Nach dem Zusammenstecken von Stecker und Gegenstecker wird das Sekundärverriegelungselement eingesetzt, um mittels geeignet ausgebildeter Rastarme ein unbeabsichtigtes Lösen der Verbindung zu verhindern.The US 6,491,542 describes a connector assembly having a secondary locking element in the form of a mechanical slider. After plugging plug and mating connector, the secondary locking element is used to prevent accidentally released by means of appropriately trained locking arms unintentional connection.

Die EP 0 655 807 A2 betrifft eine elektrische Steckverbindung mit einem separaten Sicherungselement. Das Sicherungselement wird nach Schließen der Verbindung von Stecker und Gegenstecker in eine entsprechende Aussparung in den Steckern eingesetzt. Nur bei korrekter Verbindung von Stecker und Gegenstecker lässt sich das Sicherungselement vollständig einfügen, wodurch eine visuelle Überprüfung der korrekten Steckverbindung sichergestellt werden soll.The EP 0 655 807 A2 relates to an electrical connector with a separate fuse element. The fuse element is inserted after closing the connection of plug and mating connector in a corresponding recess in the connectors. Only with correct connection of plug and mating connector, the fuse element can be completely inserted, whereby a visual check of the correct connector is to be ensured.

Die US 6,579,118 beschreibt eine elektrische Steckerverbindung mit Stecker und Gegenstecker sowie einem separaten Sicherungselement, das im gesteckten Zustand von Stecker und Gegenstecker auf die Verbindung gesteckt wird, um ein unbeabsichtigtes Lösen der Verbindung zu verhindern.The US 6,579,118 describes an electrical plug connection with plug and mating connector and a separate fuse element that is plugged in the mated state of the plug and mating connector on the connection to prevent inadvertent release of the connection.

Die EP 1 369 965 A2 beschreibt ein Verbindersystem bestehend aus Stecker, Gegenstecker und zugehöriger Sekundärverriegelung. Die Sekundärverriegelung wird in die miteinander verbundenen Stecker eingeführt, um mittels entsprechender Rastarme ein unbeabsichtigtes Lösen der Verbindung zu verhindern.The EP 1 369 965 A2 describes a connector system consisting of plug, mating connector and associated secondary locking. The secondary lock is inserted into the interconnected connector to prevent accidental release of the connection by means of corresponding latching arms.

Die US 6 270 368 offenbart eine Steckverbindung, die mittels einer Metallschelle zusätzlich gesichert ist.The US 6,270,368 discloses a plug connection, which is additionally secured by means of a metal clamp.

In der DE 101 51 956 A1 ist ein Steckverbinder mit Sekundärverriegelung offenbart, bei der die Sekundärverriegelung während des Steckvorgangs durch den Gegenstecker aus einer Vorraststellung gelöst wird. Nach dem vollständigen Zusammenfügen von Stecker und Gegenstecker wird die Sekundärverriegelung in ihre Endstellung gebracht.In the DE 101 51 956 A1 discloses a connector with secondary locking, in which the secondary lock is released during the insertion process by the mating connector from a pre-locked position. After complete assembly of plug and mating connector, the secondary lock is brought into its final position.

In der US 6,077,101 ist eine Steckverbindung offenbart, bei der eine Sekundärverriegelung in Steckrichtung auf einen Stecker aufgeschoben wird und mittels Rastvorsprüngen Stecker und Gegenstecker miteinander gegen ein unbeabsichtigtes Lösen sichert.In the US 6,077,101 is a connector disclosed in which a secondary lock is pushed in the direction of insertion on a plug and secures by means of latching projections plug and mating connector against unintentional release.

Aus der DE 698 18 788 ist eine Steckverbinderanordnung bekannt, bei der ein Stecker auf einen zylinderförmigen Teil unter einen Winkel von 90° zur Zylinderachse aufgesteckt wird. Bei dem zylinderförmigen Teil handelt es sich um eine Einspritzdüse für Dieselmotoren. Der Stecker weist Verriegelungsarme aus gebogenem Stahldraht auf, mit Rastnasen, die hinter Schultern greifen, die auf dem Zylindermantel der Einspritzdüse ausgeformt sind. Die Haltewirkung der Rastarme ist sehr straff, da die aus Stahldraht geformten Rastarme eine hohe Federkraft aufweisen können. Das Lösen der Steckverbindung gestaltet sich relativ einfach, da im kabelanschlussseitigen Teil des Steckers die Stahldrähte zusammengedrückt, d. h. aufeinander zu gedrückt werden, sodass sich durch eine Abstützung der Draht-rastarme in deren mittleren Bereich ein "Wippeneffekt" ergibt, sodass die Rastnasen aus ihrer Verraststellung gelöst werden.From the DE 698 18 788 a connector assembly is known in which a plug is plugged onto a cylindrical part at an angle of 90 ° to the cylinder axis. The cylindrical part is an injection nozzle for diesel engines. The plug has locking arms made of bent steel wire, with locking lugs which engage behind shoulders, which are formed on the cylinder jacket of the injection nozzle. The holding action of the latching arms is very taut, since the latching arms formed from steel wire can have a high spring force. The release of the connector is relatively simple, since in the cable connection side part of the plug, the steel wires are compressed, ie pushed towards each other, so that by a support of the wire latching arms in the central region of a "seesaw effect" results, so that the locking lugs from their Verraststellung be solved.

Nachteilig bei dieser Steckverbinderanordnung ist, dass ein nicht vollständiges Verrasten der Rastarme nicht ausgeschlossen werden kann und auch ein unbeabsichtigtes Lösen der Steckverbindung, etwa durch einen ruckartigen Zug am Verbinderkabel möglich ist.A disadvantage of this connector arrangement is that a non-complete latching of the latching arms can not be excluded and also an unintentional release of the connector, such as a jerky train on the connector cable is possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Steckverbinderanordnung anzugeben, bei der ein unvollständiges Zusammenstecken ausgeschlossen ist und ein unbeabsichtigtes Lösen der Steckverbindung unmöglich gemacht ist.The invention has for its object to provide a connector assembly in which an incomplete mating is excluded and unintentional release of the connector is made impossible.

Diese Aufgabe wird anspruchsgemäß gelöst.This task is solved according to the claims.

In den Unteransprüchen sind Merkmale bevorzugter Ausführungsformen der vorliegenden Erfindung gekennzeichnet.In the subclaims features of preferred embodiments of the present invention are characterized.

Die Erfindung geht von dem Grundgedanken aus eine Konstruktion zu schaffen, bei der es bei einem unvollständig ausgeführten Steckvorgang unmöglich ist, die Sekundärverrieglung in ihre Endstellung zu bringen und bei der durch das Verharren der Sekunderverriegelung in ihrer Vorraststellung sichtbar ist, dass Stecker und Gegenstecker nicht zusammengesteckt sind.The invention is based on the idea of creating a construction in which it is impossible for an incomplete plug-in operation to bring the Sekundärverrieglung in its final position and is visible by the persistence of Sekunderverriegelung in its pre-locking position that plug and mating connector not mated are.

Die erfindungsgemäße Steckverbinderanordnung eignet sich insbesondere für die Verkabelung einer im Wesentlichen zylinderförmigen Dieseleinspritzdüse, zu deren Achse der Stecker in einem Winkel von 90° aufgesteckt wird.The connector assembly according to the invention is particularly suitable for the wiring of a substantially cylindrical diesel injector to the axis of the plug is plugged at an angle of 90 °.

Fig. 1 shows an embodiment of a plug of the connector assembly according to the invention. The plug 1 has a housing 23 with aprons 7 integrally formed thereon and a secondary lock 3. In the housing, a contact carrier block 18 is mounted, which projects into the space enclosed by the aprons 7 space and which is sealed with a sealing ring 19 relative to the plug housing 23. On the outside of the aprons 7, the first locking arms 2 are mounted in guide grooves 24 in the form of a bent steel wire bow. The aprons 7 have at their head end tabs 8, which form an opening 25 into which the front end 26 of the second locking arms 9 of the secondary lock 3 are inserted in the final locked position. In addition, openings 11 are formed centrally in the front region of the skirts 7, through which the latching lugs 5 and 10 of the first and second latching arms 2 and 9 protrude into the space enclosed by the skirts 7.

Die Sekundärverriegelung 3 und das Gehäuse 23 weisen am kabelseitigen Ende des Steckers 1 Handhabungsflächen 27 bzw. 28 auf, auf die der Anwender beim Einstecken des Steckers 1 in den Steckbereich des Gegensteckers 4 drückt, um zuerst den Stecker 1 im Gegenstecker 4 zu verrasten und anschließend die Sekundärverriegelung 3 in ihre Endraststellung zu bringen.The secondary lock 3 and the housing 23 have at the cable end of the plug 1 handling surfaces 27 and 28, to which the user when inserting the plug 1 in the mating area the mating connector 4 presses to first lock the connector 1 in the mating connector 4 and then bring the secondary lock 3 in its final locked position.

Das Steckergehäuse 23 weist ferner in ihrem hinteren Teil sich gegenüberliegende Einbuchtungen 29 auf, die sich in Einbuchtungen 30 in der Sekundärverriegelung 3 fortsetzen und die das hintere Ende der ersten Rastarme 2 in Form von Stahldrahtbügeln frei zugänglich machen.The plug housing 23 also has in its rear part opposite recesses 29, which continue in indentations 30 in the secondary latch 3 and make the rear end of the first latching arms 2 in the form of steel wire hangers freely accessible.

Beim Lösen der Steckverbindung überführt man zuerst die Sekundärverriegelung 3 durch Ziehen an der Handhabe 28 in ihre Vorraststellung. Wenn dies geschehen ist, fluchten die Ausnehmungen 29 und 30, sodass nun die Drahtbügel der ersten Rastarme 2 mit zwei Fingern zusammengedrückt werden können. Dadurch, dass die Drahtbügel auf dem Boden der Nuten 24 aufliegen ergibt sich ein "Wippeneffekt", sodass der vordere Teil der Drahtbügel mit den Rastnasen 5 aus den Nuten 24 herausgehoben werden. Damit löst man den Eingriff der Rastnasen hinter den Schultern 6 des Gegensteckers, 4 und der Stecker 1 kann abgezogen werden.When releasing the connector is first transferred to the secondary lock 3 by pulling on the handle 28 in its pre-locked position. When this is done, the recesses 29 and 30 are aligned, so that now the wire hanger of the first locking arms 2 can be compressed with two fingers. The fact that the wire clamps rest on the bottom of the grooves 24 results in a "seesaw effect", so that the front part of the wire hanger with the locking lugs 5 are lifted out of the grooves 24. This triggers the engagement of the locking lugs behind the shoulders 6 of the mating connector, 4 and the connector 1 can be removed.

Fig. 2 zeigt eine perspektivische Ansicht einer Einspritzdüse 22 mit einem Gegensteckerbereich 4, auf den der Stecker 1 in einem Winkel von 90° zu der Längsachse der zylinderförmigen Einspritzdüse aufgesteckt wird. Der Gegenstecker 4 weist eine Ausnehmung 20 auf, die den Kontaktträgerblock 18 teilweise aufnimmt. Die Stirnkante 20 drückt dabei gegen den Dichtring 19, sodass die Kontakte von Stecker und Gegenstecker 1, 4 gegenüber Feuchtigkeit und Schmutz geschützt sind. Fig. 2 shows a perspective view of an injection nozzle 22 with a mating connector portion 4, on which the plug 1 is plugged at an angle of 90 ° to the longitudinal axis of the cylindrical injection nozzle. The mating connector 4 has a recess 20 which receives the contact carrier block 18 partially. The front edge 20 presses against the sealing ring 19 so that the contacts of plug and mating connector 1, 4 are protected against moisture and dirt.

Die Fig. 3 bis 12 zeigen in chronologischer Reihenfolge den Montageablauf. Dabei sind der Stecker 1 im Längsschnitt entlang der Steckachse und der Steckbereich der zylinderförmigen Einspritzdüse 22 im Querschnitt gezeigt. Zu beachten ist, dass die Schnitte unterhalb der Längsmittelachse des Steckers 1 genau in der Ebene der Längsmittelachse gezeichnet ist, wohingegen der Schnitt oberhalb der Längsmittelachse demgegenüber etwas parallel verschoben ist. Damit wird verdeutlicht, dass der Rastarm 9 der Sekundärverriegelung 3 im Querschnitt ein Profil aufweist, das in seiner Mitte dicker ist und die Rastnase 10 aufweist, wohingegen die Seitenflanken des Rastarms 9 dünner ausgeführt sind und am freien Ende des Rastarms 9 Rastnasen 13 ausgeformt sind, die in komplementäre Vertiefungen 14 auf der Außenseite der Schürze 7 am Rand der Öffnung 11 ausgebildet sind.The Fig. 3 to 12 show in chronological order the assembly process. The plug 1 are in longitudinal section along the thru axle and the mating portion of the cylindrical injector 22 is shown in cross-section. It should be noted that the sections below the longitudinal central axis of the plug 1 is drawn exactly in the plane of the longitudinal central axis, whereas the section above the longitudinal central axis is displaced somewhat in parallel. This makes it clear that the locking arm 9 of the secondary lock 3 has a profile in cross-section, which is thicker in the middle and the locking lug 10, whereas the side edges of the latching arm 9 are made thinner and at the free end of the latching arm 9 locking lugs 13 are formed, which are formed in complementary recesses 14 on the outside of the skirt 7 at the edge of the opening 11.

In Fig. 3 sind die einzelnen Teile im Wesentlichen vollständig mit Bezugszeichen versehen. in den folgenden Fig. 4 bis 12 sind lediglich solche Bezugszeichen eingetragen, die zur Erläuterung der jeweiligen Montageetappe erforderlich sind.In Fig. 3 the individual parts are substantially completely provided with reference numerals. in the following 4 to 12 only those reference numerals are entered, which are required to explain the respective installation stage.

In der in Fig. 3 gezeigten Stellung ist der Stecker 1 noch nicht im Kontakt mit dem Gegenstecker 4. Die Sekundärverriegelung 3 ist über die eben erläuterten Rastnasen 13 bzw. Rastnuten 14 in Vorraststellung gesichert. Sowohl die Rastnase 5 des ersten Rastarms 2 als auch die Rastnase 10 des Rastarms 9 der Sekundärverriegelung 3 ragen in den von der Schürze 7 umgebenen Raum durch Öffnungen 11 in den Schürzen 7 hinein.In the in Fig. 3 shown position, the plug 1 is not yet in contact with the mating connector 4. The secondary lock 3 is secured via the above-explained locking lugs 13 and locking grooves 14 in the pre-locked position. Both the latching lug 5 of the first latching arm 2 and the latching lug 10 of the latching arm 9 of the secondary latching mechanism 3 protrude into the space surrounded by the skirting 7 through openings 11 in the skirts 7.

Bei der in Fig. 4 gezeigten Etappe berühren die Rastnasen 5 gerade den Gegenstecker 4 auf dem Körper der Einspritzdüse 22.
in der in Fig. 5 gezeigten Stellung ist der Kontaktträgerblock 18 schon teilweise in die Ausnehmung 20 des Gegensteckers 4 in der Einspritzdüse 22 eingeführt. Die Rastnasen 5 sind durch Gleiten auf den Rampen 12 von der Längsmittelachse des Steckers 1 weg verschoben worden. Die Rastnasen 5 liegen in dieser Etappe genau vor der Öffnung der Lasche 8 und versperren diese für den Zugang der freien Enden der Sekundärverriegelung 3. Die Rastnase 10 des zweiten Rastarms 9 der Sekundärverriegelung 3 berührt in dieser Stellung gerade die Rampe 12, der Rastarm 9 ist jedoch gegenüber seiner Ruhestellung noch nicht ausgelenkt. Somit ist die Sekundärverriegelung 3 über die Rastmittel 13, 14 noch in Vorraststellung arretiert.At the in Fig. 4 shown stage, the locking lugs 5 just touch the mating connector 4 on the body of the injection nozzle 22nd
in the in Fig. 5 shown position, the contact carrier block 18 is already partially inserted into the recess 20 of the mating connector 4 in the injection nozzle 22. The locking lugs 5 are by sliding on the ramps 12 have been moved away from the longitudinal center axis of the plug 1 away. The locking lugs 5 are in this stage just in front of the opening of the tab 8 and block this for the access of the free ends of the secondary latch 3. The latch 10 of the second latch arm 9 of the secondary latch 3 touches in this position just the ramp 12, the latching arm 9 but not yet distracted from his resting position. Thus, the secondary lock 3 is locked on the locking means 13, 14 still in the pre-locking position.

In der in Fig. 6 gezeigten Etappe ist dies nicht mehr der Fall, d. h. die zweiten Rastarme 9 der Sekundärverriegelung 3 sind durch das Gleiten der Rastnasen 10 auf den Rampen 12 auseinandergezogen, d. h. von der Längsmittelachse des Steckers 1 weggedrückt, sodass die Rastnase 13 des Rastarms 9 aus der Rastnut 14 auf der Außenseite der Schürze 7 herausgehoben ist. Somit stehen Rastnase und Rastnut 13, 14 nicht mehr in Eingriff und die Sekundärverriegelung 3 kann in Steckrichtung verschoben werden. Die Rastnase 5 des ersten Rastarms 2 versperrt weiterhin den Zugang der Lasche 8. Ferner ist der Kontaktträgerblock 18 so weit in die Aufnahme 20 eingedrungen, dass die Stirnkante 21 der Ausnehmung 20 mit dem Dichtring 19 in Kontakt steht und eine Abdichtung des Raums, in dem sich die Kontakte befinden, beginnt.In the in Fig. 6 this stage is no longer the case, ie the second latching arms 9 of the secondary latch 3 are pulled apart by the sliding of the locking lugs 10 on the ramps 12, ie pushed away from the longitudinal center axis of the plug 1, so that the latching lug 13 of the latching arm 9 from the latching groove 14th is lifted out on the outside of the skirt 7. Thus, locking lug and locking groove 13, 14 are no longer engaged and the secondary lock 3 can be moved in the direction of insertion. Furthermore, the contact carrier block 18 has penetrated so far into the receptacle 20 that the end edge 21 of the recess 20 is in contact with the sealing ring 19 and a seal of the space in which the contacts are starting.

Die Fig. 7 und 8 zeigen nochmals im Einzelnen das Lösen der Sekundärverriegelung 3 aus ihrer Vorraststellung und das Anstoßen der Spitzen der zweiten Rastarme 9 gegen die U-förmig gebogenen Rastnasen 5 der ersten Rastarme 2.The Fig. 7 and 8th again show in detail the release of the secondary lock 3 from its pre-locking position and the abutment of the tips of the second locking arms 9 against the U-shaped locking lugs 5 of the first locking arms. 2

In Fig. 9 ist die Rastnase 5 nun hinter die Schulter 6 im Gegenstecker 4 gesprungen, wodurch die Steckverbindung zwischen dem Stecker 1 und dem Gegenstecker 4 verrastet ist. Man erkennt ferner, dass der erste Rastarm 2 aus Stahldraht nunmehr wieder entspannt ist und der Drahtbügel in der Ausnehmung 29 wieder erscheint (was in den Etappen der Fig. 5 bis 8 nicht der Fall war). Gleichzeitig ist nun der Zugang zu der Öffnung in der Lasche 8 freigegeben, sodass die aus der Vorraststellung gelösten zweiten Rastarme 9 der Sekundärverriegelung 3 mit ihren Stirnenden in die Lasche 8 eindringen können. Dies ist in den Fig. 10 bis 12 gezeigt, wobei Fig. 10 das Heruntergleiten der Rastnasen 10 und 13 der zweiten Rastarme 9 an der Oberkante der Schulter 6 zeigt. Im oberen Kantenbereich der Spitzen der zweiten Rastarme 9 sind diese etwas angeschrägt, um das Einführen in die Öffnung der Lasche 8 zu erleichtern.In Fig. 9 is the locking lug 5 now jumped behind the shoulder 6 in the mating connector 4, whereby the connector between the plug 1 and the mating connector 4 is locked. It can also be seen that the first locking arm 2 made of steel wire now relaxed again is and the wire hanger in the recess 29 reappears (which in the stages of Fig. 5 to 8 not the case). At the same time access to the opening in the tab 8 is now released, so that the released from the pre-locking second locking arms 9 of the secondary latch 3 can penetrate with their front ends in the tab 8. This is in the 10 to 12 shown, where Fig. 10 the sliding down of the locking lugs 10 and 13 of the second latching arms 9 at the upper edge of the shoulder 6 shows. In the upper edge region of the tips of the second latching arms 9, these are slightly bevelled to facilitate insertion into the opening of the flap 8.

Fig. 11 zeigt das weitere Vordringen der zweiten Rastarme 9 in die Öffnung der Lasche 8 und Fig. 12 zeigt die zusammengesteckte Steckverbinderanordnung in ihrer Endraststellung. Man erkennt, dass die Rastnase 5 des ersten Rastarms 2 nicht mehr aus ihrer Verrastung hinter der Schulter 6 herausbewegt werden kann, da der Weg von der Längsmittelachse des Steckers 1 radial weg nach außen durch den durch die Lasche 8 gesicherten zweiten Rastarm 9 versperrt ist. Fig. 11 shows the further penetration of the second latching arms 9 in the opening of the tab 8 and Fig. 12 shows the mated connector assembly in its final locked position. It can be seen that the latching lug 5 of the first latching arm 2 can no longer be moved out of its latching behind the shoulder 6, since the path from the longitudinal center axis of the plug 1 is radially outwardly blocked by the secured by the tab 8 second latching arm 9.

Man erkennt ferner in Fig. 12, dass die Mulde 29 nicht mit der Mulde 30 (siehe Fig. 1) der Sekundärverriegelung fluchtet, sodass es schwierig ist, mit den Fingern den Drahtbügel der ersten Rastarme 2 herunterzudrücken.One recognizes further in Fig. 12 in that the trough 29 does not interfere with the trough 30 (see Fig. 1 ) of the secondary latch is aligned, so that it is difficult to press down with the fingers of the wire hanger of the first latching arms 2.

Das Lösen der Steckverbindung beginnt mit dem Abziehen der Sekundärverriegelung 3 aus ihrer Endraststellung in ihrer Vorraststellung. Dann fluchten die Vertiefungen 29 und 30 und der Drahtbügel der ersten Rastarme 2 wird für einen Zugriff mit zwei Fingern zugänglich.The release of the connector begins with the removal of the secondary latch 3 from its final locked position in its pre-locked position. Then the recesses 29 and 30 are aligned and the wire hanger of the first latch arms 2 becomes accessible for two-finger access.

Dann drückt man auf den Drahtbügel, sodass die Rastnasen 5 sich aus ihrer Verrastung hinter der Schulter 6 lösen und über der Rampe 12 stehen. Nun kann ein Abziehen des Steckers 1 vom Gegenstecker 4 erfolgen.Then you press on the wire hanger so that the locking lugs 5 are released from their catch behind the shoulder 6 and are above the ramp 12. Now, a removal of the plug 1 can be done by the mating connector 4.

Das vorstehend beschriebene Beispiel einer Ausführung der in den Ansprüchen beanspruchten Erfindung ist nicht einschränkend zu verstehen sondern dient lediglich illustrativen Zwecken. So ist beispielsweise die Form der Rampen 12 nicht zwingend gebogen, wie bei der Zylindermantelfläche einer Einspritzdüse sondern kann andere geeignete Formen, wie beispielsweise die einer gradlinigen Rampe, aufweisen. Bei dem ersten Rastarm muss es sich nicht um einen Drahtbügel handeln, es ist auch denkbar, Kunststoffrastarme zu verwenden. Die Form des Steckergehäuses bei dem gezeigten Ausführungsbeispiel wurde aus praktischen Erwägungen so gewählt, da sie Vorteile beim Spritzgießen hat. Jede andere nützliche Form ist denkbar, wobei kundenspezifische Wünsche, die sich aus einer vorgegebenen Form eines Gegensteckers ergeben, ohne Weiteres berücksichtigbar sind.The above-described example of an embodiment of the invention claimed in the claims is not intended to be limiting but is for illustrative purposes only. For example, the shape of the ramps 12 is not necessarily bent, as in the cylinder jacket surface of an injector, but may have other suitable shapes, such as a straight line ramp. The first latching arm does not have to be a wire bracket, it is also conceivable to use plastic latching arms. The shape of the plug housing in the illustrated embodiment has been chosen for practical reasons because it has advantages in injection molding. Any other useful form is conceivable, with customer-specific wishes, which result from a given form of a mating connector, which can be taken into account without further ado.

Einem ersten und üblichen Vorgehensweise entsprechend druck zum Einstecken der Anwender zuerst auf den Handhabungsfläche 27 um den Stecker 1 im Gegenstecker 4 zu verrasten und anschließend auf den Handhabungsfläche 28 um die Sekundärverriegelung 3 in ihre Endraststellung zu bringen. Ein weiteres Vorteil der Erfindung besteht aber darin, dass es auch möglich ist, das Einstecken in einem Zug vorzunehmen, indem es genügt auf den Handhabungsfläche 28 zu drücken um die Sekundärverriegelung 3 zuerst samt zusammen verrastetem Gehäuse 23 bis dieses verrastet in voll gestecktem Zustand und anschließend allein bis Endrasstellung zu verschieben.A first and usual approach according to pressure to insert the user first on the handling surface 27 to lock the connector 1 in the mating connector 4 and then bring to the handling surface 28 to the secondary latch 3 in its final locked position. Another advantage of the invention, however, is that it is also possible to make the plugging in a train by pressing on the handling surface 28 to push the secondary latch 3 together with the first latched together housing 23 to this locked in fully inserted state and then to move alone until Endrasstellung.
