Abstract

A core component is disclosed. In an embodiment, the core component includes at least one edge that has a transition, wherein the transition is asymmetrical.

First claim

The invention claimed is:

1. A core component being a cylinder comprising:
a first surface and a second surface of the cylinder; and
at least one edge having a non-symmetrical transition of the cylinder,
wherein the edge is arranged between the first surface and the second surface,
wherein the second surface extends along a height direction of the cylinder and the first surface extends perpendicular to the height direction, and
wherein the non-symmetrical transition encloses an angle larger than 20° and smaller than 90° with a mathematical extension of the second surface within a material of the core component.

2. The core component according to claim 1 , wherein the non-symmetrical transition in dissimilar directions has dissimilar edge dimensions (x, y).

3. The core component according to claim 1 , wherein the core component comprises a face side comprising a clearance, and wherein the edge with the non-symmetrical transition is provided in the clearance.

4. The core component according to claim 1 , wherein the non-symmetrical transition is configured to reduce mechanical stresses in the core component.

5. The core component according to claim 2 , wherein a ratio of the edge dimensions (x, y) of the non-symmetrical transition in a first direction in comparison to a second direction is equal to or more than 1.2.

6. The core component according to claim 1 , wherein a first edge dimension (x) of the non-symmetrical transition in the height direction is smaller than a second edge dimension (y).

7. The core component according to claim 1 , wherein the core component comprises regions with dissimilar heights, and wherein the edge is located between regions of dissimilar heights.

8. The core component according to claim 1 , wherein the non-symmetrical transition at least in portions has a rectilinear contour.

9. The core component according to claim 1 , wherein the non-symmetrical transition at least in portions has an inwardly bulging shape.

10. The core component according to claim 1 , wherein the non-symmetrical transition at least in portions has an elliptic contour.

11. The core component according to claim 1 , wherein the non-symmetrical transition is free of sharp edges.

12. The core component according to claim 1 , wherein the edge is located on a face side of the core component.

13. The core component according to claim 1 , wherein the core component is configured to receive a further component.

14. The core component according to claim 1 , wherein the edge is configured to route through a wire.

15. A component arrangement comprising:
the core component according to claim 1 ; and
a further component located in the core component.

16. The component arrangement according to claim 15 , wherein the further component is a wire-wound component, and wherein a wire is routed out through the edge of the core component.

17. The core component according to claim 1 , wherein the non-symmetrical transition at least in portions has a parabolic contour.

18. The core component according to claim 1 , wherein the non-symmetrical transition encloses an angle smaller than 5° with a mathematical extension of the first surface within the material of the core component.
