Description

Die vorliegende Erfindung bezieht sich auf ein Relais, insbesondere Kleinstrelais, mit einem der Halterung der Magnetspule und des Kontaktfedersatzes dienenden Federbock.The present invention relates to a relay, in particular a small relay, with a spring bracket which serves to hold the magnetic coil and the contact spring set.

Relais werden heutzutage vielfach mit Flachsteckeranschlüssen versehen, aufgrund welcher Maßnahme es möglich ist, derartige Relais in sehr einfacher Weise in bereits vorhandene elektrische Schaltungen einzusetzen, bzw. im Fall einer Störung austauschen zu können.Nowadays, relays are often provided with flat plug connections, on the basis of which measure it is possible to use such relays in a very simple manner in existing electrical circuits, or to be able to replace them in the event of a fault.

Bei derartigen, mit Flachsteckeranschlüssen versehenen Relais erfolgt die Verbindung der einzelnen Flachstecker mit den Anschlüssen des Kontaktfedersatzes mit Hilfe innerhalb des Relais angeordneter Leiter, welche an den Anschlüssen der Flachstecker und des Kontaktfedersatzes beispielsweise durch Anlöten befestigt werden müssen.In such relays provided with flat plug connections, the individual flat plugs are connected to the connections of the contact spring set with the aid of conductors arranged inside the relay, which have to be fastened to the connections of the flat plug and the contact spring set, for example by soldering.

Im Hinblick auf diesen Stand der Technik ist es Aufgabe der vorliegenden Erfindung, ein Relais, insbesondere Kleinstrelais zu schaffen, welches im Hinblick auf die vorhandenen, getrennten räumlichen Verhältnisse einen stark vereinfachten Aufbau besitzt - in dem auf das Vorsehen getrennt innerhalb des Relais zu verlegender Verbindungsleiter verzichtet werden kann.In view of this prior art, it is an object of the present invention to provide a relay, in particular a small relay, which has a greatly simplified structure in view of the existing, separate spatial conditions - in the connecting conductor to be routed separately within the relay can be dispensed with.

Erfindungsgemäß wird dies dadurch erreicht, daß die einzelnen Kontaktfedern des Kontaktfedersatzes nach unten hin 5 mit einstückig angeformten Flachsteckern versehen sind, welche durch in der Bodenwandung des Federbockes angeordnete Schlitze hinduchgeführt und in diesem Bereich sowohl kraft- wie auch formschlüssig positionsmäßig fixiert sind.According to the invention, this is achieved in that the individual contact springs of the contact spring set 5 are provided at the bottom 5 with integrally molded tabs, which are guided through slots arranged in the bottom wall of the spring bracket and are fixed in position in this area both positively and positively.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich anhand der Unteransprüche.Advantageous developments of the invention result from the subclaims.

Die vorliegende Erfindung basiert auf der Erkenntnis, daß der vorgesehene Kontaktfedersatz des betreffenden Relais derart modifiziert werden kann, daß die im Normalfall im Innern des jeweiligen Relais vorgesehenen Leitungsanschlüsse des Kontaktfedersatzes auf der Außenseite des Relais zu liegen gelangen, in welchem Fall die betreffenden Leitungsanschlüsse unmittelbar in Form von Flachsteckeranschlüssen ausgebildet werden können, so daß auf das Vorsehen von innerhalb des Relais angeordneter, getrennt zu verlegender Verbindungsleiter verzichtet werden kann. Die Positionsfixierung des Kontaktfedersatzes mit den einstückig angeformten Flachsteckern erfolgt dabei zweckmäßigerweise innerhalb einer Adapterplatte, welcher unter Einsatz vonRippen und Nuten an der Bodenwandung des Federbockes des betreffenden Relais befestigbar ist. Die vorgesehene Adapterplatte muß dabei derart ausgebildet sein, daß mit Hilfe desselben sowohl die auf der Außenseite des Relais zu liegen gelangenden Flachstecker, wie auch die auf der Innenseite des Relais angeordneten Kontaktfedern positionsmäßig fixiert sind. Die positionsmäßige Fixierung dieser Elemente kann dabei entweder durch Umspritzen, Festkleben oder seitliches Aufschieben des mit den Flachsteckern versehenen Kontaktfedersatzes in innerhalb der Adapterplatte vorgesehene Schlitze erfolgen.The present invention is based on the knowledge that the intended contact spring set of the relay in question can be modified such that the line connections of the contact spring set provided in the interior of the respective relay normally come to lie on the outside of the relay, in which case the relevant line connections directly in Form of flat plug connections can be formed, so that the provision of arranged within the relay, separately to be laid connecting conductors can be dispensed with. The position of the contact spring set with the one-piece molded flat plugs is expediently carried out within an adapter plate, which can be fastened to the bottom wall of the spring bracket of the relay in question using ribs and grooves. The adapter plate provided must be designed in such a way that both the tabs to be located on the outside of the relay and the contact springs arranged on the inside of the relay are fixed in position with the aid of the same. The positional fixation of these elements can take place either by extrusion coating, gluing or laterally pushing on the contact spring set provided with the flat plugs into slots provided within the adapter plate.

Die innerhalb der Adapterplatte vorgesehenen Schlitze bzw. Führungsnuten sind dabei zweckmäßigerweise Z-förmig ausgelegt, wodurch einerseits eine gute positionsmäßige Arretierung der einzelnen Kontaktfedern mit ihren Flachsteckern zustande kommt, während andererseits unter Aufrechterhaltung eines relativ geringen, gegenseitigen Abstandes der einzelnen Kontaktfedern der gegenseitige Abstand zwischen den einzelnen Flachsteckern vergrößert wird, was im Hinblick auf die erforderlichen Isolationseigenschaften vielfach wünschenswert bzw. erforderlich erscheint. Zur weiteren Vergrößerung der vorhandenen Kriechsteckern besteht fernerhin die Möglichkeit, daß auf der Außenseite der Adapterplatte zusätzliche Rippen oder Nuten vorgesehen sind, welche zwischen den einzelnen Flachsteckern verlaufen. Die vorgesehene Adapterplatte ist schließlich noch derart ausgebildet, daß unter Einsatz der vorgesehenen Adapterplatte die Befestigung des Relais innerhalb einer elektrischen Schaltung möglich ist.The slots or guide grooves provided within the adapter plate are expediently designed in a Z-shape, which on the one hand ensures a good position Locking of the individual contact springs with their tabs comes about, while on the other hand the mutual distance between the individual tabs is increased while maintaining a relatively small mutual distance between the individual tabs, which often appears desirable or necessary in view of the required insulation properties. To further enlarge the existing crawling plugs, there is also the possibility that additional ribs or grooves are provided on the outside of the adapter plate, which run between the individual flat plugs. The provided adapter plate is finally designed such that the relay can be attached within an electrical circuit using the provided adapter plate.

Die Erfindung soll nunmehr anhand von Ausführungsbeispielen näher beschrieben und erläutert werden, wobei auf die beigefügte Zeichnung Bezug genommen ist.The invention will now be described and explained in more detail with reference to exemplary embodiments, reference being made to the accompanying drawing.

Das in den Figuren 1 - 3 gezeigte Kleinstrelais 1 enthält ein Antriebssystem, dessen Spule über Spulenanschlüsse 29, 30 ansteuerbar ist. Der Anker wirkt dabei auf einen Kontaktfedersatz, welcher aus drei Kontaktfedern 14 bis 16 besteht. Diese Kontaktfedern 14 bis 16 sind dabei einstückig mit aus der Bodenfläche des Relais ragenden Flachsteckern 2, 22 ausgebildet. Die Kontaktfedern 14 bis 16 führen dabei durch Schlitze 23 eines Federbocks 21 hindurch und sind von geraden bzw. Z-förmig ausgebildeten Schlitzen 7, 27 einer Adapterplatte 3 positionsmäßig fixiert. Die Adapterplatte 3 dient dabei dazu, daß die auf die Flachstecker 2, 22 einwirkenden Steckkräfte nicht auf den Federbock 3 und damit auf die Kontaktfedern 14 bis 16 übertragen werden können. Dies wird dadurch erreicht, daß beispielsweise an dem mittleren Flachstecker 22 ein vorstehender Lappen 4 vorgesehen ist, welcher in eine entsprechende Rastöffnung 5 im Bereich der Führungsnut 27 zum Einrasten gelangt. Die Positionierung der beiden äußeren Kontaktfedern 14, 16 erfolgt hingegen dadurch, daß die entsprechende Federungsnut 7 der Adapterplatte 3 sowie die darin zu liegen gelangenden Flachstecker 2 Z-förmig ausgebildet sind, so daß auf diese Weise eine gute Halterung zustande kommt.The small relay 1 shown in FIGS. 1-3 contains a drive system, the coil of which can be controlled via coil connections 29, 30. The armature acts on a contact spring set, which consists of three contact springs 14 to 16. These contact springs 14 to 16 are integrally formed with tabs 2, 22 protruding from the bottom surface of the relay. The contact springs 14 to 16 thereby lead through slots 23 of a spring bracket 21 therethrough, and are straight or Z-shaped slots 7, 27 a p Ada terplatte 3 is fixed in position. The adapter plate 3 serves to ensure that the plug-in forces acting on the flat connectors 2, 22 cannot be transmitted to the spring bracket 3 and thus to the contact springs 14 to 16. This is achieved in that, for example, a protruding tab 4 is provided on the central tab 22, which engages in a corresponding latching opening 5 in the region of the guide groove 27. The positioning of the two outer contact springs 14, 16, on the other hand, takes place in that the corresponding spring groove 7 of the adapter plate 3 and the flat plugs 2 to be located therein are formed in a Z-shape, so that a good mounting is achieved in this way.

Die Adapterplatte 3 ist in senkrechter Ebene zur Zeichenebene der Figur 1 auf dem Federbock 21 des Kleinstrelais 1 aufschiebbar. Zur formschlüssigen Verbindung der Adapterplatte 3 mit der Bodenfläche des Federbocks 21 ist vorgesehen, daß an der der Bodenfläche zugewandten Seite der Adapterplatte 3 abragende Rippen vorhanden sind, die in entsprechende Nuten 3 an der Bodenfläche des Federbocks 21 zum Eingreifen gelangen. An den beiden Enden der Adapterplatte 3 sind zusätzlich Ansätze 10 mit Bohrungen 6 vorgesehen, durch welche nicht gezeigte Befestigungs- mittel hindurchführen, mit denen die Adapterplatte 3 auf einer beliebigen Befestigungsfläche befestigt werden kann.The adapter plate 3 can be pushed onto the spring bracket 21 of the small relay 1 in the plane perpendicular to the drawing plane of FIG. For the positive connection of the adapter plate 3 with the bottom surface of the spring bracket 21, it is provided that on the bottom surface facing side of the adapter plate 3 projecting ribs are present, which engage in corresponding grooves 3 on the bottom surface of the spring bracket 21. At the two ends of the adapter plate 3 projections 10 are provided with holes 6 provided in addition, by means of which not shown Fixed To g ungs- passage means with which the adapter plate can be mounted on any mounting face. 3

Die Figuren 4 bis 6 zeigen weitere Einzelheiten der Adapterplatte 3. Anhand dieser Figuren ist erkennbar, daß die als Führungsnuten 7 wirkenden Schlitze Z-förmig ausgebildet sind, während die Führungsnut 27 gerade ausgelegt ist. Im Bereich der Federungsnut 7, 27 ist jeweils eine Rastöffnung 5 vorgesehen, in welcher der jeweilige Flachstecker 2, 22 mit davon abragenden Lappen 4 zum Einrasten gelangt.Figures 4 to 6 show further details of the adapter plate 3. From these figures it can be seen that the slots acting as guide grooves 7 are Z-shaped, while the guide groove 27 is straight. In the area of the spring groove 7, 27, a latching opening 5 is provided, in which the respective tab connector 2, 22 with the tabs 4 projecting therefrom comes into engagement.

Figur 7 zeigt in schematischer, vergrößerter Darstellung die Art der Befestigung der Adapterplatte 3 auf den mit Flachsteckern 2, 22 versehen Kontaktfedern 14 bis 16. Anhand dieser Figur sind die an der Rückseite der Adapterplatte 3 vorstehenden Rippen 8 erkennbar, welche in entsprechenden Nuten 9 im Bereich des Federbocks 11 des Relais 1 zum Eingreifen gelangen. Hieraus wird deutlich, daß die Kontaktfedern 14 bis 16 jederzeit wieder aus den Schlitzen 23 des Federbocks 11 herausziehbar und gegen Kontaktfedern anderer Art ersetzbar sind.FIG. 7 shows a schematic, enlarged representation of the type of attachment of the adapter plate 3 to the contact springs 14 to 16 provided with tabs 2, 22. On the basis of this figure, the ribs 8 protruding on the rear side of the adapter plate 3 can be seen, which in corresponding grooves 9 in the Area of the spring bracket 11 of the relay 1 reach for intervention. It is clear from this that the contact springs 14 to 16 can be pulled out of the slots 23 of the spring bracket 11 at any time and can be replaced by contact springs of a different type.

Bei der in Figur 8 gezeigten Ausführungsform weist die Adapterplatte 13 auf der einen Seite Nuten 13 auf, deren Längserstreckung parallel zur Breitseite der Flachstecker 2, 22 verläuft, so daß zwischen den Flachsteckern Kriechsteckern vergrößerter Länge ausgebildet sind. Gegenüberliegend zu den Nuten 18 sind im Material der Adapterplatte 13 Rippen 17 ausgeformt, welche in die nicht näher dargestellten Nuten im Federbock des Relais 1 eingreifen. Bei dieser Ausführungsform sind ferner die Kontaktfedern 14 - 16 mit ihren Flachsteckern 2, 22 in das Material der Adapterplatte 13 eingespritzt, d.h. also unlösbar mit der Adapterplatte 13 verbunden. Anstelle des Einbettens im KunststoffmateriaL der Adapterplatte 13 kann die Befestigung der Kontaktfedern 14 bis 16 mit ihre Flachsteckern 2, 22 ebenfalls curch Einkleben erfolgen.In the embodiment shown in FIG. 8, the adapter plate 13 has grooves 13 on one side, the longitudinal extent of which extends parallel to the broad side of the flat plugs 2, 22, so that crawl plugs of increased length are formed between the flat plugs. Opposite to the grooves 18 13 ribs 17 are formed in the material of the adapter plate, which engage in the not shown grooves in the spring bracket of the relay 1. In this embodiment, the contact springs 14-16 are also injected with their tabs 2, 22 into the material of the adapter plate 13, i.e. thus permanently connected to the adapter plate 13. Instead of embedding in the plastic material of the adapter plate 13, the contact springs 14 to 16 can also be fastened with their flat plugs 2, 22 by gluing.

Bei der Ausführungsform nach Figur 9 ist eine Adapterplatte 19 vorgesehen, bei welcher die mittlere Führungsnut 27 dadurch axial verlängert ausgebildet ist, daß sie im Bereich einer keilförmig ausgebildeten Abstützung 20 der Adapterplatte 19 mündet. Es ist fernerhin erkennbar, daß die äußeren Kontaktfedern 14 und 16 mit Lappen 12 versehen sind, welche im Material des Federbocks 21 zum Einrasten gelangen. Hierdurch wird eine zusätzliche Lagensicherung der Kontaktfedern 14 - 16 im Bereich der Schlitze 23 gewährleistet.In the embodiment according to FIG. 9, an adapter plate 19 is provided, in which the central guide groove 27 is axially elongated by opening in the area of a wedge-shaped support 20 of the adapter plate 19. It can also be seen that the outer contact springs 14 and 16 are provided with tabs 12 which engage in the material of the spring bracket 21. This ensures additional securing of the position of the contact springs 14-16 in the area of the slots 23.

Figur 10 zeigt in perspektivischer, schematischer Ansicht eine weitere Ausführungsform einer Adapterplatte 31, welche in diesem Fall aus zwei Plattenteilen 32, 33 besteht, die unter Einsatz entsprechender Rastelemente 34, 35 zusammenschnappend miteinander verbindbar sind.FIG. 10 shows a perspective, schematic view of a further embodiment of an adapter plate 31, which in this case consists of two plate parts 32, 33, which can be snapped together using corresponding locking elements 34, 35.

Mit Hilfe dieser aus den beiden Plattenteilen 32, 33 bestehenden Adapterplatten 31 können die einzelnen Flachstecker mit den daran angeformten Kontaktfedern beispielsweise der Flachstecker 22 fest innerhalb der Adapterplatte 31 gehalten werden, wobei eine Umschließung des betreffenden Flachsteckers 22 von allen vier Seiten her erfolgt, so daß auf diese Weise die vorgesehenen Flachstecker positionsmäßig äußerst gut fixiert sind.With the help of these consisting of the two plate parts 32, 33 adapter plates 31, the individual flat plug with the molded contact springs, for example, the flat connector 22 are held firmly within the adapter plate 31, with the respective flat connector 22 being enclosed from all four sides, so that the intended flat connectors are extremely well fixed in position.

Figuren 11 und 12 zeigen eine weitere Ausführungsform einer im Rahmen der vorliegenden Erfindung zu verwendenden Adapterplatte 41, welche in diesem Fall derart ausgebildet ist, daß diese von unten her auf das mit Flachsteckeranschlüssen 2, 22 versehene Kleinstrelais 1 aufgesteckt werden kann. Die einzelnen Flachsteckeranschlüsse 2, 22 werden dabei von der Adapterplatte 41 vollständig umfaßt, so daß eine ausgezeichnete Isolierung der einzelnen Flachstecker 2, 22 zustande kormt. Bei der betreffenden Adapterplatte 41 sind in Übereinstimmung mit der Ausführungsform in Figur 1 ebenfalls Z-förmige Führungsnuten bzw. Führungsschlitze vorgesehen, in welchen die beiden äußeren Flachstecker 2 zu liegen gelangen. In Figur 12 sind dabei die Eintrittsstellen dieser Führungsnuten mit 45 bezeichnet.FIGS. 11 and 12 show a further embodiment of an adapter plate 41 to be used in the context of the present invention, which in this case is designed such that it can be plugged onto the small relay 1 provided with flat plug connections 2, 22 from below. The individual tab connectors 2, 22 are completely surrounded by the adapter plate 41, so that excellent insulation of the individual tabs 2, 22 is achieved.
