Abstract
Description
Die Erfindung bezieht sich auf elektromagnetische Kleinstrelais, denen elektronische Bausteine oder Module schaltungstechnisch zugeordnet werden oder denen Schaltkreise beigeordnet sind, und folglich nächst einem solchen Relais untergebracht werden sollten.The invention relates to small electromagnetic relays to which electronic modules or modules are assigned in terms of circuitry or to which circuits are associated, and consequently should be accommodated next to such a relay.
Eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus der CA-A-117 30 86 bekannt.A device according to the preamble of
Die vorliegende Erfindung geht von an sich bekannten Relaiskonstruktionen aus, in denen die Bodenplatte aus isolierendem Material geformt ist und als Basis für den Aufbau des Relais mit Magnet- und Federkontaktsystem dient.The present invention is based on relay constructions known per se, in which the base plate is formed from insulating material and serves as the basis for the construction of the relay with a magnetic and spring contact system.
Dieser Erfindung lag nun die Aufgabe zugrunde, bei einem Kleinstrelais gemäß dem Oberbegriff des Anspruchs 1, auf einfache Weise zuzuordnende Module im Relais platzsparend, geschützt und isoliert so unterzubringen, daß auch eine Montage ohne besonderen Aufwand erfolgen kann.This invention was based on the object, in a small relay according to the preamble of
Gemäß der Erfindung ist deshalb vorgesehen, daß die Kammer so angeordnet ist, daß die Anschlußstifte des Moduls oder der Module nach der Bestückung der Kammer auf der gleichen Seike der Bodenplatte stehend und in die gleiche Richtung wie die äußeren Anschlußenden des Kontaktfedersatzes und der Spulenanschlüsse weisend angeordnet sind, derart, daß sie auch nach dem Verschluß der Kammer kontaktierbar sind.According to the invention it is therefore provided that the chamber is arranged in such a way that the connection pins of the module or modules, after the assembly of the chamber, stand on the same side of the base plate and are arranged in the same direction as the outer connection ends of the contact spring set and the coil connections are such that they can be contacted even after the chamber has been closed.
In der weiteren Ausbildung der Erfindung ist dann vorgesehen, daß die Kammer mit einer boden- oder anschlußseitigen Öffnung für die Modulbestückung in die Bodenplatte eingeformt ist, die nach der Bestückung durch eine einrastbare Abschlußplatte, durch Vergießen oder dgl. hermetisch verschlossen wird.In the further embodiment of the invention it is then provided that the chamber with a bottom or connection-side opening for the module assembly in the base plate is molded, which is hermetically sealed after being fitted with a snap-in cover plate, by casting or the like.
In einer anderen Ausführungsform ist vorgesehen, daß die Kammer mit bodenseitigen Durchführungen für die Anschlußstifte der Module und mit einer seitlichen Einschuböffnung für die Modul-Bestückung in die Bodenplatte eingeformt ist, die nach der Bestückung durch eine das Relais bis auf die Anschlußseite umschließende Kappe oder Haube verschlossen wird.In another embodiment it is provided that the chamber is formed with bottom-side bushings for the connection pins of the modules and with a side insertion opening for the module assembly in the base plate, which after the assembly by a cap or hood enclosing the relay up to the connection side is closed.
Mit einer solchen bereits in dem Bodenplatten-Formteil vorgesehenen Kammer sind die Module isoliert und vor mechanischen Beschädigungen von außen sicher in einem nach Verschließen der Einschuböffnung allseitig geschlossenen Raum untergebracht. Die Anschlußstifte der Module sind bei beiden bevorzugten Ausführungsformen gleichseitig und gleichgerichtet mit den anderen Anschlüssen des Relais herausgeführt, wodurch auch bei einer Platinenbestückung mit einem solchen Relais eine einfache Montage des Relais gegeben ist.With such a chamber already provided in the base plate molded part, the modules are insulated and safely protected from mechanical damage from the outside in a space closed on all sides after the insertion opening has been closed. The connection pins of the modules in both preferred embodiments are brought out in the same direction and in the same direction as the other connections of the relay, which means that the relay can be easily installed even when the circuit board is equipped with such a relay.
Die Module können sehr einfach innenseitig der Kammer festgelegt werden, so zum Beispiel mittels Rastnasen, die bereits im Formteil vorgesehen werden, oder, durch Vergiessen, wobei mit dem Vergießen gleichzeitig die Einschuböffnung der Kammer verschlossen werden kann. Andere Möglichkeiten des Abschlusses der Kammeröffnung sind durch eine separate, einrastbare Abschlußplatte, oder, bei seitlicher Einschuböffnung, durch die dem Relais zumeist zugeordnete überstreifbare Abdeckkappe gegeben.The modules can be very easily fixed on the inside of the chamber, for example by means of locking lugs which are already provided in the molded part, or by casting, the insertion opening of the chamber being closed at the same time as the casting. Other options for closing the chamber opening are provided by a separate, snap-in closing plate, or, in the case of a side insertion opening, by the cover cap which is usually associated with the relay.
Als Weiterbildung ist der Erfindung ist vorgesehen, daß die Innenseiten der Kammer für die Aufnahme eines in einer auf fünf Seiten geschlossenen Kassette untergebrachten Moduls ausgebildet ist, und am Rand der Einschuböffnung Rastnasen aufweist, an denen der das Volumen der Kammer vorzugsweise füllende Kassettenmodul einrastend in der Kammer festgelegt wird.As a further development of the invention it is provided that the inside of the chamber is accommodated for receiving a cassette closed on five sides Module is formed, and has latching lugs on the edge of the insertion opening, on which the cassette module, which preferably fills the volume of the chamber, is latched in the chamber.
Mit einem bereits in einem kassettenartigen Gehäuse gekapselt untergebrachten Modul wird die Montage des Relais selbst,unter Wegfall des Vergießens und/oder Verschließens der Kammeröffnung,weiter merklich vereinfacht.With a module that is already encapsulated in a cassette-like housing, the assembly of the relay itself is further simplified, with the omission of potting and / or closing the chamber opening.
Wesentlich ist, daß gegenüber den bisherigen Montageverfahren mit der Anordnung der Module in einer allseitig geschlossenen Kammer in einem Formteil des Relais, der Herstellungs- und Montageaufwand bedeutsam verringert werden kann.It is essential that, compared to the previous assembly methods, with the arrangement of the modules in a chamber closed on all sides in a molded part of the relay, the manufacturing and assembly effort can be significantly reduced.
Die Erfindung wird nun nachfolgend anhand von zwei in den Zeichnungsfiguren dargestellten bevorzugten Ausführungsbeispielen näher beschrieben.
In den Zeichnungen zeigt -
Figur 1- eine an sich bekannte Relais-Ausführungsform mit einer erfindungsgemäßen Kammer in der Bodenplatte, und -
Figur 2- ein speziell für erhöhte Sicherheitsanforderungen entwickeltes Relais mit einem in einem allseitig geschlossenen kassettenartigen Gehäuse angeordneten Magnetsystem, wobei im unteren Bereich oder in der Bodenplatte dieser Kassette die Kammer eingeformt ist.

- a known relay embodiment with a chamber according to the invention in the base plate, and -
- Figure 2
- a relay specially developed for increased security requirements with a magnet system arranged in a cassette-like housing that is closed on all sides, the chamber being formed in the lower area or in the base plate of this cassette.
In der Figur 1 ist eine an sich bekannte Ausführungsform eines Relais vereinfacht dargestellt. Ein Magnetsystem 1 trägt an einer Stirnseite verschwenkbar den Anker 2, der mit seinem freien Ende die Schaltkontaktfeder des Federkontaktsatzes 3 beaufschlagt, dessen Federkontakte wiederum in einem Federbock 4 festgelegt sind. In der Bodenplatte ist eine Kammer 8 derart eingeformt, daß die Anschlüsse des in diese Kammer einzusetzenden elektronischen Bausteins oder Moduls 9 gleichseitig und gleichgerichtet mit den Anschlußfahnen 7 des Federkontaktsatzes 3 und den Spulenanschlüssen 6 des Magnetsystems 1 aus der Bodenplatte heraustreten und kontaktierbar sind
In der Figur 2 ist eine für hohe Sicherheitsanforderungen bezüglich Kriech- und Luftstrecken ausgelegte Ausführungsform eines Relais dargestellt, dessen Magnetsystem 1 mit Spulenanschlußträger und Anker 2 in eine allseitig geschlossene Kassette eingeschoben wird, wobei der Anker 2 über einen Betätigungssteg die Umschaltkontaktfeder des Federkontaktsatzes 3 betätigt. Der Federbock 4 ist bei dieser Ausführungsform mit dem kassettenartigen Gehäuse für das Magnetsystem 1 als einstückiges Formteil ausgeführt, wobei im unteren Bereich dieses auch als Bodenplatte 5 zu bezeichnenden Formteils die Kammer 8 ähnlich der der Figur 1 angeordnet und eingeformt ist.A known embodiment of a relay is shown in simplified form in FIG. A
FIG. 2 shows an embodiment of a relay designed for high safety requirements with regard to creepage distances and clearances, the
Die Anschlüsse oder Anschlußstifte 10 des in dieser Kammer 8 angordneten Moduls 9 sind hier ebenfalls gleichseitig und gleichgerichtet mit den Anschlußfahnen 7 des Federkontaktsatzes 3 und den Spulenanschlüssen 6 des Magnetsystems herausgeführt und auf gleicher Ebene kontaktierbar.The connections or connecting
Aus beiden Figuren geht hervor, daß, bezogen auf die Darstellung in den Figuren, der Modul 9 an oder zwischen innenseitig der Kammer 8 eingeformten Rastnasen 11 festgelegt ist. Es ist auch daraus ersichtlich, daß die Einschuböffnung für den Modul 9 bodenseitig oder seitlich angeordnet oder vorgesehen werden kann. Bei einer bodenseitigen Öffnung für den Einschub des Moduls 9 kann die Öffnung durch eine Abschlußplatte einrastbar oder einklebbar verschlossen werden. Eine andere Möglichkeit besteht darin, daß die Kammer 8 mit einer an sich bekannten Masse ausgegossen wird.It can be seen from both figures that, based on the representation in the figures, the
Aus beiden dargestellten Ausführungsformen kann auch entnommen werden, daß die Kammer 8 auch mit einer seitlichen Öffnung ausgebildet werden kann, wobei die Anschlüsse oder Anschlußstifte 10 des eingesetzten Moduls 9 durch entsprechende bodenseitige Durchführungen gleichgerichtet mit den Anschlüssen 7 und/oder 6 des Federkontaktsystems 3 bzw. des Magnetsystems 1 herausgeführt sind. Mit einer seitlichen Einschuböffnung bietet sich zudem noch an, daß eine zwar nicht dargestellte Haube des Relais, die bis zur Unterkante des Federbocks 4 der Figur 1 bzw. des kassettenartigen Gehäuses 5 der Figur 2 übergeschoben wird, diese seitliche Öffnung der Kammer 8 verschließt.It can also be seen from both of the illustrated embodiments that the
Eine Weitere vorteilhafte Ausbildung gemäß der Erfindung kann dadurch erreicht werden, indem in diese Kammer 8 ein in einem Miniaturgehäuse in Kassettenform angeordneter oder eingebetteter Modul 9 als in sich geschlossene Einheit eingebracht und in dieser Kammer 8 durch entsprechend angeordnete Rastnasen 11 festgelegt wird.A further advantageous embodiment according to the invention can be achieved by introducing into this chamber 8 a
Die erfindungsgemäßen Merkmale sind auch für Relais mit einem gegenüber den dargestellten und beschriebenen Ausführungsformen konstruktiv anderen Aufbau anwendbar.The features according to the invention can also be used for relays with a construction that is different in construction from the embodiments shown and described.
