Description

Die Erfindung betrifft eine Halterung für eine elektrische Spule mit aus magnetischem Material, insbesondere Ferrit, bestehenden E-Kernhälften, insbesondere 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 magnetic core, in particular ferrite, existing E-core halves, in particular with round central legs and with a coil body with a hollow cylindrical Vickel carrier, which is pushed onto these central legs and carries integrally molded solder tabs 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 zu einer negativen Beeinflussung des Luftspaltes und damit zu unerwünschten Änderungen der elektrischen und magnetischen Werte der Spule führen.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. This can have a negative influence on the air gap and thus undesirable effects Change the electrical and magnetic values of the coil.

Für Spulen mit EC-Kernen mit rundem Mittelschenkel ist eine Halterung bekannt, die aus einem aufwendigen U-förmigen Blechrahmen, einem Querträger, der in den Rahmen einschnappt, und einer Ausgleichsfeder besteht. Diese Halterung ist nicht nur sehr aufwendig, sondern auch mechanisch instabil.For coils with EC cores with a round middle leg, a holder is known which consists of an elaborate U-shaped sheet metal frame, a cross member that snaps into the frame, and a compensating spring. This bracket is not only very complex, but also mechanically unstable.

Der vorliegenden Erfindungliegt die Aufgabe zugrunde, eine Halterung für eine elektrische Spule der eingangs genannten Art zu schaffen,-die sich, abgesehen von ihrer geringen Aufwendigkeit, vor allem auch durch ihre Schüttelfestigkeit auszeichnet.The present invention has for its object to provide a holder for an electrical coil of the type mentioned, which, apart from its low complexity, is also characterized by its resistance to shaking.

Zur Lösung dieser Aufgabe sieht die Erfindungbei einer Halterung der eingangs genannten Art zwei zueinander parallel ausgerichtete Winkelstücke vor, die mit einem Bereich ihrer einen Schenkel gegen parallele Außenmantelflächen der E-Kernhälften anliegen und mittels Schraubbolzen miteinander verschraubt sind und deren andere Schenkel auf einer Schaltungsplatine befestigbar sind.To achieve this object, the invention provides for a bracket of the type mentioned two mutually parallel angle pieces which rest with a portion of one leg against parallel outer surface surfaces of the E-core halves and are screwed together by means of bolts and the other legs of which can be fastened to a circuit board .

Diese Halterung ist so gestaltet, daß die beiden E-Kernhälften nicht in der Mitte, sondern außen zusammengedrückt werden. Die elektrische Spule wird dabei durch Schrauben mit der Leiter- oder Chassisplatte verbunden, wobei die Lötanschlüsse des Spulenkörpers in die Leiterplatte gesteckt und dort verlötet werden oder um 180° gedreht nach oben weisen und mittels angelöteter Drähte oder Steckanschlüsse verschaltet sind. Die Befestigung der gesamten Spule erfolgt z.B. mittels Zylinderschrauben, die durch Durchgangslöcher in der Leiter- bzw. Chassisplatte und den einen Schenkeln der Winkelstücke der Halterung gesteckt und z.B. mit Sechskantmuttern verschraubt sind. Die Durchgangslöcher der Schenkel der Winkelstücke können auch ein Gewinde zum Eindrehen von Schrauben oder entsprechend geformte Düsen für Zylinder-Blechschrauben mit selbstschneidendem Gewinde aufweisen.This holder is designed so that the two E-core halves are not pressed together in the middle, but on the outside. The electrical coil is connected to the circuit board or chassis plate by screws, the solder connections of the coil former being inserted into the circuit board and soldered there or turned upwards by 180 ° and connected by means of soldered wires or plug connections. The entire coil is fastened, for example, by means of cheese head screws which pass through through holes in the conductor or Chassis plate and one leg of the angle pieces of the bracket are inserted and screwed, for example, with hexagon nuts. The through holes of the legs of the angle pieces can also have a thread for screwing in screws or correspondingly shaped nozzles for cylinder self-tapping screws with self-tapping thread.
