Description
Es sind feststehende Schaltstücke, die einen Schaltstift umschließen, für Schalter bekannt. Diesfea Schaltstück besteht aus einzelnen kreisf6rmig angeordneten Kontaktfingern, die. durch Ringfedern zusammengehalten werden.They are fixed contact pieces that enclose a contact pin, known for switches. This contact piece consists of individual circularly arranged Contact fingers that. are held together by ring springs.
Gemäß der Erfindung besitzen die einzelnen Kontaktfinger seitliche Vorsprünge, die in entsprechende Ausnehmungen der Nachbarfinger eingreifen; in solcher Lage zur Kontaktstelle, daß die Ringfeder gegen Zutritt beim Schalten entstehender heißer Gase geschützt ist. Dadurch wird eine Gefährdung der Ringfedern beim Schalten vermieden. Besonders vorteilhaft tist es, die Vorsprünge alis Überlappungskragen auszubilden, in denen die Ringfeder, z. B. ein Gummiring, liegt.According to the invention, the individual contact fingers have lateral Projections which engage in corresponding recesses in the neighboring fingers; in such Position to the contact point that the ring spring against access when switching arising protected from hot gases. This puts the ring springs at risk when shifting avoided. It is particularly advantageous to use the projections as the overlap collar train in which the ring spring, z. B. a rubber ring is located.
In :der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In: the drawing shows an embodiment of the invention.
Fig. t1 zeigt die Ansicht des Schaltfingers von vorn, Fig. 2 einen Schnitt, Fi'g. 3 die Ansicht von rückwärts und Fig. 4 den Grundriß.Fig. T1 shows the view of the shift finger from the front, Fig. 2 shows a Section, Fi'g. 3 shows the view from the rear and FIG. 4 shows the plan.
Der Kontaktfinger besitzt einen @Überlappungskragen 2 und eine Ausnehinung 3, in welche. ,der Kragen des benachbarten Fingers eingreift: In .den Kragen wird die Ringfeder, im Ausführungsbeispiel der Gummiring 5, eingelegt.The contact finger has an overlap collar 2 and a recess 3, in which. , the collar of the adjacent finger engages: In .the collar is the ring spring, in the exemplary embodiment the rubber ring 5, is inserted.
In den Fig. 5 und 6 ist der Hohlkontakt dargestellt, und zwar zeigt Fig. 5 einen Schnitt längs der Linie A-B-C :der Fig. 6, während Fig. 6 im oberen Teil die Ansicht und im unteren Teil einen Schnitt längs :der Linie D-E zeigt. Wise aus den Fig. 4 und 5 hervorgeht, sind die Finger auf einem Kreisbogen angeordnet und werden durch einen Gummiring 5; der in den Kragen eingelegt ist und durch zwei Gummiringe 6, die in die Ausnehmung 4 eingelegt sind, zusammengehalten. Mit 7 ist der Kontaktstift bezeichnet. Die Kontaktfinger besitzen noch eine Ausnehmung 8, in die eine Mutter 9 mit einem Schraubenbolzen 1o einsgelegt ist, damit :der Konus 11 angezogen werden kann, durch welchen im gewünschten Maße :die Schaltfinger auseinandergedrüdkt werden. In dem unteren Teil der Fig..6 sieht man die 'kragenförmi:gen Vorsprünge und Ausnehmungen in der Lage, wenn der Schaltstift eingeführt ist. Wird der Schaltstift herausgezogen, so. drückt die Gummifeder 5 die Kontaktfinger zusammen. Durch diese kragenförmigen Vorsprünge und tdurch ,die Ausnehmungen wird erreicht, daß beim Herausziehen des Schaltstiftes die entstehenden Gase nicht den Gummiring 5 gefährden.In Figs. 5 and 6, the hollow contact is shown, namely shows Fig. 5 shows a section along the line A-B-C: of Fig. 6, while Fig. 6 in the upper Part of the view and in the lower part a section along: the line D-E shows. Wise 4 and 5, the fingers are arranged on an arc of a circle and are secured by a rubber ring 5; which is inserted into the collar and through two Rubber rings 6, which are inserted into the recess 4, held together. With 7 is the contact pin denotes. The contact fingers also have a recess 8, into which a nut 9 is inserted with a screw bolt 1o so that: the cone 11 can be tightened, by which to the desired extent: the shift fingers apart will. In the lower part of Fig..6 you can see the 'collar-shaped projections and recesses in the position when the switch pin is inserted. Will the switch pin pulled out so. the rubber spring 5 presses the contact fingers together. Through this collar-shaped projections and t through, the recesses is achieved that when pulling out of the switching pin, the gases generated do not endanger the rubber ring 5.
