Cordless power tool system

A battery pack for a cordless power tool, the battery pack comprising:

• a housing having first and second halves defining first and second chambers;
• a battery disposed in said first chamber;
• and
• a terminal block electrically connected to said battery, said terminal block disposed in said second chamber and captured between said first and second halves.

A battery pack for a cordless power tool comprising:

• a battery pack housing including first and second laterally spaced sides and a rear side oriented substantially perpendicular to said first and second laterally spaced sides;
• and
• first and second protrusions disposed adjacent said rear side on said first and second laterally spaced sides, respectively, both of said first and second protrusions being generally convexly curved;
• whereby said protrusions facilitate manual extraction of the battery pack from the cordless power tool.

A method of releasably and electrically interconnecting a battery pack with a tool terminal block of a cordless power tool, the cordless power tool having a housing defining a pair of tool grooves, the tool terminal block including a pair of female terminals and a pair of laterally spaced terminal block guide rails, the method comprising the steps of:

• providing a rechargeable battery pack including a pair of laterally spaced apart battery pack guide rails and a pair of battery pack grooves subjacent to said battery pack guide rails, said battery pack further including a battery pack terminal block for interfacing with said tool terminal block, said battery pack terminal block including a pair of blade terminals;
• grossly aligning said tool terminal block and said battery pack terminal block by engaging said battery pack guide rails and tool grooves in a generally loose fit and subsequently sliding said battery pack guide rails relative to said tool grooves a first distance;
• and
• precisely aligning said battery pack relative to said tool terminal block by sliding said guide rails relative to said grooves a second, additional predetermined distance such that said terminal block guide rails engage said pair of battery pack grooves in a generally tight fit.
