System for electrically connecting cabin equipment of an aircraft to a control system and to at least one electrical power supply source of the aircraft

A system for electrically connecting a piece of cabin equipment of an aircraft to a control system and to at least one electrical power supply source of the aircraft, the connection system comprising:

• a host interface module to which the control system and the at least one electrical power supply source are connected, the host interface module configured to ensure a conversion of data signals originating from the control system and a transfer of voltages from the at least one power supply source to power supply/data signals that conform to a given protocol, the power supply/data signals being provided at terminals of a host connector;
• an equipment interface module integrated in the cabin equipment, the interface module being connected to an equipment connector and to at least one electrical service element of the cabin equipment, the equipment interface module ensuring a conversion of the power supply/data signals conforming to the given protocol that are present on the equipment connector to control data signals for controlling the at least one electrical service element and a transfer of the voltages from the at least one power supply source to the at least one electrical service element, and
• a cable connected by its ends to the host connector and the equipment connector, thereby ensuring a connection of the host interface module and the equipment interface module for exchange of the control data signals, and the host interface module and the equipment interface module, respectively, comprising radiofrequency communication units configured to exchange control data signals with one another when at least one of the host interface module and the equipment interface module has detected an interruption in the exchange of the control data signals via the cable.
