A frame element for the fame of a cabinet for an electrical panel is provided. The frame element includes first and second corner joints and first and second connection elements. The first and second corner joints are each formed as a monolithic body and have first and second arms protruding from a longitudinal elongated element of the monolithic body. The first and second corner joints further include third and fourth arms for connection to additional components of the frame. The third and fourth arms are arranged parallel to each other and lie substantially at right angles to the elongated clement and the first and second arms. The first connection element has an elongated body with opposite ends that are suitable for connection to first arms of the first and second corner joints. The second connection element has an elongated body with opposite ends that are suitable for connection to second arms of the first and second corner joints. Coupling means are provided on the first and second corner joints to facilitate the connection of the first and second corner joints to the first and second connection elements and to the additional components of the frame.

1. A frame element for the frame of a cabinet for an electrical panel, said frame element comprising:a first corner joint and a second corner joint which are each formed as a monolithic body which has a longitudinal elongated element from the opposite ends of which a first arm and a second arm protrude, said first and second arms being substantially parallel to each other and perpendicular to the elongated element, and a third arm and a fourth arm for connection to additional components of the frame, said third and fourth arms being arranged substantially parallel to each other and lying substantially at right angles to the elongated element and to the first and second arms;a first connection element which has an elongated body whose opposite ends are suitable to be connected respectively to the first arm of the first corner joint and to the first arm of the second corner joint;a second connection element which has an elongated body whose opposite ends are suitable to be connected respectively to the second arm of the first corner joint and to the second arm of the second corner joint;coupling means which are located on said first and second corner joints, said coupling means being suitable to facilitate connection of said first and second corner joints to said first and second connection elements and to said additional components of the frame,said first, second, third and fourth arms having mutually identical profiles with a substantially flat wall from which two oblique walls protrude in mutually opposite directions, said first and second connection elements each having a hollow profiled body with a flat wall from which two oblique walls protrude in substantially opposite directions, said hollow profiled body forming a seat which is suitable to accommodate a portion of a corresponding one of said first and second arms of said first and second corner joints. 2. The frame element according to claim 1, wherein said coupling means are formed on said first and second corner joints and are suitable to facilitate direct engagement of said first and second corner joints with said first and second connection elements. 3. The frame element according to claim 2, wherein said flat walls of said first and second arms have at least one protrusion which protrudes transversely there from, said protrusion being suitable to engage in the corresponding seat formed in the ends of said first and second connection elements. 4. The frame element according to claim 3, wherein said protrusion has a first base surface which is formed in said flat wall, a second end surface which lies opposite the base surface along a plane which is inclined with respect to said flat wall, and a third surface for connection between said first and second surfaces which forms an abutment surface for at least one portion of a rim of the corresponding seat. 5. The frame element according to claim 2, wherein said flat walls of at least said first and second arms have a U-shaped cutout central portion from a base surface of which at least one flexible tab protrudes in a direction which is substantially parallel to said wall, said tab having an end which is shaped so as to engage in the corresponding seat formed in said connection elements. 6. The frame element according to claim 5, wherein said shaped end has a raised portion which has a substantially circular cross-section and has a first base surface which is fixed to the tab, an end surface which lies opposite the base surface substantially on a plane which is inclined with respect to the flat wall, and a third surface which connects said base and end surfaces for the abutment of a portion of the edge of the corresponding seat. 7. The frame element according to claim 1, wherein said coupling means are formed on said first and second corner joints and are suitable to facilitate direct engagement of said first and second corner joints with said additional connection elements. 8. The frame element according to claim 7, whe rein said flat walls of said third and fourth arms have at least one protrusion which protrudes transversely there from, said protrusion being suitable to engage in the corresponding seat formed in said additional components of the frame. 9. The frame element according to claim 8, wherein said protrusion has a first base surface which is formed in said flat wall, a second end surface which lies opposite the base surface along a plane which is inclined with respect to said flat wall, and a third surface for connection between said first and second surfaces which form an abutment surface for at least one portion of a rim of the corresponding seat. 10. The frame element according to claim 7, wherein said flat walls of said third and fourth arms have a U-shaped cutout central portion from a base surface of which at least one flexible tab protrudes in a direction which is substantially parallel to said wall, said tab having an end which is shaped so as to engage in the corresponding at formed in said additional components of the frame. 11. The frame element according to claim 1, wherein said coupling means comprise at least two cavities which are formed in said first and second arms and are suitable to accommodate means for engagement with said first and second connection elements. 12. The frame element according to claim 11, wherein said engagement means comprise a flat plate which has a substantially quadrilateral profile and from two sides of which two wings protrude in mutually opposite directions, said wings being suitable to engage in corresponding slots formed in the corresponding connection element and to geometrically couple in said cavities, a hole being formed in said plate, said hole being suitable to accommodate a threaded screw which can be inserted in a corresponding hole formed in the corresponding connection element and to be screwed into a threaded hole formed in the arm of the joint. 13. The frame element according to claim 1, wherein said coupling means comprise two cavities which are formed in said third and fourth arms and are suitable to accommodate means for engagement with said additional components of the frame. 14. The frame element according to claim 13, wherein said engagement means comprise a flat plate which has a substantially quadrilateral profile and from two sides of which two wings protrude in mutually opposite directions, said wings being suitable to engage in corresponding slots formed in said additional components of the frame and to geometrically couple in said cavities, a hole being formed in said plate, said hole being suitable to accommodate a threaded screw which can be inserted in a corresponding hole formed in the additional components of the frame and can be screwed into a threaded hole formed in the arms of the joint. 15.
