Abstract
A portable tool for mobile use includes a housing, an electric motor located in the housing, an insert shaft on the tool, and a battery. The battery or a terminal for connecting to an external energy source is located in the insert shaft. A mechanically or hydraulically driven movable piston rod is for performing spreading, cutting, lifting, and/or pressing. An electronic device controls and/or regulates the electric motor and includes a printed circuit board with a potting compound on which electronic components are arranged. An electrically conductive on the insert shaft allows a releasable electric contact between the battery and the electronic device of the tool by inserting the battery into the insert shaft. The contact is divided into a first and second surface regions. The first surface region is covered with a nonconductive protective layer, and the second surface region is free of the protective layer.
