Abstract
Description
Die Erfindung betrifft ein induktives Miniatur-Bauelement für SMD-Montage mit einem einteiligen Ferritkern, der in einen mindestens eine Spulenwicklung tragenden Wicklungsträger aus Kunststoff eingesetzt ist, welcher als im Wesentlichen rechteckiger, aus zwei Längsbalken und zwei Querbalken aufgebauter Rahmen ausgebildet ist, wobei der Ferritkern zwischen den Längsbalken angeordnet ist und die Spulenwicklung bzw. die Spulenwicklungen so angeordnet sind, dass sie die Längsbalken und den Ferritkern mindestens auf einem Teilabschnitt von deren Länge umfassen, und mit elektrischen Anschlusselementen.The The invention relates to a miniature inductive component for SMD mounting with a one-piece ferrite core, which in at least one coil winding carrying winding carrier made of plastic, which is substantially rectangular, from two longitudinal beams and two crossbars constructed frame is formed, wherein the Ferrite core between the longitudinal beams is arranged and the coil winding or the coil windings are arranged so that they are the longitudinal beams and the ferrite core at least on a section of their length, and with electrical Connecting elements.
Ein
derartiges Bauelement ist bekannt und beispielsweise in
Der Erfindung liegt die Aufgabe zugrunde, ein induktives Bauelement mit den eingangs und im Oberbegriff des Schutzanspruchs 1 aufgeführten Merkmalen so auszubilden, dass seine Herstellung und Montage möglichst wenig Aufwand erfordern.Of the Invention is based on the object, an inductive component with the beginning and in the preamble of claim 1 protection features to train so that its production and installation as possible require little effort.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Schutzanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.The solution This object is achieved according to the invention with the features of characterizing part of the protection claim 1. Advantageous developments of the invention are in the dependent claims described.
Ein Grundgedanke der Erfindung besteht darin, in den beiden Querbalken des den Wicklungsträger bildenden Rahmens Durchtrittsöffnungen anzuordnen, in welche Metallstäbe oder Metallstreifen so eingesteckt sind, dass sie an beiden Enden aus der Durchtrittsöffnung herausragen. Das an der Oberseite des Bauelements liegende Ende eines solchen Metallstabes oder Metallstreifens ist mit einem Ende einer Spulenwicklung verbunden, während das an der Unterseite des Bauelements liegende Ende des Metallstabes oder Metallstreifens parallel zur Unterseite des Bauelements umgebogen ist und als Anschlusselement für das Bauelement ausgebildet ist. Auf diese Weise ist die Herstellung des Bauelements, die automatisiert erfolgen soll, außerordentlich vereinfacht, indem die Metallstäbe oder Metallstreifen automatisch vorgefertigt und dann ebenfalls automatisch in die vorgefertigten Wicklungsträger eingesetzt werden können.One The basic idea of the invention resides in the two transversal bars of the winding carrier forming frame passages to arrange in which metal rods or metal strips are inserted so that they are at both ends from the passage opening protrude. The end located at the top of the device of such a metal bar or metal strip is connected to one end of a Coil winding connected while the lying at the bottom of the component end of the metal rod or metal strip bent parallel to the bottom of the device is and as a connection element for the component is formed. This is the production of the device to be automated, extremely simplified by the metal rods or metal strips automatically prefabricated and then likewise can be automatically inserted into the prefabricated winding support.
Im Folgenden wird anhand der beigefügten Zeichnungen ein Ausführungsbeispiel für ein induktives Miniatur-Bauelement nach der Erfindung näher erläutert.in the The following will become apparent from the attached drawings an embodiment for a Inductive miniature device according to the invention explained in more detail.
