Direktsteckelement mit kraftfreier Kontaktierung Stand der Technik  Direct plug-in element with non-contacting contact State of the art
Die vorliegende Erfindung betrifft ein Direktsteckelement mit einem The present invention relates to a direct plug-in element with a
Steckergehäuse und einem Direktkontakt für eine Direktkontaktierung von freiliegenden Kontaktbereichen an einem Gegenstück, beispielsweise einer Leiterplatte, sowie eine elektrische Anordnung mit einem derartigen Plug housing and a direct contact for direct contacting of exposed contact areas on a counterpart, such as a printed circuit board, and an electrical arrangement with such
Direktsteckelement.  Direct plug-in element.
In jüngster Zeit werden vermehrt Direktsteckkontakte verwendet, bei denen ein Direktsteckelement unmittelbar auf ein Gegenstück, wie z. B. eine Leiterplatte oder ein Stanzgitter oder Substrat gesteckt wird. Insbesondere bei derRecently, more direct plug contacts are used in which a direct plug directly on a counterpart such. B. a circuit board or a lead frame or substrate is inserted. Especially at the
Verwendung im Fahrzeugbereich ergeben sich jedoch erhöhte Anforderungen hinsichtlich einer Robustheit und Kontaktsicherheit derartiger However, use in the vehicle sector results in increased requirements in terms of robustness and contact reliability of such
Direktsteckverbindungen. Ein wesentlicher Problemkreis bei Direct connections. An essential problem area with
Direktkontaktierungen liegt darin, dass üblicherweise die Direktsteckelemente von vorne auf die Kontaktbereiche an der Leiterplatte aufgeschoben werden, wobei scharfkantige Leiterplattenkanten bzw. Kontaktbereiche zu Direktkontaktierungen is that usually the Direktsteckelemente are pushed from the front to the contact areas on the circuit board, with sharp-edged PCB edges or contact areas to
Beschädigungen des Direktkontakts während des Steckvorgangs führen. Dies resultiert aus einer auf die Kontaktbereiche der Leiterplatte einwirkenden Anpresskraft, die durch zusätzliche Federelemente des Direktkontakts beim Steckvorgang auf die Leiterplatte aufgebaut werden. Folglich werden Damage to the direct contact during plugging. This results from a force acting on the contact areas of the printed circuit board pressing force, which are built up by additional spring elements of the direct contact during insertion onto the circuit board. Consequently
Oberflächen der Direktkontakte und der Kontaktflächen an der Leiterplatte abgerieben und verschleißen bei mehreren Steckvorgängen deutlich, sodass Schädigungen bzw. Funktionsstörungen der elektrischen Anordnung eintreten können.  Surfaces of the direct contacts and the contact surfaces on the printed circuit board worn down and wear in several mating operations significantly, so damage or malfunction of the electrical system can occur.
Offenbarung der Erfindung Das erfindungsgemäße Direktsteckelement mit den Merkmalen des Anspruchs 1 weist demgegenüber den Vorteil auf, dass beim Aufstecken bzw. Entfernen des Direktsteckelements keine auf den Kontaktbereich wirkende Anpresskraft während der Schiebebewegung des Steckvorgangs auftritt. Hierdurch können Verschleißerscheinungen an Direktkontakten des Direktsteckelements sowie Kontaktbereichen einer Leiterplatte signifikant reduziert werden. Somit kann erfindungsgemäß das Direktsteckelement problemlos mehrfach von der Disclosure of the invention In contrast, the direct plug-in element according to the invention with the features of claim 1 has the advantage that no contact force acting on the contact region occurs during the sliding movement of the plug-in operation when plugging in or removing the direct plug element. As a result, signs of wear on direct contacts of the direct plug-in element and contact areas of a printed circuit board can be significantly reduced. Thus, according to the invention, the Direktsteckelement easily multiple of the
Leiterplatte getrennt und wieder aufgesteckt werden. Hierdurch ergibt sich ein weiterer Vorteil, dass dünnere Schutzschichten, welche üblicherweise aus Gold sind, auf den Kontaktflächen an den Kontaktbereichen bzw. den Direktkontakten verwendet werden können. Hieraus resultieren drastische Kosteneinsparungen. Zudem bewirkt der Direktkontakt selbst die Anpresskraft auf den Kontaktbereich, so dass keine zusätzlichen Federelemente erforderlich sind und sich die Anzahl der erforderlichen Bauteile somit reduziert. Dies wird erfindungsgemäß dadurch erreicht, dass das Direktsteckelement ein Steckergehäuse sowie einen PCB separated and plugged back. This results in a further advantage that thinner protective layers, which are usually made of gold, can be used on the contact surfaces at the contact areas or the direct contacts. This results in drastic cost savings. In addition, the direct contact itself causes the contact pressure on the contact area, so that no additional spring elements are required and thus reduces the number of required components. This is inventively achieved in that the direct plug a connector housing and a
Direktkontakt umfasst, welcher für eine Direktkontaktierung mit einem Direct contact includes, which for a direct contact with a
freiliegenden Kontaktbereich eingerichtet ist. Der Direktkontakt ist einstückig und U-förmig mit einem Kontaktlamellenbereich und einem Anpressfederbereich ausgebildet. Hierbei ist ein Kontaktpunkt am Kontaktlamellenbereich in exposed contact area is set up. The direct contact is integrally formed and U-shaped with a contact blade region and a Anpressfederbereich. Here is a contact point on the contact blade area in
Steckrichtung versetzt zu einem Anpresspunkt am Anpressfederbereich angeordnet. Plug-in direction arranged offset to a contact point on Anpressfederbereich.
Die Unteransprüche zeigen bevorzugte Weiterbildungen der Erfindung. The dependent claims show preferred developments of the invention.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der Kontaktpunkt in Steckrichtung vor dem Anpresspunkt angeordnet. Dadurch wird die Anpresskraft des Direktkontakts auf die Trägerplatte erst mit Erreichen des Anpresspunkts erzeugt, sodass der Kontaktbereich der Leiterplatte den Kontaktlamellenbereich beim Steckvorgang im Wesentlichen normalkraftfrei passieren kann. DasAccording to a preferred embodiment of the invention, the contact point is arranged in the insertion direction in front of the contact point. As a result, the contact force of the direct contact on the carrier plate is only generated when the contact point is reached, so that the contact region of the printed circuit board can pass through the contact lamella region during the insertion process essentially without normal force. The
Versatzmaß zwischen dem Kontaktpunkt und dem Anpresspunkt stellt eine normalkraftfreie Überdeckung zwischen dem Kontaktpunkt und dem Offset between the contact point and the contact point provides a normal force-free coverage between the contact point and the
Kontaktbereich der Leiterplatte sicher. Contact area of the PCB safe.
Besonders bevorzugt ist der Direktkontakt am Steckergehäuse beweglich gelagert. Dadurch kann der Direktkontakt der Leiterplatte beim Steckvorgang durch eine Schwenkbewegung ausweichen, bis der Anpressfederbereich erreicht ist. Somit entsteht im Wesentlichen keine Beanspruchung am Particularly preferably, the direct contact is movably mounted on the connector housing. As a result, the direct contact of the circuit board during the insertion process Dodge by a pivoting movement until the pressure spring area is reached. Thus, essentially no stress arises on the
Kontaktlamellenbereich vor dem Kontaktpunkt des Direktkontakts, sodass der Kontaktpunkt den Kontaktbereich der Leiterplatte kraftfrei erreichen kann. Contact lamella area in front of the contact point of the direct contact, so that the contact point can reach the contact area of the circuit board without force.
Weiterhin bevorzugt sind mehrere Direktkontakte parallel nebeneinander im Steckergehäuse angeordnet. Dadurch wird eine sehr einfache und kompakte Bauform mit minimaler Baulänge des Direktsteckelements realisiert. Vorzugsweise weist das Steckergehäuse zumindest einen Führungsbereich auf, der mit einem Gegenstück, z. B. einer Leiterplatte, in Kontakt bringbar ist, wobei der Führungsbereich in Steckrichtung vor dem Kontaktpunkt angeordnet ist. Hierbei ragt eine Stirnseite des Führungsbereichs senkrecht zur Steckrichtung mindestens gleich weit oder weiter als der Kontaktpunkt des Further preferably, a plurality of direct contacts are arranged parallel to each other in the connector housing. As a result, a very simple and compact design is realized with minimal length of the direct plug-in element. Preferably, the connector housing has at least one guide area which is connected to a counterpart, for. As a circuit board, can be brought into contact, wherein the guide portion is arranged in the insertion direction in front of the contact point. In this case, an end face of the guide area protrudes perpendicular to the direction of insertion at least equidistant or wider than the contact point of the
Kontaktlamellenbereichs vor. Somit kann der Kontaktbereich der Leiterplatte tangential und somit kraftfrei bis zum Kontaktpunkt eingeführt werden. Der Führungsbereich taucht dann in eine dafür vorgesehene Ausnehmung bzw. Öffnung in der Leiterplatte ein und sichert das Direktsteckelement, so dass ein kontinuierlich betriebssicherer Direktkontakt gewährleistet ist. Erst nach dem Eintauchen kommt der Kontaktlamellenbereich mit dem freiliegenden Contact lamella area before. Thus, the contact area of the circuit board can be introduced tangentially and thus force-free up to the contact point. The guide area then dips into a recess or opening in the printed circuit board provided for this purpose and secures the direct plug-in element so that a continuously reliable direct contact is ensured. Only after immersion comes the contact lamella area with the exposed one

Gemäß einer bevorzugten Ausgestaltung der Erfindung sind die According to a preferred embodiment of the invention, the
Führungsbereiche seitlich am Steckergehäuse angeordnet. Dadurch kann insbesondere bei einer Vielzahl von parallel nebeneinander angeordnetenGuide areas arranged laterally on the connector housing. As a result, in particular, a plurality of parallel arranged next to each other
Direktkontakten eine platzsparende Anordnung realisiert werden. Ferner sind unabhängig von der Anzahl der Direktkontakte lediglich zwei Direct contacts a space-saving arrangement can be realized. Furthermore, only two are independent of the number of direct contacts

Nachfolgend wird unter Bezugnahme auf Figur 1 eine elektrische Anordnung 1 mit einem ein Direktsteckelement 2 gemäß einem ersten bevorzugten Hereinafter, with reference to Figure 1, an electrical arrangement 1 with a direct plug 2 according to a first preferred
Ausführungsbeispiel der Erfindung im Detail beschrieben. Wie aus Figur 1 ersichtlich ist, umfasst die elektrische Anordnung 1 ein Embodiment of the invention described in detail. As can be seen from FIG. 1, the electrical arrangement 1 comprises a
Direktsteckelement 2 und ein Gegenstück 4, welches in diesem  Direct plug 2 and a counterpart 4, which in this
Ausführungsbeispiel eine einstückig ausgebildete Leiterplatte ist. Das Embodiment is an integrally formed circuit board. The
Gegenstück 4 weist ferner einen Kontaktbereich 40 auf, der freiliegend an einer ersten Flachseite 41 angeordnet ist. Der Kontaktbereich 40 weist hierbei relativ zu einer Steckrichtung S eine Länge L auf und ist mit einem Abstand A von einerCounterpart 4 also has a contact region 40, which is arranged exposed on a first flat side 41. The contact region 40 in this case has a length L relative to a plug-in direction S and is at a distance A from one
Stirnseite 43 des Gegenstücks 4 angeordnet. Das Direktsteckelement 2 umfasst ein im Wesentlichen einstückig ausgebildetes Steckergehäuse 6 mit einer dem aufzunehmenden Gegenstück 4 zugewandten Öffnung 61 und einen Direktkontakt 3. Der Direktkontakt 3 ist im Steckergehäuse 6 starr befestigt und an eine Leitung 5, z. B. mittels Crimpen, angebunden, die aus dem Steckergehäuse 6 herausgeführt ist. End face 43 of the counterpart 4 is arranged. The direct plug-in element 2 comprises a substantially integrally formed plug housing 6 with an opening 61 facing the male counterpart 4 and a direct contact 3. The direct contact 3 is rigidly secured in the plug housing 6 and connected to a line 5, z. B. by crimping, connected, which is led out of the connector housing 6.
Wie aus Figur 1 weiter ersichtlich ist, ist der Direktkontakt 3 einstückig und U- förmig ausgebildet und weist einen Kontaktlamellenbereich 31 , der senkrecht zur Steckrichtung S der ersten Flachseite 41 des Gegenstücks 4 zugewandt ist, und einen gegenüberliegend angeordneten Anpressfederbereich 32 auf, der einer zweiten Flachseite 42 des Gegenstücks 4 zugewandt ist. As can also be seen from FIG. 1, the direct contact 3 is formed in one piece and U-shaped and has a contact lamella region 31 which faces the first flat side 41 of the counterpart 4 perpendicular to the plug-in direction S, and an oppositely arranged pressure spring region 32 which is a second Flat side 42 of the counterpart 4 faces.
Der Kontaktlamellenbereich 31 ist bogenförmig ausgebildet und ragt senkrecht zur Steckrichtung S in die Öffnung 61 des Steckergehäuses 6 derart vor, dass ein Scheitelpunkt einen Kontaktpunkt 33 für einen Kontakt mit dem The contact blade region 31 is arc-shaped and protrudes perpendicular to the insertion direction S in the opening 61 of the plug housing 6 in such a way that a vertex a contact point 33 for contact with the
Kontaktbereich 40 definiert. Der Scheitelpunkt des ebenfalls bogenförmig ausgebildeten Anpressfederbereichs 32 definiert einen Anpresspunkt 34, der in Steckrichtung S mit einem Maß X versetzt zum Kontaktpunkt 33 und in einem Abstand Y von einer hinteren Stirnwand 62 der Öffnung 61 angeordnet ist. Contact area 40 defined. The vertex of the also arcuate formed Anpressfederbereichs 32 defines a contact point 34 which is offset in the insertion direction S with a measure X to the contact point 33 and at a distance Y from a rear end wall 62 of the opening 61.
Beim Einstecken des Gegenstücks 4 kontaktiert der Kontaktbereich 40 aufgrund dieser Anordnung zuerst den Kontaktpunkt 33 am Kontaktlamellenbereich 31 in tangentialer Richtung. Hierbei wirkt keine Kontaktkraft senkrecht zur When inserting the counterpart 4, the contact region 40 first contacts the contact point 33 on the contact lamella region 31 in the tangential direction due to this arrangement. Here, no contact force acts perpendicular to
Steckrichtung S, da eine Höhe H der Öffnung größer als eine Dicke D desPlug-in direction S, since a height H of the opening is greater than a thickness D of the
Gegenstücks 4 bemessen ist. Erst wenn die Stirnseite 43 des Gegenstücks 4 den Anpressfederbereich 32 erreicht, wird senkrecht zur Steckrichtung S am Anpresspunkt 34 sowie am Kontaktpunkt 33 jeweils eine durch Pfeile F1 und F2 gekennzeichnete Federkraft aufgebaut. Hierbei sind das Maß X und der Abstand Y des Direktkontakts 3 vorzugsweise so bemessen, dass deren Summe demCounterpart 4 is measured. Only when the end face 43 of the counterpart 4 reaches the Anpressfederbereich 32, is perpendicular to the insertion direction S at the contact point 34 and at the contact point 33 each one constructed by arrows F1 and F2 spring force. Here, the dimension X and the distance Y of the direct contact 3 are preferably dimensioned so that the sum of the
Abstand A sowie der halben Länge L des Kontaktbereichs 40 am Gegenstück 4 entspricht (X+Y=A+L/2). Dadurch liegt im gestecktem Zustand der Distance A and half the length L of the contact area 40 on the counterpart 4 corresponds to (X + Y = A + L / 2). This is in the inserted state of
Kontaktlamellenbereich 31 ungefähr in der Mitte des freiliegenden Contact lamella area 31 approximately in the middle of the exposed one
Kontaktbereichs 40. Bei der beschriebenen erfindungsgemäßen Anordnung ist es somit möglich, eine im Wesentlichen normalkraftfreie Kontaktierung des Direktkontakts 2 mit dem Kontaktbereich 40 herzustellen, die Beschädigungen am Kontaktlamellenbereich 31 aufgrund scharfer Kanten am Gegenstück 4 bzw. am Kontaktbereich 40 beim Steckvorgang verhindert. Zudem sind keine zusätzlichen Federelemente erforderlich, da die Kontaktkraft durch den Direktkontakt 3 selbst erzeugt wird. Contact area 40. In the described arrangement according to the invention, it is thus possible to produce a substantially normal force-free contacting of the direct contact 2 with the contact region 40, which prevents damage to the contact blade region 31 due to sharp edges on the counterpart 4 and the contact region 40 during insertion. In addition, no additional spring elements are required because the contact force is generated by the direct contact 3 itself.

Kontaktbereich 40 beim Einsteckvorgang in die Öffnung 61 des Steckergehäuses 6 den Kontaktlamellenbereich 31 kontaktiert. Durch diese Schwenkbewegung weicht der Direktkontakt 3 dem Gegenstück 4 aus, sodass keine Normalkraft zwischen dem Kontaktpunkt 33 und dem Kontaktbereich 40 wirksam ist, bis die Stirnseite 43 des Gegenstücks 4 den Anpressfederbereich 32 erreicht hat. Contact area 40 during insertion in the opening 61 of the connector housing 6 contacted the contact blade region 31. By this pivoting movement of the direct contact 3 deviates from the counterpart 4, so that no normal force between the contact point 33 and the contact portion 40 is effective until the end face 43 of the counterpart 4 has reached the Anpressfederbereich 32.
Wie in Figur 2C dargestellt, wird beim vollständigen Aufstecken bzw. Einstecken des Gegenstücks 4 der Anpressfederbereich 32 entgegengesetzt zur Kraft F2 senkrecht zur Steckrichtung S gegen das Steckergehäuse 6 gedrückt. Daraus resultiert eine Schwenkbewegung des Direktkontakts 3 in Richtung eines Pfeils P2 und die gleiche in Pfeilrichtung entgegengesetzte Kraft F1 wird am As shown in FIG. 2C, when the counterpart 4 is plugged in or pushed in completely, the pressing spring area 32 is pressed against the plug housing 6 in a direction opposite to the force F2 perpendicular to the plugging direction S. This results in a pivoting movement of the direct contact 3 in the direction of an arrow P2 and the same in the arrow direction opposite force F1 is on
Kontaktpunkt 33 des Kontaktlamellenbereichs 31 zur Direktkontaktierung mit dem Kontaktbereich 40 erzeugt. Bei der beschriebenen Ausführungsform ist es somit möglich, Beschädigungen des Kontaktlamellenbereichs 31 durch die Schwenk- bzw. Ausweichbewegung des Direktkontakts 3 noch wirksamer zu verhindern. Zudem können dadurch geringe Winkelabweichungen bezüglich der Steckrichtung S beim Einstecken des Gegenstücks 4 ausgeglichen werden. Contact point 33 of the contact blade region 31 for direct contacting with the contact region 40 generated. In the described embodiment, it is thus possible to more effectively prevent damage to the contact blade region 31 by the pivoting or evasive movement of the direct contact 3. In addition, small angular deviations with respect to the insertion direction S during insertion of the counterpart 4 can be compensated.
