[0002] In view of the above-mentioned circumstances, the object of the invention is to provide a power electronic arrangement with individual line elements for simple assembly and production.
[0003] This object is achieved according to the invention by a power electronic arrangement with a first conducting element with a first planar section with a first normal direction, a second conducting element and a connecting element electrically connecting this with a second planar section with a second normal direction, wherein the first planar portion has a plurality of slot-like recesses, wherein holding elements of the second planar portion interact with the slot-like recesses and thus define an axis of rotation orthogonal to the second normal direction, and wherein a rotation limiting element protrudes orthogonally to the axis of rotation and to the second normal direction in the negative direction from the second planar portion, having the following features.
[0004] In this case, it may be advantageous if the first conducting element is designed as a connection element of a capacitor or as a connection element of a power semiconductor module or as a connection element of a busbar.
[0005] It may also be advantageous if the holding element is designed such that a distance is formed between the first and second flat portions.
[0006] It can generally be advantageous if the holding element protrudes as a T-shaped attachment in the negative second normal direction from the second flat section.
[0007] It may also be advantageous if the rotation limiting element is designed as a tab.
[0008] It may be preferred if a second line element has a third planar section on which a fourth planar section of the first line element rests.
[0009] It may also be advantageous if the first line element is connected to the second line element by welding or by means of a soldering connection or by means of clamping.
[0010] It may also be advantageous if a third line element is arranged next to the first line element, wherein the second line element overlaps the other two line elements at least in sections.
[0011] It may also be advantageous if an insulating foil is arranged at least in sections between the second and the third line element.
[0012] It may also be preferred if an insulating foil is arranged at least in sections between the first and third line elements.
[0013] It may also be advantageous if an insulating foil is arranged at least in sections between the first and second line elements.
[0014] It may also be advantageous if the second line element securely positions an insulation foil by means of the holding element.
[0015] Of course, unless this is explicitly or per se excluded or contradicts the idea of the invention, the features or groups of features mentioned in the singular, for example holding elements, can be present multiple times in the assembly according to the invention or the power semiconductor device.
[0016] It is understood that the various embodiments of the invention, regardless of whether they are mentioned in connection with the power electronic arrangement, can be implemented individually or in any combination to achieve improvements. In particular, the features mentioned and explained above and below can be used not only in the specified combinations, but also in other combinations or on their own, without departing from the scope of the present invention.

The holding element 21 is preferably at an angle of 70° to 110° to the flat section 20, particularly preferably at an angle of 90°.

The second conducting element 2 extends essentially in a first normal direction y and a third normal direction x. The at least one holding element 21 of the second conducting element 2 is arranged in the slot-like recess 12 of the first conducting element 1.

An L-shaped angled first conducting element 1 extends in a first normal direction y, as well as in a negative second normal direction z. An L-shaped angled third conducting element 3 extends in a first normal direction y, as well as in a negative second normal direction z. The first conducting element 1 and third conducting element 3 meet in a preferably vertical region and run at least partially spaced from one another. A second conducting element extends essentially in the second normal direction y and at least partially overlaps the first and third conducting elements 1, 3. Insulation in the form of an insulating film can be arranged between the conducting elements. The individual conducting elements can preferably have a distance from one another which prevents electrical contact between the conducting elements.It may also be preferred for the second line element to be electrically conductively connected, at least in sections, to the first or third line element. The connection between two line elements can be implemented using known joining methods such as a welded joint, in particular a laser welded joint, or by soldering or clamping.

A third flat section 23 of the second conduit element 2 lies parallel to the fourth flat section 13. A retaining element 21 of the second conduit element 2 is located in the slot-like recess 12 of the first conduit element 1. An extension 25 of the retaining element 21 secures the position of the second conduit element 2 relative to the first conduit element. The extension 25 presses against the first conduit element in the second normal direction z.
