Abstract

Disclosed is an electrical component of a motor vehicle, having a plastic housing and a conductor track structure which is at least substantially embedded in the plastic housing in the injection-molding method and is intended to provide the electrical connections required for operation. The conductor track structure includes—separate wires which each do not run in a straight line, and that any deviation from a straight course of the wires goes back solely to a corresponding bending operation in terms of manufacturing.

Claims

1. An electrical component of a motor vehicle, having a plastic housing and a conductor track structure which is at least substantially embedded in the plastic housing in the injection-molding method and is intended to provide the electrical connections required for operation, wherein the conductor track structure comprises separate wires which each do not run in a straight line, and wherein any deviation from a straight course of the wires goes back solely to a corresponding bending operation in terms of manufacturing.

3. The electrical component as claimed in claim 1, wherein at least one part of the wires is bent in a three-dimensional manner.

4. The electrical component as claimed in claim 1, wherein at least one part of the wires, projects from the plastic housing for the purpose of making contact.

5. The electrical component as claimed in claim 1, wherein at least sections of at least one part of the wires is respectively subsequently treated.

6. The electrical component as claimed in claim 1, wherein the wires run substantially along a housing wall.

7. The electrical component as claimed in claim 1, wherein the electrical component is in the form of a drive for a window winder, a drive for adjusting a seat, or a motor vehicle lock.

8. The electrical component as claimed in claim 1, wherein the electrical component is in the form of a connection element for connecting the stator windings of an electric motor via the conductor track structure, and wherein the plastic housing forms a substantially annular supporting element for accommodating the conductor track structure, which supporting element is arranged, in the mounted state, coaxially with respect to a motor shaft at an end of the stator.

11. The electrical component as claimed in claim 8, wherein at least sections of the supporting element have annularly running grooves for accommodating the wires.

12. The electrical component as claimed in claim 8, wherein the supporting element has axial guides for the winding ends of the stator windings, and wherein the winding ends run through the guides of the supporting element in the axial direction based on the motor shaft.

13. The electrical component as claimed in claim 8, wherein sections of the wires substantially follow the ring shape of the supporting element and have contact outwardly bent portions for contact with the winding ends.

14. The electrical component as claimed in claim 8, wherein at least one part of the wires has a connection outwardly bent portion for electrically connecting the stator, wherein the stator can be connected to a control unit or the like via the connection outwardly bent portions, and wherein the connection outwardly bent portions are axially oriented.

2. An electrical component of a motor vehicle, having a plastic housing and a conductor track structure which is clipped into the plastic housing and is intended to provide the electrical connections required for operation, wherein the conductor track structure comprises separate wires which each do not run in a straight line, and wherein any deviation from a straight course of the wires goes backs solely to a corresponding bending operation in terms of manufacturing.

9. The electrical component as claimed in claim 2, wherein the supporting element has accommodating parts for the wires of the conductor track structure, and wherein the wires are clipped into the accommodating parts.

10. The electrical component as claimed in claim 2, wherein the supporting element has a top side and an underside which are axially opposite based on the motor shaft, wherein one part of the wires is inserted into the top side of the supporting element, and wherein the other part of the wires is inserted into the underside of the supporting element.

15. A method for producing an electrical component of a motor vehicle, the electrical component having a conductor track structure for providing the electrical connections required for operation, which conductor track structure is at least substantially embedded in the plastic housing in the injection-molding method, wherein the conductor track structure is bent from separate wires before being embedded in the plastic housing, and wherein any deviation from a straight course of the wires goes back solely to a corresponding bending operation.

17. The method as claimed in claim 15, wherein the wires to be bent differently are bent separately on different bending machines.

18. The method as claimed in claim 15, wherein at least sections of at least one part of the wires are respectively subsequently treated.

19. The method as claimed in claim 15, wherein the wires are fixed relative to one another after bending and.

16. A method for producing an electrical component of a motor vehicle, the electrical component having a conductor track structure for providing the electrical connections required for operation, which conductor track structure is at least substantially clipped into the plastic housing, wherein the conductor track structure is bent from separate wires before being clipped into the plastic housing, and wherein any deviation from a straight course of the wires goes back solely to a corresponding bending operation.
