A part of a current path is for an electric switching device. In an embodiment, the part of the current path was produced in layers by way of a 3D printing method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A current path part for an electrical switching device, the current path part comprising: a layer-by-layer portion produced by a 3D printing method; and at least one cavity having a cross section having a circular shape or a triangular shape. 2. The current path part of claim 1 , wherein the layer-by-layer portion includes at least two different materials. 3. The current path part of claim 2 , wherein the at least two different materials differ in terms of at least one of mechanical strength, electrical conductivity, or magnetic properties. 4. The current path part of claim 3 , wherein a cross section of the current path part is at least one of a rectangular shape, a trapezoid shape, a T-support shape, or a double T-support shape. 5. The current path part of claim 2 , wherein a cross section of the current path part is at least one of a rectangular shape, a trapezoid shape, a T-support shape, or a double T-support shape. 6. The current path part of claim 2 , further comprising a prefabricated component portion integrated on or in the layer-by-layer portion. 7. The current path part of claim 6 , wherein the prefabricated component portion includes an axle or a bearing bush. 8. The current path part of claim 2 , wherein the current path part includes a material including a plurality of zones, the plurality of zones having different physical properties from each other. 9. The current path part of claim 2 , wherein the current path part is a contact lever, a fixed contact or a busbar. 10. The current path part of claim 9 , wherein the current path part is the contact lever and includes at least one integrated contact surface. 11. The current path part of claim 1 , wherein a cross section of the current path part is at least one of a rectangular shape, a trapezoid shape, a T-support shape, or a double T-support shape. 12. The current path part of claim 1 , further comprising a prefabricated component portion integrated on or in the layer-by-layer portion. 13. The current path part of claim 12 , wherein the prefabricated component portion includes an axle or a bearing bush. 14. The current path part of claim 1 , wherein the current path part includes a material including a plurality of zones, the plurality of zones having different physical properties from each other. 15. The current path part of claim 14 , wherein the difference in the physical properties of the plurality of zones include differing conductivity. 16. The current path part of claim 1 , wherein the current path part is a contact lever, a fixed contact or a busbar. 17. The current path part of claim 16 , wherein the current path part is the contact lever and includes at least one integrated contact surface. 18. The current path part of claim 1 , wherein a shape of a cross section of the current path part changes along a length of the current path part. 19. A current path part for an electrical switching device, the current path part comprising: a layer-by-layer portion produced by a 3D printing method; and a prefabricated component portion integrated on or in the layer-by-layer portion, the prefabricated portion including at least one of an axle or a bearing bush.
