Abstract
Description
Die Erfindung betrifft ein elektromagnetisches Relais mit einem Grundkörper, welcher jeweils direkt oder indirekt ein Elektromagnetsystem mit einer Spule, einem Kernjoch sowie einem Anker, ferner eine von dem Anker betätigbare Kontaktanordnung sowie Anschlußleiter für die Kontaktanordnung und die Spule trägt, und mit einer auf den Grundkörper aufsteckbaren Kappe, wobei zumindest ein Teil der Anschlußleiter mit durch die Kappe nach außen geführten Kappen-Anschlußfahnen verbunden ist.The invention relates to an electromagnetic relay with a Basic body, which each directly or indirectly Electromagnetic system with a coil, a core yoke and one Anchor, furthermore a contact arrangement which can be actuated by the anchor as well as connecting conductors for the contact arrangement and carries the coil, and with one that can be plugged onto the base body Cap, with at least part of the connecting conductor with cap connecting lugs led through the cap to the outside connected is.
Aus der EP-A2-0 409 613 ist ein derartiges Relais bekannt, bei dem die Kontaktträger jeweils durch eine Bodenplatte geführte Lötanschlußstifte und zusätzlich durch Schlitze in einer Gehäusekappe nach außen geführte Flachsteckanschlüsse aufweisen. Damit diese Flachstecker bei der Montage der Kappe durch die vorgesehenen Schlitze geführt werden, muß sich ihre Längsachse in der Aufsteckrichtung erstrecken; außerdem müssen die Schlitze in der Kappe ein entsprechendes Spiel zum Toleranzausgleich gewährleisten. Da diese Flachstecker unmittelbar an den Kontaktträgern angeformt sind, fehlt auch eine mechanische Entkopplung zwischen den Kontaktelementen und den äußeren Steckkräften ausgesetzten Flachsteckern.Such a relay is known from EP-A2-0 409 613, in which the contact carriers each run through a base plate Solder pins and additionally through slots in one Housing cap tabs led to the outside exhibit. So that this flat connector when mounting the cap must be passed through the slots provided Extend the longitudinal axis in the direction of attachment; also need the slots in the cap match the game Ensure tolerance compensation. Because these tabs immediately are integrally formed on the contact carriers, one is also missing mechanical decoupling between the contact elements and the Flat connectors exposed to external insertion forces.
Ziel der vorliegenden Erfindung ist es, ein Relais der eingangs genannten Art konstruktiv so zu gestalten, daß Anschlußelemente im Kappenbereich an beliebigen Seiten vorgesehen werden können, die ein einfaches Aufstecken der Kappe gewährleisten, jedoch keine zusätzlichen Abdichtprobleme in der Kappe schaffen und, soweit es sich um Kontaktanschlüsse handelt, auch eine mechanische Entkopplung von den eigentlichen Kontaktträgern ermöglicht. The aim of the present invention is to provide a relay of the input mentioned type constructively so that connection elements provided in the cap area on any side that can be easily attached to the cap, however no additional sealing problems in the Create a cap and, as far as contact connections are concerned, also mechanical decoupling from the actual ones Allows contact carriers.
Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß in der Kappe elektrisch leitende Verbindungsstege befestigt sind, von denen jeder einerseits mit einer zur Kappenaußenseite vorstehenden Kappen-Anschlußfahne verbunden ist und andererseits im Kappeninneren ein Steckverbindungselement bildet, welches einem komplementären Steckverbindungselement eines Anschlußleiters auf dem Grundkörper gegenübersteht und mit diesem durch Aufstecken der Kappe in Eingriff gelangt.According to the invention this goal is achieved in that in the Cap electrically conductive connecting webs are attached, each one with one on the outside of the cap protruding cap connecting lug is connected and on the other hand forms a connector element inside the cap, which is a complementary connector element Connection conductor faces on the base body and with this comes into engagement by pushing on the cap.
Ein wesentliches Merkmal der Erfindung besteht also darin, daß die Kappen-Anschlußelemente nicht mit dem Grundkörper oder den im Grundkörper verankerten Anschlußelementen einstückig bzw. fest verbunden sind und so bei der Montage durch mehr oder weniger großzügig bemessene Öffnungen der Kappe gesteckt werden, sondern daß diese Anschlußfahnen fest mit der Kappe verbunden sind und bei deren Montage auf dem Grundkörper mit den dortigen Anschlußelementen automatisch kontaktiert werden. Dabei wäre es sogar denkbar, diese Kontaktierung als lösbare Steckverbindung auszubilden. Grundsätzlich jedoch handelt es sich dabei nicht um eine Steckverbindung, sondern um eine mehr oder weniger unlösbare Verbindung in Form von Klemmkontakten, die unter bleibender Verformung miteinander in Eingriff gebracht werden, so daß sie einander durchdringen und eine dauerhafte gasdichte Verbindung eingehen. Vorzugsweise sind also die Steckverbindungselemente nach Art einer Schneid-Klemmverbindung unlösbar miteinander verbunden, wie dies beispielsweise für die Anschlußkontaktierung von Steckverbindern üblich ist.An essential feature of the invention is therefore that the cap connection elements are not with the base body or the connecting elements anchored in the base body in one piece or are firmly connected and so during assembly more or less generous openings in the cap be, but that these connecting lugs firmly with the Cap are connected and when they are mounted on the base body automatically contacted with the connecting elements there become. It would even be conceivable to make this contact to be designed as a detachable plug connection. Basically however, this is not a plug connection, but about a more or less unsolvable connection in Form of clamping contacts that remain under permanent deformation with each other be engaged so that they are each other penetrate and form a permanent gas-tight connection. Preferably, the connector elements are after Type of insulation displacement connection permanently connected to each other, such as this for the connection contact of connectors is common.
Die Verbindungsstege können in einer vorteilhaften Ausführungsform entlang der Innenoberfläche der Kappe verlaufen und mit Befestigungsabschnitten dort befestigt sein. Dies kann beispielsweise mittels warmverformter Befestigungszapfen, durch Rastbefestigungen oder auf andere Weise geschehen. In einer anderen vorteilhaften Ausgestaltung können die Verbindungsstege zumindest teilweise in das Material der Kappe eingebettet sein. In jedem Fall kann die Durchführung der Kappen-Anschlußfahnen bereits bei der Herstellung der Kappe durch Einbetten oder bei der Vormontage der Kappen-Anschlußfahnen dicht ausgeführt werden, da beim Aufstecken der Kappe auf den Grundkörper keine Relativbewegung zwischen den Kappen-Anschlußfahnen und der Kappe selbst erforderlich ist.In an advantageous embodiment, the connecting webs can run along the inner surface of the cap and be fastened there with fastening sections. This can for example using thermoformed fastening pins, done by snap fasteners or otherwise. In Another advantageous embodiment, the connecting webs at least partially embedded in the material of the cap his. In any case, the implementation of the cap connection lugs already during the manufacture of the cap by embedding or pre-assembling the cap connection lugs be tight as they are plugged in the cap on the body no relative movement between the cap connecting lugs and the cap itself is.
Die Kappen-Anschlußfahnen können entweder als zusätzliche Anschlüsse für die Kontakte bzw. für die Spulenwicklung oder auch als einzige Anschlüsse vorgesehen sein. Entsprechend können die Anschlußleiter der Kontaktanordnung und/oder der Spule auch zusätzliche, vom Grundkörper nach außen geführte Sockel-Anschlußfahnen bilden.The cap tabs can either be used as additional connectors for the contacts or for the coil winding or also be provided as the only connections. Corresponding can the connecting conductors of the contact arrangement and / or Coil also additional, led outwards from the base body Form base connection lugs.
Soweit in diesem Zusammenhang davon die Rede ist, daß die komplementären Steckverbindungselemente gegenüber den Steckverbindungselementen der Kappe auf dem Grundkörper angeordnet sind, können diese natürlich auch in einem fest auf dem Grundkörper angeordneten Spulenkörper verankert sein. Denkbar wäre auch der Fall, daß ein Spulenkörper selbst einen die Anschlußleiter für die Kontakte tragenden Grundkörper bildet.Insofar as there is talk in this connection that the complementary connector elements compared to the connector elements the cap arranged on the base body are, of course, also in a fixed on the Base body arranged bobbin be anchored. Conceivable would also be the case that a bobbin itself the lead forms the basic body for the contacts.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel
anhand der Zeichnung näher erläutert. Es zeigt
Das in den Figuren 1 und 2 dargestellte Relais besitzt einen
bekannten Aufbau mit einem Sockel 1, auf dem ein Magnetsystem
mit einem Spulenkörper 2 als Träger für eine Wicklung 3, ferner
mit einem Kern 4, einem abgewinkelten Joch 5 und einem
Anker 6 angeordnet ist. In dem Sockel 1 bzw. einer mit ihm
verbundenen Seitenwand 7 sind jeweils Kontakt-Anschlußleiter
8 und 9 verankert, die jeweils zur Unterseite des Sockels 1
austretende Anschlußfahnen 10 (nur eine zu sehen) bilden. Der
Anschlußleiter 8 trägt einen nicht sichtbaren Festkontakt,
während der Anschlußleiter 9 über eine Litze 11 mit einer
Kontaktfeder 12 bzw. einem auf der Kontaktfeder befestigten
beweglichen Kontakt verbunden ist. Die Kontaktfeder ist mit
dem Anker verbunden und wird in üblicher Weise durch diesen
betätigt.The relay shown in Figures 1 and 2 has one
known structure with a base 1 on which a magnet system

Um zusätzlich zu den Sockel-Anschlußfahnen 10 einen parallelen
Abgriff des Laststromkreises zu ermöglichen, beispielsweise
für Diagnoseabfragen, für einen Leiterplattenanschluß
oder für sonstige Anwendungen, sind in einer Kappe 13, die
mit dem Sockel 1 ein geschlossenes Gehäuse bildet, zusätzlich
elektrisch leitende Verbindungsstege 14 und 15 für den Lastkreis
vorgesehen, die jeweils zur Kappenaußenseite vorstehende
Flachstecker 16 und 17 bilden. Außerdem sind in der Kappe
weitere Verbindungsstege 18 und 19 mit nach außen geführten
Flachsteckern 20 und 21 als Spulenanschlüsse vorgesehen. Alle
Verbindungsstege in der Kappe sind entlang der Innenoberfläche
geführt und mittels warmverprägter Zapfen 22 bzw. Haltestege
23 befestigt. Jeder der Verbindungsstege besitzt einen
gabelförmigen Klemmlappen 24 mit einem in Aufsteckrichtung
der Kappe offenen Schneidklemmschlitz. Die Klemmlappen 24 der
Verbindungsstege 14 und 15 liegen genau über entsprechenden
Klemmstegen 25 der Anschlußleiter 8 und 9, so daß sie mit
diesen beim Aufstecken der Kappe 13 jeweils eine Schneid-Klemmverbindung
eingehen.To a parallel to the
Die Klemmlappen 24 der Verbindungsstege 18 und 19 für die
Spulenanschlüsse kommen entsprechend über Klemmabschnitten 26
zu liegen, die jeweils Teil von zwei Anwickelstützen 27 und
28 für die Enden der Wicklung 3 sind. Die beiden Schneid-Klemmabschnitte
26 liegen jeweils auf gabelförmigen Stützen
29 des Sockels 1, damit sie beim Aufpressen der zugehörigen
Klemmlappen 24 dem Druck standhalten können, so daß eine feste
und dauerhafte Schneid-Klemmverbindung entsteht.The
Bei dem dargestellten Ausführungsbeispiel besitzt die Spulenwicklung
3 also nur Anschlüsse über die Verbindungsstege 18
und 19 sowie die Flachstecker 20 und 21, während die Kontakte
sowohl über Sockel-Anschlußfahnen 10 als auch über Kappen-Anschlußfahnen
16 und 17 verfügen. Bei Bedarf könnten natürlich
auch zusätzliche Spulenanschlußelemente im Sockel vorgesehen
werden.In the illustrated embodiment, the coil winding

es aber auch möglich, diese Verbindungsstege bereits bei
der Herstellung der Kappe in deren Wände einzubetten.The
In Figur 4 ist ein Schaltbild des dargestellten Relais mit
seinen Anschlüssen gezeigt. Daraus ist zu ersehen, daß der
Lastkreis der Kontakt-Anschlußleiter 8 und 9 jeweils über
parallel geschaltete Sockel-Anschlußfahnen 10 und Kappen-Anschlußfahnen
16 bzw. 17 anschließbar ist, während der Spulenkreis
