Description

Die Erfindung betrifft eine Relais-Baugruppe mit einem Sokkel, der einen flachen Bodenteil mit an der Oberseite angeformten Rippen und mit zur Unterseite durchgehenden Führungskanälen aufweist, mit einem eine Wicklung, einen Kern, ein Joch und einen Anker tragenden, zwei Flansche aufweisenden Spulenkörper, der mit an den Flanschen nach unten angeformten Fortsätzen auf dem Bodenteil ruht, wobei zumindest einer der Flansche eine Aufnahme für mindestens ein feststehendes Gegenkontaktelement aufweist, sowie mit in den Führungskanälen des Sockels zur Unterseite des Bodenteils durchgeführten Steckerelementen für das Gegenkontaktelement, für Wicklungsanschlüsse und für mindestens ein mit dem Anker gekoppeltes bewegliches Kontaktelement.The invention relates to a relay assembly with a socket, which has a flat bottom part with ribs formed on the top and with guide channels running through to the bottom, with a bobbin having a winding, a core, a yoke and an armature and having two flanges with projections formed on the flanges resting on the bottom part, at least one of the flanges having a receptacle for at least one fixed mating contact element, and with plug elements for the mating contact element, for winding connections and for at least one, carried out in the guide channels of the base to the underside of the bottom part movable contact element coupled to the armature.

Ein Relais mit einem vergleichbaren Aufbau auf einem Sockel ist beispielsweise aus der DE-OS 34 28 595 bekannt. Dort handelt es sich um ein Relais, bei dem der Sockel in herkömmlicher Weise nur die Fläche unterhalb des Magnetsystems einnimmt und bei dem die Anschlußelemente für die Erregerwicklung und für die Kontaktelemente alle in dem einen Bereich unterhalb des Magnetsystems aus dem Sockel austreten. Das bekannte Relais mit den Flachsteckern im Stecksockel kann somit entweder in eine entsprechend angepaßte Steckfassung eingesteckt werden, welche ihrerseits dann eine Einzelverdrahtung der Anschlüsse besitzen muß, oder die einzelnen Flachstecker des Relais können über Kabelschuhe mit Einzelleitungen kontaktiert werden. Für den Anschluß an mehradrige Kabel mit einem mehrpoligen Steckverbinder sind solche Relais nicht ausgelegt.A relay with a comparable structure on a base is known for example from DE-OS 34 28 595. There it is a relay in which the base occupies only the area below the magnet system in a conventional manner and in which the connection elements for the excitation winding and for the contact elements all emerge from the base in one area below the magnet system. The known relay with the flat plugs in the plug-in base can thus either be inserted into a correspondingly adapted socket, which in turn must have individual wiring of the connections, or the individual flat plugs of the relay can be contacted with individual lines via cable lugs. Such relays are not designed for connection to multi-core cables with a multi-pin connector.

Bei der Anwendung von Relais der eingangs genannten Art in verschiedenen Gebieten, beispielsweise in der Kraftfahrzeugtechnik, ergibt sich jedoch häufig das Bedürfnis, ein Relais als Schaltbaugruppe mit einer entfernt davon angeordneten Steuerung einerseits und mit einem oder mehreren wiederum an anderer Stelle angeordneten Verbraucher(n), beispielsweise einem Pumpenmotor oder einer Lampengruppe, in leicht austauschbarer Weise zu verbinden. Dies war bisher nur dadurch möglich, daß die am Relaissockel in eng verschachtelter Anordnung austretenden Flachstecker einzeln mittels Kabelschuhen kontaktiert wurden. Wollte man also beispielsweise den Verbraucher, also etwa einen Motor, austauschen, so mußte man am Relaissockel zwischen den verschiedenen Anschlüssen die Motorklemmen heraussuchen und die betreffenden Kabelschuhe abziehen.When using relays of the type mentioned in various areas, for example in automotive engineering, However, there is often the need to connect a relay as a switching module with a control arranged remotely therefrom on the one hand and with one or more consumers (s), for example a pump motor or a lamp group, which are in turn arranged elsewhere. Until now, this was only possible by contacting the tabs emerging from the relay base in a closely nested arrangement individually using cable lugs. For example, if you wanted to replace the consumer, for example a motor, you had to look for the motor terminals on the relay base between the different connections and remove the relevant cable lugs.

Aufgabe der Erfindung ist es, eine Relaisbaugruppe der eingangs genannten Art mit Steckeranschlüssen so zu gestalten, daß die Steuerung einerseits und der Verbraucher andererseits jeweils für sich mittels üblicher mehrpoliger Steckverbinder anschließbar sind, wobei zwischen dem Relaissystem und den jeweiligen Steckerelementen möglichst wenig und möglichst einfache Verbindungselemente erforderlich sind.The object of the invention is to design a relay assembly of the type mentioned at the beginning with plug connections so that the control on the one hand and the consumer on the other hand can each be connected by means of conventional multipole plug connectors, with as little and as simple as possible connecting elements between the relay system and the respective plug elements required are.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Sockel zur Oberseite des Bodenteils eine mit ringsum verlaufenden Seitenwänden versehene Relaiskammer und zur Unterseite des Bodenteils zumindest zwei Steckerschächte zur Aufnahme von jeweils einem mehrpoligen Steckverbinder bildet, daß das Gegenkontaktelement mit seinem nach unten angeformten Steckerelement in einem ersten Steckerschacht geführt ist, daß zumindest eine am Boden der Relaiskammer angeordnete, mit dem beweglichen Kontaktelement verbundene erste Stromleitschiene mit einem nach unten angeformten Steckerelement in einen zweiten Steckerschacht geführt ist und daß mindestens eine zweite Stromleitschiene vorgesehen ist, welche mit je einem nach unten angeformten Steckerelement in jeden der beiden Steckerschächte geführt ist.According to the invention, this object is achieved in that the base forms a relay chamber provided with all-round side walls at the top of the base part and at least two connector shafts for receiving a multipole connector each at the bottom of the base part, that the mating contact element with its molded-on connector element in a first It is guided that at least one first conductor rail arranged on the bottom of the relay chamber and connected to the movable contact element is guided into a second connector shaft with a connector element molded downward, and that at least one second conductor rail is provided, each with a connector element molded downwards each of the two connector slots is guided.

Durch die erfindungsgemäße Gestaltung der Relaisbaugruppe wird es möglich, über den ersten Steckerschacht mittels eines mehrpoligen Steckverbinders die Steuerung der Erregerspannung und die Spannungsquelle für den Laststromkreis anzukoppeln, während über den zweiten Steckerschacht der Verbraucher getrennt über einen eigenen mehrpoligen Steckverbinder angekoppelt wird. Während bei herkömmlichen Anordnungen der Verbraucher extern in Reihe mit der Spannungsquelle zwischen die beiden Kontaktanschlüsse des Relais geschaltet werden muß, können hier über zwei Steckeranschlüsse im ersten Steckerschacht die beiden Pole der Spannungsquelle angekoppelt werden. Die Steckerschächte können entsprechend den verwendeten Kabelsteckern rund oder rechteckig sein oder auch eine beliebige andere Form besitzen. Lediglich einer der Pole wird jedoch unmittelbar und nach Möglichkeit sogar mit einem einstückigen Stecker- und Kontaktelement in das Relais hineingeführt, während der zweite Pol, beispielsweise der Massepol, von dem ersten Steckerschacht über eine Stromleitschiene zu einem Stecker im zweiten Steckerschacht geführt ist. Ein weiterer Stecker des zweiten Steckerschachtes ist dann wiederum über eine interne Stromleitschiene mit dem zweiten Gegenkontaktelement des Relais verbunden. Auf diese Weise kann also der Verbraucher über zwei Pole eines mehrpoligen Steckers in den Schaltstromkreis des Relais eingekoppelt werden.The inventive design of the relay module makes it possible to couple the control of the excitation voltage and the voltage source for the load circuit via the first connector slot by means of a multi-pin connector, while the consumer is coupled separately via the second connector slot via its own multi-pin connector. While in conventional arrangements of the consumers, the voltage source must be connected externally in series with the two contact connections of the relay, the two poles of the voltage source can be coupled here via two plug connections in the first plug shaft. The connector slots can be round or rectangular, depending on the cable connector used, or can have any other shape. However, only one of the poles is directly and, if possible, even inserted into the relay with a one-piece plug and contact element, while the second pole, for example the ground pole, is guided from the first plug shaft via a current conductor rail to a plug in the second plug shaft. Another connector of the second connector slot is then in turn connected to the second mating contact element of the relay via an internal conductor rail. In this way, the consumer can be coupled into the switching circuit of the relay via two poles of a multipole plug.

Die Steckanschlüsse für die Erregerwicklung sind zweckmäßigerweise zusammen mit den Anschlüssen der Spannungsquelle über den ersten Steckerschacht geführt. Es wäre allerdings auch denkbar, für die Stromzuführung einerseits und für die Wicklungsanschlüsse jeweils getrennte Steckerschächte vorzusehen, so daß die Ankopplung an eine Stromquelle einerseits und an die Steuerung andererseits ebenfalls jeweils getrennte Kabel verwendet werden könnten. Dies wäre insbesondere dann zweckmäßig, wenn mehrere Relaissysteme in der Relaiskammer angeordnet und über eine gemeinsame Steuerung gleichzeitig oder unabhängig voneinander erregt werden.The plug connections for the field winding are expediently guided together with the connections of the voltage source via the first plug shaft. However, it would also be conceivable to provide separate plug shafts for the power supply on the one hand and for the winding connections, respectively, so that the connection to a power source on the one hand and to the controller on the other hand could also be used in each case in separate cables. This would be particularly useful if several relay systems are arranged in the relay chamber and excited simultaneously or independently of one another via a common control.

In weiterer Ausgestaltung kann auch vorgesehen werden, daß in der Relaiskammer zusätzliche Brückenschienen mit Stekkerelementen in beiden Steckerschächten angeordnet werden. Auf diese Weise können beispielsweise Sensorsignale, die vom Verbraucher über das Verbraucherkabel zugeführt werden, ohne weitere Maßnahmen über die Relais-Baugruppe zum Steuerungskabel und damit zur Steuerung durchgeschleift werden, wobei sie mit dem eigentlichen Relais nicht verschaltet sind. Von allen Stromleitschienen, die für die Schaltfunktion nur ein Steckerelement in einem Steckerschacht aufweisen, kann aber beispielsweise zu Testzwecken ein weiterer Steckeranschluß in dem anderen Steckerschacht vorgesehen werden, vorzugsweise in dem ersten Steckerschacht, der mit der Steuerung verbunden wird.In a further embodiment, it can also be provided that additional bridge rails with plug elements are arranged in both plug shafts in the relay chamber. In this way, for example, sensor signals that are supplied by the consumer via the consumer cable can be looped through the relay module to the control cable and thus to the controller without further measures, and they are not connected to the actual relay. Of all conductor rails, which have only one plug element in one plug shaft for the switching function, however, a further plug connection can be provided in the other plug shaft, for example for test purposes, preferably in the first plug shaft, which is connected to the controller.

In einer vorteilhaften Ausgestaltung ist weiterhin vorgesehen, daß die erwähnten Stromleitschienen oder zusätzliche Lötstützpunkte in der Relaiskammer Kerben zur Aufnahme von Anschlußdrähten zusätzlicher Bauelemente, wie Dioden, aufweisen. Solche Dioden können beispielsweise in Serie oder parallel zur Wicklung oder auch parallel zum Verbraucherkreis geschaltet sein. Aber auch andere elektronische oder auch elektromechanische Bauelemente können zusätzlich, wie auch zusätzliche Relaissysteme, in der Relaiskammer untergebracht sein.In an advantageous embodiment it is further provided that the current conducting rails or additional soldering support points in the relay chamber have notches for receiving connecting wires of additional components, such as diodes. Such diodes can, for example, be connected in series or in parallel to the winding or also in parallel to the consumer circuit. However, other electronic or electromechanical components can also be accommodated in the relay chamber, as well as additional relay systems.

Einige besondere Ausgestaltungen der Baugruppe sind in den Unteransprüchen angegeben.Some special configurations of the assembly are specified in the subclaims.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigen

  • 2 shows an exploded view of the individual parts of a relay module according to FIG. 1,
  • 3 shows a view of the relay module from the bottom.

Die in den FIG 1 bis 3 dargestellte Relais-Baugruppe besitzt als Grundkörper einen Sockel 1 mit einem im wesentlichen flachen Bodenteil 2, an welchem nach unten hin zwei im Beispiel zylindrisch gestaltete Steckerschächte 3 und 4 angeformt sind. In diese Steckerschächte ragen von der Oberseite durch den Bodenteil geführte Flachstecker, die später noch im einzelnen beschrieben werden. Sie werden durch Einstecken von Kabel-Steckverbindern (Steckerkupplungen) mit einem jeweiligen Kabel und damit mit einer entfernten Baugruppe verbunden, beispielsweise mit einer Steuerung oder mit einem Verbraucher. Im vorliegenden Beispiel ist der Steckerschacht 3 für einen siebenpoligen, der Steckerschacht 4 für einen vierpoligen Steckverbinder ausgelegt.The relay module shown in FIGS. 1 to 3 has a base 1 as a base body with an essentially flat base part 2, on which two connector shafts 3 and 4, which are cylindrical in the example, are formed at the bottom. In these plug shafts protrude from the top through the bottom part led flat connectors, which will be described later in detail. They are connected by inserting cable connectors (plug couplings) with a respective cable and thus with a remote module, for example with a controller or with a consumer. In the present example, the connector slot 3 is designed for a seven-pin connector, the connector slot 4 for a four-pin connector.

Zur Oberseite hin ist der rechteckige Bodenteil 2 des Sokkels 1 mit ringsum angeformten Seitenwänden 5 versehen, die eine zunächst nach oben offene Relaiskammer 6 bilden. Diese Relaiskammer kann mit einer übergestülpten Kappe 7 verschlossen werden, welche mit nicht sichtbaren Rastnasen in Ausnehmungen 8 der Seitenwände 5 einrasten. Innerhalb der Relaiskammer 6 weist der Bodenteil 2 jeweils Rippen 9 auf, die zwischenliegende Führungsschächte und Nuten zur Halterung eines Magnetsystems sowie von Stromleitschienen oder auch von zusätzlichen Bauelementen dienen. Zwischen den Rippen sind außerdem im Boden 2 Durchführungen 10 vorgesehen, in denen Steckerelemente, vorzugsweise Flachstecker, nach unten in die Steckerschächte 3 und 4 durchgeführt sind.Towards the top, the rectangular bottom part 2 of the base 1 is provided with all-round molded side walls 5, which form a relay chamber 6 which is initially open at the top. This relay chamber can be closed with a cap 7, which snaps into recesses 8 of the side walls 5 with not visible locking lugs. Within the relay chamber 6, the bottom part 2 has ribs 9, which serve the intermediate guide shafts and grooves for holding a magnet system as well as conductor rails or additional components. Between the ribs 2 bushings 10 are also provided in the bottom, in which plug elements, preferably flat plugs, are carried down into the plug shafts 3 and 4.

In der Relaiskammer 6 ist ein Relaissystem angeordnet, welches als Träger einen Spulenkörper 11 mit zwei Flanschen 12 und 13 besitzt, zwischen denen eine Wicklung 14 aufgebracht ist. Mit nach unten angeformten Fortsätzen 15 und 16 der Flansche 12 und 13 ruht der Spulenkörper auf Rippen 9 des Sockelbodens 2, wobei beispielsweise Ausnehmungen 17 in den Spulenkörperfortsätzen mit entsprechenden Formen der Rippen ineinandergreifen können. Das Magnetsystem besitzt weiterhin einen Kern 18, ein winkelförmiges Joch 19 und einen flachen Anker 20, der wie das Joch mit seiner Hauptebene senkrecht zum Boden 2 steht. Das Magnetsystem ist somit in hergebrachter Weise aufgebaut, so daß eine nähere Beschreibung nicht erforderlich ist.In the relay chamber 6, a relay system is arranged, which has a coil body 11 with two flanges 12 and 13 as a carrier, between which a winding 14 is applied. With projections 15 and 16 of the flanges 12 and 13 formed downward, the coil body rests on ribs 9 of the Base 2, wherein, for example, recesses 17 in the bobbin extensions can interlock with corresponding shapes of the ribs. The magnet system also has a core 18, an angular yoke 19 and a flat armature 20 which, like the yoke, is perpendicular to the bottom 2 with its main plane. The magnet system is thus constructed in a traditional manner, so that a detailed description is not necessary.

Am Spulenkörperflansch 13 ist eine in der Zeichnung nicht sichtbare Kontakttasche zur Aufnahme eines feststehenden Gegenkontaktelementes 21 angeformt. Eine mögliche Ausgestaltung dieser Tasche ist beispielsweise in der DE-OS 34 28 595 gezeigt. Das feststehende Gegenkontaktelement 21 besitzt einen nach oben in die erwähnte Tasche reichenden Kontaktschenkel 21a, außerdem einen Befestigungsteil 21b, der zwischen Rippen des Sockels einerseits und dem Spulenkörper andererseits eingeklemmt ist und damit fixiert wird, sowie einen nach unten angeformten Flachstecker 21c, der durch eine entsprechende Durchführung im Boden 2 in den Steckerschacht 3 geführt ist.A contact pocket (not visible in the drawing) for receiving a stationary mating contact element 21 is formed on the coil former flange 13. A possible embodiment of this bag is shown for example in DE-OS 34 28 595. The fixed counter-contact element 21 has a contact leg 21a which extends upwards into the pocket mentioned above, also a fastening part 21b which is clamped between the ribs of the base on the one hand and the coil former on the other hand and is thus fixed, and a flat plug 21c which is formed on the bottom and which is connected by a corresponding Implementation in the floor 2 in the connector slot 3 is performed.

Als bewegliches Kontaktelement dient eine Kontaktfeder 22, die an der Außenseite des Ankers 20 auf diesem aufliegt und mit ihm verschweißt oder vernietet ist. Am freien Ende dieser Kontaktfeder 22 ist ein Kontaktschenkel 22a vorgesehen, der mit dem Kontaktschenkel 21a des Gegenkontaktelementes 21 zusammenwirkt. Ein weiterer Schenkel 22b der Kontaktfeder dient in bekannter Weise zur Ankerrückstellung. Als Stromzuführung zur Kontaktfeder 22 ist eine Litze 23 vorgesehen, welche einerseits mit dem Kontaktniet im Kontaktfederschenkel 22a und andererseits mit einer Stromleitschiene 24 verschweißt ist. Diese Stromleitschiene 24, die mit ihrem Mittelteil 24a zwischen Rippen 9 des Sockels befestigt ist, besitzt einen nach unten angeformten, in den Steckerschacht 4 reichenden Flachstecker 24b, außerdem am anderen Ende einen in den Steckerschacht 3 reichenden, zu Testzwekken dienenden Flachstecker 24c.A contact spring 22 serves as the movable contact element, which rests on the outside of the armature 20 and is welded or riveted to it. At the free end of this contact spring 22, a contact leg 22a is provided which interacts with the contact leg 21a of the mating contact element 21. Another leg 22b of the contact spring is used to reset the armature in a known manner. A wire 23 is provided as the power supply to the contact spring 22, which is welded on the one hand to the contact rivet in the contact spring leg 22a and on the other hand to a current guide rail 24. This conductor rail 24, which is fastened with its central part 24a between ribs 9 of the base, has a flat plug 24b which is formed downwards and extends into the plug shaft 4, and also at the other end has a flat plug 24c which extends into the plug shaft 3 and is used for test purposes.

Eine weitere Stromleitschiene 25, die in ähnlicher Weise zwischen Rippen 9 des Sockels verankert ist, besitzt ebenfalls einen Mittelteil 25a, der wie der Mittelteil 24a der ersten Stromleitschiene mit der Hauptebene senkrecht zur Bodenebene stehend zwischen Rippen 9 angeordnet ist und zwei nach unten angeformte Flachstecker 25b und 25c, die in den Steckerschacht 3 bzw. in den Steckerschacht 4 hineinreichen.Another conductor rail 25, which is anchored in a similar manner between ribs 9 of the base, also has a central part 25a which, like the central part 24a of the first conductor rail, is arranged with the main plane perpendicular to the floor plane between ribs 9 and two flat plugs 25b formed downward and 25c, which extend into the connector slot 3 and into the connector slot 4, respectively.

Zur Kontaktierung der Wicklungsanschlüsse sind im Sockel weitere Flachstecker 26 und 27 verankert, welche an der Oberseite jeweils Kerben 26a bzw. 27a zur Aufnahme und zum Klemmen und/oder Verlöten von Anschlußdrähten aufweisen. Falls gewünscht, können die in den Spulenflanschen 12 bzw. 13 verankerten Wicklungsstützdrähte 28 direkt über die Kerben 26a bzw. 27a mit den zugehörigen Flachsteckern verbunden werden. Soll jedoch beispielsweise eine Diode 29 in Serie zur Wicklung geschaltet werden, so kann ein Wicklungsende der Spule auf einen im Sockel verankerten Stützpunkt 30 geführt werden, während die Diode 29 dann zwischen den Kerben 30a und 27a eingelötet wird. Auch eine Paralleldiode 31 kann zwischen den Kerben 26a und 27a eingelötet sein. Außerdem können zusätzliche Bauteile in der Relaiskammer untergebracht und mit den verschiedenen Anschlüssen verbunden sein. Beispielsweise ist zwischen den beiden Stromleitschienen 24 und 25 eine Paralleldiode 32 vorgesehen, welche in entsprechenden Kerben 24d und 25d dieser Stromleitschienen geklemmt bzw. verlötet ist.To make contact with the winding connections, further tabs 26 and 27 are anchored in the base, each of which has notches 26a and 27a on the upper side for receiving and for clamping and / or soldering connecting wires. If desired, the winding support wires 28 anchored in the coil flanges 12 and 13 can be connected directly to the associated flat plugs via the notches 26a and 27a. However, if, for example, a diode 29 is to be connected in series to the winding, one winding end of the coil can be guided to a base 30 anchored in the base, while the diode 29 is then soldered between the notches 30a and 27a. A parallel diode 31 can also be soldered between the notches 26a and 27a. In addition, additional components can be accommodated in the relay chamber and connected to the various connections. For example, a parallel diode 32 is provided between the two conductor rails 24 and 25, which is clamped or soldered in corresponding notches 24d and 25d of these conductor rails.

Außerdem sind bei dem dargestellten Beispiel am Boden der Relaiskammer 6 zusätzliche Brückenschienen 33 und 34 angeordnet, die jeweils mit je einem Flachstecker 33a bzw. 33b und 34a bzw. 34b in jeden der beiden Steckerschächte 3 und 4 hineinreichen. Mit diesen Brücken können beispielsweise Sensorsignale vom Lastkreis zur Steuerung über die vorhandenen Mehrfachkabel durchgeschaltet werden. Die Flachstekker sind jeweils mit herausgeprägten oder angeschnittenen Rastnasen 35 versehen und auf diese Weise im Sockel so verankert, daß sie auch höhere Steckkräfte aufnehmen können.In addition, in the example shown, 6 additional bridge rails 33 and 34 are arranged on the bottom of the relay chamber, each of which extends into each of the two connector shafts 3 and 4, each with a flat plug 33a or 33b and 34a or 34b. With these bridges, for example, sensor signals can be switched through from the load circuit to the control via the existing multiple cables. The flat plugs are each with embossed or cut Provide locking lugs 35 and in this way anchored in the base so that they can also absorb higher insertion forces.

Bei der Montage werden die in FIG 2 gezeigten Einzelteile nacheinander in dem Sockel verankert und befestigt, gegebenenfalls auch verlötet. Dann wird die Kappe 7 übergestülpt, um die Relaiskammer 6 zu verschließen. Die Kappe 7 besitzt in ihrem Inneren angeformte Rippen 36 und 37, mit denen sie nach dem Verrasten mit dem Sockel auf entsprechende Ansätze 38 des Spulenkörpers drückt und somit zusätzlich das Magnetsystem fixiert. Durch Einbringen von Vergußmasse zwischen den Seitenwänden 5 und der Kappe 7 kann die Relaiskammer 6 dicht verschlossen werden. Soweit die Durchführungen 10 eine zusätzliche Abdichtung erfordern, kann auch der Boden der Relaiskammer oder der Boden in den Steckerschächten vorher oder im gleichen Arbeitsgang mit Vergußmasse ausgegossen werden.During assembly, the individual parts shown in FIG. 2 are anchored and fastened in the base one after the other, optionally also soldered. Then the cap 7 is put over to close the relay chamber 6. The cap 7 has integrally formed ribs 36 and 37 with which it presses on corresponding projections 38 of the coil body after it has latched with the base and thus additionally fixes the magnet system. By introducing potting compound between the side walls 5 and the cap 7, the relay chamber 6 can be sealed. As far as the bushings 10 require an additional seal, the bottom of the relay chamber or the bottom in the plug shafts can be filled with potting compound beforehand or in the same operation.

Zur Befestigung der Baugruppe dient außerdem ein Haltebügel 39, der mit seinem abgekröpften Unterteil 39a in einer am Sockel angeformten Aufnahmetasche 40 verrastet wird. Zweckmäßigerweise wird an beiden Längsseiten des Sockels eine solche Aufnahmetasche 40 vorgesehen, so daß die Baugruppe wahlweise in zwei verschiedenen Positionen befestigt werden kann.A mounting bracket 39 is also used to fasten the assembly, which is locked with its cranked lower part 39a in a receiving pocket 40 formed on the base. Such a receiving pocket 40 is expediently provided on both longitudinal sides of the base, so that the assembly can optionally be attached in two different positions.

FIG 3 zeigt in einer Ansicht von unten das Innere der beiden Steckerschächte 3 und 4. Anhand dieser Darstellung soll die Funktion der einzelnen Steckerelemente für das dargestellte spezielle Ausführungsbeispiel noch erläutert werden. Über den Steckerschacht 3 wird mit Hilfe eines siebenpoligen Steckverbinders die Verbindung der Relais-Baugruppe zur Steuerung und zur Spannungsquelle hergestellt. Die Erregerspannung wird über die beiden Flachstecker 26 und 27 angelegt, während die Lastspannung über den Stecker 21c anliegt. Der Massepol wird an den Stecker 25b angelegt und von diesem über die Schiene 25 zum Stecker 25c durchgeschleift. Zwischen dem Stecker 25c und 24b wird über einen vierpoligen Stecker im Steckerschacht 4 der Verbraucher, also beispielsweise ein Motor, angeschlossen. Der Stecker 24b verbindet dabei den zweiten Pol des Verbrauchers über die Schiene 24 mit der Kontaktfeder 22, so daß auf diese Weise beim Anziehen des Relais der Verbraucherkreis geschlossen wird. Über die Steckerstifte 34b und 35b werden vom Verbraucher Sensorsignale empfangen und über die Stekkerstifte 34a und 35a zur Steuerung durchgeschaltet. Zur Befestigung der in die Steckerschächte 3 und 4 eingesteckten Mehrfachsteckverbinder sind an dem Sockel zusätzliche Haltestege 41 angeformt, an denen entsprechende Rastelemente der Stecker eingreifen können.3 shows the inside of the two connector shafts 3 and 4 in a view from below. The function of the individual connector elements for the particular exemplary embodiment shown is to be explained on the basis of this illustration. The connection of the relay module to the control and to the voltage source is established via plug slot 3 with the help of a seven-pin connector. The excitation voltage is applied via the two flat plugs 26 and 27, while the load voltage is present via the plug 21c. The ground pole is applied to the connector 25b and looped through it via the rail 25 to the connector 25c. The consumer, for example a motor, is connected between the plugs 25c and 24b via a four-pole plug in the plug shaft 4. The plug 24b connects the second pole of the consumer via the rail 24 to the contact spring 22, so that the consumer circuit is closed in this way when the relay is energized. Sensor signals are received by the consumer via the plug pins 34b and 35b and switched through to the control via the plug pins 34a and 35a. To fasten the multiple plug connectors inserted into the plug shafts 3 and 4, additional holding webs 41 are formed on the base, on which corresponding latching elements of the plug can engage.
