Description
Kontaktfeder. Die Erfindung betrifft eine Kontaktfeder, wie sie für elektrische Apparate, besonders elektrische Schaltapparate, Verwendung findet.
Bei .den bisherigen Kontaktfedern, nament lich für grössere Stromstärken, tritt der Übel stand auf, dass die Kontaktflächen der Kon taktfedern nur mit einem geringen Teil ihrer Gesamtfl#iiche die Gegenkontaktflächen, z. B. die Kontaktfläic.hen der .Schaltmesser, berüh ren, und dadurch leicht eine schädliche Er wärmung auftritt.
Auch wird diese schlechte Berührung durch den beim Ausschalten er zeugten Funken, welcher das Material schmelzen kann, noch verstärkt, da unter Um ständen die entstehenden Schmelzperlchen die Kontaktfedern auseinanderdrücken und eine ,nute Berührung .mit den Gegenkontaktflächen verhindern. Um diesem Übelstand abzuhelfen, sind die Kontaktfedern gelegentlich mit so genannten Funkenziehern ausgestattet wor den.
Diese Vorrichtungen machen aber die Kontaktfedern kompliziert und tragen :auch nicht zur Stromübertragung bei.- Die vorliegende Erfindung beseitigt die erwähnten Übelstände dadurch, dass .die Kon taktfeder mehrere inein:
andergeschobene Ein- zelfedern,aufweist, .die voneinander unabhän gig bewegliche metallene Kontaktflächen be sitzen, welch letztere mit dem Gegenkontakt nacheinander in und ausser Eingriff kommen. Die der Erfindung gemäss. gebaute Kon taktfederbietet den grossen Vorteil, dass selbst bei hohen Stromstärken verhältnismässig dünne Federbleche Verwendung finden kön nen, deren Verarbeitung und Formgebung viel .genauer ausgeführt wenden kann als die jenige bei starken Federblechen.
Ein weiterer Vorteil besteht darin, :dass jede der Einzel federn über Kontaktfeder für sich federn und mit,dem .Gegenkontakt in Berührung kommen kann.
Durch diese Anordnung wird eine viel bessere Kontaktgebung gewährleistet, da ,durch das Versagen eines KontaktfläcIien- p,aares nur ein geringer Teil der Gesa-mtkon- taktoberfläche ausgeschaltet wird, während bei einer einteiligen Feder durch einen Fremd körper die ganze Kontaktfläche unwirksam wird. Die äussere Kontaktfeder dient bei die ser Anordnung .als Funkenzieher.
Auf der Zeichnung sind vier Ausfüh rungsformen rdes Erfindungsgegenstandes bei spielsweise dargestellt. Fi.g. 1 bis zeigen je eine Vorder- und Seitenansicht der vier Ausführungsformen.
Bei der Ausführungsform nach Fig. 1 be steht die Kontaktfeder aus zwei gebogenen Einzelfedern a und b, die ineinander gescho ben sind. Die .aussenliegende Kontaktfeder hat kurze, nach einwärts gebogene Sehenkel, die innenliegende Kontaktfeder b längere, nach einwärts gebogene Schenkel.
Diese Snlienl@el dienen als Kontaktflticheii. Die Kontakt federn a und b werden in bekannter Weise in ein geschlitztes Anschlussstüek c einge lötet oder festgeschraubt. In diesem Kontakt stück c werden die Zuleitungsdrähte durch eine Klemmsühraube <I>d</I> in der Bohrung f fest geklemmt. Der Ans@chluss, der Zuleitungs drähte kann auch auf andere bekannte Weise erfolgen.
Bei der Ausführungsform nach Fig. 2 sind drei Einzelfedern<I>a, b,</I> g ineinanderge- schoben. Ausserdem ist eine Unterteilung in Gruppen in der Breite der Kontaktfeder vor gesehen, derart, da.ss die Kontaktfeder ge schlitzt ist, oder dass mehrere Gruppen von ineinandergeschobenen Einzelfedern neben einander in dem Schlitz des Anschltissstüclzes c befestigt sind.
Fig. 3 zeigt eine Kontaktfeder mit drei Gruppen von drei ineinundergeschobenen Ein- ze.lfedern a1, b', <B><I>9</I></B> ', welche nur in der Form der Kontaktllä;clien von der Ausführungsform nach Fig. 1 und 2 ail,-uvuiclien.
Fig. d zeigt eine Kontaktfeder mit vier Gruppen von vif#r ineinandergeschobenen Ein zelfedern a2, b2, c# I', la=, ähnlich der Fig. 1 bis 3, jedoch ist hier die Anördnung so vor gesehen, dass diu Einzelfedern aus verhält nismässig dünnen Blechen lierge:tellt sind und je nach der Lage mehrfach abgekröpft sind.
Durch diese Anordnung wird eine be sonders sanfte und doch gute Federuno, und ein guter Kontakt bezweckt. Die Form der Einzelfedern kann aueli noch eine andere sein.
Contact spring. The invention relates to a contact spring of the type used for electrical apparatus, especially electrical switching apparatus.
In the case of the previous contact springs, namely for larger currents, the problem arises that the contact surfaces of the contact springs only meet the mating contact surfaces with a small part of their total area, e.g. B. the Kontaktfläic.hen the .Schaltmesser, touch Ren, and thus easily a harmful heating occurs.
This bad contact is also intensified by the spark generated when switching off, which can melt the material, as the resulting melt beads may push the contact springs apart and prevent a slight contact with the mating contact surfaces. In order to remedy this inconvenience, the contact springs are occasionally equipped with so-called spark pullers.
However, these devices make the contact springs complicated and also do not contribute to the transmission of electricity. The present invention eliminates the drawbacks mentioned by the fact that the contact spring contains several in one:
single springs pushed on the other, .the independently movable metal contact surfaces, which the latter come into and out of engagement with the mating contact one after the other. According to the invention. Built contact spring offers the great advantage that even with high currents, relatively thin spring steel sheets can be used, the processing and shaping of which can be carried out much more precisely than the one with strong spring steel sheets.
Another advantage is that: each of the individual springs springs individually via contact springs and can come into contact with the counter contact.
This arrangement ensures a much better contact, because the failure of a contact surface only switches off a small part of the total contact surface, while with a one-piece spring the entire contact surface becomes ineffective due to a foreign body. In this arrangement, the outer contact spring serves as a spark puller.
In the drawing, there are four embodiments of the subject matter of the invention, for example. Fi.g. 1 through 1 each show a front and side view of the four embodiments.
In the embodiment of Fig. 1 be the contact spring consists of two curved individual springs a and b, which are ben scho into each other. The external contact spring has short, inwardly curved legs, the inner contact spring b has longer, inwardly curved legs.
These lines serve as contact flticheii. The contact springs a and b are soldered or screwed into a slotted connector c in a known manner. In this contact piece c, the lead wires are firmly clamped in the bore f by means of a clamping screw hood <I> d </I>. The connection, the supply wires can also be made in other known ways.
In the embodiment according to FIG. 2, three individual springs <I> a, b, </I> g are pushed into one another. In addition, a subdivision into groups across the width of the contact spring is provided such that the contact spring is slotted or that several groups of individual springs pushed into one another are fastened next to one another in the slot of the connection piece c.
3 shows a contact spring with three groups of three nested single springs a1, b ', <B><I>9</I> </B>', which are only available in the form of contact balls from the Embodiment according to FIGS. 1 and 2 ail, -uvuiclien.
Fig. D shows a contact spring with four groups of vif # r nested single springs a2, b2, c # I ', la =, similar to FIGS. 1 to 3, but here the arrangement is seen in front of that that the individual springs from behaving properly thin metal sheets are lierge: tellt and are bent several times depending on the position.
This arrangement is intended to be particularly gentle and yet good spring uno and good contact. The shape of the individual springs can also be different.
