Description

Die Erfindung betrifft einen Steckverbinder gemƤƟ dem Oberbegriff von Anspruch 1.The invention relates to a connector according to the preamble of claim 1.

Insbesondere betrifft die vorliegende Erfindung einen derartigen Steckverbinder fĆ¼r den Einsatz im Hochtemperaturbereich. Im Rahmen dieses Schutzrechts soll "Hochtemperaturbereich" einen Temperaturbereich bedeuten, bei dem fĆ¼r den Steckverbinder und das Kabel spezielle Materialien eingesetzt werden mĆ¼ssen, die den hohen Temperaturen standhalten. In der Regel sind das Temperaturen von mehr als 120Ā°C. Die obere Temperaturgrenze von Steckverbindern und Kabeln, die im Hochtemperaturbereich eingesetzt werden, betrƤgt in der Regel 250Ā°C. Es ist klar, dass je nach den fĆ¼r den Steckverbinder und das Kabel verwendeten Materialien andere fĆ¼r die speziellen Materialien geltende Temperaturgrenzen den Hochtemperaturbereich definieren.In particular, the present invention relates to such a connector for use in the high temperature range. Within the scope of this intellectual property right, "high temperature range" shall mean a temperature range in which special materials must be used for the connector and the cable to withstand the high temperatures. As a rule, temperatures of more than 120 Ā° C. The upper temperature limit of connectors and cables used in the high temperature range is usually 250 Ā° C. It is clear that, depending on the materials used for the connector and the cable, other temperature limits for the particular materials define the high temperature range.

Es ist bekannt, Steckverbinder gemƤƟ dem Oberbegriff von Anspruch 1 fĆ¼r den Raumtemperaturbereich einzusetzen. Durch das Umspritzen eines GehƤuses auf den KontakttrƤger und das Kabel wird ein fertig konfektioniertes Steckverbinder mit einem bestimmter Kabel bestimmter LƤnge geschaffen. Bei dem sich keine fluiddichte Verbindung ausbildet. Insofern gibt es keine Steckverbinder gemƤƟ dem Oberbegriff von Anspruch 1, die fĆ¼r den Hochtemperatur einsetzbar und gleichzeitig fluiddicht sind.It is known to use connectors according to the preamble of claim 1 for the room temperature range. By encapsulating a housing on the contact carrier and the cable a ready-made connector with a certain cable length is created. In which no fluid-tight connection is formed. In this respect, there are no connectors according to the preamble of claim 1, which can be used for high temperature and at the same time fluid-tight.

Aus der DE 94 10 092 und aus der US 5,797,761 ist ein Kupplungsteil einer elektrischen Leitungskupplung fĆ¼r mindestens zwei Adern aufweisende elektrische Leitungen bekannt, in welchem die abisolierten Leiter der Adern elektrisch leitend mit metallischen Kontaktteilen verbunden sind, die in Durchgangslƶcher eines aus Isoliermaterial bestehenden TrƤgers eingesteckt sind, in welchem auf der der jeweiligen Leitung zugewandten FlƤche des. TrƤgers ein HeiƟschmelzkleber aufgebracht ist und in welchem unter Freilassung der der Kontaktgabe mit Gegenkontakten dienenden Enden der Kontaktteile um den TrƤger und das Ende der jeweiligen Leitung herum ein Schutzkƶrper aus Isoliermaterial herumgespritzt ist, wobei innerhalb der Durchgangslƶcher Dichtungselemente (7) angebracht sind, durch welche die Durchgangslƶcher (6) hermetisch abgedichtet sind.From the DE 94 10 092 and from the US 5,797,761 a coupling part of an electrical line coupling for at least two wires having electrical lines is known in which the stripped conductor of the wires are electrically connected to metallic contact parts, which are inserted into through holes of a carrier consisting of insulating material, in which on the respective line facing surface the support. A hot melt adhesive is applied and in which while leaving the contact with mating contacts serving ends of the contact parts around the carrier and the end of the respective line around a protective body of insulating material is sprayed around, wherein within the through holes sealing elements (7) are mounted through which the through holes (6) are hermetically sealed.

Die WO 2005/101582 A1 offenbart einen elektrischen Verbinder nach Art eines ReiƟverschlusses. Jeder Steckerteil weist eine Reihe beabstandeter Kontaktelemente auf, wobei die Kontaktelemente des einen Steckerteiles in die ZwischenrƤume zwischen den Kontaktelemente des anderen Steckerteils eingefĆ¼hrt werden kƶnnen.The WO 2005/101582 A1 discloses an electrical connector in the manner of a zipper. Each plug part has a number of spaced contact elements, wherein the contact elements of a plug part can be inserted into the spaces between the contact elements of the other plug part.

Aus der De 2000 12 284 U1 ist ein elektrischer Steckverbinder bekannt, mit einem aus Isolierstoff vorgefertigten KontakttrƤger, in den KontaktkanƤle zur Aufnahme einzelner Kontakte eingearbeitet sind, sowie mit einem fest mit dem KontakttrƤger verbundenen Griffkƶrper, welcher einstĆ¼ckigstoffschlĆ¼ssiger Bestandteil des vorgefertigten KontakttrƤgers ist und KanƤle zum Einstecken isolierter Litzen einer Anschlussleitung aufweist, so dass diese LitzenkanƤle die KontaktkanƤle im KontakttrƤger unter einem Winkel queren und die KontaktkanƤle Kontakte aufnehmen, die rĆ¼ckwƤrtig mit je wenigstens einer Spitze zum Eindringen in eine Litze versehen sind und von einer unwirksamen Stellung innerhalb des Kontaktkanals in eine Kontaktstellung verschiebbar sind, in der sich die Eindringspitze in der im Litzenkanal bereitgehaltenen Litze befindet.From the De 2000 12 284 U1 an electrical connector is known, with a prefabricated from insulating contact carrier, are incorporated in the contact channels for receiving individual contacts, and with a fixedly connected to the contact carrier handle body, which is einstĆ¼ckigstoffschlĆ¼ssiger part of the prefabricated contact carrier and channels for inserting insulated strands of a connecting line, so these stranded channels traverse the contact channels in the contact carrier at an angle and record the contact channels contacts, which are provided with at least one rear tip for penetration into a strand and from an inactive position within the contact channel in a contact position are displaced, in which the Eindringpitze in the im Litzenkanal ready held strand is located.

Die EP 1 381 114 A2 zeigt schlieƟlich einen Verbinder zur sicheren Verbindung von Kabeln, mit einer mƤnnlichen und einer weiblichen Kupplung, welche mit jeweils einem Kabel verschraubt sind. Die weibliche Kupplung enthƤlt darĆ¼ber hinaus ein Dichtelement, welches an einem Vorspruch der mƤnnlichen Kupplung dichtend anliegt.The EP 1 381 114 A2 shows finally a connector for secure connection of cables, with a male and a female coupling, which are bolted to one cable. The female coupling further includes a sealing element, which sealingly bears against a projection of the male coupling.

Ein weiterer Stecker aus dem Stand der Technik wirk in DE 11 65 120 B beschriben.Another plug of the prior art is effective in DE 11 65 120 B beschriben.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Steckverbinder gemƤƟ dem Oberbegriff von Anspruch 1 derart weiterzubilden, dass der Steckverbinder fĆ¼r den Hochtemperatur einsetzbar und gleichzeitig fluiddicht ist.The invention is therefore the object of developing a connector according to the preamble of claim 1 such that the connector for high temperature can be used while fluid-tight.

GemƤƟ einer AusfĆ¼hrung der Erfindung umfasst ein Steckverbinder ein Kabel, das mindestens eine Leitung aufweist, einen KontakttrƤger, der mindestens ein Kontaktelement aufweist, das an die mindestens eine Leitung des Kabels angeschlossen ist, eine Umspritzung, die um das Kabel und den KontakttrƤger gespritzt ist, und ein Dichtglied zur Abdichtung der Umspritzung gegenĆ¼ber dem AuƟenmantel des Kabels.According to an embodiment of the invention, a connector comprises a cable having at least one lead, a contact carrier having at least one contact element connected to the at least one lead of the cable, an overmoulding injected around the cable and the contact support, and a sealing member for sealing the encapsulation with respect to the outer jacket of the cable.

Durch das Vorsehen einer Dichtglieds ist es mƶglich den erfindungsgemƤƟen Steckverbinder auch im Hochtemperaturbereich einzusetzen. Bislang war das nicht mƶglich, weil eine Verbindung und damit eine Abdichtung zwischen dem wƤrmebestƤndigen AuƟenmantel des Kabels und der Umspritzung beim Umspritzen nicht ausgebildet wird. Daher hat man bisher im Hochtemperaturbereich nur Steckverbinder mit einem GehƤuse eingesetzt, das gegen den AuƟenmantel des Kabels abgedichtet ist. Der Einsatz von Umspritzungen fĆ¼r Steckverbinder fĆ¼r den Einsatz im Hochtemperaturbereich war bislang weder mƶglich noch bekannt, wenn gleichzeitig eine fluiddichte Abdichtung erforderlich ist.By providing a sealing member, it is possible to use the connector according to the invention also in the high temperature range. So far, this was not possible, because a connection and thus a seal between the heat-resistant outer jacket of the cable and the encapsulation during encapsulation is not formed. Therefore, it has been used in the high temperature range only connector with a housing which is sealed against the outer jacket of the cable. The use of overmoulding for Connectors for use in the high temperature range has hitherto been neither possible nor known if a fluid-tight seal is required at the same time.

Das gleiche gilt fĆ¼r andere umspritzte Steckverbinder, bei denen die Materialien der Umspritzung und des Kabelmantels keine stoffliche Verbindung (Vernetzung) beim SpritzgieƟvorgang eingehen kƶnnen. Mit dem erfindungsgemƤƟen Steckverbinder ist es mƶglich, derartige Steckverbinder mit einer fluiddichten Abdichtung zwischen dem Kabelmantel und der Umspritzung zu versehen.The same applies to other overmolded connectors in which the materials of the encapsulation and the cable sheath can not enter into a material connection (cross-linking) during the injection molding process. With the connector according to the invention, it is possible to such connectors with a fluid-tight seal between the cable sheath and the encapsulation to provide.

Vorzugsweise wird bei dem erfindungsgemƤƟen Steckverbinder eine stoffliche Verbindung von dem KontakttrƤger und der Umspritzung erreicht. Das geschieht vorzugsweise durch die Verwendung von gleichen oder eine Verbindung eingehenden Kunststoffen bei dem SpritzgieƟprozess im Einlegeverfahren oder Zwei- oder Mehrkomponentenverfahren. Dabei wird vorzugsweise ein Vollkƶrper aus dem KontaktrƤger und der Umspritzung erzeugt, der in sich dicht ist. Der erfindungsgemƤƟe Steckverbinder braucht somit kein GehƤuse, denn die AuƟenkontur wird durch die Umspritzung gebildet. Die Abdichtung zwischen dem Vollkƶrper und dem Kabel erfolgt erfindungsgemƤƟ mit dem Dichtglied, das vorzugsweise auƟerhalb des Vollkƶrpers angeordnet ist und mittels geeigneten Mitteln gegen den Vollkƶrper gepresst wird. Das das Kabel umschlieƟende Dichtglied wird dabei gegen das Kabel und den Vollkƶrper gepresst, wodurch eine Abdichtung erfolgt. Die erfindungsgemƤƟen Steckverbinder kƶnnen derart ausgebildet werden, dass sie insbesondere zu Rundsteckverbindern nach der Rundsteckverbindernorm DIN EN 61076 oder nach entsprechenden Rundsteckverbindernormen anderer LƤnder kompatibel sind.Preferably, a material connection is achieved by the contact carrier and the encapsulation in the connector according to the invention. This is preferably done by the use of the same or a compound incoming plastics in the injection molding in the loading process or two- or multi-component process. In this case, a solid body of the contact carrier and the encapsulation is preferably generated, which is sealed in itself. The connector according to the invention thus needs no housing, because the outer contour is formed by the encapsulation. The seal between the solid body and the cable is carried out according to the invention with the sealing member, which is preferably arranged outside of the solid body and is pressed by suitable means against the solid body. The cable surrounding the sealing member is pressed against the cable and the solid body, whereby a seal is made. The connectors according to the invention can be designed such that they are compatible in particular to circular connectors according to the circular connector standard DIN EN 61076 or according to corresponding circular connector standards of other countries.

ErfindungsgemƤƟ kann das Dichtglied auƟerhalb der Umspritzung angeordnet sein. Das hat den Vorteil, dass das Dichtglied auf einfache Weise gegen die Umspritzung gepresst werden kann. Das Dichtglied umschlieƟt dabei vorzugsweise das Kabel des Steckverbinders.According to the invention, the sealing member may be arranged outside the extrusion coating. This has the advantage that the sealing member can be pressed in a simple manner against the encapsulation. The sealing member preferably encloses the cable of the connector.

ErfindungsgemƤƟ kann das Dichtglied gegen die Umspritzung gepresst angeordnet sein. Das Dichtglied umschlieƟt dabei das Kabel und wird durch das Anspressen sowohl gegen die Umspritzung als auch gegen das Kabel gedrĆ¼ckt, wodurch eine gute Abdichtung gewƤhrleistet ist.According to the invention, the sealing member can be arranged pressed against the encapsulation. The sealing member encloses the cable and is pressed by the pressing against both the encapsulation and against the cable, whereby a good seal is ensured.

Das Kabel 10 ist aus wƤrmebestƤndigen Material ausgebildet, wobei sein AuƟenmantel aus einem wƤrmebestƤndigen Kunststoff ausgebildet ist, vorzugsweise aus Teflon. In dem Kabel 10 sind zwei Leitungen 11 vorgesehen, die mittels jeweils einem Anschlusselement 12 auf bekannte Weise mit einem Kontaktelement 13 (weiblich) verbunden sind. Die Verbindung kann auf eine beliebige dem Fachmann bekannte Weise erfolgen, die fĆ¼r Hochtemperatursteckverbinder geeignet sind.The in the FIGS. 1, 3 and 5 shown connector (mating connector part) is pre-assembled with a cable 10 of a certain length. The cable 10 is formed of heat-resistant material, wherein its outer jacket is formed of a heat-resistant plastic, preferably made of Teflon. In the cable 10, two lines 11 are provided, which are connected by means of a respective connecting element 12 in a known manner with a contact element 13 (female).
