Description

Die Erfindung betrifft ein Kleinschaltrelais mit erhöhter Isolation zwischen Magnet-System und Kontaktsystem zur Verwendung als Miniatur-Karten-Relais, bestehend aus einem Federbock, Magnet- und Kontaktsystem aufnehmenden Gehäuse und einem das Gehäuse abschließenden Deckel.The invention relates to a small switching relay with increased insulation between the magnet system and contact system for use as a miniature card relay, consisting of a spring bracket, magnet and contact system receiving housing and a cover closing the housing.

Ein eingangs genanntes Kleinschaltrelais wird in mehreren Ausführungsformen hergestellt. Nachteil aller bekannten Ausführungsformen ist, daß bestimmte Mindestabmessungen nicht unterschritten werden können. Herkömmliche Außenabmessungen sind beispielsweise 27,9 x 24,7 x 10,4 mm. Eine Unterschreitung dieses Maßes war bisher nicht möglich, weil man einerseits eine erhöhte Isolation anstrebte und andererseits wegen der Isolierungsmaßnahmen und aus Konstruktionsgründen das Kontaktsystem mit den Halterungen für die Kontaktfeder getrennt vom Gehäuse herstellte.A small switching relay mentioned at the outset is produced in several embodiments. The disadvantage of all known embodiments is that certain minimum dimensions cannot be undershot. Conventional external dimensions are, for example, 27.9 x 24.7 x 10.4 mm. So far, it was not possible to go below this dimension because, on the one hand, increased insulation was sought and, on the other hand, because of the insulation measures and for constructional reasons, the contact system with the holders for the contact spring was produced separately from the housing.

Die vorliegende Erfindung hat sich die Aufgabe gestellt, ein Kleinschaltrelais der eingangs genannten Art so weiterzubilden, daß es als Karten-Relais verwendbar ist, und beispielsweise im 5-mm-Raster nebeneinander montiert werden kann.The present invention has for its object to develop a small switching relay of the type mentioned so that it can be used as a card relay, and can be mounted next to each other, for example, in a 5 mm grid.

Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß der Federbock werkstoffeinstückig mit dem als einseitig offenen, wannenförmigen Gehäuse ausgebildet ist.To achieve the object, the invention is characterized in that the spring bracket is made of one piece of material with the trough-shaped housing which is open on one side.

Merkmal der Erfindung ist, daß ein wannenförmiger Federbock vorhanden ist, in dem ein darin abgekammertes Magnetsystem und ein ebenfalls abgekammertes Kontaktsystem angeordnet sind. Den Abschluß bildet ein Deckel, der rastend gehalten wird.It is a feature of the invention that a trough-shaped spring bracket is present, in which a spring-loaded bracket Magnet system and a chambered contact system are also arranged. The end is a lid that is held in place.

Wegen der durch Elektronikbauteile vorgegebenen Bauteilhöhe und der 1/2-Zoll-Abstands-Karten-Einschubtechnik wurde für dieses Relais in liegender Ausführung eine maximale Höhe von 7,9 mm erstmals unterschritten.Due to the component height specified by electronic components and the 1/2-inch distance card insertion technology, the maximum height for this relay in the horizontal version was 7.9 mm.

Dies bedeutet, daß das erfindungsgemässe Relais das erste Starkstrom-Kleinschalt-Relais in extrem flacher Ausführung ist.This means that the relay according to the invention is the first high-current small switching relay in an extremely flat design.

In stehender Ausführung kann dieses Relais im 5-mm-Raster nebeneinander ebenfalls als erstes Relais montiert werden.In the standing version, this relay can also be installed next to each other in a 5 mm grid as the first relay.

Im Gegensatz zu bekannten Relais besitzt das vorliegende Relais auch in der Ausführung 1 Wechsler Luft- und Kriechstrecken von mehr als 8 mm, d.h. also verstärkte Isolation. Bisher waren solche Relais mit größeren Abmessungen nur in der Ausführung 1 x Arbeit bekannt.In contrast to known relays, this relay also has 1 changer version with clearance and creepage distances of more than 8 mm, i.e. so increased isolation. So far, such relays with larger dimensions were only known in the 1 x work version.

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).

Es wird also als erfindungswesentlich die Kombination , bestehend aus einer Miniaturisierung bekannter Karten-relais mit den Sondermerkmalen der erhöhten Isolation (8 mm), der stehenden und liegenden Ausführung, der offenen und dichten Ausführung, beansprucht.The combination consisting of a miniaturization of known card relays with the special features of increased insulation (8 mm), the standing and lying version, the open and sealed version is claimed as essential to the invention.

Die erreichte Bauhöhe von 7,9 mm kommt wie folgt zustande:

  • 1/2-Zoll-Abstand (12,7 mm) Leiterplatte zu Leiterplatte, übliche Leiterplattendicke von 1,5 - 3,2 mm, Bauhöhe Relais 7,9 mm lassen noch Stiftlängen auf der Rückseite der Leiterplatte zum Einlöten von 1,6 mm zu. Diese Stiftlänge ist üblicherweise für eine gute Schwallbadlötung erforderlich.
The overall height of 7.9 mm is achieved as follows:
  • 1/2-inch distance (12.7 mm) PCB to PCB, usual PCB thickness of 1.5 - 3.2 mm, relay height 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.

Mit dem Merkmal bedingt, daß der Federbock werkstoffeinstückig mit dem als einseitig offenen, wannenförmigen Gehäuse ausgebildet ist, ergibt sich die geforderte Miniaturisierung. Der Federbock ist im herkömmlichen Sprachgebrauch das Halterungselement für sämtliche Teile des Relais, insbesondere des Kontaktsystems und des Magnetsystem. Wenn nun der Federbock werkstoffeinstückig mit dem Gehäuse selbst ausgebildet ist, dann geht hieraus hervor, daß eine getrennte Anordnung von Halterungsteilen und Gehäusen nach der Erfindung vermieden wird und stättdessen die Halterungsteile im Gehäuse selbst integriert werden. Das Gehäuse wird vorzugsweise aus einem Kunststoff-Spritzgußmaterial hergestellt, so daß das Kontaktsystem und das Magnet- system unmittelbar in das Gehäuse eingesetzt und dort befestigt wird. Die Vormontage außerhalb des Gehäuses mit entsprechenden Halterungselementen entfällt, denn diese separaten Halterungselemente würden nur in unerwünschter Weise Platz beanspruchen.With the feature that the spring bracket is made in one piece with the trough-shaped housing that is open on one side, the required miniaturization results. 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. If the spring bracket is made of one piece of material with the housing itself, it can be seen from this that a separate arrangement of mounting parts and housings according to the invention is avoided and instead the mounting parts are integrated into the housing itself. The housing is preferably made from 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 in the actuating web.

Die Gesamtkonstruktion lässt damit eine automatisierte Fertigung zu.The overall construction thus enables automated production.

Das Relais nach den Figuren 1 bis 4 besteht aus einem wannenförmigen Gehäuse 10, was gleichzeitig als Federbock 1 für die Halterung des Magnetsystems 2 und das Kontaktsystem 3 dient.The relay according to Figures 1 to 4 consists of a trough-shaped housing 10, which also serves as a spring bracket 1 for holding the magnet system 2 and the contact system 3.

Das Magnetsystem 2 besteht aus einer Erregerspule, bei der Joch und Kern 8 aus einem einzigen Teil in einem Stanzbiegevorgang geformt sind und als U-förmiges Teil ausgebildet sind. Bezüglich der damit verbundenen Vorteile wird auf die auf den gleichen Anmelder zurückgehende deutsche Patentanmeldung P 33 24 246.1 verwiesen. Die Offenbarung dieser Patentanmeldung soll vollumfänglich von der hier vorliegenden Patentanmeldung umfasst und einbezogen sein.The magnet system 2 consists of an excitation coil, in which the yoke and core 8 are formed from a single part in a stamping and bending process and are designed as a U-shaped part. With regard to the associated advantages, reference is made to the German patent application P 33 24 246.1, which goes back to the same applicant. The disclosure of this patent application is to be encompassed and included in full by the present patent application.

Das gesamte Magnetsystem 2 ist nur in das Gehäuse eingelegt, wobei die Anschlüsse 27 entsprechende seitliche Schlitze am Gehäuse durchgreifen. Das Magnetsystem ist also nur in das Gehäuse eingelegt und wird im wesentlichen durch den rastend auf das Gehäuse aufgedrückten Deckel 4 vor dem Herausfallen geschützt. Eine weitere Lagensicherung des Magnetsystem 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 des Gehäuses 10 verbunden. Die Ankerhaltefeder bildet das Wiederlager für den schwenkbar auf das Joch 8 aufgesetzten Anker 13, dessen hinteres, freies und schwenkbares Ende in einer Tasche 14 des Betätigungssteges 15 aufgenommen ist. Dies wird aus Isolationsgründen vorgenommen. Der Betätigungssteg 15 durchgreift einen schmalen Durchbruch 19 in der Kammerwand 17, welche das Magnet- system 2 von dem darüber angeordneten Kontaktsystem 3 trennt. In der gezeigten Ausführungsform besteht das Kontaktsystem 3 aus zwei Schaltfedern 7a, 7b, die je nach Stellung des Ankers 13 in Berührung mit der Kontaktfeder 7c kommen.The entire magnet system 2 is only inserted into the housing, the connections 27 penetrating corresponding lateral slots on the housing. The magnet system is therefore only inserted into the housing and is essentially protected from falling out by the cover 4 which is pressed into place on the housing. 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. According to FIG. 2, the holder 12 is integrally connected to the bottom of the housing 10. The armature retaining spring forms the abutment for the armature 13 pivotably mounted on the yoke 8, the rear, free and pivotable end of which is received in 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. In the embodiment shown, the contact system 3 consists of two switching springs 7a, 7b which, depending on the position of the armature 13, come into contact with the contact spring 7c.

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 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.

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 likewise guided in a slot 24 in the housing 10 and also extends through a recess 26. The position of the springs 7a, 7b, 7c is then secured in the region of the recesses 25, 26.

Die Federn 7a, 7b, 7c sind mit Anschlüssen 9a, 9b, 9c nach außen geführt, wobei wesentlich ist, daß bei der liegenden Ausführung die Anschlüsse durch den Deckel 4 hindurchgehen und der Deckel im Bereich der Anschlüsse mit konisch zulaufenden Durchbrüchen 5 ausgestattet ist, und auf der Außenseite Taschen 28 vertieften Durchmessers aufweist. Hinsichtlich der Bedeutung der konischen Durchbrüche 5 und der Taschen 28 wird auf die auf den gleichen Anmelder zurückgehende deutsche Patentanmeldung P 33 19 329.0 verwiesen. Die dortige Offenbarung soll vollumfänglich von der hier stehenden Offenbarung umfasst und einbezogen werden.The springs 7a, 7b, 7c are led to the outside with connections 9a, 9b, 9c, it being essential that the connections pass through the cover 4 in the horizontal configuration and the cover is provided with conically tapering openings 5 in the area of the connections, and has pockets 28 of recessed diameter on the outside. With regard to the meaning of the conical openings 5 and the pockets 28, reference is made to the German patent application P 33 19 329.0, which goes back to the same applicant. The disclosure there is intended to be encompassed and included in full by the disclosure herein.

Wesentlich bei dieser Anordnung ist, daß durch die Anordnung von konischen Durchbrüchen 5 zunächst Fließhäute im Bereich des Durchtritts der Anschlüsse 9 durch die entsprechende Ausnehmung im Deckel 4 durchstoßen werden und 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 Anschlüsse 9 mit dem Deckel 4 verklebt werden.It is essential in this arrangement that, through the arrangement of conical openings 5, flow membranes in the region of the passage of the connections 9 are first pierced through the corresponding recess in the cover 4 and these flow membranes are sealed around the connection 9. It is thus avoided that material runs into the interior of the relay when the connections 9 are glued to the cover 4. The pockets 28 are all connected to one another via corresponding intermediate webs, so that the adhesive is distributed in the webs by entering adhesive in a single pocket, and runs into all other pockets 28, and thus all connections 9 with the single adhesive addition Cover 4 are glued.

In den Figuren 1, 3 und 4 ist noch als Alternative gezeigt, daß anstatt der Anschlüsse 9 entsprechende Anschlußstifte 6 für eine stehende Ausführung vorgesehen sein können, die dann durch eine Seitenwand des Gehäuses 10 hindurchgreifen.In Figures 1, 3 and 4 it is shown as an alternative that instead of the connections 9 corresponding pins 6 can be provided for a standing version, which then reach through a side wall of the housing 10.

Wichtig ist, daß an der Unterseite des Deckels 4 eine Rippe 16 angeformt ist, die unmittelbar an der Kammerwand 17 anliegt und damit eine doppelte Trennung von Kontaktsystem 3 zu Magnetsystem 2 gewährleistet. Wichtig ist ferner, daß sich die Rippe 16 bis nahe an den Boden des Gehäuses 10 gemäss Figur 2 erstreckt.It is important that 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 from the contact system 3 to the magnet system 2. It is also important that the rib 16 extends to close to the bottom of the housing 10 according to Figure 2.

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 armature 13, 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.

Durch die Anordnung sämtlicher Befestigungselemente für Magnetsystem 2 und Kontaktsystem 3 in einem Gehäuse, wobei sämtliche Halterungselemente (des Federbocks 1) werkstoffeinstückig mit dem Gehäuse 10 verbunden sind, ergibt sich die geforderte Miniaturisierung.The required miniaturization results from the arrangement of all fastening elements for magnet system 2 and contact system 3 in one housing, wherein all mounting elements (of the spring bracket 1) are integrally connected to the housing 10.
