Underwater electrical connection system

An undersea connection system for electrically connecting together in sealed manner at least three high voltage or very high voltage undersea electric cables, the system being of the type in which:

• each electric cable comprises a main conductor surrounded by at least one main insulating sheath, itself surrounded by metal armor;
• and
• each electric cable presents a connection end at which the main conductor presents a visible end that projects axially beyond the corresponding end of the main insulating sheath, and beyond an end of the metal armor;
• and of the type in which the system includes:
• an outer cage that defines a connection space, the cage having cable-passing inlets for passing electric cables to be connected together electrically;
• and
• a connection fitting received in the connection space and comprising a conductive connection electrode that presents a junction node from which there extend at least three branches, each branch being for connecting electrically to the connection end of a respective one of the electric cables to be connected together electrically;
• wherein:
• each of said at least three branches of the conductive electrode includes a male terminal portion;
• each of said at least three branches of the electrode is electrically connected, inside the connection space, to the connection end of a respective one of the electric cables in a connection zone around which there is mounted a connection sleeve comprising an outer tubular sleeve of pre-molded insulating material that presents a bore opening out at its two opposite axial ends so as to receive, in the assembled position, via its respective ends firstly the male terminal portion of one of the branches of the conductive electrode, and secondly the connection end of one of the electric cables.
