Arrangement for communicating messages via a low-voltage electricity supply system and adapter
First Claim
1. Arrangement for communicating messages via a low-voltage electricity supply system (9) having at least one phase conductor, a neutral conductor and an earth conductor, comprising at least one apparatus which is suitable at least for receiving or for emitting a carrier signal for the transmission of data, the frequency of which carrier signal is substantially greater than the mains frequency, and is connected to the low-voltage electricity supply system (9) via a plug that is plugged into a mains socket outlet (12), and at least one apparatus which does not participate in the exchange of data, constitutes a possible source of interference and is connected to the low-voltage electricity supply system (9) via a mains plug (11′
- ) and a mains socket outlet (12′
), which is electrically conductively connected to the latter, characterized in that the connection between the mains plug (11′
) of the at least one apparatus constituting a possible source of interference and the mains socket outlet (12′
) is established via an adapter (1) having a plug (3), which is connected to the mains socket outlet (12′
) and, in particular, is plugged into the latter, and at least one socket outlet (4), to which the apparatus is connected via a plug which is plugged into the said socket outlet, which adapter (1) has parallel conductor connections for the individual conductors of the low-voltage electricity supply system (9), and inductance being situated in each of the conductor connections with the exception of the earth conductor connection.

Abstract
A PC (10) connected to a low-voltage electricity supply system (9) via a mains plug (11) and a mains socket outlet (12), into which the said plug is plugged, exchanges messages with other apparatuses via the said electricity supply system by means of signals whose frequency is between 1 MHz and 40 MHz. In order to suppress high-frequency interference signals which are generated by further apparatuses which are connected to the low-voltage electricity supply system (9) via mains plugs (11′) and further mains socket outlets (12′), arranged in local proximity to the said mains socket outlet (12), or which are produced by reflections of signals at open line ends, an adapter (1) is in each case interposed there, which adapter is plugged into the mains socket outlet (12′) and into which adapter the mains plug (11′) of the respective apparatus is plugged. The adapter (1) connects each pin of the mains plug (11′) to a socket of the mains socket outlet (12′), inductor coils which block signals in the frequency range of the message transmission being situated, however, in the phase conductor and in the neutral conductor of the adapter (1).
