摘要: A power tool, which includes a receiving device having at least one receiving element and a power supply unit connectable to the power tool, for example a rechargeable battery, which includes a connecting device, the connecting device having at least one contact element, the receiving device being designed to receive and hold the connecting device, so that the at least one receiving element and the at least one contact element are connectable to each other for establishing an electrical connection. A damping element is provided on at least one contact element, whereby the at least one contact element is movable in a first direction and a second direction as well as relative to the particular receiving element, so that it is possible to counteract a relative movement between the contact element and the particular receiving element when the contact element and the receiving element are connected to each other.

摘要: A power tool includes a receiving device having at least one first and second power consumption element. A power supply unit connectable to the power tool includes a connecting device having at least one first and second power output element, the receiving device being designed to receive and hold the connecting device, so that the power consumption elements and the power output elements are connectable. Both the first and second power consumption elements have a positive pole as well as a negative pole, and both the first and second power output elements have a positive pole as well as a negative pole. The positive pole of the first power consumption element and the positive pole of the second power consumption element as well as the negative pole of the first power consumption element and the negative pole of the second power consumption element are positioned at a distance from each other in at least one first and second direction.

摘要: A hand-held power tool, in particular a hammer drill or a combination hammer, is disclosed. The hand-held power tool includes a tool housing which has a receiving recess designed to replaceably receive a storage battery or a power supply unit. The hand-held power tool has an electric drive motor with a cooling fan. The tool housing has a first vent portion which is located in the receiving recess and through which a volume flow generated by the cooling fan can be guided.

摘要: A hand-held power tool, in particular a hammer drill or combination hammer, is disclosed. The power tool includes a tool housing which has a receiving recess designed to replaceably receive a storage battery or a power supply unit. The hand-held power tool further includes an electric drive motor having a cooling fan and a first vent portion which is located on the tool housing outside the receiving recess and through which a volume flow generated by the cooling fan can be guided. The tool housing has a second vent portion which is different from the first vent portion and which is located in the receiving recess and through which the volume flow generated by the cooling fan can be at least partially guided.

摘要: A plug-in coupling (100) for making electrical contact with an electric drive (90) which is included in a hand-held power tool (200) and has a battery unit (20) which is to be accommodated by the hand-held power tool (200). The plug-in coupling (100) has at least one electrical contact plate (1) which is to be connected to the hand-held power tool (200), and at least one electrical contact spring pair (3) which corresponds to the contact plate (1), wherein the contact spring pair (3) is to be arranged on the battery unit (20) and is to be slid onto the contact plate (1) in the sliding-on direction (AR) and is to be withdrawn therefrom in the withdrawal direction (AB), wherein in the state in which contact is made (ZK) the contact plate (1) and the contact spring pair (3) form a frictionally locking latching-connection pairing.
