摘要:
A system of cordless power tools includes a cordless power tool adapted to removably receive a rechargeable battery pack. The battery pack and the power tool can have complementary grooves and rails or L-shaped surfaces that aid in aligning the positive and negative blade terminals of the battery pack to the positive and negative tool terminals, respectively, of the power tool.

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.

A system of cordless power tools includes a cordless power tool adapted to removably receive a rechargeable battery pack. In each embodiment, the battery pack and the power tool have complementary rails and grooves that aid in aligning the positive and negative blade terminals of the battery pack to the positive and negative tool terminals, respectively, of the power tool. In one embodiment, a keying feature cooperates with a mating keying feature to further align the terminals of the battery pack to the terminals of the power tool. In a second embodiment, the battery pack includes two sets of blade terminals, with each set including a positive blade terminal and a negative blade terminal.

摘要:
A cordless system has cordless system components that include a cordless device, such as a cordless power tool, a battery pack and a charger. The battery pack is mated with either the cordless device to provide power to operate the cordless device or to the charger to charge the battery cells in the battery pack. In an aspect of the invention, the cordless system has an identification and communication system by which the battery pack identifies and communicates information about the battery pack to the cordless device or to the charger to which the battery pack is mated. In another aspect of the invention, the battery pack of the cordless system is capable of multiple modes, such as controlling the cordless device and controlling the charger. In yet another aspect of the invention, the battery pack validates the cordless device or charger to which it is mated. In still another aspect of the invention, the cordless system uses any of a wired interface, radio frequency interface, an optical interface or a magnetic interface to communicate information between the battery pack and the cordless device or charger to which the battery pack is mated.
