Abstract:
A system of cordless power tools, comprising:a battery pack having a battery pack terminal block, a battery and a housing, the battery pack terminal block having a plurality of first terminals that are electrically coupled to the battery, each of the first terminals being associated with a terminal insertion plane, each of the terminal insertion planes being spaced apart from one another in a lateral direction, the housing defining a pair of spaced apart guide rails, a floor and a cavity into which the battery and the battery pack terminal block are disposed, the guide rails defining an insertion axis, the battery pack terminal block being arranged relative to the guide rails such that each of the terminal insertion planes is generally parallel the insertion axis and perpendicular to the floor, the floor being disposed below the first terminals; and a power tool having a tool terminal block, an electric motor and a tool housing, the tool terminal block having a plurality of second terminals that are electrically associated with the electric motor, the tool housing defining a battery pack mounting aperture and a pair of grooves, the battery pack mounting aperture being configured to receive at least a portion of the battery pack, each of the grooves being configured to receive an associated one of the guide rails when the battery pack is slidingly inserted to the tool housing along the insertion axis; wherein the guide rails and the grooves cooperate to grossly align each of the second terminals to a corresponding first second terminal and wherein each of the second terminals engages the corresponding one of the first terminals when the battery pack is fully inserted into the tool housing.
