Abstract
Description
Die Erfindung betrifft ein induktives Miniatur-Bauelement für SMD-Montage mit einem einteiligen Ferritkern, dessen Länge größer ist als seine Breite, und mit mindestens einer direkt auf den Ferritkern aufgebrachten Spulenwicklung mit elektrischen Anschlusselementen und mit an beiden Enden des Ferritkerns angeordneten Anschlussflanschen.The The invention relates to a miniature inductive component for SMD mounting with a one-piece ferrite core, whose length is larger as its width, and with at least one directly on the ferrite core applied coil winding with electrical connection elements and with attached at both ends of the ferrite core connecting flanges.
Ein derartiges Bauelement ist an sich bekannt und beispielsweise in WO 2005/052963 beschrieben.One Such a device is known per se and, for example, in WO 2005/052963 described.
Der Erfindung liegt die Aufgabe zugrunde, ein induktives Miniatur-Bauelement mit den eingangs und im Oberbegriff des Schutzanspruchs 1 angegebenen Merkmalen so weiterzubilden, dass die vollautomatisierte Fertigung und die Montage mit möglichst geringem Aufwand durchführbar ist.Of the Invention is based on the object, an inductive miniature device with the At the outset and in the preamble of claim 1 protection features educate so that the fully automated production and the Assembly with the lowest possible Effort feasible is.
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.
Bei dem obenerwähnten bekannten induktiven Bauelement sind die an den Enden des Ferritkerns angeordneten Flansche als auf den Ferritkern aufsteckbares und mit ihm fest verbundenes Kunststoffteil ausgebildet. Hierbei sind bei der bekannten Ausführungsform durch die als Kunststoffteil ausgebildeten Flansche von der Oberseite zur Unterseite des Bauelements hindurchgeführte, an beiden Enden austretende Metallstäbe oder Metallstreifen vorgesehen, wobei jeweils das an der Oberseite des Bauelements liegende Ende mit einem Wicklungsende einer Spulenwicklung verbunden ist, während das an der Unterseite liegende, parallel zur Unterseite des Bauelements umgebogene Ende als Anschlusselement ausgebildet ist.at the above mentioned known inductive component are those at the ends of the ferrite core arranged flanges as attachable to the ferrite core and with trained him plastic part. Here are at the known embodiment by the plastic parts formed as flanges from the top led to the bottom of the device, exiting at both ends metal rods or metal strips provided, each at the top the component lying end with a coil end of a coil winding is connected while the underlying, parallel to the bottom of the device bent end is designed as a connection element.
Der Grundgedanke der Erfindung besteht nun darin, die am Ferritkern angeordneten Anschlussflansche aus Ferritmaterial bestehen zu lassen und jeweils einstückig an den Ferritkern bei dessen Herstellung anzuformen. In den so aus Ferritmaterial bestehenden Anschlussflanschen sind jeweils in Richtung von der Oberseite zur Unterseite des Bauelements verlaufende Durchtrittsöffnungen angeordnet, in welche jeweils ein an beiden Enden aus dem Ferritkern austretender Metallstab oder Metallstreifen eingesteckt ist. Das an der Oberseite liegende Ende dieser Metallstäbe oder Metallstreifen ist jeweils mit einem Ende einer Spulenwicklung verbunden, während das an der Unterseite liegende, parallel zur Unterseite des Bauelements umgebogene Ende als Anschlusselement ausgebildet ist.Of the The basic idea of the invention is now that arranged on the ferrite core Connection flanges made of ferrite material and each leave one piece to form on the ferrite core during its production. In the way out Ferrite material existing connection flanges are each in the direction from the top to the bottom of the device extending through openings arranged, in each of which one at both ends of the ferrite core emerging metal rod or metal strip is inserted. The is at the top end of these metal rods or metal strips each connected to one end of a coil winding while the located at the bottom, parallel to the bottom of the device bent end is designed as a connection element.
Es ergibt sich somit eine erhebliche Ersparnis an Aufwand bei der vollautomatisierten Herstellung des Bauelements, indem nach der Herstellung des Ferritkerns kein Aufstecken und Fixieren von eigens herzustellenden Flanschen mehr erforderlich ist.It This results in a considerable saving of effort in the fully automated Production of the device by following the manufacture of the ferrite core no attaching and fixing of specially manufactured flanges more is needed.
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.
