Description

Die Erfindung betrifft einen Buchsenkontakt zur Herstellung einer elektrischen Steckverbindung, bestehend im Wesentlichen aus einem Anschlussteil für die Aufnahme eines elektrischen Leiters und einem Kontaktteil für die Kontaktierung eines einführbaren Steckkontakts in einen Kontaktierungsbereich, wobei im Kontaktierungsbereich federschenkelartig mindestens eine Kontaktlamelle mit mindestens einem an der Kontaktlamelle angeordneten Kontaktpunkt vorgesehen ist und dieser Kontaktpunkt eine elektrische Verbindung mit dem Steckkontakt herstellt.The invention relates to a socket contact for producing an electrical plug connection, consisting essentially of a connection part for receiving an electrical conductor and a contact part for contacting an insertable plug contact in a contacting region, wherein arranged in the contact area spring leg at least one contact blade with at least one on the contact blade Contact point is provided and this contact point establishes an electrical connection with the plug contact.

Stand der TechnikState of the art

Kontaktsysteme mit Buchsenkontakten der vorstehenden Art sind in vielfältigen Ausführungen bekannt. Solche Steckverbindungen bestehen aus einer Vielzahl von Buchsenkontakten, die in Steckergehäusen angeordnet sind, wobei zur Herstellung einer elektrischen Steckverbindung messerartige oder pinartige Ausbildungen von Steckkontakten, ebenfalls in Gehäusen angeordnet, in den Buchsenkontakt eindringen und dort mit Kontaktlamellen bzw. mit deren Kontaktpunkten kontaktieren. Dabei wird mindestens an diesem einen Kontaktpunkt mit einer hinreichend großen Kraft, der sogenannten Kontaktnormalkraft, die Kontaktlamelle auf die Oberfläche des Steckkontakts derart gedrückt, dass mögliche Fremdschichten auf den metallischen Oberflächen sicher durchdrückt werden und ein sicherer elektrischer Kontakt zustande kommt.Contact systems with female contacts of the above type are known in many designs. Such connectors consist of a plurality of socket contacts, which are arranged in connector housings, wherein knife-like or pin-like configurations of plug contacts, also arranged in housings, penetrate into the socket contact and make contact with contact blades or with their contact points for the production of an electrical plug connection. In this case, at least at this one contact point with a sufficiently large force, the so-called contact normal force, the contact blade pressed on the surface of the plug contact such that possible foreign layers are securely pushed through the metallic surfaces and a secure electrical contact is made.

Eine funktionsgerechte Konstruktion einer solchen Steckverbindung zeichnet sich unter anderem dadurch aus, dass die Zahl, Form und Lage der Kontaktpunkte sowie die wirkenden Kontaktnormalkräfte auf die elektrischen und tribologischen Anforderungen abgestimmt sind. Durch die große Zahl von Toleranzen und Passungen, die bei der Kontaktierung von Kontakt und Gegenkontakt im realen Einsatzfall zum Tragen kommen, muss jedoch davon ausgegangen werden, dass die realen Kontaktverhältnisse mehrfach statisch überbestimmt sind, wodurch unter Umständen einzelne Kontaktpunkte überhöhte, andere Kontaktpunkte hingegen unzureichende geringe Kontaktnormalkräfte erfahren können. Bei Steckverbindungen, bei denen hohe Stromtragfähigkeit Voraussetzung ist, kann ein solcher "Verlust" eines oder mehrerer Kontaktpunkte unter Umständen nicht vollständig durch andere Kontaktpunkte kompensiert werden. Die Folge davon ist, dass aufgrund von Widerstandsverlusten es zu einem verstärkten thermischen Verschleiß kommt.A functional design of such a connector is characterized inter alia by the fact that the number, shape and position of the contact points and the acting contact normal forces are matched to the electrical and tribological requirements. Due to the large number of tolerances and fits that come into effect when contacting contacts and mating contacts in real applications, however, it must be assumed that the real contact conditions are multiply statically over-determined, which may result in individual contact points being increased, while other contact points being insufficient can experience low contact normal forces. For connectors where high current carrying capacity is required, such a "loss" of one or more contact points may not be fully compensated by other contact points. The consequence of this is that due to resistance losses it comes to increased thermal wear.

Ferner sind solche Buchsenkontaktsysteme bekannt, bei denen die Kontaktpunkte gegenüber anordnet sind und den Steckkontakt zwischen sich einschließen, um die Wirkung der erwähnten Fertigungstoleranzen zu kompensieren. Bei hohen Stromtragfähigkeitsanforderungen und hinreichend breiten Steckkontakten werden weitere Steckkontakte mechanisch entkoppelter Kontaktlamellen daneben angeordnet. So ist auch aus der DE 195 36 500 C2 ein Buchsenkontakt bekannt, der ein Anschlussteil sowie ein Kontaktteil mit Federschenkelbasis und von dieser ausgehende Federschenkel umfasst. Um eine höhere Kontaktsicherheit, insbesondere für breite Steckkontakte zu gewährleisten, wird hierin vorgeschlagen, mehrere Federschenkel in der Ausbildung von Kontaktlamellen, die sich von dem Übergang des Anschlussteils zu dem Kontaktteil in den Öffnungsbereich des Buchsenkontakts erstrecken senkrecht zur Steckrichtung des Steckkontakts, d.h. nebeneinander, anzuordnen.Furthermore, such socket contact systems are known in which the contact points are arranged opposite and include the plug contact between them to compensate for the effect of said manufacturing tolerances. At high current carrying capacity requirements and sufficiently wide plug contacts further plug contacts mechanically decoupled contact blades are arranged next to it. So is also from the DE 195 36 500 C2 a socket contact known, which comprises a connection part and a contact part with spring leg base and outgoing therefrom spring leg. In order to ensure a higher contact reliability, in particular for wide plug contacts, it is proposed herein, a plurality of spring legs in the formation of contact blades extending from the transition of the connecting part to the contact part in the opening portion of the socket contact perpendicular to the plugging direction of the plug contact, ie side by side to arrange ,

Gemäß dem Stand der Technik sind Buchsenkontakte mit Kontaktlamellen in der Ausbildung bekannt, dass jede Kontaktlamelle einen Kontaktpunkt trägt. Dabei ist dieser Kontaktpunkt gegenüber den übrigen Kontaktlamellen mechanisch entkoppelt.According to the prior art socket contacts are known with contact blades in the training that each contact blade carries a point of contact. In this case, this contact point is mechanically decoupled from the other contact blades.

Insbesondere bei Kabelbaumsteckern, die Buchsenkontakte in den beschriebenen Ausführungen beinhalten und bei denen möglicherweise auch mehrere Kontaktlamellenpaare nebeneinander angeordnet sind, ist die Funktion im Wesentlichen durch die Breite des Steckkontakts begrenzt, da bei zu geringem Abstand zwischen den Kontaktlamellen sich diese unter Umständen gegenseitig behindern würden und die Breite der Kontaktlamellen selbst angesichts der notwendigen Stromtragquerschnitte und mechanischen Belastungen ein gewisses Mindestmaß nicht unterschreiten sollten.In particular, in wiring harness connectors that include socket contacts in the described embodiments and in which possibly also a plurality of pairs of contact lamellae are arranged side by side, the function is essentially limited by the width of the plug contact, since at too small a distance between the Contact lamellae these would interfere with each other under certain circumstances and the width of the contact blades should not be less than a certain minimum, even in view of the necessary current carrying cross-sections and mechanical loads.

Aus der DE 42 42 972 A1 ist bereits ein elektrischer Steckverbinder bekannt, der dem Herstellen einer sicheren elektrischen Verbindung eines Kontaktstiftes in einem Kontaktierungsbereich einer Kontaktbuchse dient. Bei diesem elektrischen Steckverbinder bildet ein Hülsenkörper, der mit Befestigungsmitteln für Anschlussleitungen befestigt ist, einen Buchsenkontakt für die verschiebliche Aufnahme eines Kontaktstiftes. Dabei ist in dem Hülsenkörper ein pressend an den Stiftkontakt anlegbarer Lamellenkäfig axial fixiert untergebracht, wobei zur sicheren und effektiven Kontaktierung der Lamellenkäfig durch einen zylinderförmig gerollten ebenen Blechzuschnitt gebildet ist, dessen Längsrandstreifen durch eine Anzahl im Abstand nebeneinander sich erstreckender Stege miteinander verbunden sind. In den freien Räumen zwischen den Stegen sind an den Längsrandstreifen als Kontaktpunkte dienende, gegenüberliegend angeschnittene Kontaktlappen vorgesehen, die über einen ersten Abschnitt in Richtung der Mittellängsachse des Lamellenkäfigs eingebogen und am durch die freien Enden gebildeten zweiten Abschnitt zurückgebogen sowie kürzer als die halbe Länge des Lamellenkäfigs ausgebildet sind. Der Lamellenkäfig stellt ein rohrförmiges Einschubtell dar, an dessen Umfang die Kontaktlamellen freigeschnitten und nach innen hin eingebogen sind. Der Lamellenkäfig ist ein herstellungstechnisch aufwändiges Zusatzteil, das sehr exakt auf kleinstem Bauraum im elektrischen Steckverbinder montiert werden muss.From the DE 42 42 972 A1 An electrical connector is already known, which serves to establish a secure electrical connection of a contact pin in a contacting region of a contact socket. In this electrical connector forms a sleeve body, which is fastened with fastening means for connecting lines, a female contact for the slidable receiving a contact pin. In this case, in the sleeve body a collapsible cage pin which can be pressed against the pin contact is accommodated in an axially fixed manner, the laminated cage being formed by a cylindrical rolled flat sheet metal blank for safe and effective contacting, whose longitudinal edge strips are connected to one another by a number of spaced apart webs. In the free spaces between the webs serving as contact points, oppositely trimmed contact tabs are provided on the longitudinal edge strips, which are bent over a first portion in the direction of the central longitudinal axis of the lamellar cage and bent back at the second portion formed by the free ends and shorter than half the length of the lamellar cage are formed. The lamellar cage represents a tubular Einschubtell, on the circumference of the contact blades are cut free and inflected towards the inside. The lamellar cage is a production-technically complex additional part, which must be mounted very precisely in the smallest space in the electrical connector.

Aufgabe der ErfindungObject of the invention

Die Aufgabe der Erfindung besteht darin, einen Buchsenkontakt der vorstehenden Art derart weiterzubilden, dass es möglich ist, die Zahl der unabhängigen, voneinander kontaktierenden Kontaktpunkte und stromleitenden Kontaktlamellen auf einem begrenzten Raum einer Breite eines Steckers signifikant zu erhöhen.The object of the invention is to develop a female contact of the above type such that it is possible to significantly increase the number of independent contacting contact points and current-conducting contact blades in a limited space of a width of a connector.

Lösung der AufgabeSolution of the task

Der Kerngedanke der Lösung der Aufgabe ist es, mindestens zwei Kontaktpunkte in Richtung der Einführung des Steckkontakts in den Buchsenkontakt hintereinander anzuordnen.The core idea of the solution of the problem is to arrange at least two contact points in the direction of insertion of the plug contact in the socket contact one behind the other.

Es wird vorgeschlagen, zwei oder mehr Kontaktlamellen paarweise hintereinander anzuordnen, wobei sich diese teilweise überdecken. Die Ausbildung der Kontaktlamellen ist jedoch derart ausgestaltet, dass die Kontaktpunkte auf unterschiedlichen Kontaktlamellen angeordnet sind, so dass mindestens zwei oder sogar mehr Kontaktlamellen in den Kontaktierungsbereich des Buchsenkontaktes hineinragen. Die Kontaktlamellen selbst erstrecken sich von dem Übergang des Anschlussteils zu dem Kontaktteil in den Kontaktierungsbereich des Buchsenkontakts und stellen somit im Kontaktierungsbereich mehrere Kontaktpunkte bereit. Somit ist eine Redundanz bezüglich der Kontaktierung des einzuführenden Steckkontakts gegeben.It is proposed to arrange two or more contact blades in pairs one behind the other, whereby these partially overlap. However, the design of the contact blades is designed such that the contact points are arranged on different contact blades, so that at least two or even more contact blades protrude into the contacting region of the socket contact. The contact blades themselves extend from the transition of the connection part to the contact part in the contacting region of the socket contact and thus provide several contact points in the contacting region. Thus, there is a redundancy with respect to the contacting of the plug-in contact to be inserted.

Vorteile der ErfindungAdvantages of the invention

Einer der wesentlichen Vorteile der Erfindung besteht darin, dass auf diese Weise die Zahl der Kontaktpunkte und Stromleiter gegenüber den bisherigen Lösungen mindestens verdoppelt werden.One of the significant advantages of the invention is that in this way the number of contact points and conductors compared to the previous solutions are at least doubled.

Insbesondere bei Ausgestaltungen von Buchsenkontakten sind die entsprechenden Kontaktlamellen paarweise gegenüber angeordnet, so dass die entsprechenden Kontaktnormalkräfte auf den eingeführten Steckkontakt beidseitig wirken können.In particular, in embodiments of female contacts the corresponding contact blades are arranged in pairs opposite, so that the corresponding contact normal forces can act on both sides of the inserted plug contact.

Bei einer bevorzugten Ausführungsform wird das freie Ende der ersten bzw. vorderen Kontaktlamelle, die bei der Einführung des Steckkontakts in den Buchsenkontakt kontaktiert wird, derart ausgebildet, dass das freie Ende nach innen in den Kontaktierungsbereich hineingebogen ist. In der so entstanden Kehlung sind die freien Enden des zweiten Kontaktlamellenpaars positioniert. Dadurch wird erreicht, dass diese gegen eine Hintersteckung durch den Steckkontakt geschützt sind.In a preferred embodiment, the free end of the first or front contact blade, which is contacted in the insertion of the plug contact into the socket contact, is formed such that the free end is bent inwardly into the contacting region. The free ends of the second pair of contact lamellae are positioned in the groove thus formed. This ensures that they are protected against back insertion through the plug contact.

Der Raum in der Kehlung des vorderen Kontaktlamellenpaares muss dabei so ausreichend ausgebildet sein, dass das innenliegende zweite Kontaktlamellenpaar bei eingestecktem Kontaktpartner in seinem freien Federweg nicht behindert wird und es unabhängig von dem ersten Kontaktlamellenpaar seine Kontaktnormalkräfte auf den Steckkontakt entfalten kann.The space in the groove of the front contact lamellae pair must be sufficiently formed so that the inner second pair of contact lamellae is not hindered when the contact partner is inserted in its free travel and it is independent from the first contact blade pair can develop its contact normal forces on the plug contact.

Da sich das vordere Kontaktlamellenpaar von dem Übergang des Anschlussteils zu dem Kontaktteil bis zu dem Öffnungsbereich des Buchsenkontakts erstreckt und von dort zurück in den Kontaktierungsbereich geführt ist, entsteht im Öffnungsbereich des Buchsenkontakts durch die so herbeigeführte Biegung eine zusätzliche Einführhilfe für den Steckkontakt. Zudem wird dadurch auch vermieden, dass das vordere Kontaktlamellenpaar durch den Steckkontakt hintersteckt wird.Since the front contact lamellae pair extends from the transition of the connection part to the contact part up to the opening area of the socket contact and is guided from there back into the contact area, an additional insertion aid for the plug contact is created in the opening area of the socket contact by the bending thus brought about. In addition, this also avoids that the front contact lamellae is backed by the plug contact.

Vorzugsweise ist der Buchsenkontakt aus einem einstückigen Stanz- und Biegeteil hergestellt.Preferably, the socket contact is made of a one-piece stamped and bent part.

In einer weiteren vorteilhaften Ausbildung des Buchsenkontaktes sind auch die Kontaktpunkte entsprechend vergoldet, um so eine bessere Stromleitungsfähigkeit zu erzielen. Nach Beendigung des Stanz- und Biegeprozesses zur Herstellung des Buchsenkontakts wird der Buchsenkontakt an den jeweiligen freien Enden des Stanz- und Biegeteils verschweißt, vorzugsweise mit einer Laserverschweißung.In a further advantageous embodiment of the socket contact and the contact points are gold plated accordingly, so as to achieve a better power conductibility. Upon completion of the stamping and bending process to make the socket contact, the socket contact is welded to the respective free ends of the stamped and bent part, preferably with a laser weld.

Bei einem anderen Ausführungsbeispiel sind die Kontaktlamellen zwar hintereinander angeordnet, jedoch nicht auf derselben Ebene. Dies bringt den Vorteil mit sich, dass auch bei dünneren Steckkontakten zumindest eine Kontaktpunkt mit dem in den Buchsenkontakt eingeführten Steckkontakt kontaktiert.In another embodiment, the contact blades are indeed arranged one behind the other, but not on the same plane. This has the advantage that contacted even with thinner plug contacts at least one contact point with the inserted into the socket contact plug contact.

Durch die paarweise Anordnung von nicht voneinander abhängigen Kontaktlamellen ist es möglich, ein definiertes und nahezu redundantes Stecksystem, bestehend aus Buchsenkontakt und Steckkontakt, insbesondere bei Hochstromkontakten zu integrieren, ohne den Gesamtbauraum der Kontakte wesentlich zu verändern.Due to the paired arrangement of non-interdependent contact blades, it is possible to integrate a defined and nearly redundant plug-in system consisting of socket contact and plug contact, especially in high-current contacts, without significantly changing the overall space of the contacts.

Durch die neuartige Anordnung der Kontaktlamellen kann die Stromtragfähigkeit gegenüber den bisher bekannten Kontaktsystemen wesentlich erhöht werden.Due to the novel arrangement of the contact blades, the current carrying capacity over the previously known contact systems can be substantially increased.

Auch die Führung und Ausrichtung des Kontaktpunkts auf dem Steckkontakt kann verstärkt werden, was zu einem positiven Effekt hinsichtlich der Schüttelfestigkeit des Kontaktsystems, bestehend aus Buchsenkontakt und Steckkontakt führt.Also, the guidance and alignment of the contact point on the plug contact can be strengthened, which leads to a positive effect in terms of the chipping resistance of the contact system, consisting of socket contact and plug contact.

Weitere vorteilhafte Ausgestaltungen gehen aus der nachfolgenden Beschreibung, den Zeichnungen sowie den Ansprüchen hervor.Further advantageous embodiments will become apparent from the following description, the drawings and the claims.

Beschreibung eines AusführungsbeispielsDescription of an embodiment

Der in Figur 1 dargestellte Buchsenkontakt 1 zur Herstellung einer elektrischen Steckverbindung besteht im Wesentlichen aus einem Anschlussteil 2 für die Aufnahme eines elektrischen Leiters 3 sowie aus einem Kontaktteil 4. Der Buchsenkontakt 1 weist einen Öffnungsbereich 10 zur Aufnahme eines in Figur 1 nicht dargestellten Steckkontakts auf. Das Kontaktteil 4 dient zur Kontaktierung des Steckkontakts. In einem in dem Buchsenkontakt 1 ausgebildeten Kontaktierungsbereich K erstrecken sich Kontaktlamellen 5, 6, 7, 8 und zwar federschenkelartig von einem Ende 9 des Anschlussteils 2. Das eine Ende 9 bildet den Übergang von dem Anschlussteil 2 zu dem Kontaktteil 4.The in FIG. 1 Socket contact 1 shown for producing an electrical plug connection consists essentially of a connection part 2 for receiving an electrical conductor 3 and a contact part 4. The socket contact 1 has an opening portion 10 for receiving a in FIG. 1 not shown plug contact. The contact part 4 serves for contacting the plug contact. Contact lances 5, 6, 7, 8 extend in a spring-like manner from one end 9 of the connecting part 2 in a contacting region K formed in the socket contact 1. The one end 9 forms the transition from the connecting part 2 to the contact part 4.

Die Kontaktlamellen 5, 6, 7, 8 weisen jeweils ein Ende auf, wobei an den Enden Kontaktpunkte 5k, 6k, 7k und 8k angeordnet sind. Bei den bei diesem Ausführungsbeispiel dargestellten erfindungsgemässen Buchsenkontakt 1 sind die Kontaktlamellen 5, 6, 7, 8 paarweise und sich jeweils gegenüberliegend angeordnet.The contact blades 5, 6, 7, 8 each have an end, wherein at the ends of contact points 5k, 6k, 7k and 8k are arranged. In the inventive socket contact 1 shown in this embodiment, the contact blades 5, 6, 7, 8 arranged in pairs and each opposite.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel erstreckt sich ein erstes Paar von Kontaktlamellen 5, 6 bis in den Öffnungsbereich 10 des Buchsenkontakts 1, wobei das jeweilige freie Ende der Kontaktlamellen 5a, 6a eine in den Kontaktierungsbereich K ausgerichtete Biegung 11 aufweist, so dass die tatsächlichen freien Enden innerhalb des Kontaktierungsbereichs K enden. Somit erstreckt sich das erste Paar der Kontaktlamellen 5, 6 von dem Übergang des Anschlussteils 2 zu dem Kontaktteil 4 bis zum Ende des Buchsenkontakts 1 und von dort zurück in den Kontaktierungsbereich K. Die Kontaktpunkte 5k, 6k auf den Kontaktlamellen 5, 6 sind derart ausgestaltet, dass diese mit einem in den Figuren 1 und 2 nicht näher dargestellten Steckkontakt kontaktieren. Vorzugsweise sind die Kontaktpunkte 5k, 6k derart angeordnet, dass sie einander gegenüberliegen.At the in FIG. 1 illustrated embodiment, a first pair of contact blades 5, 6 extends into the opening portion 10 of the socket contact 1, wherein the respective free end of the contact blades 5a, 6a has a directed into the contact area K bend 11, so that the actual free ends within the contacting region C end. Thus, the first pair of contact blades 5, 6 extends from the junction of the connector 2 to the contact part 4 to the end of the socket contact 1 and from there back into the contacting region K. The contact points 5k, 6k on the contact blades 5, 6 are configured that this one with in the Figures 1 and 2 contact plug contact not shown. Preferably, the contact points 5k, 6k are arranged so as to face each other.

Das weitere Kontaktlamellenpaar 7, 8 erstreckt sich von dem Übergang des Anschlussteils 2 zu dem Kontaktteil 4 in den Kontaktierungsbereich K und weist ebenfalls ein freies Ende 7a, 8a auf, wobei die freien Enden keine nach innen in den Kontaktierungsbereich K ausgerichtete Biegung aufweisen. Die freien Enden 7a, 8a, sind derart ausgerichtet, dass sie innerhalb der durch die Biegung 11 der ersten Kontaktlamellenpaare 5, 6 ausgebildete Kehlung 12 (Figur 2) enden. Dadurch wird gewährleistet, dass die beiden Kontaktlamellenpaare 5, 6, 7, 8 unabhängig voneinander beweglich sind. Das zweite Kontaktlamellenpaar 7, 8 weist ebenfalls Kontaktpunkte 7k, 8k auf, die mit einem nicht näher dargestellten Steckkontakt in Verbindung treten.The further contact lamellae pair 7, 8 extends from the transition of the connection part 2 to the contact part 4 in the contact area K and also has a free end 7a, 8a, wherein the free ends have no inwardly aligned in the contact area K bending. The free ends 7a, 8a are aligned in such a way that they are formed inside the groove 12 (FIG. 2) formed by the bend 11 of the first contact lamellae pairs 5, 6. FIG. 2 ) end up. This will ensure that the two pairs of contact blades 5, 6, 7, 8 are movable independently of each other. The second contact blade pair 7, 8 also has contact points 7k, 8k, which come into contact with a plug contact, not shown.

In den Figuren 3 und 4 ist der erfindungsgemäße Buchsenkontakt 1 in einem gesteckten Zustand mit einem Steckkontakt S dargestellt. Der Steckkontakt S kontaktiert mit seiner Oberfläche 14 unmittelbar die Kontaktpunkte 5k, 6k, 7k, 8k der jeweiligen von dem freien Ende 9 sich erstreckenden Kontaktlamellen 5, 6, 7, 8. Aufgrund der federschenkelartigen Anordnung der Kontaktlamellen 5, 6, 7, 8 kontaktieren die Kontaktpunkte 5k, 6k, 7k, 8k jeweils mit einer Kontaktnormalkraft FK die Oberfläche 14 des Steckkontakts S (Figur 3). Idealerweise wird der Steckkontakt S somit an vier Punkten kontaktiert. Sofern durch Reibkorrosion oder sonstige Gegebenheiten die Kontaktierung aller vier Kontaktpunkte mit dem Steckkontakt S nicht gewährleistet ist, reicht zur Herstellung einer elektrischen Steckverbindung die Kontaktierung einer Kontaktlamelle bzw. eines Kontaktpunkts mit dem Steckkontakt S aus. Durch die Vielzahl der Kontaktpunkte wird die Kontaktierungswahrscheinlichkeit erheblich erhöht.In the FIGS. 3 and 4 the socket contact 1 according to the invention is shown in a plugged state with a plug contact S. The plug contact S contacted with its surface 14 directly the contact points 5k, 6k, 7k, 8k of each of the free end 9 extending contact blades 5, 6, 7, 8. Due to the spring leg-like arrangement of the contact blades 5, 6, 7, 8 contact the contact points 5k, 6k, 7k, 8k each with a contact normal force F K the surface 14 of the plug contact S ( FIG. 3 ). Ideally, the plug contact S is therefore contacted at four points. If contact with all four contact points with the plug contact S is not ensured by fretting corrosion or other conditions, the contacting of a contact blade or a contact point with the plug contact S is sufficient to produce an electrical plug connection. Due to the large number of contact points, the contact probability is considerably increased.

In Figur 5A - D sind die einzelnen Verfahrensschritte dargestellt, wie ein Buchsenkontakt 1 von einem nicht gesteckten Zustand (Darstellung A) in einen gesteckten Zustand (Darstellung D) geführt werden kann.In FIG. 5A-D the individual process steps are shown how a socket contact 1 from a non-inserted state (representation A) in a mated state (representation D) can be performed.

Dabei wird der Steckkontakt S in Pfeilrichtung 15 in den Buchsenkontakt 1 geführt (Darstellung A). Dabei drückt die Spitze 16 (Darstellung B und C) des Steckkontakts S das erste Kontaktlamellenpaar 5, 6 federartig auseinander, wobei die Kontaktpunkte 5k, 6k auf der Oberfläche 14 des Steckkontakts S gleiten. Der Steckkontakt S wird weiter in Pfeilrichtung 15 geführt, bis der Steckkontakt S (Darstellung D) auch das zweite Kontaktlamellenpaar 7, 8 erreicht. Die jeweiligen Kontaktpunkte 7k, 8k des Kontaktlamellenpaars 7, 8 werden ebenfalls federartig auseinandergespreizt, wobei die Kontaktpunkte 7k, 8k auf der Oberfläche 14 des Steckkontakts S gleiten. Der Steckkontakt S wird soweit in den Buchsenkontakt 1 hineingeführt, bis ein in der Zeichnung nicht dargestellter Anschlag erreicht wird. Zur Herbeiführung einer elektrischen Steckverbindung reicht es jedoch aus, sobald ein erstes Kontaktlamellenpaar (unabhängig welches) den Kontakt herstellt.In this case, the plug contact S is guided in the direction of arrow 15 in the socket contact 1 (illustration A). The tip 16 (illustration B and C) of the plug-in contact S presses the first pair of contact lamellae 5, 6 spring-apart, wherein the contact points 5k, 6k slide on the surface 14 of the plug contact S. The plug contact S is further guided in the direction of arrow 15 until the plug contact S (representation D) and the second contact blade pair 7, 8 reached. The respective contact points 7k, 8k of the contact blade pair 7, 8 are also spread apart like a spring, with the contact points 7k, 8k sliding on the surface 14 of the plug contact S. The plug contact S is so far led into the socket contact 1 until a not shown in the drawing stop is reached. To bring about an electrical connector, however, it is sufficient as soon as a first pair of contact blades (regardless of which) makes contact.

In Figur 6A - G ist die Herstellung des erfindungsgemässen Buchsenkontakts 1 in unterschiedlichen Schritten dargestellt.In Figure 6A - G the production of the inventive socket contact 1 is shown in different steps.

Als Ausgang dient ein Blechbiegeteil 17 in der Ausgestaltung, wie es in Darstellung A in zwei Ansichten gezeigt ist. Die Aufteilung in Anschlussteil 2 und in Kontaktteil 4 ist bereits erkennbar. Die Kontaktlamellen 5, 6, 7, 8 sind vorgestanzt und werden durch weitere Biegeprozesse in die gewünschte Form gebracht. Durch unterschiedliche Biegeprozesse, dargestellt in den Darstellungen B bis G, wobei in Darstellung C eine weitere Ansicht gezeigt ist, wird der erfindungsgemässe Buchsenkontakt 1 hergestellt. Sobald der Buchsenkontakt 1 fertiggestellt ist (Darstellung G) werden die jeweiligen Enden mittels eines oder mehrerer Laserschweißpunkte L verbunden, so dass eine kastenförmige Ausbildung entsteht.The output is a sheet metal bending part 17 in the embodiment, as shown in illustration A in two views. The division into connection part 2 and contact part 4 is already recognizable. The contact blades 5, 6, 7, 8 are pre-punched and are brought by further bending processes in the desired shape. By different bending processes, shown in the illustrations B to G, wherein in representation C a further view is shown, the inventive socket contact 1 is produced. As soon as the socket contact 1 has been completed (illustration G), the respective ends are connected by means of one or more laser welding points L, so that a box-shaped formation results.

Aufgrund der Ausgestaltung, dass in einem Buchsenkontakt mehrere Kontaktlamellenpaare, insbesondere deren Kontaktpunkte in Steckrichtung hintereinander angeordnet sind, ist es möglich geworden, ein definiertes und vollständig redundantes Steckverbindungssystem anzubieten, ohne dass der Gesamtbauraum für die Herstellung des Kontakts wesentlich verändert wird.Due to the configuration that a plurality of pairs of contact lamellae, in particular their contact points in the plug-in direction are arranged one behind the other in a socket contact, it has become possible to offer a defined and completely redundant plug-in connection system without the overall installation space for the production of the contact being substantially changed.
