Description

Die Erfindung betrifft einen elektrischen Verbinder der im Oberbegriff des Anspruchs 1 angegebenen Art. Ein derartiger Verbinder ist in der EP-A-1 204 174 beschrieben.The invention relates to an electrical connector specified in the preamble of claim 1. Such a connector is described in EP-A-1 204 174.

Bei herkömmlichen elektrischen Verbindern wird das beim Bestücken des Verbinders, d.h. beim Einsetzen der elektrischen Kontakte in die zugeordneten Kammern zu verdrängende Dichtungsmaterial bis in die jeweilige Kammer durchgeführt, was relativ hohe Steckkräfte mit sich bringt und zu einer Beschädigung oder gar Zerstörung der Dichtung führen kann, was einem Ausfall des betreffenden Verbinders gleichkommt. Die hohen Steckkräfte bringen u.a. auch die Gefahr mit sich, dass die mit den Kontakten versehenen Leitungen leicht abknicken und sich die Kontakte bei der Herstellung der jeweiligen gewünschten elektrischen Verbindung nicht mehr richtig stecken lassen. Indem die Dichtung beim Einstecken eines jeweiligen Kontaktes in die zugeordnete Kammer im Bereich der eingangsseitigen Kante sowie der Wand der Kammer gequetscht wird und entsprechend zerstört werden kann, kann also Wasser in die jeweilige Kammer eindringen, wodurch die Funktionsfähigkeit des Verbinders zumindest erheblich beeinträchtigt wird. Auch beim Herausziehen der elektrischen Kontakte kann es insbesondere wieder aufgrund eines Einquetschens des zu verdrängenden Dichtungsmaterials zu einer Beschädigung oder Zerstörung der Dichtung kommen.In conventional electrical connectors, this is done when loading the connector, i. when inserting the electrical contacts into the associated chambers to be displaced sealing material carried out into the respective chamber, which brings relatively high insertion forces and can lead to damage or even destruction of the seal, which is equivalent to a failure of the relevant connector. The high insertion forces bring u.a. There is also the risk that the lines provided with the contacts will bend slightly and the contacts can no longer be properly inserted in the production of the respective desired electrical connection. By squeezing the seal upon insertion of a respective contact in the associated chamber in the region of the input side edge and the wall of the chamber and can be destroyed accordingly, so water can penetrate into the respective chamber, whereby the operability of the connector is at least significantly affected. Also, when pulling out the electrical contacts, it may in particular come due to a crushing of the seal material to be displaced to damage or destruction of the seal.

Bei dem aus der EP-A-1 204 174 bekannten elektrischen Verbinder ist die im Eingangsbereich der Kammer angeordnete Dichtung einstückig ausgeführt.In the electrical connector known from EP-A-1 204 174, the seal arranged in the entrance area of the chamber is made in one piece.

Der Erfindung liegt die Aufgabe zugrunde, einen verbesserten elektrischen Verbinder der eingangs genannten Art zu schaffen, bei dem die zuvor genannten Probleme auf möglichst einfache und zuverlässige Weise beseitigt sind.The invention has for its object to provide an improved electrical connector of the type mentioned, in which the aforementioned problems are eliminated in the simplest and most reliable manner.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die Dichtung, in Kontaktsteckrichtung betrachtet in zumindest zwei Schichten unterteilt ist.This object is achieved according to the invention in that the seal, viewed in Kontaktsteckrichtung is divided into at least two layers.

Damit besteht z.B. die Möglichkeit, mehrere Steckbereiche auf mehrere Lagen bzw. Schichten zu verteilen.There is e.g. the possibility of distributing several plug-in areas over several layers or layers.

Dabei wird durch den hinteren Aufnahmebereich das beim Einsetzen eines jeweiligen elektrischen Kontaktes verdrängte Dichtungsmaterial aufgenommen, so dass dieses nicht mehr in die betreffende Kammer gelangen kann. Eine Beschädigung der Dichtung ist somit ausgeschlossen. Zudem werden die Steckkräfte in dem gewünschten Bereich, d.h. relativ klein gehalten. Mit einem jeweiligen vorderen Aufnahmebereich ist auch beim Herausziehen der elektrischen Kontakte sichergestellt, dass es zu keiner Beschädigung der Dichtung kommt.In this case, the displaced upon insertion of a respective electrical contact sealing material is received by the rear receiving area, so that it can no longer get into the relevant chamber. Damage to the seal is thus excluded. In addition, the insertion forces in the desired area, i. kept relatively small. With a respective front receiving area is ensured even when pulling out the electrical contacts that there is no damage to the seal.

Zweckmäßigerweise nimmt der Querschnitt eines jeweiligen Aufnahmebereichs zur Dichtung hin zu. Was den hinteren Aufnahmebereich betrifft, so kann dieser also an seinem der Dichtung zugewandten Ende einen größeren Öffnungsquerschnitt besitzen als an seinem der Kammer zugewandeten Ende. Was den vorderen Aufnahmebereich betrifft, so kann dieser an seinem der Dichtung zugewandten Ende einen größeren Öffnungsquerschnitt besitzen als an seinem anderen, z.B. einer Einführöffnung zugewandten Ende.Conveniently, the cross section of a respective receiving area increases toward the seal. As far as the rear receiving area is concerned, it can therefore have a larger opening cross-section at its end facing the seal than at its end facing the chamber. As far as the front receiving area is concerned, it may have a larger opening cross section at its end facing the seal than at its other end, for example facing an insertion opening.

Der hintere Aufnahmebereich kann in Kontaktsteckrichtung betrachtet insbesondere zwischen der Dichtung und der Kammer bzw. zwischen der Dichtung und der eingangsseitigen Kammerkante vorgesehen sein.The rear receiving area may be provided in the contact insertion direction, in particular between the seal and the chamber or between the seal and the input-side chamber edge.

Der hintere Aufnahmebereich kann insbesondere eine Fuge oder dergleichen umfassen. Dasselbe gilt auch für den vorderen Aufnahmebereich. Auch dieser kann also beispielsweise wieder durch eine Fuge oder dergleichen gebildet sein.The rear receiving area may in particular comprise a joint or the like. The same applies to the front recording area. This, too, can thus be formed, for example, again by a joint or the like.

Bevorzugt ist der hintere Aufnahmebereich so dimensioniert, dass beim Bestücken des Verbinders zumindest im Wesentlichen kein Dichtungsmaterial in die Kammer gelangt.Preferably, the rear receiving area is dimensioned so that at least substantially no sealing material enters the chamber when equipping the connector.

Der vordere Aufnahmebereich kann insbesondere auf der Innenseite einer mit wenigstens einer Kontaktöffnung versehenen Stirnwand des Verbinders vorgesehen sein. Die Stirnwand kann beispielsweise durch eine Filmscharnierklappe oder dergleichen gebildet sein.The front receiving area may in particular be provided on the inside of an end wall of the connector provided with at least one contact opening. The end wall may be formed for example by a film hinge flap or the like.

Bei einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Verbinders ist der hintere Aufnahmebereich durch zwei einander gegenüberliegende, zur Dichtung hin divergierende Wände begrenzt. Ggf. kann auch der vordere Aufnahmebereich durch zwei solche einander gegenüberliegende, zur Dichtung hin divergierende Wände begrenzt sein.In a preferred practical embodiment of the connector according to the invention, the rear receiving area is bounded by two opposing walls diverging towards the seal. Possibly. The front receiving area may also be delimited by two such walls which are opposite each other and which tend to seal.

Von Vorteil ist insbesondere auch, wenn die Dichtung im Bereich eines jeweiligen elektrischen Kontaktes in Kontaktsteckrichtung betrachtet in zumindest zwei in Kontaktsteckrichtung einen Abstand voneinander aufweisende Steckbereiche unterteilt ist. Ist die Dichtung insgesamt in zumindest zwei Lagen bzw. Schichten unterteilt, so können die in Kontaktsteckrichtung einen Abstand voneinander aufweisenden Steckbereiche auf diese Lagen bzw. Schichten verteilt sein.It is particularly advantageous if the seal in the region of a respective electrical contact in the contact plug-in direction is divided into at least two plug-in areas spaced from one another in the contact plug-in direction. If the seal as a whole is subdivided into at least two layers or layers, then the plug-in regions which have a distance from one another in the contact plug-in direction can be distributed to these layers or layers.

Bei einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Verbinders ist ein jeweiliger Steckbereich für den zugeordneten elektrischen Kontakt mit einer Öffnung versehen, deren maximaler Durchmesser vorzugsweise kleiner als die maximale Querabmessung des betreffenden Kontaktes und insbesondere kleiner als der Außendurchmesser der betreffenden Leitung ist, an der der Kontakt vorgesehen ist.In an expedient practical embodiment of the connector according to the invention, a respective plug-in area for the associated electrical contact is provided with an opening whose maximum diameter is preferably smaller than the maximum transverse dimension of the respective contact and in particular smaller than the outer diameter of the respective line at which provided the contact is.

Die Erfindung ist bei allen gedichteten Verbindern anwendbar, deren Dichtung durch eine Blockdichtung gebildet oder in mehrere Lagen bzw. Schichten unterteilt ist.The invention is applicable to all sealed connectors whose seal is formed by a block seal or subdivided into multiple layers.

In den Fig. 1 bis 10 ist ein Ausführungsbeispiel eines elektrischen Verbinders 10 dargestellt, bei dem es sich beispielsweise um einen Steckverbinder handeln kann.1 to 10, an embodiment of an electrical connector 10 is shown, which may be, for example, a connector.

Der elektrische Verbinder 10 umfasst mehrere Kammern 12 zur Aufnahme von elektrischen Kontakten 14 sowie eine im Eingangsbereich der Kammern 12 angeordnete Dichtung 16. Beim Bestücken des elektrischen Verbinders 10 werden die elektrischen Kontakte 14 durch diese Dichtung 16 hindurchgesteckt oder hindurchgestochen.The electrical connector 10 comprises a plurality of chambers 12 for receiving electrical contacts 14 and a seal 16 arranged in the entry region of the chambers 12. When the electrical connector 10 is fitted, the electrical contacts 14 are inserted or pierced through this seal 16.

In Kontaktsteckrichtung KS betrachtet unmittelbar hinter der Dichtung 16 ist jeweils ein quer zur Kontaktsteckrichtung KS erweiterter Aufnahmebereich 18 für beim Hindurchstecken eines jeweiligen elektrischen Kontaktes 14 verdrängtes Dichtungsmaterial vorgesehen.Viewed in the contact plug-in direction KS immediately behind the seal 16, a receiving area 18, which is extended transversely to the contact plug-in direction KS, is provided for sealing material displaced when a respective electrical contact 14 is pushed through.

Alternativ oder zusätzlich kann auch unmittelbar vor der Dichtung 16 jeweils ein quer zur Kontaktsteckrichtung KS erweiterter Aufnahmebereich 20 vorgesehen sein. Ein solcher vorderer Aufnahmebereich 20 dient der Aufnahme von beim Herausziehen eines jeweiligen Kontaktes 14 verdrängtem Dichtungsmaterial.Alternatively or additionally, a receiving region 20 which is extended transversely to the contact plug-in direction KS can also be provided directly in front of the seal 16. Such a front receiving area 20 serves to receive sealing material displaced when a respective contact 14 is withdrawn.

Wie insbesondere anhand der Fig. 1, 3 und 10 zu erkennen ist, nimmt der Querschnitt eines jeweiligen Aufnahmebereichs 18, 20 zur Dichtung 16 hin zu.As can be seen in particular with reference to FIGS. 1, 3 and 10, the cross-section of a respective receiving region 18, 20 increases towards the seal 16.

Wie insbesondere anhand der Fig. 1 und 10 zu erkennen ist, ist ein jeweiliger hinterer Aufnahmebereich 18 in Kontaktsteckrichtung KS betrachtet zwischen der Dichtung 16 und der zugeordneten Kammer 12 bzw. zwischen der Dichtung 16 und der eingangsseitigen Kante 22 der Kammer 12 vorgesehen.As can be seen in particular with reference to FIGS. 1 and 10, a respective rear receiving portion 18 is seen in the contact plug KS viewed between the seal 16 and the associated chamber 12 and between the seal 16 and the input-side edge 22 of the chamber 12.

Der hintere Aufnahmebereich 18 kann beispielsweise eine Fuge umfassen. Entsprechend kann auch der vordere Aufnahmebereich 20 beispielsweise durch eine Fuge oder dergleichen gebildet sein.The rear receiving area 18 may, for example, comprise a joint. Accordingly, the front receiving area 20 may be formed, for example, by a joint or the like.

Der hintere Aufnahmebereich 18 ist nun bevorzugt so dimensioniert, dass beim Bestücken des elektrischen Verbinders 10 zumindest im Wesentlichen kein Dichtungsmaterial in die Kammer 12 gelangt.The rear receiving area 18 is now preferably dimensioned so that at least substantially no sealing material enters the chamber 12 when the electrical connector 10 is being fitted.

Der vordere Aufnahmebereich 20 ist auf der Innenseite einer mit wenigstens einer Kontaktöffnung 24 versehenen Stirnwand 26 des elektrischen Verbinders 10 vorgesehen. Dabei kann die Stirnwand 26 beispielsweise durch eine Filmscharnierklappe 28 oder dergleichen gebildet sein.The front receiving area 20 is provided on the inside of an end wall 26 of the electrical connector 10 provided with at least one contact opening 24. In this case, the end wall 26 may be formed, for example, by a film hinge flap 28 or the like.

Wie am besten anhand der Fig. 1 und 10 zu erkennen ist, ist der hintere Aufnahmebereich 18 im vorliegenden Fall durch zwei einander gegenüberliegende, zur Dichtung 16 hin divergierende Wände 18', 18" begrenzt.As can best be seen with reference to FIGS. 1 and 10, the rear receiving area 18 in the present case is bounded by two opposing walls 18 ', 18 "which are diverging towards the seal 16.

In gleicher Weise kann auch der vordere Aufnahmebereich 20 durch zwei einander gegenüberliegende, zur Dichtung 16 hin divergierende Wände 20', 20" begrenzt sein (vgl. insbesondere die Fig. 1 und 4).In the same way, the front receiving area 20 can also be delimited by two opposing walls 20 ', 20 "that are diverging towards the seal 16 (cf., in particular, FIGS. 1 and 4).

Die Dichtung 16 ist in Kontaktsteckrichtung KS betrachtet in mehrere Schichten oder Lagen unterteilt.

In the present exemplary embodiment, the seal 16 is subdivided into two successive layers 16 1 , 16 2 in the contact plug-in direction KS (cf., in particular, FIGS. 1, 3 and 4 to 7).

Überdies kann die Dichtung 16 im Bereich eines jeweiligen elektrischen Kontaktes 14 in Kontaktsteckrichtung KS betrachtet in zumindest zwei in Kontaktsteckrichtung KS einen Abstand a voneinander aufweisende Steckbereiche 30 unterteilt sein (vgl. insbesondere Fig. 1). Im vorliegenden Fall ist eine Unterteilung in zwei solche Steckbereiche 30 vorgesehen.Moreover, in the region of a respective electrical contact 14 in the contact plug-in direction KS, the seal 16 can be subdivided into at least two plug-in regions 30 having a distance a from one another in the contact plug-in direction KS (cf., in particular, FIG. In the present case, a subdivision into two such plug-in areas 30 is provided.

Beim vorliegenden Ausführungsbeispiel ist die Dichtung 16 beispielsweise in zwei Lagen oder Schichten 161, 162 unterteilt, und die in Kontaktsteckrichtung KS einen Abstand a voneinander aufweisenden Steckbereiche 30 sind auf diese Lagen bzw. Schichten 161, 162 verteilt.In the present exemplary embodiment, the seal 16 is subdivided, for example, into two layers or layers 16 1 , 16 2 , and the plug-in regions 30 having a distance a from one another in contact plug-in direction KS are distributed to these layers or layers 16 1 , 16 2 .

Ein jeweiliger Steckbereich 30 kann für den zugeordneten elektrischen Kontakt 14 beispielsweise mit einer Öffnung 32 versehen sein (vgl. insbesondere die Fig. 1 und 3 bis 5). Der maximale Durchmesser einer solchen Öffnung 32 ist vorzugsweise kleiner als die maximale Querabmessung des betreffenden elektrischen Kontaktes 14 und insbesondere kleiner als der Außendurchmesser der betreffenden Leitung, an der der Kontakt 14 vorgesehen ist.A respective plug-in area 30 can be provided, for example, with an opening 32 for the associated electrical contact 14 (cf., in particular, FIGS. 1 and 3 to 5). The maximum diameter of such an opening 32 is preferably smaller than the maximum transverse dimension of the relevant electrical contact 14 and in particular smaller than the outer diameter of the relevant line on which the contact 14 is provided.

Fig. 1 zeigt den elektrischen Verbinder 10 in einer schematischen Querschnittsdarstellung, in der die elektrischen Kontakte 14 (vgl. z.B. Fig. 2) der Übersichtlichkeit halber weggelassen sind. Ein entsprechender, in dem Verbinder 10 einsetzbarer elektrischer Kontakt ist beispielsweise in der Fig. 2 gezeigt.1 shows the electrical connector 10 in a schematic cross-sectional view, in which the electrical contacts 14 (cf., for example, FIG. 2) have been omitted for the sake of clarity. A corresponding electrical contact which can be inserted in the connector 10 is shown for example in FIG. 2.

Auch in diesem Fall sind die elektrischen Kontakte 14 (vgl. insbesondere wieder Fig. 2) der Übersichtlichkeit halber wieder weggelassen.Fig. 3 shows the electrical connector 10 in a schematic longitudinal sectional view. Also in this case, the electrical contacts 14 (cf., in particular, again FIG. 2) have been omitted for the sake of clarity.

Mit dem Doppelpfeil in der Darstellung gemäß Fig. 2 ist angedeutet, dass das beim Einstecken oder Herausziehen des elektrischen Kontaktes 14 verdrängte Dichtungsmaterial in dem hinteren Aufnahmebereich 18 bzw. dem vorderen Aufnahmebereich 20 aufgenommen wird.The double arrow in the representation according to FIG. 2 indicates that the sealing material displaced during the insertion or removal of the electrical contact 14 is received in the rear receiving region 18 or the front receiving region 20.

Fig. 4 zeigt den elektrischen Verbinder 10 in einer schematischen perspektivischen Teilansicht, wobei auch ein durch die Dichtung 16 hindurchzustechender elektrischer Kontakt 14 dargestellt ist. In einem solchen Fall ist der elektrische Kontakt 14 durch die Kontaktöffnung 24 der Filmscharnierklappe 28 hindurch lediglich bis an die Dichtung 16 herangeführt, jedoch noch nicht durch diese hindurchgesteckt.4 shows the electrical connector 10 in a schematic perspective partial view, whereby an electrical contact 14 to be pierced through the seal 16 is also shown. In such a case, the electrical contact 14 is brought through the contact opening 24 of the film hinge flap 28 only up to the seal 16, but not yet inserted therethrough.

Fig. 5 zeigt den elektrischen Verbinder 10 in einer Phase, in der der elektrische Kontakt 14 bereits so weit eingesetzt ist, dass er die erste Schicht 161 der Dichtung 16 durchsetzt.5 shows the electrical connector 10 in a phase in which the electrical contact 14 has already been inserted so far that it passes through the first layer 16 1 of the seal 16.

In Fig. 6 ist der elektrische Verbinder 10 in einer Phase gezeigt, in der der elektrische Kontakt 14 bereits so weit eingesetzt ist, dass er beide Schichten 161, 162 der Dichtung 16 durchsetzt.In Fig. 6, the electrical connector 10 is shown in a phase in which the electrical contact 14 is already used so far that it passes through both layers 16 1 , 16 2 of the seal 16.

Fig. 7 zeigt den elektrischen Verbinder 10 in einer Phase, in der der elektrische Kontakt 14 seine Endposition erreicht hat, in der er mit einem Ende in die betreffende Kammer 12 hineinragt und im Bereich seines anderen Endes von der Dichtung 16 umgeben ist.Fig. 7 shows the electrical connector 10 in a phase in which the electrical contact 14 has reached its end position in which it protrudes with one end into the relevant chamber 12 and is surrounded by the seal 16 in the region of its other end.

Fig. 8 zeigt in schematischer Draufsicht einen Teil des elektrischen Verbinders 10 bei geöffneter Filmscharnierklappe 28. Dabei sind die elektrischen Kontakte 14 und die Dichtung 16 der Übersichtlichkeit halber weggelassen.8 shows a schematic plan view of a part of the electrical connector 10 with the film hinge flap 28 open. The electrical contacts 14 and the seal 16 have been omitted for the sake of clarity.

In der Darstellung dieser Fig. 8 sind insbesondere wieder die beiden einander gegenüberliegenden, zur Dichtung 16 hin divergierenden Wände 18', 18" zu erkennen, die den hinteren Aufnahmebereich 18 seitlich begrenzen.In the illustration of FIG. 8, in particular, the two opposing walls 18 ', 18 "which are diverging relative to the seal 16 can again be seen, which delimit the rear receiving area 18 laterally.

Fig. 9 zeigt eine schematische Innenansicht eines Teils der Filmscharnierklappe 28. In der Darstellung dieser Fig. 9 sind die beiden einander gegenüberliegenden, zur Dichtung 16 hin divergierenden Wände 20', 20" zu erkennen, durch die der vordere Aufnahmebereich 20 seitlich begrenzt wird.9 shows a schematic inside view of a part of the film hinge flap 28. In the representation of this FIG. 9, the two opposing walls 20 ', 20 "diverging towards the seal 16 can be seen, by which the front receiving area 20 is bounded laterally.

Fig. 10 zeigt in schematischer Längsschnittdarstellung nochmals eine Kammer 12 des elektrischen Verbinders 10 mit einem an diese Kammer 12 angrenzenden hinteren Aufnahmebereich 18. Dabei ergibt sich im vorliegenden Fall pro Kammer jeweils ein Raumzuwachs von beispielsweise etwa 20 % für das beim Einsetzen des betreffenden elektrischen Kontaktes verdrängte Dichtungsmaterial.Fig. 10 shows in a schematic longitudinal sectional view again a chamber 12 of the electrical connector 10 with a chamber 12 adjacent to this rear receiving area 18. This results in the present case per chamber each an increase in space, for example, about 20% for the onset of the relevant electrical contact displaced sealing material.

Im vorliegenden Fall besitzen die Aufnahmebereiche 18, 20 beispielsweise einen trapezförmigen Querschnitt (vgl. z.B. die Figuren 1 und 10). Der jeweilige Querschnitt dieser Aufnahmebereiche 18, 20 kann grundsätzlich jedoch auch eine beliebige andere Form besitzen. So können diese Bereiche beispielsweise auch rechteckig, oval, rund, elliptisch usw. ausgestaltet sein.In the present case, the receiving areas 18, 20 have, for example, a trapezoidal cross section (cf., for example, FIGS. 1 and 10). The respective cross section of these receiving areas 18, 20 may, however, in principle also have any other shape. For example, these areas may also be rectangular, oval, round, elliptical, etc.
