Abstract

A connection device for connecting an electrical member to a communications line comprising at least two conductors for carrying differential signals. The connection device includes at least one data exchange interface component connected to the line to send and/or receive data, and a connection for connecting the electrical member to the line. The connection device also includes in succession, going from the connection to the interface components, at least a first transformer arranged to perform common mode filtering on each conductor of the communications line; a second transformer arranged to perform electrical isolation so as to isolate the communications line at least from the interface component; a third transformer connected in parallel with the second transformer and made up of two windings having terminals including terminals that are not connected to the second transformer and that are connected to frame ground of the electrical member; and a fourth transformer arranged to provide electrical isolation so as to isolate at least the interface component from frame ground.
