Abstract: A power tool is provided including a battery receptacle disposed at a foot of a handle portion, and an integrated power module disposed at or proximate the foot of the handle portion. The integrated power module includes: a module housing having a base body and a terminal support body extending substantially perpendicularly and integrally from an end of the base body in a downward direction; a circuit board mounted within the module housing over the base body and including an inverter circuit electrically coupled to the motor; a battery terminal block supported by the terminal support body to make a connection with a removable battery pack; and conductive connectors extending from the battery terminal, through the terminal support body and the base body of the module housing, to the circuit board, to supply power from the battery pack to the inverter circuit.

Abstract: A power tool includes a housing including a motor case and a handle; a motor disposed within the motor case and having motor lead wires; a battery receiving portion provided on an end of the handle configured to receive a removable battery pack; a control unit configured to receive electric power form the battery pack and output power wires; and a wire guide and retention unit disposed within the handle. The wire guide and retention unit includes a main body and ring terminals fastened to the main body. The ring terminals couple with the motor lead wires on one end and with the power wires on another end.
