Description

Die Erfindung betrifft eine elektrische Steckverbindung nach dem Oberbegriff des Anspruchs 1The invention relates to an electrical connector according to the preamble of claim 1

Derartige Steckverbindungen, z.B. im sogenannten "M-" Standard (M6, M8 oder M12) sind an sich bekannt. Sie weisen den Nachteil auf, dass zum Verbinden und insbesondere auch Lösen durch die Notwendigkeit des Verschraubens relativ viel Zeit vergeht.Such connectors, e.g. in the so-called "M" standard (M6, M8 or M12) are known per se. They have the disadvantage that for connecting and in particular loosening by the necessity of screwing relatively long time passes.

Dieses Problem soll durch die Erfindung in einfacher Weise behoben werden.This problem should be solved by the invention in a simple manner.

Die Erfindung löst dieses Problem durch den Gegenstand des Anspruchs 1.The invention solves this problem by the subject matter of claim 1.

Sie schafft eine elektrische Steckverbindung, die folgendes aufweist: ein Steckerteil mit einem Außengewinde und ein hiermit korrespondierendes Buchsenteil, das ein Einrastmittel in Form wenigstens einer oder mehrerer Federzungen aufweist, welche zur Mittelachse des Gegenstücks auslenkbar sind und im zusammengesteckten Zustand der Steckverbindung zum Eingriff in das Außengewinde des Steckerteils dienen, und ein Schnellentriegelungsmittel, welches als axial verschieblicher Lösering ausgebildet ist, der derart ausgelegt und angeordnet ist, dass mit ihm die wenigstens eine Federzunge aus ihrer Verriegelungsstellung lösbar ist.It provides an electrical connector comprising: a male part having an external thread and a female part corresponding thereto, which has a latching means in the form of at least one or more spring tongues, which are deflectable to the central axis of the counterpart and in the assembled state of the connector for engaging in the External thread of the male part serve, and a quick release means, which is designed as an axially displaceable release ring, which is designed and arranged such that with him the at least one spring tongue from its locking position is releasable.

Die Federzunge gewährleistet, dass die beiden Steckverbinderteile lediglich axial zusammenzuschieben sind, um miteinander verbunden zu werden. Der Lösering gewährleistet eine Schnellentriegelung vorzugsweise allein durch eine Schiebebewegung.The spring tongue ensures that the two connector parts are merely pushed together axially to be connected to each other. The release ring ensures a quick release preferably solely by a sliding movement.

Schnellentriegelungen sind zwar an sich bekannt, so aus der EP 0 915 534 B1 . Es ist aber nicht die besonders vorteilhafte Kombination bekannt, nach welcher das Schnellverriegeln mittels einer Federzunge realisiert wird, die in ein Außengewinde eingreift und dann die Schnellentriegelung durch eine axial verschiebliche Hülse zu gewährleisten, die dazu ausgelegt ist, auf die Hülse einzuwirken.Quick releases are known per se, so from the EP 0 915 534 B1 , However, it is not the particularly advantageous combination known, after which the quick locking is realized by means of a spring tongue which engages in an external thread and then to ensure the quick release by an axially displaceable sleeve which is adapted to act on the sleeve.

Vorzugsweise ist der Lösering preiswert und einfach in Form einer Kreisringscheibe ausgeführt, die ein Rohrstück aufweist, welches sich von der Innenseite der Kreisringscheibe axial in die Aufnahme des Buchsenteils erstreckt.Preferably, the release ring is inexpensive and simply designed in the form of a circular disk, which has a piece of pipe which extends axially from the inside of the annular disk into the receptacle of the socket part.

Eine besonders gute Handhabbarkeit resultiert aus dem Merkmal, dass das Rohrstück an seinem von der Kreisringscheibe abgewandten Ende eine vollwinklig, außen umlaufende Wulst aufweist.A particularly good handling results from the feature that the pipe section has at its end facing away from the annular disk end a full-angled, outer circumferential bead.

Es bietet sich an, wenn das Rastmittel als Blechstanzbiegeteil ausgebildet ist.It is advisable if the locking means is designed as a sheet metal stamped and bent part.

Ein Ausführungsbeispiel der Erfindung ist in den beigefügten Zeichnungen dargestellt und wird im Folgenden näher beschrieben: Es zeigen:

Figur 1
eine schematische Darstellung einer Steckverbindung im eingesteckten Zustand (Stecker- und Buchsenteil befinden sich vollständig im Eingriff);
Figur 2
eine perspektivische Darstellung der Steckverbindung aus Fig. 1 im geöffneten Zustand (Stecker- und Buchsenteil sind nicht im Eingriff); und
Figur 3
eine perspektivische Darstellung der Einzelteile der Steckverbindung.
An embodiment of the invention is illustrated in the accompanying drawings and will be described in more detail below: In the drawings:
FIG. 1
a schematic representation of a plug connection in the inserted state (plug and socket part are fully engaged);
FIG. 2
a perspective view of the connector of Figure 1 in the open state (plug and socket are not engaged). and
FIG. 3
a perspective view of the items of the connector.

Figur 1 zeigt eine Steckverbindung 1 mit einem Steckerteil 2 mit ersten elektrischen Kontakten (hier nicht dargestellt) und einem hiermit zusammensteckbaren Buchsenteil 3 mit zweiten, korrespondierenden elektrischen Kontakten 9 in einem zentrischen Dom 10.FIG. 1 shows a plug connection 1 with a plug part 2 with first electrical contacts (not shown here) and a socket part 3 which can be plugged together herewith with second, corresponding electrical contacts 9 in a centric dome 10.

Nach Fig. 1 befindet sich dass Steckerteil 2 vollständig im Eingriff mit dem Buchsenteil 3. Ein O-Ring 7 im Buchsenteil 3 bildet für das Steckerteil axial, in Einsteckrichtung einen Endanschlag.According to FIG. 1, the plug part 2 is completely in engagement with the socket part 3. An O-ring 7 in the socket part 3 forms an end stop for the plug part axially, in the plug-in direction.

Das Steckerteil weist ein Außengewinde 6 auf, das an sich zur Verbindung mit einem korrespondierenden Buchsenteil mit einem Innengewinde an einer Mutter ausgelegt ist. Hier weist dass Buchsenteil 3 dagegen wenigstens eine radial vorkragende Federzunge 5 als Rastmittel zum Eingriff in das Außengewinde 6 des Steckerteils 2 auf. Die Federzungen erstrecken sich derart geneigt zur Mittelachse A des Buchsenteils 3, dass sie beim Einschieben des Steckerteils 2 in das Buchsenteil 3 radial nach außen federn, so dass das Steckerteil in das Buchsenteil 3 eingeschoben aber nicht wieder gegen die Rastwirkung der Federzunge 5 herausgezogen werden kann.The plug part has an external thread 6, which is designed to be connected to a corresponding female part with an internal thread on a nut. Here, however, that bushing part 3 has at least one radially projecting spring tongue 5 as latching means for engagement in the external thread 6 of the plug part 2. The spring tongues extend inclined to the central axis A of the female part 3 so that they spring radially outwardly upon insertion of the male part 2 into the female part 3, so that the male part can be inserted into the female part 3 but can not be pulled out against the locking action of the spring tongue 5 again ,

Soll die Steckverbindung 1 gelöst werden, geschieht dies einfach und schnell durch einen axialen Druckimpuls auf einen Lösering 4. Hierdurch werden die Federzungen 5 des Rastmittels radial nach außen gedrückt. Die Sperrung der Steckerteils 2 wird so freigegeben. Gleichzeitig wird das Steckerteil 2 axial, entgegen der Einsteckrichtung, aus dem Buchsenteil 3 gezogen.If the connector 1 are released, this is done simply and quickly by an axial pressure pulse on a release ring 4. As a result, the spring tongues 5 of the locking means are pressed radially outward. The blocking of the plug part 2 is released. At the same time, the plug part 2 is pulled axially, counter to the insertion direction, out of the socket part 3.

Die Betätigung des Löserings 4 kann mit der Hand erfolgen. Herrschen beengte Platzverhältnisse, so lässt sich der Lösering 4 auch mittels eines geeigneten Werkzeugs, beispielsweise mit einem Schraubendreher oder dgl., betätigen.The actuation of the release ring 4 can be done by hand. If cramped space conditions prevail, then the release ring 4 can also be actuated by means of a suitable tool, for example with a screwdriver or the like.

Fig. 2 zeigt eine perspektivische Schnittdarstellung durch die Mittelachse des Steckerteils 2 und des Buchsenteils 3 im entriegelten Zustand. Deutlich erkennbar ist der erfindungsgemäße Lösering 4 mit einer Kreisringscheibe 4a, die flanschartig an eine Innenhülse 4b angeformt ist und auch als Axialanschlag beim Einschieben dient. Ein innerer gestufter Ring 8 im Buchsenteil sichert den Lösering 4 an einem Bund 4c gegen ein Ausziehen aus dem Buchsenteil 3.Fig. 2 shows a perspective sectional view through the central axis of the plug part 2 and the female part 3 in the unlocked state. Clearly visible is the release ring 4 according to the invention with a circular disk 4a, which is integrally formed on an inner sleeve 4b and also serves as an axial stop during insertion. An inner stepped ring 8 in the socket part secures the release ring 4 on a collar 4c against being pulled out of the socket part 3.
