Definitions

• the present invention relates to a distributed distribution method of electrical energy based on the intrinsic equipotentiality of the current lead conductor.
• the current technical response consists in interposing equipotential electrical conductors between the current supply conductor and the electric conductors for supplying electrical energy to the subassemblies.
• These equipotential electrical conductors allowing the distribution of electrical energy, generally consist of rigid conductors, such as "bus-bar”, or semi-rigid or flexible conductors, and connectors, terminal block type;
• the terminal blocks themselves may comprise rigid conductors, "bus-bus” type, which terminal blocks are interconnected by rigid, semi-rigid or flexible electrical conductors thus constituting jumpers or "straps".
• the electrical contacts between the various elements to be connected are provided either directly by electrically conductive clamping screws, or by electrically conductive clamps, themselves actuated, either by clamping screws, or by supporting springs.
