| 摘要 |
The invention describes a battery pack for an electrical appliance, in particular for a handheld machine tool, having mechanical coding elements for interaction with corresponding coding elements on an electrical appliance. The coding elements are arranged in relation to one another with respect to a first axis in the insertion direction, a second axis transverse to the insertion direction, and a third axis transverse to the insertion direction and transverse to the second axis in such a way that they form a three-dimensional coding system.
