Description

Der Raum, in dem die Kontaktfedern elektrischer Schalter untergebracht werden müssen, ist meist derart beschränkt, daß die notwendige Elastizität der Feder nicht erreicht wird. Man versieht deshalb vielfach die Kontaktfedern mit Hilfsfedern, die den Auflagedruck derselben auf der Schaltwalze erhöhen. Insbesondere benutzt man derartige Einrichtungen bei Walzenschaltern, und zwar so, daß diese Hilfsdruckfedern sich zwischen den Anschlußklemmen und den Kontaktfedern befinden.The room in which the contact springs for electrical switches are housed must be, is usually so limited that the necessary elasticity of the spring is not achieved. The contact springs are therefore often provided with auxiliary springs, which increase the contact pressure of the same on the shift drum. Used in particular one such devices with roller switches, in such a way that these auxiliary compression springs are located between the connection terminals and the contact springs.

Die geringe Elastizität der Kontaktfedern elektrischer Schalter liegt aber auch oft daran, daß durch die Befestigung der Feder an der Anschlußklemme zuviel von der Federlänge verlorengeht. Außerdem wird durch diese Befestigungsmittel oft ein schlechter Stromübergang verursacht.The low elasticity of the contact springs of electrical switches lies but also often the fact that by attaching the spring to the connector too much of the spring length is lost. In addition, these fasteners often caused a bad current transfer.

Um diesen Nachteilen aus dem Wege zu gehen, ist die Kontaktfeder bis zum Anschluß an die Klemmschraube verlängert, so daß sie einen der Sockelaussparung angepaßten Bügel bildet, der mittels des Anschlußklemmwinkels gegen die Wände der Aussparung gedrückt wird. Der Anschlußkontakt selbst besteht aus einem Anschlußwinkel von Eisen, der neben der Anschlußschraube nach bekannter Art rechtwinklig gebogene Lappen zum Festhalten des Anschlußdrahtes besitzt. Nach der Erfindung besitzt der Anschlußklemmbügel noch einen von seinem äußeren Ende abgebogenen Lappen, mit dem er zentrisch durch die Spreiz- und Kontaktdruckfeder greift, wobei dieser Lappen durch einen Anschlag den Ausschlag der Kontaktfeder begrenzt.In order to avoid these disadvantages, the contact spring is up to extended for connection to the clamping screw, so that it is one of the base recess adapted bracket forms, which by means of the terminal bracket against the walls of the Recess is pressed. The connection contact itself consists of a connection bracket of iron, which is bent at right angles next to the connection screw in a known manner Has flaps to hold the connecting wire. According to the invention, the Terminal clip still has a flap bent from its outer end with which it engages centrically through the expansion and contact pressure spring, this lobe the deflection of the contact spring is limited by a stop.

Der durch die Druckfeder greifende, z. B. als Stift ausgebildete Lappen kann auch gelenkig an der Kontaktfeder befestigt sein und den Anschlußkontaktwinkel durchdringen. Als Druckfeder zur Unterstützung der Kontaktfeder wird entweder eine aus Runddraht konisch gewickelte Feder oder eine konische Pufferfeder vorteilhaft benutzt.The reaching through the compression spring, z. B. designed as a pin lobes can also be hinged to the contact spring and the connection contact angle penetrate. As a compression spring to support the contact spring, either a Conically wound spring made of round wire or a conical buffer spring is advantageous used.

Die Abb. i zeigt den Erfindungsgegenstand von der 'Vorderseite und die Abb. 2 von der linken Seite aus gesehen; die Abb.3 zeigt die Anordnung des an der Kontaktfeder befestigten Führungsstiftes der Druckfeder. Die Kontaktfeder i (Abb. i) ist auf der Klemmschraube 2 bis zu dem Kontaktauflageklotz 3 aus einem Stück hergestellt. Sie wird durch den Anschlußwinkel 4 vermittels der Schraube 5 auf dem Sockel 6 festgehalten.Fig. I shows the subject of the invention from the 'front and Fig. 2 seen from the left; Fig.3 shows the arrangement of the the contact spring attached guide pin of the compression spring. The contact spring i (Fig. I) is on the clamping screw 2 up to the contact pad 3 from one Piece made. It is secured by the connection bracket 4 by means of the screw 5 held on the base 6.

Der Anschlußkontaktwinkel4 besitzt seitlich der Anschlußschraube 2 rechtwinklig gebogene Lappen 7 (Abb. i und 2), welche zum Festhalten des Anschlußdrahtes dienen. An dem Anschlußwinkel4 ist außerdem noch der als Stift geformte Lappen 8 abgebogen (Abb. i), der die Kontaktfeder i durchdringt. Dieser Stift 8, welcher der Druckfeder 9 als Führung dient, besitzt an seinem vorderen Ende eine Verdickung io, durch die der Ausschlag der Kontaktfeder i begrenzt wird. Der Stift 8 kann aber auch, wie Abb. 3 zeigt, mit der Kontaktfeder i gelenkig verbunden sein und den Anschlußwinkel4 durchdringen.The connection contact bracket 4 has the connection screw 2 on the side Right-angled lugs 7 (Fig. i and 2), which are used to hold the connecting wire to serve. The tab 8 shaped as a pin is also attached to the connection bracket 4 bent (Fig. i), which penetrates the contact spring i. This pin 8, which one the compression spring 9 serves as a guide, has a thickening at its front end io, through which the deflection of the contact spring i is limited. The pin 8 can also, as Fig. 3 shows, be hinged to the contact spring i and the connection bracket4 penetrate.

Die Druckfeder 9 besteht aus einem konisch gewickelten Runddraht oder aus einer konischen Pufferfeder.The compression spring 9 consists of a conically wound round wire or from a conical buffer spring.
