Battery charging device for cordless telephone

摘要

The battery charging device has one part (22, 23, 28) incorporated in the base station (2) for the cordless telephone handset (1), which is connected to the telephone network (3) and the mains current supply network (4) and a second part (14, 15) incorporated in the handset itself. The electrical energy is transferred between the 2 parts via an inductive or capacitive coupling when the telephone handset is in a defined position relative to the base station, with the holder or mounting (20) for the handset housing part of this coupling, which also provides the antenna for the radio link between the base station and the handset.
