Connection system for establishing electrical connection between electrical device for automotive industry and at least one pair of cables

A connection system (5a, 5b) for establishing an electrical connection between an electrical device (3) and at least one pair of cables (4, 7) each of which ends with a cable terminal, the connection system (5a, 5b) comprising:

• a fixed part (10) including a support base (11) that is adapted to be rigidly fitted to a wall (12) of the electrical device (3) and, for each of the cables (4, 7), a connection screw (13) that protrudes from the support base (11) and can be electrically connected to the-electrical device (3);
• and
• a mobile part (15) including a perimeter frame (16) that is adapted to be mechanically fitted to the support base (11) and having a passage wall (17) that comprises, for each of the cables (4, 7), a passage-through hole (18) through which an end part of the cable (4, 7) passes so that the corresponding cable terminal is disposed inside the perimeter frame (16) and aligned with the respective connection screw (13) when the perimeter frame (16) is mechanically fitted to the support base (11);
• wherein the perimeter frame (16) has a rectangular shape and comprises only four walls including:
• the passage wall (17) provided with the passage-through holes (18), two lateral walls (25) arranged perpendicular to the passage wall (17) and on opposite sides of the passage wall (17), and an end wall arranged parallel and opposite to the passage wall (17);
• wherein each of the cables (4, 7) is made integral to the passage wall (17) to avoid relative movements between the cables (4, 7) and the perimeter frame (16) before mechanically fitting the perimeter frame (16) of the mobile part (15) to the support base (11) of the fixed part (10);
• wherein the mechanical connection between the perimeter frame (16) of the mobile part (11) and the support base (11) of the fixed part (10) also determines the contemporaneous coupling of the cable terminals of the cables (4;
• 7) to the connection screws (13);
• and
• wherein the cables (4, 7) define different lengths of the cables (4, 7) inside the perimeter frame (16) to increase distance between the cable terminals.
