Description
DEUTSCHESGERMAN
Die Erfindung betrifft einen elektrischen Schnappschalter mit einem in Längsrichtung biegsamen und unter Vorspannung stehenden Federblatt, dessen eines Ende unter Zuhilfenahme eines am Federblatt anliegenden Stützgliedes fest eingespannt ist und das von dem Betätigungsglied durch Druck auf zwei Stellen in Querrichtung gebogen wird, wodurch eine Biegung in Längsrichtung erzielt wird.The invention relates to an electrical snap switch with a longitudinally flexible and spring leaf under tension, one end of which is resting against the spring leaf with the aid of a spring leaf Support member is firmly clamped and that of the actuator by pressing on two Places in the transverse direction is bent, whereby a bend in the longitudinal direction is achieved.
Bei einem elektrischen Schnappschalter dieser Art läßt die Zuverlässigkeit der Schnappwirkung zu wünschen übrig, und es stellen sich unerwünschte Schwingungserscheinungen ein.In an electrical snap switch of this type, the reliability of the snap action allows to be desired, and there are undesirable vibration phenomena.
Der Erfindung liegt die Aufgabe zugrunde, diese Mängel zu vermeiden.The invention is based on the object of avoiding these shortcomings.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Druck an denjenigen Stellen auf die Schnappfeder ausgeübt wird, zwischen denen die Spitze des Stützgliedes auf der Feder aufliegt.This object is achieved in that the pressure at those points on the Snap spring is exercised, between which the tip of the support member rests on the spring.
Vorzugsweise hat das Stützglied einen Teil, welcher der Befestigung des Federblattes an einer Plattform dient, und einen gebogenen Teil, welcher mit seiner Spitze an dem Federblatt anliegt.Preferably, the support member has a part which is used to attach the spring leaf to a platform serves, and a curved part, which rests with its tip on the spring leaf.
Dabei kann die Plattform Längsleisten bilden, die im Abstand voneinander angeordnet sind und zwischen denen sich diejenige Zone des Federblattes befindet, an welcher das Stützglied anliegt.The platform can form longitudinal strips which are arranged at a distance from one another and between which is that zone of the spring leaf on which the support member rests.
Dabei kann die Anordnung so getroffen sein, daß das die Durchbiegung der Blattfeder beeinflussende Stützglied stumpfwinklig gebogen ist und durch die Einspannung der Blattfeder unter einer \rorspannung steht, die den Winkel aufzubiegen sucht und das Stützglied mit seiner Spitze in Anlage an der Blattfeder hält.The arrangement may be such that the deflection of the leaf spring influencing support member is an obtuse angle bent and stands by the clamping of the leaf spring under an \ r noise voltage, which seeks aufzubiegen the angle and holds the support member with its tip in contact with the leaf spring.
Der Schalter nach der Erfindung eignet sich besonders für kleine Abmessungen, bei denen das Federblatt beispielsweise 12 mm lang sein kann und aus Federstahl von einer Stärke von 0,05 bis 0,10 mm hergestellt wird.The switch according to the invention is particularly suitable for small dimensions in which the spring leaf for example 12 mm long and made of spring steel with a thickness of 0.05 to 0.10 mm will be produced.

Fig. 6 eine schaubildliche Ansicht des erfindungsgemäß vorgesehenen Stützgliedes zum Beherrschen der Schnappwirkung des Federblattes.6 is a perspective view of the control support member provided according to the invention the snap action of the spring leaf.
Das Isolierstoffgehäuse 5 des Schalters ist zweiteilig ausgestaltet; es besteht aus einem Unterteil 6 und einer Kappe 7. Der Unterteil ist an dem einen Ende mit einer Plattform 8 und am anderen Ende mit einem Sockel 9 versehen.The insulating housing 5 of the switch is designed in two parts; it consists of a lower part 6 and a cap 7. The lower part is provided with a platform 8 at one end and a base 9 at the other end.
Die Plattform 8 trägt eine Blattfeder 10, während der Sockel 9 eine Kontaktplatte 11 trägt. Unterhalb der Platte 11 ist der Unterteil 6 mit einer zweiten Kontaktplatte 12 versehen. Auf dem freien Ende des Federblatts 10 ist ein Kontaktstück 13 angeordnet, das für gewöhnlich mit der Platte 11 in Stromschluß steht, wie gezeigt, aber sich beim Herunterschnappen der Blattfeder an die Platte 12 anlegt.The platform 8 carries a leaf spring 10, while the base 9 carries a contact plate 11. Below the plate 11 , the lower part 6 is provided with a second contact plate 12. A contact piece 13 is arranged on the free end of the spring leaf 10 , which is usually in current connection with the plate 11 , as shown, but rests against the plate 12 when the leaf spring snaps down.
Zum Befestigen des Federblatts 10 an der Plattform 8 dient der Schaft 14 einer Leitungsklemme 15. In entsprechender Weise dienen zum Befestigen der Kontaktplatten 11 und 12 Leitungsklemmen 16 und 17. To fasten the spring leaf 10 to the platform 8 , the shaft 14 of a line clamp 15 is used. In a corresponding manner, line clamps 16 and 17 are used to fasten the contact plates 11 and 12.
Der Deckel 7 hat einen Sockel 18, in welchem ein Schaltglied 19 für das Federblatt 10 auf und ab- beweglich geführt ist. Dieses Schaltglied hat zwei Ansätze 20, deren Abstand die Breite der Plattform 8 übertrifft (vgl. Fig. 2 und 5) und die dem Zweck dienen, sich beim Niederdrücken des Schaltgliedes 19 auf gegenüberliegende seitliche Randzonen des Federblattes zu legen und diese abwärts zu biegen. Dadurch erfährt das Federblatt eine Biegung in Querrichtung, wie ein Vergleich der Fig. 4 und 5 erkennen läßt, da es zwischen den seitlichen Randzonen durch die Plattform 8 abgestützt ist.The cover 7 has a base 18 in which a switching element 19 for the spring leaf 10 is guided so that it can be moved up and down. This switching element has two approaches 20, the distance between which exceeds the width of the platform 8 (cf. FIGS. 2 and 5) and which serve the purpose of lying on opposite lateral edge zones of the spring leaf when the switching element 19 is pressed down and bending them downwards. As a result, the spring leaf experiences a bend in the transverse direction, as can be seen by comparing FIGS. 4 and 5, since it is supported by the platform 8 between the lateral edge zones.
Die Blattfeder ist an dem rechten Ende bei1 42 geschlitzt und hat daher zwei Finger 21. Diese sindThe leaf spring is slotted at the right end at 1 42 and therefore has two fingers 21. These are
