Description
Die Erfindung betnfft eine Halterung für eine elektrische Spule mit aus magnetischem Material bestehenden E-Kemhälften, insbesondere EC-Kernhälften mit runden Mittelschenkeln und mit einem Spulenkörper mit hohlzylindrischem Vickelträger, der auf diese Mittelschenkel aufgeschoben ist und an seinen Stirnseiten einstückig angeformte Lötfahnenleisten trägt.The invention relates to a holder for an electrical coil with E-core halves made of magnetic material, in particular EC core halves with round central legs and with a coil body with a hollow cylindrical Vickel carrier, which is pushed onto these central legs and carries solder tabs integrally formed on its end faces.
Bei elektrischen Spulen mit kleinen E-Kernen mit geringem Gewicht, wie sie beispielsweise im Siemens-Datenbuch 1975/76 "Weichmagnetisches Siferrit- und Sirufer-Material" Seiten 372-378 beschrieben sind, wird zur Halterung der aus E-Kernhälften, Spulenkörper und Wicklung bestehenden Spuleneinheit üblicherweise nur ein federnder Bügel verwendet. Für elektrische Spulen mit großen und gewichtigen E-Kernen sind häufig Blattfedern o.ä. vorgesehen, mittels denen die beiden Kernhälften zusammengedrückt werden. Dies kann jedoch zu einer negativen Beeinflussung des Luftspaltes und damit zu unerwünschten Änderungen der elektrischen und magnetischen Werte Für Spulen mit EC-Kernen mit rundem Mittelschenkel ist eine Halterung bekannt, die aus einem U-förmigen Blechrahmen, einem Querträger, der in den Rahmen einschnappt, und einer Ausgleichsfeder besteht. Diese Halterung ist sehr aufwendig und mechanisch äußerst instabil.For electrical coils with small E-cores with low weight, as described for example in the Siemens data book 1975/76 "Soft magnetic siferrite and Sirufer material" pages 372-378, is used to hold the E-core halves, bobbin and winding existing coil unit usually used only a resilient bracket. For electrical coils with large and heavy E-cores, leaf springs or the like are often used. provided by means of which the two core halves are pressed together. However, this can have a negative influence on the air gap and thus undesirable changes in the electrical and magnetic values For coils with EC cores with a round middle leg, a holder is known which consists of a U-shaped sheet metal frame, a cross member that snaps into the frame, and a compensating spring. This bracket is very complex and mechanically extremely unstable.
Der vorliegenden Erfindungliegt die Aufgabe zugrunde, eine Halterung für eine elektrische Spule der eingangs genannten Art zu schaffen, die einfach gestaltet ist, sich durch eine hohe Schüttelfestigkeit auszeichnet und zudem leicht montierbar ist.The present invention has for its object to provide a holder for an electrical coil of the type mentioned, which is simple in design, is characterized by a high resistance to shaking and is also easy to assemble.
Zur Lösung dieser Aufgabe sieht die Erfindungbei einer Halterung der eingangs genannten Art Schraubbolzen vor, die mit ihren einen Enden mittel- oder unmittelbar gegen eine Außenmantelfläche einer ersten E-Kernhälfte anliegen und mit ihren mit Schraubgewinden ausgebildeten anderen Enden durch Bohrungen eines streifenförmigen Elements geführt und mit diesem verschraubt sind, wobei das streifenförmige Element gegen eine zur genannten Außenmantelfläche parallele Außenmantelfläche der zweiten E-Kernhälfte anliegt.To achieve this object, the invention provides for a holder of the type mentioned screw bolts, which abut one end directly or indirectly against an outer surface of a first E-core half and with their other ends formed with screw threads through bores of a strip-shaped element and with are screwed, the strip-shaped element abutting against an outer lateral surface of the second E-core half parallel to said outer lateral surface.
Zwischen den abgewinkelten Enden der Schraubbolzen und der benachbarten Außenmantelfläche der ersten E-Kernhälfte kann dabei ein weiteres streifenförmiges Element mit Bohrungen angeordnet sein, durch welche die Schraubbolzen geführt sind.A further strip-shaped element with bores through which the screw bolts are guided can be arranged between the angled ends of the screw bolts and the adjacent outer lateral surface of the first E core half.
Eine sichere Halterung ist auch gewährleistet, wenn anstelle dieses zweiten streifeniörmigen Elements die Schraubbolzen durch einen U-förmigen Bügel ersetzt sind, dessen freie Enden gleichfalls Schraubgewinde aufweisen und dessen zueinander parallele Teile in den Nuten der E-Kernhälften geführt sind.A secure mounting is also ensured if, instead of this second strip-shaped element, the screw bolts are replaced by a U-shaped bracket, whose free ends also have screw threads and whose parallel parts are guided in the grooves of the E core halves.
Diese Halterung ist so gestaltet, daß die beiden E-Kernhälften nicht mittig, sondern außen zusammengedrückt werden. Die Befestigung dieser elektrischen Spule auf einer Schaltungsplatine erfolgt durch die.Schraubbolzen bzw. Drahtbügel, deren mit Schraubgewinden ausgebildeten Enden durch Durchbrechungen der Schaltungsplatine geführt und mit dieser verschraubt werden. Die Lotanschlüsse des Spulenkörpers sind dabei in die Leiterplatte gesteckt und dort verlötet oder weisen um 180° nach oben und sind mittels angelöteter Drähte oder Steckanschlüsse verschaltet.This holder is designed so that the two E-core halves are not pressed together in the middle, but on the outside. This electrical coil is fastened to a circuit board by means of the screw bolts or wire clips, the ends of which with screw threads are guided through openings in the circuit board and screwed to the latter. The solder connections of the coil former are plugged into the printed circuit board and soldered there or point upwards by 180 ° and are connected by means of soldered wires or plug connections.
