Description

Die Erfindung betrifft ein Kontaktelement für einen Steckverbinder gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a contact element for a connector according to the features of the preamble of claim 1.

Ausgangspunkt als Stand der Technik ist die DE 10 2006 053 152 B3 . Das Kontaktelement aus diesem bekannten Stand der Technik weist zwar auch ein erstes Basisteil auf, jedoch ist dieses Basisteil mit zwei Wellenbergen versehen. Dem ersten Basisteil ist ein zweites Basisteil, ebenfalls mit zwei Wellenbergen, zugeordnet. An diesem zweiten Basisteil ist eine Rastfeder-Materiallage angefügt, mit der das Kontaktelement in einer Kontaktkammer eines Steckverbinders festgelegt wird. Insgesamt bietet das aus diesem Stand der Technik bekannte Kontaktelement zwar einen Aufbau, der hinsichtlich der Montage und der Kontaktsicherheit ausreichend, jedoch verbesserungsfähig ist.Starting point as state of the art is the DE 10 2006 053 152 B3 , Although the contact element of this known prior art also has a first base part, however, this base part is provided with two wave crests. The first base part is associated with a second base part, also with two wave crests. At this second base part a detent spring material layer is added, with which the contact element is fixed in a contact chamber of a connector. Overall, although known from this prior art contact element has a structure that is sufficient in terms of assembly and contact reliability, but can be improved.

Demgegenüber ist es Aufgabe der Erfindung, ein verbessertes Kontaktelement für eine Steckverbindung bereitzustellen.In contrast, it is an object of the invention to provide an improved contact element for a connector.

Grundsätzlich ist ein Steckverbinder derart aufgebaut, dass er ein Gehäuse aufweist, das zumindest eine, meistens mehrere Kontaktkammern aufweist. In diese Kontaktkammern werden Kontaktelemente eingesetzt und in dieser Kontaktkammer einmal, oftmals auch zweifach verrastet. Das Kontaktelement selber ist am Ende einer elektrischen Leitung angeordnet, wobei ein elektrischer Leiter der Leitung mit dem Kontaktelement elektrisch kontaktiert ist, zum Beispiel durch Verlöten, Vercrimpen oder dergleichen.Basically, a connector is constructed such that it has a housing having at least one, usually a plurality of contact chambers. In these contact chambers contact elements are used and locked once in this contact chamber, often twice. The contact element itself is arranged at the end of an electrical line, wherein an electrical conductor of the line is electrically contacted with the contact element, for example by soldering, crimping or the like.

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

Erfindungsgemäß ist vorgesehen, dass in einem Kontaktbereich das Kontaktelement eine federnde Kontaktgeometrie für ein Gegenkontaktelement aufweist, wobei diese Kontaktgeometrie doppelt vorhanden ist. Dadurch wird zum einen der Kräfteaufwand, der erforderlich ist, um das Gegenkontaktelement in den Kontaktbereich einzuführen, verringert, weil beide Kontaktgeometrien federnd ausgebildet sind. Diese federnde Ausbildung der Kontaktgeometrie hat darüber hinaus den Vorteil, dass dauerhaft ausreichende Kontaktkräfte auf das Gegenkontaktelement wirken, sodass ein zuverlässiger elektrischer Kontakt zwischen dem Kontaktbereich des Kontaktelementes und dem Gegenkontaktelement realisiert ist.According to the invention it is provided that in a contact region, the contact element has a resilient contact geometry for a mating contact element, wherein this contact geometry is duplicated. As a result, on the one hand, the expenditure of force required to introduce the mating contact element into the contact region is reduced because both contact geometries are resilient. This resilient design of the contact geometry has the additional advantage that permanently sufficient contact forces act on the mating contact element, so that a reliable electrical contact between the contact region of the contact element and the mating contact element is realized.

In Weiterbildung der Erfindung weist diese Kontaktgeometrie einen wellenförmigen Verlauf auf. In besonders vorteilhafter Weise ist der wellenförmige Verlauf der federnden Kontaktgeometrie symmetrisch (im Schnitt des Kontaktelementes betrachtet) ausgebildet. Dadurch erhöht sich in vorteilhafter Weise die Kontaktsicherheit in einem deutlich größeren Maße, als wenn sich Kontaktpunkte eines wellenförmigen Verlaufes einer Kontaktgeometrie in der Art und Weise gegenüberstehen, dass der eine Wellenberg fest und der andere Wellenberg, der gegenüber liegt, federnd ausgebildet ist.In development of the invention, this contact geometry has a wave-shaped course. In a particularly advantageous manner, the wave-shaped course of the resilient contact geometry is symmetrical (viewed in section of the contact element) is formed. This advantageously increases the contact reliability to a significantly greater extent than if contact points of a wave-shaped course of a contact geometry are facing one another in such a way that the one wave crest is fixed and the other crest which lies opposite is resilient.

In Weiterbildung der Erfindung ist vorgesehen, dass der Kontaktbereich gebildet ist von einem Basisteil, von dem ein erster federnder Kontaktteil ausgeht, sowie einem zweiten feststehenden Basisteil, von dem ein zweiter federnder Kontaktteil ausgeht, wobei die beiden Basisteile über ein senkrecht dazu ausgerichtetes Verbindungsteil miteinander verbunden sind. Diese Ausgestaltung hat einerseits den Vorteil, dass ein solches Kontaktelement in einem üblichen Verfahren, wie zum Beispiel einem Stanz-Biege-Verfahren, schnell, kostengünstig und rationell hergestellt werden kann. Gleichzeitig lässt sich damit eine gegenüber dem Stand der Technik deutlich verbesserte Kontaktgeometrie realisieren, indem zwei feststehende Basisteile ausgebildet werden, an denen jeweils ein federnder Kontaktteil absteht, und die beiden Basisteile über ein senkrecht dazu ausgerichtetes Verbindungsteil miteinander verbunden sind.In a further development of the invention, it is provided that the contact region is formed by a base part, from which a first resilient contact part extends, and a second stationary base part, from which a second resilient contact part extends, wherein the two base parts connected to each other via a perpendicular thereto aligned connecting part are. On the one hand, this embodiment has the advantage that such a contact element can be produced quickly, inexpensively and efficiently in a conventional method, such as, for example, a punch-bending method. At the same time, this makes it possible to realize a contact geometry that is significantly improved over the prior art by forming two fixed base parts, on each of which a resilient contact part protrudes, and the two base parts are connected to one another via a connection part aligned perpendicular thereto.

In Weiterbildung der Erfindung ist an einem Ende des zweiten Basisteiles ein abgewinkelter Bereich vorgesehen. Mit diesem abgewinkelten Bereich wird das Kontaktelement zumindest einmal in der Kontaktkammer des Steckverbinders festgelegt, wenn es dort hineinbewegt, insbesondere hineingeschoben wurde. Dadurch lässt sich die Montage eines solchen verbesserten Steckverbinders auch weiterhin verbessern.In a further development of the invention, an angled region is provided at one end of the second base part. With this angled region, the contact element is fixed at least once in the contact chamber of the connector when it is moved in there, in particular pushed into it. As a result, the assembly of such an improved connector can continue to improve.

Im Folgenden wird die Erfindung anhand eines Ausführungsbeispieles näher erläutert.In the following the invention will be explained in more detail with reference to an embodiment.

Die Figuren 1 und 2 zeigen, soweit im Einzelnen dargestellt, ein Kontaktelement 1 für einen Steckverbinder. Ein solches Kontaktelement 1 wird aus einem elektrisch leitenden Material zum Beispiel in einem Stanz-Biege-Verfahren aus einem flächigen Ausgangsmaterial hergestellt.The FIGS. 1 and 2 show, as far as shown in detail, a contact element 1 for a connector. Such a contact element 1 is made of an electrically conductive material, for example in a stamping-bending process of a sheet-like starting material.

Das Kontaktelement 1 weist einen Crimpbereich 2 auf, mit dem es an einem elektrischen Leiter einer Leitung angeschlagen wird. Der äußere Mantel der Leitung wird zwischen zwei Flügeln 3 hindurchgeführt, die nach der Festlegung des elektrischen Leiters im Crimpbereich 2 umgebogen werden, um auf diese Art und Weise eine Zugentlastung zu schaffen. Anstelle des Crimpbereiches 2 ist es denkbar, den elektrischen Leiter nicht oder nicht nur durch einen mechanischen Crimpvorgang, sondern auch durch andere Methoden, wie zum Beispiel durch Löten, mit dem Kontaktelement elektrisch zu kontaktieren. Die Flügel 3 zwecks Zugentlastung können, müssen aber nicht vorhanden sein.The contact element 1 has a crimping region 2, with which it is struck on an electrical conductor of a line. The outer sheath of the conduit is passed between two wings 3, which are bent after the determination of the electrical conductor in the crimping area 2, in order to provide a strain relief in this way. Instead of the crimping region 2, it is conceivable not to electrically contact the electrical conductor with the contact element or not only by a mechanical crimping process but also by other methods, such as by soldering. The wings 3 for the purpose of strain relief can, but need not be present.

Das Kontaktelement 1 weist einen Kontaktbereich 4 auf, der wie folgt gestaltet ist.The contact element 1 has a contact region 4, which is designed as follows.

Ausgehend von dem Crimpbereich 2 ist ein feststehendes erstes Basisteil 5 vorhanden, welches in seiner axialen Erstreckung dazu querliegende Schlitze aufweisen kann, aber nicht muss. Ausgehend von dem ersten Basisteil 5 (genauer an dem dem Crimpbereich abgewandten Ende) ist ein erstes federndes Kontaktteil 6 vorhanden. Dieses erste federnde Kontaktteil 6 wird zum Beispiel durch einen Umbiegevorgang realisiert. Weiterhin ist ein zweites feststehendes Basisteil 7 vorhanden. An dem zweiten feststehenden Basisteil 7 ist einerseits ein zweites federndes Kontaktteil 8 vorgesehen. Auch das zweite feststehende Basisteil 7 kann in seinem axialen Verlauf zumindest einen oder mehrere quer dazu ausgerichtete Schlitze aufweisen.Starting from the crimping region 2, a fixed first base part 5 is present, which in its axial extent may have transversal slots, but need not. Starting from the first base part 5 (more precisely at the end facing away from the crimping region), a first resilient contact part 6 is present. This first resilient contact part 6 is realized for example by a Umbiegevorgang. Furthermore, a second fixed base part 7 is present. On the second fixed base part 7, on the one hand, a second resilient contact part 8 is provided. Also, the second fixed base part 7 can have in its axial course at least one or more transverse thereto aligned slots.

Sowohl das erste Basisteil 5 als auch das zweite Basisteil 7 sind dadurch zueinander feststehend ausgebildet, auch bezüglich des gesamten Kontaktelementes 1, da sie über ein senkrecht ausgerichtetes Verbindungsteil 9 miteinander verbunden sind.Both the first base part 5 and the second base part 7 are thus fixed to each other, also with respect to the entire contact element 1, since they are connected to each other via a vertically aligned connecting part 9.

Die beiden Kontaktteile 6, 8 sind dadurch federnd ausgebildet, dass sie mit ihrem einen Ende sich ausgehend von dem ersten Basisteil 5 bzw. dem zweiten Basisteil 7 in das Innere des Kontaktbereiches 4 hinein erstrecken. Diese Erstreckung wird dadurch realisiert, dass ein laschenförmiges Gebilde von den Basisteilen 5, 7 in etwa um 180° umgebogen wird, sodass dadurch die Kontaktteile 6, 8 entstehen. Das jeweilige freie Ende der Kontaktteile 6, 8 kann durch die zugehörigen Bereiche der feststehenden Basisteile 5, 7 begrenzt werden.The two contact parts 6, 8 are resiliently formed such that they extend with their one end, starting from the first base part 5 and the second base part 7 in the interior of the contact area 4 inside. This extension is realized in that a lug-shaped structure is bent by the base parts 5, 7 in about 180 °, so that thereby the contact parts 6, 8 arise. The respective free end of the contact parts 6, 8 can be limited by the associated areas of the fixed base parts 5, 7.

Die beiden Kontaktteile 6, 8 sind wellenförmig gestaltet, wobei aufgrund dieser Gestaltung jeweils zwei Wellenberge entstehen, die jeweils eine Kontaktstelle 10 für das Gegenkontaktelement bilden.The two contact parts 6, 8 are designed wave-shaped, due to this design two wave peaks arise, each forming a contact point 10 for the mating contact element.

Das eine Basisteil, nämlich das zweite Basisteil 7, weist in seinem einen Endbereich noch einen abgewinkelten Bereich 11 auf. Durch diesen Bereich 11 wird eine Art Rastnase gebildet, mit der das Kontaktelement 1 in einer nicht dargestellten Kontaktkammer in einem ebenfalls nicht dargestellten Steckverbinder festgelegt wird.The one base part, namely the second base part 7, still has an angled region 11 in its one end region. Through this area 11, a kind of detent is formed, with which the contact element 1 is fixed in a contact chamber, not shown, in a connector, also not shown.

In Figur 1 ist abstehend von dem abgewinkelten Bereich 11 ein Vorsprung vorgesehen, der in eine Öffnung des Verbindungsteiles 9 eingreift. Dadurch wird die Bewegung des abgewinkelten Bereiches 11, der ebenfalls federnd ausgehend von dem zweiten feststehenden Basisteil 7 angeordnet ist, definiert begrenzt.In FIG. 1 is protruding from the angled portion 11, a projection provided which engages in an opening of the connecting part 9. As a result, the movement of the angled region 11, which is also arranged resiliently starting from the second stationary base part 7, defined limited.

Figur 2 zeigt im Schnitt den Kontaktbereich 4 gemäß Figur 1, wobei schematisch als Gegenkontaktelement ein Kontaktstift 12 dargestellt ist. Im endmontierten Zustand einer Steckverbindung ist dieser Kontaktstift 12 innerhalb des gesamten Kontaktbereiches 4 vorhanden und wird elektrisch aufgrund der Kontaktstellen 10 kontaktiert. Ist das Gegenkontaktelement, insbesondere der Kontaktstift 12, im Kontaktbereich 4 zwischen den Kontaktstellen 10 zur Anlage gekommen, wird aufgrund der wellenförmigen Geometrie und der federnden Ausgestaltung der Kontaktteile 6, 8 bewirkt, dass diese mit ihren freien Endbereichen zum einen an einem Anschlag 13 an dem ersten feststehenden Basisteil 5 und zum anderen an einem Anschlag 14 des zweiten feststehenden Basisteiles 7 zur Anlage kommen. Dadurch erhöhen sich zum Einen die Kontaktkräfte, wenn das Gegenkontaktelement, insbesondere der Kontaktstift 12, sich vollständig im Kontaktbereich 4 befindet. Das Gegenkontaktelement befindet sich vorzugsweise dann vollständig in dem Kontaktbereich 4, wenn sein freies Ende den zweiten (bei Betrachtung der Figur 2 den rechten Wellenberg mit den zugehörigen Kontaktstellen 10) überstrichen hat. Das bedeutet, dass beispielsweise der Kontaktstift bei Betrachtung der Figur 2 von links nach rechts in den Kontaktbereich 4 eingeführt wird und zunächst die erste, das heißt bei Betrachtung der Figur 2 die linke Kontaktstelle 10 überstreicht. Wird es weiter in den Kontaktbereich 4 eingeführt, überstreicht es auch die rechte Kontaktstelle 10, wobei zu Beginn des Einführens des Kontaktelementes in den Kontaktbereich 4 die freien Enden der beiden Kontaktteile 6, 8 noch nicht an den Anschlägen 13, 14 zur Anlage kamen. Erst wenn die beiden Kontaktstellen 10 überstrichen worden sind und das Gegenkontaktelement (Kontaktstift 12) seine Endlage erreicht hat, werden die freien Enden der beiden Kontaktteile 6, 8 gegen die Anschläge 13, 14 gedrückt, was bewirkt, dass zunächst während des Einführens des Gegenkontaktelementes in den Kontaktbereich 4 die Kräfte geringer waren als sie weiterhin danach nötig sind, um das Gegenkontaktelement in seine Endposition zu bringen. Dadurch wird das Gegenkontaktelement nicht nur verbessert dauerhaft kontaktiert, sondern auch verbessert mechanisch in dem Kontaktbereich 4 festgelegt. FIG. 2 shows in section the contact area 4 according to FIG. 1 , wherein schematically a contact pin 12 is shown as a mating contact element. In the final assembled state of a connector, this contact pin 12 is present within the entire contact area 4 and is contacted electrically due to the contact points 10. Is the mating contact element, in particular the contact pin 12, come into contact area 4 between the contact points 10 to the plant is due to the wave-shaped geometry and the resilient configuration of the contact parts 6, 8 causes these come with their free end portions on the one hand to a stop 13 on the first fixed base part 5 and the other to a stop 14 of the second fixed base part 7 to the plant. As a result, on the one hand, the contact forces increase when the mating contact element, in particular the contact pin 12, is located completely in the contact region 4. The mating contact element is preferably located completely in the contact region 4, when its free end is the second (when viewing the FIG. 2 the right wave crest with the associated contact points 10) has swept over. This means that, for example, the contact pin when viewing the FIG. 2 is introduced from left to right in the contact area 4 and first the first, that is, when looking at the FIG. 2 the left contact point 10 sweeps over. If it is further introduced into the contact region 4, it also passes over the right contact point 10, wherein at the beginning of the insertion of the contact element into the contact region 4, the free ends of the two contact parts 6, 8 did not yet come to rest against the stops 13, 14. Only when the two contact points 10 have been painted over and the mating contact element (contact pin 12) has reached its end position, the free ends of the two contact parts 6, 8 pressed against the stops 13, 14, which causes first during insertion of the mating contact element in the contact area 4, the forces were lower than they continue to be necessary thereafter to bring the mating contact element in its final position. As a result, the mating contact element is not only permanently contacted in an improved manner, but also improved mechanically in the contact region 4.

Das erfindungsgemäße Kontaktelement zeichnet sich mit anderen Worten zum Einen dadurch aus, dass es einen Crimpbereich aufweist, mit dem es an dem elektrischen Leiter der Leitung angeschlagen wird. Im Kontaktbereich weist das erfindungsgemäße Kontaktelement eine Kontaktgeometrie für ein Gegenkontaktelement auf, wobei diese Kontaktgeometrie doppelt vorhanden ist. Diese Kontaktgeometrie, insbesondere für einen Kontaktstift als Gegenkontaktelement weist einen wellenförmigen Verlauf auf, wobei die Wellenform so gewählt ist, dass zwei Wellenberge in Richtung des Gegenkontaktelementes, insbesondere des Kontaktstiftes, weisen und somit diese Wellenberge an dem Gegenkontaktelement anliegen. Gleichzeitig wird von dem Kontaktbereich ein Rastelement gebildet, mit dem das Kontaktelement in der Kontaktkammer des Steckverbinders rastend angeordnet wird. Die beiden zueinander weisenden Kontaktfahnen des Kontaktelementes, die die Wellenform aufweisen, sind vom Einführbereich des Gegenkontaktelementes in Steckrichtung nach hinten in Richtung des Crimpbereiches weisend angeordnet und in etwa parallel zueinander verlaufend. Oberhalb des einen Endes der Kontaktfahne befindet sich ein abgewinkelter Bereich, der die Rastnase zur Verrastung des Kontaktelementes in der Kontaktkammer des Steckverbinders bildet.In other words, the contact element according to the invention is characterized, on the one hand, by having a crimping region, with which it is struck against the electrical conductor of the line. In the contact region, the contact element according to the invention has a contact geometry for a mating contact element, wherein this contact geometry is duplicated. This contact geometry, in particular for a contact pin as a mating contact element has a wave-shaped course, wherein the waveform is selected so that two peaks in the direction of the mating contact element, in particular the contact pin, and thus these peaks lie against the mating contact element. At the same time, a latching element is formed by the contact region, with which the contact element in the contact chamber of the Connector is arranged latching. The two mutually facing contact lugs of the contact element having the waveform are arranged facing away from the insertion of the mating contact element in the insertion direction in the direction of the crimping region and extending approximately parallel to each other. Above the one end of the contact lug is an angled portion which forms the latching lug for locking the contact element in the contact chamber of the connector.

Das gesamte Kontaktelement besteht aus einem elektrisch leitfähigen Material, zum Beispiel einem entsprechenden Blechmaterial, welches zunächst flächig gestaltet ist und einem Stanz-Biege-Verfahren zugeführt wird, so dass das gesamte Kontaktelement einstückig mit Hilfe des Stanz-Biege-Verfahrens hergestellt werden kann. Alternativ dazu ist es denkbar, insbesondere die Kontaktfahnen und / oder den Rastbereich als separate Elemente auszubilden, die entsprechend nach ihrer Herstellung zu einem einteiligen Kontaktelement zusammengefügt werden.The entire contact element consists of an electrically conductive material, for example, a corresponding sheet material, which is initially designed flat and is fed to a punch-bending process, so that the entire contact element can be made in one piece by means of punching-bending process. Alternatively, it is conceivable, in particular, to form the contact lugs and / or the latching region as separate elements, which are joined together according to their manufacture to form a one-piece contact element.
