Kontakteinrichtung mit Zusatzfederung, vorzugsweise für NH-Contact device with additional suspension, preferably for NH

SchmelzeinsätzeFusible links

Die Neuerung betrifft eine Kontakt einrichtung mit Zusatzfederung für mit Kontaktmessern versehene Schaltgeräte, insbesondere für NH-Schmelzeinsätze.The innovation concerns a contact device with additional suspension for switchgear with contact blades, especially for NH fuse links.

Es i'3t bekannt, als Zusatzfedern für Kontakt einrichtungen dieser Art ftingfedern zu verwenden, die unmittelbar an den kontaktgebenden Flächen angreifen und so den Kontaktdruck erhöhen» Dabei kann die Ringfeder lose durch eine öffnung des Kontaktfedersatzes hindurchgeführt werden. Eine andere Möglichkeit besteht darin, die ringförmige Feder mit dem Unterteil des Kdntaktfedersatzes fest zu ver-■ binden. Bei der Verwendung von mehreren, durch Schlitze voneinander getrennten Kontakt/alawellen wird ;jeder dieser Lamellen eine ringförmige Feder derart zugeordnet, daß diese parallel zu den Schlitzen zu liegen kommt. Diese Methode in eier Anordnung der zusätzlichen Federn erfordert natürlich höhere'Fertigungskosten.It i'3t known as auxiliary springs for contact devices of these Kind of spring springs to be used directly on the contact-making Attack surfaces and thus increase the contact pressure »The ring spring can loosely pass through an opening in the contact spring set will. Another possibility is to firmly connect the ring-shaped spring to the lower part of the contact spring set tie. If several contact / alawaves are used, separated from one another by slots, each of these lamellae becomes an annular one Assigned spring so that it comes to lie parallel to the slots. This method in an arrangement of the additional Springs, of course, require higher manufacturing costs.

Weiterhin ist in der bisherigen ArI; der Anbringung der Zusatzfedern ein Nachteil darin zu sehen, daß der. Kontaktdruck nur in einer bestimmten Zone des Kontaktfederaataes erhöht wird, nämlich dort, wo die Kraftangriffspunkte der ringförmigen Federn liegen. Das bedeutetFurthermore, in the previous ArI; the attachment of the additional springs a disadvantage to be seen in the fact that the. Contact pressure only in a certain Zone of the Kontaktfederaataes is increased, namely where the force application points of the annular springs are. That means

aber, daß nicht alle Stellen des zwisohen die Federlamellen eingeführten Kontaktmessers einen gleichmäßigen Anpreßdruck erfahren.but that not all places in the middle introduced the spring lamellae Contact knife experience a uniform contact pressure.

Gemäß der vorliegenden Neuerung werden die erwähnten Kängel dadurch vermieden, daß der vorzugsweise geschlitzte Kontaktfedersatz mit insbes. gleichen ringförmigen Zusatzfedern derart versehen ist, daß die Enüen der ringförmigen Federn an.i& verschiedenen senkrecht zu den Kontaktflächen achsparallel gelegten Ebenen liegenden Stellen der kontaktgebenden Teile des Kontaktfedersatzes angreifen.In accordance with the present innovation, the aforementioned kinks are thereby avoided that the preferably slotted contact spring set is provided with in particular the same annular additional springs in such a way that the enüen of the annular feathers an.i & different perpendicular to attack the contact surfaces lying planes parallel to the axis of the contact-making parts of the contact spring set.

Nähere Erläuterungen sollen anhand des in der Zeichnung dargestellten Ausführungsbeispiels gegeben werden«More detailed explanations should be based on what is shown in the drawing Embodiment are given «

Mit 1 ist die Anschlußschiene des Kontaktfedersatzes 2 bezeichnet, der auf einem vorzugsweise keramischen Träger 12 befestigt ist. . 3 stellt das Kontaktmesser des Schmelzeinsatzes 11 dar. Durch eine öffnung 4, die an beliebiger Stelle des Federsatzes 2 angeordnet sein kann, greifen zwei gleichartige Federringe 5 hindurch. Die Enden 6 und 7 dieser Ringfedern liegen vorzugsweise in schwachen Einkerbringen, Vertiefungen 8,9 oder dgl. Die Ringfedern sind den Lamellen derart zugeordnet, daß ihnen in verschiedenen Zonen beim Einfahren des Kontaktmessers 3 ein zusätzlicher Anpreßdruck verliehen wird. Dabei ist es von besonderem Vorteil, daß für die als Abr^ißstelle dienende Lamelle der höher liegende, d.h. der der oberen Begrenzungakante 10 des Federsatzes nächst liegende Angriffspunkt der Federkraft bestimmt ist. Mit dieser Verteilung der Angriffsstellen der Zusatzfedern ist eine gute Ausnutzung der kontaktgebenden Flächen derartiger Ko:itaktanordnungen gewährleistet.1 with the connecting rail of the contact spring set 2 is designated, which is attached to a preferably ceramic carrier 12. . 3 shows the contact blade of the fuse link 11. By a Opening 4, which can be arranged at any point on the set of springs 2, is passed through by two similar spring rings 5. The ends 6 and 7 of these ring springs are preferably in weak ones Notching, depressions 8, 9 or the like. The annular springs are assigned to the lamellae in such a way that they are in different zones when retracting the contact blade 3, an additional contact pressure is awarded. It is of particular advantage that for the lamella serving as the tear-off point, the one lying higher, i.e. the the upper delimitation edge 10 of the set of springs closest to the point of application the spring force is determined. With this distribution of the points of attack of the additional springs is a good utilization of the contact-making Surfaces of such Ko: itact arrangements guaranteed.
