Abstract
Abstract An electric supply device for the cordless operation of electrical appliances has a holder fixed to the electrical appliance for detachably locking and substantially exposing a mounting support of a storage unit. For electrical contact connection, approximately in the plane of a countersunk bearing surface, the storage unit has flat, rigid contacting contacts, with which are associated corresponding countercontacting contacts in the vicinity of the associated counterbearing surface of the holder. The contacting contacts are proximate to a hinge axis formed by a projecting hinged cam and a cam pocket between the storage unit and the holder, so that a favorable leverage is obtained. For detachable locking, two separately, but simultaneously, operable locks are provided in the vicinity of the other end of the storage unit, in which the holder is substantially embedded.
