Description

Es ist bekannt, Kontaktfedern so auszubilden, daß der Abreißfunken beim Unterbrechen des Kontaktes von den eigentlichen Kontaktstellen an Punkte wegverlegt wird, wo eine Verbrennung für die weitere Kontaktgebung unschädlich ist. Derartige Kontaktfedern werden im besonderen verwendet bei Eisenbahnsicherungseinrichtungen, z. B, als Steuerkontakte bei Signal- und Weichenantrieben. Man hat hierbei auf die vorhandenen Kontaktfedern neue Federn aufgeschoben, die mit zwei Kontaktstellen für die Aufnahme des Abreißfunkens versehen sind. Die vorliegende Erfindung beruht nun darauf, daß es zweckmäßig ist, die Kontaktfeder für den Abreißfunken genau so auszubilden wie die dauernd stromführende. Diese Feder hat zwei Kontaktflächen, um eine möglichst große Fläche für die Stromführung zu erhalten. Der Abreißfunken wird jedoch immer nur an einer Stelle entstehen; zum mindesten wird sich allmählich eine herausbilden, die regelmäßig den Abreißfunken aufnimmt. Deshalb wird gemäß der Erfindung für den Abreißfunken nur eine möglichst schmale Stelle vorgesehen, was noch den besonderen Vorzug hat, daß nun die einander benachbarten Kontakte eine größere Entfernung voneinander besitzen, so daß die zwischen ihnen auftretende Funkenstrecke vergrößert wird.It is known to design contact springs so that the tear-off spark when interrupted of the contact is moved away from the actual contact points to points where there is a burn for further contact is harmless. Such contact springs are used in particular Railway safety devices, e.g. B, as control contacts for signal and turnout drives. New springs have been pushed onto the existing contact springs, with two contact points for the recording the tear-off spark are provided. The present invention is based on the fact that it it is useful to design the contact spring for the tear-off spark exactly as the continuously live. This spring has two contact surfaces in order to be as large as possible Obtain surface for the current conduction. However, the tear-off spark is only ever at one Place arise; at least one will gradually develop that is regular picks up the tear-off spark. Therefore, according to the invention for the tear-off spark only as narrow a point as possible, which has the special advantage of that now the adjacent contacts are at a greater distance from each other, so that the spark gap occurring between them is increased.

Der Erfindungsgegenstand ist in den Abbildungen näher erläutert.The subject of the invention is in the illustrations explained in more detail.

Abb. ι zeigt den Aufriß der Feder,Fig. Ι shows the elevation of the spring,

Abb. 2 den Grundriß zweier benachbarter Federn.Fig. 2 shows the plan of two adjacent springs.

Die Feder ι trägt den Hauptkontakt, der mit seinen beiden Flächen 2 und 4 bei Kontaktschluß an die Oberfläche der Kontaktwalze 5 zu liegen kommt. Die Feder 6 trägt den Kontakt 7, der mit seiner Spitze 3 bei Entfernung der Walze von den Kontaktfedern den Abreißfunken aufnimmt. Diese an der Walze anliegende Spitze 3 des Kontaktes 7 ist nun gemäß der Erfindung schmaler ausgeführt als die Breite des Kontaktes 2, so daß die Funkenstrecke α zwischen den beiden benachbarten Kontakten 7 und 8 vergrößert wird.The spring ι carries the main contact, which comes to rest with its two surfaces 2 and 4 on the surface of the contact roller 5 when the contact is made. The spring 6 carries the contact 7, which with its tip 3 picks up the tear-off sparks when the roller is removed from the contact springs. According to the invention, this tip 3 of the contact 7 resting against the roller is made narrower than the width of the contact 2, so that the spark gap α between the two adjacent contacts 7 and 8 is increased.

Claims (1)

Patentanspruch:Claim: Kontaktvorrichtung, im besonderen an Weichen- und Signalantrieben, wobei jeder Kontakt als Doppelkontakt ausgebildet ist, derart, daß der eine Kontakt den Strom führt, während der andere Kontakt den Abreißfunken aufnimmt, dadurch gekennzeichnet, daß die den Abreißfunken, aufnehmende Feder (7) an der Kontakt gebenden Stelle (3) schmaler ausgeführt ist als der Hauptkontakt (2).Contact device, in particular on turnout and signal drives, each Contact is designed as a double contact, in such a way that one contact carries the current leads, while the other contact picks up the tear-off spark, characterized in that that the tear-off spark receiving spring (7) on the contact Point (3) is made narrower than the main contact (2).
