Shielded busbar

A shielded busbar comprising a casing having a duct housing a conductor pack including three or more conductors arranged side by side, wherein each conductor extends along a longitudinal axis and has a rectangular cross-section, thereby each conductor has two primary lateral surfaces, which are opposite to each other, and two secondary lateral surfaces, which are opposite to each other, wherein each pair of adjacent conductors of the conductor pack are arranged side by side along respective primary lateral surfaces, wherein the shielded busbar further comprises two or more shielding elements extending along said longitudinal axis and made of magnetically shielding material, wherein each one of said two or more shielding elements comprises or consists of a primary plate that entirely overlaps a primary lateral surface of one or two of said three or more conductors, and wherein not more than one shielding element of said two or more shielding elements has a C-shaped cross-section;

• wherein said two or more shielding elements include a first shield in the first shielding element, its primary plate is joined at one of its two longitudinal edges to a secondary plate that is orthogonal to the primary plate, wherein the primary plate entirely overlaps the primary lateral surface of one of the two conductors arranged at the ends of the conductor pack, and wherein the secondary plate entirely overlaps adjacent secondary lateral surfaces of all said three or more conductors of the conductor pack;
• in second shielding element, its primary plate is joined at one of its two longitudinal edges to a secondary plate that is orthogonal to the primary plate, wherein the primary plate entirely overlaps the primary lateral surface of the other one of the two conductors arranged at the ends of the conductor pack, and wherein the secondary plate entirely overlaps the adjacent secondary lateral surfaces of all said three or more conductors of the conductor pack which are opposite to the adjacent secondary lateral surfaces entirely overlapped by the secondary plate of the first shielding element;
• wherein the primary plate of the second shielding element is further joined at the other one of its two longitudinal edges to an additional secondary plate that is orthogonal to the primary plate, wherein the additional secondary plate entirely overlaps the adjacent secondary lateral surfaces of all said three or more conductors of the conductor pack also entirely overlapped by the secondary plate of the first shielding element, and wherein the two secondary plates joined to the primary plate of the second shielding element are joined to respective end fins, which are orthogonal to the respective secondary plates, wherein the end fins partially overlap the primary lateral surface of the other one of the two conductors arranged at the ends of the conductor pack.
