Description
Die Erfindung betrifft einen Steckverbinder zur Montage auf einer Leiterplatte, mit einem Trägerkörper, mindestens einem Oberflächenmontage-Kontaktelement, das in dem Trägerkörper angeordnet ist, und mindestens einem Durchsteckmontage-Kontaktelement, das ebenfalls in dem Trägerkörper angeordnet ist.The invention relates to a connector for mounting on a printed circuit board, comprising a carrier body, at least one surface-mounted contact element, which is arranged in the carrier body, and at least one push-through contact element, which is also arranged in the carrier body.
Bekannt sind Steckverbinder, deren Kontaktelemente als Durchsteckmontage-Kontaktelementen ausgebildet sind, also in eine Bohrung durch die Leiterbahn der Leiterplatte eingesteckt werden. Dadurch ergibt sich eine hohe mechanische Festigkeit der Verbindung zwischen Leiterplatte und Kontaktelement des Steckverbinders.Connectors are known whose contact elements are formed as through-hole contact elements, so are inserted into a hole through the conductor of the circuit board. This results in a high mechanical strength of the connection between the printed circuit board and the contact element of the connector.
Bekannt sind auch Steckverbinder, deren Kontaktelemente als Oberflächenmontage-Kontaktelemente ausgebildet sind, also auf die Leiterbahn aufgelötet werden. Die sich dabei ergebende Lötstelle bietet nur eine vergleichsweise geringe mechanische Festigkeit, insbesondere bei Scherbelastungen. Allerdings läßt sich eine höhere Signalübertragungsgeschwindigkeit zwischen Kontaktelement und Leiterbahn erzielen.Also known are connectors whose contact elements are designed as surface-mounted contact elements, so are soldered onto the conductor track. The resulting solder joint offers only a comparatively low mechanical strength, especially with shear loads. However, a higher signal transmission speed between contact element and conductor can be achieved.
Aus der DE-A-39 26 802 ist ein elektrischer Steckverbinder für Leiterplatten bekannt, bei dem in einem isolierenden Gehäuse eine Vielzahl elektrischer Kontakte vorgesehen ist, wobei mindestens ein Kontakt als Preßsitzkontakt in einem durchkontaktierten Loch der Leiterplatte und zumindest ein weiterer Kontakt als Anlagekontakt an der Oberfläche der Leiterplatte als Anlege-Kontakt ausgebildet ist.From DE-A-39 26 802 an electrical connector for printed circuit boards is known, in which an insulating housing a plurality of electrical contacts is provided, wherein at least one contact as a press-fit contact in a plated-through hole of the circuit board and at least one other contact as an abutment contact the surface of the circuit board is formed as a contact contact.
Weiterhin ist aus der DE-A-19604432 eine Anordnung zur Kontaktierung einer Leiterplatte mit einem Stecker in Hybridtechnik ausgebildet, bei dem lange Kontaktstifte, die in Durchbrüche der Leiterplatte eingebracht sind, Zugkräfte für die Anpressung von kurzen Kontaktstiften auf Kontaktierungsflächen aufbringen, die auf der Oberfläche der Leiterplatte angeordnet sind.Furthermore, from DE-A-19604432 an arrangement for contacting a printed circuit board with a plug in hybrid technology is formed, in which long contact pins, which are introduced in openings of the printed circuit board, apply tensile forces for the contact pressure of short contact pins on contacting surfaces on the surface the circuit board are arranged.
Die Aufgabe der Erfindung besteht darin, einen Steckverbinder zu schaffen, der bei hoher Signalübertragungsgeschwindigkeit eine Verbindung zwischen Leiterplatte und Steckverbinder mit hoher mechanischer Festigkeit ermöglicht, wobei gleichzeitig verschiebbare Anschlusselemente vorgesehen sind, die bei Leiterplatten auftretende Oberflächentoleranzen ausgleichen.The object of the invention is to provide a connector which allows high signal transmission speed at a connection between the printed circuit board and connector with high mechanical strength, at the same time slidable connection elements are provided which compensate for PCB surface tolerances occur.
Diese Aufgabe wird dadurch gelöst, daß das Oberflächenmontage-Kontaktelement mit einem Anschlußbereich versehen ist, auf dem ein Anschlußelement angeordnet ist, das relativ zu dem Anschlußbereich verschiebbar ist.This object is achieved in that the surface mount contact element is provided with a connection region on which a connection element is arranged, which is displaceable relative to the connection region.
Vorzugsweise ist das Durchsteckmontage-Kontaktelement ein Massekontakt. Diese Gestaltung ist vorteilhaft, da sich dann die niedrigere Signalübertragungsgeschwindigkeit kaum auswirkt. Das Durchsteckmontage-Kontaktelement kann auch allgemein zur Signalübertragung bei Signalen verwendet werden, die eine niedrige Frequenz haben.Preferably, the through-hole contact element is a ground contact. This design is advantageous because then the lower signal transmission speed hardly affects. The push-through contact element may also be used generally for signal transmission on signals having a low frequency.
Vorzugsweise ist weiterhin vorgesehen, daß vier Oberflächenmontage-Kontaktelemente und ein Durchsteckmontage-Kontaktelement vorgesehen sind, wobei die Oberflächenmontage-Kontaktelemente in zwei Gruppen angeordnet sind, die durch das Durchsteckmontage-Kontaktelement voneinander getrennt sind. Bei dieser Gestaltung dient das Durchsteckmontage-Kontaktelement als Abschirmung zwischen den beiden Gruppen von Oberflächenmontage-Kontaktelementen, die zur Signalübertragung verwendet werden, so daß sich eine hohe Übersprech-Dämpfung ergibt.Preferably, it is further provided that four surface-mounted contact elements and a through-hole contact element are provided, wherein the surface-mounted contact elements are arranged in two groups, which are separated from each other by the through-hole contact element. In this design, the through-hole contact element serves as a shield between the two sets of surface-mount contact elements used for signal transmission, resulting in high crosstalk attenuation.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß das Oberflächenmontage-Kontaktelement mit einem Anschlußbereich versehen ist, auf dem ein Anschlußelement angeordnet ist, das relativ zu dem Anschlußbereich verschiebbar ist. Diese Gestaltung ermöglicht es, die bei der Oberflächenmontagetechnik kritische Dicke des Lötpolsters zwischen dem Oberflächenmontage-Kontaktelement und der Leiterbahn in besonders einfacher Weise einzuhalten. Anders als bei herkömmlichen Oberflächenmontage-Kontaktelementen, die mit besonders engen Toleranzen gefertigt werden müssen, um nach dem Aufsetzen des Steckverbinders auf die Leiterplatte den erforderlichen Abstand von etwa 0,1 mm zwischen Kontaktelement und Leiterbahn zu erhalten, stellt sich bei dieser Ausführungsform der erforderliche Abstand durch entsprechend weite Verschiebung des Anschlußelementes auf dem Anschlußbereich von selbst ein.According to a preferred embodiment of the invention it is provided that the surface-mounted contact element is provided with a connection region on which a connection element is arranged, which is displaceable relative to the connection region. This design makes it possible to comply with the critical in the surface mounting technology thickness of the solder pad between the surface-mount contact element and the conductor in a particularly simple manner. Unlike conventional surface mount contact elements, which must be made with very tight tolerances to get after placing the connector on the circuit board the required distance of about 0.1 mm between the contact element and conductor, arises in this embodiment the required distance by a correspondingly wide displacement of the connection element on the connection area by itself.

In Figur 1 ist ein Steckverbinder gezeigt. Es handelt sich hier um eine abgewinkelte Federleiste, da die einzelnen Kontakte um jeweils 90° abgewinkelt sind und auf der Anschlußseite des Steckverbinders als Kontaktfedern ausgebildet sind. Der komplementäre Steckverbinder, der in den gezeigten Steckverbinder eingesteckt wird, ist dementsprechend eine Messerleiste. Die gezeigte Ausführungsform kann natürlich auch als Messerleiste ausgebildet sein. In jedem Fall weist der Steckverbinder eine Vielzahl von Kontakten auf, die in mehreren nebeneinanderliegenden Spalten angeordnet sind. In der Schnittdarstellung von Figur 1 ist nur eine einzige dieser Spalten zu sehen.In Figure 1, a connector is shown. This is an angled spring bar, since the individual contacts are angled at 90 ° and are formed on the connection side of the connector as a contact springs. The complementary connector, which is inserted into the connector shown, is accordingly a male connector. Of course, the embodiment shown can also be designed as a male connector. In any case, the connector has a plurality of contacts, which in several adjacent columns are arranged. In the sectional view of Figure 1, only a single one of these columns can be seen.
Der gezeigte Steckverbinder weist einen isolierenden Trägerkörper 10 auf, in welchem zweimal zwei Oberflächenmontage-Kontaktelemente 20 angeordnet sind sowie ein Durchsteckmontage-Kontaktelement 38, das die beiden Gruppen von Oberflächenmontage-Kontaktelementen 20 voneinander trennt. Das Durchsteckmontage-Kontaktelement 38 kann mit einem Masseleiter verbunden werden und dient als Abschirmung zwischen den beiden Gruppen von Oberflächenmontage-Kontaktelementen 20, die zur Signalübertragung dienen.The connector shown has an insulating support body 10 in which two surface-mount contact elements 20 are arranged twice and a through-mount contact element 38 which separates the two sets of surface-mount contact elements 20 from each other. The through-mounting contact element 38 may be connected to a ground conductor and serves as a shield between the two groups of surface-mount contact elements 20 which serve to transmit signals.
Der Steckverbinder wird bei der Montage mit seinem Durchsteckmontage-Kontaktelement in eine Öffnung 50 einer Leiterplatte 52 eingesetzt, auf die vorher an den entsprechenden Stellen eine Lötpaste aufgebracht wurde. In diesem Zustand ist der Steckverbinder vorfixiert. Anschließend erfolgt die Verlötung der Kontaktelemente, so daß die gewünschte elektrische Verbindung mit den Leiterbahnen erzielt ist.The connector is used in the assembly with its through-hole contact element in an opening 50 of a printed circuit board 52, on the previously in the appropriate places a solder paste was applied. In this state, the connector is pre-fixed. Subsequently, the soldering of the contact elements, so that the desired electrical connection with the conductor tracks is achieved.
In Figur 2 ist ein Steckverbinder gemäß einer ersten Ausführungsform der Erfindung gezeigt. Bei dieser Ausführungsform werden drei Kontaktelemente verwendet, nämlich ein innenliegendes Durchsteckmontage-Kontaktelement 38, das in eine Öffnung 50 einer Leiterplatte 52 eingreift, ein mittig liegendes Oberflächenmontage-Kontaktelement 20, das mit einem Anschlußbereich 22 versehen ist, auf dem ein Anschlußelement 24 angeordnet ist; und ein außenliegendes Oberflächenmontage-Kontaktelement 53, das an seinem der Leiterplatte zugewandten Ende mit einer Umbiegung versehen ist, die auf der Leiterplatte aufliegt und dort in einer Oberflächenmontagetechnik mit einer entsprechenden Leiterbahn verbunden werden kann.FIG. 2 shows a plug connector according to a first embodiment of the invention. In this embodiment, three contact elements are used, namely an internal through-hole contact element 38 which engages an opening 50 of a printed circuit board 52, a central surface mount contact element 20 provided with a terminal region 22 on which a terminal 24 is disposed; and an outboard surface mount contact member 53 provided with a bend at its end facing the circuit board, which rests on the circuit board where it can be connected to a corresponding trace in a surface mount technique.
In Figur 3 ist das Anschlußelement 24 gezeigt, das bei den Oberflächenmontage-Kontaktelementen 20 des in Figur 2 gezeigten Steckverbinders verwendet wird. Das Anschlußelement 24 ist als federnde Klammer mit zwei Schenkeln 26 ausgebildet, die mittels eines Bodens 28 miteinander verbunden sind. Am Boden ist auf der vom Anschlußbereich 22 abgewandten Seite ein Abstandshalter 30 vorgesehen, der als Prägung so ausgebildet ist, daß ein vergleichsweise spitzer Scheitel entsteht.FIG. 3 shows the connection element 24 that is used in the surface-mount contact elements 20 of the connector shown in FIG is used. The connecting element 24 is designed as a resilient clamp with two legs 26 which are connected to each other by means of a bottom 28. At the bottom, a spacer 30 is provided on the side facing away from the terminal portion 22, which is formed as an embossing so that a comparatively sharp vertex is formed.
Das Anschlußelement 24 ist auf den Anschlußbereich 22 des Oberflächenmontage-Kontaktelementes 20 aufgeschoben und an diesem durch die aus der wirkenden Klemmkraft resultierende Reibungskraft fixiert. Um zu verhindern, daß das Anschlußelement von dem Anschlußbereich 22, der einen rechteckigen Querschnitt hat, abrutscht, sind an einem der Schenkel 26 des Anschlußelementes 24 abgebogene Nasen 54 vorgesehen, deren einander gegenüberliegende Flächen als Führungsflächen 56 wirken. Diese können an den schmalen Außenflächen der Anschlußbereiche 22 angreifen und verhindern, daß das Anschlußelement 24 übermäßig stark abkippt oder gar abrutscht.The connecting element 24 is pushed onto the connecting region 22 of the surface-mounted contact element 20 and fixed thereto by the frictional force resulting from the acting clamping force. In order to prevent the connecting element from slipping off the connecting region 22, which has a rectangular cross-section, bent lugs 54 are provided on one of the legs 26 of the connecting element 24, whose opposing surfaces act as guide surfaces 56. These can attack on the narrow outer surfaces of the terminal portions 22 and prevent the terminal member 24 tilts excessively or even slip off.
Anhand von Figur 4 wird nun die Montage einer weiteren Ausführungsform eines Steckverbinders an einer Leiterplatte beschrieben. Es handelt sich bei dieser Ausführungsform um eine gerade Federleiste, wobei in einer einzigen Reihe hintereinanderliegend Oberflächenmontage-Kontaktelemente und Durchsteckmontage-Kontaktelemente vorgesehen sind.The assembly of a further embodiment of a connector on a printed circuit board will now be described with reference to FIG. It is in this embodiment, a straight spring bar, wherein in a single row, one behind the other surface-mounted contact elements and through-hole contact elements are provided.
Zunächst wird die Leiterplatte an den Stellen, die zur Verbindung mit den Kontaktelementen vorgesehen sind, mit einer Lötpaste beschichtet. Anschließend wird der Steckverbinder auf die Leiterplatte aufgesetzt, wobei das Durchsteckmontage-Kontaktelement in die entsprechende Öffnung der Leiterplatte eindringt. Dabei ist die in Figur 4a gezeigte Montagestellung der Kontaktelemente 24 so gewählt, daß der Abstandshalter 30 an der Leiterplatte anliegt, bevor das Durchsteckmontage-Kontaktelement 38 vollständig in die Leiterplatte eingeschoben ist. Im Verlauf des Aufsetzens des Steckverbinders auf die Leiterplatte taucht das Anschlußelement 24 in die dort vorher aufgebrachte Lötpaste ein, wobei der Abstandshalter 30 mit seinem Scheitel die Lötpaste zuverlässig verdrängt und durchdringt, so daß er auf der Leiterplatte aufliegt. Dies gewährleistet, daß der Boden 28 in allen übrigen Bereichen einen vorbestimmten, von der Höhe des Abstandshalters vorgegebenen Abstand von der Leiterplatte aufweist, der vorzugsweise 0,1 mm beträgt und vollständig mit der Lötpaste gefüllt ist. Im Verlauf des Aufsetzens ergibt sich auch eine Relativverschiebung zwischen dem Anschlußelement 24 und dem Anschlußbereich 22, wodurch die Schenkel 26 des als Klammer ausgebildeten Anschlußelementes weiter auf den Anschlußbereich 22 aufgeschoben werden. Dieser Zustand, in welchem die elektrische Verbindung zwischen dem Anschlußelement 24 und dem Anschlußbereich 22 sowie der optimale Abstand zwischen dem Boden des Anschlußelementes und der Leiterbahn unabhängig von den jeweils vorliegenden Toleranzen gewährleistet ist, ist in Figur 4b gezeigt.First, the circuit board is coated with a solder paste at the locations provided for connection to the contact elements. Subsequently, the connector is placed on the circuit board, wherein the through-hole contact element penetrates into the corresponding opening of the circuit board. In this case, the assembly position of the contact elements 24 shown in Figure 4a is selected so that the spacer 30 abuts the circuit board before the through-hole contact element 38 is fully inserted into the circuit board. In the course of placement of the connector on the circuit board, the connecting element 24 immersed in the there previously applied solder paste, wherein the spacer 30 reliably displaces the solder paste with its apex and penetrates, so that it rests on the circuit board. This ensures that the bottom 28 in all other areas has a predetermined, predetermined by the height of the spacer distance from the circuit board, which is preferably 0.1 mm and is completely filled with the solder paste. In the course of placement also results in a relative displacement between the connecting element 24 and the terminal portion 22, whereby the legs 26 of the terminal formed as a clamp element are further pushed onto the connection portion 22. This state, in which the electrical connection between the connection element 24 and the connection region 22 and the optimum distance between the bottom of the connection element and the conductor path is ensured independently of the respectively existing tolerances, is shown in FIG. 4b.
Sobald der Steckverbinder korrekt auf die Leiterplatte aufgesetzt ist, kann die Verlötung der Oberflächenmontage-Kontaktelemente erfolgen, wobei aufgrund des präzise eingehaltenen Abstandes zwischen dem Boden des Anschlußelementes 24 und der Leiterplatte eine zuverlässige Verlötung gewährleistet ist. Dieser Abstand zwischen dem Boden 28 des Anschlußelementes 24 und der Leiterplatte wird nicht beeinflußt von Toleranzen des Steckverbinders oder von Oberflächenunebenheiten der Leiterplatte, da eventuelle Toleranzen durch ein unterschiedlich weites Aufschieben des Anschlußelementes auf den Anschlußbereich 22 des Oberflächenmontage-Kontaktelementes ausgeglichen werden.Once the connector is correctly placed on the circuit board, the soldering of the surface-mounted contact elements can be done, which is guaranteed due to the precisely maintained distance between the bottom of the connecting element 24 and the circuit board reliable soldering. This distance between the bottom 28 of the connecting element 24 and the circuit board is not affected by tolerances of the connector or surface irregularities of the circuit board, as any tolerances are compensated by a different wide sliding of the connecting element to the terminal portion 22 of the surface-mount contact element.
