Battery pack
First Claim
1. A battery pack comprising:
- a housing including an inner cavity, an interface for receiving a power tool, and drain holes on a base portion of the housing;
battery cells positioned within the cavity;
a first latch member extending through the housing;
a second latch member extending through the housing, the first and second latch members operable to secure the battery pack to the power tool;
electrical terminals electrically coupled to the battery cells and operable to interface with the power tool;
a latch cover within the inner cavity of the housing supporting the first and second latch members, wherein the latch cover is within the housing such that the housing covers the latch cover; and
a first water discharge pathway extending along the latch cover, downward along a first space between the battery cells and the housing, to the drain holes;
wherein the first water discharge pathway directs water infiltrating the battery pack to the drain holes.

Abstract
The present invention relates to a battery pack including a housing, a latch mechanism, a printed circuit board connected to electrical terminals, and an internal frame. The housing includes a first and second portion. The first portion includes openings that receive the latch mechanism and openings that receive the terminals. The battery pack also includes a latch cover that protects against water infiltrating between the openings and the latch mechanism, and a terminal cover that protects against water infiltrating between the first housing portion and the terminals. Water that enters the battery pack is directed to the bottom of the battery pack. The water is then drained through openings in the lower housing portion. The internal frame includes openings that secure batteries within the lower housing portion with the help of wedges that are positioned in between adjacent rows of batteries.
