Description
Die vorliegende Erfindung betrifft einen Steckverbinder nach dem Oberbegriff des Patentanspruchs 1. Ein gattungsgemäßer Steckverbinder ist aus der EP-A-1 207 591 bekannt.Solche Steckverbinder finden hauptsächlich Anwendung in Airbag-Zündsystemen.The present invention relates to a connector according to the Preamble of claim 1. A generic connector is from EP-A-1 207 591. Such connectors find mainly used in airbag ignition systems.
An die Zuverlässigkeit solcher Steckverbinder und der mit ihnen hergestellten Steckverbindungen werden höchste Anforderungen gestellt. Dies einerseits hinsichtlich ihrer Zuverlässigkeit über einen langen Zeitraum und andererseits hinsichtlich des Vermeidens undefinierter Spannungszustände beim Herstellen der Steckverbindung am Zünder. Es muß zum Beispiel gewährleistet sein, dass der Bedienungsperson eindeutig klar ist, dass der Steckverbinder richtig in seiner Endposition im Gegenstecker sitzt, was herkömmlicherweise durch eine Verrastung gewährleistet wird und andererseits muß gewährleistet sein, dass diese Endstellung während der Betriebszeit und insbesondere bei Reparaturarbeiten am Kraftfahrzeug nicht unbeabsichtigt verlassen wird. Dies erreicht man durch eine Sekundärverriegelung, d.h. der Verriegelung von Rastarmen in ihrer verrasteten Stelle, so dass eine Steckverbindung nicht mehr unbeabsichtigt gelöst werden kann.To the reliability of such connectors and with them manufactured connectors are made highest demands. This on the one hand in terms of their reliability over a long period and on the other hand with regard to the avoidance of undefined Voltage conditions when establishing the connector on the igniter. It For example, it must be ensured that the operator is unique It is clear that the connector is correctly in its final position in the Mating connector sits, which is traditionally by a catch on the other hand, it must be ensured that End position during the operating time and in particular at Repair work on the vehicle is not left unintentionally. This is achieved by secondary locking, i. the lock by latching arms in their latched position, leaving a plug connection can not be solved unintentionally.
Bekannte Steckverbinder für Airbag-Zündsysteme, wie beispielsweise aus der DE 10025 295 A1 der Patentanmelderin bekannt, verwenden Sekundärverriegelungen, die erst dann aktiviert werden können, wenn der Steckverbinder bereits in den entsprechenden Gegenstecker eingesteckt ist. D.h., in der Montagestellung befindet sich die Sekundärverriegelung in einer Zwischenstellung verrastet, aus der er nach Herstellung der Steckverbindung mit dem Gegenstecker in seine Endstellung verbracht wird. Der Steckverbinder wird also mit einer Sekundärverriegelung in einer Zwischenstellung angeliefert, wobei es bei der Anlieferung oder bei der Handhabung des Steckverbinders passieren kann, dass die Sekundärverriegelung unbeabsichtigterweise sich bereits in ihrer Endstellung befindet, wenn die Steckverbindung hergestellt werden soll, wodurch letzteres jedoch verhindert wird. Die Sekundärverriegelung wieder zu lösen bedeutet zusätzlichen Zeitaufwand und macht eine gegebenenfalls automatisch erfolgende Montage unmöglich. Außerdem kann nach erfolgter Steckverbindung vergessen werden, auch die Sekundärverriegelung zu verrasten, so dass nicht mit Sicherheit ausgeschlossen werden kann, dass die Steckverbindung weiterhin lösbar ist.Known connector for airbag ignition systems, such as DE 10025 295 A1 of the patent applicant, use Secondary locks, which can only be activated when the Connector is already plugged into the corresponding mating connector. That is, in the mounting position, the secondary latch is in one Intermediate position latched, from which he after making the Plug connection is spent with the mating connector in its end position. The connector is thus with a secondary lock in one Intermediate position delivered, whereby it at the delivery or at the Handling the connector can happen that the Secondary lock inadvertently already in their End position is when the connector is to be made, whereby the latter is prevented, however. The secondary lock again solving means extra time and makes one if necessary automatic assembly impossible. In addition, after successful Plug connection are forgotten, also the secondary lock too latch so that can not be ruled out with certainty that the connector is still solvable.
Die EP-A-1 207 591 beschreibt einen Steckverbinder, insbesondere für Airbag-Zündsysteme, mit in Steckrichtung angeordneten Verriegelungszungen zum Verrasten des Steckverbinders in einem Gegenstecker und mit einer Sekundärverriegelung, die nach erfolgter (Primär-) Verriegelung einen Spalt zwischen den Verriegelungszungen und dem Steckverbindergehäuse auffüllt, um ein Lösen der Verriegelung zu verhindern. Die Sekundärverriegelung kann erst nach der Primärverriegelung stattfinden und erfordert daher einen zweiten Arbeitsgang, um den Einsteckprozess abzuschließen.EP-A-1 207 591 describes a connector, in particular for Airbag ignition systems, with arranged in the direction of insertion Locking tongues for locking the connector in one Mating connector and with a secondary lock, which after successful (Primary) locking a gap between the locking tabs and fills the connector housing to release the lock to prevent. The secondary lock can only after the Primary lock take place and therefore requires a second Operation to complete the insertion process.
Der Erfindung liegt daher die Aufgabe zugrunde, einen gattungsgemäßen Steckverbinder dahingehend zu verbessern, dass eine Sekundärverriegelung nicht mehr separat nach erfolgter Verbindung mit einem Gegenstecker hergestellt werden muß, sondern bereits gleichzeitig beim Ineinanderstecken von Steckverbinder und Gegenstecker erfolgt.The invention is therefore based on the object, a generic Improve connectors in that a secondary lock no longer separately after connection with a mating connector must be made, but already at the same time nesting from connector and mating connector.
Diese Aufgabe wird anspruchsgemäß gelöst. This task is solved according to the claims.
In den Unteransprüchen sind bevorzugte Ausgestaltungen des erfindungsgemäßen Steckverbinders gekennzeichnet. Das Prinzip der vorliegenden Erfindung besteht darin, daß die radiale Verschwenkbewegung einer Verriegelungszunge beim Einrasten unter einer entsprechenden Schulter im Gegenstecker zur Steuerung der Bewegung von Sekundärverriegelungszungen verwendet wird, die während des Einsteckvorgangs vorgespannt werden, so daß ihnen beim Einrasten der Verriegelungszungen der Weg freigegeben wird, sich mit ihren freien Enden hinter die Verriegelungszungen zu bewegen, um damit ein Lösen der Verriegelungszungen unmöglich zu machen.In the dependent claims are preferred embodiments of marked connector according to the invention. The principle of present invention is that the radial pivoting movement a locking tongue when snapping under a corresponding Shoulder in mating connector to control the movement of Secondary locking tongues is used during the Be pre-tensioned insertion, so that when snapping the Locking tongues the way is released, with their free ends to move behind the locking tabs, thereby releasing the Locking tongues impossible to make.

Die Figur 4a und 4b zeigen den Steckvorgang des Steckverbinders 1 in den
Gegenstecker 3. Von dem Gegenstecker 3 ist nur ein Inlet gezeigt, das im
Bereich der Verriegelungszunge 2 aufgeschnitten ist, um den Steckerteil des
Steckverbinders 1 zu zeigen. Figur 4a zeigt den Steckverbinder 1 soweit in
den Gegenstecker 3 eingesteckt, daß die Keile 4e, 4f auf dem oberen Rand
des Einführungsschlitzes 7 im Gegenstecker 3 aufliegen. In dieser Stellung
stößt gleichzeitig die Rastnase 2c auf eine in dieser Abbildung nicht gezeigte
Rastschulter am Gegenstecker 3, so daß bei dem in Figur 4b gezeigten
weiteren Hereindrücken des Steckverbinders 1 in den Gegenstecker 3 sich
die Verriegelungszunge 2 beim Überwinden der Schulter in Richtung
Steckachse verbiegt.Figures 4a and 4b show the plugging operation of the connector 1 in the
Dieses Verbiegen der Verriegelungszunge 2 führt dazu, daß der Vorsprung
2D (siehe Figur 5) in Richtung Steckachse bewegt wird und somit den freien
Enden 4c, 4d der Sekundärverriegelungszungen 4a, 4b eine Anlagefläche
bietet. Beim weiteren Hereindrücken des Steckverbinders 1 verbiegen sich
die mittleren Bereiche der Sekundäreverriegelungszungen 4a, 4b auf Grund
des Kontaktes der Keile 4e, 4f mit den Schmalseiten des
Einführungsschlitzes 7 soweit, daß diese mittleren Bereiche sich in den

Gegenstecker 3 eingesteckt, springt die Verriegelungszunge 2 wieder in ihre
Ausgangsstellung zurück, nachdem sie die (nicht gezeigte) Rastschulter in
Gegenstecker 3 überwunden hat. Gleichzeitig gibt sie den Raum 5 im
Bereich der freien Enden 4c, 4d der Sekundärverriegelungszungen 4a, 4b
wieder frei, bietet somit keine Anlagenflächen mehr, so daß diese auf Grund
der elastischen Verbiegung der Sekundärverrieglungszungen 4a, 4b hinter
die Verriegelungszunge 2 in den Raum 5 springen, wie dies in Figur 4b
gezeigt ist. Damit ist die Sekundärverriegelung hergestellt, weil die
Verriegelungszunge 2 sich nicht mehr aus ihrer verrasteten Stellung in
Richtung auf die Steckachse bewegen kann. In the locked state, i. the connector 1 is completely in the
