Definitions

  • the invention relates to a modified toroid Use in an electromagnetic component.
  • it is about a suitable for surface mounting Core (SMD-capable core).
  • SMD Surface-Mounting Device, surface-mountable component
  • the invention is therefore based on the object modified toroidal core for use in an electromagnetic Provide component that is particularly simple and is reliably SMD-compatible and which is a comparison of the assembled electromagnetic component is not prevented.
  • this object is achieved by a modified toroid according to claim 1, a modified Ring core according to claim 3 and a modified ring core according to Claim 4.
  • a very particularly advantageous and preferred embodiment of the modified toroid according to the invention Claim 1 is the subject of claim 2.
  • the design of the Special volumes according to claim 2 causes the modified Toroidal core essentially the same electromagnetic Maintains properties like a normal toroid of the same diameter. Recalculations of electronic circuits So are not necessary if you are from one used ring core according to the modified ring core Claim 2 passes as long as the diameter remains unchanged leaves.
  • a modified toroidal core according to the invention is used for Use in an electromagnetic component, e.g. B. in a transformer, as shown in Fig. 1.
  • the core is designed in one piece so that the core shape on two surface areas 1, 2 in the manner of the ring cylinder shape deviates that in a first area 1 the ring cylinder shape is flattened in the manner of a smooth cut and is in a platform 2 with a platform-shaped projection smooth surface rises above the normal ring cylinder shape.
  • FIGS. 1 to 3 of the modified toroid according to the invention corresponds that of the normal ring cylinder shape in the first area 1 is missing Volume in size essentially the volume that the normal ring cylinder shape due to the platform-shaped projection in the second area 2 is added.
  • FIGS. 1 to 3 Embodiment of the first area 1 and the second area 2 arranged opposite each other.
  • the length of the core is less than its diameter.
  • the invention is not based on such aspect ratios limited.
  • one modified toroid according to the invention is the length of the Kernel larger than or equal to its diameter.
  • first area 1 as a mounting surface for gluing the core a mounting surface
  • second area 2 serves as Suction area for a normal pipette.
