Die Erfindung betrifft einen Steckverbinder für pyrotechnische Anwendungen in Kraftfahrzeugen, mit in einem Gehäuse angeordneten Kontaktbuchsen, mit einer Primärverriegelung zur Fixierung eines in die Kontaktbuchsen einsteckbaren Kontaktsteckers sowie mit einer Sekundärverriegelung.The invention relates to a connector for pyrotechnic applications in motor vehicles, arranged in a housing contact sockets, with a primary lock for fixing a plug-in contact sockets into the contact plug and a secondary lock.
Die Sekundärverriegelung dient zur Sicherung der Primärverriegelung. Die Anforderungen an die Haltbarkeit und insbesondere die Zuverlässigkeit solcher Steckverbinder sind aufgrund deren Anwendungsgebiet äußerst hoch. Verbesserungen der Zuverlässigkeit der bekannten Steckverbinder gehen, nicht zuletzt aufgrund der geringen Abmessungen, häufig zu Lasten der Funktionalität.The secondary locking serves to secure the primary lock. The durability requirements and in particular the reliability of such connectors are extremely high due to their field of application. Improvements in the reliability of the known connectors, not least due to the small dimensions, often at the expense of functionality.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder anzugeben, der bei Beibehaltung der Funktionalität einer Sekundärverriegelung äußerst zuverlässig und unanfällig gegen Umwelteinflüsse ist.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.The invention has for its object to provide a connector that is extremely reliable and not susceptible to environmental influences while maintaining the functionality of a secondary locking.
This object is achieved with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Aufgrund der erfindungsgemäßen Ausgestaltung des Steckverbinders wird das Steckerinnere vor Spritz- und/oder Strahlwassereintritt, bei gleichzeitiger Beibehaltung der Funktionalität der Sekundärverriegelung, geschützt. Um die Dichtfunktion zu gewährleisten, ist gemäß der Erfindung eine Dichtung vorgesehen, die derart angeordnet ist, dass eine Relativverschiebung der Sekundärverriegelung gegenüber der Dichtung bei Beibehaltung der Dichtfunktion möglich ist, um die Sekundärverriegelung von der Steckverbinderaußenseite her von einer Vorraststellung in eine Endraststellung zu verschieben. Durch die erfindungsgemäße Ausgestaltung des Steckverbinders ist es möglich, den Steckverbinder vormontiert und mit vorverrasteter Sekundärverriegelung auszuliefern. Bereits in dieser Vorraststellung übt die Dichtung ihre Dichtfunktion aus. Gemäß der Erfindung geht die Dichtfunktion auch während des Verschiebens der Sekundärverriegelung in die Endraststellung nicht verloren.Due to the inventive design of the connector, the plug interior is protected against spray and / or jet water entering, while maintaining the functionality of the secondary lock. In order to ensure the sealing function, a seal is provided according to the invention, which is arranged such that a relative displacement of the secondary locking relative to the seal while maintaining the sealing function is possible to move the secondary locking of the connector outside from a pre-locking position to a final locked position. The inventive design of the connector, it is possible pre-assembled the connector and deliver with pre-locked secondary lock. Already in this pre-locking position, the seal exerts its sealing function. According to the invention, the sealing function is not lost during the displacement of the secondary lock in the final locked position.
In Ausgestaltung der Erfindung ist mit Vorteil vorgesehen, dass die Sekundärverriegelung einen äußeren, vorzugsweise zumindest näherungsweise kreiszylinderförmigen, insbesondere umlaufenden, Dichtabschnitt aufweist. Durch die im Querschnitt kreisförmige Geometrie der Sekundärverriegelung wird eine gleichmäßige Spannungsverteilung und damit eine optimale Dichtwirkung erzielt.In an embodiment of the invention is advantageously provided that the secondary lock has an outer, preferably at least approximately circular cylindrical, in particular circumferential, sealing portion. Due to the circular cross-sectional geometry of the secondary locking a uniform stress distribution and thus an optimum sealing effect is achieved.
Um eine optimale Abdichtung bei gleichzeitiger Verschiebbarkeit der Sekundärverriegelung zu gewährleisten, ist mit Vorteil vorgesehen, dass die Dichtung einen radial innen umlaufenden Dichtwulst aufweist, der an dem Dichtabschnitt der Sekundärverriegelung anliegt. Mit Vorteil ist der Innenquerschnitt des Dichtwulstes formkomplementär zur Außenkontur des Dichtabschnitts ausgebildet. Bei einem Dichtabschnitt mit kreisförmigem Querschnitt ist der Querschnitt des Dichtwulstes demnach ebenfalls kreisförmig. Dabei sollte der Innendurchmesser des Dichtwulstes im nicht montierten Zustand kleiner sein als der Außendurchmesser des Dichtabschnitts.In order to ensure optimum sealing with simultaneous displaceability of the secondary locking, it is advantageously provided that the seal has a radially inwardly encircling sealing bead which rests against the sealing portion of the secondary locking. Advantageously, the inner cross section of the sealing bead is complementary in shape to the outer contour of the sealing portion. In a sealing section with a circular cross section of the cross section of the sealing bead is therefore also circular. In this case, the inner diameter of the sealing bead in the unassembled state should be smaller than the outer diameter of the sealing section.
Um zu verhindern, dass Spritzwasser durch die Sekundärverriegelung selbst in das Steckverbinderinnere eintritt, ist gemäß einer zweckmäßigen Ausgestaltung der Erfindung vorgesehen, dass der von dem Dichtabschnitt umschlossene Bereich der Sekundärverriegelung geschlossen ausgebildet ist. Insbesondere kann dieser Bereich wannenförmig ausgebildet sein und gleichzeitig als Betätigungsabschnitt dienen, um die Sekundärverriegelung von der Steckverbinderaußenseite her in ihre Endraststellung zu verschieben.In order to prevent splashing water from entering the connector interior itself through the secondary locking mechanism, it is provided according to an expedient embodiment of the invention that the area of the secondary locking mechanism enclosed by the sealing portion is designed to be closed. In particular, this area may be formed trough-shaped and at the same time serve as an actuating portion to move the secondary locking of the connector outside to its final locked position.
Um eine optimale Abdichtung der Sekundärverriegelung gegenüber dem Steckverbinderinneren zu erreichen, ist in Weiterbildung der Erfindung vorgesehen, dass die Sekundärverriegelung einen, vorzugsweise ringschulterförmigen, Axialanschlag zur Anlage an der Dichtung in der Endraststellung aufweist. In der Endraststellung liegt damit die Dichtung nicht nur in radialer, sondern auch in axialer Richtung an der Sekundärverriegelung an, was zu verbesserten Abdichtergebnissen führt.In order to achieve an optimal sealing of the secondary locking relative to the connector interior, it is provided in a further development of the invention that the secondary locking mechanism has an axial stop, preferably an annular shoulder, for engagement with the seal in the final locking position. In the final locked position so that the seal is not only in the radial, but also in the axial direction of the secondary lock, which leads to improved Abdichtergebnissen.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Dichtgeometrie der Sekundärverriegelungsdichtung in eine Gehäusedichtung integriert ist. Mit anderen Worten ist die Dichtung der Sekundärverriegelung einstückig mit der Gehäusedichtung ausgebildet. Hierdurch kann auf ein separates Bauteil verzichtet werden. Es ist von besonderem Vorteil, wenn die Dichtung der Sekundärverriegelung und die Gehäusedichtung durch Umspritzen des Steckverbinders mit einem dauerelastischen Material, insbesondere Polyurethan, in einem gemeinsamen Herstellungsschritt hergestellt ist. Bei diesem gemeinsamen Umspritzvorgang des Gehäuses kann die spätere Dichtung für die Sekundärverriegelung (Dichtwulst) im Umspritzwerkzeug durch Stempel freigespart werden. Die für die Sekundärverriegelung notwendigen Durchbrüche im Gehäuse werden durch Stempel verschlossen, worauf anschließend die Sekundärverriegelungsdichtung angeformt wird. Diese Dichtung liegt dann gegen den Dichtabschnitt der anschließend montierbaren Sekundärverriegelung unter Vorspannung an.According to a particularly advantageous embodiment of the invention, it is provided that the sealing geometry of the secondary locking seal is integrated in a housing seal. In other words, the seal is the Secondary lock formed integrally with the housing seal. This makes it possible to dispense with a separate component. It is of particular advantage if the seal of the secondary lock and the housing seal is produced by molding the connector with a permanently elastic material, in particular polyurethane, in a common manufacturing step. In this common encapsulation process of the housing, the later seal for the secondary locking (sealing bead) in the overmolding tool can be cleared by stamp. The necessary openings for the secondary locking in the housing are closed by stamp, whereupon the secondary locking seal is then formed. This seal is then applied against the sealing portion of the subsequently assembled secondary locking under bias.
Gemäß einer Weiterbildung der Erfindung ist vorgesehen, dass der Steckverbinder einen Rüsselbereich zur Aufnahme eines Kontaktsteckers aufweist und dass im Rüsselbereich eine, insbesondere umlaufende, Dichtung für den Kontaktstecker vorgesehen ist. Durch die Verwendung einer solchen Dichtung für den Kontaktstecker im Rüsselbereich können beispielsweise Anzünder kontaktiert werden, die über einen Standardisolierring mit Kurzschlussbrücke und Kodierungsbereich verfügen. Über die Kurzschlussbrücke des Steckverbinders kann in Ausgestaltung der Erfindung die korrekte Stellung der Dichtung abgefragt werden. Hierzu muss lediglich elektrisch gemessen werden, ob die Kontakte kurzgeschlossen sind oder nicht. Die Kontakte sind nach Verschieben der Sekundärverriegelung in ihre Endraststellung nicht mehr kurzgeschlossen. Da die Sekundärverriegelung nur bei eingestecktem Kontaktstecker in ihre Endraststellung verschoben werden kann, dient die Feststellung, dass kein Kurzschluss vorliegt, als Indikator für einen eingesteckten und abgedichteten Kontaktstecker.According to one embodiment of the invention, it is provided that the connector has a proboscis area for receiving a contact plug and that in the region of the proboscis a, in particular circumferential, seal is provided for the contact plug. By using such a seal for the contact plug in the trunk area, for example, lighters can be contacted, which have a standard insulating ring with shorting bridge and coding area. About the shorting bridge of the connector can be queried in an embodiment of the invention, the correct position of the seal. For this purpose, it is only necessary to measure electrically, whether the contacts are short-circuited or not. The contacts are no longer short-circuited after moving the secondary latch in its final locked position. Since the secondary lock can only be moved to its final locked position when the contact plug is inserted, the determination that there is no short circuit serves as an indicator for an inserted and sealed contact plug.
Um ein Eindringen von Dichtmasse beim Umspritzvorgang in das Gehäuse zu erschweren, ist mit Vorteil vorgesehen, dass das Gehäuse zwei, insbesondere verrastbare Bauteile umfasst, zwischen denen eine umlaufende Nut-Feder-Verbindung vorgesehen ist. Diese schützt das Innenleben des Steckers vor der unter hohem Druck stehenden Dichtungsmasse.
Im Folgenden wird die Erfindung anhand eines in der Zeichnung gezeigten Ausführungsbeispiels näher erläutert.In order to impede the penetration of sealing compound during the encapsulation process in the housing, it is advantageously provided that the housing comprises two, in particular latchable components between which a circumferential tongue and groove connection is provided. This protects the interior of the connector from the high pressure sealant.
In the following the invention will be explained in more detail with reference to an embodiment shown in the drawing.
