Modul-Steckverbinder sind aus dem Stand der Technik in verschiedener Form bekannt. Die US 5 411 413 zeigt einen Stecker mit einer Vielzahl von Anschlußkammern, die jeweils eine Mehrzahl von Crimpanschlüssen aufweisen.Module connectors are known in the art in various forms. US 5,411,413 shows a plug with a plurality of terminal chambers, the each having a plurality of crimp terminals.

Die DE 298 12 500 zeigt ein modulares Steckverbindersystem mit einem Buchsen- und einem Steckerteil, die jeweils einen Grundrahmen aufweisen, der mit einer im Querschnitt im wesentlichen U-förmigen Ausnehmung zur Aufnahme wenigstens eines mit Steckkontakten versehenen Einzelmoduls versehen ist. Das in dieser Schrift dargestellte Steckverbindersystem ist ferner mit einem Tragrahmen versehen, der längslaufende Rahmenleisten aufweist und mehrere Module enthält, die jeweils an einer ersten Längskante der Rahmenleisten abgestützt sind. Dabei sind Verriegelungselemente vorgesehen, die rastend oder klemmend an den Modulen montierbar sind und diese an einer zu der ersten Längskante entgegengesetzten zweiten Längskante blokkieren. Die Verriegelungselemente werden von Leisten gebildet, die sich über mehrere Module erstrecken und an jedem dieser Module angreifen. Dazu umfassen die Leisten Vorsprünge, welche in entsprechende Ausnehmungen der Module einfassen.DE 298 12 500 shows a modular connector system with a socket and a plug part, each having a base frame, with a cross-section essentially U-shaped recess for receiving at least one with Plug contacts provided individual module is provided.

The locking elements are formed by strips that extend over several Extend modules and attack on each of these modules. These include the last Projections which enclose in corresponding recesses of the modules.

Der Modul-Halterahmen kann theoretisch auch zur Aufnahme von Buchsen- und Stekkerteilen dienen, welche im Modul-Halterahmen nach Art eines Steckverbinders zusammengesteckt werden. Aus dem Stand der Technik ist es ferner bekannt, für die zu den Steckverbinderteilen geführten Leitungen Zugentlastungsvorrichtungen vorzusehen, die am Modul-Halterahmen oder Steckverbinder verriegelt werden.The module support frame can theoretically also for receiving socket and Stekkerteilen serve, which put together in the module holding frame in the manner of a connector become. From the prior art it is also known for the provide strain relief devices to the connector parts, which are locked to the module support frame or connector.

Ausgehend von diesem Stand der Technik setzt die Erfindung beim Erkennen der Möglichkeit an, die Zugentlastungsvorrichtung für Modulsysteme mit modularen Steckverbinderteilen derart weiterzuentwickeln, daß sie eine besonders einfache Handhabung auch der Steckverbinderteile erlaubt.Based on this prior art, the invention sets in recognizing the Possibility to use the strain relief device for modular systems with modular Further develop connector parts such that they are particularly simple Handling also the connector parts allowed.

Die Erfindung schafft daher den Gegenstand des Anspruches 1. Die Erfindung setzt bei der Idee an, die Zugentlastungsvorrichtung nicht nur zur Zugentlastung einzusetzen sondern auch derart einfach am Modul-Halterahmen anzuordnen, daß die Ent- und Verriegelung der Zugentlastungsvorrichtung am Modul nicht nur die Zugentlastung der Steckverbinderteile sichert, sondern diese bei ihrer Handhabung mit am Modul-Halterahmen ver- und entriegelt. Dazu sind die Verriegelungsmittel des Aufsatzelementes derart ausgebildet, daß sie sowohl mit den Verriegelungsmitteln des Modul-Halterahmens als auch mit den Verriegelungselementen des Steckverbinderteiles so zusammenwirken, daß das Aufsatzelement und das Steckverbinderteil am Modul-Halterahmen gemeinsam ver- und entriegelbar sind. The invention therefore provides the subject matter of claim 1. The invention sets at the idea of using the strain relief device not only for strain relief but also so easy to arrange on the module holding frame that the Ent- and locking the strain relief device on the module not only the strain relief the connector parts secures, but these in their handling with the module-holding frame locked and unlocked. These are the locking means of the attachment element formed so that they both with the locking means of the module-holding frame as well as with the locking elements of the connector part so cooperate, that the attachment element and the connector part on the module holding frame can be locked and unlocked together.

Nach einer Variante der Erfindung weist das Aufsatzelement hebelartige, im zusammengesetzten Zustand der Modulverriegelungsvorrichtung am Steckverbinder schwenkbar gelagerte Schwenkarme auf, welche mit den Verriegelungsmitteln zum Ver- und ein Entriegeln des Aufsatzelementes und des Steckverbinderteiles am Modul-Halterahmen versehen sind. Auf diese Weise wird eine kombinierte Zugentlastungs- und Verriegelungsvorrichtung geschaffen, welche die Handhabung des Steckverbinders bzw. das Ver- und Entriegeln des Steckverbinderteiles am Modul-Halterahmen entscheidend vereinfacht.According to a variant of the invention, the attachment element lever-like, in the composite Condition of the module locking device on the connector pivotally mounted pivot arms, which with the locking means for Locking and unlocking of the attachment element and the connector part on the module holding frame are provided.

Eine besonders leicht herstellbare und damit kostengünstige Ausführungsform der erfindungsgemäßen Zugentlastungsvorrichtung zeichnet sich dadurch aus, daß die Verriegelungsmittel der Schwenkarme als Rasthaken ausgebildet sind, welche an den zum Modul-Halterahmen weisenden Enden der Schwenkarme liegen.A particularly easy to produce and therefore cost-effective embodiment of the invention Strain relief device is characterized in that the locking means the pivot arms are designed as latching hooks which are connected to the Module holding frame facing ends of the pivot arms are.

Vorzugsweise werden dabei die Rasthaken der Schwenkarme derart ausgebildet, daß sie im zusammengesetzten Zustand an den Steckverbindern ausgebildete Rasthaken mit Hinterschneidungen hintergreifen (bzw. außen umfassen) und mit diesen gemeinsam in Ausnehmungen für die Befestigung des Buchsen- oder Steckerteiles am Modul-Halterahmen eingreifen. Beim Aufsetzen der Zugentlastungsvorrichtung auf das Steckverbinderteil werden die Rasthaken der Schwenkarme am Steckverbinderteil durch das Hintergreifen der Rasthaken des Steckverbinderteiles fixiert. Bei einem Zusammendrücken der Schwenkarme werden dann die Rasthaken der Steckverbinderteile mit den Schwenkarmen mitbewegt, so daß durch ein Bewegen der Schwenkarme das Steckverbinderteil und die Zugentlastungsvorrichtung gemeinsam vom Modul-Halterahmen gelöst werden. Preferably, the latching hooks of the pivot arms are formed such that they formed in the assembled state on the connectors locking hooks with undercuts behind (or outside embrace) and with these together in recesses for the attachment of the female or male part to the module holding frame intervention. When placing the strain relief on the Connector part are the locking hooks of the pivot arms on the connector part fixed by the engagement behind the latching hook of the connector part. When squeezed The swing arms then become the snap hooks of the connector parts moved with the pivot arms, so that by moving the pivot arms the Connector part and the strain relief device together from the module holding frame be solved.

Zur einfacheren Handhabung ist es zweckmäßig, wenn die Schwenkarme an ihren vom Modul-Halterahmen abgewandten Ende Griffmulden aufweisen.For easier handling, it is expedient if the pivot arms at their from Module holding frame opposite end have recessed grips.

Nach einer weiteren bevorzugten Variante der Erfindung ist es ferner vorteilhaft, wenn die Schwenkarme derart mittels Federschenkeln am Aufsatzelement befestigt sind, daß sie durch die Federkraft automatisch in ihre Verriegelungsstellung verschwenkbar sind.According to a further preferred variant of the invention, it is also advantageous if the pivot arms are secured by means of spring legs on the attachment element, that they are automatically pivoted by the spring force in its locking position are.

Fig. 1 zeigt ein Steckverbindermodul mit einem Steckerteil 2 und einem Buchsenteil 4, die jeweils einen ungefähr rechteckigen Querschnitt aufweisen und mittels seitlicher Rasthaken 6 in seitlichen Öffnungen 8 eines Modul-Halterahmens 10 verrastbar sind. 1 shows a connector module with a plug part 2 and a socket part 4, each having an approximately rectangular cross-section and by means of lateral Latch hooks 6 can be latched in lateral openings 8 of a module holding frame 10.

An ihren vom Modul-Halterahmen 10 abgewandten Endbereichen sind auf die beiden Steckverbinderteile 2, 4 jeweils Zugentlastungsvorrichtungen 12 aufgesetzt.At their end remote from the module holding frame 10 end areas are on the two Connector parts 2, 4 each strain relief 12 placed.

Die einstückig aus Kunststoff gebildeten Zugentlastungsvorrichtungen 12 sind nach Fig. 2 als über die Steckverbinderteile 2, 4 schiebbare - im Querschnitt im wesentlichen u-förmige Aufsatzelemente ausgebildet, die jeweils eine Grundwandung 14 aufweisen, wobei die beiden seitlichen Schenkel des U von Schwenk- und Federarmen 16, 18 gebildet werden. Die Schwenkarme 16 sind im vom Modul-Halterahmen 10 abgewandten Bereich der Zugentlastungsvorrichtung über die Federarme 18 mit der Grundwandung 14 bzw. mit auf der Grundwandung 14 senkrecht stehenden Eckstegen 19 verbunden. Die Federarme 18 sind an die Eckstege 19 in den vom Modul-Halterahmen 10 abgewandten Enden der Grundwandung 14 angeformt und erstrecken sich von dort bis in den Ansatzbereich der Stützbeine 20 an den Innenwandungen der Schwenkarme 16.The one-piece formed from plastic strain relief devices 12 are after Fig. 2 as on the connector parts 2, 4 slidable - in cross-section substantially formed U-shaped attachment elements, each having a base wall 14, wherein the two lateral legs of the U of swivel and spring arms 16, 18 are formed. The pivot arms 16 are in the module holding frame 10th remote from the region of the strain relief device via the spring arms 18 with the Base wall 14 or with perpendicular to the base wall 14 corner webs 19 connected. The spring arms 18 are connected to the corner webs 19 in the module holding frame 10 opposite ends of the base wall 14 integrally formed and extend from there to the approach area of the support legs 20 on the inner walls of the Swing arms 16.

Im zusammengesetzten Zustand sind außen zu den Endkanten des Modul-Halterahmens 10 an die Schwenkarme 16 nach innen hin Stützbeine 20 angeformt, die beim Zusammendrücken der Schwenkarme 16 an Stege 22 gedrückt werden, welche an die Grundwandung 14 angeformt sind, auf dieser senkrecht stehen und obere Haken 24 aufweisen, welche den Steckverbinder 2, 4 einfassen und gegen ein Verschieben sichern. Zu dieser Verschiebesicherung trägt zusätzlich die Ausbildung einer Stufung 26 (siehe Fig. 2) in der Grundwandung 14 bei, an der jeweils die Gehäuse der Steckverbinderteile 2, 4 anliegen.In the assembled state are outside to the end edges of the module-holding frame 10 to the pivot arms 16 inwardly support legs 20 integrally formed, the are pressed on webs 22 when squeezing the pivot arms 16, which are formed on the base wall 14, stand vertically on this and upper hooks 24, which surround the connector 2, 4 and against displacement to back up. In addition to this displacement protection contributes to the formation of a grading 26 (see Fig. 2) in the base wall 14 at, in each case the housing of the connector parts 2, 4 abut.

Von den Außenseiten der Stufungen 26 erstrecken sich weitere Stege 28 senkrecht nach oben, welche im oberen Bereich mit den Schwenkarmen 16 verbunden sind. An die vorderen Enden der Schwenkarme sind sich nach innen hin erstreckende Rasthaken 30 mit Hinterschneidungen 32 angeformt, welche beim Aufschieben der Zugentlastungsvorrichtung auf eines der Steckverbinderteile 2, 4 dessen Rasthaken 6 übergreifen. Gleichzeitig legt sich das Gehäuse des Steckverbinderteiles in die Stufung 16 sowie an die Stege 22. Durch das Zusammenspiel von Stufung 16, Stegen 22, Haken 24 und Schwenkarm-Rasthaken 30 wird das Steckverbinderteil 2, 4 an der Zugentlastungsvorrichtung festgelegt und arretiert. Dabei legen sich ferner die Stege 28 an die Außenwandungen der Gehäuse der Steckerverbinders 2, 4 und bilden eine Drehachse für die Schwenkhebel 16, die an ihren vom Rasthaken abgewandten Enden mit Griffmulden 34 versehen sind. Dadurch werden bei einem Zusammendrücken der zwei einander gegenüberliegenden Schwenkarme 16a, 16b einer Zugentlastungsvorrichtung 12 jeweils nicht nur die Rasthaken 30 der Schwenkarme 16 nach außen bewegt sondern gleichzeitig auch die an Stege 35 angeformten Rasthaken 6 der Steckverbinderteile 2, 4.From the outsides of the gradations 26 further webs 28 extend vertically to the top, which are connected to the pivot arms 16 in the upper area. At the front ends of the pivot arms are inwardly extending latching hooks 30 with undercuts 32 formed, which when pushing the strain relief device on one of the connector parts 2, 4 overlap the latching hooks 6. At the same time, the housing of the connector part sets in the gradation 16 as well to the webs 22. By the interaction of gradation 16, webs 22, hooks 24 and swing arm latch hook 30, the connector part 2, 4 at the strain relief device set and locked. In addition, the webs 28 attach themselves to the Outer walls of the housing of the plug connector 2, 4 and form an axis of rotation for the pivot lever 16, which faces away from the latching hook ends with recessed grips 34 are provided. This will be at a compression of the two opposing pivot arms 16a, 16b of a strain relief device 12 each not only the locking hooks 30 of the pivot arms 16 moves outward but at the same time integrally formed on webs 35 latch hooks 6 of the connector parts 2, 4.

Auf diese Weise ist es möglich, ohne zusätzliche Werkzeuge einfach durch Betätigung der Schwenkarme 16 auch die Rasthaken 6 der Steckverbinderteile mit nach außen zu ziehen, so daß Zugentlastungsvorrichtung gemeinsam durch ein Zusammendrücken der Schwenkarme 16 aus den Öffnungen 8 des Modul-Halterahmens gelöst werden. Zum Verriegeln der beiden Elemente (16 und 2 oder 4) ist es lediglich notwendig, die Zugentlastungsvorrichtung 12 und das Steckverbinderteil 2, 4 gemeinsam in den Modul-Halterahmen 10 zu schieben, so daß die Rasthaken 6, 30 durch Federkraft gemeinsam in die Öffnung 8 gedrückt werden.In this way it is possible without additional tools simply by pressing the pivot arms 16 and the latching hooks 6 of the connector parts with outward to Pull, so that strain relief device together by squeezing the pivot arms 16 are released from the openings 8 of the module holding frame. To lock the two elements (16 and 2 or 4), it is only necessary, the Strain relief device 12 and the connector part 2, 4 together in the module-holding frame 10, so that the latching hooks 6, 30 by spring force in common be pressed into the opening 8.

Zur Gewährung der Zugentlastungsfunktion ist die Grundwandung 14 mit fünf nebeneinanderliegenden Öffnungen 36 zur Durchführung von (hier nicht dargestellten) Kabel-Befestigungsbändern zur Zugentlastung eines zum Steckverbinderteil geführten elektrischen Leiters (hier ebenfalls nicht dargestellt) versehen. Zwischen den Öffnungen sind Riffelungen 38 zur Erhöhung der Reibung zwischen dem Leiter und der Grundwandung 14 und damit zur Verbesserung der Zugentlastungsfunktion ausgebildet.To grant the strain relief function is the base wall 14 with five adjacent Openings 36 for the passage of (not shown here) cable mounting straps for strain relief of a connector part led electrical conductor (also not shown here) provided. Between the openings are corrugations 38 to increase the friction between the conductor and the Base wall 14 and thus designed to improve the strain relief function.

Fig. 3 veranschaulicht die Erfindung anhand verschiedener perspektivischer Darstellungen eines Steckverbindermodules mit Zugentlastungsvorrichtung 12, wobei hier keine Federarme 18 zur Verbindung der Schwenkarme 16 mit der Grundwandung 14 vorgesehen sind und die Stützbeine 20 gleichzeitig als Drehlager für die Schwenkbewegungen der Schwenkarme 16 dienen. Gut zu erkennen sind auf den Modul-Halterahmen 10 aufgeschobene Montagewinkel 40 mit einer Aufnahmenut 42 für eine schwalbenschwanzartige Führungsschiene 44 am Modul-Halterahmen 10.Fig. 3 illustrates the invention with reference to various perspective views a connector module with strain relief device 12, wherein here no spring arms 18 for connecting the pivot arms 16 to the base wall 14th are provided and the support legs 20 at the same time as a pivot bearing for the pivoting movements serve the pivot arms 16.
