured such that when the dual-contact assembly is physically engaged with the positive PP3 terminal of the PP3 battery, the positive contact of the dual-contact assembly electrically engages the positive PP3 terminal while the negative contact is electrically insulated from the positive PP3 terminal, and where each of the first dual-contact assembly and the second dual-contact assembly is configured such that when the dual-contact assembly is physically engaged with the negative PP3 terminal of the PP3 battery, the negative contact of the dual-contact assembly electrically engages the negative PP3 terminal while the positive contact is electrically insulated from the negative PP3 terminal.
