Abstract

A battery-powered hand-guided power tool is provided, such as a hammer, includes a tool housing 3 that contains an electric motor M, a grip housing 2 and a rail-and-channel structure 36,37,54,55 for releasable mounting of a rechargeable battery pack 50. The battery pack 50 is locked in an operative position on the housing 3 in which electrical contacts (51) of the battery pack 50 and associated electrical contacts 42 of the tool housing are electrically connected along a contact length extending in a longitudinal direction of the rail-and-channel arrangement. A latch structure 18,19 located on the tool housing 3 is movable between a latched position and a release position. When the latch structure 18,19 is moved from the latched position into the release position, the battery pack 50 can be moved in the direction of the longitudinal extent of the rail-and-channel structure 36,37,54,55 out of the operative position and can be removed from the tool housing 3. Between the battery pack 50 and the tool housing 3 there is arranged a spring 38 which loads the inserted battery pack 50 in a direction of a displacement movement out of the operative position. The distance of travel of the spring 38 is greater than the contact length of the contacts 42,51 and the restoring force of the spring 38 at the contact length is greater than the weight of the battery pack 50.
