Abstract

An inductive component, a device, and a method for winding a wire for an inductive component are disclosed. In an embodiment a device includes an advancing arrangement configured to advance a wire and a shaping arrangement and a pitch-producing arrangement configured to bend the wire, wherein the shaping arrangement and the pitch-producing arrangement are arranged in such a way that the wire, as it is advanced by the advancing arrangement, is introduced into the shaping arrangement and the pitch-producing arrangement, and wherein the shaping arrangement and the pitch-producing arrangement are formed in such a way that the wire, as it is advanced, is bent in a coiled manner in the shaping arrangement and the pitch-producing arrangement.

First claim

The invention claimed is:

1. A device for winding a wire for an inductive component, the device comprising:
an advancing arrangement configured to advance the wire; and
a shaping arrangement and a pitch-producing arrangement configured to bend the wire,
wherein the shaping arrangement and the pitch-producing arrangement are arranged such that the wire, as it is advanced by the advancing arrangement, is introduced into the shaping arrangement and the pitch-producing arrangement,
wherein the shaping arrangement and the pitch-producing arrangement are formed such that the wire, as it is advanced, is bent in a coiled manner in the shaping arrangement and the pitch-producing arrangement,
wherein the shaping arrangement has a base face for supporting the wire and at least one side wall,
wherein the at least one side wall has a curved course,
wherein the shaping arrangement is formed such that the wire, as it is advanced in the shaping arrangement, is bent along the side wall,
wherein the shaping arrangement is open on a side opposite the base face such that a coil protrudes out of the shaping arrangement at a side opposite of the base face, and
wherein the shaping arrangement is not located between adjacent windings in a protruding part.

2. The device according to claim 1 , wherein the shaping arrangement is designed to guide a flat wire, which has a larger side face and a smaller side face, and wherein the shaping arrangement is formed such that the flat wire, as it is guided and bent in the shaping arrangement, rests via the larger side face on the base face of the shaping arrangement and bears via the smaller side face on the side wall of the shaping arrangement.

3. The device according to claim 1 , further comprising at least one displaceable cover arrangement, wherein the cover arrangement is designed to be displaceable into a position in which the cover arrangement covers the shaping arrangement on the side opposite the base face.

4. The device according to claim 1 , further comprising a guide arrangement for guiding the wire in a plane (E), wherein the guide arrangement has a straight course in the plane (E), wherein the guide arrangement and the shaping arrangement are arranged such that the wire, as it is advanced, is slid from the guide arrangement into the shaping arrangement.

5. The device according to claim 4 , wherein the shaping arrangement and the guide arrangement are formed as part of a plate, wherein the plate is arranged after the advancing arrangement in an advancing direction of the wire, wherein the shaping arrangement has a first indentation in the plate with a curved course in the plane (E) of the plate, and the guide arrangement has a second indentation in the plate with a straight course in the plane of the plate, and wherein the first indentation within the plate directly adjoins the second indentation.

6. The device according to claim 1 , wherein the pitch-producing arrangement is arranged such that the wire, as it is advanced in the shaping arrangement, is guided to the pitch-producing arrangement following bending in the shaping arrangement.

7. The device according to claim 1 , wherein the pitch-producing arrangement is integrated in the shaping arrangement, such that the wire, as it is bent in the shaping arrangement, is also provided with a pitch at the same time.

8. The device according to claim 1 , further comprising a receiving arrangement for positioning a core of an inductive component in the device, wherein the shaping arrangement and the pitch-producing arrangement are arranged around the receiving arrangement such that the wire is wound in a coiled manner around the core of the inductive component when the core of the inductive component is positioned in the receiving arrangement and the wire is guided through the shaping arrangement and the pitch-producing arrangement.

9. The device according to claim 1 , further comprising a pre-bending arrangement configured to bend an end portion of the wire, wherein the wire is clampable in the advancing arrangement such that the end portion of the wire protrudes from the advancing arrangement, wherein the pre-bending arrangement is formed such that the end portion of the wire protruding from the advancing arrangement is movable to the shaping arrangement following bending by the pre-bending arrangement.

10. The device according to claim 9 , wherein the pre-bending arrangement has a guide for receiving the wire, wherein the pre-bending arrangement is formed such that the pre-bending arrangement is displaceable from a first position at a distance from the end portion of the wire protruding from the advancing arrangement into a second position, in which the end portion of the wire protruding from the advancing arrangement lies in the guide of the pre-bending arrangement.
