Description

Die Erfindung betrifft einen Steckverbinder, ausgebildet als Stecker oder Kuppler einer daraus zusammensteckbaren Steckverbindung, gemäß den Merkmalen des Oberbegriffes des Patentsanspruches 1.The invention relates to a connector designed as a plug or coupler of a plug-in connector plugged together, according to the features of the preamble of patent claim 1.

Stecker oder Kuppler, insbesondere für die Anwendung in Automobilen, sind bekannt. Ein Ausführungsbeispiel eines bekannten Steckverbinders wird anhand der Figur 2, die den Stand der Technik dokumentiert, erläutert. Der in Figur 2 dargestellte Steckverbinder 10 weist ein Steckverbindergehäuse 11, insbesondere aus Kunststoff, auf. Das Steckverbindergehäuse 11 hat zumindest eine Kammer 12, im Regelfall mehrere Kammern, in die der Endbereich einer Leitung 13 eingeführt wird. Dabei ist der Querschnitt der Kammer 12 größer als der Querschnitt der Leitung 13, so dass dazwischen ein Spiel möglich ist. Im Endbereich der Leitung 13 ist an dessen elektrischem Leiter ein Kontaktpartner 14 angeschlagen, insbesondere mittels eine Crimpverbindung 15. Eine Isolierung zur Herstellung einer Längswasserdichtigkeit zwischen dem Kontaktpartner 14 und der Leitung 13 erfolgt über einen Isolationscrimp 16. Um zu verhindern, dass sich der Kontaktpartner 14 wieder aus der Kammer 12 nach seinem dortigen Einsetzen herausbewegt, ist eine auch Primärverriegelung genannte Festlegung des Kontaktpartners 14 in dem Steckverbindergehäuse 11 vorgesehen. Diese erfolgt über eine oder mehrere Laschen 17, die federnd ausgebildet und Bestandteil des Kontaktpartners 14 sind. Diese Laschen 17 werden beim Einsetzen des Kontaktpartners 14 in die Kammer 12 zusammengedrückt und spreizen sich, wenn der Kontaktpartner 14 seine Endlage in dem Steckverbindergehäuse 11 erreicht hat.Plugs or couplers, especially for use in automobiles, are known. An embodiment of a known connector will be explained with reference to Figure 2, which documents the prior art. The connector 10 shown in Figure 2 has a connector housing 11, in particular made of plastic, on. The connector housing 11 has at least one chamber 12, as a rule a plurality of chambers into which the end region of a line 13 is introduced. In this case, the cross section of the chamber 12 is greater than the cross section of the conduit 13, so that between a game is possible. In the end region of the line 13, a contact partner 14 is struck on the electrical conductor, in particular by means of a crimp connection 15. An insulation for producing a longitudinal water-tightness between the contact partner 14 and the line 13 via an insulation crimp 16. To prevent the contact partner 14th moved back out of the chamber 12 after its local insertion, a primary locking also called down the contact partner 14 is provided in the connector housing 11. This is done via one or more tabs 17 which are resilient and part of the contact partner 14. These tabs 17 are compressed upon insertion of the contact partner 14 in the chamber 12 and spread apart when the contact partner 14 has reached its end position in the connector housing 11.

Der somit fertige Steckverbinder 10 weist noch eine Gehäuseöffnung 18 zur Aufnahme eines komplementären Gegensteckverbinders auf, in die der Kontaktpartner des Gegensteckverbinders einsetzbar ist. Die Primärverriegelung des Kontaktpartners 14 in der Kammer 12 des Steckverbindergehäuses 11 verhindert zwar, dass sich der Kontaktpartner 14 grundsätzlich aus dem Steckverbindergehäuse 11 herausbewegen kann. Allerdings wird bei diesem Stand der Technik nicht verhindert, dass sich der Kontaktpartner 14 innerhalb der Kammer 12 noch relativ zu dem Steckverbindergehäuse 11 bewegen kann, insbesondere in axialer Richtung. Solche Bewegungen werden hervorgerufen durch Zug- und Druckbeanspruchungen der Leitung 13, Vibrationen der Umgebung, in der der Steckverbinder 10 eingesetzt wird, Temperaturschwankungen und dergleichen. Zur Beseitigung der Zug- und Druckbeanspruchungen auf die Leitung 13 ist zwar schon daran gedacht worden, durch entsprechende Maßnahmen (auch Zugentlastung genannt) diese Beanspruchungen zu beseitigen. Dadurch wird aber nach wie vor nicht verhindert, dass Vibrationseinleitungen von der Leitung 13 bis zur Gehäuseöffnung 18 sowohl auf den Kontaktpartner 14 als auch dessen komplementären Kontaktpartner des Gegensteckverbinders übertragen werden, was zu Reibkorrosionen und Oberflächenverschleiß und somit zu Widerstandserhöhungen und möglichen Kontaktunterbrechungen führt. Weiterhin kann es in nachteiliger Weise bei diesen bekannten Steckverbindern durch die angeschlagene Leitung 13 zu Zwangsverkantungen des Kontaktpartners 14 innerhalb der Kammer 12 kommen, welche sich wiederum schädigend und nachteilig auf die Gehäuseöffnung 18 auswirken.The thus finished connector 10 still has a housing opening 18 for receiving a complementary mating connector, in which the contact partner of the mating connector can be used. Although the primary locking of the contact partner 14 in the chamber 12 of the connector housing 11 prevents that the contact partner 14 can move out of the connector housing 11 in principle. However, in this prior art, it is not prevented that the contact partner 14 within the chamber 12 can still move relative to the connector housing 11, in particular in the axial direction. Such movements are caused by tensile and compressive stresses of the conduit 13, vibrations of the environment in which the connector 10 is used, temperature fluctuations and the like. To eliminate the tensile and compressive stresses on the line 13 while it has been thought already, by appropriate measures (also called strain relief) to eliminate these stresses. However, this still does not prevent vibration inlets from the line 13 to the housing opening 18 being transmitted both to the contact partner 14 and to its complementary contact partner of the mating connector, which leads to fretting corrosion and surface wear and thus to resistance increases and possible contact interruptions. Furthermore, it may be disadvantageous in these known connectors by the broken line 13 to Zwangsverkantungen of the contact partner 14 within the chamber 12, which in turn have harmful and adversely affect the housing opening 18.

Eine andere Ausführungsform eines Steckverbinders ist aus der DE 199 48 037 A1 bekannt. Der Vorteil dieser bekannten Steckverbindung ist die Vermeidung eines Kontaktpartners, der am Ende des elektrischen Leiters der Leitung angeschlagen wird. Dazu ist es vorgesehen, dass zur Aufnahme der Steckkräfte beim Zusammenstecken von Stecker und Kuppler sowohl der Endbereich der elektrischen Leitung als auch der freigelegte elektrische Leiter durch das Steckverbindergehäuse festgelegt werden. In gewisser Weise wird durch die Ausführung gemäß Figur 1 der DE 199 48 037 A1 schon eine Zugentlastung der Leitung dadurch erzielt, dass diese von dem Steckverbindergehäuse umgeben, insbesondere umspritzt ist. Eine solche Konstruktion ist allerdings äußerst aufwändig in der Herstellung, da bei dem Umspritzvorgang dafür Sorge getragen werden muss, dass einerseits der Endbereich der Leitung vollständig mit Kunststoff umspritzt wird, wohingegen andererseits der freigelegte elektrische Leiter nur teilweise mit dem Kunststoff des Steckverbindergehäuses umspritzt werden darf, da er einerseits in dem Steckverbindergehäuse ebenfalls festgelegt werden muss, andererseits ein Teil von ihm aber auch frei bleiben muss, damit eine elektrische Kontaktierung mit dem komplementären Endbereich des elektrischen Leiters des Kupplers erfolgen kann. Eine solche Ausführungsform eines Steckverbinders lässt sich nur mit sehr großem Aufwand realisieren, da die Abstimmung beim Spritzgussverfahren, insbesondere bei mehrpoligen Steckverbindern, extrem aufwändig und damit äußerst kostenintensiv ist.Another embodiment of a connector is from the DE 199 48 037 A1 known. The advantage of this known connector is the avoidance of a contact partner who is struck at the end of the electrical conductor of the line. For this purpose, it is provided that for receiving the insertion forces when mating plug and coupler, both the end portion of the electrical line and the exposed electrical conductor are defined by the connector housing. In some ways, the embodiment according to FIG DE 199 48 037 A1 already achieved a strain relief of the line characterized in that they are surrounded by the connector housing, is overmoulded in particular. However, such a construction is extremely complex to manufacture, since in the extrusion process must be taken to ensure that on the one hand the end of the line is completely encapsulated in plastic, whereas on the other hand, the exposed electrical conductor may only be partially encapsulated with the plastic of the connector housing, on the one hand because it must also be fixed in the connector housing, on the other hand, a part of it must also remain free, so that an electrical contact with the complementary end portion of the electrical conductor of the coupler can take place. Such an embodiment of a connector can be realized only with great effort, since the vote in the injection molding process, especially in multi-pin connectors, extremely complex and thus extremely expensive.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen Steckverbinder bereit zu stellen, der die eingangs geschilderten Nachteile vermeidet, der insbesondere bei der Serienherstellung (Großserie) eine kostengünstige und konfektionierbare Lösung darstellt, um die Fehlermöglichkeiten, die bisher bekannt sind (insbesondere Verschleiß und Kontaktunterbrechung), zu beseitigen.The invention is therefore based on the object to provide a connector that avoids the disadvantages described above, which is a cost-effective and customizable solution, especially in the series production (mass production) to the error possibilities that are known so far (in particular wear and break contact ), to eliminate.

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

Erfindungsgemäß sind Mittel zur spielfreien Lagefixierung des Endbereiches der Leitung innerhalb der Kammer an dem Steckverbindergehäuse vorgesehen, um den elektrischen Leiter von auf die Leitung wirkenden Kräften zu entkoppeln. Das bedeutet, dass das Steckverbindergehäuse nicht mehr direkt um den Endbereich der Leitung herum angespritzt wird, sondern diese Mittel als zusätzliches Bauteil oder als zusätzliche Bauteile in die Kammer einsetzbar sind und/oder die Mittel an dem Steckverbindergehäuse, das ein- oder mehrteilig ausgebildet ist, angeformt sind. Dadurch ist bei der Herstellung des Steckverbinders kein direktes Zusammenspiel zwischen der Umspritzung des Steckverbindergehäuses und dem Endbereich der Leitung erforderlich, so dass eine wesentlich einfachere und unkompliziertere Abstimmung der beteiligten Bauteile aufeinander möglich ist, aus der eine deutliche Kostenreduzierung resultiert. So können beispielsweise das ein- oder mehrteilige Steckverbindergehäuse hergestellt und auf die bekannten geometrischen Formen der elektrischen Leitung (Querschnittsform bzw. Durchmesser) abgestimmt werden, ohne dass die Leitung bei der Herstellung des Steckverbindergehäuses schon in die Spritzgussform eingelegt werden muss. Gleiches gilt für den freigelegten elektrischen Leiter der Leitung, der schon vor der Montage der Leitung in dem Steckverbindergehäuse konfektioniert werden kann, d.h., entweder selber als Kontaktpartner ausgebildet wird oder ein zusätzlicher Kontaktpartner an dem elektrischen Leiter angeschlagen wird. Insbesondere die Ausgestaltung der Mittel zur spielfreien Lagefixierung des Endbereiches der Leitung als separates Bauteil (ein- oder mehrteilig) hat den Vorteil, dass diese Mittel optimal auf den Querschnitt der Kammer und den Querschnitt der Leitung sowie deren axiale Erstreckung abgestimmt werden können. Diese Mittel werden dann beispielsweise nach Herstellung des Steckverbindergehäuses in die Kammer eingesetzt, wobei anschließend die Montage der elektrischen Leitung (mit oder ohne Kontaktpartner) erfolgt. Alternativ dazu ist es denkbar, dass die Mittel auf dem Endbereich der elektrischen Leitung montiert und diese Einheit in die Kammer des Steckverbindergehäuses eingeführt wird.According to the invention means are provided for play-free position fixing of the end portion of the conduit within the chamber to the connector housing to decouple the electrical conductor of forces acting on the line. This means that the connector housing is no longer molded directly around the end region of the line, but these means can be inserted as an additional component or as additional components in the chamber and / or the means on the connector housing, which is formed in one or more parts, are formed. As a result, in the manufacture of the connector no direct interaction between the encapsulation of the connector housing and the end portion of the line is required, so that a much simpler and less complicated vote of the participating components is possible, resulting in a significant cost reduction. For example, the one-piece or multi-part connector housing manufactured and matched to the known geometric shapes of the electrical line (cross-sectional shape or diameter), without the line in the production of the connector housing must be inserted into the injection mold. The same applies to the exposed electrical conductor of the line, which can be assembled in the connector housing before mounting the cable, ie, either itself is formed as a contact partner or an additional contact partner is posted to the electrical conductor. In particular, the design of the means for play-free position fixation of the end portion of the line as a separate component (one or more parts) has the advantage that these means can be optimally adapted to the cross section of the chamber and the cross section of the line and its axial extent. These means are then used for example after production of the connector housing in the chamber, wherein subsequently the assembly of the electrical line (with or without contact partner) takes place. Alternatively, it is conceivable that the means be mounted on the end portion of the electrical lead and that unit be inserted into the chamber of the connector housing.

In Weiterbildung der Erfindung sind die Mittel zur Lagefixierung kraftschlüssig und/oder formschlüssig ausgebildet. Ein Kraftschluss wird beispielsweise dadurch hergestellt, dass der Außenmantel der Leitung mit der Innenkontur der Kammer verklebt wird. Ein Formschluss der Verbindung zwischen dem Außenmantel der Leitung und der Innenkontur der Kammer wird beispielsweise durch einen Press- oder Quetschvorgang realisiert, wozu beispielsweise die Innenkontur der Kammer quer zu der axialen Erstreckung der Leitung Rippen aufweisen, die einen Querschnitt bilden, der kleiner ist als der Querschnitt der Leitung, so dass beim Einführen der Leitung über diese Rippen hinweg oder bei einem Zusammensetzen von zumindest zwei Teilen des mehrteiligen Steckverbindergehäuses die äußeren Konturen der Rippen auf den Außenmantel drücken und diesen spielfrei innerhalb des Steckverbindergehäuses in ihrer Lage fixieren, so dass der Kontaktbereich von Schwingungen, Vibrationen und sonstigen Bewegungen entkoppelt ist. Es kann auch daran gedacht werden, die Mittel zur spielfreien Lagefixierung aus einem elastisch verformbaren Material herzustellen, dessen Querschnitt zur Aufnahme der Leitung kleiner ist als der Querschnitt der Leitung und dessen Querschnitt zum Einsetzen in die Kammer größer ist, als der Querschnitt der Kammer, an dem die Mittel eingesetzt werden. Dadurch ergibt sich auf Grund einer Quetschung des elastisch verformbaren Materials eine formschlüssige Lagefixierung.In a further development of the invention, the means for fixing the position are formed positively and / or positively. A frictional connection is produced, for example, in that the outer casing of the line is glued to the inner contour of the chamber. A positive connection of the connection between the outer jacket of the conduit and the inner contour of the chamber is realized, for example, by a pressing or squeezing operation, for which purpose, for example, the inner contour of the chamber has ribs transverse to the axial extension of the conduit, forming ribs which are smaller than the cross section Cross-section of the line, so that when inserting the line over these ribs away or when assembling at least two parts of the multi-part connector housing press the outer contours of the ribs on the outer shell and fix this clearance within the connector housing in position, so that the contact area of Vibrations, vibrations and other movements is decoupled. It can also be thought to produce the means for play-free position fixing of an elastically deformable material whose Cross section for receiving the conduit is smaller than the cross section of the conduit and whose cross section for insertion into the chamber is greater than the cross section of the chamber on which the means are used. This results in a positive positional fixation due to a pinching of the elastically deformable material.

Insgesamt bietet die Erfindung also den Vorteil, dass die Lagefixierung der Leitung, insbesondere dessen Endbereich, im Steckverbindergehäuse so gewählt werden kann, dass eine Vibrationseinleitung über die elektrische Leitung bis in den Kontaktierungsbereich verhindert wird. Dies wird erreicht durch die spielfreie Lagefixierung der Leitung in dem ein- oder mehrteiligen Steckverbindergehäuse, insbesondere aus Kunststoff, so dass die Kontaktierungszone entkoppelt wird. Gleichzeitig wird auch der Vorteil, insbesondere durch separate Mittel zur spielfreien Lagefixierung, erreicht, dass die Geometrien der einzelnen beteiligten Elemente wesentlich besser aufeinander abgestimmt werden können, was zu einer vereinfachten und damit kostenreduzierten Herstellung von Steckverbindern mit deutlich verbesserten elektrischen Eigenschaften (insbesondere Verhinderung von Reibkorrosionen und Oberflächenverschleiß und damit Reduzierung von Übergangswiderstandserhöhungen und Vermeidung von Kontaktunterbrechungen) führt.Overall, the invention thus offers the advantage that the positional fixing of the line, in particular its end region, can be selected in the connector housing so that a vibration introduction via the electrical line is prevented up to the contacting region. This is achieved by the play-free fixing of the position of the line in the one- or multi-part connector housing, in particular made of plastic, so that the contacting zone is decoupled. At the same time, the advantage, in particular by separate means for backlash-free fixing, achieved that the geometries of the individual elements involved can be much better coordinated, resulting in a simplified and thus cost-reduced production of connectors with significantly improved electrical properties (especially prevention of Reibkorrosionen and surface wear and thus reduction of contact resistance increases and avoidance of contact interruptions) leads.

Besonders vorteilhaft ist die Anwendung der Erfindung in Automobilen, da hier rauhe Umgebungsbedingungen herrschen und weiterhin eine hohe Teilevielt vermieden werden soll. Außerdem muss die Steckverbindung robust bei gleichzeitig hoher Kontaktsicherheit sein. Daneben ist ein weiteres Anwendungsgebiet in hochvibrationsbelasteten Steckverbindungen für Industriesteckverbinder, insbesondere in der Produktions- oder Verfahrenstechnik, zu sehen. Diese Aufzählung ist jedoch nicht abschließend.Particularly advantageous is the application of the invention in automobiles, since harsh environmental conditions prevail here and furthermore a high proportion should be avoided to a great extent. In addition, the connector must be robust while maintaining high contact reliability. In addition, another field of application in high-vibration loaded connectors for industrial connectors, especially in production or process engineering, can be seen. However, this list is not exhaustive.

Ein Ausführungsbeispiel eines erfindungsgemäßen Steckverbinders, auf das die Erfindung jedoch nicht beschränkt ist, ist im Folgenden beschrieben und an Hand der Figuren erläutert.An embodiment of a connector according to the invention, to which the invention is not limited, is described below and explained with reference to the figures.

Diese Mittel 9 bewirken in vorteilhafter Weise, dass das Ende des elektrischen Leiters 5 oder ein daran angeschlagener Kontaktpartner und im zusammengesteckten Zustand auch der Gegensteckverbinder 8 (bzw. dessen Kontaktpartner) schwingungsentkoppelt sind, um die geschilderten Nachteile zu vermeiden.Figure 1 shows, as far as shown in detail, a connector 1, which is mated with a complementary coupler to a connector. The connector 1 has a connector housing 2, in particular a plastic housing. In the connector housing 2 is a chamber 3 or a plurality of chambers 3 are arranged (in a row or more rows) into which an end portion of a conduit 4 is inserted. The line 4 may be round, flat or other lines. The line 4 has at its end an exposed electrical conductor 5, which may also be a flat or round conductor (wire or stranded wire). The electrical conductor 5 is formed in its end region as a contact partner or at this a not shown here contact partner is arranged. The line 4 has an outer casing 6, in particular made of plastic. The connector housing 2 has the front side, emerging from the chamber 3, a contact zone 7, which is designed to receive a mating connector 8 (or its contact partner). The end of the line 4 is fixed in the inventive manner via means 9 clearance within the chamber 3 to the connector housing 2 in its position, the means 9 are formed positively and / or positively acting. These means 9 effect in an advantageous manner that the end of the electrical conductor 5 or an attached contact partner and in the assembled state and the mating connector 8 (or its contact partner) are vibration decoupled to avoid the disadvantages.

In vorteilhafter Weise sind die Mittel 9 in Bezug auf die Leitung 4 und das Steckverbindergehäuse 2 als ein ein- oder mehrteiliges separates Bauteil ausgebildet, können alternativ aber auch Bestandteil des Außenmantels 6 der Leitung 4 und/oder Bestandteil der Kammer 3 des Steckverbindergehäuses 2 sein.Advantageously, the means 9 are formed with respect to the line 4 and the connector housing 2 as a single or multi-part separate component, but may alternatively also be part of the outer jacket 6 of Line 4 and / or part of the chamber 3 of the connector housing 2 be.

Zusammenfassend bietet die Erfindung also den Vorteil, dass durch die form- und/oder kraftschlüssige Trennung der Kontaktzone 7 von der Fixierung der Leitung 4, den Mitteln 9 zu dem Steckverbindergehäuse 2 den Vorteil, dass die Schwingungseinleitung von der Leitung 4 bis in die Kontaktzone 7 nahezu ausgeschlossen oder vollständig eliminiert wird und damit der Oberflächenverschleiß der Kontaktpartner weitgehend verhindert wird, was wiederum zu einer deutlich größeren Zuverlässigkeit der Kontaktierung der Steckverbinder und deren Lebensdauer führt. Wird eine solche Konstruktion gewählt, dass der elektrische Leiter 5 an dem Steckverbindergehäuse 2 festliegt, lassen sich sehr hohe Kontaktnormalkräfte (vorzugsweise größer 10 Newton) realisieren, so dass dadurch eine kostengünstige, gewichtsreduzierte und zuverlässige Steckverbindung herstellbar ist, welche sowohl als gedichtete als auch ungedichtete Variante auf einfache Art und Weise und vor allen Dingen frei konfektionierbar realisierbar ist.In summary, the invention thus provides the advantage that the positive and / or non-positive separation of the contact zone 7 from the fixation of the line 4, the means 9 to the connector housing 2 has the advantage that the vibration introduction from the line 4 to the contact zone. 7 almost eliminated or completely eliminated and thus the surface wear of the contact partners is largely prevented, which in turn leads to a much greater reliability of the contact of the connector and its life. If such a construction is chosen so that the electrical conductor 5 is fixed to the connector housing 2, very high contact normal forces (preferably greater than 10 Newton) can be realized, thereby making it possible to produce a cost-effective, weight-reduced and reliable connector which is both sealed and unsealed Variant in a simple manner and, above all, is freely customizable feasible.
