Description

Belais-Kbntaktfeder mit flacher FederkennlinieBelais contact spring with flat spring characteristics

Die Erfindung betrifft eine Relais-Kbntaktfeder mit flacher Kennlinie·The invention relates to a relay contact spring flat curve

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-Köntaktfeder mit besonders flacher Kennlinie.In those cases where the armature of a small relay The switching force exerted is relatively low, but on the other hand a particularly high sensitivity, combined with reliable switching is required, a relay contact spring is required with a particularly flat characteristic.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Maßnahme anzugeben, mittels derer es gelingt, einer Eelais-Köntaktfeder eine flache Federkennlinie zu verleihen, die noch dazu gewährleistet, daß nach erfolgtem Schließen des Kontaktes ein die Eontaktgabe sichernder Überhub auch bei geringem Erregerstrom durchgeführt werden kann·The invention is based on the object of specifying a simple measure by means of which it is possible to achieve a To give Eelais-Konntaktfeder a flat spring characteristic, which also ensures that after Closing the contact, an overstroke ensuring the contact is also carried out with a low excitation current can be·

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

Auch der übrige Teil der Belais-Kbntaktfeder kann durch Ausnehmungen so geschwächt werden, daß die Auslenkung während des Kbntakthubes mit geringer Mkerkraft möglich ist.The rest of the Belais contact spring can also pass through Recesses are weakened so that the deflection during the Kbntakthubes is possible with little Mkerkraft is.

Gem. 3Hg. 1 hat die aus einer Platine gestanzte Relais-Kontaktfeder 1 im Bereich des Eontaktnietes 2 eine Ausnehmung 3, die so groß ist, daß dort nur noch ein schmaler Eahmen 4 verbleibt.According to 3Hg. 1 has the punched out of a circuit board Relay contact spring 1 in the area of the Eontaktnietes 2 has a recess 3 which is so large that there only a narrow frame 4 remains.

An den Quersteg 5 greift der nicht dargestellte Betätigungskamm in Richtung der Kraft P (siehe Fig. 2 - 4) an. Dadurch wird die Relais-Kantaktfeder 1 mit ihrem Eontaktniet 2 an den Gegenkontakt 6 gedrückt.The actuating comb (not shown) engages the transverse web 5 in the direction of the force P (see FIG Fig. 2 - 4). As a result, the relay square spring 1 with its contact rivet 2 is against the mating contact 6 pressed.

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.According to FIG. 2 the contact is still open, according to FIG. 3 it is just closed and according to FIG. 4 it is switched through. In this state, the frame 4 is bent. This rebound with little increase in strength results in the desired spring characteristics.
