Description

Die Erfindung betrifft einen gedichteten, elektrischen Stecker zur Verwendung in Applikationen für high speed Datenübertragung.The invention relates to a sealed, electrical connector for use in applications for high-speed data transmission.

Mit der Weiterentwicklung der elektronischen Fahrerassistenzsystemen verändern sich die Fahrzeuge und die dazugehörige Technologie. Die Menge an Daten, die zum Beispiel von einem Kamera-Array erzeugt werden, können über ein herkömmliches Controller Area Network (CAN) - Kommunikationsnetz mit einer Übertragungsrate von ungefähr 500 kbps nicht mehr in Echtzeit übertragen werden. Eine Lösung verspricht der Ethernet Standard, der aus der Computertechnik bekannt ist. Er wird von den Fahrzeugherstellern als ein stabiles Kommunikations-Schema für zukünftige Fahrzeug-Netzwerke angesehen. Da sich die klimatischen Verhältnisse in einem Fahrzeug wesentlich von denjenigen in einer Büroumgebung unterscheiden, müssen die Verbindungselemente und elektrischen Leitungen auf den Einsatz im Fahrzeug angepasst werden. Die Komponenten müssen über ihren gesamten Lebenszyklus zuverlässig funktionieren und robust gegenüber starken Temperaturschwankungen und Vibrationseinfluss sein. Da sich intelligente Knoten auch in Bereichen befinden können, die erhöhter Feuchtigkeit ausgesetzt sind, wie zum Beispiel in einem Außenspiegel, müssen die Steckverbindungen in jedem Falle wasserdicht sein. Zudem müssen die Komponenten so klein wie möglich sein, um das benötigte Volumen im Fahrzeug gering zu halten. Natürlich sollen die Komponenten, wie es in der Automobilindustrie üblich ist, in der Herstellung und Montage besonders preiswert sein. All diese Anforderungen stellen die Entwickler vor Probleme.With the further development of electronic driver assistance systems, the vehicles and the associated technology are changing. The amount of data generated, for example, by a camera array can no longer be transmitted in real time over a conventional Controller Area Network (CAN) communication network at a transfer rate of approximately 500 kbps. One solution promises the Ethernet standard, which is known from computer technology. It is considered by the vehicle manufacturers as a stable communication scheme for future vehicle networks. Since the climatic conditions in a vehicle differ significantly from those in an office environment, the fasteners and electrical lines must be adapted to the use in the vehicle. The components must function reliably over their entire life cycle and be robust against strong temperature fluctuations and vibration. Since smart nodes can also be located in areas exposed to increased humidity, such as in an exterior mirror, the connectors must be watertight in all cases.

Of course, the components, as is customary in the automotive industry, should be particularly inexpensive to manufacture and assemble. All these requirements pose problems for the developers.

EP 0 727 844 A2 , EP 0 740 367 A1 , und EP 1 235 306 A2 offenbaren elektrische Stecker gemäß dem Oberbegriff des Anspruchs 1. Die Aufgabe der Erfindung ist es, einen elektrischen Stecker bereitzustellen, der in Fahrzeugen als Verbindungselemente in Hight-Speed-Datennetzen eingesetzt werden kann. Wobei der Stecker mechanisch robust sowie auch in Bereichen mit erhöhtem Feuchtigkeitsaufkommen einsetzbar sein muss. EP 0 727 844 A2 . EP 0 740 367 A1 , and EP 1 235 306 A2 disclose electrical connectors according to the preamble of claim 1. The object of the invention is to provide an electrical connector used in vehicles as connecting elements in hight-speed data networks can be used. Where the plug must be mechanically robust as well as in areas with increased moisture.

Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst.The object is solved by the subject matter of claim 1.

Insbesondere durch einen Elektrischer Stecker umfassend ein erstes Steckergehäuse, mit einer im Wesentlichen senkrecht zur Steckachse angeordneten Wand, wobei die Wand eine Öffnung zum Einführen eines zweiten Steckergehäuses aufweist. Von der Wand erstreckt sich, konzentrisch um die Öffnung, ein erster Kragen. Von der Wand erstreckt sich, konzentrisch um den ersten Kragen, ein zweiter Kragen, wobei der erste Kragen und der zweite Kragen voneinander beabstandet sind. Ein hülsenförmiges Kodierelement ist mit einem ersten Ende an dem freien Ende des ersten Kragens befestigt. Der erste Kragen und das hülsenförmige Kodierelement sind konzentrisch um die Öffnung angeordnet. In einem Dichtungsbereich zwischen dem ersten Kragen und dem zweiten Kragen ist ein Dichtelement angeordnet. Das hülsenförmige Kodierelement weist Stützmittel an seinem ersten Ende auf, die geeignet sind, das Dichtelement in seiner Position zu halten.In particular, by an electrical connector comprising a first connector housing, with a wall arranged substantially perpendicular to the plug-in axis, wherein the wall has an opening for insertion of a second connector housing. From the wall extends, concentrically around the opening, a first collar. Extending from the wall, concentrically about the first collar, is a second collar, the first collar and the second collar being spaced apart. A sleeve-shaped coding element is attached at a first end to the free end of the first collar. The first collar and the sleeve-shaped coding element are arranged concentrically around the opening. In a sealing region between the first collar and the second collar, a sealing element is arranged. The sleeve-shaped coding element has support means at its first end, which are adapted to hold the sealing element in its position.

Der mehrteilige Aufbau des erfinderischen Steckers erlaubt es, einen Stecker für eine Vielzahl verschiedener Gegenstecker oder Hubs anzupassen. Allein der Einsatz eines, je nach Verwendungszweck (Gegenstecker oder Hub), ausgewählten Kodiertelements entscheidet darüber, ob der Stecker mechanisch mit der Gegenstelle verbunden werden kann. Die Mehrzahl der Steckerkomponenten sind also für alle Anwendungen gleich und können in großer Stückzahl produziert werden, was die Kosten im Rahmen hält. Nur das Kodierelement variiert. Das Kodierelement ist ein relativ preiswertes Spritzgussteil, bei dem sich die Varianz nicht so sehr in den Kosten wiederspiegelt. Beim Zusammenbau des Steckers wird zuerst das Dichtelement auf den ersten Kragen geschoben und danach wird das Kodierelement am Ende des freien Endes des ersten Kragens befestigt. Das Dichtelement, das zwischen den beiden Kragen angeordnet ist und dort die Verbindungsstelle zur Umwelt abdichtet, wenn der Gegenstecker mit dem Stecker verbunden ist, wird vom Kodierelement in seiner Position gehalten. Das Dichtmittel in Position zu halten ist äußerst wichtig, da bei unkorrekter Abdichtung Feuchtigkeit im Stecker zu Korrosion der Kontaktteile als auch zu einem Kurzschluss zwischen den Kontaktteilen führen kann und dadurch Fehler im Netzwerk auftreten können.The multi-part structure of the inventive connector allows to adapt a connector for a variety of mating connectors or hubs. The use of one, depending on the intended use (mating connector or hub), selected Kodiertelements decides whether the plug can be mechanically connected to the remote station. The majority of plug components are the same for all applications and can be produced in large quantities, which keeps the costs under control. Only the coding element varies. The coding is a relatively inexpensive injection molded part, in which the variance is not so much in the Cost reflects. When assembling the plug, the sealing element is first pushed onto the first collar and then the coding element is attached to the end of the free end of the first collar. The sealing element, which is arranged between the two collars and there seals the connection point to the environment when the mating connector is connected to the plug, is held by the coding element in its position. Keeping the sealant in place is extremely important because if the seal is incorrect, moisture in the connector can result in corrosion of the contact parts as well as a short circuit between the contact parts, which can cause network failures.

Vorteilhafte Ausbildungen der Erfindung sind den Unteransprüchen, der Beschreibung und der Zeichnung zu entnehmen.Advantageous embodiments of the invention are described in the dependent claims, the description and the drawings.

Gemäß einer Ausführungsform weist ein erstes Ende des hülsenförmiges Kodierelements und das freie Ende des ersten Kragens Befestigungsmittel auf, die dazu geeignet sind, sie aneinander zu halten. Das Kodierelement kann sowohl lösbar als auch nicht lösbar mit dem freien Ende des ersten Kragens verbunden sein. Als Befestigungsmittel können, je nach Vorliebe und Anwendungsfall, schweißen, kleben aber auch clipsen oder Schrauben in Betracht gezogen werden.According to one embodiment, a first end of the sleeve-shaped coding element and the free end of the first collar have fastening means which are adapted to hold them together. The coding element can be connected both detachably and non-detachably to the free end of the first collar. As a fastener, depending on preference and application, welding, but also clipping or screws are considered.

Bevorzugt umfassen die Befestigungsmittel zylinderförmige Zapfen, die senkrecht von der Innenseite des hülsenförmigen Kodierelements ragen und mit kreisbogenförmigen Ausnehmungen im freien Ende zusammenwirken. Dieser Aufbau ist vorteilhaft, wenn eine lösbare Verbindung gewünscht wird. Die Kreisbogenförmigen Ausnehmungen sind so dimensioniert, dass die Zapfen hineinschnappen können und das Kodierelement sicher gehalten wird. Über die Dimensionierung des Kreisbogens und des Zapfendurchmessers lassen sich Verbindung sowie Lösekräfte einstellen.Preferably, the fastening means comprise cylindrical pins which protrude perpendicularly from the inside of the sleeve-shaped Kodierelements and cooperate with circular arc-shaped recesses in the free end. This construction is advantageous if a detachable connection is desired. The circular arc-shaped recesses are dimensioned so that the pins can snap in and the coding is held securely. The dimensioning of the arc and the diameter of the peg allow connection and release forces to be set.

Bevorzugt sind das erste Ende des hülsenförmigen Kodierelements und das freie Ende des ersten Kragens nur in einer spezifischen Ausrichtung zueinander miteinander verbindbar. Das Kodierelement lässt sich nur in einer Orientierung mit dem freien Ende des ersten Kragens verbinden, damit die Kodierungsmittel am zweiten Ende des Kodierelements immer in korrekter Position angeordnet sind.Preferably, the first end of the sleeve-shaped coding element and the free end of the first collar are connectable to each other only in a specific orientation. The coding element can only be connected in one orientation with the free end of the first collar, so that the coding means are always arranged in the correct position at the second end of the coding element.

Bevorzugt liegen das zweite Ende des hülsenförmigen Kodierelements und das freie Ende des zweiten Kragens nicht in einer Ebene, senkrecht zur Steckachse. Die Anforderung, das Kodierelement nicht wie üblicherweise bei herkömlichen Steckern mit dem freien Ende des zweiten Kragens abschließen zu lassen, kann daher kommen, dass das Kodierelement besonders geschützt werden soll. Dann kann der zweite Kragen in Steckrichtung länger ausgeführt werden. Wird der Kragen beim Zusammenstecken versehentlich gegen einen Gegenstand gedrückt (z. B. bei Blindmontage), schützt er das Kontaktelement. Das Kodierelement kann natürlich auch bewusst so dimensioniert werden, dass es über das freie Ende des zweiten Kragens ragt. Dieser Aufbau wird gewählt, wenn das Kodierelement als Führungselement zum Finden der korrekten Position zum Gegenstecker dient.Preferably, the second end of the sleeve-shaped coding element and the free end of the second collar are not in a plane perpendicular to the plug-in axis. The requirement that the coding element not be terminated with the free end of the second collar, as is usually the case with conventional plugs, can therefore come about in that the coding element is to be particularly protected. Then, the second collar can be made longer in the direction of insertion. If the collar is accidentally pressed against an object during assembly (eg blind assembly), it protects the contact element. Of course, the coding element can also be deliberately dimensioned such that it protrudes beyond the free end of the second collar. This structure is chosen when the coding element serves as a guide element for finding the correct position to the mating connector.

Bevorzugt ist die Ausdehnung des hülsenförmigen Kodierelements (50) in Steckrichtung größer als der Querschnitt des hülsenförmigen Kodierelements. Ein in Steckrichtung relativ langes Kodierelement bietet eine gute Führung entlang der Steckstrecke beim Zusammenstecken in den Gegenstecker. Wobei das Kodierelement in einem Führungsbereich des Gegensteckers teleskopisch gleitet.Preferably, the extension of the sleeve-shaped coding element (50) in the insertion direction is greater than the cross-section of the sleeve-shaped coding element. A coding element which is relatively long in the plug-in direction provides good guidance along the plug-in route when plugged into the mating plug. Wherein the coding element slides telescopically in a guide region of the mating connector.

Nach einer weiteren Ausführungsform ist innerhalb des Dichtungsbereiches der erste Kragen, auf einer dem Dichtelement zugewandten Dichtfläche, frei von Bindenähten und Graten. Der Dichtungsbereich muss unbedingt von Bindenähten und Graten frei sein, da das Dichtelement, das auf dieser Fläche angeordnet wird, sehr empfindlich auf Kanten reagiert und durch diese beschädigt werden könnte. Außerdem kann eine Bindenaht oder ein Grat das Dichtelement von der Dichtfläche abheben und das Dichtvermögen negativ beeinflussen.According to a further embodiment, within the sealing region of the first collar, on a sealing element facing the sealing surface, free of weld lines and burrs. It is imperative that the sealing area be free of weld lines and burrs as the sealing element placed on this surface may be very sensitive to edges and may be damaged by them. In addition, a weld line or a burr can lift the sealing element from the sealing surface and adversely affect the sealing capacity.

Bevorzugt besteht das Dichtelement aus Silikon oder enthält Silikon. Silikon hat eine Vielzahl von positiven Eigenschaften für Dichtungszwecke, insbesondere in Fahrzeugen. Zum Beispiel das Rückstellungsvermögen nach Montage und Alterung.The sealing element preferably consists of silicone or contains silicone. Silicone has a variety of positive properties for sealing purposes, especially in vehicles. For example, the recoverability after assembly and aging.

Nach einer weiteren Ausführungsform weist das hülsenförmige Kodierelement an einem zweiten Ende ein Kodiermittel auf, das dazu geeignet ist, in Kombination mit einem Kodiermittel eines Gegensteckers, das vollständige mechanische Zusammenstecken der Stecker zu ermöglichen oder zu verhindern. Das zweite Ende des Kodierelements ist dazu ausgebildet, zu entscheiden, ob der Gegenstecker als korrekt akzeptiert wird oder nicht.According to a further embodiment, the sleeve-shaped coding element at a second end on a coding means which is adapted, in combination with a coding means of a mating connector to enable or prevent the complete mechanical mating of the plug. The second end of the coding element is designed to decide whether the mating connector is accepted as correct or not.

Bevorzugt ist das Kodiermittel mindestens eine Ausnehmung im hülsenförmigen Kodierelements, die sich vom zweiten Ende des hülsenförmigen Kodierelements in Richtung des ersten Endes erstreckt. Die Ausführung des Kodiermittels als Ausnehmung ist besonders einfach herzustellen und funktioniert effektiv. Eine rechteckige Ausnehmung oder ein Schlitz, der sich vom Ende des Kodierelements in das Material hinein erstreckt, kann sowohl beim Spritzgießen des Teils als auch später durch zum Beispiel Fräsen eingefügt werden. Dieses erhöht die Flexibilität bei der Produktion.Preferably, the coding means is at least one recess in the sleeve-shaped coding element, which extends from the second end of the sleeve-shaped coding element in the direction of the first end. The execution of the coding means as a recess is particularly easy to manufacture and works effectively. A rectangular recess or slot extending into the material from the end of the coding element may be inserted both during injection molding of the part and later by milling, for example. This increases flexibility in production.

Als besonders vorteilhaft ist die Breite der Ausnehmung klein im Verhältnis zum Umfang des hülsenförmigen Kodierelements. Wird die Breite der Ausnehmung klein im Verhältnis zum Umfang des hülsenförmig Kodierelements gewählt, dann bleibt das hülsenförmig Kodierelement stabil gegen Kräfte, die aus einem falschen Montageversuch resultieren können. Nach einer weiteren Ausführungsform gibt die mindestens eine Ausnehmung über ihre Position und /oder Breite und/oder Tiefe und/oder Form die Kodierung vor. Das Kodierungsmittel kann alle denkbaren geometrischen Formen am zweiten Ende des Kodierelements annehmen. Auch dieses erhöht die Flexibilität bei der Produktion. Allerdings muss gewährleistet sein, dass der Gegenstecker ein entsprechendes Profil aufweist.As a particularly advantageous, the width of the recess is small in relation to the circumference of the sleeve-shaped coding element. If the width of the recess is chosen to be small in relation to the circumference of the sleeve-shaped coding element, then the sleeve-shaped coding element remains stable against forces that can result from a wrong assembly attempt. According to a further embodiment, the at least one recess predetermines the coding via its position and / or width and / or depth and / or shape. The coding means can assume all conceivable geometric shapes at the second end of the coding element. This also increases flexibility in production. However, it must be ensured that the mating connector has a corresponding profile.

Bevorzugt ist der Querschnitt des hülsenförmigen Kodierelements rechteckig und die mindestens eine Ausnehmung in einem ebenen Bereich des hülsenförmigen Kodierelements eingebracht. Eine rechteckige Ausführungsform unterstützt bei der Montage das Positionieren des Kodierelements auf dem ersten Kragen.Preferably, the cross section of the sleeve-shaped coding element is rectangular and the at least one recess is introduced in a flat region of the sleeve-shaped coding element. A rectangular embodiment assists in the positioning of the coding element on the first collar during assembly.

Bevorzugt ist der Querschnitt des hülsenförmigen Kodierelements quadratisch. Der quadratische Querschnitt erlaubt, das Dichtelement quadratisch auszuführen, was bei der Montage eine fehlerhafte Anordnung des Dichtelements auf dem ersten Kragen verhindert.Preferably, the cross section of the sleeve-shaped coding element is square. The square cross-section allows to execute the sealing element square, which prevents an incorrect arrangement of the sealing element on the first collar during assembly.

Nach einer weiteren Ausführungsform weist das hülsenförmigen Kodierelements in jedem ebenen Bereich eine Ausnehmung auf, wobei die Ausnehmungen nicht gleichmäßig über den Umfang des hülsenförmigen Kodierelements verteilt sind. Die ungleichmäßige Verteilung der Ausnehmungen ermöglicht eine Vielzahl von Kodiermöglichkeiten, bei gleichzeitiger guter Führung des Steckers in den Ausnehmungen beim Zusammenschieben der Stecker.According to a further embodiment, the sleeve-shaped coding element has a recess in each flat region, wherein the recesses are not distributed uniformly over the circumference of the sleeve-shaped coding element. The uneven distribution of the recesses allows a variety of coding possibilities, while at the same time good guidance of the plug in the recesses when pushing together the plug.

Vorteilhafterweise wird das Stützmittel durch die Endfläche des ersten Endes des Kodierelements gebildet. Die Endfläche bildet einen Anschlag für das Dichtelement, sodass das Dichtelement nicht über das freie Ende des ersten Kragens rutschen kann.Advantageously, the support means is formed by the end face of the first end of the coding element. The end surface forms a stop for the sealing element, so that the sealing element can not slip over the free end of the first collar.

Bevorzugt sind innerhalb des ersten Kragens Haltemittel zum Halten des zweiten Steckergehäuses vorgesehen. Die Haltemittel sind typischerweise Rastelemente, die das zweite Gehäuse in einer vorgegebenen Position im ersten Gehäuse halten.Holding means for holding the second plug housing are preferably provided within the first collar. The holding means are typically latching elements which hold the second housing in a predetermined position in the first housing.

Fig. 1 zeigt den erfinderischen Stecker 10 in einer perspektivischen Darstellung. Die Darstellung zeigt den Bereich, der beim Zusammenstecken mit dem Gegenstecker 110 verbunden wird. Der zweite Kragen 26 umschließt teilweise das Kodierelement 50, das wiederum das zweite Steckergehäuse 40 teilweise umschließt. Vom zweiten Ende 52 her erstrecken sich schlitzförmige Ausnehmungen 57, geradlinig, entlang der Steckachse X in das Material des Kodierelement 50. Das Kodierelement 50 hat in dieser Darstellung vier Ausnehmung 57 über seinen Umfang verteilt. Das zweite Steckergehäuse 40 befindet sich zentral gehalten im ersten Steckergehäuse 20. Das zweite Steckergehäuse 40 ist etwas zurückgesetzt im Verhältnis zum zweiten Ende 52 des Kodierelement 50 angebracht. So wird sichergestellt, dass beim Zusammenstecken zuerst das Kodierelement 50 seine Führung finden muss, bevor das zweite Steckergehäuse 40 sein Gegenstück findet. Dieser Aufbau schützt das kleine, zweite Steckergehäuse 40 vor Beschädigung. Fig. 1 shows the inventive plug 10 in a perspective view. The illustration shows the area which is connected to the mating connector 110 when plugged together. The second collar 26 partially encloses the coding element 50, which in turn partially surrounds the second connector housing 40. Slit-shaped recesses 57, rectilinearly extend from the second end 52 into the material of the coding element 50 along the insertion axis X. In this illustration, the coding element 50 has four recesses 57 distributed over its circumference. The second connector housing 40 is centrally held in the first connector housing 20. The second connector housing 40 is slightly set back relative to the second end 52 of the coding element 50. This ensures that when plugging first the coding element 50 must find his leadership before the second connector housing 40 finds its counterpart. This structure protects the small, second connector housing 40 from damage.

In Fig. 2 ist ein Teil des zweiten Kragens 26 entfernt worden, um den Blick auf das Dichtelement 30 und das vollständige Kodierelement 50 zu ermöglichen. Es ist gut zu sehen, dass das Dichtelement nicht verrutschen kann. Die Ausnehmungen 57 im Kodierelement 50 erstrecken sich in dieser Darstellung fast bis zum ersten Ende 51 des Kodierelement 50.In Fig. 2 a portion of the second collar 26 has been removed to allow the view of the sealing element 30 and the complete coding element 50. It is good to see that the sealing element can not slip. The recesses 57 in the coding element 50 in this illustration extend almost to the first end 51 of the coding element 50.

Fig. 3 zeigt in Explosionsdarstellung das erste Steckergehäuse 20, das Dichtelement 30 sowie das Kodierelement 50. In dieser Darstellung ist zu erahnen, wie der elektrische Stecker 20 zusammengebaut wird. Zuerst wird das Dichtelement 30 in den Dichtungsbereich 29 (hier nicht zu sehen) gebracht und danach das Kodierelement 50 an dem freien Ende des ersten Kragens befestigt. Das zweite Steckergehäuse 40 kann vor oder nach der Montage des Dichtelements 30 innerhalb des ersten Kragens 23 befestigt werden. Fig. 3 shows in exploded view, the first connector housing 20, the sealing element 30 and the coding element 50. In this illustration, one can imagine how the electrical connector 20 is assembled. First the sealing element 30 is brought into the sealing area 29 (not shown here) and then the coding element 50 is attached to the free end of the first collar. The second connector housing 40 may be secured within the first collar 23 before or after assembly of the sealing member 30.

Fig. 4 zeigt eine perspektivische Darstellung des Kodierelements 50, insbesondere seines ersten Endes 51. Hierbei ist zu sehen, dass eine umlaufende Endfläche 54 den Abschluss bildet. Diese Endfläche 54 verhindert ein Verrutschen des Dichtelements 30 im Dichtungsbereich 28. Des Weiteren sind Zapfen 55 dargestellt, die sich von der Innenseite des Kodierelements 50 erstrecken. Diese Zapfen 55 bilden zusammen mit den Ausnehmungen 31 im ersten Kragen 23 Haltemittel, die das Kodierelement 50 am freien Ende 25 des ersten Kragens 23 halten. Durch die Auswahl des Durchmessers der Zapfen 55 und der Form und Größe der Ausnehmungen 31 am freien Ende 25 des ersten Kragens 23 kann die zum Verbinden und Lösen benötigte Kraft eingestellt werden. Wie in Fig. 5 zu sehen ist, wird durch den ersten Kragen 23, den zweiten Kragen 26 und die Wand 21 ein in Steckrichtung X offener Dichtungsbereich 28 definiert. Beim Zusammenstecken mit einem Gegenstecker 110 schiebt sich ein Gegenkragen 126 in den Dichtungsbereich 28 und wird dort vom Dichtelement 30 gedichtet wie in Fig. 6 angedeutet. Fig. 4 shows a perspective view of the Kodierelements 50, in particular its first end 51. Here it can be seen that a circumferential end surface 54 forms the conclusion. This end surface 54 prevents slippage of the sealing element 30 in the sealing region 28. Further, pins 55 are shown, which extend from the inside of the coding element 50. These pins 55 together with the recesses 31 in the first collar 23 holding means that hold the coding element 50 at the free end 25 of the first collar 23. By selecting the diameter of the pins 55 and the shape and size of the recesses 31 at the free end 25 of the first collar 23, the force required for connection and release can be adjusted. As in Fig. 5 can be seen, is defined by the first collar 23, the second collar 26 and the wall 21 in the insertion direction X open sealing region 28. When mating with a mating connector 110, a counter-collar 126 pushes into the sealing region 28 and is sealed there by the sealing element 30, as in FIG Fig. 6 indicated.
