Description
Relais mit Koppelelement Relay with coupling element
Die Erfindung betrifft ein Relais mit Koppelelement, nach dem Oberbegriff des Patentanspruchs 1. Bei derartigen Relais besteht das Bedürfnis, die Relaisfunktionen zu verdoppeln oder zu verdreifachen, um aus einem „Relais- Einling" einen „Zwilling" oder „Drilling" zu machen. Ein derartiges Bedürfnis besteht vorallem in der Sicherheitstechnik, wo es darauf ankommt, daß im Fehlerfall, zum Beispiel beim Verschmelzen oder Blockieren von Kontakten immer noch parallele Kontakte vorhanden sind, welche die Schaltfunktion übernehmen.The invention relates to a relay with a coupling element, according to the preamble of claim 1. In such relays there is a need to double or triple the relay functions in order to make a "single" from a "twin" or "triplet" Such a need exists above all in safety technology, where it is important that in the event of a fault, for example when contacts are merging or blocking, there are still parallel contacts which take over the switching function.
Ein anderes Bedürfnis liegt darin, mit möglichst wenig Verschaltungsaufwand auf möglichst geringem Raum eine Vielzahl von Relaiskontakten unterzubringen. Auch hier ist es erforderlich, bestimmte elektrische Funktionen des Relais- Einlings auf den daraus hergestellten Zwilling zu übertragen, um eine unerwünschte Redundanz zu vermeiden. Beispielsweise ist es in diesem Fall erwünscht, daß bei einem Relais-Zwilling alle passive Kontaktfedern sowohl des einen als auch des anderen Federbox auf dem gleichen elektrischen Potential liegen. Man will aber keine Verschaltungen auf einer Schaltplatine anbringen, welches diese Anforderung erfüllt, sondern die Kontaktfedern sollten unmittelbar elektrisch miteinander verbunden sein.Another need is to accommodate a large number of relay contacts with as little wiring as possible in the smallest possible space. Here, too, it is necessary to transfer certain electrical functions of the single relay to the twin produced therefrom in order to avoid undesired redundancy. For example, in this case it is desirable that in a relay twin all passive contact springs of both the one and the other spring box are at the same electrical potential. However, one does not want to install any interconnections on a circuit board that meets this requirement, but the contact springs should be directly electrically connected to one another.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Relais der Eingangs genannten Art so weiter zu bilden, daß ohne Schaltungsaufwand zu einem Relais- Zwilling oder einem Relais-Drilling ausgebildet werden kann.The invention is therefore based on the object of developing a relay of the type mentioned in such a way that it can be formed into a relay twin or a relay triplet without circuitry.
Zur Lösung der gestellten Aufgabe ist das Relais durch die technische Lehre des Anspruches 1 gekennzeichnet.To solve the problem, the relay is characterized by the technical teaching of claim 1.
Wesentliches Merkmal ist, daß nach der Erfindung ein Koppelelement vorgesehen ist, welches mehrere Federböcke mechanisch miteinander koppelt. Auf diese Weise kann ein Einfach-Relais schnell über die Verbindung mittel eines Koppelelementes zu einem Mehrfach-Relais, z. B. einem Relais-Zwilling oder einem Relais-Drilling ausgebildet werden.An essential feature is that, according to the invention, a coupling element is provided which mechanically couples several spring brackets to one another. In this way, a single relay can quickly via the connection medium of a coupling element to a multiple relay, for. B. a relay twin or a relay triplet.
Die schnelle, mechanische Verbindung mittels eines Koppelelementes wird also als wesentliches Merkmal der vorliegenden Erfindung beansprucht.
In einer Weiterbildung der Erfindung ist es vorgesehen, daß das Koppelelement gleichzeitig auch die elektrische Durchverbindung zwischen den Federböcken in sich trägt, so daß also ein außenliegender Verschaltungsaufwand (z. B. über eine Verschaltungsplatine auf der die Relais mit ihren Anschlußstiften aufsitzen) vermieden wird, und daß mit Hilfe der mechanischen Kopplung desThe fast, mechanical connection by means of a coupling element is therefore claimed as an essential feature of the present invention. In a further development of the invention it is provided that the coupling element also carries the electrical through connection between the spring brackets in itself, so that an external connection effort (e.g. via a circuit board on which the relays are seated with their connecting pins) is avoided. and that with the help of the mechanical coupling of the
Koppelelementes auch gleichzeitig die elektrische Kopplung der zu verbindenden Federböcke hergestellt wird. In einer bevorzugten Weiterbildung der Erfindung ist es hierbei vorgesehen, daß die elektrische Verbindung der miteinander verbindenden Federböcke über die passiven Kontaktfedern erfolgt. Zu diesem Zweck ist es vorgesehen, daß nicht mehr einzelne, passive Kontaktfedern dem jeweiligen Federbock zugeordnet werden, sondern daß eine der beiden Federböcke zugeordnete Doppel-Kontaktfeder vorgesehen ist, welche aus zwei einzelnen Kontaktfedern besteht, die mittels eines elektrisch leitenden Verbindungssteges miteinander verbunden sind. Damit besteht der Vorteil, daß eine derartige Doppelkontaktfeder zunächst mit dem Koppelelement verbunden wird und daß dann das Koppelelement so mit den zu verbindenden Federböcken verbunden wird, so daß die eine Feder der Doppelkontaktfeder beispielsweise die passive Kontakfeder des einen Federbockes bildet, während die andere Feder der Doppelkontaktfeder, die andere passive Kontaktfeder des anderen Federbockes bildet. Beide Kontaktfedern sind hierbei dann aufgrund ihrer elektrischen Verbindung über den Verbindungssteg, welcher das Kontaktelement durchsetzt auf elektrisch gleichem Potential.Coupling element at the same time the electrical coupling of the spring bracket to be connected is produced. In a preferred development of the invention, it is provided that the electrical connection of the interconnecting spring brackets takes place via the passive contact springs. For this purpose, it is provided that individual passive contact springs are no longer assigned to the respective spring block, but that one of the two spring blocks is assigned a double contact spring which consists of two individual contact springs which are connected to one another by means of an electrically conductive connecting web. This has the advantage that such a double contact spring is first connected to the coupling element and that the coupling element is then connected to the spring brackets to be connected, so that one spring of the double contact spring forms, for example, the passive contact spring of a spring bracket, while the other spring Double contact spring, which forms the other passive contact spring of the other spring bracket. Both contact springs are then due to their electrical connection via the connecting web, which penetrates the contact element to the same electrical potential.
Die hier angegebene Definition von aktiven und passiven Kontaktfedern darf nicht schutzrechteinschränkend verstanden werden. Vielmehr liegt es im Rahmen der Erfindung, statt der hier beschriebenen passiven Kontaktfedern auch die aktiven Kontaktfedern mittels eines Kontaktelementes elektrisch leitend über ein Koppelelement dadurch zu verbinden, daß auf jeweils einer Seite des Koppelelementes die jeweilige, zugeordnete Kontaktfeder angeordnet ist und die elektrisch leitfähige Verbindung zwischen diesen Kontaktfedern durch einen Vebindungssteg bewerkstelligt wird, der das Koppelelement durchsetzt und mit diesem befestigt ist.The definition of active and passive contact springs given here must not be interpreted as restricting intellectual property rights. Rather, it is within the scope of the invention, instead of the passive contact springs described here, to connect the active contact springs in an electrically conductive manner by means of a contact element via a coupling element in that the respective associated contact spring is arranged on one side of the coupling element and the electrically conductive connection between this contact springs is brought about by a connecting web which passes through the coupling element and is fastened to it.
In einer bevorzugten Ausgestaltung der Erfindung ist es vorgesehen, daß die Koppelung des Kopplungselementes rastend und wieder lösbar mit den zu verbindenden Federböcken ausgebildet ist.In a preferred embodiment of the invention it is provided that the coupling of the coupling element is designed to be latching and releasable again with the spring brackets to be connected.
In einer anderen Ausgestaltung der Erfindung ist es vorgesehen, daß die Kopplung des Koppelelementes mit den Federböcken fest ausgebildet ist. Es
kann hier beispielsweise eine klebe-, schweiß- oder andere stofflüssige Verbindung verwendet werden.In another embodiment of the invention it is provided that the coupling of the coupling element with the spring brackets is fixed. It can be used here, for example, an adhesive, sweat or other fluid connection.
Ein besonders gedrängter Aufbau ergibt sich dann, wenn die aktiven und passiven Kontaktfedern im Winkel von 90° angeordnet sind.A particularly compact design results when the active and passive contact springs are arranged at an angle of 90 °.
Zur elektrischen Potentialtrennung zwischen den beiden Federböcken wird im übrigen bevorzugt, wenn das Koppelelement aus einem isolierenden Werkstoff besteht und mindestens eine parallel zu den Kontaktreihen des Relais verlaufende Trennwand aufweist, an der seitliche Ansätze angeformt sind, welche in zugeordneten Aufnahmeöffnungen am jeweiligen Federbock eingreifen.For the electrical potential separation between the two spring brackets, it is preferred, moreover, if the coupling element consists of an insulating material and has at least one partition wall running parallel to the contact rows of the relay, on which lateral projections are formed, which engage in assigned receiving openings on the respective spring bracket.
Zwischen den seitlichen Ansätzen der Trennwand sind Nuten ausgebildet, welche zur Aufnahme der Kontaktfedern geeignet sind. Nachdem andererseits parallel zu den Längsachsen der Aufnahmeöffnungen im jeweiligen Federbock zur Stirnseite hin geöffnete Schlitze angeordnet sind, können dort die passiven Kontaktfedern eingeschoben werden.Grooves which are suitable for receiving the contact springs are formed between the lateral approaches of the partition. After, on the other hand, slots are opened parallel to the longitudinal axes of the receiving openings in the respective spring bracket towards the end face, the passive contact springs can be inserted there.
Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Das Einzel-Relais besteht aus einem Federbock 1 , an dem der Antrieb 5 angeordnet ist. Auf dem Federbock 1 ist eine aktive Kontaktfeder 2 liegend angeordnet, die von einem Betätiger 4 betätigt wird. Stehend im Federbock ist eine passive Kontaktfeder 3 jeweils angeordnet. Alle Kontaktsätze sind in einer Kontaktreihe 25 angeordnet, wobei die Kontaktsätze voneinander durch zugeordnete Trennwände 12 voneinander getrennt sind.The single relay consists of a spring bracket 1 on which the drive 5 is arranged. An active contact spring 2, which is actuated by an actuator 4, is arranged lying on the spring bracket 1. A passive contact spring 3 is arranged standing in the spring bracket. All contact sets are arranged in a contact row 25, the contact sets being separated from one another by associated partition walls 12.
Die jeweilige passive Kontaktfeder liegt hierbei an einem gehäusefesten Anlagesteg 11 an. Das Antriebssystem wird über, nach unten herausgeführte Anschlußstifte 6 kontaktiert, ebenso wie die aktiven und passiven Kontaktfedern 2, 3 durch zugeordnete Anschlußstifte 7 nach unten herausgeführt sind.The respective passive contact spring bears against a housing web 11 fixed to the housing. The drive system is contacted via connection pins 6 which are led out downwards, just as the active and passive contact springs 2, 3 are led out downwards by assigned connection pins 7.
Wichtig ist nun, daß die eine Stirnseite des Federbocks 1 stirnseitig offene Aufnahmeöffnungen 8 aufweist, die zum Eingriff von zugeordneten Ansätzen 16 eines Koppelementes 14 bestimmt sind. Zwischen den Aufnahmeöffnungen 8 sind Schlitze 9 ausgebildet, in welche die passiven Kontaktfedern 3 von der Stirnseite her eingeschoben und dort gehaltert sind. Die Halterung erfolgt hierbei von mehrfach abgekröpften Nuten 10, so daß eine günstige, stabile Halterung der jeweilige Kontaktfeder 3 gewährleistet ist.It is now important that the one end face of the spring bracket 1 has receiving openings 8 which are open at the end and which are intended for the engagement of associated projections 16 of a coupling element 14. Slits 9 are formed between the receiving openings 8, into which the passive contact springs 3 are inserted from the end face and are held there. The mounting is carried out by multiple cranked grooves 10, so that a cheap, stable mounting of the respective contact spring 3 is guaranteed.
Mit Hilfe des Koppelelementes 14 soll nun aus dem Relais-Einling nach Figur 1 ein Relais-Zwilling nach den Figuren 2 bis 4 geschaffen werden. Hierzu ist das Koppelelement 14 vorgesehen, welches im wesentlichen aus einem Kunststoffteil besteht, welches eine mittige Trennwand 15 aufweist, deren Höhe etwa der Höhe des Federbocks 1 , 13 entspricht. Von der Trennwand 12 erstrecken sich jeweils in entgegengesetzten Richtungen die Ansätze 16, die zum Eingriff in die zugeordneten Aufnahmeöffnungen 8 der zu verbindenden Federböcke 1 ,13 bestimmt sind.With the aid of the coupling element 14, a relay twin according to FIGS. 2 to 4 is now to be created from the single relay according to FIG. 1. For this purpose, the coupling element 14 is provided, which essentially consists of a plastic part which has a central partition wall 15, the height of which corresponds approximately to the height of the spring bracket 1, 13. The lugs 16, which are intended to engage in the associated receiving openings 8 of the spring brackets 1, 13, extend from the partition wall 12 in opposite directions.
Die Trennwand 15 bildet im unteren Bereich eine etwa T-förmige Gestalt mit einem an der Trennwand 15 angeformten Querträger 20, an dessen Unterseite Stützrippen 17 angeordnet sind. Auf diese Weise wird eine günstige, biegesteife, mechanische Verbindung zwischen den zu verbindenden Federböcken 1 ,13 erreicht, denn gemäß der Darstellung in Figur 3 greift der Querträger 20 in eine zugeordnete, einseitig, offene Rastaufnahme 19 und ist dort mit zugeordneten Rastmitteln 18 festgelegt.
Zusätzlich kann eine stofflüssige Verbindung des Koppelelementes mit dem jeweiligen Federbock 1 ,13 dadurch erfolgen, daß die sich berührenden und ineinandergreifenden Teile mit Klebstoff verklebt sind.The partition wall 15 forms an approximately T-shaped shape in the lower region with a cross member 20 formed on the partition wall 15, on the underside of which support ribs 17 are arranged. In this way, a favorable, rigid mechanical connection between the spring brackets 1, 13 to be connected is achieved, because, as shown in FIG. 3, the cross member 20 engages in an associated, one-sided, open snap-in receptacle 19 and is fixed there with assigned snap-in means 18. In addition, a fluid connection of the coupling element to the respective spring bracket 1, 13 can be achieved in that the touching and interlocking parts are glued with adhesive.
Seitlich an der Trennwand 15 sind noch Abstandsrippen 24 angeordnet, welche abstandshaltend für die zugeordneten Stirnseiten der Aufnahmeöffnungen 8 sind. An diesen Abstandrippen 24 legen sich also die Stirnseiten der Aufnahmeöffnungen 8 der jeweiligen Federböcke 1 ,13 an.Spacer ribs 24 are also arranged laterally on the partition wall 15 and are spaced apart for the associated end faces of the receiving openings 8. The end faces of the receiving openings 8 of the respective spring brackets 1, 13 therefore rest on these spacer ribs 24.
Soll nun über die mechanische Verbindung derartiger Federböcke 1 ,13 auch eine elektrische Verbindung erfolgen, dann ist erfindungsgemäß eine Doppelkontaktfeder 21 vorgesehen, wie sie in Figur 4 dargestellt ist. Sie besteht aus den vorher genannten passiven Kontaktfedern 3, die mittels eines elektrisch leitfähigen Verbindungssteges 22 miteinander verbunden sind.If an electrical connection is now also to be made via the mechanical connection of such spring brackets 1, 13, then according to the invention a double contact spring 21 is provided, as shown in FIG. 4. It consists of the aforementioned passive contact springs 3, which are connected to one another by means of an electrically conductive connecting web 22.
Zur Montage wir daher die Doppelkontakfeder 21 in Pfeilrichtung 26 nach oben gegen die Unterseite des Koppelelementes 14 geschoben, so daß der Verbindungssteg in Eingriff mit den Nuten 23 zwischen den Ansätzen 16 kommt.For assembly we therefore pushed the double contact spring 21 upwards in the direction of arrow 26 against the underside of the coupling element 14, so that the connecting web comes into engagement with the grooves 23 between the lugs 16.
Es wird nun der rechte Federbock 1 in Pfeilrichtung 27 gegen das Koppelelement 14 geschoben, so daß die rechte Kontaktfeder 3 in den Schlitz 9 am Federbock 1 eingeschoben wird und gleichzeitig die Ansätze 16 in die Aufnahmeöffnungen 8 am Federbock eingreifen.The right spring bracket 1 is now pushed in the arrow direction 27 against the coupling element 14, so that the right contact spring 3 is inserted into the slot 9 on the spring bracket 1 and at the same time the lugs 16 engage in the receiving openings 8 on the spring bracket.
In analoger Weise erfolgt die Verbindung mit dem gegenüberliegenden Federbock 13.The connection to the opposite spring bracket 13 takes place in an analogous manner.
Hieraus ist erkennbar, daß nun neben der mechanischen Kopplung der Federböcke 1 ,13 auch eine elektrische Durchverbindung über die elektrisch miteinander verbundenen Kontaktfedern, 3,3 erfolgt ist. Es kann hierdurch wesentlicher Schaltungsaufwand eingespart werden, denn es ist nicht mehr notwendig, die Durchverbindung der Kontaktfedern anhand der Anschlußstifte 7 über eine nicht näher dargestellte Schaltplatine zu bewerkstelligen.
ZeichnungslegendeFrom this it can be seen that, in addition to the mechanical coupling of the spring brackets 1, 13, an electrical connection has now also been made via the electrically connected contact springs 3, 3. This can save considerable circuit complexity, because it is no longer necessary to connect the contact springs using the connecting pins 7 via a circuit board (not shown in more detail).
