  • Patent number: 10832852
    Abstract: 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.
    Type: Grant
    Filed: May 26, 2017
    Date of Patent: November 10, 2020

  • Patent number: 9620277
    Abstract: 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.
