According to the invention, the connecting elements (1) are prevented from drifting towards the base plate when the individual contactors (6) are screwed thereto.

Description

Beschreibungdescription
Verbindungselernent zum Verbinden von Einzelschützen zu einer SchützkombinationConnection element for connecting individual contactors to a contactor combination
Die Erfindung bezieht sich auf ein Verbindungselernent zum Verbinden von Einzelschützen zu einer Schützkombination.The invention relates to a connecting element for connecting individual contactors to form a contactor combination.
Verbindungselemente für Schützkombinationen gehören seit ge- raumer Zeit zum Lieferprogramm von Schützherstellern. Bei den hierzu verwendeten Schützen sind die Magnetkammern mit Nuten, z.B. Schwalbenschwanznuten oder T-Nuten ausgeprägt. Die bekannten Verbindungselemente sind im Bereich von Hutschienenbefestigungen der Schütze positioniert. Auf diese Weise wer- den die Verbindungselemente gegen Herausfallen fixiert. Bei Verschraubung der Geräte auf einer Grundplatte ist ein Herauswandern der Verbindungselemente bis zur Grundplatte möglich.Connecting elements for contactor combinations have been part of the delivery program of contactor manufacturers for some time. In the contactors used for this purpose, the magnetic chambers are provided with grooves, e.g. Pronounced dovetail grooves or T-grooves. The known connecting elements are positioned in the area of the rail mountings of the contactors. In this way, the connecting elements are fixed against falling out. If the devices are screwed onto a base plate, the connection elements can move out to the base plate.
Die zunehmende Miniaturisierung der Schütze, insbesondere die Reduzierung der Baubreite, bringt es mit sich, daß durch die Platzverhältnisse in der Magnetkammer die mögliche Positionierung der Koppelstelle eingeschränkt wird. Wird die Koppelstelle außerhalb des Eingriffsbereichs der Hutschiene ge- wählt, muß ein Herauswandern des Verbindungselements zuverlässig verhindert werden.The increasing miniaturization of the contactors, in particular the reduction in the overall width, means that the space available in the magnetic chamber limits the possible positioning of the coupling point. If the coupling point is selected outside the area of engagement of the top-hat rail, migration of the connecting element must be reliably prevented.
Der Erfindung liegt die Aufgabe zugrunde, ein Verbindungselement zu schaffen, bei dem unabhängig von der Position in der Magnetkammer der Schütze und unabhängig von der Befestigungsart, z.B. Hutschienenbefestigung oder Aufschrauben auf einer Grundplatte, ein Herauswandern zuverlässig verhindert wird. Die Aufgabe wird durch ein Verbindungselement mit folgenden Merkmalen gelöst: a) Das Verbindungselement weist Eingriffsabschnitte zum Ein- schub in angepaßt gestaltete Eingriffsnuten der Schütze auf, b) das Verbindungselernent der Eingriffsabschnitte mit Rastnasen versehen, die zur Verrastung an den Einzelschützen nach Einschub der Eingriffsabschnitte in die Eingriffsnuten dienen, c) die Rastnasen sind an federnden Außenflächen des Verbindungselements angeformt .The invention has for its object to provide a connecting element, in which irrespective of the position in the magnetic chamber of the contactor and regardless of the type of mounting, for example top hat rail mounting or screwing onto a base plate, migration is reliably prevented. The task is solved by a connecting element with the following features: a) The connecting element has engagement sections for insertion into adapted engagement grooves of the contactors, b) the connecting element of the engagement sections is provided with latching lugs which serve for latching on the individual shooters after insertion of the engagement sections into the engagement grooves, c) the latching lugs are on resilient Molded outer surfaces of the connecting element.
Vorteilhafte Weiterbildungen des Verbindungselements sind den Unteransprüchen 2 und 3 zu entnehmen.Advantageous developments of the connecting element can be found in subclaims 2 and 3.
Ein Ausführungsbeispiel der Erfindung wird im folgenden an- hand einer Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail below with reference to a drawing. Show it:
FIG 1 eine perspektivische Ansicht eines Verbindungselements und FIG 2 das Verbindungselernent gemäß FIG 1 nach Verrastung in einem Einzelschütz.1 shows a perspective view of a connection element and FIG. 2 shows the connection element according to FIG. 1 after latching in a single contactor.
In FIG 1 ist eine perspektivische Ansicht eines Verbindungselements 1 zum Verbinden von Einzelschützen zu einer Schütz- kombination dargestellt. Das Verbindungselernent 1 weist T- förmige Eingriffsabschnitte 2 auf. Im Kopfbereich 3 ist das Verbindungselement 1 mit zwei federnden Schenkeln 4 ausgeführt, an deren Außenflächen Rastnasen 5 angeformt sind. Der Abstand a der Eingriffsabschnitte 2 ist dem Montageabstand der Einzelschütze angepaßt.1 shows a perspective view of a connecting element 1 for connecting individual contactors to form a contactor combination. The connection element 1 has T-shaped engagement sections 2. In the head region 3, the connecting element 1 is designed with two resilient legs 4, on the outer surfaces of which locking lugs 5 are formed. The distance a of the engagement sections 2 is adapted to the mounting distance of the individual contactors.
FIG 2 zeigt ein Verbindungselement 1 im verrasteten Zustand in einem Einzelschütz 6, von dem hier nur ein Teilbereich wiedergegeben ist. Die Koppelstelle befindet sich hier außerhalb der Hutschienenbefestigung 7 des Einzelschützes, das zur Ankopplung des Verbindungselements 1 eine angepaßt gestaltete Eingriffsnut 8 aufweist, die demzufolge auch T- förmig ausgebildet ist. Das Verbindungselernent 1 ist hier nach Einschub in die Eingriffsnut 8 über seine Rastnasen 4 an einer Gehäusekontur 9 des Einzelschützes 6 verrastet. Sowohl zum Einschub wie auch zur Demontage ist die Ausbildung mit den federnden Schenkeln 4 wichtig. Zur Demontage der Schützkombination wird das Verbindungselement 1 im Kopfbereich 3 mit einer Zange gegriffen und aus den Eingriffsnuten 8 der Magnetkammern der Einzelschütze 6 herausgezogen. Bei diesem Vorgang wird die Verrastung des Verbindungselements 1 automatisch entriegelt.2 shows a connecting element 1 in the locked state in a single contactor 6, of which only a partial area is shown here. The coupling point is here outside the top-hat rail mounting 7 of the single contactor, which is adapted for coupling the connecting element 1 designed engagement groove 8, which is therefore also T-shaped. The connecting element 1 is locked here after insertion into the engagement groove 8 via its locking lugs 4 on a housing contour 9 of the individual contactor 6. Training with the resilient legs 4 is important both for insertion and for disassembly. To dismantle the contactor combination, the connecting element 1 is gripped in the head region 3 with a pair of pliers and pulled out of the engagement grooves 8 of the magnetic chambers of the individual contactors 6. In this process, the locking of the connecting element 1 is automatically unlocked.
Je nach Montageabstand der Einzelschütze wird das Verbindungselement 1 mit entsprechend angepaßten Abstand a zwischen seinen Eingriffsabschnitten 2 ausgeführt.Depending on the mounting distance of the individual contactors, the connecting element 1 is designed with a correspondingly adjusted distance a between its engagement sections 2.
Obwohl die vorliegende Erfindung unter Bezugnahme auf die in der beigefügten Zeichnung dargestellte Ausführungsform erläutert ist, sollte berücksichtigt werden, daß damit nicht beab- sichtigt ist, die Erfindung nur auf die dargestellte Ausführungsform zu beschränken, sondern alle möglichen Änderungen, Modifizierungen und äquivalente Anordnungen, soweit sie vom Inhalt der Patentansprüche gedeckt sind, einzuschließen. Although the present invention is explained with reference to the embodiment shown in the accompanying drawing, it should be borne in mind that it is not intended to limit the invention to the embodiment shown, but rather all possible changes, modifications and equivalent arrangements, as far as they are covered by the content of the claims.
