Die Bestandteile eines erfindungsgemäßen Steckverbinders 1 zeigt Fig. 1, von unten nach oben aufgelistet wie folgt: ein Gehäuse 6 mit einem Steckansatz 7 nimmt Kontakte 2 auf, einschließlich deren Ferritelemente 8. Das Gehäuse 6 wird durch einen Deckel 9 verschlossen, durch den ein Bügel 18 einer Sekundärverriegelung 19 durchgreift. Die Sekundärverriegelung 19 hat zwei Verraststellungen, eine Montage Stellung und eine Endstellung, in der sie die Verbindung zwischen dem Steckverbinder und dem Zünder eines Airbagsystems verriegelt. Kontakte 2 weisen ein Stecker- bzw. Buchsenende 3 auf und ein hinteres Anschlussende 4 zur Verbindung mit Anschlusskabeln 5. Der Deckel 9 wird auf dem Gehäuse 6 durch Verrasten von Rastlaschen 25 mit Rastnasen 24 befestigt. Durch das Verrasten des Deckels 9 auf dem Gehäuse 6 sind alle inneren Bestandteile des Steckverbinders lagegesichert.The components of a connector 1 according to the invention are shown in FIG. 1, listed from bottom to top as follows: a housing 6 with a plug-in projection 7 receives contacts 2, including their ferrite elements 8. The housing 6 is closed by a cover 9, through which a bracket 18 passes through a secondary lock 19. The secondary lock 19 has two locking positions, an assembly position and an end position in which it locks the connection between the connector and the igniter of an airbag system. Contacts 2 have a plug or socket end 3 and a rear connection end 4 for connection to connection cables 5. The cover 9 is fastened on the housing 6 by latching latching tabs 25 with latching lugs 24. By latching the cover 9 on the housing 6, all internal components of the connector are secured in position.

In Fig. 2(a) weist der linke Teil des Deckels 9 eine Klappe 10 auf, die um die Achse 12 nach oben verschwenkbar ist. DieIn Fig. 2 (a) the left part of the lid 9 has a flap 10 which can be pivoted upwards about the axis 12. The

Schwenkachse wird dadurch gebildet, dass der Deckel, der ein Kunststoffspritzgussteil ist, dort eine geringere Materialstärke aufweist, sodass die obere Klappe 10 um diese Materialverdünnung herum verschwenkbar ist. In geschlossener Stellung verrastet die obere Klappe 10 durch Rastlaschen 14 an entsprechenden Rastnasen 15 am Gehäuse 6. Auf der Oberseite der Klappe 10 sind Rastelemente 16 angebracht, die mit entsprechenden Rastelementen 17 an der gegenüberliegenden Kante des Bügels 18 der Sekundärverriegelung 19 einschnappen können, wodurch sowohl die Stellung des Bügels 18 der Sekundärverriegelung 19 als auch die geöffnete Stellung der oberen Klappe 10 fixiert sind. Eine ähnliche Befestigung der Klappe (11) ist (hier nicht gezeigt) am Gehäuse (G) möglich.The pivot axis is formed by the fact that the cover, which is a plastic injection molded part, has a lower material thickness there, so that the upper flap 10 surrounds it Material thinning is pivotable. In the closed position, the upper flap 10 latches by means of latching tabs 14 on corresponding latching lugs 15 on the housing 6. On the top of the flap 10, latching elements 16 are attached, which can snap into the corresponding latching elements 17 on the opposite edge of the bracket 18 of the secondary locking device 19, whereby both the position of the bracket 18 of the secondary lock 19 and the open position of the upper flap 10 are fixed. A similar fastening of the flap (11) to the housing (G) is possible (not shown here).

Fig. 2(a) zeigt den erfindungsgemäßen Steckverbinder 1 von schräg oben mit geöffneter oberer Klappe 10. Man erkennt, dass die Kabelanschlussenden 4 der Kontakte 2 bei geöffneter oberer Klappe 10 von oben frei zugänglich sind. Fig. 2(b) zeigt den Steckverbinder von unten, ebenfalls mit geöffneter unterer Klappe 11 , sodass der Anschlussbereich 4 der Kontakte 2 ebenfalls nach unten freiliegt. Damit ist die Möglichkeit geschaffen, bei sonst vollständig montiertem und geschlossenem Steckverbinder die Verdrahtung vorzugsweise durch Verkrimpen vorzunehmen. Dazu wird der Steckverbinder mit geöffneten Klappen 10 und 11 auf einen Krimpamboss (nicht gezeigt) abgelegt und die Kabelanschlussenden der Kontakte 2 werden durch ein Krimpwerkzeug von der gegenüberliegenden Seite aus verformt.2 (a) shows the connector 1 according to the invention from obliquely above with the upper flap 10 open. It can be seen that the cable connection ends 4 of the contacts 2 are freely accessible from above when the upper flap 10 is open. 2 (b) shows the connector from below, also with the lower flap 11 open, so that the connection area 4 of the contacts 2 is also exposed downward. This creates the possibility to carry out the wiring, preferably by crimping, when the connector is otherwise completely assembled and closed. For this purpose, the connector with flaps 10 and 11 open is placed on a crimping anvil (not shown) and the cable connection ends of the contacts 2 are deformed by a crimping tool from the opposite side.

In dieser Stellung sind die Ferritkerne und die Sekundärverriegelung 19 sowie die Kontakte 2 jeweils starr gehaltert, sodass es hier zu keinen Unregelmäßigkeiten kommen kann. Die Schutzmäntel der Kabel 5 sind in Zugentlastungen 21 eingepresst, die durch in das Mantelmaterial eingreifende Zähne die Kabel haltern. Um die Kabel 5 fester in die Zugentlastungen 21 zu pressen, sind auf der Unterseite des Deckels 10 Formteile 20 angeformt, die bei verrastetem Deckel 10 die Kabel 5 fester in die Zugentlastung 21 einpressen. Wie man in Fig. 2(b) erkennt, verrastet die untere Klappe 11 des Gehäuses 6 durch Rastschultern 22, die an den Seitenwänden der unteren Klappe 11 angeformt sind und die in entsprechende Nuten 23 an den Seitenwänden des Gehäuses 6 angeformt sind. Die untere Klappe 11 ist ebenfalls durch eine Materialverdünnung um eine Schwenkachse 13 verschwenkbar.In this position, the ferrite cores and the secondary locking device 19 and the contacts 2 are each rigidly held, so that there can be no irregularities here. The protective sheaths of the cables 5 are pressed into strain reliefs 21 which hold the cables by teeth engaging in the sheath material. To tighten the cables 5 in the strain relief 21 to be pressed, molded parts 20 are formed on the underside of the cover, which, when the cover 10 is locked, press the cables 5 more firmly into the strain relief 21. As can be seen in Fig. 2 (b), the lower flap 11 of the housing 6 latches by locking shoulders 22 which are integrally formed on the side walls of the lower flap 11 and which are formed in corresponding grooves 23 on the side walls of the housing 6. The lower flap 11 can also be pivoted about a pivot axis 13 by thinning the material.

Eine alternative Halte-Klemmvorrichtung für die untere Klappe 11 zeigen Fig. 3(a) und 3(b). Hier sind auf der Oberseite der Klappe 11 sich gegenüberliegende Klammern 26 angeordnet, die im aufgeklapptenAn alternative holding and clamping device for the lower flap 11 is shown in FIGS. 3 (a) and 3 (b). Here, on the upper side of the flap 11, opposing clamps 26 are arranged, which are in the opened position

This ensures that the lower flap 11 is kept open during z. B. guaranteed a curvature. 3 (b) shows the closed door 11.

Fig. 4(a) und 4(b) zeigen ein weiteres alternatives Halteelement für die untere und die obere Klappe. Hier werden beim Spritzgießen bei jeweils um etwa 90° geöffneten Klappen 10, 11 Halterippen 28a, 28b zwischen dem Gehäuse bzw. dem Deckel und der jeweils zugehörigen Klappe 10 bzw. 11 angegossen, die an Sollbruchstellen 29a bzw. 29b aufbrechen, sobald man versucht, die Klappen mit Kraft zu schließen. Damit sind dann die Klappen freigegeben. Nach erfolgter Verkrimpung der Kabelenden mit den Anschlussenden 4 der Kontakte 2 werden die Klappen 10 und 11 verschlossen und verrastet. Der Steckverbinder kann so unmittelbar an seinem Einsatzort verwendet werden, wobei Bügel 18 der Sekundärverriegelung 19 in einer Vormontagestellung verrastet ist und am Anwendungsort durch weiteres Eindrücken in seine Endraststellung überführt werden kann, wodurch den Steckerbinder endgültig verriegelt ist. Fig. 5 zeigt im Schnitt eine weitere Ausführungsform der Erfindung schematisch, wobei gleiche Bezugszeichen wie vorher gleiche Merkmale der Erfindung bezeichnen. Die Ausführungsform der Fig. 5 unterscheidet sich von den bisherigen Ausführungsformen dadurch, dass nicht getrennt Gehäuse 6 und Deckel 9 vorgesehen sind, sondern eine Aufnahme 40, die die Anschlussenden 4 der Kontakte und vorzugsweise auch die vorneliegenden (links in Fig. 5) Stecker- bzw. Buchsenenden 3 der Kontakte 2 umgibt und die in gleicher Weise wie die Kombination aus Gehäuse 6 und Deckel 9 zwei Öffnungen beidseits der Anschlussenden 4 der Kontakte 2 aufweisen. Mindestens eine der Öffnungen, vorzugsweise beide, sind durch Klappen 10 und 11 verschließbar. Deren Aufbau, Funktion und Einsatzweise ist die gleiche wie oben zu den Figuren 1 bis 4 beschrieben. Auch die Verriegelungen der Klappen und die sonstigen Merkmale des Steckverbinders können wie vorher beschrieben ausgebildet sein. Die Aufnahme 40 kann einstückig ausgebildet sein.4 (a) and 4 (b) show a further alternative holding element for the lower and the upper flap. Here, during injection molding with flaps 10, 11 each opened by approximately 90 °, retaining ribs 28a, 28b are cast between the housing or the cover and the associated flap 10 or 11, which break open at predetermined breaking points 29a or 29b as soon as one tries to to close the flaps with force. The flaps are then released. After crimping the cable ends to the connection ends 4 of the contacts 2, the flaps 10 and 11 are closed and locked. The connector can thus be used directly at its place of use, the bracket 18 of the secondary locking device 19 being locked in a preassembly position and being able to be brought into its final locking position at the application site by further pressing in, as a result of which the connector is finally locked. 5 schematically shows a section of a further embodiment of the invention, the same reference numerals as previously denoting the same features of the invention. The embodiment of FIG. 5 differs from the previous embodiments in that the housing 6 and cover 9 are not provided separately, but rather a receptacle 40 which connects the connecting ends 4 of the contacts and preferably also the front (left in FIG. 5) connector. or socket ends 3 of the contacts 2 and which, in the same way as the combination of housing 6 and cover 9, have two openings on both sides of the connection ends 4 of the contacts 2. At least one of the openings, preferably both, can be closed by flaps 10 and 11. The structure, function and mode of use is the same as described above for FIGS. 1 to 4. The latches of the flaps and the other features of the connector can also be designed as previously described. The receptacle 40 can be formed in one piece.

Die Skizze in Fig. 5 unten erläutert die Winkellagen derThe sketch in Fig. 5 below explains the angular positions of the

Wirkrichtungen von Stecker- bzw. Buchsenenden 3 und Anschlussenden 4 der Kontakte 2. Die Stecker- bzw.Direction of action of plug or socket ends 3 and connection ends 4 of contacts 2. The plug or

Buchsenenden 3 der Kontakte 2 können in der Ausführungsform der Fig. 5 in einer Richtung 41 verlaufen, die um einen Winkel α kleiner als 90° gegenüber der Verlängerung 42 der Richtung 43 der Anschlussenden 4 abgewinkelt sind, insbesondere weniger als 60°, vorzugsweise weniger als 20°. In der Fig. 5 liegt die Richtung des Stecker- bzw. Buchsenendes 3 in der Verlängerung der Richtung 43 des Anschlussendes 4 und bildet also mit ihm einen 180°-Winkel (α = 0°). In den Ausführungsformen der Figuren 1 bis 4 beträgt α vorzugsweise 70 bis 110°, weiter vorzugsweise 90°. Bei der Montage werden zunächst die Kontakte 2 in die Aufnahme 40 eingelegt. Dies kann durch Einschieben der Kontakte in Längsrichtung der Fig. 5 geschehen, also dort entweder von links oder vorzugsweise von rechts. Wenn es die geometrischen Verhältnisse erlauben oder sie durch Abwinkelung des linken Bereichs gegenüber dem rechten so gestaltet sind, kann das Einschieben auch durch eines der durch die Klappen 10, 11 verschließbaren Fenster erfolgen. Es erfolgt dann das Befestigen der Kabelenden 5 an den Anschlussenden 4 der Kontakte 2 durch Krimpen oder Löten und dann das Schließen der Klappen 10, 11.Socket ends 3 of the contacts 2 can in the embodiment 5 run in a direction 41 which are angled by an angle α less than 90 ° with respect to the extension 42 of the direction 43 of the connection ends 4, in particular less than 60 °, preferably less than 20 °. 5, the direction of the plug or socket end 3 lies in the extension of the direction 43 of the connection end 4 and thus forms a 180 ° angle (α = 0 °) with it. In the embodiments of FIGS. 1 to 4, α is preferably 70 to 110 °, more preferably 90 °. During assembly, the contacts 2 are first inserted into the receptacle 40. This can be done by inserting the contacts in the longitudinal direction of FIG. 5, ie there either from the left or preferably from the right. If the geometric conditions allow it or if they are designed in this way by angling the left area from the right area, the insertion can also take place through one of the windows which can be closed by the flaps 10, 11. The cable ends 5 are then attached to the connection ends 4 of the contacts 2 by crimping or soldering and then the flaps 10, 11 are closed.

Es kann - wie in Fig.5 gezeigt - allgemein eine Befestigungsvorrichtung vorgesehen sein, um einen Kontakt an Gehäuse 6 und/ oder Deckel 9 oder ggf. der Aufnahme 40 gegen Verschiebung nach seiner Montage zu sichern bzw. um ihn zu befestigen.. Eine Befestigungseinrichtung kann eine nach vorne innen abstehende Zunge 61 des Gehäuses 6 oder Deckels 9 oder der Aufnahme 40 vorgesehen sein, die sich beim Einschieben des Kontakts 2 in das Gehäuse 6 und/ oder Deckel 9 oder ggf. Aufnahme 40 hinter einem Vorsprung oder einer Kante 62 des Kontakts 2, beispielsweise der Kante einer eingestanzten Öffnung 63, verhakt und so das Rückwärtsschieben des bei der Montage einmal eingeschobenen Kontakts 2 verhindert. Nach vorne kann ein Anschlag für den einzuschiebenden Kontakt bzw. für eine daran ausgebildete Fläche oder Kante vorgesehen sein.A fastening device can generally be provided, as shown in FIG. 5, in order to secure contact on the housing 6 and / or cover 9 or, if appropriate, the receptacle 40 against displacement after its assembly or to fasten it. A fastening device A tongue 61 of the housing 6 or cover 9 or the receptacle 40 protruding toward the inside can be provided which, when the contact 2 is inserted into the housing 6 and / or cover 9 or possibly receptacle 40 behind a projection or an edge 62 of the Contact 2, for example the edge of a stamped opening 63, hooked and thus prevents the contact 2, which was inserted once during assembly, from being pushed backwards. To the front, a stop can be provided for the contact to be inserted or for a surface or edge formed thereon.

Allgemein können eine oder mehrere der Klappen 10, 11 eine Rasteinrichtung 26,30 aufweisen, mit der die Klappen 10, 11 in der geöffneten Stellung arretierbar sind, so dass sie beim Verbinden des Kontakts 2 mit dem Kabel 5 in einer definierten, geöffneten Stellung gehalten werden, so dass die Klappen den Montagevorgang nicht stören. Mit der Rasteinrichtung kann eine Klappe 10, 11 an einem geeignet gestalteten Bereich des Gehäuses 6 und/ oder des Deckels 9 oder der Aufnahme 40 in der geöffneten Stellung lösbar verrastet werden. Die Rasteinrichtung kann einen Haken oder eine Klemmeinrichtung aufweisen.In general, one or more of the flaps 10, 11 can have a latching device 26, 30 with which the flaps 10, 11 can be locked in the open position, so that they are held in a defined, open position when the contact 2 is connected to the cable 5 so that the flaps do not interfere with the assembly process. With the latching device, a flap 10, 11 can be releasably latched to a suitably designed area of the housing 6 and / or the cover 9 or the receptacle 40 in the open position. The latching device can have a hook or a clamping device.
