Abstract
The invention is directed to an adapter plug in combination with a rechargeable electric appliance for personal use, such as a dry shaving apparatus, the adapter plug equipped with flat contact pins, having a plug case with contact pins for connecting to a socket-outlet and a case wall provided with accommodating holes suitable for receiving flat contact pins of the electric appliance in order to close a circuit, said accommodating holes being associated with a safety wall projecting from the case wall, in such fashion that during the process of inserting the flat contact pins in the accommodating holes the relative distance of the accommodating holes or of the flat contact pins of the electric appliance to the safety wall is at least equal to or greater than the safety clearance to be maintained to prevent voltage flashover. The safety wall has at least one recess for accommodating a housing of the electric appliance.
