Abstract

A system is provided for mechanically coupling an electrical supply unit for cordless electrical devices with a charging device, the electrical supply unit includes a housing in which at least one battery that can be recharged by the charging device is located, an associated electrical supply unit, and an associated charging device. At least one guide element is located in the front region of the housing of the electrical supply unit, which engages, for mechanical coupling with the charging device, in a corresponding receiving device on the charging device; the combination of the at least one guide rail and the receiving device functions as a flexible coupling or a slide-in, rear-engagement seat.
