Plurality of plugs with locking levers coupled to a plurality of sockets formed integrally with an electrical equipment box panel

A connection system comprising:

• a plurality of connection plugs on each of which is mounted a locking lever with two arms each one supporting a locking hook of a locking system,
• an assembly comprising:
• an electrical equipment box panel, designed to lodge an electronic circuit card, the electrical equipment box panel comprising a plurality of openings;
• a plurality of adjacent sockets, each one comprising a hollow tubular portion forming a rim projecting relative to the electrical equipment box panel on an equipment side opposite the side where the electronic circuit card is arranged, each rim bearing two locking lugs of the locking system of a plug for locking to one of the sockets in a mutual connection configuration, cavities of the tubular portions of the sockets defining openings of the electrical equipment box panel;
• wherein the plurality of sockets is monobloc with the electrical equipment box panel and in that the sockets of the assembly and the plugs are configured such that when each plug is connected to one of the sockets and locked to the latter by means of the locking lever in a position of attachment of the hooks to the locking lugs, two adjacent anus of adjacent plugs are in a planar, point like or linear bearing against each other.
