Abstract

Elektromagnetisches Schaltgerät mit einem Gehäuseoberteil und einer Bodenplatte Bei starrer Befestigung der Bodenplatte am Gehäuseoberteil eines elektromagnetischen Schaltgerätes sind bei starrer Befestigung Beschädigungen des Gehäuses und der Bodenplatte bzw. Prellungen des Magnetsystems zu befürchten. Man hat daher den nichtschaltenden Magnetteil bisher elastisch mit der Bodenplatte verbunden. Die Bodenplatte wird gegenüber dem Gehäuseoberteil elastisch nachgiebig gehalten, und zwar durch Zwischenschalten elastischer Dämpfungsglieder beim Anschrauben der Bodenplatte an das Gehäuseoberteil. Die Bodenplattenaufhängung eignet sich insbesondere für elektromagnetische Schaltgeräte, wie Schütze.Electromagnetic switchgear with an upper part of the housing and a base plate If the base plate is rigidly attached to the upper part of an electromagnetic switchgear, there is a risk of damage to the housing and the base plate or bruises of the magnet system if it is rigidly attached. Therefore, the non-switching magnetic part has so far been elastically connected to the base plate. The base plate is held elastically resilient with respect to the upper housing part, namely by interposing elastic damping elements when the base plate is screwed onto the upper housing part. The base plate suspension is particularly suitable for electromagnetic switching devices such as contactors.

Description

Die Erfindung bezieht sich auf ein elektromagnetisches Schalt­gerät mit in einem Gehäuseoberteil angeordneten, feststehen­den und mit einem beweglichen, in dem Gehäuseoberteil geführ­ten, schaltenden Magnetteil verbundenen beweglichen Kontakt­teil, sowie einer das Gehäuseoberteil abschließenden, mit die­sem verschraubten und den nichtschaltenden Magnetteil halten­den Bodenplatte.The invention relates to an electromagnetic switching device with fixed in a housing upper part and connected to a movable, guided in the housing upper, switching magnetic part movable contact part, as well as a bottom plate closing the housing upper part, screwed to it and holding the non-switching magnetic part.

Bei einem bekannten elektronischen Schaltgerät der obengenann­ten Art (DE-PS 24 15 489) stützen sich die die Bodenplatte mit dem Gehäuseoberteil verbindenden Schrauben über eine Scheibe und Sprengringe mit dem Kopf am Gehäuseoberteil ab. Das Gewin­de der Schrauben ist in entsprechende Gewindelöcher der Boden­platte eingedreht. Zwischen Gehäuseoberteil und Bodenplatte können jedoch Toleranzausgleichsstücke eingeschoben werden. Um Beschädigungen der Bodenplatte beim Schalten des Magneten zu verhindern, muß dies relativ stark ausgeführt werden. Bei starrer Ausführung der Bodenplatte und starrer Auflage des nichtschaltenden Magnetteils auf der Bodenplatte können jedoch Prellungen des Magnetsystems beim Schalten auftreten, die sich ebenfalls nachteilig auswirken können.In a known electronic switching device of the type mentioned above (DE-PS 24 15 489), the screws connecting the base plate to the upper housing part are supported by a washer and snap rings with the head on the upper housing part. The thread of the screws is screwed into the corresponding threaded holes in the base plate. However, tolerance compensation pieces can be inserted between the upper part of the housing and the base plate. To prevent damage to the base plate when switching the magnet, this must be done relatively strongly. If the base plate is of a rigid design and the non-switching magnetic part rests rigidly on the base plate, bruises of the magnet system can occur during switching, which can likewise have a disadvantageous effect.

Es ist zur Halterung eines kompletten Kontaktgehäuses bei Schützen auch bekannt (FR-A-1 406 946, GB-A-1 064 648) dieses Gehäuse auf einem Tragrahmen über ringförmige, elastische Ele­mente, durch die Bolzen gesteckt sind, zu befestigen.It is also known for mounting a complete contact housing for shooters (FR-A-1 406 946, GB-A-1 064 648) to fasten this housing on a support frame via ring-shaped, elastic elements through which bolts are inserted.

Der Erfindung liegt die Aufgabe zugrunde, eine Bodenplatten­aufhängung zu schaffen, mit der zumindest in gewissen Grenzen bei einfachem und kostengünstigem Aufbau Prellungen des Mag­netsystems vermieden werden. Dies wird auf einfache Weise da­ durch erreicht, daß den Schrauben elastisch nachgiebige Däm­pfungsglieder zugeordnet sind, die eine Bewegung der Boden­platte gegenüber dem Gehäuseteil zulassen. Hier können zusätz­liche Dämpfungselemente zwischen Magnetteil und Gehäuse ent­fallen. Um die Bodenplatte in Richtung Einschaltbewegung des Magnetsystems elastisch aufhängen zu können hat es sich als vorteilhaft erwiesen, wenn die Dämpfungsglieder aus Druckfe­dern bestehen, die sich einerseits direkt oder indirekt an den Schraubenköpfen und andererseits am Gehäuseoberteil ab­stützen und die Schraubengewinde in die Bodenplatte eingedreht sind, wobei dann vorteilhafterweise die Bodenplatte in einer Vertiefung des Gehäuseoberteils liegt, so daß die Befestigung des Gerätes an der Befestigungsfläche nicht beeinträchtigt wird. Wird die Druckfeder auf einer das Gewinde der Schraube übergreifenden, mit einem am Schraubenkopf direkt oder indi­rekt anliegenden Abstützungskragen für die Druckfeder versehe­nen Buchse geführt, deren dem Abstützungskragen abgewandtes Ende durch die Schraube an die Bodenplatte gepreßt ist, und wird die Druckfeder von den Schenkeln eines U-förmigen Hal­ters unter Vorspannung gehalten, deren einer Schenkel am Ge­häuseoberteil anliegt, so kann der Stoßdämpfer als komplette Einheit vormontiert werden und wie eine übliche Befestigungs­schraube eingeschraubt werden. Hierfür ist es weiterhin von Vorteil, wenn der Halter aus Kunststoff ist sowie wenn der Halter in eine angepaßte Öffnung im Gehäuseoberteil einge­legt ist, so daß auch der optische Eindruck der geschlosse­nen Oberfläche des Gehäuseoberteils nicht gestört wird. Auf einfache Weise lassen sich auch bei der erfindungsgemäßen Schaltgeräteausführung Toleranzausgleichsringe, wie beim Stand der Technik, als Zwischenlage einfügen. Sie können aber hier, im Gegensatz zum Stand der Technik, bei dem die Justierschei­ben mit Klauen an einem Haltesteg der Bodenplatte befestigt sind, mit der Schraube selbst als Einheit eingebracht werden.The invention has for its object to provide a base plate suspension with which bruises of the magnet system are avoided at least within certain limits with a simple and inexpensive construction. This will be there in a simple way achieved by that the screws are assigned resilient attenuators that allow movement of the base plate relative to the housing part. Additional damping elements between the magnetic part and the housing can be omitted here. In order to be able to suspend the base plate elastically in the direction of the switch-on movement of the magnet system, it has proven to be advantageous if the damping members consist of compression springs which are supported, on the one hand, directly or indirectly on the screw heads and, on the other hand, on the upper part of the housing and the screw threads are screwed into the base plate, whereby then advantageously the base plate lies in a recess of the upper housing part, so that the fastening of the device to the fastening surface is not impaired. If the compression spring is guided on a bushing which overlaps the thread of the screw and is provided with a support collar for the compression spring which is located directly or indirectly against the screw head and whose end facing away from the support collar is pressed against the base plate by the screw, and the compression spring is removed from the legs of a U -shaped holder held under pretension, one leg of which rests on the upper housing part, so the shock absorber can be preassembled as a complete unit and screwed in like a conventional fastening screw. For this purpose, it is also advantageous if the holder is made of plastic and if the holder is inserted into an adapted opening in the upper housing part, so that the visual impression of the closed surface of the upper housing part is not disturbed. Tolerance compensation rings, as in the prior art, can also be inserted as an intermediate layer in a simple manner in the switching device design according to the invention. However, in contrast to the prior art, in which the adjusting disks are fastened to a holding web of the base plate with claws, they can be introduced as a unit with the screw itself.

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 in der Zeichnung schematisch dargestellte Schaltgerät be­steht aus dem Gehäuseoberteil 1 und der mit diesem über Schrau­ben 2 verbundenen Bodenplatte 3. An der Bodenplatte 3 ist der nichtschaltende Magnetteil 4 mit der Erregerspule 5 fest ver­bunden. Im Gehäuseoberteil 1 sind die feststehenden Kontakte 8a befestigt und der mit dem schaltenden Magnetteil 6 verbun­dene Kontaktbrückenträger 7 für die Kontaktbrücken in übli­cher Weise gegen die Kraft einer Rückdruckfeder verschiebbar geführt. Zur Verbindung der Bodenplatte 3 mit dem Gehäuseober­teil 1 sind den Schrauben 2 elastisch nachgiebige Dämpfungs­glieder, im vorliegenden Fall Druckfedern 9, zugeordnet, die auf einer mit einem Abstützungskragen 10 versehenen Buchse 11 geführt sind. Die Buchse 11 ist durch eine Bohrung 12 im Ge­häuseoberteil 1 hindurchgeführt und liegt auf zwischen Gehäu­seoberteil 1 und Bodenplatte 3 eingelegten Toleranzausgleichs­scheiben 13 an. Der Abstützungskragen 10 stützt sich über eine Scheibe 14 am Schenkel 15 eine U-förmigen Halters 16 ab. Am anderen Schenkel 17, der in eine Gabel zum Einschieben der Buchse 11 ausläuft, stützt sich die Feder 9 ab, die mit ihrem anderen Ende am Abstützungskragen 10 anliegt. Der Schrauben­kopf 18 mit einem Federring 19 ist durch eine Öffnung 20 im Schenkel 15 hindurchgeführt. Zum Einsetzen der Schraube in den Halter 16 wird zunächst die schräggestellte Schraube mit dem Kopf 18 und dem Federring 19 durch die Öffnung 20 hin­durchgeschoben. Die Feder wird leicht gespannt, und durch Ver­schwenken um die Auflage der Scheibe 14 am Schenkel 15 wird die Buchse in die aus der Zeichnung ersichtliche Lage einge­schwenkt, so daß sich die Feder unter Vorspannung im Halter 16 abstützt und als komplettes Bauteil in eine Öffnung 21 im Gehäuseoberteil 1 eingelegt werden kann. Hierbei kommt die Buchse 11 durch die Bohrung 12, und das Gewinde der Schraube 2 wird in Gewindelöcher der Bodenplatte 3 eingedreht. Beim Schalten des Schaltgerätes schlägt der schaltende Magnetteil 6 auf den nichtschaltenden Magnetteil 4; die Schläge werden auf die Bodenplatte 3 übertragen. Ein Brechen der Bodenplatte und des Gehäuses ist ausgeschlossen, da sich die Druckfeder 9 zusammendrücken kann, so daß sich die Bodenplatte 3 vom Gehäu­seoberteil abheben kann. Hierzu ist am Boden des Gehäuseober­teils eine entsprechende Ausnehmung vorgesehen, so daß sich die Bodenplatte auch bei angeschraubtem Schaltgerät frei be­wegen kann. Bei der erfindungsgemäßen Bodenplattenaufhängung können somit zusätzliche Dämpfungselemente für den nichtschal­tenden Magnetteil entfallen. Die Dämpfung durch die Druckfeder 9 ist auf einfache Weise abzustimmen, und das Einsetzen des im Halter 16 vormontierten Bauteils bedingt keine besondere Fach­kenntnis und Sorgfalt, da hier jede beliebige Schraube ein­setzbar ist.The switching device shown schematically in the drawing consists of the upper housing part 1 and the base plate 3 connected to it via screws 2. The non-switching magnetic part 4 is firmly connected to the excitation coil 5 on the base plate 3. The fixed contacts 8a are fastened in the upper housing part 1 and the contact bridge carrier 7, which is connected to the switching magnetic part 6, is displaceably guided for the contact bridges in the usual manner against the force of a back pressure spring. To connect the base plate 3 to the upper housing part 1, the screws 2 are assigned elastically flexible damping members, in the present case compression springs 9, which are guided on a bushing 11 provided with a support collar 10. The bushing 11 is passed through a bore 12 in the upper housing part 1 and rests on tolerance compensating disks 13 inserted between the upper housing part 1 and the base plate 3. The support collar 10 is supported by a disk 14 on the leg 15 of a U-shaped holder 16. On the other leg 17, which ends in a fork for inserting the bushing 11, the spring 9 is supported, the other end of which rests on the support collar 10. The screw head 18 with a spring ring 19 is passed through an opening 20 in the leg 15. To insert the screw into the holder 16, the inclined screw with the head 18 and the spring ring 19 is first pushed through the opening 20. The spring is slightly tensioned, and by pivoting about the support of the disc 14 on the leg 15, the socket is pivoted into the position shown in the drawing, so that the spring is supported under tension in the holder 16 and as a complete component in an opening 21 in Upper housing part 1 can be inserted. Here, the bushing 11 comes through the bore 12, and the thread of the screw 2 is screwed into the threaded holes in the base plate 3. When switching the switching device, the switching magnetic part 6 strikes the non-switching magnetic part 4; the blows are transmitted to the base plate 3. The base plate and the housing cannot break because the compression spring 9 can compress so that the bottom plate 3 can stand out from the upper housing part. For this purpose, a corresponding recess is provided on the bottom of the upper housing part, so that the base plate can move freely even when the switching device is screwed on. With the base plate suspension according to the invention, additional damping elements for the non-switching magnetic part can thus be omitted. The damping by the compression spring 9 can be adjusted in a simple manner, and the insertion of the component preassembled in the holder 16 does not require any special expertise and care, since any screw can be used here.
