Description

Kernanordnung von Kleintransformatoren, Drosseln o. dgl. Bei Kernen kleineren Ausmaßes ist es zweckmäßig, wenn man von Bolzen u. dgl. zur Halterung des Blechpaketes absehen kann. Es sind deshalb schon Bauarten von Kernen bekanntgeworden, bei denen die aufeinandergeschichteten Kernbleche seitlich durch Blechstreifen mit umgebogenen Längskanten gehalten werden.Core arrangement of small transformers, chokes or the like. With cores On a smaller scale, it is useful if you move from bolts and the like to the bracket of the laminated core can see. There are therefore already known types of cores, in which the stacked core sheets are laterally supported by sheet metal strips bent longitudinal edges are held.

Die Erfindung bezieht sich auf eine derartige K ernanordnung, und zwar bei Kernen, die mit einem Luftspalt versehen sind. Erfindungsgeinäh wird mindestens einer dieser Blechstreifen als Streusteg benutzt. Dadurch wird der Vorteil erzielt, daß die Blechstreifen gleichzeitig neben ihrer Bestimmung zur Halterung der aufeinandergeschiohteten Kernbleche noch eine weitere Funktion ausüben können. Werden die als Streusteg dienenden Blechstreifen noch in der Höhe des Luftspaltes schräg unterteilt und die beiden Teile verschi.eL-bar angeordnet, so kann der Blechstreifen gleichzeitig zur Regelung des Luftspaltes dienen.The invention relates to such a core arrangement, and with cores that are provided with an air gap. Invention is at least one of these sheet metal strips is used as a spreading bar. This has the advantage of that the sheet metal strips at the same time in addition to their determination to hold the one on top of the other Core sheets can also perform another function. Will serve as a spreading path Sheet metal strips are divided diagonally at the height of the air gap and the two Parts arranged differently so that the sheet metal strip can be used for regulation at the same time serve the air gap.

In .den Fig. i und 2 ist die an sieh bekannte Kernanordnung dargestellt. i bezeichnet den Kern, der aus einer Anzahl Blechen zusammengesetzt ist, 2 ein Gehäuse aus sogenannten Schutzblechen zur Aufnahme der Wicklung der Drossel o. dgl. Die Schutzbleche liegen mit ihren irgendwie geformten Enden 3 auf dem Blechpaket an und werden zusammen mit dem Blechpaket seitlich durch Blechstreifen 4. gehalten, deren Längskanten C umgebogen sind.In .den Fig. I and 2, the known core arrangement is shown. i denotes the core, which is composed of a number of metal sheets, 2 a housing from so-called protective sheets to accommodate the winding of the throttle o. The like. The Mudguards rest with their somehow shaped ends 3 on the laminated core and are held together with the laminated core at the side by sheet metal strips 4., whose longitudinal edges C are bent.

In den Fig. 3 bis 3 ist die Kernanordnung nach der Erfindung dargestellt. Danach is: der aus aufeinandergeschichteten Kernblechen bestehende Kern i mit einem Luftspalt 7 versehen und der Blechstreifen in Höbe des Luftspaltes schräg unterteilt.3 to 3, the core assembly according to the invention is shown. Then: the core i consisting of stacked core sheets is provided with an air gap 7 and the sheet metal strip is diagonally divided in height of the air gap.

Wie die Fig.4 und 5 erkennen lassen, ist der Teil 4 so verschiebbar gelagert, daß der Luftspalt mehr oder weniger durch diesen als Streublech dienenden Blechstreifen überbrückt wird. Auch diese beiden Blechstreifenteile können gleichzeitig so ausgebildet sein, daß sie die Schutzbleche 2 halten.As can be seen in FIGS. 4 and 5, the part 4 is displaceable in this way stored that the air gap more or less through this serving as a diffuser Sheet metal strip is bridged. These two sheet metal strip parts can also be used at the same time be designed so that they hold the protective plates 2.

Selbstverständlich muß Vorsorge dafür ge- troffen sein, daß sich dieser Streusteg während des Betriebes nicht verändert, nachdem er einmal eingestellt worden ist. Dazu katiit der verschiebbare Teil in irgendeiner Weise am Paket Jeweils befestigt sein.Of course, care must be dripped for overall that this scattering bar does not change during operation after it has been set once. For this purpose, the movable part can be attached to the package in any way.
