    摘要: A battery pack may include a positive pack terminal, a negative pack terminal, a cell assembly, a busbar strap, and an electrical pathway. The cell assembly includes battery cells. The busbar strap has a current collection tab and a battery connection plate. The battery connection plate is electrically connected to the battery cell closest to the current collection tab. The electrical pathway extends between the current collection tab and the battery connection plate. The electrical pathway includes a first path portion that extends between the current collection tab and an area past the battery connection plate and a second path portion that extends between the area past the battery connection plate and the battery connection plate.

    摘要: A protective cap including an outer shell and an impact absorbing liner are constructed of materials designed to provide impact protection to a wearer. In some embodiments, the outer shell includes an outer surface pattern and/or an inner surface pattern to provide better grip and reduce rotation between the outer shell and the impact absorbing liner and/or the outer shell and a hat the user wears to cover the protective cap.

    摘要: A printed circuit board assembly for use in a power tool includes a potting boat, a printed circuit board, a thermally conductive gap pad, potting material, and a secondary heat sink. The potting boat includes primary heat sink fins. The electronic components are mounted on a first surface of the printed circuit board. The gap pad contacts the electronic component and the stand-off. The potting material at least partially encapsulates the printed circuit board within the potting boat. The secondary heat sink contacts a second surface of the printed circuit board opposite the first surface. The secondary heat sink includes secondary heat sink fins. Heat generated by the electronic components is transferred via conduction to both the primary heat sink fins and the secondary heat sink fins. The heat is dissipated to the surroundings of the printed circuit board assembly.
