Ein derartiger elektrischer Nullkraftsteckverbinder ist aus der deutschen Offenlegungsschrift DE 10 2005 040 952 A1 bekannt. Dieser Such a zero-force electrical connector is known from German patent application DE 10 2005 040 952 A1. This
Nullkraftsteckverbinder weist ein Steckhülsengehäuse mit zwei als Nullkraftsteckverbinder has a receptacle housing with two as
Umgehäuse und Fixiergehäuse bezeichneten Gehäuseteilen auf, die relativ zueinander zwei Raststellungen einnehmen können. Befinden sich die  Surrounding housing and fixing housing designated housing parts, which can assume two detent positions relative to each other. Are the
Gehäuseteile in einer ersten Raststellung, so halten mit dem Umgehäuse verbundene Spannhülsen die Hülsenkontakte geöffnet, so dass die Housing parts in a first detent position, so holding connected to the surrounding housing clamping sleeves open the sleeve contacts, so that the
Kontaktstifte eines Gegensteckverbinders, der als Aggregateanschlusses bezeichnet ist, nahezu kraftfrei mit den Hülsenkontakten verbunden werden können. Das Anfügen des Aggregateanschlusses löst die Fixierung der Rastverbindung zwischen den Gehäuseteilen des Steckhülsengehäuses und bringt die diese relativ zueinander in eine zweite Raststellung, in der die Spannhülsen Kontaktlamellen der Hülsenkontakte an die Kontaktstifte des Aggregateanschlusses anpressen. Contact pins of a mating connector, which is referred to as aggregate connection, can be connected to the sleeve contacts almost force-free. The attachment of the unit connection solves the fixation of the locking connection between the housing parts of the receptacle housing and brings them relative to each other in a second detent position in which the Clamping sleeves Press the contact lamellae of the sleeve contacts onto the contact pins of the unit connection.
Der Verrastungsmechanismus zwischen dem Umgehäuse und dem The latching mechanism between the housing and the
Fixiergehäuse bewirkt, dass die Kontaktstifte des Aggregateanschlusses nahezu kraftfrei in die Hülsenkontakte eingeschoben werden können, und eine Kontaktkraft zwischen den Kontaktlamellen der Hülsenkontakte und den Kontaktstiften erst in der letzten Phase des Zusammenfügens der Fixiergehäuse causes the contact pins of the unit connection can be inserted almost force-free in the sleeve contacts, and a contact force between the contact blades of the sleeve contacts and the contact pins until the last phase of assembling the
Steckverbinderteile erzeugt wird. Damit sich mechanische Einwirkungen auf das Umgehäuse oder den Aggregateanschluss nicht auf die miteinander verbundenen elektrischen Kontaktelemente übertragen oder die Verbindungen der Kontaktelemente sogar auftrennen können, ist an einer äußeren Wand des Umgehäuses eine federnde Rastwippe angeformt. Beim Anfügen an den Aggregateanschluss rastet ein Federarm der Rastwippe über eine Rastnase am Aggregateanschluss und verbindet damit beide Steckverbinderteile formschlüssig miteinander. Das Öffnen dieser Rastverbindung zum Connector parts is generated. So that mechanical effects on the surrounding housing or the unit connection can not be transferred to the interconnected electrical contact elements or even disconnect the connections of the contact elements, a resilient detent rocker is formed on an outer wall of the surrounding housing. When attached to the unit connection, a spring arm of the locking rocker engages via a latching lug on the unit connection and thus connects the two connector parts with one another in a form-fitting manner. The opening of this locking connection to
bedarfsweisen Trennen der beiden Steckverbinderteile kann durch As needed, the two connector parts can be disconnected
Druckausübung auf den freien Federarm der Rastwippe bewirkt werden. Bei diesem vorbekannten Nullkraftsteckverbinder erfolgen das Verschieben der Spannhülsen an den Hülsenkontakten und das Verrasten von Rastwippe und Rastnase am Umgehäuse und am Aggregateanschluss mechanisch unabhängig voneinander. Es besteht daher keine Gewähr dafür, dass beim Verschieben der Spannhülsen auch die Rastverbindung zwischen Umgehäuse und Aggregateanschluss hergestellt wird oder umgekehrt, dass bei Pressure to be exerted on the free spring arm of the locking rocker. In this known zero-force connector, the displacement of the clamping sleeves on the sleeve contacts and the locking of locking rocker and locking lug on the housing and the unit connection mechanically independent of each other. Therefore, there is no guarantee that when moving the clamping sleeves and the locking connection between the housing and the unit connection is made or vice versa, that at
miteinander verrastetem Umgehäuse und Aggregateanschluss auch die Spannhülsen an den Hülsenkontakten bis in ihre Endstellung verschoben sind. locked housing and aggregate connection and the clamping sleeves are moved to the sleeve contacts to their final position.
Es stellte sich daher die Aufgabe, einen elektrischen Nullkraftsteckverbinder zu schaffen, der ein vollständiges elektrisches und mechanisches Verbinden der Steckverbinderteile sicherstellt. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass am Steckhülsengehäuse ein Riegel angeordnet ist, der nach dem It was therefore an object to provide a zero-force electrical connector that ensures complete electrical and mechanical connection of the connector parts. This object is achieved in that the receptacle housing a latch is arranged, which after the
Zusammenfügen von Steckhülsengehäuse und Aggregateanschluss gegen das Steckhülsengehäuse verschiebbar ist und der nach dem Verschieben die Rastverbindung von Rasthaken und Rastnase arretiert, und dass der Riegel mit einem durch mindestens eine Ausnehmung des Dichtelements geführten und mit den Spannhülsen gekoppelten Schieber verbunden ist und den Schieber bei einer Verschiebung mitbewegt. Mating of socket housing and unit connection is displaceable against the socket housing and locks the locking connection of latching hook and latching lug after moving, and that the latch is connected to a guided by at least one recess of the sealing element and coupled to the clamping sleeves slide and the slide during a shift moved.
Bei dem erfindungsgemäßen Nullkraftsteckverbinder erfolgt somit das Verrasten von Steckhülsengehäuse und Aggregateanschluss und das Verschieben der Spannhülsen mittels mechanisch gekoppelter Elemente, so dass beide mechanischen Abläufe nur gemeinsam erfolgen können. Die von außen gut erkennbare Schiebestellung des Riegels zeigt dem Anwender zugleich auch die Verschiebeposition der Spannhülsen an. In the case of the zero-force plug connector according to the invention, the latching of plug-in socket housing and unit connection and the displacement of the clamping sleeves by means of mechanically coupled elements thus take place, so that both mechanical processes can only take place together. The well-visible from the outside sliding position of the bolt also shows the user at the same time the displacement position of the clamping sleeves.
Hierbei stellte sich allerdings das Problem, auf die Spannhülsen mechanisch zuzugreifen, die im Inneren einer Kammer angeordnet sind, die durch das mit dem Aggregateanschluss verbundene Steckverbindergehäuse ausgebildet wird, und die durch ein Dichtelement gegen Feuchtigkeit geschützt ist. Ein Verzicht auf das Dichtelement hätte zu einer mangelhaften Abdichtung der Steckverbinderanordnung geführt. Dieses Problem wird durch einen Schieber gelöst der durch mindestens eine Ausnehmung des Dichtelements hindurchgeführt ist. Hierdurch kann das Dichtelement an seinem Platz verbleiben und zugleich die Verbindung von Schieber und Riegels abdichten. Vorteilhaft ist es, dass der Riegel erst nach dem Zusammenfügen von Steckhülsengehäuse und Aggregateanschluss gegen das Steckhülsengehäuse verschiebbar ist. Beim Anfügen des Here, however, there was the problem of mechanically accessing the clamping sleeves, which are arranged in the interior of a chamber which is formed by the connector housing connected to the power connector, and which is protected by a sealing element against moisture. A waiver of the sealing element would have led to a poor seal of the connector assembly. This problem is solved by a slider which is passed through at least one recess of the sealing element. In this way, the sealing element can remain in place and at the same time seal the connection between slide and bolt. It is advantageous that the bolt only after the assembly of receptacle housing and unit connection against the Socket housing is displaceable. When attaching the
Steckhülsengehäuses befindet sich dadurch der Riegel in der korrekten Montageposition, was zusätzlichen Montageaufwand vermeidet. Dies kann auf vorteilhafte Weise dadurch realisiert sein, dass der Riegel einen angeformten Vorsprung aufweist, der zunächst durch den Rasthaken des Socket housing is characterized by the bolt in the correct mounting position, which avoids additional installation effort. This can be realized in an advantageous manner by the fact that the bolt has a molded-on projection, which is initially formed by the latching hook of the
Steckhülsengehäuses blockiert ist und durch das Verrasten des Rasthakens an der Rastnase des Umgehäuses freigegeben wird.  Plug sleeve housing is blocked and is released by the latching of the latching hook on the locking lug of the surrounding housing.

In der Figur 1 sind zwei miteinander verbindbare Steckverbinderteile 1 , 6 eines erfindungsgemäßen Nullkraftsteckverbinders im noch unverbundenen Zustand dargestellt. Die Steckverbinderteile 1 , 6 werden hier speziell auch als In FIG. 1, two connector parts 1, 6 which can be connected to each other of a zero-force connector according to the invention are shown in the still unconnected state. The connector parts 1, 6 are here specifically as
Steckhülsengehäuse 1 und Aggregateanschluss 6 bezeichnet. Das Steckhülsengehäuse 1 besteht aus einem äußeren Umgehäuse 15 und einem inneren Kontaktträger 16, die entweder einstückig oder als miteinander verbundene Einzelteile ausgeführt sein können und die besonders deutlich in der Figur 5 erkennbar sind. Der Kontaktträger 16 besitzt mehrere röhrenartige Aufnahmen 25, in die aus Metall geformte Hülsenkontakte 2 eingesetzt sind. Einen Hülsenkontakt 2, wie er bereits in der DE 10 2005 040 952 A1 beschrieben ist, zeigt als Einzelteil die Figur 7 in zwei Ansichten a) und b). Der Hülsenkontakt 2 besteht aus einem metallenen Grundkörper 4, der mit einer elektrischen Leitung 22 verbunden ist. Die Leitung 22 weist einen elektrischen Leiter 17 auf, der mittels einer Crimpverbindung 20 elektrisch und mechanisch mit dem Grundkörper 4 verbunden ist. Ein die elektrische Leitung 22 Socket housing 1 and unit connection 6 referred to. The receptacle housing 1 consists of an outer housing 15 and an inner contact carrier 16, either in one piece or as one another Connected items can be executed and which are particularly clearly visible in the figure 5. The contact carrier 16 has a plurality of tube-like receptacles 25 are inserted into the metal-shaped sleeve contacts 2. A sleeve contact 2, as already described in DE 10 2005 040 952 A1, shows as an individual part the figure 7 in two views a) and b). The sleeve contact 2 consists of a metal base body 4, which is connected to an electrical line 22. The line 22 has an electrical conductor 17, which is electrically and mechanically connected to the base body 4 by means of a crimp connection 20. An electrical line 22
umgebendes Dichtgummi 18 ist im Übergangsbereich von der Leitung 22 zum Grundkörper 4 über zwei Biegelaschen 19 am Grundkörper 4 befestigt. Für eine bessere Übersichtlichkeit wurde auf die Darstellung elektrischer Leitungen in den übrigen Figuren verzichtet. surrounding sealing rubber 18 is fixed in the transition region from the line 22 to the base body 4 via two bending tabs 19 on the base body 4. For better clarity, the illustration of electrical lines in the other figures was omitted.
Den freien Endabschnitt des Grundkörpers 4 bilden zwei einstückig an den Grundkörper 4 angeformte, nebeneinander liegende Kontaktlamellen 3, in deren Zwischenraum 21 ein in dieser Figur nicht dargestellter flacher The free end portion of the base body 4 form two integrally formed on the base body 4, adjacent contact blades 3, in the space 21, a flat in this figure, not shown
Steckerstift einfügbar ist. Die Enden der Kontaktlamellen 3 sind jeweils nach außen umgebogen. Am Grundkörper 4 federnd befestigt ist eine den Plug pin is inserted. The ends of the contact blades 3 are each bent to the outside. Fastened to the base body 4 is a spring
Grundkörperquerschnitt teilweise umgreifende Spannhülse 5. Die Spannhülse 5 besitzt in Querrichtung mehrere schlitzförmige Durchbrüche 23, welche eine flache Federkennlinie bewirken. Des Weiteren ist die Spannhülse 5 entlang des Grundkörpers 4 verschieblich angeordnet. Befindet sich die Spannhülse 5 im Bereich der Kontaktlamellen 3, wie in der Ansicht b) gezeigt, so drückt die Spannhülse 5 die Kontaktlamellen 3 aufeinander zu. Ist die Spannhülse 5 dagegen, entsprechend der Ansicht a), entfernt von den Kontaktlamellen 3 angeordnet, so wirken von der Spannhülse 5 keine Druckkräfte auf die  The clamping sleeve 5 has in the transverse direction a plurality of slot-shaped openings 23, which cause a flat spring characteristic. Furthermore, the clamping sleeve 5 is arranged displaceably along the base body 4. The clamping sleeve 5 is located in the region of the contact blades 3, as shown in the view b), so the clamping sleeve 5 presses the contact blades 3 towards each other. If the clamping sleeve 5, however, arranged according to the view a), away from the contact blades 3, act from the clamping sleeve 5 no pressure forces on the
Kontaktlamellen 3. Die letztgenannte Anordnung der Spannhülse 5 auf dem Grundkörper 4 ermöglicht es daher, einen Steckerstift nahezu kräftefrei in den Zwischenraum 21 zwischen den Kontaktlamellen 3 einzufügen. Gemäß der Figur 1 gehört zum Steckhülsengehäuse 1 ein am Umgehäuse 15 verschiebbar angeordneter Riegel 1 1 . Wie die Figuren 4 und 5 verdeutlichen, weist der Riegel 1 1 zwei Arme 27 auf, die jeweils mit einem Stift 14 eines Schiebers 13 verbunden sind. Die Stifte 14 sind durch Ausnehmungen 12 in einem Dichtelement 10 hindurchgeführt, welches den Kontaktträger 16 umschließt und bei miteinander verbundenen Steckverbinderteilen 1 , 6 den Kontaktträger 16 gegen den Aggregateanschluss 6 abdichtet. Die Durchführung eines Stifts 14 durch eine Ausnehmung 12 im Dichtelement 10 ist in der Figur 6 in einer Vergrößerung eines Ausschnitts A aus der Figur 5 dargestellt. Der Stift 14 kann entlang der Ausnehmung 12 verschoben werden, wobei das gummielastische Dichtelement 10 den Stift 14 stets Contact lamellae 3. The latter arrangement of the clamping sleeve 5 on the base body 4 therefore makes it possible to insert a pin almost free of force in the gap 21 between the contact blades 3. According to FIG. 1, the receptacle housing 1 includes a latch 1 1 which is displaceably arranged on the surrounding housing 15. As FIGS. 4 and 5 make clear, the latch 11 has two arms 27 which are each connected to a pin 14 of a slider 13. The pins 14 are passed through recesses 12 in a sealing element 10, which encloses the contact carrier 16 and seals the contact carrier 16 against the aggregate connection 6 when the connector parts 1, 6 are connected to one another. The passage of a pin 14 through a recess 12 in the sealing element 10 is shown in Figure 6 in an enlargement of a section A of Figure 5. The pin 14 can be moved along the recess 12, wherein the rubber-elastic sealing element 10, the pin 14 always
feuchtigkeitsdicht umschließt. Für die Realisierung des hier beispielhaft zylinderförmig dargestellten Stifts 14 kann selbstverständlich auch eine andere, beispielsweise ovale oder mehreckige Querschnittskontur vorgesehen werden. encloses moisture-proof. Of course, another, for example oval or polygonal cross-sectional contour can be provided for the realization of the pin 14 shown here by way of example as a cylinder.
In der Figur 5 und besonders deutlich in der Figur 4 ist als ein weiterer In the figure 5 and particularly clearly in the figure 4 is as a further
Bestandteil des Schiebers 13 ein Rahmen 28 erkennbar, welcher mit beiden Stiften 14 verbunden ist. Anformungen 30 am Rahmens 28 greifen in die schlitzförmigen Durchbrüche 23, abgebildet in der Figur 7, der Spannhülsen 5 ein, wodurch eine vertikale Bewegung des Schiebers 13 die Spannhülsen 5 gegen den Grundkörper 4 der Hülsenkontakte 2 verschiebt. Part of the slider 13, a frame 28 recognizable, which is connected to both pins 14. Anformungen 30 on the frame 28 engage in the slot-shaped apertures 23, shown in Figure 7, the clamping sleeves 5, whereby a vertical movement of the slider 13, the clamping sleeves 5 against the base body 4 of the sleeve contacts 2 moves.
Das Verbinden des Steckhülsengehäuses 1 mit dem Aggregateanschluss 6 erfolgt wie folgt. Wie bereits erwähnt zeigt die Figur 1 die beiden The connection of the receptacle housing 1 to the unit connection 6 takes place as follows. As already mentioned, FIG. 1 shows the two
Steckverbinderteile 1 , 6 im noch unverbundenen Zustand. Der Riegel 1 1 am Steckhülsengehäuse 1 befindet sich in seiner Anfangsposition, da der federnd am Steckhülsengehäuse 1 angeformte Rasthaken 8 ein Hindernis für den am Riegel 1 1 angeformten Vorsprung 26 dargestellt und daher eine Verschiebung des Riegels 1 1 gegen das Steckhülsengehäuse 1 blockiert. Da die Spannhülsen 5 über den Schieber 13 mechanisch mit dem Riegel 1 1 gekoppelt sind, befinden sich auch die Spannhülsen 5 der Hülsenkontakte 2 in ihrer Grundstellung, in welcher die Steckerstifte 7 des Aggregateanschlusses 6 in die Hülsenkontakte 2 einschiebbar sind. Connector parts 1, 6 in the still unconnected state. The latch 1 1 on the receptacle housing 1 is in its initial position, since the resiliently molded to the receptacle housing 1 latching hooks 8 an obstacle for the integrally formed on the latch 1 1 projection 26 and therefore blocks a displacement of the bolt 1 1 against the receptacle housing 1. Because the Clamping sleeves 5 are mechanically coupled via the slide 13 to the latch 1 1, are also the clamping sleeves 5 of the sleeve contacts 2 in their normal position in which the connector pins 7 of the unit connection 6 in the sleeve contacts 2 are inserted.
Hierdurch kann das Steckhülsengehäuse 1 an den Aggregateanschluss 6 angefügt werden, wobei die Steckerstifte 7 in zugeordnete Hülsenkontakte 2 einfahren. Der hierdurch erreichte Montagezustand ist in der Figur 2 in einer Schnittansicht dargestellt. Erkennbar ist, dass der Rasthaken 8 des In this way, the receptacle housing 1 can be added to the unit connection 6, wherein the plug pins 7 retract into associated sleeve contacts 2. The assembly state achieved as a result is shown in FIG. 2 in a sectional view. It can be seen that the latch hook 8 of the
Steckhülsengehäuses 1 nun hinter der Rastnase 9 des Aggregateanschlusses 6 verrastet ist. Die Rastnase 9 liegt an dem Vorsprung 26 des Riegels 1 1 an, wodurch der Vorsprung 26 bei einer Druckeinwirkung auf das Socket housing 1 is now latched behind the locking lug 9 of the unit connection 6. The detent 9 is applied to the projection 26 of the bolt 1 1, whereby the projection 26 at a pressure on the
Betätigungselement 29 des Riegels 1 1 über die Rastnase 9 gleitet und der Riegel 1 1 gegen das Steckhülsengehäuse 1 verschoben wird. Actuator 29 of the bolt 1 1 slides over the locking lug 9 and the bolt 1 1 is moved against the socket housing 1.
Bei dieser Verschiebebewegung nimmt der Riegel 1 1 den mechanisch angekoppelten Schieber 13 mit. Die beiden durch das Dichtelement 10 geführten Stifte 14 sind an ihrer Unterseite einstückig mit dem ovalen oder rechteckförmigen Rahmen 28 verbunden, welcher eine der Zahl der In this sliding movement of the latch takes 1 1 the mechanically coupled slider 13. The two guided by the sealing element 10 pins 14 are integrally connected at its bottom with the oval or rectangular frame 28, which one of the number
Hülsenkontakte 2 entsprechende Anzahl von Anformungen 30 aufweist, welche mechanisch an den Spannhülsen 5 angreifen. Zusätzlich ist ein Sekundärriegel 24 vorgesehen, welcher mit beiden Stiften 14 verbunden ist und der an der Oberseite der Spannhülsen 5 anliegt. Die Bewegung des Schiebers 13 verschiebt so die Spannhülsen 5 gegen die Hülsenkontakte 2, wodurch sich die Kontaktlamellen 3 der Hülsenkontakte 2 eng um die Sleeve contacts 2 corresponding number of projections 30 which mechanically engage the clamping sleeves 5. In addition, a secondary bar 24 is provided, which is connected to both pins 14 and which bears against the upper side of the clamping sleeves 5. The movement of the slider 13 thus shifts the clamping sleeves 5 against the sleeve contacts 2, whereby the contact blades 3 of the sleeve contacts 2 closely around the
Steckerstifte 7 des Aggregateanschlusses 6 schließen. Close plug pins 7 of the unit connection 6.
Der Riegel 1 1 , der Schieber 13 und die Spannhülsen 5 erreichen schließlich ihre Endpositionen, die in der Darstellung der Figur 3 ersichtlich sind. Der Riegel 1 1 blockiert in seiner Endposition die Beweglichkeit von Rasthaken 8 und Rastnase 9 relativ zueinander, wodurch das Steckhülsengehäuse 1 und der Aggregateanschluss 6 nun formschlüssig miteinander verbunden und arretiert sind. Das Arretieren der Steckverbinderteile 1 , 6 gegeneinander und das Aktivieren der Hülsenkontakte 2 durch die Verschiebung der Spannhülsen 5 wird somit gleichzeitig und in einem einzigen Montageschritt durch die Verschiebung des Riegels 1 1 erreicht. The bolt 1 1, the slider 13 and the clamping sleeves 5 finally reach their end positions, which can be seen in the illustration of Figure 3. The latch 1 1 blocked in its final position, the mobility of latching hook 8 and detent 9 relative to each other, whereby the receptacle housing 1 and the aggregate connection 6 is now positively connected to each other and locked. The locking of the connector parts 1, 6 against each other and the activation of the sleeve contacts 2 by the displacement of the clamping sleeves 5 is thus achieved simultaneously and in a single assembly step by the displacement of the bolt 1 1.
Das Trennen der Steckverbinderteile 1 , 6 erfolgt in genau umgekehrter Abfolge des Verbindungsvorgangs. Um die beiden Steckverbinderteile 1 , 6 The separation of the connector parts 1, 6 takes place in exactly the reverse sequence of the connection process. To the two connector parts 1, 6
voneinander zu lösen, ist zunächst der Riegel 1 1 zu ziehen, dass heißt in die in der Figur 2 dargestellte Position zu bringen. Danach kann das to solve each other, is first to pull the latch 1 1, that is to bring in the position shown in Figure 2. After that, that can
Steckhülsengehäuse 1 vom Aggregateanschluss 6 getrennt werden. Socket housing 1 are separated from the unit connection 6.
