Abstract
A system of cordless power tools includes a cordless power tool adapted to removably receive a rechargeable battery pack. The system further includes a battery pack charger and a converter for converting AC electricity to DC electricity. A battery pack interface block is captured between clam shell halves of a battery pack housing and includes a plurality of male blade terminals. The male blade terminals are received within recessed female terminals of a tool terminal block and similarly received by recessed female terminals of the charger. The tool terminal block further includes a pair of male terminals which engage recessed female terminals of the converter. Apertures are provided in guide rails of the battery pack to receive the male terminals of the tool terminal block.
