Description

Die Erfindung betrifft ein Anschlusselement zum Aufbringen auf eine Leiterplatte, aufweisend:

  • eine Anzahl von sich jeweils entlang einer Längsrichtung erstreckenden Anschlussstiften, und
  • ein Gehäuse, in welchem die Anschlussstifte enthalten sind. Gattungsgemäße Anschlusselemente werden beispielsweise verwendet, um elektrische Anschlüsse zu einer Leiterplatte herzustellen. Hierzu wird das Anschlusselement typischerweise auf die Leiterplatte aufgebracht und elektrisch kontaktiert. Das Anschlusselement kann dann dazu dienen, ein Kabel mittels eines Steckers anzuschließen, wodurch ein elektrischer Kontakt zwischen der Leiterplatte und weiteren Komponenten wie beispielsweise einer Stromversorgung, anderen Leiterplatten oder Sensoren hergestellt werden kann.
Häufig sind gattungsgemäße Anschlusselemente als Surface-Mounted Device (SMD) - Anschlusselemente ausgeführt. In der Druckschrift EP 1 873 866 A2 sind solchen Anschlusselement offenbart. Um bei solchen Anschlusselementen einen zuverlässigen elektrischen Kontakt herzustellen, wird typischerweise die Leiterplatte zusammen mit dem aufgelegten Anschlusselement in einem Ofen erwärmt. Dabei werden durch Schmelzvorgänge materialschlüssig elektrische Kontakte hergestellt. Es hat sich jedoch gezeigt, dass bei den hierbei erforderlichen Temperaturen auch Materialien, welche für das Gehäuse oder die Leiterplatte verwendet werden, insbesondere Kunststoffe, ihre bei Raumtemperatur vorhandene Steifigkeit verlieren. Dies kann beispielsweise dazu führen, dass die Leiterplatte unterhalb des Kontaktelements verbogen wird. Auch das Kontaktelement kann sich verbiegen, und zwar insbesondere in dem typischen Fall, in welchem sein Gehäuse aus Kunststoff besteht.The invention relates to a connection element for application to a printed circuit board, comprising:
  • a number of each extending along a longitudinal direction of pins, and
  • a housing in which the pins are included. Generic connection elements are used, for example, to produce electrical connections to a printed circuit board. For this purpose, the connection element is typically applied to the circuit board and electrically contacted. The connection element can then serve to connect a cable by means of a plug, whereby an electrical contact between the circuit board and other components such as a power supply, other circuit boards or sensors can be made.
Frequently, generic connection elements are designed as surface-mounted device (SMD) - connection elements. In the publication EP 1 873 866 A2 are disclosed such connection element. In order to produce a reliable electrical contact with such connection elements, the printed circuit board is typically heated together with the applied connection element in an oven. In this case, electrical contacts are produced by fusion processes materially. However, it has been found that at the temperatures required in this case also materials which are used for the housing or the printed circuit board, in particular plastics, lose their existing at room temperature stiffness. This can, for example, lead to the printed circuit board being bent below the contact element. Also, the contact element may bend, and although in particular in the typical case in which its housing is made of plastic.

Wie sich herausgestellt hat weisen gattungsgemäße Anschlusselemente nach dem Verarbeitungsschritt bei erhöhter Temperatur häufig eine gebogene, beispielsweise kreisbogensegmentförmige Form auf. Dies beeinflusst auch die im Gehäuse eingebetteten Anschlussstifte, welche im Ausgangszustand typischerweise eine parallele Ausrichtung aufweisen. Aufgrund der Verbiegung des Gehäuses des Anschlusselements können die Anschlussstifte eine fächerförmige Ausrichtung aufweisen.As has been found, generic connection elements after the processing step at elevated temperature often on a curved, for example, circular arc segment-shaped form. This also affects the embedded in the housing pins, which typically have a parallel orientation in the initial state. Due to the bending of the housing of the connection element, the connection pins can have a fan-shaped orientation.

Aufgrund der genannten Verbiegungsvorgänge kann es problematisch oder unmöglich sein, gängige Stecker zu verwenden, welche zum Aufstecken auf das Anschlusselement vorgesehen sind und elektrische Kontakte zu einem Kabel herstellen können. Insbesondere die beschriebene fächerförmige Ausrichtung der Anschlussstifte passt nicht mehr zu solchen Steckern.Due to the aforementioned bending operations, it may be problematic or impossible to use common plugs which are provided for mounting on the connection element and can make electrical contacts to a cable. In particular, the described fan-shaped alignment of the pins no longer fits to such plugs.

Bei gattungsgemäßen Anschlusselementen können die beschriebenen Probleme beispielsweise dadurch gelöst werden, dass eine manuelle Überprüfung der Leiterplatten mit aufgebrachten Anschlusselementen erfolgt. Dies erfordert jedoch einen hohen Aufwand und führt dazu, dass zahlreiche Leiterplatten als Ausschuss aussortiert oder manuell korrigiert werden müssen. Um die beschriebenen Verbiegungsvorgänge zu verhindern wird bei gattungsgemäßen Anschlusselementen häufig ein Material für das Gehäuse verwendet, welches bei den im Verarbeitungsprozess auftretenden Temperaturen formstabil bleibt. Derartige Materialien, beispielsweise hochtemperaturbeständige Kunststoffe, sind jedoch sehr teuer.In the case of generic connection elements, the described problems can be solved, for example, by carrying out a manual examination of the printed circuit boards with applied connection elements. However, this requires a lot of effort and leads to the fact that numerous printed circuit boards must be sorted out as rejects or manually corrected. In order to prevent the described bending processes, a material for the housing is often used in generic connection elements, which remains dimensionally stable at the temperatures occurring in the processing process. However, such materials, such as high temperature resistant plastics, are very expensive.

Die Erfindung betrifft des Weiteren ein Verfahren zum Aufbringen eines Anschlusselements auf eine Leiterplatte sowie eine Leiterplatte, auf welcher ein Anschlusselement aufgebracht ist. Bei derartigen Verfahren und Leiterplatten treten die gleichen Probleme auf, wie sie eben mit Bezug auf das gattungsgemäße Anschlusselement beschrieben wurden.The invention further relates to a method for applying a connection element to a printed circuit board and a Printed circuit board on which a connection element is applied. In the case of such methods and printed circuit boards, the same problems occur as have just been described with reference to the generic connection element.

Es ist deshalb eine Aufgabe der Erfindung, ein Anschlusselement zum Aufbringen auf eine Leiterplatte vorzusehen, welches gegenüber gattungsgemäßen Anschlusselementen verbessert ist, insbesondere hinsichtlich seiner Stabilität bei hohen Temperaturen und/oder hinsichtlich der Kosten. Es ist des Weiteren eine Aufgabe der Erfindung, ein Verfahren zum Aufbringen eines solchen Anschlusselements auf eine Leiterplatte vorzusehen. Außerdem ist es eine Aufgabe der Erfindung, eine Leiterplatte vorzusehen, auf welcher ein solches Anschlusselement aufgebracht ist.It is therefore an object of the invention to provide a connection element for application to a printed circuit board, which is improved compared to generic connection elements, in particular with regard to its stability at high temperatures and / or in terms of cost. It is a further object of the invention to provide a method for applying such a connection element on a printed circuit board. In addition, it is an object of the invention to provide a printed circuit board on which such a connection element is applied.

Dies wird erfindungsgemäß durch ein Anschlusselement nach Anspruch 1, ein Verfahren nach Anspruch 13 und eine Leiterplatte nach Anspruch 14 gelöst. Vorteilhafte Ausgestaltungen können beispielsweise den jeweiligen Unteransprüchen entnommen werden. Der Inhalt der Ansprüche wird durch ausdrückliche Inbezugnahme zum Inhalt der Beschreibung gemacht.This is inventively achieved by a connection element according to claim 1, a method according to claim 13 and a circuit board according to claim 14. Advantageous embodiments can be taken, for example, the respective subclaims. The content of the claims is made by express reference to the content of the description.

Die Erfindung betrifft ein Anschlusselement zum Aufbringen auf eine Leiterplatte, aufweisend:

  • eine Anzahl von sich jeweils entlang einer Längsrichtung erstreckenden Anschlussstiften, und
  • ein Gehäuse, in welchem die Anschlussstifte enthalten sind.
The invention relates to a connection element for application to a printed circuit board, comprising:
  • a number of each extending along a longitudinal direction of pins, and
  • a housing in which the pins are included.

Erfindungsgemäß ist vorgesehen, dass zumindest einer der Anschlussstifte einen sich durch das Gehäuse quer zur Längsrichtung erstreckenden Stabilisierungsstab aufweist.According to the invention, at least one of the connecting pins has a stabilizing rod extending through the housing transversely to the longitudinal direction.

Mittels des Stabilisierungsstabs wird das Gehäuse stabilisiert. Durch die Ausrichtung quer zur Längsrichtung liegt ein solcher Stabilisierungsstab typischerweise im Wesentlichen parallel zu einer Leiterplatte, auf welcher das Anschlusselement aufgebracht ist, da die jeweiligen Anschlussstifte typischerweise senkrecht auf der Leiterplatte stehen. Somit wird mittels des Stabilisierungsstabs das Gehäuse gegenüber einem möglichen Durchbiegen der Leiterplatte und einer dazu korrespondierenden Verformung des Gehäuses stabilisiert. Auf die Verwendung besonders temperaturstabiler Materialien für das Gehäuse kann dabei verzichtet werden. Auch manuelles Kontrollieren und Korrigieren sind nicht mehr nötig. Somit wird auf einfache Weise eine Stabilisierung des Anschlusselements gegenüber Verformung erreicht, welche den Ausschuss deutlich verringert. Die Mehrkosten sind dabei erheblich niedriger als bei bekannten Anschlusselementen, deren Gehäuse aus temperaturstabilen Materialien besteht.The housing is stabilized by means of the stabilizing bar. Due to the orientation transverse to the longitudinal direction, such a stabilizing rod is typically substantially parallel to a printed circuit board on which the connecting element is applied, since the respective connecting pins are typically perpendicular to the printed circuit board. Thus, the housing is stabilized against a possible bending of the circuit board and a corresponding deformation of the housing by means of the stabilizing rod. The use of particularly temperature-stable materials for the housing can be dispensed with. Also manual control and correction are no longer necessary. Thus, a stabilization of the connection element against deformation is achieved in a simple manner, which significantly reduces the reject. The additional costs are considerably lower than with known connection elements whose housing consists of temperature-stable materials.

Es sei des Weiteren erwähnt, dass mittels des erfindungsgemäßen Anschlusselements auch nach dem Produktionsprozesses Vorteile erzielt werden. Insbesondere wird die Steifigkeit einer Leiterplatte oder einer anderen Komponente mit einem oder mehreren aufgebrachten erfindungsgemäßen Anschlusselementen dauerhaft erhöht. Dies erhöht die Resistenz sowohl gegen funktionelle Belastung, welche beispielsweise aus einer Einbausituation oder weiteren aufgebrachten Komponenten resultieren kann, wie auch gegen zufälligen Belastungen wie beispielsweise Vibrationen. Werden erfindungsgemäße Anschlusselemente beispielsweise auf eine rechteckige Leiterplatte aufgebracht, insbesondere eine Leiterplatte welche doppelseitig bestückt ist und lediglich vier Befestigungspunkte in den Ecken hat, so wird diese Leiterplatte weniger dazu neigen, sich während ihrer Lebensdauer zu verbiegen. Somit werden beispielsweise Anschlüsse in der Mitte der Leiterplatte weniger beansprucht, da sie nur kleineren räumlichen Veränderungen unterliegen. Auf Kompensationsstrukturen für räumliche Veränderungen kann verzichtet werden, insbesondere in der Mitte der Leiterplatte. Die Resistenz gegenüber Vibrationen kann mittels des erfindungsgemäßen Anschlusselements ebenfalls erhöht werden, so dass stärkeren Vibrationsprofilen Stand gehalten werden kann.It should also be mentioned that advantages are achieved by means of the connecting element according to the invention even after the production process. In particular, the rigidity of a printed circuit board or another component with one or more applied connecting elements according to the invention is permanently increased. This increases the resistance both against functional loading, which can result, for example, from a mounting situation or other applied components, as well as against accidental loads such as vibrations. If connecting elements according to the invention are applied, for example, to a rectangular printed circuit board, in particular a printed circuit board which is fitted on both sides and has only four attachment points in the corners, this printed circuit board will be less prone to bending during its service life. Thus, for example, connections in the center of the circuit board are less stressed, since they only smaller spatial Changes are subject. Compensation structures for spatial changes can be dispensed with, especially in the middle of the printed circuit board. The resistance to vibrations can also be increased by means of the connecting element according to the invention, so that stronger vibration profiles can be maintained.

Zudem ist es sogar möglich, mittels des erfindungsgemäßen Anschlusselements eine Resonanzfrequenz der resultierenden Kombination aus Leiterplatte und Anschlusselement bewusst einzustellen. Hierzu können beispielsweise eine oder mehrere erfindungsgemäße Anschlusselemente an bestimmten Positionen aufgebracht werden. Dies stellt insbesondere auch einen eigenständig zu verwirklichenden Aspekt der Erfindung dar. Dieser Aspekt kann auch mit anderen Elementen als Leiterplatten, auf welche erfindungsgemäße Anschlusselemente aufgebracht werden können, verwirklicht werden.In addition, it is even possible to deliberately set a resonance frequency of the resulting combination of printed circuit board and connecting element by means of the connecting element according to the invention. For this purpose, for example, one or more connecting elements according to the invention can be applied at specific positions. This also represents, in particular, an aspect of the invention which can be realized independently. This aspect can also be realized with elements other than printed circuit boards, to which connection elements according to the invention can be applied.

Die Anschlussstifte dienen typischerweise dazu, jeweils eine elektrisch leitende Verbindung zwischen einem auf das Anschlusselement mittels eines Steckers aufgesteckten Kabel und einer Leiterbahn auf der Leiterplatte herzustellen. Damit können beispielsweise logische Signale übertragen werden, Sensoren ausgelesen werden oder Versorgungsspannungen zur Verfügung gestellt werden. Jeder Anschlussstift überträgt dabei typischerweise ein Potential. Typischerweise handelt es sich bei dem verwendeten Kabel um ein mehradriges Kabel, beispielsweise um ein Flachbandkabel. In diesem Fall stellt typischerweise jeder Anschlussstift eine elektrisch leitende Verbindung zwischen einer Ader des Kabels und einer Leiterbahn auf der Leiterplatte her.The pins are typically used to each produce an electrically conductive connection between a plugged onto the connection element by means of a plug cable and a conductor track on the circuit board. Thus, for example, logical signals can be transmitted, sensors can be read out or supply voltages can be made available. Each pin typically transmits a potential. Typically, the cable used is a multi-core cable, such as a ribbon cable. In this case, typically each pin establishes an electrically conductive connection between a wire of the cable and a track on the board.

Derjenige Anschlussstift, welcher den Stabilisierungsstab aufweist, kann dabei ebenso wie die anderen zum Herstellen einer elektrisch leitenden Verbindung verwendet werden. Es kann jedoch alternativ auch der Anschlussstift, welcher den Stabilisierungsstab aufweist, nur zum Zweck der Stabilisierung im Anschlusselement enthalten sein. In diesem Fall wird über diesen Anschlussstift keine elektrisch leitende Verbindung hergestellt.The one pin, which has the stabilizing rod, can as well as the others for producing a electrically conductive connection can be used. However, alternatively, the terminal pin having the stabilizing bar may be included in the terminal only for the purpose of stabilization. In this case, no electrically conductive connection is made via this pin.

Es sei verstanden, dass sich die Längsrichtung eines Anschlussstifts typischerweise auf denjenigen Bestandteil des Anschlussstifts bezieht, welcher zum Herstellen einer elektrisch leitenden Verbindung vorgesehen ist. Bei Anschlussstiften, welche keinen Stabilisierungsstab aufweisen, kann der gesamte Anschlussstift die Längsrichtung definieren. Bei Anschlussstiften, welche einen Stabilisierungsstab aufweisen, wird die Längsrichtung typischerweise durch einen bei gedachter Entfernung des Stabilisierungsstabs übrigbleibenden Bestandteil definiert.It should be understood that the longitudinal direction of a terminal pin typically refers to that part of the terminal pin which is provided for producing an electrically conductive connection. For pins that do not have a stabilizer bar, the entire pin can define the lengthwise direction. For pins having a stabilizer bar, the longitudinal direction is typically defined by a remnant of the stabilizer bar when removed.

Die Integration der Anschlussstifte samt dem Stabilisierungsstab in ein von der Leiterplatte getrennten Gehäuse vereinfacht u. a. die Herstellung und Handhabung bei der Montage des Anschlusselements. Je nach Anwendungsfall ist es aber auch denkbar, Abschnitte oder Teile der Leiterplatte als Gehäuse zu verwenden und insbesondere den Stabilisierungsstab in die Leiterplatte direkt zu integrieren. Ferner ist es denkbar das Gehäuse aus einem eigenständigen Teil und einem Teil der Leiterplatte zusammenzusetzen.The integration of the pins together with the stabilizing rod in a separate housing of the circuit board simplifies u. a. the manufacture and handling during assembly of the connection element. Depending on the application, it is also conceivable to use sections or parts of the printed circuit board as a housing and in particular to integrate the stabilization bar directly into the printed circuit board. Furthermore, it is conceivable to assemble the housing from an independent part and a part of the printed circuit board.

Gemäß einer Ausführung weist zumindest ein weiterer Anschlussstift einen sich durch das Gehäuse quer zur Längsrichtung erstreckenden weiteren Stabilisierungsstab auf. Dann sind in dem Anschlusselement zwei Stabilisierungsstäbe vorhanden. Die Längsrichtung, zu welcher sich der weitere Stabilisierungsstab quer erstreckt, ist in diesem Fall typischerweise diejenige des weiteren Anschlussstifts.According to one embodiment, at least one further connecting pin has a further stabilizing rod extending through the housing transversely to the longitudinal direction. Then there are two stabilizing bars in the connecting element. The longitudinal direction, to which the further stabilizing rod extends transversely, in this case is typically that of the other pin.

Es sei verstanden, dass auch eine beliebige höhere Anzahl von Stabilisierungsstäben verwendet werden kann. Auch diese können jeweils so ausgebildet sein, dass ein jeweiliger Anschlussstift den jeweiligen Stabilisierungsstab aufweist, und sie können sich jeweils quer zur Längsrichtung dieses Anschlussstifts erstrecken. Es ist zudem möglich, dass ein jeweiliger Anschlussstift mehrere Stabilisierungsstäbe aufweist.It should be understood that any higher number of stabilizing bars may be used. These can each be designed so that a respective pin has the respective stabilizing rod, and they can each extend transversely to the longitudinal direction of this pin. It is also possible that a respective connecting pin has a plurality of stabilizing rods.

Auch der weitere Anschlussstift, welcher den weiteren Stabilisierungsstab aufweist, kann so ausgebildet sein, dass er zum Herstellen einer elektrisch leitenden Verbindung verwendet wird. Er kann jedoch auch so ausgeführt sein, dass er nur zum Zweck der Stabilisierung vorhanden ist und somit keine elektrisch leitende Verbindung herstellt. Gleiches gilt für alle möglichen Anschlussstifte mit Stabilisierungsstäben.The further connecting pin, which has the further stabilizing rod, can also be designed such that it is used to produce an electrically conductive connection. However, it can also be designed so that it is present only for the purpose of stabilization and thus does not produce an electrically conductive connection. The same applies to all possible pins with stabilizing bars.

Gemäß einer Ausführung sind der Stabilisierungsstab und der weitere Stabilisierungsstab parallel zueinander ausgerichtet. Damit können beide Stabilisierungsstäbe gleichmäßig formstabilisierend auf das Anschlusselement wirken. Anders ausgedrückt verstärkt sich die Wirkung der beiden Stabilisierungsstäbe. Zudem kann eine bessere Verteilung der Stabilisierungswirkung beispielsweise über eine Richtung quer zu einer Längserstreckung der Stabilisierungsstäbe erreicht werden. Auf diese Weise kann eine besonders gute Stabilisierungswirkung mit relativ dünnen Stabilisierungsstäben erreicht werden. Dieser Fall ist dann besonders vorteilhaft, wenn man die Stabilisierungsstäbe in dünne Leiterplatten integrieren möchte.According to one embodiment, the stabilizing bar and the further stabilizing bar are aligned parallel to one another. Thus, both stabilizing bars can act evenly stabilize the shape of the connection element. In other words, the effect of the two stabilizing bars increases. In addition, a better distribution of the stabilizing effect can be achieved, for example, via a direction transverse to a longitudinal extent of the stabilizing rods. In this way, a particularly good stabilizing effect can be achieved with relatively thin stabilizing rods. This case is particularly advantageous if you want to integrate the stabilization rods in thin circuit boards.

Gemäß einer Ausführung haben der Stabilisierungsstab und der weitere Stabilisierungsstab jeweilige freie Enden, welche in zueinander entgegengesetzte Richtungen weisen. Dies erlaubt eine Ausführung, in welcher die beiden Anschlussstifte, an welchen die Stabilisierungsstäbe angebracht sind, voneinander beabstandet sind, wobei insbesondere der Zwischenraum zwischen diesen beiden Anschlussstiften von den Stabilisierungsstäben gemeinsam stabilisiert wird.According to one embodiment, the stabilizing bar and the further stabilizing bar have respective free ends, which in have opposite directions to each other. This allows an embodiment in which the two pins on which the stabilizing rods are mounted, are spaced apart, in particular, the gap between these two pins is stabilized together by the stabilizing rods.

Gemäß einer Ausführung sind der Stabilisierungsstab und der weitere Stabilisierungsstab zumindest teilweise nebeneinander angeordnet. Damit können ebenfalls eine vorteilhafte Verstärkung und eine Vergleichmäßigung der Stabilisierungswirkung erreicht werden.According to one embodiment, the stabilizing bar and the further stabilizing bar are arranged at least partially next to one another. Thus, an advantageous gain and equalization of the stabilization effect can also be achieved.

Gemäß einer Ausführung sind

  • die Anschlussstifte in einer ersten Gruppe und einer zweiten Gruppe angeordnet, welche voneinander beabstandet sind,
  • wobei der Stabilisierungsstab an demjenigen Anschlussstift der ersten Gruppe ausgebildet ist, welcher am nächsten zur zweiten Gruppe angeordnet ist,
  • und wobei der weitere Stabilisierungsstab an demjenigen Anschlussstift der zweiten Gruppe ausgebildet ist, welcher am nächsten zur ersten Gruppe angeordnet ist.
According to one embodiment are
  • the pins are arranged in a first group and a second group, which are spaced from each other,
  • wherein the stabilizing bar is formed on the pin of the first group, which is arranged closest to the second group,
  • and wherein the further stabilizing bar is formed on the pin of the second group, which is arranged closest to the first group.

Eine solche Ausführung erlaubt die Anpassung des erfindungsgemäßen Anschlusselements an typische Gestaltungen bekannter Anschlusselemente und hat sich hinsichtlich der Stabilisierungswirkung als vorteilhaft erwiesen.Such an embodiment allows the adaptation of the connection element according to the invention to typical designs of known connection elements and has proven to be advantageous with regard to the stabilization effect.

Gemäß einer Ausführung erstrecken sich der Stabilisierungsstab und/oder der weitere Stabilisierungsstab jeweils an einer Anzahl von Anschlussstiften vorbei. Damit kann eine Stabilisierungswirkung des jeweiligen Stabilisierungsstabs auch über einen Bereich des Anschlusselements hinweg, in welchem Anschlussstifte ausgebildet sind, erzielt werden.According to one embodiment, the stabilizing bar and / or the further stabilizing bar each extend past a number of connecting pins. Thus, a stabilizing effect of the respective stabilizing bar can also be achieved over a region of the connecting element in which connecting pins are formed.

Bevorzugt sind die Anschlussstifte parallel zueinander ausgerichtet. Dies ermöglicht ein einfaches Aufstecken eines Steckers auf das Anschlusselement.Preferably, the pins are aligned parallel to each other. This allows a simple plugging a plug on the connection element.

Bevorzugt ist das Anschlusselement als Surface-Mounted Device (SMD) - Anschlusselement ausgeführt. Bei einer solchen Ausführung kommen die erwähnten Vorteile besonders zur Geltung, weil SMD-Anschlusselemente typischerweise in einem Verfahren auf eine Leiterplatte aufgebracht werden, welches zumindest einen Hochtemperaturschritt beinhaltet. Bei solchen Hochtemperaturschritten ist die Gefahr einer Verbiegung besonders hoch.Preferably, the connection element is designed as a surface-mounted device (SMD) - connection element. In such an embodiment, the mentioned advantages come into their own, because SMD connection elements are typically applied to a printed circuit board in a method which includes at least one high-temperature step. At such high temperature steps, the risk of bending is particularly high.

Bevorzugt sind die Anschlussstifte in dem Gehäuse eingegossen. Dies ermöglicht eine einfache Herstellung und eine zuverlässige, spielfreie Halterung der Anschlussstifte.Preferably, the pins are cast in the housing. This allows for easy production and a reliable, play-free mounting of the pins.

Bevorzugt sind die jeweiligen Anschlussstifte jeweils einstückig und weiter bevorzugt aus Metall ausgebildet. Dabei kann es sich beispielsweise um Kupfer, Aluminium, um ein anderes leitfähiges Metall oder um eine Legierung aus solchen Metallen handeln. Es kann insbesondere vorgesehen sein, dass auch die jeweiligen Anschlussstäbe, an welchen ein Stabilisierungsstab angebracht ist, einstückig ausgebildet sind. Dies ermöglicht ein einfaches Herstellen des jeweiligen Anschlussstifts mit seinem Stabilisierungsstab durch Verwenden einer entsprechenden Form. Auch die weiteren Verarbeitungsschritte beim Herstellen des Anschlusselements können vereinfacht werden, weil die Stabilisierungsstäbe zusammen mit ihren Anschlusselementen an die vorgesehenen Positionen gesetzt werden können, ohne dass hierfür zusätzliche Schritte oder Apparaturen notwendig wären.Preferably, the respective pins are each integrally formed and more preferably made of metal. This may be, for example, copper, aluminum, another conductive metal or an alloy of such metals. It can be provided in particular that the respective connecting rods, to which a stabilizing rod is attached, are integrally formed. This allows easy manufacture of the respective terminal pin with its stabilizing rod by using a corresponding shape. The further processing steps in the manufacture of the connecting element can be simplified because the stabilizing rods can be set together with their connecting elements to the intended positions, without the need for additional steps or equipment would be necessary.

Bevorzugt sind die Anschlussstifte elektrisch gegeneinander isoliert. Dies kann beispielsweise durch die bereits erwähnte eingegossene Halterung in dem Gehäuse erfolgen, welches typischerweise aus nicht elektrisch leitfähigem Kunststoff besteht. Somit kann jeder Anschlussstift genau ein Potential unabhängig von anderen Potentialen aufweisen und eine eigenständige elektrische Verbindung herstellen.Preferably, the pins are electrically isolated from each other. This can for example be done by the already mentioned cast-in holder in the housing, which typically made of non-electrically conductive plastic. Thus, each pin can have exactly one potential independent of other potentials and establish a self-contained electrical connection.

Die Erfindung betrifft des Weiteren ein Verfahren zum Aufbringen eines Anschlusselements auf eine Leiterplatte, welches folgende Schritte aufweist:

  • Bereitstellen einer Leiterplatte mit einer Anbringstelle für ein Anschlusselement,
  • Bereitstellen eines erfindungsgemäßen Anschlusselements,

  • Heating the circuit board with the connection element.

Mittels des erfindungsgemäßen Verfahrens kann durch die Verwendung eines erfindungsgemäßen Anschlusselements ein Vorteil bei der Verfahrensführung erreicht werden. Insbesondere kann das Erzeugen von Ausschussware aufgrund eines Durchbiegens der Leiterplatte bei hohen Temperaturen vermieden werden, ohne dass hierfür auf besonders teure Materialien für das Gehäuse des Anschlusselements zurückgegriffen werden muss.By means of the method according to the invention, an advantage in the process control can be achieved by the use of a connection element according to the invention. In particular, the production of rejects due to bending of the printed circuit board at high temperatures can be avoided without having to resort to particularly expensive materials for the housing of the connection element.

Fig. 1 zeigt eine Leiterplatte 10, welche auf einer ersten Schiene 20 und einer zweiten Schiene 22 gelagert ist. Die Schienen 20, 22 sind nicht Bestandteil der Leiterplatte 10. Fig. 1 shows a printed circuit board 10 which is mounted on a first rail 20 and a second rail 22. The rails 20, 22 are not part of the circuit board 10th

Auf der Leiterplatte 10 ist ein Anschlusselement 100 gemäß dem Stand der Technik aufgebracht, welches ein Gehäuse 105 aus Kunststoff sowie eine Anzahl von Anschlussstiften aus Metall aufweist. Dabei handelt es sich um einen ersten Anschlussstift 111, einen zweiten Anschlussstift 112, einen dritten Anschlussstift 113, einen vierten Anschlussstift 114, einen fünften Anschlussstift 115, einen sechsten Anschlussstift 116, einen siebten Anschlussstift 121, einen achten Anschlussstift 122, einen neunten Anschlussstift 123, einen zehnten Anschlussstift 124, einen elften Anschlussstift 125 und einen zwölften Anschlussstift 126.On the circuit board 10, a connection element 100 according to the prior art is applied, which has a housing 105 made of plastic and a number of pins made of metal. These are a first connection pin 111, a second connection pin 112, a third connection pin 113, a fourth pin 114, a fifth pin 115, a sixth pin 116, a seventh pin 121, an eighth pin 122, a ninth pin 123, a tenth pin 124, an eleventh pin 125, and a twelfth pin 126.

Um das Anschlusselement 100 auf die Leiterplatte 10 aufzubringen wurden beide zusammen einem Verarbeitungsschritt bei so hoher Temperatur ausgesetzt, dass die Materialien des Gehäuses 105 und der Leiterplatte 10 ihre Festigkeit nicht mehr ausreichend aufrechterhalten konnten, um die Formen des Gehäuses 105 und der Leiterplatte 10 stabil zu halten. Vielmehr hat sich die Leiterplatte 10, wie in Fig. 1 gezeigt, in der Mitte nach unten durchgebogen, wobei sich die Form des Gehäuses 105 entsprechend angepasst hat. Da eine ursprünglich gerade Form des Gehäuses 105 auf diese Weise in eine leicht gebogene, also kreisbogensegmentförmige Form des Gehäuses 105 übergegangen ist, und die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 in dem Gehäuse 105 eingebettet sind, haben sich dabei auch die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 verbogen, so dass sie nicht mehr wie ursprünglich parallel zueinander ausgerichtet, sondern jeweils quer zu einem gedachten Kreisbogensegment mit großem Radius stehen. Anders ausgedrückt sind sie fächerförmig angeordnet. Dies kann das Aufstecken eines Steckers auf das Anschlusselement 100 erschweren oder gar verhindern.To apply the terminal member 100 to the circuit board 10, both were subjected to a processing step at such a high temperature that the materials of the housing 105 and the circuit board 10 could no longer sufficiently maintain their strength to stably secure the shapes of the housing 105 and the circuit board 10 hold. Rather, the circuit board 10, as in Fig. 1 shown, bent in the middle down, with the shape of the housing 105 has adapted accordingly. Since an originally straight shape of the housing 105 has thus merged into a slightly curved, ie arc-segment-shaped form of the housing 105, and the connection pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 are embedded in the housing 105, this also the terminal pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 have been bent so that they are no longer aligned as originally parallel to each other, but each transverse to an imaginary circular arc segment with a large radius. In other words, they are arranged in a fan shape. This can complicate or even prevent the plugging of a plug onto the connection element 100.

Fig. 2 zeigt ein Anschlusselement 100 gemäß einem ersten Ausführungsbeispiel der Erfindung. Dabei ist in Fig. 2 eine Schnittansicht dargestellt. Fig. 2 shows a connection element 100 according to a first embodiment of the invention. It is in Fig. 2 a sectional view shown.

Das Anschlusselement 100 weist ein Gehäuse 105 auf. In diesem sind eine erste Gruppe 110 von Anschlussstiften und eine zweite Gruppe 120 von Anschlussstiften ausgebildet. Die erste Gruppe 110 von Anschlussstiften weist einen ersten Anschlussstift 111, einen zweiten Anschlussstift 112, einen dritten Anschlussstift 113, einen vierten Anschlussstift 114, einen fünften Anschlussstift 115 und einen sechsten Anschlussstift 116 auf. Die zweite Gruppe 120 von Anschlussstiften weist einen siebten Anschlussstift 121, einen achten Anschlussstift 122, einen neunten Anschlussstift 123, einen zehnten Anschlussstift 124, einen elften Anschlussstift 125 und einen zwölften Anschlussstift 126 auf. Die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 sind in dem Gehäuse 105 eingebettet, was vorliegend dadurch erreicht wird, dass die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 in dem Gehäuse 105 eingegossen sind. Dies ermöglicht eine vollständig umschließende und elektrisch isolierende Halterung der Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126.The connection element 100 has a housing 105. In this are a first group 110 of pins and a second group 120 formed by pins. The first group 110 of pins has a first pin 111, a second pin 112, a third pin 113, a fourth pin 114, a fifth pin 115, and a sixth pin 116. The second group 120 of pins has a seventh pin 121, an eighth pin 122, a ninth pin 123, a tenth pin 124, an eleventh pin 125 and a twelfth pin 126. The connection pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 are embedded in the housing 105, which is achieved here in that the connection pins 111, 112, 113, 114, 115 , 116, 121, 122, 123, 124, 125, 126 are cast in the housing 105. This allows a completely enclosing and electrically insulating mounting of the connection pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126.

Der zehnte Anschlussstift 124 weist einen Stabilisierungsstab 129 auf. Dieser ist materialeinheitlich mit dem restlichen Teil des zehnten Anschlussstifts 124 ausgebildet. Der Stabilisierungsstab 129 erstreckt sich quer zu einer Längsrichtung des zehnten Anschlussstifts 124 und erstreckt sich somit durch das Gehäuse 105 und an dem ersten Anschlussstift 111, dem zweiten Anschlussstift 112, dem dritten Anschlussstift 113, dem siebten Anschlussstift 121, dem achten Anschlussstift 122 und dem neunten Anschlussstift 123 vorbei. Der Stabilisierungsstab 129 erstreckt sich dabei parallel zu einer in Fig. 2 nicht dargestellten Leiterplatte, auf welche das Anschlusselement 100 aufzubringen ist.The tenth pin 124 has a stabilizing bar 129. This is formed of the same material with the remaining part of the tenth terminal pin 124. The stabilizing bar 129 extends transversely to a longitudinal direction of the tenth terminal pin 124 and thus extends through the housing 105 and on the first pin 111, the second pin 112, the third pin 113, the seventh pin 121, the eighth pin 122 and the ninth Pin 123 over. The stabilizing rod 129 extends parallel to an in Fig. 2 not shown, on which the connection element 100 is to be applied.

Auch der Stabilisierungsstab 129 wird von dem Gehäuse 105 allseitig und anliegend umschlossen. Somit wirkt der Stabilisierungsstab 129 stabilisierend auf das Gehäuse 105 und verhindert insbesondere die in Fig. 1 gezeigte Verbiegung. Auf diese Weise bleibt das Gehäuse 105 auch bei höheren Temperaturen stabil in Form, bei welchen die eigene Stabilität des Gehäuses 105 nicht mehr zur Verhinderung einer Durchbiegung ausreichen würde. Die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 behalten somit ihre parallele Ausrichtung bei, was die ansonsten auftretenden, bereits beschriebenen Probleme vermeidet.Also, the stabilizing rod 129 is enclosed by the housing 105 on all sides and adjacent. Thus, the stabilizing rod 129 acts stabilizing on the housing 105 and in particular prevents the in Fig. 1 shown bending. On In this way, the housing 105 remains stable even at higher temperatures, in which the own stability of the housing 105 would no longer be sufficient to prevent deflection. The pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 thus maintain their parallel alignment, which avoids the otherwise occurring problems already described.

Fig. 3 zeigt eine Draufsicht auf das Anschlusselement 100, wobei die eingezeichnete Linie A-A den Schnitt anzeigt, welcher die Grundlage für die Darstellung von Fig. 1 bildet. Die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 sind in Fig. 3 von oben zu sehen. Fig. 3 shows a plan view of the connection element 100, wherein the drawn line AA indicates the section, which is the basis for the representation of Fig. 1 forms. The terminal pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 are in FIG Fig. 3 to be seen from above.

Fig. 4 zeigt das Anschlusselement 100 in einer gekippten Ansicht. Da es sich hierbei nicht um eine Schnittansicht handelt, ist der Stabilisierungsstab 129 nicht zu sehen.

This is located inside the housing 105.

Fig. 5 zeigt das Anschlusselement 100 in einer nochmals anderen Darstellung. Im Vergleich zu Fig. 2 ist das Anschlusselement 100 dabei um eine horizontale Achse gekippt. Da es sich ebenfalls nicht um eine Schnittansicht handelt, ist der Stabilisierungsstab 129 auch in Fig. 5 nicht zu sehen. Fig. 5 shows the connection element 100 in yet another illustration. Compared to Fig. 2 the connection element 100 is tilted about a horizontal axis. Since it is also not a sectional view, the stabilizing rod 129 is also in Fig. 5 not to be seen.

Fig. 6 zeigt ein Anschlusselement 100 gemäß einem zweiten Ausführungsbeispiel der Erfindung. Bezüglich des Gehäuses 105 und der Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 kann dabei weitgehend auf Fig. 2 und die zugehörige Beschreibung verwiesen werden. Nachfolgend wird deshalb vorwiegend auf die Unterschiede eingegangen. Bei Fig. 6 handelt es sich um eine Draufsicht, wobei einzelne Elemente innerhalb des Gehäuses 105 gestrichelt dargestellt sind. Fig. 6 shows a connection element 100 according to a second embodiment of the invention. With respect to the housing 105 and the pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 can thereby largely on Fig. 2 and the associated description. In the following, therefore, the differences will mainly be discussed. at Fig. 6 it is a plan view, with individual elements within the housing 105 are shown in dashed lines.

Im Unterschied zu der Ausführung von Fig. 2 weist das Anschlusselement 100 gemäß dem in Fig. 6 dargestellten zweiten Ausführungsbeispiel einen ersten Stabilisierungsstab 119 und einen zweiten Stabilisierungsstab 129 auf. Dabei weist der erste Anschlussstift 111 den ersten Stabilisierungsstab 119 auf, und der siebte Anschlussstift 121 weist den zweiten Stabilisierungsstab 129 auf. Der zehnte Stabilisierungsstab 124 weist im Unterschied zum ersten Ausführungsbeispiel keinen Stabilisierungsstab auf.Unlike the execution of Fig. 2 has the connection element 100 according to the in Fig. 6 illustrated second embodiment, a first stabilizing rod 119 and a second stabilizing rod 129. In this case, the first connection pin 111 has the first stabilization bar 119, and the seventh connection pin 121 has the second stabilization bar 129. The tenth stabilizing bar 124, unlike the first embodiment, has no stabilizing bar.

Die Stabilisierungsstäbe 119, 129 sind parallel zueinander und auf gleicher Höhe ausgerichtet. Der erste Stabilisierungsstab 119 erstreckt sich vorbei an dem siebten Anschlussstift 121, dem achten Anschlussstift 122 und dem neunten Anschlussstift 123. Der zweite Stabilisierungsstab 129 erstreckt sich vorbei an dem ersten Anschlussstift 111, dem zweiten Anschlussstift 112 und dem dritten Anschlussstift 113. Abschnittsweise erstrecken sich die Stabilisierungsstäbe 119, 129 auch aneinander vorbei.The stabilizing bars 119, 129 are aligned parallel to each other and at the same height. The first stabilizing bar 119 extends past the seventh pin 121, the eighth pin 122, and the ninth pin 123. The second stabilizer bar 129 extends past the first pin 111, the second pin 112, and the third pin 113 Stabilizing rods 119, 129 also past each other.

Durch die Stabilisierungsstäbe 119, 129 wird das Gehäuse 105 jeweils gegen ein Durchbiegen stabilisiert. Durch die Verwendung zweier Stabilisierungsstäbe 119, 129 wird der Stabilisierungseffekt sogar noch verbessert und gleichmäßiger verteilt.By the stabilizing rods 119, 129, the housing 105 is stabilized against bending. By using two stabilizing rods 119, 129, the stabilizing effect is even improved and distributed more evenly.

Fig. 7 zeigt das Anschlusselement 100 von Fig. 6 in einer anderen Ansicht, wobei diese leicht verkippt ist. Die Stabilisierungsstäbe 119, 129 sind in Fig. 7 nicht zu sehen, da sich diese innerhalb des Gehäuses 105 befinden. Fig. 7 shows the connection element 100 of Fig. 6 in another view, which is slightly tilted. The stabilizing bars 119, 129 are in Fig. 7 not to be seen, since they are located within the housing 105.

Fig. 8 zeigt eine Schnittansicht des Anschlusselements 100 von Fig. 6 gemäß der in Fig. 6 dargestellten Schnittlinie B-B. Dabei sind die Anschlussstifte 121, 122, 123, 124, 125, 126 der zweiten Gruppe 120 von Anschlussstiften gezeigt. Insbesondere ist zu sehen, dass der siebte Anschlussstift 121 den zweiten Stabilisierungsstab 129 aufweist, welcher sich quer zur Längsrichtung des siebten Anschlussstifts 121 durch das Gehäuse 105 erstreckt. Fig. 8 shows a sectional view of the connection element 100 of Fig. 6 according to the in Fig. 6 illustrated section line BB. In this case, the connection pins 121, 122, 123, 124, 125, 126 of the second group 120 of connection pins are shown. In particular, it can be seen that the seventh pin 121 is the second stabilizer bar 129, which extends transversely to the longitudinal direction of the seventh connection pin 121 through the housing 105.

Fig. 9 zeigt eine Schnittansicht des Anschlusselements 100 von Fig. 6 gemäß der in Fig. 6 dargestellten Schnittlinie C-C. Dabei sind die Anschlussstifte 111, 112, 113, 114, 115, 116 der ersten Gruppe 110 von Anschlussstiften gezeigt. Insbesondere ist dargestellt, dass der erste Anschlussstift 111 den ersten Stabilisierungsstab 119 aufweist. Dieser erstreckt sich quer zur Längsrichtung des ersten Anschlussstifts 111 durch das Gehäuse 105. Fig. 9 shows a sectional view of the connection element 100 of Fig. 6 according to the in Fig. 6 illustrated section line CC. In this case, the connection pins 111, 112, 113, 114, 115, 116 of the first group 110 of connection pins are shown. In particular, it is shown that the first connection pin 111 has the first stabilizing rod 119. This extends transversely to the longitudinal direction of the first connection pin 111 through the housing 105.

Insbesondere ist in den Fig. 8 und 9 auch zu erkennen, dass die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 in das Gehäuse 105 eingebettet sind. Dies ermöglicht eine vorteilhafte Stabilisierung und Kraftübertragung, beispielsweise zur Erreichung der Stabilisierungswirkung mittels der Stabilisierungsstäbe 119, 129.In particular, in the Fig. 8 and 9 It can also be seen that the connection pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 are embedded in the housing 105. This makes possible an advantageous stabilization and force transmission, for example for achieving the stabilizing effect by means of the stabilizing rods 119, 129.

Fig. 10 zeigt die Anschlussstifte 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 des Anschlusselements 100 von Fig. 6 ohne das Gehäuse 105. Dabei ist insbesondere zu sehen, wie die beiden Stabilisierungsstäbe 119, 129 relativ zu den Anschlussstiften 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 angeordnet sind. Auch ist zu sehen, dass die Stabilisierungsstäbe 119, 129 auf gleicher Höhe und parallel zueinander ausgerichtet sind. Jeweilige freie Enden der Stabilisierungsstäbe 119, 129 weisen in gegenüberliegende Richtungen. Fig. 10 shows the connection pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126 of the connection element 100 of FIG Fig. 6 without the housing 105. In particular, it can be seen how the two stabilizing bars 119, 129 are arranged relative to the connecting pins 111, 112, 113, 114, 115, 116, 121, 122, 123, 124, 125, 126. It can also be seen that the stabilizing rods 119, 129 are aligned at the same height and parallel to one another. Respective free ends of the stabilizing bars 119, 129 face in opposite directions.

Fig. 11 zeigt eine Leiterplatte 10 gemäß einem Ausführungsbeispiel der Erfindung. Die Leiterplatte 10 liegt auf einer ersten Schiene 20 und einer zweiten Schiene 22 auf, wie dies typischerweise nach einem Verarbeitungsschritt mit hoher Temperatur der Fall ist. Auf der Leiterplatte 10 ist ein Anschlusselement 100 gemäß dem zweiten Ausführungsbeispiel, welches in den Fig. 6 bis 10 dargestellt ist, aufgebracht. Aufgrund der enthaltenen Stabilisierungsstäbe 119, 129 wird ein Durchbiegen der Leiterplatte 10 auch bei Verarbeitungsschritten, welche bei hoher Temperatur durchgeführt werden, zuverlässig vermieden. Somit ist die Leiterplatte 10 vorliegend nicht durchgebogen, sondern hat ihre gewünschte ebene Form beibehalten. Fig. 11 shows a printed circuit board 10 according to an embodiment of the invention. The circuit board 10 rests on a first rail 20 and a second rail 22, as is typically the case after a high temperature processing step. On the circuit board 10 is a connection element 100 according to the second embodiment, which in the Fig. 6 to 10 is shown applied. Due to the included stabilizing bars 119, 129, sagging of the printed circuit board 10 is reliably avoided even during processing steps which are carried out at high temperature. Thus, the circuit board 10 is not bent in the present case, but has retained its desired planar shape.
