The battery operated handheld power tool is characterized in that the body portion () comprises a fan (), arranged to generate a flow of air passing by the control unit () during operation of the power tool ().

Battery operated handheld power tool

A battery operated handheld power tool, comprising a working tool assembly (), a handle assembly () and an elongate tubular rod (). The working tool assembly () comprises a motor housing () having a first inner space (), comprising an electric motor () with a fan (). The first inner space () is connected to the exterior of the working tool assembly () by means of at least one air outlet (). The handle assembly () comprises a second inner space () in which a control unit () is positioned, the second inner space () being in flow communication with the exterior of the handle assembly (). The elongate tubular rod () defines an air guiding channel (), in flow communication with the first inner space () and the second inner space ().

A battery pack for powering a battery powered tool may include a housing, a plurality of cells and an electrical connection assembly. The housing may include a sidewall assembly configured to correspond to respective sidewalls of a battery compartment defined at a portion of the battery powered tool to facilitate insertion of the battery pack into the battery compartment. The sidewall assembly may form an enclosure around the plurality of cells on all sides substantially parallel to the direction of insertion. The electrical connection assembly may be disposed at a portion of the sidewall assembly to communicate the combined output to a connector disposed at a corresponding sidewall of the battery compartment. The electrical connection assembly may be arranged to engage the connector responsive to movement of the battery pack in a direction substantially parallel to the direction of insertion of the battery pack into the battery compartment.
