Description

Die Erfindung betrifft einen elektrischen Nullkraftsteckverbinder mit einem Kontaktträger, welcher Aufnahmen für mehrere Hülsenkontakte aufweist, wobei die Hülsenkontakte jeweils einen Kontaktlamellen ausbildenden Grundkörper und eine gegenüber dem Grundkörper verschiebliche Spannhülse aufweisen, und mit einem Aggregateanschluß, der die Hülsenkontakte kontaktierende Kontaktstifte aufweist, und mit einem Gehäuseteil, das in wenigstens zwei Stellungen an dem Kontaktträger positionierbar ist, wobei der Aggregateanschluß beim Zusammenfügen mit dem Kontaktträger eine Verschiebesicherung zwischen dem Gehäuseteil und dem Kontaktträger löst, und wobei durch eine Verschiebung des Gehäuseteils gegen den Kontaktträger zugleich die Spannhülsen entlang des Grundkörpers der Hülsenkontakte verschoben werden und die Spannhülsen die Kontaktlamellen an die Kontaktstifte des Aggregateanschlusses anpressen, wobei der Kontaktträger einen zweiarmigen Hebel lagert und wobei die Verschiebung des Gehäuseteils einen ersten Hebelarm des Hebels formschlüssig mit dem Aggregateanschluß verbindet.The invention relates to an electrical zero-force connector having a contact carrier, which has receptacles for a plurality of sleeve contacts, the sleeve contacts each having a contact blade forming body and a sliding relative to the base body clamping sleeve, and having an aggregate terminal, the sleeve contacts contacting contact pins, and having a housing part which is positionable in at least two positions on the contact carrier, wherein the aggregate terminal when mating with the contact carrier solves a displacement safety between the housing part and the contact carrier, and wherein at the same time the clamping sleeves are moved along the base body of the sleeve contacts by a displacement of the housing part against the contact carrier and the clamping sleeves press the contact blades to the contact pins of the unit connection, wherein the contact carrier supports a two-armed lever and wherein the Versc pushing the housing part connects a first lever arm of the lever form-fitting manner with the unit connection.

Ein derartiger elektrischer Nullkraftsteckverbinder ist aus der deutschen Offenlegungsschrift DE 10 2005 040 952 A1 bekannt. Dieser Nullkraftsteckverbinder weist zwei Gehäuseteile auf, in diesem Dokument als Umgehäuse und Fixiergehäuse bezeichnet, die zueinander zwei Raststellungen einnehmen können. Befinden sich die Gehäuseteile in einer ersten Raststellung relativ zueinander, so halten die mit dem Umgehäuse verbundenen Spannhülsen die Hülsenkontakte geöffnet, so dass die Kontaktstifte eines Gegensteckverbinders, der als Aggregateanschlusses bezeichnet ist, kraftfrei mit den Hülsenkontakten verbunden werden können. Das Anfügen des Aggregateanschlusses löst die Fixierung der Rastverbindung zwischen den Gehäuseteilen und bringt die Gehäuseteile zueinander in eine zweite Raststellung, in der die Spannhülsen Kontaktlamellen der Hülsenkontakte an die Kontaktstifte des Aggregateanschlusses anpressen.Such a zero-force electrical connector is known from the German patent application DE 10 2005 040 952 A1 known. This zero-force connector has two housing parts, referred to in this document as a housing and fixing housing, which can assume two detent positions to each other. If the housing parts are in a first detent position relative to one another, then the clamping sleeves connected to the surrounding housing keep the sleeve contacts open, so that the contact pins of a mating connector, which is referred to as an aggregate connection, can be connected to the sleeve contacts without force. The attachment of the unit connection solves the fixation of the locking connection between the housing parts and brings the housing parts to each other in a second detent position in which press the clamping sleeves contact blades of the sleeve contacts to the contact pins of the unit connection.

Dieser Verrastungsmechanismus bewirkt, dass die Kontaktelemente kraftfrei eingesetzt werden können, wobei die Kontaktkraft zwischen den Kontaktlamellen der Hülsenkontakte und den Kontaktstiften erst in der letzten Phase des Zusammenfügens der Steckverbinderteile erzeugt wird. Damit sich mechanische Belastungen nicht auf die miteinander verbundenen 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 an einer Rastnase am Aggregateanschluß ein und verbindet damit beide Steckverbinderteile formschlüssig miteinander. Das Öffnen dieser Rastverbindung zum bedarfsweisen Trennen der beiden Steckverbinderteile kann durch Druckausübung auf den freien Federarm der Rastwippe bewirkt werden.This locking mechanism causes the contact elements can be used force-free, wherein the contact force between the contact blades of the sleeve contacts and the contact pins is generated only in the final phase of assembly of the connector parts. So that mechanical loads can not be transferred to the interconnected 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 attaching to the unit connection, a spring arm of the locking rocker engages a latching lug on the unit connection and thus connects the two connector parts with each other in a form-fitting manner. The opening of this latching connection to the need-based separation of the two connector parts can be effected by applying pressure to the free spring arm of the locking rocker.

Beim Anfügen des vorbekannten Steckverbinderteils an den Aggregateanschluß entstehen durch das Verrasten von Umgehäuse und Fixiergehäuse einerseits und durch das Verrasten der Rastwippe vom Umgehäuse am Aggregateanschluß andererseits zwei akustisch oder sogar haptisch wahrnehmbare Rastgeräusche, die bei korrekter Steckung in kurzem zeitlichen Abstand aufeinander folgen.When attaching the previously known connector part to the unit connection caused by the latching of the housing and fixing housing on the one hand and by the locking of the locking rocker from the housing on the aggregate connection on the other two acoustically or even haptic perceptible locking noises that follow each other at the correct plug in a short time interval.

Da bei konventionellen Steckverbindern im Regelfall nur ein Rastgeräusch entsteht, kann eine die Steckverbindung zusammenfügende Person fälschlicherweise davon ausgehen, dass die Steckverbindung korrekt montiert worden ist, wenn ein Rastgeräusch erkennbar war. Besteht keine formschlüssige mechanische Arretierung zwischen den Steckverbinderteilen, so kann dies bei mechanischen Einwirkungen auf die Steckverbindung zu Fehlfunktionen und besonders bei sicherheitskritischen Anwendungen sogar zu Gefährdungen führen.Since in conventional connectors usually only a detent noise is created, a person assembling the connector may erroneously assume that the connector has been mounted correctly when a click sound was detected. If there is no positive mechanical locking between the connector parts, this may be due to mechanical effects on the connector Malfunctions and even in safety-critical applications even lead to hazards.

Es stellte sich die Aufgabe, einen Steckverbinder zu schaffen, dessen Aufbau diese Fehlermöglichkeiten ausschließt.The object was to create a connector whose structure excludes these possibilities of error.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Verschiebung des Gehäuseteils zunächst den Abschnitt des ersten Hebelarms verschiebt und dadurch in dem zweiten Hebelarm der an dem Gehäuseteil anliegt, eine Federspannung aufbaut, und dass der zweite Hebelarm mit einem Rastgeräusch am oder hinter dem Gehäuseteil einrastet wenn das Gehäuseteil eine Endstellung erreicht.This object is achieved in that the displacement of the housing part initially moves the portion of the first lever arm and thereby rests in the second lever arm on the housing part, a spring tension builds up, and that the second lever arm engages with a locking noise on or behind the housing part if the housing part reaches an end position.

Die Erfindung zeichnet sich dadurch aus, dass während des Steckvorgangs das Aufbringen der Kontaktnormalkraft und die Fixierung der Steckverbinderteile aneinander nacheinander erfolgen, wobei eine akustisch oder haptisch wahrnehmbare Rückmeldung als Signal für die ordnungsgemäße Montage erst nach Abschluss des zweiten Vorgangs erfolgt.The invention is characterized in that the contact normal force and the fixation of the connector parts are successively applied during the plugging operation, wherein an acoustically or haptically perceivable feedback as a signal for the proper assembly takes place only after completion of the second process.

Die Figur 1 zeigt einen Kontaktträger 1, der mehrere Hülsenkontakte 2 aufnehmen und in Aufnahmekammern 20 haltern kann. Die vorderenThe FIG. 1 shows a contact carrier 1, which can receive a plurality of sleeve contacts 2 and hold in receiving chambers 20. The front

Abschnitte der Hülsenkontakte 2 erstrecken sich dabei bis an ein an den Kontaktträger 1 anfügbares Abdeckelement 15.Sections of the sleeve contacts 2 extend as far as an attachable to the contact carrier 1 cover 15th

Die Hülsenkontakte 2 bestehen jeweils aus einem Grundkörper 16, der über eine Crimpverbindung 17 mit einer elektrischen Anschlussleitung 18 verbunden ist. Die Anschlussleitung 18 ist jeweils mit einem Dichtgummi 19 umgeben, die, nach Einsetzen des Hülsenkontakts 2 in eine Aufnahmekammer 20 des Kontaktträgers 1, die jeweilige Aufnahmekammer 20 gegen das Eindringen von Feuchtigkeit abdichtet.The sleeve contacts 2 each consist of a base body 16, which is connected via a crimp 17 to an electrical connection line 18. The connecting line 18 is in each case surrounded by a sealing rubber 19 which, after insertion of the sleeve contact 2 into a receiving chamber 20 of the contact carrier 1, seals the respective receiving chamber 20 against the ingress of moisture.

Jeder Hülsenkontakt 2 weist eine am Grundkörper 16 verschiebbar angeordnete Spannhülse 21 auf, die in einer Verschiebeposition Kontaktlamellen aufeinander zu bewegt. Sind in den Grundkörper 16 Kontaktstifte eines, in der Figur 1 nicht dargestellten, Aggregateanschlusses eingefügt, so werden die Kontaktlamellen in dieser Verschiebeposition gegen die Kontaktstifte gepresst, wodurch eine sichere elektrische Kontaktierung hergestellt ist. Befindet sich die Spannhülse 21 dagegen in der entgegengesetzten Verschiebeposition, so wirkt keine Kontaktkraft auf die Kontaktstifte, so dass diese kraftfrei in die Grundkörper 16 der Hülsenkontakte 2 eingeschoben oder aus diesen entfernt werden können.Each sleeve contact 2 has a clamping sleeve 21, which is displaceably arranged on the base body 16 and which moves contact blades toward one another in a displacement position. Are in the main body 16 pins one, in the FIG. 1 not shown, inserted aggregate connection, the contact blades are pressed in this displacement position against the contact pins, creating a secure electrical contact is made. The clamping sleeve 21, however, is in the opposite displacement position, no contact force acts on the contact pins, so that they can be pushed without force into the base body 16 of the sleeve contacts 2 or removed therefrom.

Bei einem montierten Steckverbinderteil sind die Spannhülsen 21 mit einem Gehäuseteil 5 verbunden und werden durch eine Verschiebung des Gehäuseteil 5 gegen den Kontaktträger 1 mitbewegt und betätigt. Das Gehäuseteil 5 besitzt die Form einer Hülse, die den Kontaktträger 1 umgibt und die am Kontaktträger 1 in Richtung dessen Längsachse verschiebbar ist.In a mounted connector part, the clamping sleeves 21 are connected to a housing part 5 and are moved and actuated by a displacement of the housing part 5 against the contact carrier 1. The housing part 5 has the shape of a sleeve which surrounds the contact carrier 1 and which is displaceable on the contact carrier 1 in the direction of its longitudinal axis.

Innerhalb des Kontaktträgers 1 ist ein Hebel 7 an einer Lagerstelle 22 verschwenkbar angeordnet. Der Hebel 7 ist als ein Kunststoffstreifen ausgeführt, der an einem Endabschnitt einen angeformten Rasthaken 13 und am gegenüberliegenden Endabschnitt ein angeformtes Rastelement 24 aufweist. In einem mittleren Abschnitt besitzt der Hebel 7 senkrecht zur seiner Längsachse angeformte Achsstummel 14, die in eine Aufnahme an der Lagerstelle 22 am Kontaktträger 1 einsetzbar sind. Hierdurch bildet der Hebel 7 einen im physikalischen Sinne zweiarmigen Hebel aus. Ein gegen das Gehäuseteil 5 verschiebbarer Riegel 11 ermöglicht in wenigstens einer Hebelstellung bei korrekt verrastetem Gehäuse eine Arretierung des Hebels 7.Within the contact carrier 1, a lever 7 is pivotally mounted at a bearing point 22. The lever 7 is as a plastic strip executed, which has an integrally formed latching hook 13 at one end portion and an integrally formed latching element 24 at the opposite end portion. In a central portion of the lever 7 has perpendicular to its longitudinal axis integrally formed stub axle 14, which are insertable into a receptacle on the bearing point 22 on the contact carrier 1. As a result, the lever 7 forms a two-armed lever in the physical sense. A displaceable against the housing part 5 bolt 11 allows in at least one lever position with correctly latched housing a locking of the lever. 7

Die Figuren 2 bis 5 verdeutlichen in jeweils einer Querschnittsansicht verschiedene Montagephasen beim Anfügen des Steckverbinderteils an einen mehrere Kontaktstifte 4 aufweisenden Aggregateanschluß 3.The FIGS. 2 to 5 illustrate in each case a cross-sectional view of various mounting phases when attaching the connector part to a plurality of pins 4 having aggregate connection. 3

Die Figur 2 zeigt den Beginn des Steckvorgangs, bei dem die Kontaktstifte 4 des Aggregateanschlusses 3 erst teilweise in die Hülsenkontakte 2 eingeschoben sind. Erkennbar ist ein Zwischenraum 25 zwischen der Unterseite des Abdeckelements 15 und der Grundfläche des Aggregateanschlusses 3, woran ersichtlich ist, dass die Steckverbinderteile noch nicht vollständig verbunden sind.The FIG. 2 shows the beginning of the plug-in process, in which the contact pins 4 of the unit connection 3 are only partially inserted into the sleeve contacts 2. Visible is a gap 25 between the underside of the cover 15 and the base of the unit connection 3, as can be seen that the connector parts are not yet fully connected.

Das Einfügen der Kontaktstifte 4 in die Hülsenkontakte 2 erfolgt kraftfrei, da sich das mit den Spannhülsen verbundene Gehäuseteil 5 relativ zum Kontaktträger 1 in einer Position befindet, in der die Spannhülsen die Hülsenkontakte 2 zum Einschieben der Kontaktstifte 4 offen halten. Diese Positionierung wird durch eine Verschiebesicherung 6 festgelegt, welche in dieser Montagephase eine Verschiebung des Gehäuseteils 5 gegen den Kontaktträger 1 verhindert.The insertion of the contact pins 4 in the sleeve contacts 2 is force-free, since the housing part 5 connected to the clamping sleeves is relative to the contact carrier 1 in a position in which the clamping sleeves hold the sleeve contacts 2 for insertion of the contact pins 4 open. This positioning is determined by a displacement lock 6, which prevents a displacement of the housing part 5 against the contact carrier 1 in this assembly phase.

Durch einen Punkt angedeutet ist die Lage der Drehachse 29 des zweiarmigen Hebels 7, entsprechend einem Schnitt durch eine gedachten Längsachse durch die in der Figur 1 dargestellten beiden Achsstummel 14.Indicated by a point is the position of the axis of rotation 29 of the two-armed lever 7, corresponding to a section through an imaginary longitudinal axis by in the FIG. 1 shown two axle stub 14th

Der am Hebel 7 angeformte Rasthaken 13 befindet sich in dieser Fügephase etwa auf der Höhe eines am Aggregateanschluß 3 angeformten ersten Vorsprungs 12. Dem ersten Vorsprung 12 gegenüberliegend weist der Aggregateanschluß 3 einen angeformten zweiten Vorsprung 23 auf, der in dieser Fügephase in eine Einbuchtung eines abgewinkelten Wandabschnitts 26 des Gehäuseteils 5 hineinragt, welcher einen Teil der Verschiebesicherung 6 ausbildet.The integrally formed on the lever 7 locking hook 13 is located in this joining phase approximately at the level of an integrally formed on the unit connection 3 first projection 12. The first projection 12 opposite the aggregate terminal 3 has a molded-on second projection 23 which in this joining phase in an indentation of an angled Wall portion 26 of the housing part 5 protrudes, which forms a part of the anti-displacement device 6.

In der nächsten Fügephase, welche die Figur 3 darstellt, hat die Unterseite des Abdeckelements 15 die Grundfläche des Aggregateanschlusses 3 erreicht und das Einschieben der Kontaktstifte 4 in die Hülsenkontakte 2 ist abgeschlossen.In the next joining phase, which the FIG. 3 represents, the bottom of the cover 15 has reached the base of the unit port 3 and the insertion of the contact pins 4 in the sleeve contacts 2 is completed.

Der Rasthaken 13 des Hebels 7 liegt nun unterhalb des ersten Vorsprungs 12 des Aggregateanschlusses 3, rastet jedoch nicht an diesem ein, da keine Betätigungskraft verschiebend auf einen der Hebelarme (8, 9) des Hebels 7 einwirkt und der Hebel 7 auch nicht federnd vorgespannt ist. Zugleich trifft der abgewinkelten Wandabschnitt 26 auf den zweiten Vorsprung 23 des Aggregateanschlusses 3, wodurch die die Verschiebesicherung 6, d. h. die formschlüssige Verbindung zwischen dem Gehäuseteil 5 und dem Kontaktträger 1, gelöst wird. Hierdurch ist nun das Gehäuseteil 5 gegen den Kontaktträger 1 verschiebbar.
Beim Verschieben des Gehäuseteils 5 gegen den Kontaktträger 1 werden die mit dem Gehäuseteil 5 verbundenen Spannhülsen gegen die mit dem Kontaktträger 1 verbundenen Grundkörper verschoben (in den Figuren nicht dargestellt), so dass von den Hülsenkontakten 2 eine Kontaktkraft auf die Kontaktstifte 4 einwirkt und so eine vollständige elektrische Verbindung hergestellt ist. Wie aus der Figur 4 hervorgeht, ist nach bei der Verschiebung des Gehäuseteils 5 gegen den Kontaktträger 1 ein zum Gehäuseteil 5 gehörender zungenförmiger Abschnitt 27 in Richtung auf den Aggregateanschluß 3 verschoben, welcher dadurch auf einen hinteren Teil 28 des Rasthakens 13 trifft, dabei den vorderen Teil des Rasthakens 13 unter den ersten Vorsprung 12 drückt und dadurch den Hebel 7 in eine formschlüssige Verbindung mit dem Aggregateanschluß 3 bringt. In dieser Position ist der Rasthaken 13 von dem Aggregateanschluß 3 und dem zungenförmiger Abschnitt 27 beidseitig eingefasst und blockiert.The latching hook 13 of the lever 7 is now below the first projection 12 of the unit connection 3, but does not latch on this one, since no actuating force acting on one of the lever arms (8, 9) of the lever 7 acts and the lever 7 is also not resiliently biased , At the same time, the angled wall section 26 strikes the second projection 23 of the unit connection 3, as a result of which the displacement safety device 6, ie the positive connection between the housing part 5 and the contact carrier 1, is released. As a result, the housing part 5 is now displaceable against the contact carrier 1.
When moving the housing part 5 against the contact carrier 1, the clamping sleeves connected to the housing part 5 are moved against the main body connected to the contact carrier 1 (not shown in the figures), so that a contact force acts on the contact pins 4 of the sleeve contacts 2 and so on full electrical connection is made. Like from the FIG. 4 It can be seen that, upon displacement of the housing part 5 against the contact carrier 1 to a housing part 5 belonging tongue-shaped portion 27 in the direction of the Aggregate connection 3 shifted, which thereby hits a rear portion 28 of the latching hook 13, thereby pressing the front part of the latching hook 13 under the first projection 12 and thereby brings the lever 7 in a positive connection with the unit connection 3. In this position, the latching hook 13 is enclosed by the unit connection 3 and the tongue-shaped portion 27 on both sides and blocked.

Durch die seitliche Verschiebung des Rasthakens 13 durch den zungenförmigen Abschnitt 27 des Gehäuseteils 5 wird der erste Hebelarm 8 des Hebels 7 um seine Drehachse 29 gedreht. Allerdings wird dabei die Verschiebung des zweiten Hebelarms 9 durch den oberen Teil des zungenförmigen Abschnitt 27 blockiert, so dass sich in dem Hebel 7 eine Federspannung aufbaut. Bei der weiteren senkrecht nach unten verlaufenden Bewegung des zungenförmigen Abschnitts 27 wird der zweite Hebelarm 9 schließlich freigegeben und rastet, aufgrund seiner Federspannung, mit einem angeformten Rastelement 24 formschlüssig hinter einer Kante 31 des zungenförmigen Abschnitts 27 ein und arretiert damit das Gehäuseteil 5, wobei ein akustisch deutlich wahrnehmbares Rastgeräusch und eine haptisch wahrnehmbare Erschütterung des Gehäuseteils 5 entsteht.By the lateral displacement of the latching hook 13 through the tongue-shaped portion 27 of the housing part 5, the first lever arm 8 of the lever 7 is rotated about its axis of rotation 29. However, while the displacement of the second lever arm 9 is blocked by the upper part of the tongue-shaped portion 27, so that builds up a spring tension in the lever 7. In the further vertically downward movement of the tongue-shaped portion 27 of the second lever arm 9 is finally released and locked, due to its spring tension, with a molded locking element 24 positively behind an edge 31 of the tongue-shaped portion 27 and thus locks the housing part 5, wherein a acoustically distinct catching noise and a haptic perceptible vibration of the housing part 5 is formed.

Anschließend kann der zweite Hebelarm 9 noch durch den gegen das Gehäuseteil 5 verschiebbaren Riegel 11 in der erreichten Position gesichert werden. Die so vollständig miteinander verbundenen Steckverbinderteile zeigt die Figur 5.Subsequently, the second lever arm 9 can still be secured by the displaceable against the housing part 5 bolt 11 in the reached position. The so completely interconnected connector parts shows the FIG. 5 ,

Der einzige beim Zusammenfügen der Steckverbinderteile unter einer Federkraft auftretende, und damit akustisch und haptisch wahrnehmbare Rastvorgang tritt somit erst zum Abschluss aller relevanten Fügevorgänge (bis auf das Verschieben des Riegels 11, dessen Position aber auf optischem Wege kontrolliert werden kann) auf und setzt einen korrekten Ablauf der vorherigen Montageschritte voraus. Zur Erzeugung einer Federspannung in den Hebelarmen (8, 9) ist nämlich eine Verschiebung des Gehäuseteils 5 gegen den Kontaktträger 1 erforderlich, welche nur erfolgen kann, wenn die Verschiebesicherung 6 gelöst ist, was wiederum voraussetzt, dass der Kontaktträger 1 seine Endstellung am Aggregateanschluß 3 erreicht hat, wodurch wiederum die korrekte elektrische Kontaktgabe zwischen dem Hülsenkontakten 2 und den Kontaktstiften 4 sichergestellt ist. Das Auftreten des einzigen Rastgeräusch kann daher als Bestätigungssignal für eine korrekt und vollständig montierte Steckverbindung genutzt werden.The only occurring when joining the connector parts under a spring force, and thus acoustically and haptically perceptible locking process thus occurs only to complete all relevant joining operations (except for the displacement of the bolt 11, whose position can be controlled by optical means) on and sets a correct Expiration of the previous assembly steps ahead. To generate a spring tension in namely the lever arms (8, 9) is a displacement of the housing part 5 against the contact carrier 1 is required, which can only take place when the anti-displacement device 6 is released, which in turn requires that the contact carrier 1 has reached its end position on the unit connection 3, which in turn the correct electrical contact between the sleeve contacts 2 and the contact pins 4 is ensured. The occurrence of the single click sound can therefore be used as a confirmation signal for a correct and fully assembled connector.

Die durch den Hebel 7 hergestellte formschlüssige Verbindung zwischen dem Aggregateanschluß 3 und dem Kontaktträger 1 ist selbsthemmend ausgebildet. Durch den zungenförmigen Abschnitt 27 wird der Rasthaken 13 am ersten Hebelarm 8 des Hebels 7 unter den Vorsprung 12 am Aggregateanschluß 3 gedrückt. Diese Verbindung kann nicht ohne weiteres durch Verschieben des Gehäuseteils 5 gelöst werden, da eine Verschiebung des zungenförmigen Abschnitts 27 durch den zweiten Hebelarm 9 des Hebels 7 blockiert wird.The positive connection produced by the lever 7 between the unit connection 3 and the contact carrier 1 is designed to be self-locking. By the tongue-shaped portion 27 of the latching hook 13 is pressed on the first lever arm 8 of the lever 7 under the projection 12 on the unit connection 3. This connection can not be easily solved by moving the housing part 5, since a displacement of the tongue-shaped portion 27 is blocked by the second lever arm 9 of the lever 7.

Um dennoch eine bedarfsweise Trennung der Steckverbinderteile zu ermöglichen, ohne dass hierzu Eingriffe mit einem Werkzeug erforderlich werden, ist es vorteilhaft eine Betätigungslasche 10 vorzusehen, durch die eine Trennung der verbundenen Steckverbinderteile auf besonders einfache Weise eingeleitet werden kann.In order to still allow a need-based separation of the connector parts, without requiring intervention with a tool, it is advantageous to provide an actuating tab 10 can be initiated by the separation of the connected connector parts in a particularly simple manner.

Die Betätigungslasche 10 ist als ein zum zungenförmigen Abschnitt 27 paralleler beweglicher Streifen ausgebildet, der mit einem Endabschnitt an dem zungenförmigen Abschnitt 27 angeformt ist und der mit dem anderen Endabschnitt einen Betätigungsknopf 30 ausbildet. Der Betätigungsknopf 30 ist derart geformt und angeordnet, dass er an dem hinter dem zungenförmigen Abschnitt 27 eingerasteten Abschnitt des Hebels 7 anliegt. Wird eine Druckbetätigung auf den Betätigungsknopf 30 ausgeübt, so schiebt seine rückwärtige Fläche den eingerasteten zweiten Hebelarm 9 von der Kante 31 des zungenförmigen Abschnitts 27 weg, wodurch die Arretierung des zungenförmigen Abschnitts 27 frei wird. Zugleich wird durch eine Verschwenkung des zungenförmigen Abschnitts 27 der Rasthaken 13 entlastet. Durch die Druckeinwirkung auf den zweiten Hebelarm 9 wird über die Drehachse 29 eine Drehbewegung auf den ersten Hebelarm 8 übertragen, durch die der Rasthaken 13 von dem ersten Vorsprung 12 des Aggregateanschlusses 3 wegbewegt wird. Damit ist auch die formschlüssige Verbindung zwischen dem Rasthaken 13 und dem Aggregateanschluß 3 gelöst. Das Gehäuseteil 5 ist nun gegen den Kontaktträger 1 verschiebbar, wobei zum Verschieben lediglich noch die Kraft zum Lösen der Kontaktkräfte an den Spannhülsen aufgebracht werden muss.The actuating tab 10 is formed as a tongue-shaped portion 27 parallel movable strip, which is integrally formed with one end portion of the tongue-shaped portion 27 and forms with the other end portion of an operating knob 30. The operating knob 30 is shaped and arranged so that it rests against the latched behind the tongue-shaped portion 27 portion of the lever 7. If a pressure operation is exerted on the actuating button 30, so pushes his rear surface of the latched second lever arm 9 away from the edge 31 of the tongue-shaped portion 27, whereby the locking of the tongue-shaped portion 27 is free. At the same time, the latching hook 13 is relieved by a pivoting of the tongue-shaped portion 27. By the action of pressure on the second lever arm 9, a rotational movement is transmitted to the first lever arm 8 via the rotation axis 29, by which the latching hook 13 is moved away from the first projection 12 of the unit connection 3. Thus, the positive connection between the latching hook 13 and the unit connection 3 is solved. The housing part 5 is now displaceable against the contact carrier 1, wherein only the force for releasing the contact forces must be applied to the clamping sleeves for moving.
