Abstract

The invention relates to a relay contact spring with a flat characteristic. In cases in which the switching force exercised by the armature of a small relay is relatively small, but, on the other hand, a particularly high responsiveness, in conjunction with reliable switch operation, is required, a relay contact spring with a particularly flat characteristic is required. The invention is based on the object of specifying a simple measure by means of which a relay contact spring can be provided with a flat spring characteristic which also ensures that, after the contact has completed closing, a geometric lock securing the closure of the contact can be implemented even with a small exciter current. According to the invention this object is achieved by means of a cut-out, arranged in the region of the contact rivet and designed such that only a narrow frame remains there on the upper lateral web of which the point of application of the operating force P is located. <IMAGE>

Description

Die Erfindung betrifft eine Relais-Kontaktfeder mit flacher Kennlinie.The invention relates to a relay contact spring with a flat characteristic.

In den Fällen, in denen die von dem Anker eines Kleinrelais ausgeübte Schaltkraft verhältnismäßig gering ist, andererseits jedoch eine besonders hohe Ansprechempfindlichkeit, verbunden mit sicherem Durchschalten erforderlich ist, benötigt man eine Relais-Kontaktfeder mit besonders flacher KennlinieIn cases in which the switching force exerted by the armature of a small relay is relatively low, but on the other hand a particularly high sensitivity, combined with reliable switching, is required, a relay contact spring with a particularly flat characteristic is required

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Maßnahme anzugeben, mittels derer es gelingt, einer Relais-Kontaktfeder eine flache Federkennlinie zu verleihen, die noch dazu gewährleistet, daß nach erfolgtem Schließen des Kontaktes ein die Kontaktgabe sichernder Überhub auch bei geringem Erregerstrom durchgeführt werden kann.The invention has for its object to provide a simple measure by means of which it is possible to give a relay contact spring a flat spring characteristic, which also ensures that after the contact has been closed, an over-stroke securing the contact can be carried out even with a low excitation current .

Erfindungsgemäß wird diese Aufgabe durch eine im Bereich des Kontaktnietes angeordnete und so ausgebildete Ausnehmung erreicht, daß dort nur ein schmaler Rahmen verbleibt, an dessen oberen Quersteg der Angriff der Betätigungskraft P liegt.According to the invention, this object is achieved by a recess arranged in the region of the contact rivet and designed in such a way that only a narrow frame remains there, on the upper transverse web of which the actuation force P is applied.

Auch der übrige Teil der Relais-Kontaktfeder kann durch Ausnehmungen so geschwächt werden, daß die Auslenkung während des Kontakthubes mit geringer Ankerkraft möglich ist.The remaining part of the relay contact spring can also be weakened by recesses so that the deflection during the contact stroke is possible with a low armature force.

In der Zeichnung ist ein Ausführungsbeispiel einer erfindungsgemäßen Relais-Kontaktfeder dargestellt, anhand dessen die Erfindung im folgenden näher erläutert sei. Es zeigen:

  • Fig. 1 die Vorderansicht eines Ausführungsbeispieles einer erfindungsgemäßen Relais-Kontaktfeder und
  • Fig. 2 - 4 die schematische Seitenansicht der Relais-kontaktfeder mit Gegenkontakt in verschiedenen Phasen der Betätigung.
In the drawing, an embodiment is one Relay contact spring according to the invention shown, based on which the invention will be explained in more detail below. Show it:
  • Fig. 1 is a front view of an embodiment of a relay contact spring according to the invention and
  • Fig. 2-4 the schematic side view of the relay contact spring with mating contact in different phases of actuation.

Gem. Fig. 1 hat die aus einer Platine gestanzte Relais-Kontaktfeder 1 im Bereich des Kontaktnietes 2 eine Ausnehmung 3, die so groß ist, daß dort nur noch ein schmaler Rahmen 4 verbleibt.1, the relay contact spring 1 stamped from a circuit board has a recess 3 in the area of the contact rivet 2 which is so large that only a narrow frame 4 remains there.

An den Quersteg 5 greift der nicht dargestellte Betätigungskamm in Richtung der Kraft P (siehe Fig. 2 - 4) an. Dadurch wird die Relais-Kontaktfeder 1 mit ihrem Kontaktniet 2 an den Gegenkontakt 6 gedrückt.The actuating comb, not shown, acts on the crosspiece 5 in the direction of the force P (see FIGS. 2-4). As a result, the relay contact spring 1 is pressed with its contact rivet 2 against the counter contact 6.

Gem. Fig. 2 ist der Kontakt noch offen, gem. Fig. 3 ist er gerade geschlossen und gem. Fig. 4 durchgeschaltet. In diesem Zustand ist der Rahmen 4 durchgebogen. Dieses Nachfedern mit geringem Kraftzuwachs-ergibt die gewünschte Federcharakteristik. Liste der Zeichnunaspositionen:

  • 1 Relais-Kontaktfeder
  • 2 Kontaktniet
  • 3 Ausnehmung
  • 4 Rahmen
  • 5 Quersteg
2, the contact is still open, according to Fig. 3 it is just closed and gem. Fig. 4 switched through. In this state, the frame 4 is bent. This resilience with little increase in force results in the desired spring characteristics. List of drawing positions:
  • 1 relay contact spring
  • 2 contact rivet
  • 3 recess
  • 4 frames
  • 5 crossbar
