Description

Die Erfindung betrifft einen Steckverbinder, vorzugsweise zur Anwendung im Automobilbereich, gemäß den Merkmalen des Oberbegriffes des Patentsanspruches 1.The invention relates to a connector, preferably for use in the automotive sector, according to the features of the preamble of patent claim 1.

Aus der EP 1 122 840 A1 sind Steckverbinder, insbesondere Stecker oder Buchsen, bekannt, die ein vorgefertigtes Gehäuse aufweisen. Dieses vorgefertigte Gehäuse besteht aus einem elektrisch nicht leitfähigen Material und wird beispielsweise in einem Kunststoffspritzgussverfahren hergestellt. Dieses Gehäuse weist Kontaktkammern auf, in welche Kontaktpartner (z.B. Kontaktstifte oder Kontaktbuchsen) einsetzbar und dort festlegbar sind. Die Kontaktpartner befinden sich am Ende eines elektrischen Leiters und sind mit diesem elektrisch kontaktiert. Die elektrische Kontaktierung des Kontaktpartners an dem elektrischen Leiter erfolgt vorzugsweise durch eine Crimpverbindung, die bezüglich der Kontaktsicherheit und Dauerhaltbarkeit besonders bei Anwendungen im Automobilbereich von Vorteil ist. Zur Erzielung einer Längswasserdichtigkeit, die gerade bei Anwendung solcher Steckverbinder im Automobilbereich von größter Bedeutung ist, ist es erforderlich, dass der Bereich, in dem der zumindest eine elektrische Leiter in das Gehäuse hinein geführt ist, mit einer Abdichtung versehen wird, so dass Wasser oder Feuchtigkeit, die sich an den elektrischen Leitern befindet, nicht in Richtung der Kontaktkammern, in denen sich die Kontaktpartner befinden, gelangen kann. Zu diesem Zweck ist bei der EP 1 122 840 A1 vorgesehen, dass das Gehäuse in dem Bereich, in der zumindest eine elektrische Leiter in das Gehäuse hineingeführt ist, mit einer Spritzgussmasse umgebbar ist. Damit wird in dem einen Endbereich des Steckverbinders eine Dichtung in einem Spritzgussverfahren hergestellt, so dass kein Wasser oder keine Feuchtigkeit mehr aus Richtung der elektrischen Leiter in Richtung der Kontaktkammern gelangen kann. Bei der EP 1 122 840 A1 wird weiterhin realisiert, dass diese Spritzgussmasse auch die Kontaktstelle (Crimpbereich) umgibt, an der der Kontaktpartner mit elektrischen Leiterenden elektrisch kontaktiert ist. Dies führt zu einer weiteren Erhöhung der Kontaktsicherheit und deren Dauerhaltbarkeit. Bei der Formgebung und der Verarbeitung der Spritzgussmasse ist allerdings darauf zu achten, dass diese Spritzgussmasse nicht in Richtung der Kontaktkammern gelangen kann. Um zu verhindern, dass die Spritzgussmasse in die Kontaktkammern eindringen kann, ist vorgesehen, dass das vorgefertigte Gehäuse, welches mit den Kontaktpartnern und den elektrischen Leitern vorbestückt ist, in ein Spritzgusswerkzeug eingesetzt wird, wobei dies einen Schieber aufweist, der derart in dem Spritzgusswerkzeug angeordnet wird, dass durch seine Anordnung verhindert wird, dass Spritzgussmasse bei deren Verarbeitung in die Kontaktkammern des Gehäuses eindringen kann. Ein solcher Schieber muss für jede Gehäusevariante extra angefertigt werden, wodurch die Werkzeugkosten hoch sind. Außerdem ist es erforderlich, für jede Bauweise eines Gehäuses bei dem Spritzgießwerkzeug einen darauf abgestimmten Schieber vorzusehen, so dass mit jedem Spritzgießwerkzeug auch nur ein bestimmter Steckverbinder herstellbar ist.From the EP 1 122 840 A1 are connectors, in particular plugs or sockets, known which have a prefabricated housing. This prefabricated housing is made of an electrically non-conductive material and is produced for example in a plastic injection molding process. This housing has contact chambers into which contact partners (eg contact pins or contact sockets) can be inserted and fixed there. The contact partners are located at the end of an electrical conductor and are electrically contacted with this. The electrical contacting of the contact partner to the electrical conductor is preferably carried out by a crimped connection, which is advantageous in terms of contact reliability and durability, especially in automotive applications. In order to achieve a longitudinal water-tightness, which is of great importance precisely when using such connectors in the automotive sector, it is necessary that the region in which the at least one electrical conductor is guided into the housing is provided with a seal, so that water or Moisture, which is located on the electrical conductors, not in the direction of the contact chambers, in which the contact partners are, can get. For this purpose is at the EP 1 122 840 A1 provided that the housing in the region in which at least one electrical conductor is guided into the housing, can be surrounded by an injection molding compound. Thus, in the one end portion of the connector, a seal is made in an injection molding process, so that no water or moisture from the direction of the electrical conductor in the direction of Contact chambers can get. In the EP 1 122 840 A1 is further realized that this injection molding compound also surrounds the contact point (crimp area), at which the contact partner is electrically contacted with electrical conductor ends. This leads to a further increase in contact reliability and their durability. When shaping and processing the injection molding compound, however, care must be taken that this injection molding compound can not get in the direction of the contact chambers. In order to prevent that the injection molding compound can penetrate into the contact chambers, it is provided that the prefabricated housing, which is pre-equipped with the contact partners and the electrical conductors, is inserted into an injection molding tool, wherein this has a slider which is arranged in the injection molding tool is that is prevented by its arrangement that injection molding compound can penetrate during their processing in the contact chambers of the housing. Such a slide must be made separately for each housing variant, whereby the tool costs are high. In addition, it is necessary to provide a matched slider for each construction of a housing in the injection mold, so that with each injection mold and only a particular connector can be produced.

Außerdem ist es bei der EP 1 122 840 A1 erforderlich, dass die elektrischen Leiter, bei denen es sich beispielsweise um Litzen oder Drähte mit einem Isoliermantel handeln kann, in einer vorgebbaren Anordnung in das Spritzgusswerkzeug eingesetzt werden müssen. Dies ist erforderlich, damit die Spritzgussmasse wirksam die Abdichtung bilden kann. Bisher wurden diese elektrischen Leiter zusammen geklemmt, wobei es aber durch die entstehenden Zwickel bei der Zusammenklemmung zu Überspritzungen im Abgangsbereich, also beim Übergang von dem vorgefertigten Gehäuse in Richtung der elektrischen Leiter, kommen kann. Durch diese entstehenden Zwickel kommt es bei Bewegungen der Steckverbindung, die bei Anwendung im Automobilbereich in Folge von Vibrationen typisch sind, zu Beschädigungen der elektrischen Leiter, so dass der durchgehende elektrische Kontakt nicht mehr sicher gewährleistet ist. Außerdem ist die Formgebung und Verarbeitung (der Umspritzungsprozess) je nach Bauart des elektrischen Leiters problematisch. Hierzu gehört, dass bei Ausführungen mit gemeinsamer Klemmung die Länge der Spritzgussmasse (Umspritzlänge) vergrößert werden muss, da der Bereich, wo die einzelnen elektrischen Leiter übereinander liegen, nicht als Umspritzlänge für die Dichtigkeit genutzt werden kann.Moreover, it is at the EP 1 122 840 A1 required that the electrical conductors, which may be, for example, strands or wires with an insulating jacket, must be used in a predetermined arrangement in the injection molding tool. This is necessary so that the injection molding compound can effectively form the seal. So far, these electrical conductors have been clamped together, but it can come through the resulting gusset in the Zusammenkleemmung to overjections in the outlet area, ie the transition from the prefabricated housing in the direction of the electrical conductors. As a result of the resulting gussets, movements of the plug connection which are typical for use in the automotive sector as a result of vibrations result in damage to the electrical conductors, so that the continuous electrical contact is no longer reliably ensured. In addition, the shape and processing (the encapsulation process) depending on the design of the electrical conductor is problematic. This includes that in versions with common clamping the length of the injection molding compound (Umspritzlänge) must be increased because the area where the individual electrical conductors are superimposed, can not be used as Umspritzlänge for the tightness.

Der gattungsbildende Stand der Technik ist in der US 6,832,931 B1 offenbart.The generic state of the art is in the US Pat. No. 6,832,931 B1 disclosed.

Der Erfindung liegt daher die Aufgage zu Grunde, die eingangs geschilderten Nachteile zu vermeiden, Insbesondere die Werkzeugkosten und damit die Herstellkosten eines Steckverbinders zu senken, den Spritzgießvorgang zu vereinfachen und die Dichtwirkung in Bezug auf die Längswasserdichtigkeit dadurch beizubehalten bzw. sogar noch zu steigern.The invention is therefore based on the charge to avoid the disadvantages described above, in particular to reduce the tooling costs and thus the manufacturing cost of a connector, to simplify the injection molding and thereby maintain the sealing effect with respect to the longitudinal water-tightness or even increase.

Diese Aufgabe ist durch die Merkmale des Patentenspruches 1 gelöst.This object is solved by the features of patent claim 1.

Es ist ein vor Beginn des Spritzgussvorganges in das vorgefertigte Gehäuse ersetzbarer Riegel vorgesehen, welcher ein Eindringen von Spritzgussmasse in einen Kontaktbereich des zumindest einen Kontaktpartners verhindert, wobei dieser Riegel nicht Bestandteil eines Spritzgusswerkzeuges zur Formgebung und Verarbeitung der Spritzgussmasse ist. Ausgehend davon Ist erfindungsgemaß vorgesehen, dass ein mehrere elektrische Leiter in einer vorgebbaren Lage zueinander festlegbares Element vorgesehen Ist, wobei dieses Element zumindest teilweise, insbesondere vollständig, mit der Spritzgussmasse umgebbar ist.It is provided before the beginning of the injection molding process in the prefabricated housing replaceable latch, which prevents penetration of injection molding compound in a contact region of at least one contact partner, said latch is not part of an injection molding tool for shaping and processing of the injection molding compound. Based on this is inventively provided that a plurality of electrical conductors is provided in a predetermined position to each other festlegbares element, said element is at least partially, in particular completely, with the injection-molding compound umvorbar.

Diese Lösung hat den Vorteil, dass solche Riegel mit der beschriebenen Funktion einfach und kostengünstig ebenfalls z.B. in einem Kunststoffspritzgussverfahren vorgefertigt werden können, wozu sie nach ihrer Fertigung nur noch In eine entsprechende Ausnehmung in dem vorgefertigten Gehäuse eingesetzt werden müssen, nachdem dort die Kontaktpartner In die Kontaktklammern eingesetzt worden sind. Die geometrische Form eines Riegels kann ohne weiteres auf jede beliebige Gehäuseform angepasst werden, so dass in besonders vorteilhafter Weise bei Änderungen der Gehäuseform auch entsprechend geänderte Riegel eingesetzt werden können, ohne dass des Spritzgusswerkzeug angepasst werden die beiden Kontaktreihen oder die mehreren Kontaktreihen eingebracht, um damit die ausreichende Abdichtung zu erreichen. Damit kann durch das Vorhandensein und das Einsetzen des Riegels in das vorgefertigte Gehäuse beim Spritzgusswerkzeug auf den bisher bekannten seitlichen Schieber verzichtet werden. Der erfindungsgemäße Riegel ist ein einfaches Bauteil, welches vor dem Umspritzen in das vorgefertigte Gehäuse eingesetzt wird und nach der Formgebung und Verarbeitung der Spritzgussmasse zur Bildung einer Abdichtung in dem Gehäuse verbleibt oder aus diesem entfernt werden kann. Der Riegel wird während des Umspritzvorganges geklemmt, um ein Eindringen des Umspritzmaterials in die Kontaktkammern zu verhindern. Durch die Klemmung und den direkten Kontakt mit Umspritzmaterial lässt sich der Riegel nicht immer ohne weiteres entfernen. Aus elektrischer Sicht ist durch den Riegel ein Trennung der beiden Kontaktreihen gegeben und als Vorteil zu sehen. Üblich sind Spritzwerkzeuge, aber grundsätzlich kann durch einen Verguß die Riegeltechnik ebenfalls angewandt werden.This solution has the advantage that such bars can be prefabricated with the described function easily and inexpensively, for example, in a plastic injection molding, what they need to be used after their production only in a corresponding recess in the prefabricated housing after there the contact partners In the Contact clips have been used. The geometric shape of a bolt can be easily adapted to any housing shape, so that in a particularly advantageous manner with changes in the housing shape and correspondingly changed latch can be used without the injection mold to be adjusted the two rows of contacts or the plurality of contact rows introduced so as to achieve sufficient sealing. This can be dispensed with by the presence and the onset of the bolt in the prefabricated housing in the injection molding on the previously known lateral slide. The latch according to the invention is a simple component which is inserted into the prefabricated housing before encapsulation and, after the shaping and processing of the injection molding compound, remains in the housing or can be removed therefrom to form a seal. The bolt is clamped during the encapsulation process in order to prevent penetration of the encapsulation material in the contact chambers. Due to the clamping and the direct contact with encapsulation material, the bolt can not always be easily removed. From an electrical point of view, a separation of the two rows of contacts is given by the bolt and to see as an advantage. Usual are injection molds, but in principle can be applied by a casting the bolt technology also.

Weiterhin ist erfindungsgemäß vorgesehen, dass ein mehrere elektrische Leiter in einer vorgebbaren Lage zueinander festlegbares Element vorgesehen ist, wobei dieses Element zumindest teilweise, insbesondere vollständig, mit der Spritzgussmasse umgebbar ist. Dieses Element hat die Aufgabe, die mehreren elektrische Leiter zueinander in einer vorgebbaren Lage zueinander zu positionieren, so dass dadurch Überspritzungen im Abgangsbereich vermieden werden. Außerdem kann durch die Lagepositionierung der einzelnen elektrischen Leiter zueinander bei gemeinsamer Klemmung durch das erfindungsgemäße Element die Umspritzlänge verkürzt werden. Ein solches Element kommt bei einreihigen Steckverbindern in Betracht, wenn die elektrischen Leiter Litzen, Kabel oder dergleichen, d.h. Einzelleiter, sind. Auch bei Folienleitern, Lichtwellenleitern und dergleichen kann bei einreihiger Ausführung des Steckverbinders das erfindungsgemäße Element zur Anwendung kommen, da mit diesem der Übergangsbereich des elektrischen Leiters in Richtung des Gehäuses des Steckverbinders definiert festgelegt wird. Besonders vorteilhaft ist die Anwendung des erfindungsgemäßen Elementes bei zwei- oder mehrreihigen Ausführungen der Steckverbinder, da hier durch die Vielzahl der einzelnen elektrischen Leiter oder auch des Vorhandenseins mehrerer übereinander liegender Folien, Lichtwellenleiter, oder dergleichen es besonders wichtig ist, dass zur Erzielung der Längswasserdichtigkeit eine definierte Lage der elektrischen Leiter im Übergangsbereich erzielt wird. Durch den Einsatz dieses auch als Distanzelement ausgebildeten erfindungsgemäßen Elementes zwischen den einzelnen elektrischen Leitern (Litzen, Kabel, Folien, Lichtwellenleiter und dergleichen) im Klemmebereich des Spritzgusswerkzeuges wird die Klemmung und die Lagepositionierung deutlich verbessert. Dadurch entstehen keine Zwickel mehr. Außerdem ist eine geringere Temperaturbeanspruchung der elektrischen Leiter gegeben, da sich die Temperatur auf einen größeren Bereich verteilt und gegebenenfalls auch in Richtung der elektrischen Leiter und in Richtung des Gehäuses abgeführt werden kann. Außerdem werden durch die Lagefixierung und die daraus resultierende Separierung der einzelnen elektrischen Leiter voneinander durch das erfindungsgemäße Element optimal mit Spritzgussmasse umgeben (umspült), so dass eine bestmögliche Längswasserdichtigkeit erzielt wird.Furthermore, the invention provides that a plurality of electrical conductors in a predeterminable position to each other festlegbares element is provided, said element is at least partially, in particular completely, umgewandbar with the injection molding compound. This element has the task of positioning the several electrical conductors to one another in a predeterminable position relative to one another, so that over-spraying in the outgoing region is avoided. In addition, can be shortened by the position positioning of the individual electrical conductors to each other in common clamping by the element according to the invention, the Umspritzlänge. Such an element comes in single-row connectors into consideration when the electrical conductors strands, cables or the like, ie individual conductors are. Even with foil conductors, optical waveguides and the like, the element according to the invention can be used in a single-row design of the connector, since this defines the transition region of the electrical conductor in the direction of the housing of the connector. Particularly advantageous is the application of the element according to the invention in two- or multi-row versions of the connector, as here by the plurality of individual electrical conductors or the presence of several superimposed films, optical fibers, or the like It is particularly important that a defined position of the electrical conductors in the transition region is achieved to achieve the longitudinal water-tightness. The use of this element, which is also designed as a spacer element, between the individual electrical conductors (strands, cables, foils, optical waveguides and the like) in the clamping region of the injection molding tool significantly improves the clamping and positional positioning. As a result, no gussets arise. In addition, a lower temperature stress on the electrical conductor is given, since the temperature can be distributed over a larger area and, if appropriate, can also be dissipated in the direction of the electrical conductors and in the direction of the housing. In addition, by the fixing of the position and the resulting separation of the individual electrical conductors from each other by the inventive element optimally surrounded with injection molding compound (lapped), so that the best possible longitudinal water resistance is achieved.

Das erfindungsgemäße Element zur Lagefixierung und Festlegung der einzelnen elektrischen Leiter ist Bestandteil des Gehäuses und einstückig mit diesem hergestellt. Dies hat den Vorteil, dass das Gehäuse schon einstückig, insbesondere in einem Spritzgussverfahren, mit dem Element zur Lagefixierung hergestellt werden kann, so dass dadurch der Herstellvorgang des Steckverbinders weiter vereinfacht wird. Denn nachdem die Kontaktpartner in die einzelnen Kontaktkammern des Gehäuses eingesetzt worden sind, können, manuell oder automatisiert, die elektrischen Leiter an dem Element festgelegt, insbesondere eingeklemmt werden. Die daraus resultierenden Vorteile sind weiter vorstehend schon beschrieben worden.The element according to the invention for fixing the position and fixing the individual electrical conductors is part of the housing and manufactured in one piece with this. This has the advantage that the housing can already be made in one piece, in particular in an injection molding process, with the element for fixing the position, thereby further simplifying the manufacturing process of the connector. Because after the contact partners have been used in the individual contact chambers of the housing, can manually or automatically, the electrical conductors are fixed to the element, in particular clamped. The resulting advantages have already been described above.

In Weiterbildung der Erfindung bilden der Riegel zur Verhinderung des Eindringens von Spritzgussmasse in die Kontaktkammern und das Element zur Festlegung der einzelnen elektrischen Leiter in einer vorgebbaren Lage zueinander ein einstückiges Bauteil, wobei der Riegel über ein Distanzelement mit dem Element zur Lagefixierung verbunden ist. Diese Ausführungsform hat den besonderen Vorteil, dass mit ein und demselben Element zwei Wirkungen erzielt werden. Denn dieses einstückige Bauteil, welches ebenfalls preiswert in einem KunststoffSpritzgussverfahren herstellbar ist, verhindert einerseits das Eindringen der Spritzgussmasse in die Kontaktkammern beim Umgeben des Endbereiches des Gehäuses mit der Spritzgussmasse, ermöglicht gleichzeitig aber die Festlegung der einzelnen elektrischen Leiter zueinander und in Bezug auf eine vorgebbare Lage auf das Gehäuse, so dass dadurch die Formgebung und Verarbeitung der Spritzgussmasse zur Erzielung der Abdichtung und der Längswasserdichtigkeit optimal durchgeführt werden kannIn a further development of the invention, the bolt to prevent the ingress of injection molding compound into the contact chambers and the element for fixing the individual electrical conductors in a predetermined position to each other form a one-piece component, wherein the bolt is connected via a spacer element with the element for fixing the position. This embodiment has the particular advantage that two effects can be achieved with one and the same element. Because this one-piece component, which is also inexpensive in a plastic injection molding process can be produced, on the one hand prevents the penetration of the injection molding compound into the contact chambers when surrounding the end portion of the housing with the injection molding compound, but at the same time allows the determination of the individual electrical conductors to each other and with respect to a predeterminable position on the housing, thereby forming and processing the injection molding compound to achieve the seal and the longitudinal water-tightness can be optimally performed

Figur 1 zeigt einen erfindungsgemäßen Steckverbinder 1 vor und nach dem Umspritzen mit einer Spritzgussmasse. In der linken Abbildung ist erkennbar, dass der Steckverbinder 1 ein vorgefertigtes Gehäuse 2 aufweist, wobei dieses vorgefertigte Gehäuse 2 in einem Kunststoffspritzgussverfahren mit einer Öffnung 22 hergestellt wird und bei diesem Beispiel zweireihig ausgebildet ist. Alternativ dazu sind auch einreihige Ausführungen und mehr als zweireihige Ausführungen denkbar. Das vorgefertigte Gehäuse 2 weist entsprechend der Anzahl der zum Einsatz kommenden Kontaktpartner (hier nicht dargestellt) Kontaktkammern 3 auf, in welche diese Kontaktpartner eingesetzt und dort festgelegt werden. Die Kontaktpartner selber sind am Ende von elektrischen Leitern 4 angeordnet und mit diesen elektrisch kontaktiert, wobei die elektrische Kontaktierung vorzugsweise über eine Crimpverbindung, alternativ aber auch über andere Verbindungen (z.B. Lötvorgang) verbindbar sind. Ein derart vorbereiteter und in der linken Darstellung der Figur 1 gezeigter Steckverbinder 1 wird in ein Spritzgusswerkzeug eingesetzt, wobei mit dem durchzuführenden Spritzgussschritt eine Spritzgussmasse 5 (siehe rechte Darstellung der Figur 1) das Gehäuse 2 und den Endbereich der elektrischen Leiter 4 umgeben soll. Diese Spritzgussmasse 5 hat die Aufgabe, den Übergangsbereich von dem Gehäuse 2 in Richtung der elektrischen Leiter 4 abzudichten und dort Längswasserdichtigkeit herzustellen. Das Spritzgusswerkzeug hat zur Formgebung und Verarbeitung entsprechende innere Konturen, wobei vor dem Einsetzen des vorbereiteten Steckverbinders 1 in das Spritzgusswerkzeug noch in eine Ausnehmung in dem vorgefertigten Gehäuse 2 ein erfindungsgemäßer Riegel 6 eingesetzt werden muss. Dieser Riegel 6 bewirkt, dass nach dem Einsetzen des vorbereiteten Steckverbinders 1 in das Spritzgusswerkzeug und der anschließenden Formgebung und Verarbeitung der Spritzgussmasse 5 diese nicht in Richtung des Kontaktbereiches der Kontaktpartner, also in Richtung der Kontaktkammern 3, eindringen kann. FIG. 1 shows a connector 1 according to the invention before and after encapsulation with an injection molding compound. In the left-hand illustration it can be seen that the connector 1 has a prefabricated housing 2, wherein this prefabricated housing 2 is produced in a plastic injection-molding method with an opening 22 and is formed in two rows in this example. Alternatively, single-row versions and more than two-row versions are also conceivable. The prefabricated housing 2 has according to the number of used contact partners (not shown here) contact chambers 3, in which these contact partners are used and fixed there. The Contact partners themselves are arranged at the end of electrical conductors 4 and contacted with these electrically, wherein the electrical contact preferably via a crimped connection, but alternatively also via other connections (eg soldering) are connectable. Such a prepared and in the left representation of FIG. 1 shown connector 1 is inserted into an injection molding tool, wherein with the injection molding step to be performed an injection molding compound 5 (see right illustration of FIG. 1 ) is to surround the housing 2 and the end region of the electrical conductors 4. This injection molding compound 5 has the task of sealing the transition region from the housing 2 in the direction of the electrical conductors 4 and to produce longitudinal water-tightness there. The injection molding tool has for shaping and processing corresponding inner contours, wherein prior to insertion of the prepared connector 1 in the injection mold still in a recess in the prefabricated housing 2, an inventive latch 6 must be used. This bar 6 causes that after insertion of the prepared connector 1 in the injection mold and the subsequent shaping and processing of the injection molding compound 5, this can not penetrate in the direction of the contact region of the contact partners, ie in the direction of the contact chambers 3.

Figur 2 zeigt ein erfindungsgemäßes Element zur Lagefixierung in einer vorgebbaren Lage zueinander der elektrischen Leiter 4, wobei dieses Element 7 ebenfalls in einem Kunststoffspritzgussverfahren hergestellt werden kann. Dabei ist die Formgebung des Elementes 7 dergestalt, dass es die einzelnen elektrischen Leiter 4 aufnimmt (z.B. durch einen Klemmvorgang) und ihre Lage zueinander fixiert. In Figur 2 (zweite Darstellung von links) ist weiterhin erkennbar, dass der Riegel 6 und das Element 7 zur Lagefixierung der elektrischen Leiter 4 ein einstückiges Bauteil bilden, wobei Riegel 6 und Element 7 über ein Distanzteil 8 miteinander verbunden sind. Durch diese Ausgestaltung wird der Spritzgussvorgang zur Herstellung des Steckverbinders 1 weiter verbessert, da durch den Riegel 6 einerseits die Kontaktkammern vor Eindringen von Spritzgussmasse geschützt sind, andererseits aber die einzelnen elektrischen Leiter 4 eine definierte Lage zueinander aufweisen, damit beim nachfolgenden Spritzgussvorgang die Spritzgussmasse 5 die elektrischen Leiter 4 optimal umspült. Dieser Spritzgussvorgang mit der Spritzgussmasse 5 ist in der zweiten Darstellung von rechts der Figur 2 gezeigt. In der rechten Darstellung der Figur 2 ist zu erkennen, dass nach dem ausgeführten Spritzgussvorgang das Distanzteil 8 entfernt worden ist. Dies ist nicht zwangsweise erforderlich, bietet sich aber an, um die Kompaktheit des hergestellten Steckverbinders 1 zu erhöhen. Soll das Distanzteil 8 entfernt werden, ist es erfindungsgemäß über Sollbruchstellen an dem Riegel 6 und/oder dem Element 7 angeformt, um es einfach abbrechen zu können. Denkbar ist aber auch, dass eine solche Sollbruchstelle nur an dem Element 7 vorhanden ist, damit dort das Distanzelement 8 abgebrochen werden kann, während der Riegel 6 an dem Distanzteil 8 verbleiben soll, wenn der Riegel 6 aus dem Gehäuse 2 entfernt werden soll. FIG. 2 shows an inventive element for fixing the position in a predetermined position to each other of the electrical conductor 4, wherein this element 7 can also be produced in a plastic injection molding process. The shape of the element 7 is such that it receives the individual electrical conductors 4 (for example, by a clamping operation) and fixes their position relative to one another. In FIG. 2 (Second illustration from the left) is further recognizable that the latch 6 and the element 7 for fixing the position of the electrical conductors 4 form a one-piece component, wherein the latch 6 and element 7 are connected to each other via a spacer 8. By this configuration, the injection molding process for the production of the connector 1 is further improved, as are protected by the latch 6 on the one hand, the contact chambers from ingress of injection molding compound, but on the other hand, the individual electrical conductors 4 have a defined position to each other, so in the subsequent injection molding process, the injection molding 5 electrical conductor 4 flows around optimally. This Injection molding process with the injection molding compound 5 is in the second representation from the right of FIG. 2 shown. In the right-hand illustration of the FIG. 2 It can be seen that after the executed injection molding process, the spacer 8 has been removed. This is not necessarily required, but offers itself to increase the compactness of the manufactured connector 1. If the spacer 8 are to be removed, it is formed according to the invention via predetermined breaking points on the latch 6 and / or the element 7 in order to be able to break it off easily. It is also conceivable that such a predetermined breaking point is present only on the element 7, so that there the spacer element 8 can be canceled while the latch 6 is to remain on the spacer 8 when the latch 6 is to be removed from the housing 2.

Die Figuren 3 und 4 zeigen erfindungsgemäße Steckverbinder 1, wobei in Figur 3 ein Stecker und in Figur 4 eine Buchse gezeigt ist. Diese Ausführungsformen unterscheiden sich durch das vorgefertigte Gehäuse, wobei aber das Grundprinzip des Riegels 6 bzw. des Elementes 7 und deren Funktionsweise erhalten bleibt. Die getrennt voneinander herzustellenden Stecker gemäß Figur 3 und Buchsen gemäß Figur 4 werden bei ihrem späteren Einsatz zusammen gesteckt, wobei einerseits durch diesen Zusammensteckvorgang und die Ausgestaltung der vorgefertigten Gehäuse sicher gestellt ist, dass in den Steckbereich und damit in den Kontaktbereich kein Wasser oder keine Feuchtigkeit eindringen kann. Damit dies auch nicht aus Richtung der elektrischen Leiter 4 erfolgt, ist eben die Spritzgussmasse 5 beim Übergangsbereich von dem Gehäuse 2 in Richtung der elektrischen Leiter 4 vorhanden. Bei der Ausführungsform gemäß Figur 4 ist der Riegel 6 nicht gezeigt, aber vorhanden. Im Gegensatz zu den in den vorangegangenen Figuren gezeigten Ausführungsformen ist das Element 7 zur Lagefixierung der einzelnen elektrischen Leiter 4 einstückig mit dem Gehäuse 2 ausgebildet und zusammen mit diesem hergestellt. Bei Figur 3 ist nicht unbedingt ein Riegel 6 vorhanden, da auf der Steckerseite ein Riegel nicht zwangsweise erforderlich ist, da die Möglichkeit besteht, die Stiftkontakte einzupressen. Trotzdem kann der Riegel 6 aber in einem solchen Fall bei einem Stecker vorhanden sein.The FIGS. 3 and 4 show inventive connector 1, wherein in FIG. 3 a plug and in FIG. 4 a jack is shown. These embodiments differ by the prefabricated housing, but the basic principle of the bolt 6 and the element 7 and their operation is maintained. The separately manufactured according to plug FIG. 3 and sockets according to FIG. 4 are plugged together during their later use, on the one hand ensured by this mating operation and the design of the prefabricated housing that in the mating region and thus in the contact area no water or moisture can penetrate. So that this does not take place from the direction of the electrical conductors 4, just the injection-molding compound 5 is present in the transition region of the housing 2 in the direction of the electrical conductors 4. In the embodiment according to FIG. 4 the latch 6 is not shown, but present. In contrast to the embodiments shown in the preceding figures, the element 7 for fixing the position of the individual electrical conductors 4 is integrally formed with the housing 2 and manufactured together with this. at FIG. 3 is not necessarily a latch 6 available because a bolt is not necessarily required on the connector side, since there is the possibility to press the pin contacts. Nevertheless, the latch 6 may be present in such a case with a plug.

Das bedeutet zusammenfassend, dass der Riegel 6 und das Element 7 separate Bauteile sein können, einstückig miteinander verbunden sind (insbesondere über das Distanzteil 8) oder Kombinationen davon realisiert sein können.This means in summary that the latch 6 and the element 7 can be separate components, are integrally connected to one another (in particular via the spacer 8) or combinations thereof can be realized.

Figur 5 zeigt einen Steckverbinder mit einem erfindungsgemäßen Riegel im Schnitt gemäß Figur 1. Erkennbar ist das vorgefertigte Gehäuse 2 mit seinen Kontaktkammern 3, in dem jeweils ein Kontaktpartner 9 eingesetzt ist, der am Ende des elektrischen Leiters 4 angeordnet und mit diesem elektrisch kontaktiert ist. Der gezeigte fertige Steckverbinder 1 weist schon als Dichtung die Spritzgussmasse 5 auf, wobei der Riegel 6 verhindert hat, daß die Spritzgussmasse 5 in die Kontaktkammern 3 und damit in den Kontaktbereich der Kontaktpartner 9 eindringt. Ebenso ist das Element 7 zur Lagefixierung der elektrischen Leiter 4 zueinander vorhanden. FIG. 5 shows a connector with a bolt according to the invention in section according to FIG. 1 , Visible is the prefabricated housing 2 with its contact chambers 3, in each of which a contact partner 9 is inserted, which is arranged at the end of the electrical conductor 4 and contacted with this electrically. The finished connector 1 shown already has the injection molding compound 5 as a seal, wherein the latch 6 has prevented that the injection molding compound 5 penetrates into the contact chambers 3 and thus into the contact region of the contact partner 9. Likewise, the element 7 for fixing the position of the electrical conductor 4 is present to each other.
