Description
Die Erfindung betrifft einen Steckverbinder, insbesondere Direktsteckverbinder zur Kontaktierung von Kontaktöffnungen einer Leiterplatte, mit einem Kontaktträger, welcher über Kodiermittel, insbesondere Kodierstifte und eine Verpolungssicherung, insbesondere in Form von Polungsvorsprüngen, verfügen kann, mit vom Kontaktträger ausgebildeten Leitereinschubkanälen zur Aufnahme von Anschlussleitern sowie mit Kontaktausnehmungen zur Aufnahme von Steckkontakten und mit einer den Kontaktträger an der Leiterplatte haltenden Primärsicherung, insbesondere in Form von Rastelementen.The invention relates to a connector, in particular direct connector for contacting contact openings of a printed circuit board, with a contact carrier, which may have coding, in particular coding pins and a reverse polarity, in particular in the form of Polungsvorsprüngen with formed by the contact carrier conductor insertion channels for receiving connecting conductors and contact recesses for receiving plug contacts and with a contact carrier on the circuit board holding primary fuse, in particular in the form of locking elements.
Solche Steckverbinder, insbesondere zur Kontaktierung eines Anschlussleiters an einer Leiterplatte mittels Steckkontakt, sind aus dem druckschriftlich nicht belegbaren Stand der Technik hinlänglich bekannt. Als Direktsteckverbinder bezeichnet man Steckvorrichtungen, deren Kontakte Leiterabschnitte von Leiterplatten unmittelbar kontaktieren. Die Direktsteckverbinder sind mit Steckkontakten für speziell geformte Leiterplatten versehen. Die Leiterplatten weisen hierfür Durchbrüche auf, deren Innenumfangsflächen mit einer elektrisch leitenden Schicht versehen sind. Die Kontaktfinger der Steckkontakte treten direkt mit dieser leitenden Schicht der Leiterplatte in Kontakt.Such connectors, in particular for contacting a connecting conductor to a printed circuit board by means of a plug contact, are well known from the documentally unassignable prior art. As a direct connector is called plug-in devices whose contacts directly contact conductor sections of printed circuit boards. The direct connectors are provided with plug contacts for specially shaped printed circuit boards. For this purpose, the printed circuit boards have openings whose inner peripheral surfaces are provided with an electrically conductive layer. The contact fingers of the plug contacts come directly into contact with this conductive layer of the printed circuit board.
Es sind gattungsgemäße Steckverbinder bekannt, welche eine Primärsicherung aufweisen, um den Kontaktträger fest an der Leiterplatte anzuordnen und vor einem unbeabsichtigten Lösen des Kontaktträgers von der Leiterplatte, beispielsweise durch Zugkräfte, die von den Anschlussleitern aufgebracht werden, zu schützen. Auch hält die Primärsicherung den Steckverbinder bei Vibrationen fest an der Leiterplatte. So wird eine sichere und dauerhafte Kontaktierung gewährleistet.There are generic connectors are known which have a primary fuse to the contact carrier fixed to the circuit board and to protect against inadvertent release of the contact carrier of the circuit board, for example by tensile forces, which are applied by the connecting conductors. The primary fuse also holds the connector firmly against the PCB during vibration. This ensures a secure and permanent contact.
Diese Primärsicherung umfasst Rastelemente. Diese Rastelemente sind am Kontaktträger angeordnet und kooperieren mit Freischnitten in der Leiterplatte, um den Kontaktträger an der Leiterplatte fest anzuordnen. Hierzu untergreifen Rastmittel, welche von den Rastelementen ausgebildet werden, die Leiterplatte auf der dem Steckverbinder abgewandten Unterseite.This primary fuse comprises locking elements. These locking elements are arranged on the contact carrier and cooperate with cutouts in the circuit board to arrange the contact carrier to the circuit board firmly. For this purpose engage under latching means, which are formed by the locking elements, the circuit board on the side facing away from the connector underside.
Steckverbinder sind einer stetigen Miniaturisierung ausgesetzt. Die Anforderungen an die Sicherung des Steckverbinders an der Leiterplatte bleiben dabei wenigstens konstant.Connectors are subject to constant miniaturization. The requirements for securing the connector to the circuit board remain at least constant.
Aufgabe der Erfindung ist es, einen Steckverbinder zu schaffen, dessen Ausgestaltung eine sichere Anordnung an der Leiterplatte ermöglicht.The object of the invention is to provide a connector whose configuration enables a secure arrangement on the circuit board.
Gelöst wird die Erfindung von einem Steckverbinder mit den Merkmalen des Anspruchs 1, insbesondere mit dessen kennzeichnenden Merkmalen, wonach der Kontaktträger mit einer Sekundärsicherung versehen ist, welche den Kontaktträger zusätzlich zur Primärsicherung an der Leiterplatte festlegt und unabhängig von der Primärsicherung handhabbar ist.The invention is achieved by a connector with the features of
Der wesentliche Vorteil der Erfindung liegt darin, dass der Steckverbinder eine Sekundärsicherung aufweist. Diese legt den Kontaktträger zusätzlich zur Primärsicherung an der Leiterplatte fest, wobei keine Wirkabhängigkeit zwischen Primär- und Sekundärsicherung besteht. Dadurch ist es möglich, bei einem Versagen oder Verlust einer Primärsicherung den Kontaktträger weiterhin sicher an der Leiterplatte festzulegen.The essential advantage of the invention is that the connector has a secondary fuse. This sets the contact carrier in addition to the primary fuse to the circuit board, with no effect dependence between primary and secondary fuse. This makes it possible, in case of failure or loss of a primary fuse continue to set the contact carrier safely on the circuit board.
Vor allem gewährleistet die Sekundärsicherung, dass der Steckverbinder höheren Zugkräften standhält, als es alleine mit der Primärsicherung möglich wäre. Die Haltekräfte von Primär- und Sekundärsicherung addieren sich zumindest teilweise.Above all, the secondary fuse ensures that the connector withstands higher tensile forces than would be possible with the primary fuse alone. The holding forces of primary and secondary fuse add up at least partially.
Ebenso vorteilhaft ist die Möglichkeit, die Sekundärsicherung nur in solchen Fällen vorzusehen, in denen zusätzliche Haltekräfte zur Sicherung des Steckverbinders an der Leiterplatte erforderlich sind.Equally advantageous is the possibility to provide the secondary fuse only in those cases where additional holding forces to secure the connector to the circuit board are required.
Es ist zunächst vorgesehen, dass die Sekundärsicherung ein separat am Kontaktträger montierbarer Raststift ist.It is initially provided that the secondary fuse is a separately mountable on the contact carrier detent pin.
Besonders bevorzugt ist, dass der Raststift in einer Montagestellung am Kontaktträger vorverrastet und in einer Funktionsstellung, in welcher dieser den Kontaktträger an der Leiterplatte festlegt, an der Leiterplatte endverrastet ist.It is particularly preferred that the detent pin pre-locked in a mounting position on the contact carrier and in a functional position, in which this determines the contact carrier on the circuit board is endverrastet on the circuit board.
Aufgrund der Vorverrastung des Raststiftes in dem Kontaktträger wird ein möglicher Verlust oder eine Beschädigung des Raststiftes, beispielsweise beim Transport des Steckverbinders, vermieden.Due to the Vorverrastung the locking pin in the contact carrier a possible loss or damage to the locking pin, for example, during transport of the connector, avoided.
Konkret ist vorgesehen, dass der Raststift mit einer ersten Rastgeometrie versehen ist, welche der Vormontage dient und über eine zweite Rastgeometrie verfügt, welche mit der Leiterplatte zur Festlegung des Kontaktträgers kooperiert.Specifically, it is provided that the detent pin is provided with a first detent geometry, which is used for pre-assembly and has a second detent geometry, which cooperates with the circuit board for fixing the contact carrier.
Weiterhin ist vorgesehen, dass der Raststift in eine Riegelstellung und eine Entriegelstellung bewegbar ist, wobei der Raststift in der Riegelstellung den Kontaktträger an der Leiterplatte festlegt und in Entriegelstellung die festlegende Wirkung des Raststiftes aufgehoben ist.Furthermore, it is provided that the locking pin is movable in a locking position and an unlocking position, wherein the locking pin in the locked position defines the contact carrier on the circuit board and in unlocking the fixing effect of the locking pin is repealed.
Schließlich ist vorgesehen, dass der Raststift in einer den Kontaktträger durchsetzenden, steckrichtungsparallelen Bohrung drehbar angeordnet ist.Finally, it is provided that the locking pin is rotatably disposed in a contact carrier passing through, plug-in direction parallel bore.
Zudem ist vorgesehen, dass die zweite Rastgeometrie den Außenumfang des Raststiftes lediglich teilumfänglich umgibt und dass die zweite Rastgeometrie zwei diametral gegenüberliegende Rastvorsprünge aufweist. Ist der Raststift drehbar im Kontaktträger gelagert, ermöglicht es diese Rastgeometrie im Zusammenspiel mit geeigneten Durchbrüchen der Leiterplatte, die Vorverrastung zu lösen.In addition, it is provided that the second detent geometry surrounds the outer circumference of the detent pin only part of the circumference and that the second detent geometry has two diametrically opposite latching projections. If the detent pin is rotatably mounted in the contact carrier, this detent geometry in conjunction with suitable breakthroughs of the printed circuit board makes it possible to release the pre-locking.
Denkbar ist außerdem, dass die Rastvorsprünge gewindeabschnittartig ausgebildet sind. Die Gewindeabschnitte ermöglichen bei einem drehbar gelagerten Raststift ein Verspannen von Kontaktträger und Leiterplatte.It is also conceivable that the locking projections are formed thread-like section. The threaded sections allow for a rotatably mounted detent pin a bracing of the contact carrier and circuit board.
In einer besonders bevorzugten Ausführungsform ermöglicht der Raststift eine Haltekraft von bis zu 72 Newton.In a particularly preferred embodiment, the locking pin allows a holding force of up to 72 Newton.
Der Raststift kann einen Werkzeugansatz, beispielsweise eine Nut aufweisen. So kann der Raststift mit einem Werkzeug, beispielsweise einem Schraubendreher, in der Bohrung gedreht werden kann. Dazu ist vorgesehen, dass eine Drehung um 90° den Raststift von seiner Riegelstellung in seine Entriegelstellung bewegt.The locking pin may have a tool attachment, for example a groove. Thus, the locking pin with a tool, such as a screwdriver, can be rotated in the hole. For this purpose, it is provided that a rotation of 90 ° moves the locking pin from its locking position to its unlocking position.

Der Steckverbinder 10 weist den Kontaktträger 11 auf, welcher ein Gehäuse 13 für Steckkontakte 12 bildet. Das Gehäuse 13 des Kontaktträgers 11 ist mit Leitereinschubkanälen 14 versehen, die der Aufnahme von hier nicht dargestellten Anschlussleitern dienen. Diese werden über Schneidklemmgabeln 48 mit den Steckkontakten 12 elektrisch verbunden. Die Steckkontakte 12 bilden die Kontaktfinger 49, welche die Kontaktöffnung 36 einer Leiterplatte 19 untergreifen, sobald der Steckverbinder 10 an der Leiterplatte 19 angeordnet ist, wie beispielsweise in
Zudem ist das Gehäuse 13 mit Kontaktausnehmungen 15 ausgestattet, in welche die Steckkontakte 12 eingeschoben werden. Das Gehäuse 13 trägt an seiner Außenfläche mehrere Kodierstifte 16, welche dem Steckverbinder 10 in Steckrichtung vorspringen und den Steckverbinder 10 an der Leiterplatte 19 mit korrespondierender Kodierung, insbesondere in Form von Kodierbohrungen 37, zuordnen.In addition, the
Das Gehäuse 13 weist an seiner Frontseite 20 Rasthaken 21 auf, mittels derer mehrere Steckverbinder 10 zu Konfektionierungszwecken aneinander angeordnet werden können. Auf der Rückseite 22 des Kontaktträgers 11 bildet das Gehäuse 13 Konturen zur Aufnahme 23 von Rasthaken 21 aus, mittels derer weitere Steckverbinder 10 an dem Kontaktträger 11 anordenbar sind.The
Weiterhin ist der Kontaktträger 11 mit einer Verpolungssicherung 18 ausgestattet. Die Verpolungssicherung 18 soll eine kurzschlussgefährdende Kontaktierung der Steckkontakte 12 mit den Kontaktöffnungen 36 der Leiterplatte 19 vermeiden. Die Verpolungssicherung 18 wird von drei der Unterseite des Kontaktträgers 11 entspringenden Polungsvorsprüngen 56 gebildet, wie beispielsweise in
Das Gehäuse 13 des Kontaktträgers 11 ist steckrichtungsparallel mit einer Bohrung 24 durchsetzt. Diese Bohrung 24 weist eine erste Kerbe 25A und eine zweite Kerbe 25B auf. Die zweite Kerbe 25B ist ein optionales und kein zwingendes Merkmal der Bohrung 24.The

Benachbart des Durchbruchs 39 weist die Leiterplatte 19 ein erstes und ein zweites Langloch 35A, 35B auf. Diese Langlöcher 35A und 35B weisen Abschnitte auf, welche zum einen mit einer Primärsicherung 17 und zum anderen mit den Polungsvorsprünge 56 der Verpolungssicherung 18 kooperieren. Das Langloch 35A kooperiert zum einen mit der Primärsicherung 17 und mit einem Polungsvorsprung 56. Das Langloch 35B kooperiert mit der Primärsicherung 17 und mit zwei Polungsvorsprüngen 56 und ist dementsprechend länger ausgebildet als das Langloch 35A. Eine Fehlpositionierung des Steckverbinders 10 an der Leiterplatte 19 ist somit ausgeschlossen.Adjacent to the

Die Rastfläche 55 dient dem Toleranzausgleich zwischen dem Kontaktträger 11 und der Leiterplatte 19. Die an der Leiterplatte 19 angeordneten Rastarme 44 sind beispielsweise in den
In einer besonders bevorzugten Ausführung schließt die abfallende Rastfläche 55 mit der Unterseite 46 der Leiterplatte 19 einen Winkel von 20° ein und ermöglicht so ein Toleranzausgleich von bis zu 10% der Nennstärke der Leiterplatte 19. Auch die abfallende Rastfläche 55 trägt zur Verankerung des Steckverbinders 10 an der Leiterplatte 19 bei. Die durch sie kompensierbare Zugbelastung ist aufgrund der abfallend gerichteten Rastfläche 55 jedoch gering.In a particularly preferred embodiment, the sloping locking
Die Rastarme 44, 45 eilen dem Kontaktträger 11 vor und sind zueinander parallel angeordnet. Der Steckverbinder 10 verfügt über zwei Rastarmpaaren, die an gegenüberliegenden Seiten des Steckverbinders 10 angeordnet sind. Die Rastorgane 50 und 51 gleicher Rastgeometrie liegen einander diagonal am Kontaktträger 11 gegenüber. Am Beispiel der
Durch die diagonal gegenüberliegenden Rastorgane 50 und 51 gleicher Ausgestaltung mit ihren Rastflächen 54 und 55 wird das Verkippen des Steckverbinders 19 unter Zugbelastung verhindert und somit die Kontaktstellenbelastung zwischen den Steckkontakten 12 und den Kontaktlöchern 36 vergleichmäßigt.By the diagonally opposite locking

Die Sicherungshaube 60 umgibt den Kontaktträger 11 außenumfänglich, wobei der Kontaktträger 11 in der Sicherungshaube 60 beweglich angeordnet ist. Der Kontaktträger 11 weist steckrichtungsparallel Riegelzapfen 61 auf, welche dem Kontaktträger 11 voreilen und diesen in der Sicherungshaube 60 in Vormontagestellung positionieren.The securing
Zudem bildet der Kontaktträger 11 Rastprofile 63 und Rastnuten 66 aus, welche dem Kontaktträger 11 in Steckrichtung voreilen und entsprechend der Vor- oder Montagestellung des Kontaktträgers 11 in der Sicherungshaube 60 mit Raststegen 65 der Sicherungshaube 60 kooperieren.In addition, the
Weiterhin weist der Kontaktträger 11 Rastlaschen 62 auf, welche dem Gehäuse 13 an den jeweils kurzen Seiten des Kontaktträgers 11 entspringen. Die Rastlaschen 62 sind rückstellelastisch ausgebildet und kooperieren mit Rastöffnungen 64, welche von der Sicherungshaube 60 ausgebildet werden, wie es in
Zudem bildet die Rastlasche 62 eine Rastnase 67 aus, die mit einer korrespondierenden Rastausnehmung 68, welche von der Sicherungshaube 60 ausgebildet wird, kooperiert. Sobald der Kontaktträger 11 in Montagestellung bewegt wird, wirkt die Rastnase 67 mit der Rastausnehmung 68 zusammen, wie in der Schnittdarstellung in
Im Gegensatz zu der ersten Ausführungform des Steckverbinders 10, entspringen die Primärsicherung 17, die Verpolungssicherung 18 und die Kodierstifte 16 der Sicherungshaube 60 nicht dem Kontaktträger 11. Die Primärsicherung 17 weist in dieser zweiten Ausführungsform des Steckverbinders 10 beidseitig identische Rastarmpaare 44 auf, welche mit den Rastorganen 51 ausgebildet sind. Die Rastorgane weisen die Rastfläche 55 auf, welche dem Toleranzausgleich zwischen Kontaktträger 11 und der Leiterplatte 19 dienen.In contrast to the first embodiment of the
Es ist allerdings auch denkbar, dass die Primärsicherung 17 identisch der ersten Ausführungsform des Steckverbinders 10 ausgestaltet ist, wie beispielsweise in
Auch die Verpolungssicherung 18 kann entsprechend der ersten Ausführungsform des Steckverbinders 10 ausgestaltet sein, wie es exemplarisch der
Zur Konfektionierung des Steckverbinders 10 an der Leiterplatte 19 müssen die Kontaktfinger 49 der Steckkontakte 12 in die Kontaktöffnungen 36 der Leiterplatte 19 aufgenommen werden, um eine elektrische Kontaktierung herzustellen.For assembly of the
Der Kontaktträger 11 wird mittels Riegelzapfen 61 in der Sicherungshaube 60 positioniert, wobei die Rastnuten 66 des Kontaktträgers 11 in Vormontagestellung mit den Raststegen 65 des Sicherungshaube 60 kooperieren. Die Steckkontakte 12 sind in den Kontaktausnehmungen 15 des Kontaktträgers 11 eingeschoben. Da der Kontaktträger 11 und dementsprechend auch die Steckkontakte 12 in der Vormontagestellung beabstandet von der Leiterplatte 19 vorliegen, ist eine elektrische Kontaktierung des Steckverbinders 10 mit der Leiterplatte 19 in der Vormontagestellung des Steckverbinders 10 ausgeschlossen.The
Um den Steckverbinder 10 fertig zu konfektionieren, wird der Kontaktträger 11 in Steckrichtung bewegt und somit in Montagestellung verlagert. Die Raststege 66 greifen nun in die Rastprofile 63 des Kontaktträgers 11 ein und ordnen so den Kontaktträger 11 in der Sichererungshaube 60 an. Zusätzlich rasten die Rastlaschen 62 an den Rastöffnungen 64 der Sicherungshaube 60 fest. Mit der Verlagerung des Kontaktträgerträgers 11 in Steckrichtung werden neben den Kodierstiften 16, welche die Kodierbohrungen 37 der Leiterplatte 19 durchdringen, auch die Steckkontakte 12 in Steckrichtung verlagert. Dadurch kooperieren die Kontaktfinger 49 der Steckkontakte 12 mit den Kontaktöffnungen 36 in der Leiterplatte 19 und ermöglichen so die elektrische Kontaktierung.In order to finish the

Die Rastarme 44 können mittels Druck auf die Lösenocken 53 in den Bewegungsraum rückverlagert werden und so die Sicherungshaube 60 leicht von der Leiterplatte 19 gelöst werden.The
