Description

Die Anker von Relais, Meßinstrumenten u. dgl. werden häufig mit Hilfe einer eingespannten Torsionsfeder gelagert. Wenn die Konstruktion des Relais oder des Meßinstruments verhältnismäßig geringe Rückstellkräfte verlangt, so machen sich die Einflüsse von Biegungsmomenten auf der Feder bemerkbar, die beispielsweise von den Polen der magnetischen Kreise ausgeübt werden. Bei den bekannten Anordnungen dieser Art ist die Torsionsfeder bandförmig ausgebildet, und ihr Querschnitt stellt ein Rechteck dar, dessen längere Seite zwischen den beiden Blechen eingespannt ist, die den Anker bilden. Die magnetischen Kräfte des magnetischen Kreises greifen nun in der Regel senkrecht zum Anker an und beanspruchen die Torsionsfeder in Richtung der kürzeren Seite des Rechteckquerschnitts. Der Einfluß dieser Kräfte wird um so größer, je kleiner die Rückstellkraft der Torsionsfeder ist.The anchors of relays, measuring instruments and the like are often with the help mounted on a clamped torsion spring. If the design of the relay or of the measuring instrument requires relatively low restoring forces, so make yourself the influences of bending moments on the spring are noticeable, for example from applied to the poles of the magnetic circuits. In the known arrangements of this type, the torsion spring is designed in the form of a band, and its cross-section represents represents a rectangle, the longer side of which is clamped between the two metal sheets, which form the anchor. The magnetic forces of the magnetic circuit now take effect usually perpendicular to the armature and stress the torsion spring in the direction the shorter side of the rectangular cross-section. The influence of these forces is all the more larger, the smaller the restoring force of the torsion spring is.

Gemäß der Erfindung wird diese unerwünschte Beanspruchung der Torsionsfeder durch Biegungsmomente dadurch vermindert, daß die längere Seite des rechteckigen Federquerschnitts in Richtung der die Feder auf Biegung beanspruchenden Kraft liegt.According to the invention, this undesirable stress on the torsion spring becomes reduced by bending moments in that the longer side of the rectangular Spring cross-section lies in the direction of the spring stressing the bending force.

Die Fig. i stellt den Ankeraufbau eines gepolten Relais üblicher Bauart dar, während die Fig. 2 die Federlagerung eines solchen Ankers nach der Erfindung zeigt.Fig. I shows the armature structure of a polarized relay of conventional design represents, while Fig. 2 shows the spring mounting of such an anchor according to the invention shows.

Die Pole i und 2 (Fig. i) des magnetischen Kreises des gepolten Relais beeinflussen den aus zwei Blechen 3 und 4 zusammengesetzten Anker.Poles i and 2 (Fig. I) of the magnetic circuit of the polarized relay affect the anchor, which is composed of two sheets 3 and 4.

Zwischen den Blechen 3 und 4 ist eine Torsionsfeder 5 mit rechteckigem Querschnitt mit Hilfe der Schrauben 8 und 9 eingespannt. Am anderen Ende des Ankers befinden sich die Kontakte 6 und 7, die in bekannter Weise durch die Pole i und 2 des magnetischen Kreises an die nicht dargestellten Gegenkontakte des gepolten Relais umgelegt werden.Between the sheets 3 and 4 is a torsion spring 5 with a rectangular Cross-section clamped with the help of screws 8 and 9. At the other end of the anchor are the contacts 6 and 7, which in a known manner by the poles i and 2 of the magnetic circuit to the mating contacts, not shown, of the polarized Relays are switched.

Aus Fig.,i ist ersichtlich, daß die Pole i und -- ein gewisses Biegungsmoment auf die Feder ausüben.From Fig., I it can be seen that the poles i and - exert a certain bending moment on the spring.

Bei der erfindungsgemäßen Anordnung nach Fig. 2 beeinflussen die Pole i-i und 12 in der bekannten Weise den Anker. Dieser besteht aus vier Teilen 13, 14, 15 und 16. Die Teile werden in der Längsrichtung durch Schrauben 1 7 und 18 zusammengehalten und sind in der Querrichtung durch zwei Schrauben i9 und 20 verbunden, mit deren Hilfe die Blattfeder 21 eingespannt wird. Die magnetischen Kräfte können bei einer derartigen Anordnung die Feder 21 nicht auf Biegung beanspruchen, so daß man die Torsionsfeder mit geringerer Rückstellkraft und damit das Relais mit höherer Empfindlichkeit lauen kann.In the arrangement according to the invention according to FIG. 2, the poles influence i-i and 12 the anchor in the known manner. This consists of four parts 13, 14, 15 and 16. The parts are fastened in the longitudinal direction by screws 1 7 and 18 held together and connected in the transverse direction by two screws i9 and 20, with the help of which the leaf spring 21 is clamped. The magnetic forces can In such an arrangement, the spring 21 does not require bending, so that the torsion spring with a lower restoring force and thus the relay with a higher one Sensitivity can be tepid.
