ABSTRACT:
A connector is provided for electrically coupling a battery with a battery-powered device. The connector includes a first dual-contact assembly and a second dual-contact assembly. Each of the dual-contact assemblies includes a positive contact for contacting a positive PP3 terminal of a PP3 battery, and a negative contact for contacting a negative PP3 terminal of the PP3 battery. Each dual-contact assembly is configured so that, when the dual-contact assembly is physically engaged with either of the PP3 battery terminals, one of the contacts of the dual-contact assembly electrically engages the PP3 battery terminal, while the other of the contacts of the dual-contact assembly is electrically insulated from the PP3 battery terminal. Accordingly, the PP3 battery may be installed in either of two valid connection states relative to the connector, in which appropriate electrical connectivity is provided via the connector to a device to be powered by the PP3 battery.
