Description

Die Erfindung betrifft einen Steckverbinder, der einen Kontaktträger aufweist, wobei in dem Kontaktträger zumindest ein Kontaktpartner angeordnet ist.The invention relates to a connector which has a contact carrier, at least one contact partner being arranged in the contact carrier.

Solche Steckverbinder, die einen männlichen und andererseits einen weiblichen Teil bilden, die zusammengesteckt eine Steckverbindung realisieren, sind grundsätzlich bekannt. In einem Kontaktträger des Steckverbinders, der in ein Steckverbindergehäuse eingesetzt werden kann, ist zumindest ein Kontaktpartner angeordnet, wobei der Kontaktpartner des einen Steckverbinders zusammen mit einem weiteren Kontaktpartner des Gegensteckverbinders im zusammengesteckten Zustand die Steckverbindung realisiert und damit eine elektrische Kontaktierung bewirkt. Solche Kontaktpartner sind als Kontaktstifte und damit korrespondierende Kontaktbuchsen ausgebildet, die jedoch nicht in allen Fällen die gewünschten Erfordernisse erfüllen, insbesondere nicht die ausreichende Stromstärke übertragen können.Such connectors, which form a male part and a female part on the other hand, which implement a plug connection when plugged together, are known in principle. At least one contact partner is arranged in a contact carrier of the plug connector, which can be inserted into a plug connector housing, the contact partner of the one plug connector realizing the plug connection together with another contact partner of the mating plug connector and thus effecting electrical contacting. Such contact partners are designed as contact pins and corresponding contact sockets, which, however, do not meet the desired requirements in all cases, in particular cannot transmit the sufficient current strength.

Druckschrift EP 1 164 666 A2 offenbart eine Buchse für Kraftfahrzeuge zur Aufnahme eines Steckers einer Vorrichtung für Kraftfahrzeuge zum elektrischen Verbinden mit einer Stromversorgung.pamphlet EP 1 164 666 A2 discloses a socket for motor vehicles for receiving a plug of a device for motor vehicles for electrical connection to a power supply.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen Steckverbinder bereit zu stellen, der auch rauhen Umgebungsbedingungen widersteht und mit dem die erforderliche Stromstärke übertragen werden kann bzw. die übertragenen Signale zuverlässig übertragen werden.The invention is therefore based on the object of providing a connector which can withstand harsh environmental conditions and with which the required current strength can be transmitted or the transmitted signals can be reliably transmitted.

Diese Aufgabe ist erfindungsgemäß durch einen Steckverbinder mit dem Merkmalen des Anspruchs 1 gelöst. Erfindungsgemäß weist der Steckverbinder einen Kontaktträger auf, wobei in dem Kontaktträger zumindest ein Kontaktpartner angeordnet ist und der zumindest eine Kontaktpartner auf einer Steckseite des Steckverbinders einen Kontaktring und davon ausgehend in Richtung eines Kabelabgangbereiches des Steckverbinders eine Kontaktfahne aufweist, wobei die Kontaktfahne in einer Kontaktkammer des Kontaktträgers angeordnet ist und eine Verprägung aufweist, die mit einem Hinterschnitt der Kontaktkammer des Kontaktträgers korrespondiert.This object is achieved by a connector with the features of claim 1. According to the invention, the connector has a contact carrier, wherein at least one contact partner is arranged in the contact carrier and the at least one contact partner has a contact ring on a plug side of the connector and, starting from there, in the direction of a cable outlet area of the connector, a contact lug, the contact lug in a contact chamber of the contact carrier is arranged and has an embossment which corresponds to an undercut of the contact chamber of the contact carrier.

Die Ausgestaltung des Kontaktpartners in einem Bereich als Kontaktring hat den Vorteil, dass mit einem entsprechend gestalteten Kontaktbereich des Gegensteckverbinders eine zuverlässige Kontaktierung im zusammengesteckten Zustand möglich ist, da eine insgesamt größere Kontaktfläche als bei normalen Kontaktstiften für die Kontaktierung zur Verfügung steht. Ein weiterer Vorteil der Ausgestaltung des Kontaktpartners mit seiner Kontaktfahne liegt darin, dass der Kontaktpartner mittels der Kontaktfahne sicher in der Kontaktkammer des Kontaktträgers festgelegt werden kann. Zur Unterstützung dieser Festlegung des Kontaktpartners in der Kontaktkammer ist eine Verprägung des Kontaktpartners vorgesehen, die mit einem Hinterschnitt der Kontaktkammer des Kontaktträgers korrespondiert, so dass dadurch der Kontaktpartner in der Kontaktkammer in seiner Lage eindeutig fixiert werden kann. Durch das Zusammenspiel von Verprägung der Kontaktfahne einerseits und dem im korrespondierenden Hinterschnitt der Kontaktkammer andererseits wird somit eine definierte Lage des Kontaktpartners in dem Kontaktträger erzielt, so dass Bewegungen des Kontaktpartners relativ zu dem Kontaktträger auch bei Einwirkung von äußeren Einflüssen, insbesondere Temperaturschwankungen und Vibrationen, ausgeschlossen sind.The design of the contact partner in an area as a contact ring has the advantage that reliable contacting in the mated state is possible with a correspondingly designed contact area of the mating connector, since an overall larger contact area is available for contacting than with normal contact pins. Another advantage of the design of the contact partner with his contact lug is that the contact partner can be securely fixed in the contact chamber of the contact carrier by means of the contact lug. To support this determination of the contact partner in the contact chamber, an embossing of the contact partner is provided, which corresponds to an undercut of the contact chamber of the contact carrier, so that the position of the contact partner in the contact chamber can thereby be clearly fixed. The interaction of the embossing of the contact lug on the one hand and that in the corresponding undercut of the contact chamber on the other hand thus achieves a defined position of the contact partner in the contact carrier, so that movements of the contact partner relative to the contact carrier even under the influence of external influences, in particular temperature fluctuations and vibrations, are excluded are.

Erfindungsgemäß weist die Kontaktfahne um die Verprägung herum, insbesondere parallel zu deren Längsseiten, eine Verbreiterung auf. Dadurch wird eine Versteifung der an sich schmalen und länglichen Ausgestaltung der Kontaktfahne erzielt, so dass dadurch die Steifheit der Kontaktfahne verbessert wird, was zu einer nochmals gesteigerten Stabilität und verbesserten Lagefixierung des Kontaktpartners in dem Kontaktträger führt.According to the invention, the contact lug has a widening around the embossing, in particular parallel to the long sides thereof. This results in a stiffening of the narrow and elongated configuration of the contact lug, so that the stiffness of the contact lug is improved, which leads to a further increased stability and improved position fixing of the contact partner in the contact carrier.

In Weiterbildung der Erfindung umfasst der Steckverbinder mehr als einen Kontaktpartner, wobei die Kontaktringe der Kontaktpartner koaxial und beabstandet zueinander in dem Kontaktträger angeordnet sind. Dadurch ist es möglich, mehr als einen Stromkreis mittels einer Steckverbindung zu realisieren, so dass z.B. mehrere Signale über den Steckverbinder übertragen werden können. Bei dieser Ausgestaltung ist es von besonderem Vorteil, dass jeder Kontaktpartner der mehreren Kontaktpartner die Verprägung in der Kontaktfahne aufweist, da auf Grund der erhöhten Stabilität des jeweiligen Kontaktpartners bei Einwirkung von äußeren Umgebungsbedingungen, insbesondere wie Temperaturschwankungen und Vibrationen, wirksam verhindert wird, dass die koaxial zueinander angeordneten Kontaktringe in Berührung kommen. Damit werden wirksam Kurzschlüsse zwischen den Kontaktpartnern ausgeschlossen. Außerdem führt die erhöhte Steifheit der Kontaktpartner, insbesondere der Kontaktfahnen, dazu, dass deren koaxial und beabstandet zueinander in dem Kontaktträger angeordnete Kontaktpartner näher zueinander angeordnet werden können, was zu einer erhöhten Kompaktheit der Bauweise des Steckverbinders führt.In a further development of the invention, the connector comprises more than one contact partner, the contact rings of the contact partners being arranged coaxially and at a distance from one another in the contact carrier. This makes it possible to implement more than one circuit using a plug connection, so that e.g. multiple signals can be transmitted via the connector. In this embodiment, it is particularly advantageous that each contact partner of the plurality of contact partners has the embossment in the contact tab, because due to the increased stability of the respective contact partner when exposed to external environmental conditions, in particular such as temperature fluctuations and vibrations, the coaxial is effectively prevented contact rings arranged to each other come into contact. This effectively prevents short circuits between the contact partners. In addition, the increased stiffness of the contact partners, in particular of the contact tabs, means that their contact partners, which are arranged coaxially and at a distance from one another in the contact carrier, can be arranged closer to one another, which leads to an increased compactness of the design of the connector.

In Weiterbildung der Erfindung ist der Kontaktpartner, oder auch die mehreren Kontaktpartner, im Presssitz in der Kontaktkammer angeordnet. Dies hat den Vorteil, dass der jeweilige Kontaktpartner in seiner zugehörigen Kontaktkammer einfach montiert werden kann, indem er manuell oder automatisiert in diese Kontaktkammer eingedrückt wird. Dieser Presssitz wird durch die Gestaltung der Kontaktfahne mit ihrer Verprägung und dem korrespondierenden Hinterschnitt der Kontaktkammer unterstützt.In a further development of the invention, the contact partner, or also the plurality of contact partners, is arranged in a press fit in the contact chamber. This has the advantage that the respective contact partner can be easily installed in its associated contact chamber by manually or automatically in this contact chamber is pushed in. This press fit is supported by the design of the contact lug with its embossing and the corresponding undercut of the contact chamber.

In Weiterbildung der Erfindung ist die Verprägung der Kontaktfahne zwischen dem Kontaktring und einem Kabelanschlussbereich vorgesehen. Das bedeutet, dass die Verprägung in einem sich länglich und schmal erstreckenden Bereich des Kontaktpartners vorgesehen ist. Durch die Anordnung an dieser Stelle wird in besonders vorteilhafter Weise die Steifheit des Kontaktpartners erhöht, insbesondere dann, wenn er in der Kontaktkammer mit dem dort vorhandenen korrespondierenden Hinterschnitt angeordnet ist. Der Kontaktpartner seinerseits wird in vorteilhafter Weise in einem Stanzbiege- und/oder Stanzrollverfahren hergestellt, so dass er insbesondere in vorteilhafter Weise in einem einfach auszuführenden Verfahren in großen Stückzahlen rationell hergestellt werden kann. An dem Kabelanschlussbereich wird vor oder nach der Anordnung des Kontaktpartners in dem Kontaktträger in geeigneter Weise ein elektrischer Leiter eines Kabels angebracht, beispielsweise durch Verlöten, Vercrimpen oder dergleichen.In a further development of the invention, the embossing of the contact tab between the contact ring and a cable connection area is provided. This means that the embossing is provided in an elongated and narrow area of the contact partner. The arrangement at this point increases the stiffness of the contact partner in a particularly advantageous manner, in particular when it is arranged in the contact chamber with the corresponding undercut there. The contact partner, for its part, is advantageously produced in a stamping and / or stamping and rolling process, so that it can be produced in large quantities in an advantageous manner, in an easy to carry out process. An electrical conductor of a cable is suitably attached to the cable connection area before or after the arrangement of the contact partner in the contact carrier, for example by soldering, crimping or the like.

Ein Ausführungsbeispiel eines erfindungsgemäßen Steckverbinders ist in den Figuren gezeigt und im Folgenden beschrieben.An embodiment of a connector according to the invention is shown in the figures and described below.

Die Figuren 1 bis 4 zeigen, soweit im Einzelnen dargestellt, einen Steckverbinder 1, der einen Kontaktträger 2 aufweist. Dieser Kontaktträger 2 ist beispielsweise in einem Kunststoffspritzgussverfahren hergestellt und wird in ein nicht näher bezeichnetes Steckverbindergehäuse des Steckverbinders 1 eingesetzt. Der Steckverbinder 1 weist eine Steckseite 3 auf, über die er mit einem hier nicht dargestellten Gegensteckverbinder zur Bildung einer Steckverbindung zusammengesteckt werden kann. Auf der der Steckseite 3 abgewandten Seite des Steckverbinders 1 befindet sich eine Kabelabgangsseite 4, über die der Steckverbinder 1 mit einen ein- oder mehradrigen Kabel verbunden ist.The Figures 1 to 4 show, as far as shown in detail, a connector 1 having a contact carrier 2. This contact carrier 2 is produced, for example, in a plastic injection molding process and is inserted into a connector housing of the connector 1, which is not described in more detail. The connector 1 has a plug side 3, via which it can be plugged together with a mating connector, not shown here, to form a plug connection. On the side facing away from the plug-in side 3 Connector 1 is a cable outlet side 4, via which the connector 1 is connected to a single or multi-core cable.

In Figur 2 ist gemäß dem Schnitt C-C der Figur 1 der Kontaktträger 2 gezeigt, wobei erkennbar ist, dass er Kontaktkammern 5 aufweist, in die jeweils ein Kontaktpartner 6 (Figur 3) einsetzbar ist. In Figur 2 ist dargestellt, dass in dem Kontaktträger 2 insgesamt drei Kontaktkammern 5 vorhanden sind, in die jeweils ein Kontaktpartner eingesetzt werden kann. Je nach Anwendungsfall des Steckverbinders 1 können auch mehr oder weniger als drei Kontaktkammern 5 vorhanden sein. In Figur 3 ist im Detail der Kontaktpartner 6 dargestellt, wobei dieser Kontaktpartner 6 einen Kontaktring 7 aufweist, von dem ausgehend eine längliche und schmale Kontaktfahne 8 einstückig oder angefügt vorhanden ist. Die Kontaktfahne 8 kann eine Verbreiterung 9 und/oder eine Verprägung 10 aufweisen. Die Verprägung 10 der Kontaktfahne 8 ist dabei in besonders vorteilhafter Weise zwischen dem Kontaktring 7 und einem Kabelanschlussbereich 12 vorgesehen. In Figur 4 ist das Detail D gemäß Figur 2 in vergrößerter Ansicht (Maßstab 10:1 in Bezug auf die Figur 2, Maße in Millimeter) dargestellt. Dabei ist erkennbar, dass die Kontaktkammer 5 in dem Kontaktträger 2 einen Hinterschnitt 11 aufweist, wobei die Form dieses Hinterschnitts 11 mit der Verbreiterung 9 bzw. der Verprägung 10 der Kontaktfahne 8 korrespondiert. Weiter ist erkennbar, dass auf Grund der Verprägung 10 die eine größere Oberfläche der Kontaktfahne an der Oberfläche der Kontaktkammer 5 zur Anlage kommt, so dass damit ein Spiel des Kontaktpartners 6 in seiner Kontaktkammer 5 ausgeschlossen ist. Zur Erhöhung dieses Effektes ist die Verbreiterung 9 vorgesehen, die somit längliche Fahnen bildet, die in einer Ausnehmung 13 rechts und/oder links des Hinterschnittes 11 der Kontaktkammer 5 (bei Betrachtung der Figur 4) zur Anlage kommen. Auf Grund der gewählten Dimensionen dieser Ausnehmung 13 rechts und/oder links von der Kontaktkammer 5 und deren längliche Erstreckung, die insbesondere der länglichen Erstreckung der Verbreiterung 9 entspricht, kann der Kontaktpartner 6 im Presssitz in der Kontaktkammer 5 festgelegt werden.In Figure 2 is the section according to section CC Figure 1 the contact carrier 2 is shown, wherein it can be seen that it has contact chambers 5, into each of which a contact partner 6 ( Figure 3 ) can be used. In Figure 2 it is shown that there are a total of three contact chambers 5 in the contact carrier 2, into each of which a contact partner can be inserted. Depending on the application of the connector 1, there may also be more or fewer than three contact chambers 5. In Figure 3 is shown in detail the contact partner 6, wherein this contact partner 6 has a contact ring 7, from which an elongated and narrow contact tab 8 is present in one piece or attached. The contact tab 8 can have a widening 9 and / or an embossing 10. The embossing 10 of the contact lug 8 is provided in a particularly advantageous manner between the contact ring 7 and a cable connection area 12. In Figure 4 is the detail D according to Figure 2 in an enlarged view (scale 10: 1 in relation to the Figure 2 , Dimensions in millimeters). It can be seen that the contact chamber 5 has an undercut 11 in the contact carrier 2, the shape of this undercut 11 corresponding to the widening 9 or the embossing 10 of the contact tab 8. It can also be seen that, due to the embossing 10, the larger surface of the contact lug comes into contact with the surface of the contact chamber 5, so that play of the contact partner 6 in its contact chamber 5 is thus ruled out. To increase this effect, the widening 9 is provided, which thus forms elongated flags, which are in a recess 13 on the right and / or left of the undercut 11 of the contact chamber 5 (when viewing the Figure 4 ) come to the plant. Due to the selected dimensions of this recess 13 to the right and / or left of the contact chamber 5 and its elongated extension, in particular the elongated extension of the Widening 9 corresponds, the contact partner 6 can be fixed in a press fit in the contact chamber 5.

Mit Blick auf die Figur 1 ist erkennbar, dass dort zumindest zwei Kontaktpartner 6 vorhanden sind, deren Kontaktringe 7 in axialer Ausrichtung des Steckverbinders 1 hintereinander angeordnet sind, wobei die Durchmesser der beiden Kontaktringe 7 derart geringfügig voneinander abweichen, dass bei Draufsicht auf die Steckseite 3 die Kontaktringe 7 koaxial und beabstandet zueinander in dem Kontaktträger angeordnet sind, jedoch eine Berührung untereinander ausgeschlossen ist, um Kurzschlüsse zu vermeiden. Während in Figur 1 dargestellt ist, dass die beiden Kontaktringe 7 (oder auch mehrere Kontaktringe) in axialer Richtung beabstandet voneinander angeordnet sind, kann es denkbar sein, dass die jeweiligen Kontaktringe in axialer Richtung nicht beabstandet zueinander angeordnet sind, sondern auf gleicher Höhe angeordnet sind, sich jedoch im Durchmesser voneinander unterscheiden, so dass sie auch in diesem Fall bei Draufsicht auf die Steckseite 3 koaxial zueinander angeordnet sind. Dabei ist der Innen- und Außendurchmesser des jeweiligen Kontaktringes 7 so zu wählen, dass er nicht nur mit dem anderen Kontaktring 7 in Berührung kommt (das heißt, beabstandet von ihm angeordnet ist), sondern dass auch die korrespondierenden Kontaktringe des Gegensteckverbinders beim Zusammenstecken in Eingriff mit dem jeweiligen Kontaktring des Steckverbinders 1 kommen, so dass die gewünschte elektrische Steckverbindung hergestellt wird, jedoch eine elektrische Verbindung zu den anderen Kontaktringen zur Vermeidung von Kurzschlüssen nicht erfolgt.With view on Figure 1 It can be seen that there are at least two contact partners 6, whose contact rings 7 are arranged one behind the other in the axial orientation of the connector 1, the diameters of the two contact rings 7 differing so slightly from one another that the top view of the plug side 3 coaxially and spaced the contact rings 7 are arranged to one another in the contact carrier, but contact with one another is excluded in order to avoid short circuits. While in Figure 1 it is shown that the two contact rings 7 (or also a plurality of contact rings) are arranged at a distance from one another in the axial direction, it may be conceivable that the respective contact rings are not arranged at a distance from one another in the axial direction, but are arranged at the same height, but in the Differentiate diameters from each other, so that in this case they are arranged coaxially to one another when the plug-in side 3 is viewed from above. The inner and outer diameter of the respective contact ring 7 is to be selected such that it not only comes into contact with the other contact ring 7 (that is to say is arranged at a distance from it), but also that the corresponding contact rings of the mating connector engage when plugged together come with the respective contact ring of the connector 1, so that the desired electrical connector is made, but an electrical connection to the other contact rings is not made to avoid short circuits.

Ebenfalls für die Erfindung wichtig: Mit der Bezugsziffer 13 ist rechts und/oder links von der Kontaktfahne 8 eine längliche Ausnehmung in der Kontaktkammer 5 bezeichnet. Die Ausnehmung 13 bildet ergänzend oder alternativ zu dem Hinterschnitt 11 ebenfalls einen Hinterschnitt, der mit der Verprägung 10, insbesondere mit der sich durch die Verprägung 10 ergebende Verbreiterung 9, der Kontaktfahne 8 korrespondiert. Die Kontaktkammer 5 ist, insbesondere mit den Ausnehmungen 13, von der Steckseite 3 für die Kontaktfahne 8 zugänglich, so dass diese aus Richtung der Steckseite 3 in die Kontaktkammer 5, beginnend mit dem Kabelanschlussbereich 12, eingeführt werden kann, bis die endgültige Lage des Kontaktpartners 6 (siehe Figur 1) erreicht ist. Dabei bewirken die Ausnehmungen 13 eine Führung des Kontaktpartners 6 beim Einführen in die Kontaktkammer 5 und dessen Festlegung dort, ohne dass sich ein Spiel zwischen diesen beiden Elementen ergibt (Presssitz). Ebenso weist die Kontaktfahne 8 im Querschnitt betrachtet einen bogenförmigen Querschnitt zur Erzielung einer Vorspannung auf, wenn sich die Kontaktfahne 8 in der Kontaktkammer 5 befindet.Also important for the invention: Reference number 13 denotes an elongated recess in the contact chamber 5 to the right and / or left of the contact lug 8. In addition or as an alternative to the undercut 11, the recess 13 likewise forms an undercut which is embossed with the embossing 10, in particular corresponds to the widening 9 resulting from the embossing 10, the contact tab 8. The contact chamber 5 is accessible, in particular with the recesses 13, from the plug-in side 3 for the contact lug 8, so that it can be inserted from the direction of the plug-in side 3 into the contact chamber 5, starting with the cable connection area 12, until the final position of the contact partner 6 (see Figure 1 ) is reached. The recesses 13 guide the contact partner 6 when it is introduced into the contact chamber 5 and fix it there without there being any play between these two elements (press fit). When viewed in cross section, the contact lug 8 likewise has an arcuate cross section to achieve a pretension when the contact lug 8 is in the contact chamber 5.

Der erfindungsgemäße Steckverbinder 1 wird in besonders vorteilhafter Weise in der Fahrzeugtechnik angewendet, insbesondere bei Fahrzeugen mit Verbrennungsmotoren zu deren Antrieb, so dass der Steckverbinder 1 beispielsweise im Motorraum eines solchen Fahrzeuges angeordnet wird. Da in einem solchen Motorraum sehr raue Umweltbedingungen, insbesondere Temperaturschwankungen, Verschmutzungen und Vibrationen, herrschen, ist die Anwendung des erfindungsgemäßen Steckverbinders 1 hier von besonderem Vorteil, da mit der beschriebenen Verprägung der Kontaktfahne und der damit erzielten Stabilität Kurzschlüsse wirksam vermieden werden. In besonders vorteilhafter Weise ist der Steckverbinder 1 zur Kontaktierung mit einem Sensor, z.B. ein Temperatur- oder Druckfühler, ausgebildet, wobei auch andere Arten von Sensoren oder auch beispielsweise Aktuatoren mit dem erfindungsgemäße Steckverbinder 1 verbunden werden können. Hierzu weist der jeweilige Sensor bzw. Aktuator auf seiner Steckseite ein Steckgesicht auf, das mit dem Steckgesicht auf der Steckseite 3 des Steckverbinders 1 korrespondiert.The connector 1 according to the invention is used in a particularly advantageous manner in vehicle technology, in particular in vehicles with internal combustion engines for driving them, so that the connector 1 is arranged, for example, in the engine compartment of such a vehicle. Since in such an engine compartment there are very harsh environmental conditions, in particular temperature fluctuations, dirt and vibrations, the use of the connector 1 according to the invention is of particular advantage here, since short circuits can be effectively avoided with the described embossing of the contact lug and the stability achieved thereby. In a particularly advantageous manner, the connector 1 is designed to make contact with a sensor, for example a temperature or pressure sensor, and other types of sensors or, for example, actuators can also be connected to the connector 1 according to the invention. For this purpose, the respective sensor or actuator has a plug face on its plug side, which corresponds to the plug face on plug side 3 of connector 1.
