Description

Die Erfindung betrifft eine Kupplung oder einen Stecker einer Steckverbindung, wobei ein Verriegelungselement vorgesehen ist, welches bewirkt, dass Kupplung und Stecker nach dem Zusammensetzen nicht mehr voneinander getrennt werden können, gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a coupling or a plug of a plug connection, wherein a locking element is provided, which causes coupling and plug after assembly can not be separated from each other, according to the features of the preamble of claim 1.

Aus der EP 0 854 546 B1 ist grundsätzlich eine gattungsgemäße Steckverbindung bekannt. Diese Steckverbindung umfaßt eine Kupplung (auch Buchse genannt) sowie einen Stecker, die zu einer Steckverbindung zusammengesteckt werden können. Aufgrund von rauhen Umgebungsbedingungen (wie insbesondere Vibrationen) weist diese Steckverbindung eine erste Rastverbindung auf, die bewirkt, dass Kupplung und Stecker nicht ohne weiteres voneinander getrennt werden können. Da eine solche erste Rastverbindung den gewünschten Anforderungsbedingungen, die insbesondere beim Einsatz solcher Steckverbindungen in Fahrzeugen herrschen, nicht ausreichend ist, sind weitere Rastmittel in Form eines Verriegelungselementes vorgesehen. Dieses aus der EP 0 854 546 B1 bekannte Verriegelungselement wird direkt auf dem Gehäuse der Kupplung angeordnet und ist dort längsverschiebbar. Nachdem die Kupplung sowie das Verriegelungselement getrennt voneinander hergestellt worden sind, wird das Verriegelungselement in einer ersten Stellung, der Vorverraststellung, an dem Gehäuse der Kupplung festgelegt. Hierbei sind das Verriegelungselement sowie die Kupplung derart gestaltet, dass das Verriegelungselement nicht aus seiner Vorverraststellung herausbewegt werden kann, bis Stecker und Kupplung zusammengesteckt worden sind. Erst wenn sich der Stecker vollständig in der Kupplung befindet, ist es möglich, das Verriegelungselement von seiner Vorverraststellung in eine Endverraststellung zu bewegen, um damit einerseits zu gewährleisten, dass Stecker und Kupplung vollständig zusammengesteckt worden sind und andererseits eine weitere Verrastung gegen ungewolltes Lösen der Steckverbindung zu realisieren.From the EP 0 854 546 B1 is basically a generic connector known. This connector comprises a coupling (also called socket) and a plug that can be plugged together to form a plug connection. Due to harsh environmental conditions (in particular vibrations), this connector has a first latching connection, which causes the coupling and plug can not be easily separated from each other. Since such a first latching connection is not sufficient for the desired requirements, which prevail in particular when such plug connections are used in vehicles, further latching means in the form of a locking element are provided. This from the EP 0 854 546 B1 known locking element is arranged directly on the housing of the coupling and is longitudinally displaceable there. After the coupling and the locking element have been produced separately, the locking element is fixed in a first position, the Vorverraststellung, on the housing of the coupling. Here, the locking element and the coupling are designed such that the locking element can not be moved out of its Vorverraststellung until plug and coupling have been put together. Only when the plug is completely in the coupling, it is possible to move the locking element from its pre-locked position into a Endverraststellung, so as to ensure on the one hand that plug and coupling have been completely mated and on the other hand, a further locking against unintentional release of the connector to realize.

Das Verriegelungselement, welches aus der EP 0 854 546 B1 bekannt ist, weist Führungsnuten auf, die mit Führungsrippen an der Kupplung korrespondieren. Dabei ist der Abstand zwischen den jeweiligen Führungsnuten und der Abstand zwischen den jeweiligen Führungsrippen so festgelegt, dass der Abstand zwischen den Führungsnuten größer ist als der Abstand zwischen den Führungsnuten und wenn den jeweiligen Führungsrippen ermöglicht wird, dass die entsprechenden Führungsrippen dort eingesetzt werden, vorbestimmte Bereiche der Führungsnuten mit den entsprechenden Bereichen der jeweiligen Führungsrippen angepaßt werden, so dass bestimmte Vorbelastungskräfte bewirkt werden, die zwischen den Führungsrippen und den Führungsnuten aufgebracht werden. Damit soll sichergestellt werden, dass nach der Festlegung des Verriegelungselementes in seiner Endverraststellung ein ungewolltes Lösen des Verriegelungselementes aufgrund von den herrschenden Umgebungsbedingungen vermieden wird. Hier hat sich allerdings herausgestellt, dass diese Vorbelastungskräfte zur dauerhaften Festlegung des Verriegelungselementes in seiner Endverraststellung nicht ausreichend sind, so dass es sich aus dieser Endverraststellung heraus bewegen kann und die Gefahr des Lösens der Steckverbindung besteht.The locking element, which from the EP 0 854 546 B1 is known, has guide grooves which correspond with guide ribs on the coupling. In this case, the distance between the respective guide grooves and the distance between the respective guide ribs is set so that the distance between the guide grooves is greater than the distance between the guide grooves and if the respective guide ribs are allowed that the corresponding guide ribs are used there, predetermined areas the guide grooves are adapted to the respective areas of the respective guide ribs, so that certain biasing forces are applied, which are applied between the guide ribs and the guide grooves. This is to ensure that after the determination of the locking element in its Endverraststellung an accidental release of the locking element due to the prevailing environmental conditions is avoided. Here, however, it has been found that these preload forces are not sufficient for permanent fixing of the locking element in its Endverraststellung, so that it can move out of this Endverraststellung out and there is a risk of loosening the connector.

Aus der DE 195 25 413 C2 ist eine Vorrichtung zum Erkennen eines vollständigen Eingriffs zweier zusammenpassender Steckverbinderteile bekannt, die ein erstes Steckergehäuse und ein zweites Steckergehäuse aufweisen, mit einer Eingriffserkennungsvorrichtung, wobei das erste Steckergehäuse einen federnden Verriegelungsarm aufweist, an dem ein Verriegelungsvorsprung ausgebildet ist, wobei weiterhin das zweite Steckergehäuse einen Eingriffsvorsprung aufweist, der mit dem Verriegelungsvorsprung des Verriegelungsarms des ersten Steckergehäuses kuppelbar ist, und die Eingriffserkennungsvorrichtung an dem ersten Steckergehäuse in dessen Längsrichtung verschiebbar angeordnet und mit dem zweiten Steckergehäuse kuppelbar ist. Weiterhin ist hierbei vorgesehen, dass der federnde Verriegelungsarm einen Führungsabschnitt aufweist sowie die Eingriffserkennungsvorrichtung einen Betätigungsabschnitt und einen federnden Eingriffserkennungsarm aufweist, wobei der Betätigungsabschnitt mit einem Eingriffsabschnitt versehen ist, der in gleitendem Eingriff mit dem Führungsabschnitt steht und an dem federnden Eingriffserkennungsarm ein Vorsprung angeordnet ist, der mit dem Verriegelungsvorsprung in Eingriff bringbar ist, wobei beim Kuppeln der Steckverbinderteile miteinander der Vorsprung in gleitenden Kontakt mit der jeweiligen unteren Endfläche des Eingriffsvorsprungs und des Verriegelungsvorsprungs bringbar ist. Zum Kuppeln der Eingriffserkennungsvorrichtung ist es also erforderlich, dass dessen Vorsprung aus einer ersten Ebene in eine weitere Ebene angehoben wird, wobei der Vorsprung nach dem Zusammensetzen der beiden Steckverbinderteile wieder in die Ausgangsebene sich zurückbewegt. Außerdem funktioniert die Eingriffserkennungsvorrichtung nur dann, wenn sie führend an einem der Steckverbinderteile gelagert ist. US 5 120 255 A offenbart den Oberbegriff des Anspruchs 1. Der Erfindung liegt daher die Aufgabe zugrunde, eine Kupplung oder einen Stecker einer Steckverbindung mit ersten Rastmitteln sowie einem zusätzlichen Verriegelungselement bereitzustellen, wobei diese Anordnung einfach aufgebaut sein soll, bei bekannten Kupplungen oder Steckern nachrüstbar ist und vor allen Dingen ein unbeabsichtigtes Herausbewegen des Verriegelungselementes aus seiner Endverraststellung zu vermeiden ist.From the DE 195 25 413 C2 a device for detecting a complete engagement of two mating connector parts is known, having a first connector housing and a second connector housing, with an engagement recognition device, wherein the first connector housing has a resilient locking arm on which a locking projection is formed, further wherein the second connector housing an engagement projection which is engageable with the locking projection of the lock arm of the first connector housing, and the engagement recognition device is slidably disposed on the first connector housing in the longitudinal direction thereof and is detachable with the second connector housing. Furthermore, it is provided here that the resilient locking arm has a guide section and the engagement recognition device has an actuating section and a resilient engagement recognition arm, wherein the actuating section is provided with an engagement section which is in sliding engagement with the guide section and a projection is arranged on the resilient engagement recognition arm, which is engageable with the locking protrusion, wherein upon coupling of the connector parts together, the protrusion is slidably engageable with the respective lower end surface of the engaging protrusion and the locking protrusion. To couple the engagement recognition device, it is therefore necessary that its projection is raised from a first plane to a further plane, wherein the Projection after reassembling the two connector parts back into the starting plane moves back. In addition, the engagement recognition device operates only when it is mounted leader on one of the connector parts. US 5 120 255 A discloses the preamble of claim 1. The invention is therefore based on the object to provide a coupling or plug of a connector with first locking means and an additional locking element, this arrangement should be simple, with known couplings or connectors can be retrofitted and above all unintentional moving out of the locking element is to be avoided from its Endverraststellung.

Diese Aufgabe ist durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.

Erfindungsgemäß ist vorgesehen, dass das Verriegelungselement an den ersten Rastmitteln angeordnet ist. Dies hat den Vorteil, dass schon vorhandene Kupplungen oder Stecker, die diese ersten Rastmittel aufweisen, einfach mit dem Verriegelungselement nachgerüstet werden können. Weiterhin wird in besonders vorteilhafter Weise durch das gleichzeitige Zusammenspiel von ersten Rastmitteln und Verriegelungselement eine einfache Handhabung der Doppelverriegelung beim Zusammenstecken von Kupplung und Stecker zu einer Steckverbindung gewährleistet und verhindert, dass sich nach dem Zusammenstecken der Steckverbindung und dem Bewegen des Verriegelungselementes von seiner Vorverraststellung in seine Endverraststellung das Verriegelungselement aus dieser Endverraststellung herausbewegen kann. Damit ist das Verriegelungselement in seiner Endverraststellung wirksam und vor allen Dingen dauerhaft festgelegt.According to the invention it is provided that the locking element is arranged on the first locking means. This has the advantage that already existing couplings or plugs, which have these first locking means, can be easily retrofitted with the locking element. Furthermore, it is ensured in a particularly advantageous manner by the simultaneous interaction of first locking means and locking element easy handling of the double locking when mating coupling and plug to a plug connection and prevents after plugging together the connector and moving the locking element of its Vorverraststellung in his Endverraststellung the locking element can move out of this Endverraststellung. Thus, the locking element is effective in its Endverraststellung and permanently fixed above all.

Figur 1 zeigt die dreidimensionale Ansicht einer Kupplung 10, die nach dem Zusammensetzen mit einem korrespondierenden Stecker eine Steckverbindung bilden. Die Kupplung 10 weist ein beispielsweise aus Kunststoff bestehendes Gehäuse 11 auf, welches kabelseitig einen Schutzkragen 12 aufweisen kann. Innerhalb des Gehäuses 11 ist ein Aufnahmeraum 13 vorgesehen, in dem die für die Steckverbindung auf Seiten der Kupplung 10 erforderlichen Kontaktpartner angeordnet, in Figur 1 aber der Einfachheit halber nicht dargestellt sind. Die Form, die Ausgestaltung und die Anzahl sowie Anordnung der Kontaktpartner in dem Aufnahmeraum 13 ist nicht Gegenstand der Erfindung und in Abhängigkeit der Einsatzbedingungen der Kupplung 10 wählbar. Weiterhin weist die Kupplung 10 erste Rastmittel 14 auf, die als eine Art Wippe ausgebildet sind, wozu eine Platte über einen Steg an dem Gehäuse 11 der Kupplung 10 befestigt ist. In besonders vorteilhafter Weise werden die Rastmittel 14 schon mit Herstellung des Gehäuses 11 der Kupplung 10 hergestellt. Dies kann beispielsweise in einem Kunststoffspritzgußverfahren erfolgen. Die Platte der ersten Rastmittel 14 weist parallel zueinander verlaufende Stege sowie eine Ausnehmung auf, die im Zusammenhang mit dem in den folgenden Figuren noch zu beschreibenden Verriegelungselement von Bedeutung sind. Ebenso wird die Funktion der ersten Rastmittel 14 im Zusammenhang mit den folgenden Figuren beschrieben werden. Die Kupplung 10, die in Figur 1 gezeigt ist, weist weiterhin ausgehend von dem Gehäuse 11 insbesondere parallel zueinander ausgerichtete Stege 15 auf, wobei die zumindest zwei Stege 15 über eine Querverbindung, die bei diesem Ausführungsbeispiel als zwei Quersteganordnungen 16, 17 ausgebildet sind, miteinander verbunden sind. Auf die Ausgestaltung der Stege 15 und Quersteganordnungen 16, 17 wird ebenfalls bei den folgenden Figuren eingegangen. FIG. 1 shows the three-dimensional view of a coupling 10, which form a plug connection after assembly with a corresponding connector. The coupling 10 has an existing example of plastic housing 11, which may have a protective collar 12 on the cable side. Within the housing 11, a receiving space 13 is provided in which the required for the connector on the part of the clutch 10 contacts arranged in FIG. 1 but for the sake of simplicity are not shown. The shape, the design and the number and arrangement of the contact partners in the receiving space 13 is not the subject of the invention and depending on the operating conditions of the coupling 10 selectable. Furthermore, the coupling 10 has first latching means 14, which are designed as a kind of rocker, to which a plate is attached via a web to the housing 11 of the coupling 10. In a particularly advantageous manner, the locking means 14 are already made with production of the housing 11 of the coupling 10. This can be done for example in a plastic injection molding process. The plate of the first locking means 14 has mutually parallel webs and a recess, which are in connection with the locking elements to be described in the following figures of importance. Likewise, the function of the first locking means 14 will be described in conjunction with the following figures. The coupling 10, which in FIG. 1 is further shown, starting from the housing 11 in particular parallel to each other aligned webs 15, wherein the at least two webs 15 via a cross-connection, which are formed in this embodiment as two transverse web assemblies 16, 17, connected to each other. The design of the webs 15 and crossbar assemblies 16, 17 is also discussed in the following figures.

Figur 2 zeigt die Kupplung 10 gemäß Figur 1 im Schnitt, wobei bezüglich der Gestaltung der Kupplung 10 noch ein Aufnahmeraum für einen Stecker in der Kupplung 10 mit der Bezugsziffer 18 bezeichnet ist. Erfindungsgemäß ist in Figur 2 gezeigt, dass ein Verriegelungselement 20 an den ersten Rastmitteln 14 angeordnet ist. Das separat von dem Gehäuse 11 der Kupplung 10 herzustellende Verriegelungselement 20 wird nach seiner Herstellung auf die ersten Rastmittel 14 aufgesetzt und ist dort in Steckrichtung längs verschiebbar. Zur Realisierung der Doppelverriegelung weist das Verriegelungselement 20 einen speziell geformten Frontbereich 21 auf, der mehrstufig (Stufen 22 und 23) ausgebildet ist. Der Zweck der mehrstufigen Ausgestaltung des Frontbereiches 21 besteht darin, das Verriegelungselement 20 von seiner Vorverraststellung, die hier in Figur 2 dargestellt ist, erst dann in seine Endraststellung bewegen zu können, wenn sich im Aufnahmeraum 18 der Kupplung 10 ein Stecker befindet. Die weitere Funktion des Verriegelungselementes 20 besteht darin, dass, wenn sich im Aufnahmeraum 18 der Kupplung 10 ein Stecker befindet, das Rastmittel 14 zu blockieren, um ein Lösen der Steckverbindung zu verhindern. Das Spiel zwischen Rastnase 25 und Quersteg 161 sowie der Anlagefläche 142 ist derart gestaltet, dass die Ausnehmung 141 ausreichend Platz für einen korresponiderenden Stecker 30 und insbesondere dessen Rastnase 31 gewährleistet. Zur Verhinderung einer Bewegung des Verriegelungselementes 20 von seiner in Figur 2 gezeigten Vorverraststellung in seine Endverraststellung kommt die erste Stufe 22 zur Anlage an einen Quersteg 143 der Rastmittel 14, so dass der Frontbereich 21 zunächst aus seiner gezeigten Position ausgelenkt werden muß, um das Verriegelungselement 20 längs zu verschieben. Um zu verhindern, dass das Verriegelungselement 20 sich von der Kupplung 10 wieder löst, kommt der Frontbereich 21 zur Anlage an einer Anschlagfläche 142 der Rastmittel 14. Durch die Montage des Verriegelungselementes 20 in Vorraststellung schnappt der Frontbereich 21 in die Ausnehmung (Freisparung) 141 formschlüssig ein. Dadurch wird ein Verlieren des Verriegelungselementes 20 verhindert. Ein weiteres Verschieben des Verriegelungselementes 20 in Steckrichtung wird, solange sich kein Stecker im Aufnahmeraum 18 befindet, durch die Abstufung 22 (siehe Figur 3) verhindert. FIG. 2 shows the coupling 10 according to FIG. 1 in section, wherein with respect to the design of the clutch 10 is still a receiving space for a plug in the coupling 10 is designated by the reference numeral 18. According to the invention is in FIG. 2 show that a locking element 20 is arranged on the first locking means 14. The separately produced from the housing 11 of the coupling 10 locking element 20 is placed after its manufacture on the first locking means 14 and is longitudinally displaceable there in the insertion direction. To realize the double locking, the locking element 20 has a specially shaped front region 21, which is formed in multiple stages (steps 22 and 23). The purpose of the multi-stage design of the front portion 21 is to lock the locking element 20 from its pre-locked position, which is shown in FIG FIG. 2 is shown, only to be able to move into its final locked position when in the receiving space 18 of the clutch 10 is a plug. The further function of the locking element 20 is that when in the receiving space 18 of the clutch 10 is a plug to block the locking means 14 to prevent release of the connector. The play between locking lug 25 and cross bar 161 and the contact surface 142 is designed such that the recess 141 ensures sufficient space for a korresponiderenden connector 30 and in particular its locking lug 31. To prevent movement of the locking element 20 of his in FIG. 2 shown Vorverraststellung in its Endverraststellung comes the first stage 22 to rest on a transverse web 143 of the locking means 14, so that the front portion 21 must first be deflected from its position shown in order to move the locking member 20 along. In order to prevent the locking element 20 is released from the clutch 10 again, the front portion 21 comes to rest on a stop surface 142 of the locking means 14. By mounting the locking member 20 in the pre-engaged position of the front portion 21 snaps into the recess (recessed) 141 form fit one. As a result, a loss of the locking element 20 is prevented. A further displacement of the locking element 20 in the insertion direction, as long as there is no plug in the receiving space 18, by the gradation 22 (see FIG. 3 ) prevented.

Figur 3 zeigt die detaillierte Ausgestaltung des Verriegelungselementes 20, welches an den ersten Rastmitteln 14 angeordnet ist. Der Frontbereich 21 des Verriegelungselementes 20 weist eine Abstufung auf, die sich quer zur Steckverbindungsrichtung erstreckt. Hierbei handelt es sich um eine erste Stufe 22 sowie eine zweite Stufe 23, wobei dieser speziell geformte Frontbereich 21 an dem einen Ende einer Lasche 24 angeordnet ist. Diese sich längs erstreckende Lasche 24 hat den Vorteil, dass nach dem Einsetzen des Verriegelungselementes 20 und der entsprechenden Materialwahl, insbesondere aus Kunststoff, eine Auslenkung des Frontbereiches 21 möglich ist. Für die weitere, dauerhafte Festlegung des Verriegelungselementes 20 ist eine Rastnase 25 vorgesehen, der bewirkt, dass das Verriegelungselement 20 auch dann in einer Endverraststellung verbleibt, wenn auf die Steckverbindung rauhe Umgebungsbedingungen, insbesondere Vibrationen und Temperaturschwankungen, wirken. Nuten 26 des Verriegelungselementes 20 sind dazu vorgesehen, dass sie die Platte der ersten Rastmittel 14 zwecks einer Längsführung umgreifen. Gleiches gilt für Ausnehmungen 27, die eine Führung des Verriegelungselementes 20 in Verbindung mit den Stegen auf der Platte der ersten Rastmittel bewirken. Dadurch ist eine Doppelführung gegeben, die eine einfache Längsverschiebung des Verriegelungselementes 20 an den ersten Rastmitteln 14 bewirkt. Alternativ dazu ist es denkbar, nur die Nuten 26 oder nur die Ausnehmungen 27 an dem Führungselement 20 zwecks Führung vorzusehen. Für die leichte Handhabung des Verriegelungselementes 20 weist dieses an dem anderen Ende der Lasche 24 ein Griffteil 28 auf, das hier beispielsweise als Quersteg ausgebildet ist. Die Form des Griffteiles 28 kann insbesondere so gewählt werden, dass eine manuelle Betätigung des Verriegelungselementes 20 ohne Hilfswerkzeuge oder gegebenenfalls mit Hilfswerkzeugen möglich ist. Eine besonders vorteilhafte Ausgestaltung des Verriegelungselementes 20, insbesondere des Griffteiles 28, ist darin zu sehen, dass nach der Herstellung der Kupplung 10 und des Verriegelungselementes 20 das Verriegelungselement 20 bei seinem Hersteller in die Vorverraststellung (siehe Figur 2) gebracht wird und eine derartig, auch mit Kabeln und Kontaktpartnern vorkonfektionierte Kupplung 10 zur weiteren Verwendung ausgeliefert wird. Ebenso ist es denkbar, die Kupplung 10 gemäß Figur 2 vorzubereiten und an einen Kabelkonfektionär, der diese Kupplung 10 mit Kabeln und Kontaktpartnern bestückt, auszuliefern. Bezüglich des in Figur 3 gezeigten Verriegelungselementes 20 ist noch eine ausgehend von der Lasche 24 in Richtung der Ausnehmungen 27 verlaufende Schrägführung 29 zu erwähnen, die das Anordnen des Verriegelungselementes 20 an die ersten Rastmittel 14 vereinfacht. FIG. 3 shows the detailed embodiment of the locking element 20, which is arranged on the first locking means 14. The front portion 21 of the locking member 20 has a step which extends transversely to the connector direction. This is a first stage 22 and a second stage 23, wherein this specially shaped front portion 21 is arranged at one end of a tab 24. This longitudinally extending tab 24 has the advantage that after the insertion of the locking element 20 and the appropriate choice of material, in particular made of plastic, a deflection of the front portion 21 is possible. For the further, permanent fixing of the locking element 20, a latching lug 25 is provided, which causes the locking element 20 also remains in a Endverraststellung when harsh environmental conditions, in particular vibrations and temperature fluctuations act on the connector. Grooves 26 of the locking element 20 are provided so that they engage around the plate of the first locking means 14 for the purpose of a longitudinal guide. The same applies to recesses 27, which cause a guide of the locking element 20 in conjunction with the webs on the plate of the first locking means. As a result, a double guide is provided, which causes a simple longitudinal displacement of the locking element 20 on the first locking means 14. Alternatively, it is conceivable to provide only the grooves 26 or only the recesses 27 on the guide member 20 for guidance. For easy handling of the locking element 20, this has at the other end of the tab 24 on a handle portion 28 which is formed here, for example, as a crossbar. The shape of the handle part 28 can in particular be selected so that a manual actuation of the locking element 20 without auxiliary tools or optionally with auxiliary tools is possible. A particularly advantageous embodiment of the locking element 20, in particular of the handle member 28, is to be seen in that after the production of the coupling 10 and the locking element 20, the locking member 20 at its manufacturer in the Vorverraststellung (see FIG. 2 ) is brought and such, pre-assembled with cables and contact partners clutch 10 is shipped for further use. It is also conceivable, the clutch 10 according to FIG. 2 to prepare and to deliver to a cable manufacturer who equipped this coupling 10 with cables and contact partners. Regarding the in FIG. 3 shown locking element 20 is still a starting from the tab 24 in the direction of the recesses 27 extending oblique guide 29 to be mentioned, which simplifies the placement of the locking element 20 to the first locking means 14.

Bisher war zu Figur 3 beschrieben und in Figur 3 gezeigt, dass das Verriegelungselement 20 derart ausgestaltet ist, dass es an den Rastmitteln 14, genauer an der Platte, die sich an dem Gehäuse 11 befindet, geführt wird. Dies ist einerseits vorteilhaft, weil damit eine präzise Führung des Verriegelungselementes 20 beim Einsetzen in Bezug zu der Kupplung 10 (oder alternativ des Steckers 30) gegeben ist. Eine solche Führung an den Rastmitteln 14 kann vorhanden sein (wie in Figur 3 dargestellt), kann alternativ aber auch weggelassen werden, so dass das Verriegelungselement 20 lediglich mit seinen Außenkonturen führend in die Steganordnung 15, 16, 17 gelagert ist. Damit können dann die Nuten 26 und/oder die Schrägführung 29 des Verriegelungselementes 20 (s. Figur 3) entfallen. Eine Führung des Verriegelungselementes 20 erfolgt dann nur noch entweder über die Lasche 24 und/oder die Außenflächen des Griffteiles 28 beim Einsetzen des Verriegelungselementes 20 in den durch das Gehäuse 11 und die Steganordnung 15, 16, 17 gebildeten Raum.So far was too FIG. 3 described and in FIG. 3 shown that the locking element 20 is designed such that it is guided on the locking means 14, more precisely on the plate, which is located on the housing 11. On the one hand, this is advantageous because it provides precise guidance of the locking element 20 when it is inserted with respect to the coupling 10 (or alternatively the plug 30). Such a guide on the locking means 14 may be present (as in FIG. 3 shown), but may alternatively be omitted, so that the locking element 20 is guided only with its outer contours leader in the web assembly 15, 16, 17. Thus, then the grooves 26 and / or the inclined guide 29 of the locking element 20 (s. FIG. 3 ) accounted for. A guide of the locking element 20 then takes place only either via the tab 24 and / or the outer surfaces of the handle member 28 upon insertion of the locking element 20 in the space formed by the housing 11 and the web assembly 15, 16, 17 space.

Figur 4 zeigt im Schnitt die Kupplung 10, wobei in den Aufnahmeraum 18 nun ein korrespondierender Stecker 30 eingesetzt worden ist, wobei auch hier auf die Darstellung der an sich vorhandenen Kontaktpartner und Kabel verzichtet worden ist. Der Stecker 30 weist auf seiner Umfangsfläche die Rastnase 31 auf, welche in die Ausnehmung 141 gelangen kann. Das Einsetzen des Steckers 30 und das Vorhandensein der Rastnase 31 bewirkt zunächst eine Primärverriegelung, indem die Rastnase 31 zur Anlage kommt mit den korrespondierenden Flächen der Ausnehmung 141 der ersten Rastmittel 14. Hiervon unberührt bleibt zunächst der Frontbereich 21 des Verriegelungselementes 20, der sich noch in seiner ursprünglichen Position, wie sie in Figur 2 dargestellt ist, befindet. Es erfolgt zunächst lediglich die Primärverriegelung zwischen Kupplung 10 und Stecker 30 durch die Rastnase 31 an dem Stecker 30. FIG. 4 shows in section the coupling 10, wherein in the receiving space 18 now has a corresponding connector 30 has been used, which has been omitted here on the representation of the existing contact partners and cable. The plug 30 has on its peripheral surface on the locking lug 31, which can get into the recess 141. The insertion of the plug 30 and the presence of the locking lug 31 first causes a primary locking by the latching nose 31 comes into abutment with the corresponding surfaces of the recess 141 of the first locking means 14. This remains unaffected initially the front portion 21 of the locking element 20, which is still in his original position, as in FIG. 2 is shown is located. Initially, only the primary locking between the coupling 10 and the plug 30 takes place through the latching nose 31 on the plug 30.

In dieser Schnittdarstellung der Kupplung 10 ist auch eine mögliche, vereinfachte Ausgestaltung der Quersteganordnung 16 zu erkennen, die nämlich aus zwei weitestgehend parallel zueinander verlaufenden Querstegen 161, 162 besteht.In this sectional view of the coupling 10 is also a possible, simplified embodiment of the crosspiece assembly 16 can be seen, which consists of two largely parallel to each other transverse webs 161, 162.

Bezüglich der in Figur 4 gezeigten Quersteganordnung 16 handelt es sich (entgegen der in den Figuren 1 und 6 gezeigten Quersteganordnung) um lediglich zwei parallel zueinander verlaufende Querstege 161, 162, die zusammen eine Ausnehmung 32 bilden. Dabei sind Geometrie und Material des Quersteges 162 so gewählt, dass beim Bewegen des Verriegelungselementes 20 von der Vorraststellung in die Endraststellung eine kurzzeitige Verformung (Nachgiebigkeit) des Quersteges 162 zulässig ist, wenn die Rastnase 25 in Richtung der Ausnehmung 32 bewegt wird. Die umgekehrte Vorgehensweise ist auch denkbar, dass nämlich der von der Rastnase 25 zu überwindende zweite Quersteg 162 starr und stabil ausgebildet ist und beim Bewegen des Verriegelungselementes 20 von der Vorraststellung in die Endraststellung sich die Form der Rastnase 25 kurzzeitig verändert (nachgibt beim Überwinden des zweiten Quersteges 162). Das gerade Beschriebene betrifft eine einfache Ausgestaltung der Quersteganordnung 16, mit der ermöglicht wird, das Verriegelungselement 20 nach dem Bewegen von seiner Vorraststellung in seiner Endraststellung in der letztgenannten Stellung zuverlässig festzusetzen, wozu die Rastnase 25 lediglich den Quersteg 162 überwinden muß. Eine alternative Ausgestaltung ist dagegen in Figur 1 schon angedeutet und im Detail in Figur 6 gezeigt und dort beschrieben. Anstelle von zwei Querstegen kann die Steganordnung 16 auch eine ebene Fläche sein, die eine Vertiefung oder die Ausnehmung 32 aufweist, in die die Rastnase 25 eingreifen kann.Regarding the in FIG. 4 shown crosspiece assembly 16 is (contrary to the in the FIGS. 1 and 6 shown transverse web assembly) by only two mutually parallel transverse webs 161, 162, which together form a recess 32. In this case, the geometry and material of the transverse web 162 are selected so that when moving the locking element 20 from the pre-locking position into the final locked position, a short-term deformation (yielding) of the transverse web 162 is permitted if the Latch 25 is moved in the direction of the recess 32. The reverse approach is also conceivable, namely that of the locking lug 25 to be overcome second cross bar 162 is rigid and stable and when moving the locking element 20 from the pre-locking position in the final locked position, the shape of the latch 25 changes briefly (yields when overcoming the second Cross bar 162). The just described relates to a simple embodiment of the crosspiece assembly 16, which allows the locking element 20 to be fixed reliably after moving from its pre-locking position in its final locked position in the last-mentioned position, for which purpose the detent nose 25 only has to overcome the crosspiece 162. An alternative embodiment, however, is in FIG. 1 already hinted at and in detail in FIG. 6 shown and described there. Instead of two transverse webs, the web assembly 16 may also be a flat surface having a recess or the recess 32 into which the locking lug 25 can engage.

Figur 5 zeigt den Schnitt durch die Kupplung 10 mit eingesetztem Stecker gemäß Figur 4, wobei das Verriegelungselement 20 von seiner in Figur 4 gezeigten Vorverraststellung in seine Endverraststellung (durch Längsverschiebung bei Betrachtung der Figur 5 von rechts nach links) gebracht worden ist. Diese Längsverschiebung des Verriegelungselementes 20 bewirkt, dass die zweite Stufe 23 des Frontbereiches 21 über die ansteigende Rastnase 31 des Steckers 30 eine Anhebung der Lasche 24 bewirkt, so dass der Frontbereich 21 in eine Ausnehmung 33 des Quersteges 17 gelangen kann. Dabei ist die Ausnehmung 33 den Außenabmessungen des Frontbereiches 21 angepaßt, so dass dieser in der Ausnehmung 33 formschlüssig festgelegt wird. Dadurch wird bewirkt, dass die durch die ersten Rastmittel 14 bewirkte Primärverriegelung nicht mehr gelöst werden kann, weil die Platte der ersten Rastmittel 14 in ihrer Lage durch den Frontbereich 21 des Verriegelungselementes 20 festgelegt ist. Weiterhin ist zur Verhinderung, dass sich das Verriegelungselement 20 aus seiner in Figur 5 gezeigten Endverraststellung herausbewegt, vorgesehen, dass das Verriegelungselement 20 die Rastnase 25 aufweist, mit der das Verriegelungselement 20 an der Kupplung 10, insbesondere in die Ausnehmung 32 zwischen den Querstegen 161, 162, festlegbar ist. Nach dem Verschieben des Verriegelungselementes 20 von der Vorverraststellung in die Endverraststellung, wobei der Quersteg 162 zum einfachen Überwinden der Anlagekräfte eine Schrägführung für die Rastnase 25 aufweist, kommt die Rastnase 25 innerhalb der Ausnehmung 32 formschlüssig an dieser zur Anlage und wird dort zuverlässig festgesetzt. Damit wird wirksam verhindert, dass sich das Verriegelungselement 20 bei noch so rauhen Umgebungsbedingungen aus seiner Endverraststellung heraus bewegen kann. FIG. 5 shows the section through the coupling 10 with inserted plug according to FIG. 4 , wherein the locking element 20 of his in FIG. 4 shown Vorverraststellung in its Endverraststellung (by longitudinal displacement in viewing the FIG. 5 from right to left) has been brought. This longitudinal displacement of the locking element 20 causes the second stage 23 of the front portion 21 via the rising latch 31 of the plug 30 causes an increase in the tab 24, so that the front portion 21 can enter into a recess 33 of the transverse web 17. In this case, the recess 33 is adapted to the outer dimensions of the front region 21, so that it is fixed in a form-fitting manner in the recess 33. This causes that caused by the first locking means 14 primary lock can not be solved because the plate of the first locking means 14 is fixed in position by the front portion 21 of the locking element 20. Furthermore, to prevent that the locking element 20 from its in FIG. 5 shown moved out, provided that the locking element 20 has the latching lug 25, with which the locking element 20 on the coupling 10, in particular in the recess 32 between the transverse webs 161, 162, can be fixed. After moving the locking element 20 of the Vorverraststellung in the Endverraststellung, wherein the crossbar 162 for easy overcoming the contact forces has a skewed guide for the locking lug 25, the locking lug 25 comes within the recess 32 form-fitting to this system and is reliably fixed there. This effectively prevents the locking element 20 can move out of its Endverraststellung even under harsh environmental conditions.

Insgesamt hat das erfindungsgemäße Verriegelungselement 20, seine Formgebung, seine Materialwahl und insbesondere seine Anordnung an den ersten Rastmitteln den Vorteil, dass es ohne weiteres an den schon vorhandenen ersten Rastmitteln nachgerüstet werden kann, aufgrund der Formgebung und Materialwahl ohne großen Kraftaufwand von der Vorverraststellung in die Endverraststellung gebracht und aufgrund des in Zusammenhang mit der Ausführung gemäß Figur 5 geschilderten Formschlusses in dieser Endverraststellung gehalten wird.Overall, the locking element 20 according to the invention, its shape, its choice of material and in particular its arrangement on the first locking means has the advantage that it can be easily retrofitted to the already existing first locking means, due to the shape and choice of material without much effort from the Vorverraststellung in the Final Verstellung brought and because of in connection with the execution according to FIG. 5 described positive connection is held in this Endverraststellung.

Figur 6 zeigt abschließend die aus Kupplung 10 und Stecker 30 bestehende Steckverbindung, wobei es sich bei dem Stecker 30 auch um einen Gerätestecker handeln kann. Deutlich erkennbar ist die Doppelverriegelung der Steckverbindung mittels des erfindungsgemäßen Verriegelungselementes 20, die - wie schon beschrieben - äußerst wirksam ist und darüber hinaus noch kompakt baut, da sie in Längsrichtung nicht über die Außenabmessungen des Gehäuses der Kupplung 10 übersteht. Ein weiterer Vorteil besteht darin, dass das erfindungsgemäße Verriegelungselement 20 für beliebige Kupplungen (gleiches gilt auch für Stecker) eingesetzt werden kann, so dass der Einsatz des Verriegelungselementes unabhängig ist von der Polzahl der Kupplung bzw. des Steckers. Ebenso ist das Verriegelungselement unabhängig von der Art der verwendeten Kabel (z. B. Rundkabel, Flachkabel oder dergleichen) sowie der eingesetzten Kontaktpartner. Die in Figur 6 gezeigte Kupplung 10 ist darüber hinaus auch ohne den Einsatz des Verriegelungselementes 20 zu verwenden, wobei dann nur eine unter bestimmten Gegebenheiten ausreichende Primärverriegelung (einzige Verriegelung) der Steckverbindung gegeben ist. FIG. 6 finally shows the connector 10 and connector 30 existing plug connection, wherein it can be at the plug 30 is also a device connector. Clearly recognizable is the double locking of the connector by means of the locking element 20 according to the invention, which - as already described - is extremely effective and moreover still compact, since it does not protrude beyond the outer dimensions of the housing of the clutch 10 in the longitudinal direction. Another advantage is that the locking element 20 according to the invention for any couplings (the same applies to connectors) can be used, so that the use of the locking element is independent of the number of poles of the coupling or the plug. Likewise, the locking element is independent of the type of cable used (eg round cable, flat cable or the like) and the contact partners used. In the FIG. 6 shown coupling 10 is also to use without the use of the locking element 20, in which case only one under certain circumstances sufficient primary lock (single lock) is given to the connector.

Bei Betrachtung der Figur 6 ist eine alternativ denkbare Ausgestaltung der Quersteganordnung 16 gezeigt, bei der wiederum ausgehend von den beiden in etwa parallel verlaufenden Stegen 15 quer dazu angeordnete Querstege 161, 162 vorhanden sind. Bei dieser in Figur 6 (und auch schon in Figur 1) gezeigten Quersteganordnung 16 ist an dem ersten Quersteg 161, der starr ausgebildet ist, eine Lasche 163 angeordnet, die einen etwa quadratischen oder rechteckförmigen Verlauf hat. Diese Lasche 163 bildet zusammen mit dem ersten Quersteg 161 die Ausnehmung 32, die später die Rastnase 25 des Verriegelungselementes 20 in seiner Endraststellung aufnimmt. Aufgrund dieser Geometrie ist es möglich, dass mit relativ geringen Kräften die Rastnase 25 bei ihrer Bewegung von der Vorraststellung in die Endraststellung die Lasche 163, die aufgrund ihrer Geometrie und Materialwahl elastisch verformbar ist, überwindet und in die Ausnehmung 32 eintauchen kann. Ist dies erfolgt, wird die Rastnase 25 durch die Formgebung der Lasche 163 daran gehindert, sich wieder in Richtung der Vorraststellung zu bewegen. Andererseits ist es möglich, beispielsweise unter Einsatz eines Werkzeuges, die Lasche 163 anzuheben und das Verriegelungselement 20 in die Vorraststellung zu bewegen, um Kupplung 10 und Stecker 30 voneinander trennen zu können. Bei dieser in Figur 6 gezeigten Quersteganordnung 16 weist darüber hinaus der zweite Quersteg 162 noch ein Fenster 164 auf, über welches ermöglicht wird, dass das Verriegelungselement 20 von der Vorraststellung in die Endraststellung bewegt werden kann und dabei die Rastnase 25 in die Ausnehmung 32 gelangen kann. Alternativen zu dieser in Figur 6 gezeigten Quersteganordnung 16 sind beispielsweise, dass die Lasche 163 nicht an dem ersten Quersteg 161, sondern an dem zweiten Quersteg 162 angeordnet ist. Ebenso besteht eine Alternative darin, dass nicht eine Lasche 163 (wie zum Beispiel dargestellt in etwa in U-Form) an dem ersten Quersteg 161 angeordnet ist, sondern parallel zwischen den beiden Querstegen 161, 162 ein weiterer Quersteg vorhanden ist. Ebenso ist eine Ausgestaltung zur Lagefixierung des Verriegelungselementes 20 in seiner Endraststellung denkbar, bei der das Verriegelungselement 20 analog eine Quersteganordnung aufweist und analog eine Rastnase an einer Steganordnung zwischen den beiden Stegen 15 vorhanden ist. Damit wird also die in Figur 6 gezeigte Quersteganordnung 16 und die Rastnase 25 an dem Verriegelungselement 20 "umgedreht" angewendet.Looking at the FIG. 6 an alternatively conceivable embodiment of the crosspiece assembly 16 is shown, in which, in turn, starting from the two approximately parallel webs 15 transversely arranged transverse webs 161, 162 are present. At this in FIG. 6 (and already in FIG. 1 ) shown cross bar assembly 16 is on the first cross bar 161, which is rigidly formed, a tab 163 is arranged, which has an approximately square or rectangular shape. This tab 163, together with the first cross bar 161, the recess 32, which later receives the locking lug 25 of the locking element 20 in its final locked position. Due to this geometry, it is possible that with relatively small forces, the locking lug 25 in its movement from the pre-locking position into the final locked position, the tab 163, which is elastically deformable due to their geometry and choice of material, overcomes and in the Recess 32 can dip. If this is done, the latching lug 25 is prevented by the shape of the tab 163 from moving back toward the pre-locking position. On the other hand, it is possible, for example using a tool, to raise the tab 163 and to move the locking element 20 into the pre-locked position in order to be able to separate the coupling 10 and the connector 30 from one another. At this in FIG. 6 In addition, the second transverse web 162 still has a window 164, via which it is made possible that the locking element 20 can be moved from the pre-locking position into the final locked position and thereby the locking nose 25 can enter the recess 32. Alternatives to this in FIG. 6 shown crosspiece assembly 16 are, for example, that the tab 163 is not disposed on the first cross bar 161, but on the second cross bar 162. Likewise, an alternative is that not a tab 163 (such as shown in approximately U-shape) is disposed on the first crossbar 161, but parallel between the two transverse webs 161, 162, a further crosspiece is present. Likewise, an embodiment for fixing the position of the locking element 20 in its final detent position is conceivable in which the locking element 20 analog has a transverse web arrangement and, analogously, a latching lug is provided on a web arrangement between the two webs 15. So that is the in FIG. 6 shown transverse web assembly 16 and the locking lug 25 on the locking element 20 "reversed" applied.

Die Figuren 7 bis 9 zeigen Schnitte durch die Kupplung 10, und zwar analog zu der Ausgestaltung, wie sie in Figur 2 dargestellt ist, sowie die Funktion des Verriegelungselementes 20 vor und nach dem Einsetzen des Steckers 30 in die Kupplung 10. In Figur 7 ist die Kupplung 10 gezeigt, bei der das Verriegelungselement 20 (beispielsweise ausgebildet wie in Figur 3 gezeigt, also mit Führungsmitteln, oder ausgebildet ohne Mittel zu seiner Führung an den Rastmitteln 14), wobei erkennbar ist, dass das Verriegelungselement 20 mit seinem Frontbereich 21 in der Ausnehmung 141 befindet. Durch diese Ausgestaltung wird bewirkt, dass das Verriegelungselement 20 in der gezeigten Position definiert festgelegt ist. Denn es kann sich bei Betrachtung der Figur 7 nicht weiter nach links verschieben, da die erste Stufe 22 an dem Quersteg 143 anliegt. Es kann aber auch nicht nach rechts bewegt werden, da dann die zweite Stufe 23 an der Anschlagfläche 142 der Rastmittel 14 zur Anlage kommen würde, was eine weitere Verschiebung nach rechts verhindert. Die in Figur 7 gezeigte Kupplung 10 mit ihrem Verriegelungselement 20 zeigt also einen vormontierten Zustand, bei dem der Frontbereich 21 des Verriegelungselementes 20 in einer ersten Ebene E1 liegt.The FIGS. 7 to 9 show sections through the coupling 10, and analogous to the embodiment, as in FIG. 2 is shown, as well as the function of the locking element 20 before and after insertion of the plug 30 in the coupling 10. In FIG. 7 For example, the coupling 10 is shown in which the locking element 20 (formed, for example, as in FIG FIG. 3 shown, so with guide means, or formed without means for its guidance on the locking means 14), wherein it can be seen that the locking element 20 is located with its front portion 21 in the recess 141. This configuration causes the locking element 20 is defined defined in the position shown. Because it can look at the FIG. 7 do not move further to the left, since the first step 22 rests against the transverse web 143. But it can not be moved to the right, because then the second stage 23 would come to rest on the stop surface 142 of the locking means 14, which prevents further displacement to the right. In the FIG. 7 Coupling 10 shown with its locking element 20 thus shows a preassembled state in which the front portion 21 of the locking element 20 is located in a first plane E1.

Figur 8 zeigt, dass der Stecker 30 mit seiner zumindest einen Rastnase 31 in die Kupplung 10 eingesetzt worden ist. Die schräge Ausführung der Rastnase 31 bewirkt beim Einsetzen des Steckers 30 in die Kupplung 10, dass der Frontbereich 21 des Verriegelungselementes 20 in eine weitere Ebene E2 angehoben wird, ohne dass sich dabei das Verriegelungselement 20 ansonsten weiterbewegt. Diese Anhebung des Frontbereiches 21 wird dadurch bewirkt, dass die zweite Stufe 23 über die Schräge der Rastnase 31 nach oben gleiten kann, bis die in Figur 8 gezeigte Position erreicht wird. Damit wird auch gleichzeitig die erste Stufe 22 auf ein solches Niveau über den Quersteg 143 angehoben, dass diese erste Stufe 22 nicht mehr an dem Quersteg 143 anliegt. Dabei ist, genauso wie in Figur 7, die Ausnehmung 33 so gewählt, dass sich der betreffende Teil des Frontbereiches 21 dort frei bewegen kann. FIG. 8 shows that the plug 30 has been inserted with its at least one latching nose 31 in the coupling 10. The oblique design of the locking lug 31 causes when inserting the plug 30 into the coupling 10, that the front portion 21 of the locking member 20 is raised in a further plane E2, without causing the locking member 20 otherwise moves. This raising of the front portion 21 is effected by the second stage 23 can slide over the slope of the locking lug 31 upwards until the in FIG. 8 shown position is reached. Thus, at the same time the first stage 22 is raised to such a level on the crossbar 143, that this first stage 22 is no longer applied to the crossbar 143. It is, as well as in FIG. 7 , the recess 33 is selected so that the relevant part of the front region 21 can move freely there.

Figur 9 schließlich zeigt die Endposition des Verriegelungselementes 20 an der Kupplung 10, die dadurch erreicht wird, dass das Verriegelungselement 20 aus seiner Position, die in Figur 8 dargestellt ist, weiter nach links verschoben wird, um die in Figur 9 dargestellte Endposition zu erreichen. Dieses Verschieben wird dadurch ermöglicht, dass die erste Stufe 22 auf ein solches Niveau angehoben wurde, dass sie über den Quersteg 143 gleiten kann. Dabei wird die Verschiebung des Verriegelungselementes 20 über die Außenkontur der Rastnase 31 des Steckers 30 hinweg aber nur soweit zugelassen, bis die zweite Stufe 23 selber an dem Quersteg 143 zur Anlage kommt. Wenn das der Fall ist, ist eine weitere Verschiebung des Verriegelungselementes 20 nach links (bei Betrachtung der Figur 9) nicht mehr möglich. Eine Verschiebung des Verriegelungselementes 20 nach rechts wird in dieser Endposition durch die Rastnase 25 verhindert, die sich nun in der Ausnehmung 32 befindet und wegen der Anlage an dem zweiten Quersteg 162 nicht mehr zurück kann. Somit nimmt das Verriegelungselement 20 eine definierte Vorverraststellung ein (s. Figur 7), von der es aus nur in die Endverraststellung (s. Figur 9) gebracht werden kann, wenn der Stecker 30 korrekt, das heißt vollständig in die Kupplung 10 eingesetzt worden ist. Sollte zum Beispiel der Stecker 30 nur zur Hälfte in die Kupplung 10 eingesetzt worden sein, würde die Rastnase 31 nicht die Auslenkung des Frontbereiches 21 von der ersten Ebene E1 in die zweite Ebene E2 bewirken, so dass das Verriegelungselement 20 nicht von seiner Vorverraststellung (Figur 7) in seine Endverraststellung (Figur 9) gebracht werden kann. Denn durch das Fehlen des Vorhandenseins der Rastnase 31 des Steckers 30 wäre der zu Figur 8 beschriebene Bewegungsablauf nicht durchführbar. Hier ist auch erkennbar, dass es von besonderem Vorteil ist, dass der Frontbereich 21 des Verriegelungselementes 20 nur einmal von der ersten Ebene E1 in die zweite Ebene E2 ausgelenkt werden muß, so dass keine weiteren Kräfte mehr erforderlich sind, um den Frontbereich 21 in der Endverraststellung wieder in eine weitere Ebene oder in die erste Ebene zurück zu bewegen. FIG. 9 Finally, the end position of the locking element 20 on the coupling 10, which is achieved in that the locking element 20 from its position, the in FIG. 8 is shown, is moved further to the left to the in FIG. 9 reach the end position shown. This displacement is made possible by the first stage 22 has been raised to such a level that it can slide over the transverse web 143. The displacement of the locking element 20 over the outer contour of the locking lug 31 of the plug 30 away but only so far allowed until the second stage 23 itself comes to the crossbar 143 to the plant. If this is the case, a further shift of the locking element 20 to the left (viewing the FIG. 9 ) not possible anymore. A displacement of the locking element 20 to the right is prevented in this end position by the latching lug 25, which is now in the recess 32 and because of the system on the second cross bar 162 can not go back. Thus, the locking element 20 assumes a defined Vorverraststellung (s. FIG. 7 ), from which it only in the Endverraststellung (s. FIG. 9 ) can be brought when the plug 30 is correct, that is, has been fully inserted into the coupling 10. For example, if only half of the connector 30 has been inserted into the coupling 10, the detent 31 would not cause the front portion 21 to deflect from the first plane E1 to the second plane E2, so that the locking member 20 will not move from its pre-locked position (FIG. FIG. 7 ) in its Endverraststellung ( FIG. 9 ) can be brought. Because by the absence of the presence of the locking lug 31 of the plug 30 would be to FIG. 8 described movement sequence not feasible. It can also be seen here that it is of particular advantage that the front region 21 of the locking element 20 only has to be deflected once from the first plane E1 into the second plane E2, so that no further More forces are required to move the front portion 21 in the Endverraststellung back to another level or in the first plane back.

Die erfindungsgemäß mit dem Verriegelungselement ausgerüstete Kupplung bzw. analog ein Stecker ist für Steckverbindungen einsetzbar ohne Beschränkung auf das Einsatzgebiet dieser Steckverbindung, wobei in besonders vorteilhafter Weise eine Anwendung in der Fahrzeugtechnik gegeben ist, da es hier vor allen Dingen auf die dauerhafte Verbindung zwischen Kupplung und Stecker unter Berücksichtigung der Einsatzbedingungen (Vibrationen im Fahrzeug, starke Temperaturwechsel z. B. im Motorraum des Fahrzeuges und dergleichen) ankommt. In diesem Zusammenhang ist noch der Vorteil des erfindunsgemäßen Verriegelungselementes 20 zu nennen, dass aufgrund seiner Formgebung und Materialwahl beim Verschieben von der Vorverraststellung in die Endverraststellung ein "Klickgeräusch" erzeugt, so dass dadurch für den Monteur, der Kupplung und Stecker zusammensetzt, eine Sicherheit gegeben ist, dass die Steckverbindung auch vollständig zusammengesteckt worden ist, da gerade in der Fahrzeugtechnik eine nicht vollständig zusammengesteckte Steckverbindung (durch die keine oder nur eine unzuverlässige Kontaktierung gegeben ist) nachteilige Auswirkungen auf die Funktionstüchtigkeit des Fahrzeuges, insbesondere unter Sicherheitsaspekten, hat.The present invention equipped with the locking element coupling or analog plug is used for connectors without limitation to the field of application of this connector, which is given in a particularly advantageous manner, an application in vehicle technology, since it is above all the permanent connection between the clutch and Plug in consideration of the conditions of use (vibrations in the vehicle, strong temperature changes z., In the engine compartment of the vehicle and the like) arrives. In this context, the advantage of erfindunsgemäßen locking element 20 is yet to mention that due to its shape and choice of material when moving from the Vorverraststellung generated in the Endverraststellung a "click", so that it assists for the fitter, the coupling and plug, a security is that the connector has also been completely mated, since just in the automotive industry, a not fully mated connector (through which no or only an unreliable contact is given) adverse effects on the functionality of the vehicle, especially in safety aspects, has.

Aufgrund der heutzutage kompakten Bauart im Fahrzeug, insbesondere im Motorraum, ist auch eine versehentliche Betätigung der Rastmittel durch die Fertigungsmitarbeiter während der Montage anderer Komponenten möglich.Due to the now compact design in the vehicle, especially in the engine compartment, an accidental operation of the locking means by the manufacturing staff during assembly of other components is possible.
