Description

Die Erfindung bezieht sich auf eine Kontaktanordnung für ein Schaltgerät mit Mehrfachunterbrechung durch parallel geschaltete Kontaktberührungsstellen zweier in einem Kontaktbetätigungsglied über einen Federteller für die Kontaktdruckfeder geführter Kontaktbrücken, wobei der Federteller quer zur Federungsrichtung Einschnitte hat, in die die Kontaktbrücken mit dem Federteller verrastbar quer zu ihrer Längsrichtung einschiebbar sind.The invention relates to a contact arrangement for a switching device with multiple interruption through parallel contact contact points of two contact bridges guided in a contact actuator via a spring plate for the contact pressure spring, the spring plate having cuts transversely to the direction of suspension, into which the contact bridges can be locked with the spring plate transversely to their longitudinal direction can be inserted.

Bei einer bekannten Kontaktanordnung der obengenannten Art (DE-PS 22 53 918) wird der Federteller mit ebenen Flächen im Kontaktbetätigungsglied geführt. Zur Anpassung der einzelnen Kontaktbrücken an die Gegenkontakte haben die Kontaktbrücken im Federteller ein relativ großes Spiel, und sie sind selbst auch elastisch ausgeführt. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verkanten des Federtellers in der Schieberführung zu vermeiden und eine sichere Kontaktgabe der beiden Kontaktbrücken auch bei nicht gleichmäßigem Fluchten der beiden Festkontaktstücke zu ermöglichen. Dies wird auf einfache Weise dadurch erreicht, daß der Federteller zumindest an zwei gegenüberliegenden, quer zur Längsrichtung der Kontaktbrücke verlaufenden Gleitflächen des Federtellers im Kontaktbetätigungsglied gerundet ist. Um das Kippen der Kontaktbrücken in mehreren Richtungen jedoch bei seitlicher Führung des Federtellers zu ermöglichen ist es vorteilhaft, wenn der Federteller über die Längsseiten der Kontaktbrücken hinausragt und von dem Kontaktbeätigungsglied U-förmig umgriffen wird und im überragenden Bereich an jeweils beiden senkrecht zueinander liegenden Gleitflächen gerundet ist. Zum Einbringen der Kontaktbrücken in La 2 Syr / 21.03.1984 den Federteller bei guten Gleiteigenschaften im Kontaktbetätigungsglied hat es sich als vorteilhaft erwiesen, wenn der Federteller aus thermoplastischem Formstoff besteht. Um eine gute Auflage für die Feder im Federteller zu schaffen und zusätzlich das Umsetzen des Federtellers um 180° zur Erzielung von Schließer- bzw. Offnerkontakten zu ermöglichen ist es weiterhin vorteilhaft, wenn der Federteller im wesentlichen H-förmigen Querschnitt hat. An beiden Längsseiten des H sind hier Ausnehmungen für die Feder vorgesehen.In a known contact arrangement of the type mentioned above (DE-PS 22 53 918) the spring plate is guided with flat surfaces in the contact actuator. To adapt the individual contact bridges to the mating contacts, the contact bridges in the spring plate have a relatively large amount of play, and they themselves are also designed to be elastic. The present invention has for its object to avoid tilting of the spring plate in the slide guide and to enable reliable contacting of the two contact bridges even when the two fixed contact pieces are not evenly aligned. This is achieved in a simple manner in that the spring plate is rounded at least on two opposite sliding surfaces of the spring plate in the contact actuating member, which slide surfaces extend transversely to the longitudinal direction of the contact bridge. In order to enable the contact bridges to tilt in several directions, however, when the spring plate is guided laterally, it is advantageous if the spring plate protrudes beyond the longitudinal sides of the contact bridges and is encompassed in a U-shape by the contact actuating member and rounded in the outstanding area on each of the two mutually perpendicular sliding surfaces is. To insert the contact bridges in La 2 Syr / 21.03.1984 the spring plate with good sliding properties in the contact actuator, it has proven to be advantageous if the spring plate consists of thermoplastic molding material. In order to create a good support for the spring in the spring plate and additionally to enable the spring plate to be moved through 180 ° in order to make normally open or normally closed contacts, it is also advantageous if the spring plate has an essentially H-shaped cross section. On both long sides of the H there are recesses for the spring.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben und die Wirkungsweise näher erläutert.An exemplary embodiment according to the invention is described with reference to the drawing and the mode of operation is explained in more detail.

Es zeigen:

  • Fig. 1 eine Draufsicht auf die in den Federteller eingesetzten Kontaktbrücken mit Kontaktbetätigungsglied, zum Teil im Schnitt,
  • Fig. 2 eine Vorderansicht auf die Kontaktanordnung nach Fig. 1, ebenfalls teilweise im Schnitt, und
  • Fig. 3 eine Seitenansicht auf die Anordnung nach Fig. 1, ebenfalls teilweise im Schnitt.
Show it:
  • 1 is a plan view, partly in section, of the contact bridges with contact actuating element inserted into the spring plate,
  • Fig. 2 is a front view of the contact arrangement of FIG. 1, also partially in section, and
  • Fig. 3 is a side view of the arrangement of FIG. 1, also partially in section.

Die in der Zeichnung dargestellte Kontaktanordnung für ein nicht näher dargestelltes Schaltgerät mit Mehrfachunterbrechung besteht aus zwei Kontaktbrücken 1, 2, die mit den die Kontaktberührungsstellen bildenden Kontaktauflagen 3 versehen sind, dem Federteil 4, der Kontaktdruckfeder 5 und dem eigentlichen Kontaktbetätigungsglied 6. Das Kontaktbetätigungsglied 6 hat eine fensterförmige Uffnung 7, an deren einer Seite sich die Kontaktdruckfeder 5 abstützt und an deren anderer Seite - wie Fig. 3 zeigt - die Kontaktbrücken 1 und 2 über den Federteller 4 anliegen. Der Federteller hat seitlich Einschnitte 8, in die die Kontaktbrücken 1 und 2 eingeschoben werden; Noppen 9 an den Kontaktbrücken 1, 2 rasten hierbei in entsprechende seitenförmige Ausnehmungen 10 in den Federteller 4 ein, so daß eine gewisse Beweglichkeit der Kontaktbrücken 1, 2 gegenüber dem Federteller 4 erhalben bleibt. Eine Verschiebung ist jedoch ausgeschlossen. Wie die Fig. 1 zeigt, ragt der Federteller mit dem Teil 11 über die Längsseiten der Kontaktbrücken 1, 2 hinaus. Die Teile 11 werden von U-förmigen Aussparungen 12 in den Seitenwänden des Kontaktbetätigungsgliedes umragt, so daß der Federteller sowohl an den Seitenwänden 13 der fensterförmigen Öffnung 7 als auch an den hierzu senkrecht verlaufenden Wänden 14 gleitend geführt sind. Die den Seitenwänden 13 bzw. 14 zugewandten Gleitflächen 15 des Federtellers sind sowohl in bezug auf die Seitenwand 13 als auch in bezug auf die Seitenwand 14 gerundet. Hierdurch ergibt sich die Möglichkeit, daß die Kontaktbrücke sowohl in Längsrichtung mitsamt dem Federteller als auch quer dazu kippen, d.h. sich bewegen kann, so daß sich die Kontaktbrücken einerseits an schiefstehende Festkontaktteile 16 als auch um seine Längsachse zum Ausgleich von Toleranzen drehen kann. Die beiden Schwenkrichtungen sind durch die Pfeile 17 in Fig. 1 und 18 in Fig. 3 dargestellt.The contact arrangement shown in the drawing for a switching device with multiple interruptions, not shown, consists of two contact bridges 1, 2, which are provided with the contact pads 3 forming the contact contact points, the spring part 4, the contact pressure spring 5 and the actual contact actuator 6. The contact actuator 6 has a window-shaped opening 7, on one side of which the contact pressure spring 5 is supported and on the other side - as shown in FIG. 3 - the contact bridges 1 and 2 rest over the spring plate 4. The spring plate has incisions 8 on the side the contact bridges 1 and 2 are inserted; Nubs 9 on the contact bridges 1, 2 snap into corresponding side recesses 10 in the spring plate 4, so that a certain mobility of the contact bridges 1, 2 relative to the spring plate 4 remains. A shift is however impossible. As shown in FIG. 1, the spring plate with the part 11 protrudes beyond the long sides of the contact bridges 1, 2. The parts 11 are surrounded by U-shaped recesses 12 in the side walls of the contact actuator, so that the spring plate is slidably guided both on the side walls 13 of the window-shaped opening 7 and on the walls 14 running perpendicular thereto. The sliding surfaces 15 of the spring plate facing the side walls 13 and 14 are rounded both with respect to the side wall 13 and with respect to the side wall 14. This results in the possibility that the contact bridge can tilt in the longitudinal direction together with the spring plate as well as transversely thereto, ie can move, so that the contact bridges can on the one hand turn to crooked fixed contact parts 16 and about its longitudinal axis to compensate for tolerances. The two pivot directions are represented by the arrows 17 in FIGS. 1 and 18 in FIG. 3.

Durch die Pendelmöglichkeit des Federtellers ergibt sich somit eine optimale Anpassung der Kontaktbrücken an die Festkontaktteile, ohne daß hierbei ein Verklemmen des Federtellers in der Führung zu befürchten ist. Zum Einbringen der Federteller in das Kontaktbetätigungsglied ist dieses hier in ein Unterteil 19 und ein Oberteil 20 aufgeteilt, das beispielsweise über Schnappverbindungen nach Einlegen der Feder in den Federteller mit den Kontaktbrücken zusammengefügt werden kann.The possibility of pendulum of the spring plate thus results in an optimal adaptation of the contact bridges to the fixed contact parts, without fear of jamming of the spring plate in the guide. To insert the spring plate into the contact actuator, the latter is divided here into a lower part 19 and an upper part 20, which can be joined to the contact bridges, for example by snap connections after the spring has been inserted into the spring plate.
