Definitions
- the invention relates to a small switching relay with increased insulation between the magnet system and the contact system for use as a miniature card relay according to the preamble of claim 1.
- Another known relay according to DE-B-2 717 293 provides for a receptacle for the free, pivotable end of the armature in a pocket of the actuation t eges, but otherwise does not take any measures for resistance to creep or high voltage, in particular between the contact system and the magnet system to increase.
- the object of the present invention is therefore to develop a relay of the type mentioned in such a way that increased resistance to creepage distances is achieved.
- the essence of the invention is that the armature, the armature retaining spring and the magnet system are at least partially encompassed by a rib or by their angling, so that the high-voltage strength of the relay is increased in the manner of a partition wall against leakage currents. Furthermore, the actuating web is also formed at one end as a pocket which engages around the free end of the armature, so that creeping distances starting from the contact system are thereby suppressed.
- the present relay also has clearance and creepage distances of more than 8 mm in the version with a changeover contact. H. so increased isolation. So far, such relays with larger dimensions were only known in the version with a normally open contact.
- the relay is designed so that the washproof version (IP 67) has the same dimensions as the open version (IP 40).
- the present relay only has a height of 7.9 mm, which comes about as follows:
- the spring bracket is formed in one piece with the housing trough which is open on one side results in a desired miniaturization despite the high voltage strength.
- the spring bracket is the mounting element for all parts of the relay, in particular the contact system and the magnet system.
- the housing is preferably made of a plastic injection molding material, so that the contact system and the magnet system are inserted directly into the housing and fastened there. The pre-assembly outside the housing with corresponding mounting elements is not necessary, since these separate mounting elements would only take up space in an undesirable manner.
- the magnetic frame is installed by simply inserting the excitation coil with core and yoke into the housing, the armature retaining spring being fastened in a holder fixed to the housing. All parts are only protected against falling out by the cover. In order to reach the 8 mm clearance and creepage distances, the anchor must be embedded in a pocket on the actuation bar.
- the overall construction thus enables automated production.
- the relay is a real miniature switching relay with increased insulation between the coil and contacts. It is used wherever PCB spacing and module widths do not allow wider relays without having to do without the characteristic features of a small switching relay. It is primarily developed on the basis of VDE 0110, VDE 0435, VDE 0631, VDE 0660, VDE 0730, VDE 0804 and VDE 860.
- the relay according to FIGS. 1 to 4 has a housing trough 10 which also serves as a spring bracket 1 for holding the magnet system 2 and the contact system 3.
- the magnet system 2 comprises an excitation coil in which the yoke and core 8 are formed from a single U-shaped part in a stamping and bending process.
- the entire magnet system 2 is only inserted into the housing trough, with the connections 27 reaching through corresponding lateral slots in the housing trough.
- the magnet system is essentially protected from falling out by the cover 4, which is pressed onto the housing trough.
- a further securing of the position of the magnet system 2 results from the fact that an armature retaining spring 11 is present, which is clamped in the slot 21 of a holder 12.
- the holder 12 is formed in one piece with the bottom of the housing trough 10.
- the armature retaining spring forms the abutment for the L-shaped armature 13 pivotably mounted on the yoke 8. The end of the long leg of this armature is received by a pocket 14 of the actuating web 15. This is done for insulation reasons.
- the actuating web 15 passes through a narrow opening 19 in the chamber wall 17, which separates the magnet system 2 from the contact system 3 arranged above it.
- the contact system 3 has two switching springs 7a, 7b which, depending on the position of the armature 13, come into alternating contact with the contact spring 7c.
- the switching springs 7a, 7b are accommodated in corresponding slots 22, 23 of the housing, a plurality of slots 22 and 23 lying one behind the other being provided which are each separated by a recess 25.
- the contact spring 7c is also guided in a slot 24 of the housing 10 and also passes through a recess 26. The position of the springs 7a, 7b, 7c is then secured in the region of the recesses 25, 26.
- the springs 7a, 7b, 7c are guided to the outside with connecting lugs 9a, 9b, 9c, it being essential that the connecting lugs pass through the cover 4 in the lying embodiment and the cover is equipped with conically tapering openings 5 in the area of the connecting lugs, and has pockets 28 of recessed diameter on the outside.
- a rib 16 is formed on the underside of the cover 4, which abuts directly on the chamber wall 17 and thus ensures a double separation of the contact system 3 and the magnet system 2. According to FIG. 2, the rib 16 extends close to the bottom of the housing trough 10.
- the rib 16 is provided with an angled portion 20, which still partially encompasses the excitation coil of the magnet system 2 and overlaps the armature holding spring 11.

Description
Die Erfindung betrifft ein Kleinschaltrelais mit erhöhter Isolation zwischen Magnetsystem und Kontaktsystem zur Verwendung als Miniatiur-Kartenrelais nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a small switching relay with increased insulation between the magnet system and the contact system for use as a miniature card relay according to the preamble of
Ein derartiges Relais ist aus der EP-A-0 049 088 bereits bekannt. Bei dieser bekannten Anordnung sind zwar im Bereich des Betätigungssteges Trennwände vorgesehen, die aber das Magnetsystem, den Anker und die Ankerhaltefeder nicht weiter umgreifen. Hierdurch könnte wegen sich bildender Kriechstrecken die Hochspannungsfestigkeit des Relais beeinträchtigt werden.Such a relay is already known from EP-A-0 049 088. In this known arrangement, partitions are provided in the area of the actuating web, but these do not encompass the magnet system, the armature and the armature retaining spring. This could impair the high-voltage strength of the relay due to creepage distances that form.
Ein weiteres bekanntes Relais nach der DE-B-2 717 293 sieht zwar eine Aufnahme des freien, schwenkbaren Endes des Ankers in einer Tasche des Betätigungssteges vor, trifft sonst aber keine Maßnahmen um die Kriech- oder Hochspannungsfestigkeit, insbesondere zwischen Kontaktsystem und Magnetsystem zu erhöhen.Another known relay according to DE-B-2 717 293 provides for a receptacle for the free, pivotable end of the armature in a pocket of the actuation t eges, but otherwise does not take any measures for resistance to creep or high voltage, in particular between the contact system and the magnet system to increase.
Die Aufgabe der vorliegenden Erfindung ist es deshalb, ein Relais der eingangs genannten Art so weiterzubilden, daß eine erhöhte Festigkeit gegen Kriechstrecken erreicht wird.The object of the present invention is therefore to develop a relay of the type mentioned in such a way that increased resistance to creepage distances is achieved.
Die Lösung der gestellten Aufgabe ist durch die Merkmale des kennzeichnenden Teiles des Patentanspruchs 1 angegeben.The solution to the problem is given by the features of the characterizing part of
Das Wesen der Erfindung liegt darin, daß der Anker, die Ankerhaltefeder und das Magnetsystem zumindest teilweise von einer Rippe bzw. von deren Abwinklung umfaßt werden, so daß gegenüber Kriechströmen die Hochspannungsfestigkeit des Relais nach Art einer Trennwand gesteigert wird. Weiterhin ist auch der Betätigungssteg an einem Ende als Tasche ausgebildet, die das freie Ende des Ankers umgreift, so daß hierdurch Kriechstrecken ausgehend vom Kontaktsystem unterdrückt werden.The essence of the invention is that the armature, the armature retaining spring and the magnet system are at least partially encompassed by a rib or by their angling, so that the high-voltage strength of the relay is increased in the manner of a partition wall against leakage currents. Furthermore, the actuating web is also formed at one end as a pocket which engages around the free end of the armature, so that creeping distances starting from the contact system are thereby suppressed.
Das vorliegende Relais besitzt auch in der Ausführung mit einem Wechselkontakt Luft- und Kriechstrecken von mehr als 8 mm, d. h. also verstärkte Isolation. Bisher waren solche Relais mit größeren Abmessungen nur in der Ausführung mit einem Arbeitskontakt bekannt.The present relay also has clearance and creepage distances of more than 8 mm in the version with a changeover contact. H. so increased isolation. So far, such relays with larger dimensions were only known in the version with a normally open contact.
Das Relais ist so konzipiert, daß auch die waschdichte Ausführung (IP 67) die gleichen Abmessungen trägt, wie die offene Ausführung (IP 40).The relay is designed so that the washproof version (IP 67) has the same dimensions as the open version (IP 40).
Das vorliegende Relais erreicht lediglich eine Bauhöhe von 7,9 mm, die wie folgt zustande kommt:The present relay only has a height of 7.9 mm, which comes about as follows:
1/2-Zoll-Abstand (12,7 mm) Leiterplatte zu Leiterplatte, übliche Leiterplattendicke von 1,5 - 3,2 mmm, Bauhöhe Relais 7,9 mm lassen noch Stiftlängen auf der Rückseite der Leiterplatten zum Einlöten von 1,6 mm zu. Diese Stiftlänge ist üblicherweise für eine gute Schwallbadlötung erforderlich.1/2-inch distance (12.7 mm) PCB to PCB, usual PCB thickness of 1.5 - 3.2 mm, height relay 7.9 mm still leave pin lengths on the back of the PCB for soldering 1.6 mm to. This pin length is usually required for good wave soldering.
Dadurch, daß der Federbock werkstoffeinstückig mit der einseitig offenen Gehäusewanne gebildet ist, ergibt sich trotz Hochspannungsfestigkeit eine erwünschte Miniaturisierung. Der Federbock ist im herkömmlichen Sprachgebrauch das Halterungselement für sämtliche Teile des Relais, insbesondere des Kontaktsystems und des Magnetsystems. Das Gehäuse wird vorzugsweise aus einem Kunststoff-Spritzgußmaterial hergestellt, so daß das Kontaktsystem und das Magnetsystem unmittelbar in das Gehäuse eingesetzt und dort befestigt werden. Die Vormontage außerhalb des Gehäuses mit entsprechenden Halterungselementen entfällt, denn diese separaten Halterungselemente würden nur in unerwünschter Weise Platz beanspruchen.The fact that the spring bracket is formed in one piece with the housing trough which is open on one side results in a desired miniaturization despite the high voltage strength. In conventional language, the spring bracket is the mounting element for all parts of the relay, in particular the contact system and the magnet system. The housing is preferably made of a plastic injection molding material, so that the contact system and the magnet system are inserted directly into the housing and fastened there. The pre-assembly outside the housing with corresponding mounting elements is not necessary, since these separate mounting elements would only take up space in an undesirable manner.
Die Montage des Magnetgestells erfolgt durch einfaches Einschieben der Erregerspule mit Kern und Joch in das Gehäuse, wobei die Ankerhaltefeder in einer gehäusefesten Halterung befestigt ist. Alle Teile werden nur durch den Deckel gegen Herausfallen geschützt. Um die 8-mm Luft- und Kriechstrecken zu erreichen, muß der Anker in einer Tasche des Betätigungssteges eingebettet werden.The magnetic frame is installed by simply inserting the excitation coil with core and yoke into the housing, the armature retaining spring being fastened in a holder fixed to the housing. All parts are only protected against falling out by the cover. In order to reach the 8 mm clearance and creepage distances, the anchor must be embedded in a pocket on the actuation bar.
Die Gesamtkonstruktion lässt damit eine automatisierte Fertigung zu.The overall construction thus enables automated production.
Nachfolgend werden die technischen Daten des erfindungsgemässen Kleinschaltrelais wiedergegeben:The technical data of the small switching relay according to the invention are shown below:
Das Relais ist ein echtes Kleinschaltrelais mit erhöhter Isolation zwischen Spule und Kontakten. Es findet überall dort Einsatz, wo Leiterplattenabstände und Modulbreiten keine breiteren Relais zulassen, ohne daß dabei auf die charakteristischen Merkmale eines Kleinschaltrelais verzichtet werden muß. Es ist vor allem entwickelt auf der Basis von VDE 0110, VDE 0435, VDE 0631, VDE 0660, VDE 0730, VDE 0804 und VDE 860.The relay is a real miniature switching relay with increased insulation between the coil and contacts. It is used wherever PCB spacing and module widths do not allow wider relays without having to do without the characteristic features of a small switching relay. It is primarily developed on the basis of VDE 0110, VDE 0435, VDE 0631, VDE 0660, VDE 0730, VDE 0804 and VDE 860.

Das Relais nach den Figuren 1 bis 4 hat eine Gehäusewanne 10, die gleichzeitig als Federbock 1 für die Halterung des Magnetsystems 2 und des Kontaktsystems 3 dient.The relay according to FIGS. 1 to 4 has a
Das Magnetsystem 2 umfaßt eine Erregerspule, bei der Joch und Kern 8 aus einem einzigen U-förmigen Teil in einem Stanzbiegevorgang geformt sind.The
Das gesamte Magnetsystem 2 ist in die Gehäusewanne nur eingelegt, wobei die Anschlüsse 27 entsprechende seitliche Schlitze der Gehäusewanne durchgreifen. Das Magnetsystem wird im wesentlichen durch den rastend auf die Gehäusewanne aufgedrückten Deckel 4 vor dem Herausfallen geschützt. Eine weitere Lagensicherung des Magnetsystems 2 ergibt sich dadurch, daß eine Ankerhaltefeder 11 vorhanden ist, die in den Schlitz 21 einer Halterung 12 eingeklemmt ist. Die Halterung 12 ist hierbei gemäss Figur 2 werkstoffeinstückig mit dem Boden der Gehäusewanne 10 ausgebildet. Die Ankerhaltefeder bildet das Widerlager für den schwenkbar auf das Joch 8 aufgesetzten L-förmigen Anker 13. Das Ende des langen Schenkels dieses Ankers wird von einer Tasche 14 des Betätigungssteges 15 aufgenommen. Dies wird aus Isolationsgründen vorgenommen. Der Betätigungssteg 15 durchgreift einen schmalen Durchbruch 19 in der Kammerwand 17, welche das Magnetsystem 2 von dem darüber angeordneten Kontaktsystem 3 trennt. In der gezeigten Ausführungsform hat das Kontaktsystem 3 zwei Schaltfedern 7a, 7b, die je nach Stellung des Ankers 13 abwechselnd in Berührung mit der Kontaktfeder 7c kommen.The
Die Schaltfedern 7a, 7b sind in entsprechenden Schlitzen 22,23 des Gehäuses aufgenommen, wobei mehrere, hintereinanderliegende Schlitze 22 bzw. 23 vorgesehen sind, die durch jeweils eine Ausnehmung 25 getrennt sind.The switching springs 7a, 7b are accommodated in corresponding
Die Kontaktfeder 7c ist gleichfalls in einem Schlitz 24 des Gehäuses 10 geführt und durchgreift auch eine Ausnehmung 26. Im Bereich der Ausnehmungen 25, 26 erfolgt dann die Lagensicherung der Federn 7a, 7b, 7c.The contact spring 7c is also guided in a
Die Federn 7a, 7b, 7c sind mit Anschlußfahnen 9a, 9b, 9c nach außen geführt, wobei wesentlich ist, daß bei der liegenden Ausführung die Anschlußfahnen durch den Deckel 4 hindurchgehen und der Deckel im Bereich der Anschlußfahnen mit konisch zulaufenden Durchbrüchen 5 ausgestatet ist, und auf der Außenseite Taschen 28 vertieften Durchmessers aufweist.The
Durch die Anordnung von konischen Durchbrüchen 5 werden zunächst Fließhäute im Bereich des Durchtritts der Anschlußfahnen 9 durch die entsprechende Ausnehmung im Deckel 4 durchstoßen, worauf sich diese Fließhäute abdichtend um den Anschluß 9 herumlegen. Es wird damit vermieden, daß bei der Verklebung der Anschlüsse 9 mit dem Deckel 4 Material in das Innere des Relais hineinläuft. Die Taschen 28 sind über entsprechende Zwischenbahnen alle miteinander verbunden, so daß durch Eingabe von Klebstoff in eine einzige Tasche der Klebstoff sich in den Bahnen verteilt, und in alle anderen Taschen 28 hineinläuft, und damit mit einer einzigen Klebstoff-Zugabe alle Anschlußfahnen 9 mit dem Deckel 4 verklebt werden.Through the arrangement of
In den Figuren 1, 3 und 4 ist noch als Alternative gezeigt, daß anstatt der Anschlußfahnen 9 entsprechende Anschlußstifte 6 für eine stehende Ausführung vorgesehen sein können, die dann durch eine Seitenwand der Gehäusewanne 10 hindurchgreifen.In Figures 1, 3 and 4 it is shown as an alternative that instead of the connecting
An der Unterseite des Deckels 4 ist eine Rippe 16 angeformt, die unmittelbar an der Kammerwand 17 anliegt und damit eine doppelte Trennung von Kontaktsystem 3 und Magnetsystem 2 gewährleistet. Die Rippe 16 erstreckt sich gemäss Figur 2 bis nahe an den Boden der Gehäusewanne 10.A
Um den Anker 13 ausreichend zu isolieren, ist die Rippe 16 mit einer Abwinklung 20 versehen, welche noch zum Teil die Erregerspule des Magnetsystems 2 umfasst und die Ankerhaltefeder 11 übergreift.In order to adequately isolate the
Durch die Anordnung sämtlicher Befestigungselemente für Magnetsystem 2 und Kontaktsystem 3 in einer Gehäusewanne, wobei sämtliche Halterungselemente (des Federbocks 1) werkstoffeinstückig mit der Wanne 10 ausgebildet sind, ergibt sich eine vorteilhafte Miniaturisierung.The arrangement of all the fastening elements for the
