In a grinder, a terminal plate is projectingly provided on an upper surface of a controller. A connection portion, which accommodates a female terminal and includes a slit into which the terminal plate enters, is projectingly provided on a lower surface of a main body portion of a switch block. At the time of assembling of the switch block and the controller, the terminal plate that enters into the connection portion from the slit is inserted into and connected to the female terminal. First and second projections that cover a formation surface of the slit in the connection portion when the connection portion is inserted with and connected to the terminal plate are formed on the upper surface of the controller.

An adapter for a power tool powered by a detachable battery pack includes a connector for directly connecting the adapter only to the power tool in a detachable manner, a controller, at least one memory and/or storage device in communication with the controller, and at least one communication port configured to transmit electrical communications from the adapter controller to a controller located in the power tool and vice versa. The adapter is further configured such that, when a battery pack, which also includes a controller, is connected to the power tool, a communication path is established from the battery pack controller to the adapter controller via the power tool controller.

A power tool system includes a hand-held power tool having a motor or a solenoid that drives a tool, and a first memory that stores at least one pass code. A battery pack is detachably attached to, and supplies current to, the power tool and has a second memory that stores at least one pass code. An electronically-actuatable lock and a first controller are provided in the power tool and/or in the battery pack. The first controller reads the pass codes from the first and second memories when the battery pack is attached to the power tool, directly compares the pass codes from the first memory and the second memory, and causes the first electronically-actuatable lock to prohibit or impair operation of the power tool when the pass codes do not match or otherwise correspond in a predetermined manner.
摘要:
A method for recharging a battery pack includes attaching a portable charger to a user, which portable charger includes or is attached to a self-contained power supply and wherein a first charging port of the portable charger is disposed, e.g., on a belt worn by the user, hanging the battery pack on the belt while the battery pack is physically engaged and in electrical communication with a power tool, and initiating a transfer of power from the charger to the battery pack when the first charging port is at least proximal to a second charging port that is in electrical communication with at least one battery cell of the battery pack. A portable charging system capable of performing this method, as well as an adapter for use in performing this method, are also disclosed.
