CHARGER, BATTERY PACK CHARGING SYSTEM AND CORDLESS POWER TOOL SYSTEM

摘要

A charger (40; 240; 340) charges a battery pack (20) that is detachably attachable to a cordless power tool (12). The charger has at least a first side wall (44b) that at least partially defines a battery pack receiving hole (44; 244) shaped to receive and accommodate the battery pack. A charging output element (62; 362) supplies charging power to the battery pack. The battery pack receiving hole has a lateral cross sectional area that decreases downwardly in the vertical direction of the battery pack receiving hole such that gravity causes the battery pack to be guided to a prescribed position within the battery pack receiving hole. In addition, the charging output element is positioned so as to be proximal to a corresponding charging power input element of the battery pack when the battery pack is disposed in the prescribed position.
