Description

Die Erfindung bezieht sich auf ein Schütz mit Mitteln zum Ankoppeln eines zusätzlichen Schalterblockes, die aus quer zur Betätigungsrichtung einschiebbaren Hakenverbindungen und Rastmitteln sowie formschlüssiger Verbindung der Betä­tigungselemente bestehen.The invention relates to a contactor with means for coupling an additional switch block, which consist of hook connections and latching means which can be inserted transversely to the direction of actuation and a form-fitting connection of the actuating elements.

Bei einem bekannten Schütz der obengenannten Art (DE-OS 1 909 460) ist ein Elektromagnetgehäuse zur Aufnahme eines Betätigungsmagneten bekannt. Das Gehäuse bzw. der Elektro­magnet kann hier durch mehrere Kontaktgehäuseeinheiten, die jeweils feststehende Kontakte, bewegliche Kontakte und ein Betätigungselement für diese beweglichen Kontakte enthal­ten, zu einem Schütz komplettiert werden. Hierbei sind am Elektromagnetgehäuse und an den Kontaktgehäuseeinheiten quer zur Betätigungsrichtung einschiebbare Hakenverbindun­gen vorhanden. Federbelastete Stößel in den Kontaktgehäu­seeinheiten rasten hierbei in Ausnehmungen des Elektro­magnetgehäuses ein. Am Betätigungselement der beweglichen Kontakte der Kontaktgehäuseeinheiten ist ein Hammerkopf angeformt, in den entsprechende Arme des mit dem bewegli­chen Magneten verbundenen Betätigungselementes eingreifen. Bei dieser bekannten Anordnung sind die Anschlußelemente an den einzelnen Kontaktgehäuseeinheiten vorgesehen, und nur die Anschlüsse für die Betätigungsspule sind mit dem Elektromagnetgehäuse verbunden.In a known contactor of the type mentioned above (DE-OS 1 909 460), an electromagnet housing for receiving an actuating magnet is known. The housing or the electromagnet can be completed to form a contactor here by a plurality of contact housing units, each of which contains fixed contacts, movable contacts and an actuating element for these movable contacts. Hook connections that can be inserted transversely to the actuation direction are present on the electromagnet housing and on the contact housing units. Spring-loaded plungers in the contact housing units snap into recesses in the electromagnet housing. A hammer head is formed on the actuating element of the movable contacts of the contact housing units, into which corresponding arms of the actuating element connected to the movable magnet engage. In this known arrangement, the connection elements are provided on the individual contact housing units, and only the connections for the actuating coil are connected to the electromagnet housing.

Durch die Erfindung soll ein Schütz geschaffen werden, das es ermöglicht, zusätzlich zu bereits integrierten Schalt­kontakten weitere zusätzliche Kontakte als Block, insbe­sondere bei Schützen, deren Betätigungsrichtung der Kon­takte parallel zur Befestigungsebene verläuft, auf einfa­ che Weise ansetzen und entfernen zu können. Dies wird auf einfache Weise bei einem Schütz der obengenannten Art da­durch erreicht, daß im Schütz die Anschlußelemente für be­reits integrierte Schaltkontakte an der der Befestigungs fläche gegenüberliegenden Seite angeordnet sind und daß der zusätzliche Schalterblock an einer quer zur Betätigungs­richtung der Kontakte des Schützes liegenden Seitenfläche befestigbar ist und die formschlüssige Verbindung aus einer die Schaltstellungsanzeige an der Frontseite des Schützes ringförmig umgreifenden Anformung des Betäti­gungselementes des zusätzlichen Schalterblockes besteht. Der zusätzliche Schalterblock kann hierbei vorzugsweise den gleichen Querschnitt aufweisen wie der Querschnitt des Schützes. Um auf zusätzliche Federn für die Rastmittel, wie beim Stand der Technik erforderlich, verzichten zu können, ist es weiterhin von Vorteil, wenn die Rastmittel aus am zusätzlichen Schalterblock angeformten, federnden Rastarmen bestehen. Eine einfache Handhabung der Rastarme, insbeson­dere beim Lösen des zusätzlichen Schalterblockes läßt sich erreichen, wenn Teile der Rastarme über die Außenkonturen des zusätzlichen Schalterblockes hinausragen. Auf das Zu­sammendrücken der Rastarme beim Ansetzen des zusätzlichen Schalterblockes kann verzichtet werden, wenn die Rastarme parallel zur Betätigungsrichtung des Schützes verlaufen und keilförmige Rastnasen derart aufweisen, daß beim Verbinden des zusätzlichen Schalterblockes mit dem Schütz die Ver­rastung erfolgt.The invention is intended to provide a contactor which, in addition to already integrated switching contacts, makes it possible to add additional contacts as a block, in particular for contactors whose direction of actuation of the contacts runs parallel to the mounting plane be able to attach and remove. This is achieved in a simple manner in a contactor of the type mentioned above in that the connecting elements for already integrated switching contacts are arranged on the side opposite the mounting surface in the contactor and that the additional switch block can be fastened to a side surface lying transversely to the actuating direction of the contacts of the contactor and the form-fitting connection consists of a shaping of the actuating element of the additional switch block that encircles the switching position indicator on the front of the contactor. The additional switch block can preferably have the same cross section as the cross section of the contactor. In order to be able to dispense with additional springs for the latching means, as is required in the prior art, it is also advantageous if the latching means consist of resilient latching arms molded onto the additional switch block. Easy handling of the locking arms, in particular when releasing the additional switch block, can be achieved if parts of the locking arms protrude beyond the outer contours of the additional switch block. There is no need to press the locking arms together when attaching the additional switch block if the locking arms run parallel to the direction of actuation of the contactor and have wedge-shaped locking lugs such that the locking takes place when the additional switch block is connected to the contactor.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben.An exemplary embodiment according to the invention is described with reference to the drawing.

Das Schütz oder elektromagnetische Schaltgerät 1 besteht aus dem unteren Gehäuseteil 2 und dem Deckteil 3. Im unte­ren Gehäuseteil ist der Magnetantrieb, der nicht näher dargestellt ist, untergebracht und im Deckteil die Kon­taktanordnung mit den Flachsteckanschlüssen 4 für die feststehenden Kontaktteile, die über Kontaktbrücken ver­bindbar sind, sowie der das Betätigungselement 5 oder Kontaktbrückenträger für die beweglichen Kontaktbrücken bildende Teil mit der Schaltstellungsanzeige 6. Am unteren Gehäuseteil 2 zur Halterung des Schützes auf einer Trag­schiene 7 an gegenüberliegenden Seiten federnd nachgiebige Streifen 8 befestigt, die über Rasthaken 9 die Verbindung des unteren Gehäuseteils mit der Tragschiene 7 herstellen. Diese federnden Streifen können auf beiden Seiten des unte­ren Gehäuseteils 2 vorgesehen werden, so daß ein Abnehmen des Schützes von beiden Seiten möglich ist. Zur Verbindung mit einem zusätzlichen Schalterblock 10 dienen Haken 11 und 12, die etwa an den vier Ecken eines Rechteckes aus einer Seitenwand des Gehäuses des Schalterblockes herausragen, von denen die Haken 11 der Befestigungsebene, d.h. der Tragschiene 7 zugewandt und die Haken 12 am Rand der Stirn­seite des Schalterblockes angeformt sind. Den Haken 11 und 12 angepaßt sind gestrichelt angedeutete Durchbrüche 13 bzw. Ausnehmungen 14 im unteren Gehäuseteil 2 bzw. im Deck­teil 3 des Schützes 1 eingebracht, so daß der zusätzliche Schalterblock 10 nach Bewegung in Richtung des Pfeiles 15 zur Anlage an der einen Seitenfläche des Schützes 1 kommt. Durch Verschieben in Richtung des Pfeiles 16, d.h. eine Seitenfläche des Schützes 1 und eine Seitenfläche des Schalterblockes 10 gleiten aufeinander, werden die Haken wirksam. Um ein Zurückrutschen des Schalterblockes zu verhindern, sind Rastarme 17 vorhanden, die an das Gehäuse angeformt sind und leicht federn. An den füreien Enden der Arme 17 sind keilförmige Rastnasen 18 angeformt, die beim Verschieben des Schalterblockes 10 in Richtung des Pfeiles 16 hinter dem Rand jeweils einer Ausnehmung 19 verrasten. Das freie Ende der Rastarme 17 liegt beim Ansetzen an der Innenwandung 20 des Deckteils 3 an, so daß ein Spannen der Rastarme beim Einsetzen nicht notwendig ist. Zum Lösen die­nen Ausbuchtungen 21 der Rastarme 17, die über die Außen­kontur des Schalterblockes 10 hinausragen und leicht mit Daumen und Zeigefinger erfaßt werden können. An der Stirn­seite hat der Schalterblock 10, wie auch das Schütz selbst, Flachsteckanschlüsse 4 für die feststehenden Kontaktteile. Mit dem Betätigungselement 22 des Schalterblockes 10 ist ein Ring 23 verbunden, der beim Einschieben des Blockes 10 in Richtung des Pfeiles 16 mit der Schaltstellungsanzeige 6 formschlüssig zusammengeführt wird, so daß eine im wesent­lichen spielfreie Kupplung zwischen den Betätigungselemen­ten 5 und 22 erfolgt. Da sowohl das Schütz 1 als auch der Schalterblock 10 gleichen Querschnitt haben, ergibt sich nach Ansetzen des Schalterblockes 10 ein einheitlicher Ge­räteblock. Eine gesonderte Befestigung an der Tragschiene 7 ist nicht erforderlich. Als besonders vorteilhaftes Anwen­dungsgebiet für den Gegenstand der Erfindung hat sich das Gebiet der Hausgeräteschütze herausgestellt.The contactor or electromagnetic switching device 1 consists of the lower housing part 2 and the cover part 3. In the lower housing part the magnetic drive, which is not shown in more detail, is housed and in the cover part the contact arrangement with the flat plug connections 4 for Fixed contact parts, which can be connected via contact bridges, as well as the part forming the actuating element 5 or contact bridge support for the movable contact bridges with the switching position indicator 6. On the lower housing part 2 for holding the contactor on a mounting rail 7 on opposite sides, resilient strips 8 are fastened which Snap hook 9 establish the connection of the lower housing part with the mounting rail 7. These resilient strips can be provided on both sides of the lower housing part 2, so that the contactor can be removed from both sides. For connection to an additional switch block 10 are hooks 11 and 12, which protrude approximately at the four corners of a rectangle from a side wall of the housing of the switch block, of which the hooks 11 face the mounting level, ie the mounting rail 7 and the hooks 12 on the edge of the The face of the switch block are molded. The hooks 11 and 12 are shown with dashed openings 13 or recesses 14 in the lower housing part 2 or in the cover part 3 of the contactor 1, so that the additional switch block 10 after movement in the direction of arrow 15 to rest on one side surface of the contactor 1 is coming. By moving in the direction of arrow 16, ie a side surface of the contactor 1 and a side surface of the switch block 10 slide on each other, the hooks become effective. In order to prevent the switch block from sliding back, latching arms 17 are provided, which are molded onto the housing and spring slightly. At the free ends of the arms 17 wedge-shaped locking lugs 18 are formed, which each latch a recess 19 when the switch block 10 is moved in the direction of arrow 16 behind the edge. The free end of the locking arms 17 abuts against the inner wall 20 of the cover part 3 so that it is not necessary to tension the locking arms during insertion. Bulges 21 of the latching arms 17, which protrude beyond the outer contour of the switch block 10 and are easily used, are used for releasing Thumb and index finger can be grasped. On the front side, the switch block 10, like the contactor itself, has flat plug connections 4 for the fixed contact parts. With the actuating element 22 of the switch block 10, a ring 23 is connected which, when the block 10 is pushed in in the direction of the arrow 16, is positively brought together with the switch position indicator 6, so that an essentially backlash-free coupling takes place between the actuating elements 5 and 22. Since both the contactor 1 and the switch block 10 have the same cross-section, a uniform device block results after the switch block 10 is attached. A separate attachment to the mounting rail 7 is not necessary. The field of domestic appliance shooters has proven to be a particularly advantageous field of application for the subject matter of the invention.
