The present invention provides an inductive component () in several illustrative embodiments and a method for producing such an inductive component. The inductive component () comprises a bus bar () and at least one magnetic core () which is formed along a section of the bus bar () and surrounds the bus bar () in that section at least in part, wherein the at least one magnetic core () is formed as a plastic-bonded magnetic core or a core made of magnetic cement.

Inductive component

A ferrite core comprising a yoke body having a length dimension, a width dimension and a height dimension, which are oriented perpendicular to one another, the length dimension being larger than the height dimension and/or the width dimension. A lateral surface of the yoke body has provided therein a positioning structure and an alignment structure, which differs from the positioning structure, the positioning and alignment structures being spaced apart along the length dimension by 5% to 75% of the length dimension.

Ferrite core, inductive component and method of producing an inductive component

The present invention provides a method of forming a frame core () having a center leg () for an inductive component, and an accordingly formed frame core () having a center leg () and an air gap () in the center leg (). The frame core () is formed integrally with the center leg (), the air gap () being molded into the center leg () during the formation of the frame core ().

Method for forming a frame core having a center leg for an inductive component and frame core produced accordingly

In various aspects, a plate-shaped leakage structure as an insert in a magnetic core of an inductive component, a magnetic core having a plate-shaped leakage structure, and an inductive component. In illustrative embodiments, a plate-shaped leakage structure is provided as an insert in a magnetic core, which is passed through, along the thickness direction thereof, by at least one spacer having a very low magnetic permeability (as opposed to the rest of the material of the leakage structure). In a magnetic core according to an aspect, core legs are arranged above opposite bearing surfaces of the plate-shaped leakage structure, the plate-shaped leakage structure providing a leakage path between the core legs.

Plate-shaped leakage structure as an insert in a magnetic core

Core bodies which have an alignment structure and allow an alignment during the production of magnetic cores irrespective of production tolerances, in which the production tolerances are compensated. In illustrative embodiments a core body of ferromagnetic material comprises a crossbar having an aspect ratio of length to width greater than 1, and at least one core leg extending laterally away from the crossbar along an extension direction. An alignment recess is formed in a rear surface of the crossbar, which is arranged on a side of the crossbar opposite the core legs. A magnetic core is formed of core bodies, whereby at least one core body is provided with an alignment recess, and the core bodies are aligned relative to one another.
