Abstract

A mounting for a moving iron meter carrying. The indicator axle bearing and the field coil body is designed for economical coil body and mounting using a coil body material whose elastic properties enables simple calculation of the most suitable shape. On the side of the mounting nearest the field coil are projections into which fit latches on th coil body. Lugs on the side of the coil body remote from the mounting enable a screen top to be fitted over the coil.

Description

Die Erfindung bezieht sich auf einen Systeaträger fürThe invention relates to a system support for

Dreheisenießwerke zur Aufnahme der Lager für die Zeigerachse und des Spulenkörpers für die Feldspule.Moving iron casting works to accommodate the bearings for the pointer axis and the Bobbin for the field coil.

Bisher wurden die Systemträger von derartigen Meßwerken vorwiegend als Druckgußteil ausgeführt, an das durch zahlreiche kostenaufwendige Arbeitsgänge der bewickelte Spulenkörper ait Schraubverbindungen befestigt werden mußte. Es sind auch schon Lösungen bekannt (08 23 56 114, G01R, 5/14), bei denen der Systeitreger ein einheitliches Kunststoffspritzteil ist.So far, the system carriers of such measuring units have predominantly been executed as a die-cast part, due to numerous costly operations the wound bobbin had to be fastened with screw connections. There are solutions already known (08 23 56 114, G01R, 5/14) in which the system exciter is a uniform plastic injection-molded part.

Aufgabe der Erfindung ist es, einen Systemträger der eingangs genannten Art zu schaffen, bei dem eine wirtschaftlichere Montage des Spulenkörpers möglich ist. Die lauf gabe wird erfindungsgemäß durch die im Anspruch 1 angeführten Merkmale gelöst.The object of the invention is to provide a system carrier of the type mentioned at the beginning To create a way in which a more economical assembly of the coil body is possible is. The running task is according to the invention by the features listed in claim 1 solved.

Die efindungsgemäße Befestigung des Spulenkörpers bietet den Vorteil, daß zur Montage des Meßwerkes keinerlei Schraubverbindungen erforderlich sind. Ein weiterer Vorteil liegt darin, daß zur Herstellung eines Spulenkörpere Kunststoff verwendet werden kann, dessen elastische Eigenschaften der Forderung nach einfacher und paßgenauer Formgebung Rechnung tragen.The fastening of the bobbin according to the invention offers the advantage that no screw connections are required to assemble the measuring mechanism. A Another advantage is that the manufacture of a coil body is made of plastic can be used, its elastic properties of the requirement for simpler and precisely fitting shape.

anhand einer Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Systemträgers erläutert.based on a drawing is an embodiment of the invention System support explained.

Die Figur zeigt in Explosionsdarstellung ein aus fünfzehn Einzelteilen bestehendes funktionsfähiges Dreheisenmeßwerk.The figure shows an exploded view of one of fifteen individual parts existing functional moving iron measuring mechanism.

Ein Systeiträger 1 trägt alle Komponenten des eigentlichen Meßwertes Die Dreheisenanordnung umfaßt ein bewegliches Eisen 15, das an einer mit Spitzen versehenen Achse 16 befestigt ist. Am oberen Teil der Achse 16 sind ein Zeiger 14 und eine Spiralfeder 13 montiert. Die Achsspitzen sind in zwei Lagerelementen 7 drehbar gelagert, die am Systemträger achsmittig zur Mittelachse 17 angeordnet sind.A system carrier 1 carries all components of the actual measured value The moving iron assembly includes a movable iron 15, which is tipped on one provided axle 16 is attached. A pointer 14 is located on the upper part of the axle 16 and a coil spring 13 is mounted. The axis tips are in two bearing elements 7 rotatably mounted, which are arranged on the system carrier axially to the central axis 17.

Das obere Lagerelement 7 befindet sich in einem brückenförmigen 8teg, der gleichzeitig den mit einem Federauge 6 versehenen Nullstellhebel 8 trägt. In Höhe der Vorsprünge 3 sind um die Mittelachse des Trägers herum nicht bezeichnete Ausnehmungen eingelassen, in die ein frei drehbares Justiereisen 9 drehbar eingepaßt und mittels einer Blattfeder gehalten ist.The upper bearing element 7 is located in a bridge-shaped 8teg, which at the same time carries the zero lever 8 provided with a spring eye 6. In The height of the projections 3 are not designated around the central axis of the carrier Recesses let into which a freely rotatable adjusting iron 9 is rotatably fitted and is held by means of a leaf spring.

An das in der geschilderten Reihenfolge zusammengebaute Meßwerk wird von unten her der bewickelte Spulenkörper 2 aufgedrückt. Dabei greifen seine Rastnasen 4 in an entsprechender Stelle am 15ystemträger angeordnete Vorsprünge.To the measuring mechanism assembled in the order described the wound bobbin 2 is pressed on from below. Its locking lugs engage 4 in projections arranged at the corresponding point on the system carrier.

Durch einen Tropfen Lack auf die Schnappverbindung kann der Spulenkörper noch zusätzlich gesichert werden.With a drop of lacquer on the snap connection, the coil body additionally secured.

Der Spulenkörper 2 besitzt seitlich zwei Ausnehmungen 19, in die eine Anschlußplatte 11 eingepaßt ist; sie dient als Lötstiltze für den Spulenanschluß. Am Boden des Spulenkörpers sind Zapfen 18 angeformt, auf die ein über den Spulenkörper gestülpter Abschirmtopf 12 aufgedrückt und durch Verschweißen der Zapfenenden gesichert ist.The bobbin 2 has two recesses 19 on the side, into which one Terminal plate 11 is fitted; it serves as a soldering pad for the coil connection. At the bottom of the bobbin pins 18 are formed, on which one over the bobbin Everted shielding pot 12 pressed on and secured by welding the pin ends is.
