Le relais comporte un organe de commande (7) relié à l'induit (6), organe de commande qui couvre, au moyen d'une paroi de séparation (76), la totalité de la surface comprise entre le système magnétique (2, 4, 5) et le système de contact (8) et qui entoure, par des parois latérales (71, 72, 74) formant des cuvettes, le système de contact (8) et/ou le système magnétique (2, 3, 4, 5). Le relais permet d'obtenir ainsi, avec des dimensions réduites, des lignes de fuite et des entrefers très longs entre la bobine et le système de contact.The relay comprises a control member (7) connected to the armature (6), a control member which covers, by means of a partition wall (76), the entire surface between the magnetic system (2, 4, 5) and the contact system (8) and which surrounds, by side walls (71, 72, 74) forming bowls, the contact system (8) and / or the magnetic system (2, 3, 4) , 5). The relay thus makes it possible to obtain, with reduced dimensions, very long creepage lines and air gaps between the coil and the contact system.

Description

Elektromagnetisches Relais Electromagnetic relay
Die Erfindung betrifft ein elektromagnetisches Relais mit einem Magnetsystem mit Spule, Kern und Anker, einem benachbart zur Spule angeordneten Kontaktsystem mit mindestens einem bewegli¬ chen Kontaktelement und mit einem im Bereich zwischen dem Ma- gnetsystem und dem Kontaktsystem angeordneten Betätigungsele¬ ment aus Isolierstoff, welches durch den Anker bewegbar ist und sich als bewegliche Trennwand im wesentlichen über die gesamte Fläche zwischen den Metallteilen des Magnetsystems einerseits und des Kontaktsystems andererseits erstreckt.The invention relates to an electromagnetic relay with a magnet system with coil, core and armature, a contact system arranged adjacent to the coil with at least one movable contact element and with an actuating element made of insulating material which is arranged in the area between the magnetic system and the contact system is movable by the armature and extends as a movable partition essentially over the entire area between the metal parts of the magnet system on the one hand and the contact system on the other hand.
Aus der DE-27 33 80C-A1 is. bereits ein derartiges Relais be¬ kannt, wobei das Magnetsystem neben dem Kontaktsystem auf einem gemeinsamen Eoden angecrdnet ist. Die Betätigung der Kontakt¬ elemente erfolgt über eine winkelförmigen Anker, dessen Betä- tigungsschenkel annähernd parallel zur Spulenachse zwischenFrom DE-27 33 80C-A1 is. Such a relay is already known, the magnet system being connected to a common electrode in addition to the contact system. The contact elements are actuated via an angular armature, the actuating arm of which is approximately parallel to the coil axis between
Spule und Kontaktsystem liegt und ein im wesentlichen parallel dazu angeordnetes, quaderförmiges Betätigungsteil bewegt. Die¬ ses Betätigungsteil ist dcrt gleichzeitig Träger für die beweg¬ licher, Elemente vcn Erückenkontakteinheiten. Da sich das er- wähnte Betätigungsteil bei αem bekannten Relais im wesentlichen über die gesamte Länge des Innenraums des Relais erstrecken soll, wirkt es als isolierende Trennwand zwischen Magnetsystem und Kontaktsystem. Allerdings sind die Isolierstrecken (Kriech- und Luftstrecken), die seitlich am Rande des Betätigungsele en- tes zu messen sinα, für bestimmte Anwendungsfälle nicht ausrei¬ chend, wenn die Gesamtabmessungen des Relais auf ein bestimmtes Maß verkleinert werden sollen. Zudem ist es für eine Miniaturi¬ sierung des Relais hinderlich, daß zwischen Magnetsystem und dem Betätigungselement ein Ankerarm liegt, der verhältnismäßig viel Platz beansprucht.Coil and contact system is located and moves a parallelepiped-shaped actuating part arranged substantially parallel thereto. This actuating part is at the same time a carrier for the movable elements of the back contact units. Since the actuating part mentioned in αem known relays is intended to extend essentially over the entire length of the interior of the relay, it acts as an insulating partition between the magnet system and the contact system. However, the insulating distances (creepage distances and clearances) which have to be measured laterally at the edge of the actuating element are not sufficient for certain applications if the overall dimensions of the relay are to be reduced to a certain extent. In addition, it is a hindrance for miniaturization of the relay that there is an armature arm between the magnet system and the actuating element, which arm arm takes up a relatively large amount of space.
Aus cer DE-2B 30 390-A1 ist weiterhin ein elektromagnetisches Relais der eingangs genannten Art bekannt, bei der ein polari¬ siertes Magnetsystem mit einem sogenannten H-Anker oberhalb des Kontaktsystems liegt und ein mit dem Anker verbundener Kunst¬ stoffteil einen im wesentlichen plattenförmigen Abschnitt zur Übertragung der Ankerbewegung auf das Kontaktsystem aufweist. Auch dort gilt, daß die Kriech- und Luftstrecken zwischen dem Kontaktsystem und den Metallteilen des Magnetsystems im Randbe¬ reich des Betätigungsteiles sehr hohen Isolationsanforderungen nicht genügen und daß andererseits der Anker mit dem erwähnten plattenförmigen Betätigungsteil sowie mit zusätzlich zwischen¬ geschalteten weiteren Betätigungsteilen verhältnismäßig viel Volumen benötigt, was einer extremen Miniaturisieruπg eines derartigen Relais bei gleichzeitig hoher Spannungsfestigkeit widerspricht.From cer DE-2B 30 390-A1 is also an electromagnetic Relays of the type mentioned are known, in which a polarized magnet system with a so-called H-armature lies above the contact system and a plastic part connected to the armature has an essentially plate-shaped section for transmitting the armature movement to the contact system. It also applies there that the creepage distances and clearances between the contact system and the metal parts of the magnet system in the edge region of the actuating part do not meet very high insulation requirements and that, on the other hand, the armature with the plate-shaped actuating part mentioned and also with additional actuating parts interposed in addition has a relatively large volume needed, which contradicts an extreme miniaturization of such a relay with high dielectric strength.
Ziel der Erfindung ist es, ein Relai. der eingangs genannten Art sc auszubilden, daß mit möglichst wenigen, einfach zu mon¬ tierenden Einzelteilen bei äußerst geringen Gesamtabmessungen sehr große Isolierstrecken zwischen Magnetsystem und Kontaktsy- stem gewonnen werden.The aim of the invention is a relay. of the type mentioned at the outset, such that very large insulating distances between the magnet system and the contact system are obtained with the fewest possible, easy-to-assemble individual parts with extremely small overall dimensions.
Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß das Be- tätigungselemer.t mit an der Trennwand angeformten, zum Magnet¬ system und/oder zum Kentaktsystem gerichteten Seitenwänden das Magnetsystem und/oder das Kentaktsystem wannenförmig zumindest teilweise umschließt.According to the invention, this aim is achieved in that the actuating element at least partially encloses the magnet system and / or the Kentakt system in the form of a trough with side walls formed on the partition wall and directed towards the Magnet¬ system and / or the Kentakt system.
Bei dem erfindungsgemäßen Relais werden also im Vergleich zu den Gesamtabmessuπgen des Relais sehr große Isolierstrecken zwischen den Kontaktelementen und dem Magnetsystem dadurch ge¬ schaffen, daß das Betätigungsorgan mit einer trog- oder wannen- förmigen Gestaltung entweder das Kontaktsystem oder das Magnet¬ system oder auch beide umschließt. Das Betätigungsorgan bzw. der betreffende Teil besitzt also im ersteren Fall einen U-för- migen Querschnitt. Im letzteren Fall, der besonders vorteilhaft ist und besonders lange Isolierstrecken gewährleistet, besitzt das Betätigungsorgan einen H-förmigen Querschnitt. Durch diese Form einer Wanne oder einer Doppelwanne ist das Betätigungsor¬ gan auch sehr stabil gegen Deformationen, so daß es auch ohne zusätzliche Verstärkungsrippen die Ankerbewegung exakt auf das Kontaktsystem übertragen kann.In the relay according to the invention, very large insulating distances between the contact elements and the magnet system are thus created in comparison to the overall dimensions of the relay in that the actuating member with a trough-shaped or trough-shaped design either the contact system or the magnet system or both encloses. The actuator or the part in question therefore has a U-shaped cross section in the former case. In the latter case, which is particularly advantageous and ensures particularly long insulating distances, the actuator has an H-shaped cross section. Through this In the form of a tub or a double tub, the actuator is also very stable against deformation, so that it can transmit the armature movement exactly to the contact system even without additional reinforcing ribs.
Die Erfindung ist deshalb mit besonderem Vorteil auf ein Relais anwendbar, dessen Magnetsystem den Aufbau eines herkömmlichen Winkelankersystems besitzt, wobei die winkelförmige Ankerein¬ heit jedoch nicht mehr vollständig aus Metall besteht. Vielmehr wird dabei der ferromagnetische, im wesentlichen plattenförmige Anker so mit dem Betätigungsorgan verbunden, daß das Betäti¬ gungsorgan den zweiten Schenkel der Winkelankereinheit bildet. Der plattenförmige Anker selbst kann von den. isolierenden Betä¬ tigungsorgan mehr oder weniger umschlossen sein, wobei ledig- lieh sichergestellt werden muß, daß der ferromagnetische Anker eine freie Polfläche gegenüber der "Kernpolfläche aufweist. Die Verbindung zwischen dem ferromagnetischen Ankerteil und dem Be- tätigungsorgan kann als Steckverbindung, besser jedoch als Kle¬ beverbindung oder insbesondere als Einbettung ausgebildet sein. In einer besonderen Ausführungsform kann das Betätigungselement bzw. die als Betätigungselement und Anker gebildete Ankerein- heit über den Anker an dem Joch gelagert sein.The invention is therefore particularly advantageously applicable to a relay whose magnet system has the structure of a conventional angle armature system, but the angular armature unit is no longer made entirely of metal. Rather, the ferromagnetic, essentially plate-shaped armature is connected to the actuating member in such a way that the actuating member forms the second leg of the angle armature unit.

In den Unteransprüchen sind noch weitere Ausgestaltungen des erfindungsgemäßen Relais genannt.Further embodiments of the relay according to the invention are mentioned in the subclaims.
Nachfolgend wird die Erfindung an einem Ausführungsbeispiel an¬ hand der Zeichnung näher erläutert. Es zeigenThe invention is explained in more detail below using an exemplary embodiment with reference to the drawing. Show it

Das in den Figuren 1 bis 5 gezeigte Relais besitzt ein Gehäuse 1 in Form einer Schutzkappe, deren offene Seite nach unten, al¬ so zur Einbauebene des Relais weist. Im oberen Bereich, also im geschlossenen Teil des Gehäuses 1, ist ein Magnetsystem ange¬ ordnet, bestehend aus einer Spulenwickluπc 2 auf einem Spulen- körper 3, einem axial αurch die Spule verlaufenden Kern 4 und einem winkelförmigen Joch 5, welches mit einem senkrecht ver¬ laufenden Schenkel 51 mit dem Kern 4 verbunden ist und sich mit einem waagerecht unterhalb der Spule verlaufenden Schenkel 52 parallel zur Spulenachse und zur Achse des Kerns erstreckt. Das freie Ende des Kerns 4 bildet eine Polplatte 41, welcher ein Anker 6 in Form einer ferromagnetischen Platte gegenübersteht.The relay shown in Figures 1 to 5 has a housing 1 in the form of a protective cap, the open side of which faces downward, thus towards the installation level of the relay. In the upper area, that is to say in the closed part of the housing 1, there is a magnet system consisting of a coil winding 2 on a coil body 3, an core 4 running axially through the coil and an angular yoke 5 which is connected to a vertically ver ¬ current leg 51 is connected to the core 4 and extends parallel to the axis of the coil and the axis of the core with a leg 52 extending horizontally below the coil. The free end of the core 4 forms a pole plate 41 which is opposed by an armature 6 in the form of a ferromagnetic plate.
Der Anker 6 ist mit einem Betätigungsorgan 7 zu einer festen Aπkereinheit verbunden. Dabei ist der Anker 6 in eine Seiten- wand 71 des Betätigungsorgans eingebettet oder eingeklebt, der¬ art, daß im wesentlichen nur die Polfläche 61, der Kernpolplat¬ te 41 gegenüberliegend, freiliegt. Für die Verbindung zwischen Anker und Betätigungsorgaπ sind natürlich auch andere Befesti¬ gungsverfahren, wie Ultraschallverschweißen und dergleichen, anwendbar. Die Seitenwand 71 des Betatigungsorgans 7 setzt sich , in eine umlaufende Wand 72 fort und bildet damit eine nach oben offene, das Magnetsystem teilweise umschließende Wanne 73. Au¬ ßerdem bildet das Betätigungsorgan auch zur Unterseite hin eine umlaufende Wand 74, welche somit eine nach unten offene Wanne 75 bildet, die ein Kontaktsystem 8 teilweise umschließt. Beide Wannen 75 und 73 sind durch einen gemeinsamen Boden bzw. eine Trennwand 16 gegeneinander abgegrenzt, wodurch das Kontaktsy¬ stem 8 von der Spule und vom Joch isoliert ist. Die Trennwand 16 verläuft im wesentlichen parallel zur Spulenachse und senk- recht zum Anker 6. Sie bildet somit den zweiten Schenkel einer aus dem Anker 6 und dem Betätigungsorgan 7 gebildeten Winkelan- kereiπheit. Durch die umlaufenden Seitenwände 72 und 74 ist das Betätigungsorgaπ auch genügend versteift, so daß es sich bei Betätigung nicht durchbiegt. Die Seitenwände 72 und 74 ergeben außerdem im Vergleich zu den Gesamtabmessungen des Relais sehr lange Luft- und Kriechstrecken zwischen dem Kontaktsystem 8 und der Spule 2 bzw. auch den metallischen Teilen des Magnetkrei¬ ses. Das Kontaktsystem ist im vorliegenden Fall auf einem isolieren¬ den Träger 81 aufgebaut, der einstückig aus einem plattenförmi¬ gen Sockelteil 82, einem Befestigungsblock 83 und einem Deckel¬ teil 84 besteht. In den Befestigungsblock 83 sind von beiden Seiten jeweils Aufnahmeschlitze 85 eingeformt (in Figur 6 nur an einer Seite zu sehen), in welche eine' Kontaktfeder 91 mit einem gefalteten Befestigungsteil 92 sowie eine Gegenkontaktfe- der 93 mit einem gefalteten Befestigungsteil 94 eingesteckt sind. Jedes der Kontaktelemente 91 und 93 besitzt einen durch Faltung des Federblechs gebildeten Anschlußstachel 95 bzw. 56. Durch das Falten erhält der Befestigungsteil 92 bzw. 94 jeweils die für die Steckbefestigung erforderliche Dicke und Stabili¬ tät, wobei die übereinander liegenden Abschnitte nach Bedarf auch durch eine Schweißuπg 98 verbunden sein können. Der umge- bogene Abschnitt bildet außerdem jeweils eine überstehende Kan¬ te 99. an der ein Moπtagewefrkzeug' zum Einpressen des jeweiligen Kontaktelementes 91 bzw. 93 in den Träger 81 angesetzt werden kann.The armature 6 is connected to an actuator 7 to form a fixed armature unit. The armature 6 is embedded or glued into a side wall 71 of the actuating member such that essentially only the pole face 61, opposite the core pole plate 41, is exposed. Of course, other fastening methods, such as ultrasonic welding and the like, can also be used for the connection between the armature and the actuating element. The side wall 71 of the actuating member 7 continues into a circumferential wall 72 and thus forms an upwardly open trough 73 which partially encloses the magnet system. In addition, the actuating member also forms a circumferential wall 74 on the underside, which is therefore a downward one forms open tub 75, which partially encloses a contact system 8. Both troughs 75 and 73 are delimited from one another by a common floor or a partition 16, as a result of which the contact system 8 is insulated from the coil and from the yoke. The partition 16 runs essentially parallel to the coil axis and perpendicular to the armature 6. It thus forms the second leg of an angular armature unit formed from the armature 6 and the actuating member 7. Due to the circumferential side walls 72 and 74, the actuating organ is also stiffened sufficiently so that it does not bend when actuated. The side walls 72 and 74 also result in very long air and creepage distances between the contact system 8 and the coil 2 and also the metallic parts of the magnetic circuit compared to the overall dimensions of the relay. In the present case, the contact system is constructed on an insulating carrier 81, which consists in one piece of a plate-shaped base part 82, a fastening block 83 and a cover part 84. In the mounting block 83 receiving slots 85 (in Figure 6 to see only one side) from both sides are each formed, in which a 'contact spring 91 with a folded fixing part 92 and a Gegenkontaktfe- the are inserted 93 with a folded fastening part 94th Each of the contact elements 91 and 93 has a connecting pin 95 or 56 formed by folding the spring plate. Folding gives the fastening part 92 or 94 the thickness and stability required for the plug-in fastening, the sections lying one above the other also being necessary as required a weld 98 can be connected. The vice-bent portion also forms respectively te 99 on which a Moπtagewefrkzeug 'for press-fitting of the respective contact element can be attached 91 and 93 in the carrier 81 is a protruding Kan¬.
Die Kontaktfeder 91 ist aoßerhalb ihrer Einspannstelle frei be¬ weglich. An ihrem freien Ende 97 wird sie über einen Betäti gungspimpel 77 oes Betätigungsorgans 7 entsprechend der Schalt- bewegung des Ankers betätigt. Der Deckelteil 84 des Trägers 81 bildet eine zusätzliche Isolierwand zwischen dem Kontaktsystem und dem Magnetsystem, wobei lediglich das freie Ende 97 derThe contact spring 91 is freely movable outside of its clamping point. At its free end 97, it is actuated via an actuation pimping device 77 or actuator 7 in accordance with the switching movement of the armature. The cover part 84 of the carrier 81 forms an additional insulating wall between the contact system and the magnet system, only the free end 97 of the
Kontaktfeder 91 zum Zwecke αer Betätigung vorsteht. Soweit eine dritte Isolierschicht zusätzlich zu der Trennwand 76 und dem Deckelteil 84 erforderlich ist, kann auf letzteres eine zusätz¬ liche Folie 86 aufgelegt bzw.. aufgeklebt werden, wie sie in Fi- gur 1 angedeutet, in Figur 6 jedoch nicht gezeigt ist.Contact spring 91 protrudes for the purpose of actuation. If a third insulating layer is required in addition to the dividing wall 76 and the cover part 84, an additional film 86 can be placed or glued onto the latter, as indicated in FIG. 1, but is not shown in FIG. 6.
Wenn der Deckelteil 84 aus Funktionsgründen kleiner ausgeführt werαen muß, ist es zweckmäßig, eine oder mehrere Folien auf die Trennwand 76 aufzubringen. Auch ist es möglich, die Trennwand 76 durch Zwischenräume so zu gestalten, daß mindestens drei Isolierwände entstehen. Anstelle des im Beispiel gezeigten einen Schließers kann natür¬ lich auch ein beliebiger anderer Federsatz in dem Relais ver¬ wendet werden, beispielsweise ein Öffner, ein Umschalter oder auch ein Federsatz mit mehreren Einheiten.If the cover part 84 has to be made smaller for functional reasons, it is expedient to apply one or more foils to the partition 76. It is also possible to design the partition 76 by spaces so that at least three insulating walls are formed. Instead of the one closer shown in the example, any other spring set can of course also be used in the relay, for example an opener, a changeover switch or a spring set with several units.
Bei der Montage des Relais wird zunächst die komplette Anker¬ einheit, bestehend aus dem Anker 6 und dem Betätigungsorgan 7, auf das Magnetsystem aufgesetzt, wobei eine am Anker angeformte Lagerschneide 62 in eine Lagerkerbe 5.3 des Joches eingesetzt wird. Dieses damit komplettierte Magnetsystem wird dann in das Gehäuse 1 eingeschoben, wobei die Spule, bestehend aus Wicklung 2 und Spulenkörper 3, verzugsweise im geschlossenen Endteil des Gehäuses 1 festgeklemmt bzw. festgeklebt wird. Die Ankereiπheit wird αamit durch die Seitenwand 11 des Gehäuses 1 gegen Heraus- fallen gesichert.When installing the relay, the complete armature unit, consisting of the armature 6 and the actuating member 7, is first placed on the magnet system, with a bearing edge 62 formed on the armature being inserted into a bearing notch 5 . 3 of the yoke is used. This completed magnet system is then pushed into the housing 1, the coil, consisting of winding 2 and coil body 3, being clamped or glued in the closed end part of the housing 1. The anchor unit is thus secured against falling out by the side wall 11 of the housing 1.
In die offene Seite αes Gehäuses 1 wird dann das Kontaktsystem 8 eingesetzt, wobei der abgesetzte Randbereich 12 des Gehäuses eine Geradführung für den Sockel 82 des Kontaktsystems bildet. Der Außenrand 82a dieses Sockels 82 ist weitgehend an die Kon¬ tur des Gehäuserandes 12 angepaßt; er besitzt jedoch einige Ausnehmungen zur Durchführung der Kontakt-Anschlußstachel 95 und 96 sowie der Isolierummantelung 31 der Spulenanschlußstifte 10. Der Sockel 82 wird beim Einschieben nicht gegen einen An- schlag αes Gehäuses gefünrt, sondern bei erregtem Magnetsystem soweit eingeschoben, bis die Kontaktfeder 91 durch den Pimpel 77 betätigt und der Kontakt mit αem Gegenkontaktelement 93 ge¬ schlossen wird. Danach wird die Erregung des Relais abgeschal¬ tet, so daß sich der Kontakt öffnet. Das Kontaktsystem 8 wird nunmehr zusätzlich um einen vorgegebenen Betrag eingeschoßen, mit dem eine bestimmte Abbrandsicherheit der Kontakte gewähr¬ leistet wird. Danach wird das Kontaktsystem, also der Sockel 82, gegenüber dem Gehäuse fixiert, was beispielsweise mittels eines Schnellklebers geschehen kann.The contact system 8 is then inserted into the open side of the housing 1, the offset edge region 12 of the housing forming a straight guide for the base 82 of the contact system. The outer edge 82a of this base 82 is largely adapted to the contour of the housing edge 12; However, it has some recesses for carrying out the contact pin 95 and 96 and the insulating jacket 31 of the coil connector pins 10. The base 82 is not opened when inserted against a stop αes housing, but inserted so far when the magnet system is excited until the contact spring 91 through the Pimpel 77 is actuated and the contact with the counter-contact element 93 is closed. Then the excitation of the relay is switched off, so that the contact opens. The contact system 8 is now additionally injected by a predetermined amount, with which a certain erosion safety of the contacts is guaranteed. The contact system, that is to say the base 82, is then fixed relative to the housing, which can be done, for example, by means of a quick adhesive.
Zur Abdichtung der verbleibenden Öffnungen im Boden wird eine Abdeckplatte 13 über die Aπschlußstifte 95, 96 und 10 gescho- ben. In dem durch die Abdeckplatte 13 und den Gehäuserand 12 gebildeten Raum wird dann von außen Vergußmasse 14 eingebracht, womit die Abdichtung des Gehäuses vollendet wird. Dabei kann natürlich in üblicher Weise im Gehäuse ein Lüftungsloch vorge¬ sehen sein, welches während oder auch nach der Abdichtung ge¬ öffnet und später verschlossen wird. To seal the remaining openings in the floor, a cover plate 13 is closed over the connecting pins 95, 96 and 10. ben. Potting compound 14 is then introduced into the space formed by the cover plate 13 and the housing edge 12, thus completing the sealing of the housing. Of course, a ventilation hole can be provided in the housing in the usual way, which is opened during or after the sealing and is later closed.
