Abstract

A relay having a coil, a magnet system and a contact system which is produced from an electrically insulating material, can be operated by a comb and has two pole paths, these elements all being arranged in a housing which consists of a base body and a cover. In order to achieve separation of the pole paths, it is provided that the comb (6) has a flap (7) which is in the form of a plate, runs between two pole paths of the contact system and is guided in grooves (9, 16) which are arranged in the base body (1) and/or in the cover (17). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Relais gemäß dem Oberbegriff des Anspruches 1.The invention relates to a relay according to the preamble of claim 1.

Bei derartigen Relais sind die Polstrecken des Kontaktsystems entweder nur durch Luftstrecken oder durch feststehende Rippen voneinander getrennt, wobei der Kamm meist T-förmig oder U-förmig ausgebildet ist und am Anker und den beweglichen Teilen abgestützt ist, bzw. in diese eingreift. Der Nachteil dieser bekannten Relais liegt darin, daß es bei Überspannungen zu einem Überschlag zwischen den Polstrecken kommen kann, wenn die Trennung nur durch Luftstrecken erfolgt, und daß bei der Ausführung mit Rippen die erforderlichen Luft- und Kriechstrecken zwischen den Polstrecken des Kontaktsystems eine Miniaturisierung erschweren.In such relays, the pole sections of the contact system are separated from one another either only by air gaps or by fixed ribs, the comb mostly being T-shaped or U-shaped and supported on the armature and the moving parts, or engaging in these. The disadvantage of these known relays is that there can be a flashover between the pole paths in the event of overvoltages if the separation is only by air gaps, and that the required air and creepage distances between the pole gaps of the contact system make the miniaturization difficult when using ribs .

Ziel der Erfindung ist es diese Nachteile zu vermeiden, und ein Relais der eingangs erwähnten Art vorzuschlagen, bei dem auf einfache Weise ein Überschlag zwischen den Polstrecken verhindert wird, und eine miniaturisierte Ausführung möglich ist.The aim of the invention is to avoid these disadvantages and to propose a relay of the type mentioned in the introduction in which a flashover between the pole paths is prevented in a simple manner and a miniaturized design is possible.

Erfindungsgemäß wird dies bei einem Relais der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is achieved in a relay of the type mentioned at the outset by the characterizing features of claim 1.

Durch diese Merkmale ist sichergestellt, daß die Polstrecken des Relais durch ein elektrisch isolierendes Material voneinander getrennt sind. Dabei ergibt sich durch die Führung des Kammes in den Nuten der Vorteil entsprechend langer Kriechwege.These features ensure that the pole sections of the relay are separated from one another by an electrically insulating material. The guiding of the comb in the grooves results in the advantage of correspondingly long creepage distances.

Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil, daß der Kamm relativ klein gehalten werden kann und auch bei geringer Dicke eine ausreichende Steifigkeit aufweist.The features of claim 2 have the advantage that the comb can be kept relatively small and has sufficient rigidity even with a small thickness.

Durch die Merkmale des Anspruches 3 ergibt sich eine sehr einfache Konstruktion, bei der sich eine sehr sichere Führung des Kammes ergibt.The features of claim 3 result in a very simple construction in which there is a very safe guidance of the comb.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 schematisch ein erfindungsgemäßes Relais mit teilweise weggebrochenem Deckel,
  • Fig. 2 das Relais nach Fig. 1 mit weggebrochener Stirnwand des Deckels, wobei das Kontaktsystem weggelassen ist und
  • Fig. 3 eine axonometrische Draufsicht auf das Relais nach den Fig. 1 und 2 mit teilweise weggebrochenem Deckel.
The invention will now be explained in more detail with reference to the drawing. Show:
  • 1 schematically shows a relay according to the invention with the cover partially broken away,
  • Fig. 2 shows the relay of Fig. 1 with the front wall of the cover broken away, the contact system being omitted and
  • Fig. 3 is an axonometric top view of the relay according to FIGS. 1 and 2 with the cover partially broken away.

Das Relais weist einen Grundkörper 1 auf, in dem die festen Kontakte 2 und 3, bzw. die Kontaktträger 20, 3' eingesetzt sind. Dabei weist das Kontaktsystem zwei Polstrecken auf, von denen nur eine in der Fig. 1 dargestellt ist.The relay has a base body 1, in which the fixed contacts 2 and 3, or the contact carriers 20, 3 'are inserted. The contact system has two pole sections, only one of which is shown in FIG. 1.

Im Grundkörper ist weiters eine Spule 4 gehalten die ein Magnetsystem aufnimmt. Dabei greift ein Anker 5 in einen Kamm 6 ein, der an der Oberseite der Aufnahme der Spule 4 aufliegt und auf dieser verschiebbar ist. Der Kamm 6 ist im wesentlichen lyraförmig gestaltet und hält einen Lappen 7 zwischen Ansätzen 8. Dieser Lappen 7 ist in einer Nut 9 geführt, die in einem zwischen den Polstrecken angeordneten Steg 10 des Grundkörpers 1 eingearbeitet ist, wobei die Nut 9 in einer Kopfleiste 11 des Steges 10 angeordnet ist.A coil 4 is also held in the base body and receives a magnet system. An armature 5 engages in a comb 6, which rests on the top of the receptacle of the coil 4 and is displaceable thereon. The comb 6 is essentially lyra-shaped and holds a tab 7 between the lugs 8. This tab 7 is guided in a groove 9, which is incorporated in a web 10 arranged between the pole sections of the base body 1, the groove 9 in a header 11 of the web 10 is arranged.

Die Ansätze 8 des Kammes 6 dienen gleichzeitig als Mitnehmer für die bewegliche Kontaktfeder 12, die einen bewegliche Kontakte 23 trägt. Diese Kontaktfeder 12 ist im wesentlichen U-Förmig ausgebildet und ist an einem Kontakträger 12' befestigt, der auch eine Anschlußfahne 13 aufweist. Der Feste Kontakt 21 ist ebenfalls mit einer Anschlußfahne 14 versehen, desgleichen der Kontakträger 3', der eine Anschlußfahne 15 aufweist, wobei die Anschlußfahnen den Grundkörper 1 durchsetzen. Dabei ist an dem Kontaktträger 3' ein federnder Halter 21 mit Nieten 22 befestigt, in dem der feste Kontakt 3 gehalten ist.The lugs 8 of the comb 6 also serve as drivers for the movable contact spring 12, which carries a movable contacts 23. This contact spring 12 is essentially U-shaped and is fastened to a contact carrier 12 ', which also has a connecting lug 13. The fixed contact 21 is also provided with a connecting lug 14, as is the contact carrier 3 ', which has a connecting lug 15, the connecting lugs passing through the base body 1. In this case, a resilient holder 21 with rivets 22 is fastened to the contact carrier 3 ', in which the fixed contact 3 is held.

Wie aus der Fig. 2 zu ersehen ist, kann der Lappen 7 auch in einer Nut 16 eines Deckels 17 geführt sein, die in einer nach innen vorspringenden Leiste 18 eingearbeitet ist.As can be seen from FIG. 2, the tab 7 can also be guided in a groove 16 of a cover 17, which is incorporated in an inwardly projecting strip 18.

Weiters ist der Lappen 7 in einer Nut 18 geführt, die in einer Leiste 19 der Stirnwand des Deckels 17 angeordnet ist, wobei die Leiste 19 in das Innere des Deckels 17 vorspringt.Furthermore, the tab 7 is guided in a groove 18 which is arranged in a strip 19 of the end wall of the cover 17, the strip 19 projecting into the interior of the cover 17.

Der Lappen 7, der ebenso wie der Kamm 6 aus einem elektrisch isolierenden Material hergestellt ist, trennt in Verbindung mit dem Steg 9 und der Leiste 18 des Deckels 17 die beiden Polstrecken des Kontaktsystems, von denen nur eine 2, 3, 12 dargestellt ist.The tab 7, which, like the comb 6, is made of an electrically insulating material, separates the two pole sections of the contact system, only one of which 2, 3, 12 is shown, in connection with the web 9 and the strip 18 of the cover 17.
