Description
Bei Zerhackern arbeiten die mittel- oder unmittelbar auf der Hauptfeder angebrachten Kontakte mit Gegenkontakten zusammen, die auf Schwingfedern sitzen, die durch gegebenenfalls einstellbare Widerlager unter vorausbestimmter -Vorspannung gehalten werden. Bei dieser Bauart liegt die Oberfläche der Arbeitskontakte nicht parallel der Längsachse der Hauptschwingfeder, so daß das Schleifen der Kontaktflächen sich besonders schwierig gestaltet. Außerdem war es notwendig, den Schwingfedern eine große Vorspannung zu geben und sie somit besonders stark zu machen. Diese Nachteile werden erfindungsgemäß dadurch beseitigt, daß. die Gegenfeder unter Einwirkung einer zweiten Feder gestellt ist und daß die Bewegungsmittelpunkte von Haupt- und Gegenfeder etwa in eine horizontale Ebene zu liegen kommen.In the case of choppers, they work directly or indirectly on the main spring attached contacts together with mating contacts that sit on oscillating springs, the possibly adjustable abutment under a predetermined pre-tension being held. In this design, the surface of the working contacts is not parallel to the longitudinal axis of the main oscillating spring, so that the grinding of the contact surfaces turns out to be particularly difficult. It was also necessary to use the swing springs to give a great bias and thus to make them particularly strong. These disadvantages are eliminated according to the invention that. the return spring under the action of a second spring is placed and that the centers of movement of the main and counter springs come to lie roughly in a horizontal plane.
In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung veranschaulicht:.In the drawing is an exemplary embodiment of the invention illustrates :.
Abb. i zeigt schaubildlich die einzelnen Teile des Arbeitskontaktes und Abib. 2 eine Seitenansicht von Hauptkontakt und Gegenkontakt.Fig. I shows a diagram of the individual parts of the normally open contact and Abib. 2 a side view of the main contact and mating contact.
Die Gegenfeder a trägt den Arbeitskontakt b und ist mit einer Aussparung c und einem Loch d ausgerüstet, mit welchem die Feder auf den Haltedorn aufgefädelt wird, der als Halterung des Kontaktsystems an der Platine vorgesehen ist. Ein starres Widerlager e legt sich an die eine Seite der Feder a an, während ;gegen die andere Federseite eine Feder k angreift, die aufgebogen oder gekröpft ist. ' Widerlager e und Feder h weisen gleichfalls zum Auffädeln auf den Dorn entsprechende Löcher i auf.The counter spring a carries the normally open contact b and is equipped with a recess c and a hole d with which the spring is threaded onto the retaining mandrel, which is intended to hold the contact system on the board. A rigid abutment e rests against one side of the spring a , while a spring k, which is bent or cranked, engages against the other side of the spring. 'Abutment e and spring h also have holes i for threading onto the mandrel.
Die Hauptfeder r, die von dem nicht dargestellten Magneten bzw. Anker in Schwingungen versetzt wird, trägt die Kontaktes. Ihr Bewegungsmittelpunkt ist bei t angedeutet, während. der entsprechende Punkt der Gegenfeder ca bei #e angeordnet -ist. Die Ein'spannebene ist mit y bezeichnet.The main spring r from the magnet or armature, not shown is set in vibration, the contact carries. Your center of movement is indicated at t while. the corresponding point of the return spring is located approx at #e -is. The clamping plane is denoted by y.
Bei der gezeichneten Bauart wird die Vorspannung nicht durch die Gegenfeder a selbst, sondern durch .die gekröpfte Feder h erzeugt, die oben bei o entsprechend gegen die Gegenfeder a drückt. Die Hilfsfeder h kann sehr weich hergestellt sein, und die notwendige Vorspannung läßt sich leicht durch eine entsprechende Durchbiegung erreichen. -Der Gegenfederkontakt kann nun eine geringere Schrägstellung a'ls. bisher erhalten, so. daß der parallel zur Hauptfeder geschliffene Arbeitskontakt auf der Hauptfeder mit der ganzen Fläche gegen den Gegenkontakt stößt.In the design shown, the preload is not provided by the counter spring a itself, but rather by the cranked spring h, which corresponds to o above presses against the return spring a. The auxiliary spring h can be made very soft, and the necessary preload can easily be achieved by bending it accordingly reach. -The counter spring contact can now be a'ls a less inclined position. until now received so. that the working contact ground parallel to the main spring on the Main spring pushes against the mating contact with the entire surface.
Ferner wird durch die Verwendung von zwei Federn a und h die Beanspruchung der Gegenfeder auf beide verteilt, ohne daß die Kontaktauslenkung verändert wird. Während bei Anwendung nur einer Gegenfeder die Abstandsschwankungen auch die Vorspannung beeinflussen, ist dies bei Verwendung zweier Federn weniger der Fall.Furthermore, by using two springs a and h, the stress on the counter spring is distributed to both without the contact deflection being changed. While when only one counter spring is used, the fluctuations in distance also affect the preload, this is less the case when using two springs.
Durch Verringerung des Querschnittes .durch die Aussparung c kann die Gegenfeder a dicht oberhalb der Einspannung y weicher als bisher gestaltet werden, und zugleich wird damit der Bewegungsmittelpunkt dem entsprechenden- -Punkt t der Hauptfeder r angepaßt, so daß die Arbeitskontaktflächen bei. der Berührung parallel aufeinanderzuliegen kommen, d. h. es ergibt sich während der Auslenkung ständig ein planes Aufliegen der Kontaktflächen.By reducing the cross section. Through the recess c can the return spring a just above the restraint y will be made softer than before, and at the same time the center of movement becomes the corresponding- point t the Main spring r adjusted so that the working contact surfaces at. parallel to the touch come to lie on top of each other, d. H. it arises continuously during the deflection a flat resting of the contact surfaces.
