Description

Die Erfindung betrifft einen Steckverbinder und einen Gegensteckverbinder zur Herstellung einer elektrisch leitfähigen Verbindung.The invention relates to a connector and a mating connector for producing an electrically conductive connection.

Aus der EP 1 763 110 B1 ist ein Buchsenkontakt zur Herstellung einer elektrischen Steckverbindung bekannt. Ein Kontaktteil weist mindestens eine Kontaktlamelle auf, die federschenkelartig am Kontaktteil angeordnet ist. Die Kontaktlamellen laufen zunächst aufeinander zu und bilden im Kontaktierungsbereich Kontaktpunkte. Ein Steckkontakt wird über einen Öffnungsbereich in den Buchsenkontakt eingeführt. Durch das Einführen des Steckkontakts werden die Kontaktlamellen entgegen einer durch die federnde Anordnung wirkende Kontaktnormalkraft zum Auffedern gezwungen ist der jeweilige Kontaktpunkt der Kontaktlamellen mit dem Steckkontakt kontaktiert.From the EP 1 763 110 B1 is a socket contact for producing an electrical connector known. A contact part has at least one contact blade, which is arranged like a spring leg on the contact part. The contact blades initially converge and form contact points in the contacting region. A plug contact is inserted via an opening area in the socket contact. By inserting the plug contact, the contact blades are forced to spring against a force acting through the resilient arrangement normal contact force is the respective contact point of the contact blades contacted with the plug contact.

Es ist somit bekannt, dass während eines Steckvorgangs der zugehörige Kontaktpunkt über die gesamte Stecklänge eines Kontaktstifts reibt. Damit einher geht ein entsprechender Abrieb an der Kontaktstelle, was zwangsläufig zu einer Erhöhung des Durchgangswiderstandes der Steckverbindung führt. Umwelteinflüsse wie Schadgase, Feuchte, Wärme, etc. begünstigen darüber hinaus die Erosion der Kontaktstelle und des Kontaktstifts.It is thus known that during a plugging operation, the associated contact point rubs over the entire plug length of a contact pin. This is accompanied by a corresponding abrasion at the contact point, which inevitably leads to an increase in the contact resistance of the connector. Environmental influences such as noxious gases, humidity, heat, etc. also favor the erosion of the contact point and the contact pin.

Aufgabe der Erfindung ist es somit, die bekannten Kontaktsysteme zu verbessern.The object of the invention is thus to improve the known contact systems.

Die der Erfindung zu Grunde liegende Aufgabe wird durch einen Steckverbinder nach dem Anspruch 1 und einen Gegensteckverbinder nach dem Anspruch 6 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben. Für die Erfindung wichtige Merkmale finden sich ferner in der nachfolgenden Beschreibung und den in den Zeichnungen, wobei die Merkmale sowohl in Alleinstellung als auch in unterschiedlichen Kombinationen für die Erfindung wichtig sein können, ohne dass hierauf nochmals explizit hingewiesen wird.The object of the invention is achieved by a connector according to claim 1 and a mating connector according to claim 6. Advantageous developments are specified in the subclaims. For the invention important features can be found also in the following description and in the drawings, the features both alone and in different combinations for the invention may be important, without being explicitly referred to again.

Dadurch, dass ein Führungsmittel eines Steckverbinders derart ausgebildet und angeordnet ist, dass Kontaktstege einer Kontaktbuchse eines Gegensteckverbinders zur Herstellung einer elektrisch leitfähigen Verbindung in Richtung des Kontaktstifts führbar sind und den Kontaktstift zu einer elektrischen Kontaktierung reibschlüssig umgreifen, werden Bereiche der elektrischen Kontaktierung und Bereiche, an denen Abrieb entstehen kann, vorteilhaft entkoppelt. Durch dieses Auseinanderfallen der Bereiche zur elektrischen Kontaktierung und zur Führung der Kontaktbuchse kann vorteilhaft die Anzahl von Steckzyklen erhöht werden und die Widerstandsfähigkeit des Steckverbinders beziehungsweise des Gegensteckverbinders gegenüber Umwelteinflüssen wird vorteilhaft erhöht. Entsprechend ergibt sich über die Lebenszeit ein im Wesentlichen konstanter Kontaktübergangswiderstand, da der mögliche Abrieb im Bereich der Führung der Kontaktbuchse keinen Einfluss auf diesen hat. Darüber hinaus wird die Beständigkeit gegenüber Vibrationen, die auf die Steckverbindung wirken, stark erhöht. Vorteilhaft kann der Buchsenkontakt aus vergleichsweise weichem Crimpmaterial wie beispielsweise Kupfer gefertigt sein, da das Führungsmittel auf der Seite des Kontaktstiftes die nötige Anpresskraft zur Herstellung des Reibschlusses erzeugt.Characterized in that a guide means of a connector is designed and arranged such that contact webs of a contact socket of a mating connector for making an electrically conductive connection in the direction of the contact pin are feasible and engage around the contact pin to an electrical contact friction areas of electrical contact and areas to which can cause abrasion, advantageously decoupled. By this falling apart of the areas for electrical contact and for guiding the contact socket can advantageously the number of mating cycles be increased and the resistance of the connector or the mating connector to environmental influences is advantageously increased. Accordingly, a substantially constant contact resistance occurs over the lifetime, since the possible abrasion in the region of the guide of the contact socket has no influence on this. In addition, the resistance to vibration acting on the connector, greatly increased. Advantageously, the socket contact can be made of comparatively soft crimp material such as copper, since the guide means generates on the side of the contact pin the necessary contact force for the production of frictional engagement.

In einer vorteilhaften Ausführungsform ist der Kontaktstift entlang seiner Mittenlängsachse verschiebbar gelagert. Eine Druckfeder des Steckverbinders drückt den Kontaktstift in Steckrichtung. Damit kann vorteilhaft nach der Herstellung des Reibschlusses zwischen den Kontaktstegen und dem Kontaktstift der Kontaktstift eine Kontaktposition einnehmen, in der eine sichere elektrische Kontaktierung bei gleichzeitig minimiertem mögliche Abrieb im Bereich der elektrischen Kontaktierung ermöglicht wird. Dadurch, dass in der Kontaktposition die Haftreibung größer ist als die Federkraft oder gleich groß wie die Federkraft ist, wird vorteilhaft der Kontaktstift in der Kontaktbuchse eingeklemmt.In an advantageous embodiment, the contact pin is displaceably mounted along its central longitudinal axis. A compression spring of the connector presses the contact pin in the insertion direction. This can advantageously assume a contact position after the production of the frictional engagement between the contact webs and the contact pin of the contact pin, in which a secure electrical contact while minimizing possible abrasion in the electrical contact is made possible. The fact that in the contact position, the static friction is greater than the spring force or the same size as the spring force, the contact pin is advantageously clamped in the contact socket.

In einer vorteilhaften Ausführungsform ist das Führungsmittel als Ringfeder ausgebildet, wobei die Ringfeder im Wesentlichen koaxial zur Mittenlängsachse des Kontaktstifts angeordnet ist. Bei einer Zuführung der Kontaktstege der Kontaktbuchse werden die Kontaktstege durch die Ringfeder abgelenkt und in Richtung des Kontaktstifts gedrückt, wobei die nötige Anpresskraft der Kontaktstege auf den Kontaktstift zur Herstellung des Reibschlusses durch die Ringfeder erzeugt wird.In an advantageous embodiment, the guide means is designed as an annular spring, wherein the annular spring is arranged substantially coaxially to the central longitudinal axis of the contact pin. In a supply of the contact webs of the contact socket, the contact webs are deflected by the annular spring and in the direction of Pressed contact pin, wherein the necessary contact pressure of the contact webs is generated on the contact pin for producing the frictional engagement by the annular spring.

In einer vorteilhaften Ausführungsform weist das Führungsmittel einen Innendurchmesser auf, der kleiner ist als ein Außendurchmesser der zugeordneten Kontaktbuchse des Gegensteckverbinders. Dadurch kann vorteilhaft die Kontaktbuchse bis zum Führungsmittel ohne Reibung geführt werden. Zur Kontaktierung der Kontaktbuchse mit dem Kontaktstift führt der Innendurchmesser des Führungsmittels, der kleiner ist als der Außendurchmesser der zugeordneten Kontaktbuchse dazu, dass die Kontaktstege der Kontaktbuchse hin zu dem Kontaktstift geführt werden.In an advantageous embodiment, the guide means has an inner diameter which is smaller than an outer diameter of the associated contact socket of the mating connector. As a result, the contact bush can advantageously be guided to the guide means without friction. For contacting the contact socket with the contact pin, the inner diameter of the guide means, which is smaller than the outer diameter of the associated contact socket, causes the contact webs of the contact socket to be guided towards the contact pin.

In einer vorteilhaften Ausführungsform weist der Kontaktstift einen Außendurchmesser auf, der kleiner ist als ein Innendurchmesser der zugeordneten Kontaktbuchse des Gegensteckverbinders in nicht kontaktiertem Zustand. Auch in dieser Ausführungsform führt diese Dimensionierung dazu, dass das in einer Vorsteckposition die Kontaktbuchse im Wesentlichen ohne Reibung dem Kontaktstift zugeführt werden kann.In an advantageous embodiment, the contact pin has an outer diameter which is smaller than an inner diameter of the associated contact socket of the mating connector in the non-contacted state. In this embodiment as well, this dimensioning means that the contact socket can be supplied to the contact pin substantially without friction in a pre-insertion position.

The connector 2 comprises a guide means 4 and a contact pin 6, which are arranged in an insulating body 8. The connector 2 is constructed substantially rotationally symmetrical about a central longitudinal axis.

Der Kontaktstift 6 ist entlang der Mittenlängsachse 10 in dem Isolierkörper 8 verschiebbar gelagert. Eine Druckfeder 12, die sich entgegen einer Steckrichtung 14 des Steckverbinders 2 an einem zu dem Isolierkörper 8 feststehenden Abschnitt 16 abstützt, drückt den Kontaktstift 6 in die Steckrichtung 14 des Steckverbinders 2. Entgegen der Steckrichtung 14 ist in dem Bereich 18 des Kontaktstifts 6 eine elektrische Kontaktierung beispielsweise mit einem Kabel anordenbar. Ein Anschlagbereich 20 des Isolierkörpers 8 begrenzt gemeinsam mit einem entsprechenden Durchmesservorsprung 22 des Kontaktstifts 6 die Bewegung des Kontaktstifts 6 in die Steckrichtung 14.The contact pin 6 is slidably mounted along the central longitudinal axis 10 in the insulating body 8. A compression spring 12, which opposes a direction of insertion 14 of the Connector 2 is supported on a fixed to the insulating body 8 section 16, pushes the contact pin 6 in the insertion direction 14 of the connector 2. Contrary to the insertion direction 14 is in the region 18 of the contact pin 6, an electrical contact, for example, with a cable can be arranged. A stop region 20 of the insulating body 8, together with a corresponding diameter projection 22 of the contact pin 6, limits the movement of the contact pin 6 in the plugging direction 14.

Der Kontaktstift 6 befindet sich in einer Position, in der der Kontaktstift 6 nicht entgegen der Steckrichtung 14 kraftbeaufschlagt ist. In dieser Vorsteckposition des Kontaktstifts 6 erstreckt sich der Kontaktstift 6 vollständig durch das Führungsmittel 4.The contact pin 6 is in a position in which the contact pin 6 is not acted upon against the insertion direction 14. In this Vorsteckposition the contact pin 6, the contact pin 6 extends completely through the guide means 4th

In der Steckrichtung 14 weist der Kontaktstift 6 einen Außendurchmesser 24 auf. Der Bereich des Kontaktstifts 6 mit dem Außendurchmesser 24 ist gemeinsam mit dem Führungsmittel 4 in einem Aufnahmebereich 26 des Isolierkörpers 8 angeordnet.In the plugging direction 14, the contact pin 6 has an outer diameter 24. The region of the contact pin 6 with the outer diameter 24 is arranged together with the guide means 4 in a receiving region 26 of the insulating body 8.

Das Führungsmittel 4 ist in einer umlaufenden Innennut 28 des Aufnahmebereichs 26 angeordnet. Entgegen der Steckrichtung 14 des Steckverbinders 4 weist das Führungsmittel 4 eine Einführschräge 30 auf, die bis zu dem Innendurchmesser 32 des Führungsmittels 4 führt. Der Aufnahmebereich 26 des Isolierkörpers 8 selbst weist einen Innendurchmesser 34 auf. Das Führungsmittel 4 ist als Ringfeder ausgebildet und weist in Umfangsrichtung zumindest eine Unterbrechung auf, um die gewünschte Elastizität bereitzustellen. In Steckrichtung 14 verjüngt sich ein Außendurchmesser 36 auf einen Außendurchmesser 38.The guide means 4 is arranged in a circumferential inner groove 28 of the receiving region 26. Contrary to the insertion direction 14 of the connector 4, the guide means 4 has an insertion bevel 30, which leads up to the inner diameter 32 of the guide means 4.

In the insertion direction 14, an outer diameter 36 tapers to an outer diameter 38.

Figur 2 zeigt eine schematische Schnittdarstellung eines Gegensteckverbinders 40, der zur Anordnung an dem Steckverbinder 2 ausgebildet ist. Der Gegensteckverbinder 40 weist einen Isolierkörper 42 und eine Kontaktbuchse 44 auf, die in dem Isolierkörper 42 angeordnet ist. Ein Bereich 46 der Kontaktbuchse 44 dient zur elektrischen Kontaktierung, beispielsweise mit einem entsprechenden Kabel. Der Gegensteckverbinder 40 ist im Wesentlichen konzentrisch um eine Mittenlängsachse 48 aufgebaut. Die Kontaktbuchse 44 weist einen zu dem Isolierkörper 8 korrespondierenden Aufnahmebereich 50 auf.

The mating connector 40 is constructed substantially concentric about a central longitudinal axis 48. The contact socket 44 has a receiving area 50 corresponding to the insulating body 8.

In dem Aufnahmebereich 50 weist die Kontaktbuchse 44 von Schlitzen 52 unterbrochene Kontaktstege 54 auf, die vorzugsweise spiegelsymmetrisch zur Mittenlängsachse 48 angeordnet sind und sich im Wesentlichen parallel zur Mittenlängsachse 48 erstrecken. Die Kontaktstege 54 zeigen in eine Steckrichtung 56 des Gegensteckverbinders 40. Des Weiteren können sich gegenüberliegende Kontaktstege 54 aufeinander zu in Richtung der Mittenlängsachse 48 bewegt werden, was auch durch die Schlitze 52 ermöglicht wird. Die Kontaktbuchse 44 weist im Bereich der Kontaktstege 54 einen Innendurchmesser 58 und einen Außendurchmesser 60 auf. Zum distalen Ende hin weisen die Stege 54 der Kontaktbuchse 44 eine jeweilige zu der Einführschräge 30 korrespondierende Einführschräge 62 auf.In the receiving region 50, the contact bushing 44 of slots 52 broken contact webs 54, which are preferably arranged mirror-symmetrically to the central longitudinal axis 48 and extending substantially parallel to the central longitudinal axis 48. The contact webs 54 point in an insertion direction 56 of the mating connector 40. Furthermore, opposite contact webs 54 can be moved towards each other in the direction of the central longitudinal axis 48, which is also made possible by the slots 52. The contact bush 44 has an inner diameter 58 and an outer diameter 60 in the region of the contact webs 54. Towards the distal end, the webs 54 of the contact bush 44 have a respective insertion bevel 62 corresponding to the insertion bevel 30.

Bei Auftreffen der Einführschräge 62 auf die Einführschräge 30 werden die Kontaktstege 54 durch das Führungsmittel 4 in Richtung des Kontaktstifts 6 abgelenkt und das Führungsmittel 4 bringt die notwendige Anpresskraft auf, um die Kontaktstege 54 reibschlüssig mit dem Kontaktstift 6 elektrisch zu kontaktieren und den Kontaktstift 6 entgegen der Steckrichtung 14 zu drücken. Der Aufnahmebereich 50 weist einen Innendurchmesser 64 auf, der größer ist als der Außendurchmesser 38. Der Isolierkörper 42 weist einen Außendurchmesser 66 auf.Upon impact of the insertion bevel 62 on the insertion bevel 30, the contact webs 54 are deflected by the guide means 4 in the direction of the contact pin 6 and the guide means 4 brings the necessary contact force to frictionally contact the contact webs 54 with the contact pin 6 and the contact pin 6 against to press the plug-in direction 14. The receiving area 50 has an inner diameter 64 which is larger than the outer diameter 38. The insulating body 42 has an outer diameter 66.

Die Kontaktstege 54 weisen jeweils außenliegende Führungsabschnitte 68 auf, die bei einem Auftreffen auf das Führungsmittel 4 die Kontaktstege 54 jeweils in Richtung der Mittenlängsachse 48 hin zu dem Kontaktstift 6 drücken. Gleichzeitig werden innenliegende Kontaktabschnitte 70 auf den Kontaktstift 6 gedrückt und führen somit zu einer elektrischen Verbindung zwischen der Kontaktbuchse 44 und dem Kontaktstift 6. Die so separierten Führungsabschnitte 68 und Kontaktabschnitte 70 ermöglichen, dass ein Abrieb im Bereich der Führungsabschnitte 68 keinen nachteiligen Einfluss auf die Funktion der Kontaktabschnitte 70 hat.The contact webs 54 each have outer guide sections 68, which press the contact webs 54 toward the contact pin 6 in each case in the direction of the central longitudinal axis 48 when they impinge on the guide means 4. At the same time inner contact portions 70 are pressed onto the contact pin 6 and thus lead to an electrical connection between the contact socket 44 and the contact pin 6. The thus separated guide portions 68 and contact portions 70 allow abrasion in the region of the guide portions 68 no adverse effect on the function the contact portions 70 has.

Figur 3 zeigt eine schematische Schnittdarstellung des Steckverbinders 2 und des korrespondierenden Gegensteckverbinders 40 in einer Vorsteckposition. In dieser Vorsteckposition werden die Kontaktstege 54 im Wesentlichen parallel zueinander auf den Kontaktstift 6 zugeführt. Gleichzeitig greift der Isolierkörper 8 in den Aufnahmeraum 50 des Isolierkörpers 42 ein. Bis zu der gezeigten Vorsteckposition läuft der Kontaktstift 6 ohne Reibung und Kontaktierung zur Kontaktbuchse 44. Gleichzeitig befindet sich der Kontaktstift 6 bei Erreichen der gezeigten Vorsteckposition bereits innerhalb der Kontaktbuchse 44. FIG. 3 shows a schematic sectional view of the connector 2 and the corresponding mating connector 40 in a Vorsteckposition. In this Vorsteckposition the contact webs 54 are fed substantially parallel to each other on the contact pin 6. At the same time, the insulating body 8 engages in the receiving space 50 of the insulating body 42. Up to the shown Vorsteckposition the contact pin 6 runs without friction and contacting the contact socket 44. At the same time, the contact pin 6 is on reaching the shown Vorsteckposition already within the contact socket 44th

Figur 4 zeigt eine schematische Schnittansicht des Steckverbinders 2 und des Gegensteckverbinders 40 in einer Steckposition. Es ist gezeigt, wie sich die einzelnen Komponenten des Steckverbinders 2 und des Gegensteckverbinders 40 in einer Kontaktposition befinden.

Der Steckverbinder 2 und der Gegensteckverbinder 40 bilden ein Steckverbindersystem zum Herstellen der elektrisch leitfähigen Verbindung.The connector 2 and the mating connector 40 form a connector system for making the electrically conductive connection.

Ausgehend von der in Figur 3 gezeigten Vorsteckposition wurden in Figur 4 der Steckverbinder 2 und der Gegensteckverbinder 40 weiter aufeinander zu bewegt, was dazu führt, dass die Kontaktstege 54 in Richtung der Mittenlängsachse 10 beziehungsweise 48 geführt werden und damit dem Kontaktstift 6 reibschlüssig umgreifen. Durch diesen entstehenden Reibschluss drückt die Kontaktbuchse 44 den Kontaktstift 6 entgegen der Steckrichtung 14 und komprimiert somit die Druckfeder 12. Die Kontaktstege 54 umgreifen somit den Kontaktstift 6 reibschlüssig und kontaktieren den Kontaktstift 6 mittels der innenliegenden Kontaktabschnitte 70.Starting from the in FIG. 3 Vorsteckposition shown were in FIG. 4 the connector 2 and the mating connector 40 moves toward each other further, resulting in that the contact webs 54 are guided in the direction of the central longitudinal axis 10 and 48, and thus grip the contact pin 6 frictionally. As a result of this frictional engagement, the contact bushing 44 presses the contact pin 6 counter to the insertion direction 14 and thus compresses the compression spring 12. The contact webs 54 thus grip the contact pin 6 frictionally and contact the contact pin 6 by means of the inner contact sections 70.

In dem in den Figuren 1 bis 4 gezeigten Ausführungsbeispiel ist der Kontaktstift 6 beweglich in dem Steckverbinder 2 gelagert. Die Kontaktbuchse 44 ist hingegen feststehend in dem Gegensteckverbinder 40 angeordnet.In the in the FIGS. 1 to 4 Shown embodiment, the contact pin 6 is movably mounted in the connector 2. The contact socket 44, however, is fixedly arranged in the mating connector 40.
