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

1 - 24 . (canceled)

25 . 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 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, 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.

26 . The device according to claim 25 , wherein the shaping arrangement has a base face, on which the wire rests, and at least one side wall, wherein the at least one side wall has a curved course, and wherein the shaping arrangement is formed in such a way that the wire as it is advanced in the shaping arrangement is bent along the side wall.

27 . The device according to claim 26 , wherein the shaping arrangement is open on a side opposite the base face.

28 . The device according to claim 26 , 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 in such a way 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.

29 . The device according to claim 26 , further comprising:
at least one displaceable cover arrangement; wherein the shaping arrangement is open on a side opposite the base face; and 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.

30 . The device according to claim 25 , 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 in such a way that the wire, as it is advanced, is slid from the guide arrangement into the shaping arrangement.

31 . The device according to claim 30 , 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.

32 . The device according to claim 25 , wherein the pitch-producing arrangement is arranged in such a way that the wire, as it is advanced in the shaping arrangement, is guided to the pitch-producing arrangement following the bending in the shaping arrangement.

33 . The device according to claim 25 , 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.

34 . The device according to claim 25 , 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 in such a way 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.

35 . The device according to claim 25 , further comprising a pre-bending arrangement configured to bend an end portion of the wire, wherein the wire is clampable in the advancing arrangement in such a way that the end portion of the wire protrudes from the advancing arrangement, wherein the pre-bending arrangement is formed in such a way that the end portion of the wire protruding from the advancing arrangement is movable to the shaping arrangement following the bending by the pre-bending arrangement.

36 . The device according to claim 35 , wherein the pre-bending arrangement has a guide for receiving the wire, wherein the pre-bending arrangement is formed in such a way 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.

37 . A method for winding a wire for an inductive component, the method comprising:
advancing the wire in a device in such a way that the wire is fed to a shaping arrangement and a pitch-producing arrangement; and bending the wire as the wire is guided through the shaping arrangement and the pitch-producing arrangement in such a way that the wire is bent in a coiled manner.

38 . The method according to claim 37 , further comprising:
arranging a closed core of an inductive component in a receiving arrangement in order to position the core; and winding the wire around a leg of the closed core by advancing the wire in the shaping arrangement and the pitch-producing arrangement.

39 . An inductive component producible according to claim 13 .

40 . The inductive component according to claim 39 , wherein the winding of the wire is compressed.

41 . An inductive component comprising:
a winding of a wire, wherein the wire is wound in a circular manner with a pitch, and wherein the winding of the wire is compressed.

42 . The inductive component according to claim 41 , wherein the inductive component has a closed core.

43 . The inductive component according to claim 42 , wherein the core in a cross section has an outer peripheral line which is not circular.

44 . The inductive component according to claim 41 , wherein the wire is formed as a rectangular, flat or round wire.
