[0009] The subject matter of the present invention will now be described in more detail in exemplary implementations with reference to the accompanying drawings, in which:

[0010] Figure 1 is a bus bar known in the prior art,

[0011] Figure 2 A view showing a bus bar according to a first embodiment of the present invention.

[0012] Figure 3 A perspective view showing a bus bar according to a second embodiment of the present invention is shown.

[0013] Figure 4 A side view of a bus bar according to a second embodiment of the present invention is shown. DETAILED DESCRIPTION

[0014] Figure 2 - Figure 4 The bus bar according to the present invention shown comprises a main board 1 , a side board 2 , a first mounting board 3 and a second mounting board 4 .

[0015] The first mounting plate 3 has a first end 5 and a second end 6. The first end 5 of the first mounting plate 3 has a first through hole 7. The through hole 7 makes it possible to attach the bus bar using fastening elements such as screws when mounting the bus bar at a desired position.

[0016] The main board 1 is positioned between the side board 2 and the first mounting board 3, wherein the main board 1 is connected to the first mounting board 3 via a first bending area 9. The angle between the first mounting board 3 and the main board 1 is 88-92 degrees, in particular 90 degrees.

[0017] The side plate 2 is positioned between the main plate 1 and the second mounting plate 4 and is perpendicular to the main plate 1 (ie, the angle is between 88 degrees and 92 degrees, in particular, 90 degrees).

[0018] According to the first embodiment of the present invention, the first end 5 of the first mounting plate 3 is twisted 90 degrees relative to the second end 6 of the first mounting plate 3 , so there is a twisted area 8 between the ends of the first mounting plate 3 .

[0019] According to the first embodiment of the present invention, there is a bending area 10 between the side plate 2 and the main plate 1. The bending area 10 has a portion of a material 11 separated from the side plate 2 and the side of the bending area 10 in its central part (see Figure 2 ). This portion of the material 11 is connected to the rest of the busbar only from the side of the main board 1 and is bent into a tongue shape toward the side opposite to the side board 2 and toward the side with the first mounting board 3 (see Figure 2 ). This allows the busbar to be securely mounted to the component to which the busbar is attached. In the bending area 10 , the side plate 2 and the main plate 1 are directly connected via the two narrow side portions of the bending area 10 .

[0020] The second mounting plate 4 is connected to the side plate 2 via a second bending area 12 having a second through hole 13. The second bending area 12 creates a bend of 88-92 degrees, in particular a bend of 90 degrees, between the side plate 2 and the second mounting plate 4, so that the second mounting plate 4 is substantially parallel to the main plate 1. The second through hole 12 also enables the busbar to be mounted using mounting elements such as screws.

[0021] The second embodiment of the present invention is Figure 3 and Figure 4 In this embodiment, the bending area 10 includes three bends 14, 15, 16, wherein two plate portions 17, 18 are defined between the three bends, wherein the first plate portion 17 is bent at an angle of 88 to 92 degrees relative to the second plate portion 18, preferably at an angle of 90 degrees.

[0022] The second mounting plate 4 includes elongated through holes 19 placed parallel to each other, wherein the positions of the through holes 19 are located farther away from the side plate 2 ( Figure 3 ). The end of the bus bar with the elongated cutout (19) forms a built-in heat sink structure for improving heat dissipation from the bus bar.

[0023] All elements of the busbar are made as one continuous part, from one piece of material, where the busbar itself is made of metal. Therefore, the production cost of the busbar is much lower compared to the cost of a busbar made from many parts, since less material is used to produce it. In addition, the assembly process is improved, requiring fewer parts and less time to install the busbar in the desired location.

[0024] When the busbars are made from a single piece of metal, particularly copper, the resistance to current flow is significantly lower and less heat is generated in the current path.

[0025] Preferably, the thickness of the busbar is in the range of 2 mm to 10 mm.
