Claims

1. A bus bar assembly system comprising a bus bar for electric power distribution, and connection and fixing means, wherein said bus bar comprises a body made of conducting material, said body having, on at least one side, at least one slot having a C-shaped cross-section, a back wall of said C-shaped slot comprising two substantially straight portions which form an angle of less than 180° between them, and wherein said connection and fixing means comprise a T-shaped bolt having a head inserted in said C-shaped slot, the coupling between said bolt and said bus bar occurring by means of the interference between the head of the bolt and the substantially straight portions of the back wall of said C-shaped slot.

2. The bus bar for electric power distribution according to claim 1, wherein said body has a substantially quadrangular transverse cross-section.

3. The bus bar according to claim 1, wherein said body has two C-shaped slots, a first slot being formed on a first side of the body, a second slot being formed on a second side of the body, the first and second sides being substantially parallel to each other.

4. The bus bar according to claim 1, wherein said body has three C-shaped slots, a first slot and a second slot being formed on two substantially parallel sides of the body, a third slot being formed along a third side of the body, said third side being substantially perpendicular to said first and second sides.

5. The bus bar according to claim 1, wherein said body has five C-shaped slots, a first slot and a second slot being formed along a first side of the body, a third slot and a fourth slot being formed along a second side of the body, said first and second sides being substantially parallel to each other, a fifth slot being formed on a third side of the body which is substantially perpendicular to said first and second sides.

6. The bus bar according to claim 1, wherein said body has six C-shaped slots, a first slot and a second slot being formed along a first side of the body, a third slot and a fourth slot being formed along a second side of the body, said first and second sides being substantially parallel to each other, a fifth slot and a sixth slot being formed respectively on a third side and on a fourth side, said third and fourth sides being substantially parallel to each other and being perpendicular to the first side and to the second side.

7. An electric power distribution switchboard comprising a plurality of electrical devices, such as circuit breakers and the like, which are electrically connected to corresponding bus bars, wherein at least one of said bus bars comprises a body made of conducting material, wherein said body has, on at least one side, at least one slot having a C-shaped cross-section, a back wall of said C-shaped slot comprising two substantially straight portions which form an angle of less than 180° between them.

8. The bus bar for electric power distribution according to claim 1, wherein said two substantially straight portions form an angle comprised between 155° and 178°.

9. The bus bar for electric power distribution according to claim 8, wherein said two substantially straight portions form an angle comprised between 160° and 175°.

10. The bus bar for electric power distribution according to claim 9, wherein said two substantially straight portions form an angle comprised between 165° and 172°.
