Description

Die Erfindung betrifft einen Leiterkartensteckverbinder zur Montage auf parallel angeordneten Leiterkarten, wobei mindestens zwei als koaxiales Kontaktpaar ausgebildete Steckmodule vorgesehen sind, von denen in dem einen ein Stiftkontakt und in dem anderen ein Buchsenkontakt eingebracht ist, wobei der Stift- oder Buchsenkontakt zentral in einem Isolationselement gehalten ist, dass von einem elektrisch leitenden Hülsenkontakt umgeben ist.The invention relates to a printed circuit board connector for mounting on parallel printed circuit boards, wherein at least two designed as a coaxial contact pair plug-in modules are provided, one of which in the one pin contact and in the other a socket contact is introduced, wherein the pin or socket contact held centrally in an insulating element is that is surrounded by an electrically conductive sleeve contact.

Eine derartige Vorrichtung wird benötigt, um zwei zumindest annähernd parallel zueinander angeordnete Leiterkarten miteinander zu kontaktieren, wobei durch die Ausgestaltung der Kontaktelemente auch eine Schiefstellung oder ein Positionsversatz der Steckmodule sowie der Leiterkarten zueinander in gewissen Grenzen überbrückbar ist.Such a device is required in order to contact two printed circuit boards arranged at least approximately parallel to one another, wherein due to the configuration of the contact elements, a skewing or positional offset of the plug-in modules and the printed circuit boards can be bridged to one another within certain limits.

Stand der TechnikState of the art

Aus der EP1 246 304 B1 ist ein Koaxial-Steckerteil bekannt, bei dem ein mit einem Kugelkopf ausgebildeter Mittelkontakt um einen bestimmten Winkel innerhalb eines U-förmigen Federkontaktes drehbar kontaktiert ist. Weiterhin ist aus der US 5,980,290 ein elektrischer Koaxialsteckverbinder mit einem beweglichen Kontakt bekannt, bei dem jedoch nur einer der beiden Steckteile beweglich angeordnet ist.From the EP1 246 304 B1 is a coaxial connector part is known in which a trained with a ball head center contact is rotatably contacted by a certain angle within a U-shaped spring contact. Furthermore, from the US 5,980,290 an electrical coaxial connector with a movable contact known in which, however, only one of the two plug-in parts is arranged to be movable.

Die US 6,497,579 B1 zeigt einen Leiterplattenkoaxialverbindung mit einem im wesentlichen zylindrischen Adapter, der mit einem ersten Ende mit einem ersten Verbinderelement und mit einem zweiten Ende mit einem zweiten Verbinderelement elektrisch verbunden ist, wobei das erste Verbinderelement auf einer Leiterplatte befestigt ist.The US Pat. No. 6,497,579 B1 shows a printed circuit board coaxial connection with a substantially cylindrical adapter having a first end with a first connector element and with a second end with a second Connector element is electrically connected, wherein the first connector element is mounted on a printed circuit board.

Derartige, bekannte koaxiale Steckverbindungen zur direkten Kontaktierung von zwei Leiterplatten, nutzen in der Regel zwei identische und starre Kontaktmodule oder auch tonnenförmige Distanzelemente, und sind daher nur taktmodule oder auch tonnenförmige Distanzelemente, und sind daher nur bedingt in der Lage, eine Verschiebung bzw. eine Schiefstellung einzelner Module auszugleichen.Such known coaxial connectors for direct contacting of two circuit boards, usually use two identical and rigid contact modules or barrel-shaped spacers, and are therefore only Clock modules or barrel-shaped spacers, and are therefore only partially able to compensate for a shift or a misalignment of individual modules.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art dahingehend auszubilden, dass zum einen sicherzustellen ist, die koaxialen Steckmodule selbstfangend auszubilden, um gewisse Positionsungenauigkeiten zwischen zwei Leiterkarten auszugleichen und zum anderen, dass auch leicht unterschiedliche Abstände zwischen den Leiterkarten einfach und ohne besonderes Distanzelement zu überbrücken sind.The invention is therefore the object of a device of the type mentioned in such a way that on the one hand to form the coaxial plug-in modules self-catching to compensate for certain positional inaccuracies between two circuit boards and on the other hand, that also slightly different distances between the circuit boards easy and are bridged without special spacer.

Diese Aufgabe wird dadurch gelöst, dass in den Steckmodulen jeweils ein Kontakthalter mit einer zentralen Öffnung angeordnet ist, innerhalb derer, beabstandet vom Kontakthalter, ein Kontaktelement mit einer kugelförmigen Ausbildung fixiert ist,
dass der Stift- oder Buchsenkontakt in einer Innenbohrung eine kugelförmige Ausnehmung aufweist, die mit der kugelförmigen Ausbildung des Kontaktelementes elektrisch kontaktiert,
dass der elektrisch leitende Hülsenkontakt eine Schlitzbuchse mit einem konkav geformten Kontaktbereich aufweist, der einen in der zentralen Öffnung des Kontakthalters eingeformten balligen Ring kontaktiert, und dass der Hülsenkontakt zusammen mit dem Stift- oder Buchsenkontakt mittels der kugelförmigen Ausbildung des Kontaktelementes um einen bestimmten axialen Bereich dreh- und schwenkbar ist.This object is achieved in that in the plug-in modules each have a contact holder is arranged with a central opening, within which, spaced from the contact holder, a contact element is fixed with a spherical configuration,
in that the pin or socket contact in an inner bore has a spherical recess which makes electrical contact with the spherical formation of the contact element,
in that the electrically conductive sleeve contact has a slot bushing with a concave shaped contact area which contacts a spherical ring formed in the central opening of the contact holder, and that the sleeve contact rotates together with the pin or socket contact by means of the spherical configuration of the contact element around a certain axial area - and is pivotable.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 9 angegeben.Advantageous embodiments of the invention are specified in claims 2-9.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass hier ein äußerst einfach aufgebautes, als Stift- oder Buchsenkontakt ausgebildetes koaxiales Steckmodul als Leiterkartensteckverbinder gezeigt wird, wobei die Kontakte mittels eines Kugelgelenkes, ein Verschwenken um einen bestimmten Betrag erlauben, der jedoch abhänging vom Leiterkartenabstand ist und bei einem Abstand der Karten von 6 mm etwa +/- 5° beträgt. Damit können auch Fehlpositionierungen der Steckmodule auf den beiden Leiterkarten von etwa 0,5 mm ausgeglichen werden.
Wobei anzumerken ist, dass jeder der beiden Steckmodule um seine Steckachse dreh- und schwenkbar ist.
Für ein einfaches "Einfangen" des jeweiligen Gegensteckmodules weist das mit dem Stiftkontakt ausgerüstete Steckmodul vorteilhaft einen Hülsenkontakt mit einer glockenförmigen Öffnung auf, in die der Buchsenkontakt mit einem zur Kontaktierung umlaufenden, balligen Vorsprung auf seinem steckseitigen Hülsenkontakt einfügbar ist.
Weiterhin ist vorteilhaft, dass ohne weitere Maßnahmen und für den zuvor skizzierten Fall, Höhenunterschiede von etwa 1,2 mm zwischen den Steckmodulen ausgleichbar sind.
Darüber hinaus gewünschte, zu überbrückende Abstände zwischen den Leiterkarten werden durch eine Verlängerung des stiftseitigen Steckmoduls erzielt, so dass keine zusätzlichen Adapter zur Überbrückung benötigt werden. Hervorzuheben sind auch die extrem kleinen Abmessungen, die lediglich eine Fläche von 5x5 mm je Steckmodul beanspruchen.
Zwar werden relativ teure Drehteile benötigt, jedoch kann dies durch eine Anzahl gleicher Bauteile im Stift- bzw. Buchsenkontakt egalisiert werden. Weiterhin besteht die Möglichkeit, eine derartige Steckkombination durch eine Anordnung mehrerer Einzelkontakte für den Aufbau eines Multikontaktsteckers zu nutzenThe advantages achieved by the invention are in particular that here a very simple design, designed as a pin or socket contact coaxial plug-in module is shown as a printed circuit board connector, wherein the contacts by means of a ball joint, a pivoting allow by a certain amount, but which is dependent on the conductor card spacing and at a distance of the cards of 6 mm is about +/- 5 °. This can also compensate for incorrect positioning of the plug-in modules on the two printed circuit boards of about 0.5 mm.
It should be noted that each of the two plug-in modules is rotatable and pivotable about its thru-axle.
For a simple "capture" of the respective mating plug module equipped with the pin contact plug-in advantageously has a sleeve contact with a bell-shaped opening, in which the socket contact with a circumferential contact, spherical projection on its plug-side sleeve contact can be inserted.
Furthermore, it is advantageous that without further measures and for the previously outlined case, height differences of about 1.2 mm between the plug-in modules are compensated.
In addition, desired distances to be bridged between the printed circuit boards are achieved by an extension of the pin-side plug-in module, so that no additional adapter is required for bridging. Particularly noteworthy are the extremely small dimensions, which require only an area of 5x5 mm per plug-in module.
Although relatively expensive turned parts are needed, but this can be equalized by a number of identical components in the pin or socket contact. Furthermore, it is possible to use such a plug-in combination by arranging a plurality of individual contacts for the construction of a multi-contact plug

Die Steckbereiche von Stift 11 und Buchse 21 enden jeweils an einem Absatz 12, 22 an den sich ein geschlitztes Hülsenteil 13, 23 mit mehreren radialen Vorsprüngen 14, 24 anschließt.
Innerhalb des Hülsenteiles 13, 23 ist eine axiale Bohrung 15, 25 mit einer kugelförmigen Ausnehmung 16, 26 vorgesehen, in die bei der Montage später eine kugelförmige Ausbildung 41 eines Kontaktelementes 40 eingreift.The Fig. 1a, 1b shows a designed as a pin and a socket contact inner contact of a coaxial plug-in module, which are designed almost identical.
The only difference is that the mating side of the female contact 20 has a pin-shaped but slotted socket 21, while the pin contact 10 has a closed pin 11.
The plug-in areas of pin 11 and socket 21 each terminate at a shoulder 12, 22 to which a slotted sleeve part 13, 23 with a plurality of radial projections 14, 24 connects.

It is in the Fig. 2a the pin contact associated with the sleeve contact 30 and shown in the Fig. 2b the socket contact associated sleeve contact 30 '.

Die beiden hülsenförmigen Körper weisen jeweils eine identische Schlitzbuchse 31 auf, mit der sie in einem Kontakthalter 45 dreh- und schwenkbar gehalten sind, sowie einen Steckbereich 32 zu Kontaktierung mit dem jeweiligen Gegenstecker.
Dabei weist der Hülsenkontakt 30 eine trichterförmige Kontaktöffnung 35 auf, während der Hülsenkontakt 30' einen als Schlitzhülse 33 ausgebildeten Steckbereich mit hier vier Schlitzen 34 zeigt, mit einem außen umlaufenden, ringförmigen Vorsprung 36 für eine gute Kontaktierung in der trichterförmigen Kontaktöffnung 35 des Hülsenkontaktes 30.
Im Inneren der Schlitzbuchse 31 der beiden Hülsenkontakte 30, 30' ist je ein konvexer Ring 37 vorgesehen, der in eine konkave Außenrille 52 eines Isolationselementes 50 eingreift, mittels dem auch der innere Stiftkontakt 10 oder der Buchsenkontakt 20 innerhalb des außenliegenden Hülsenkontaktes 30, 30' fixiert ist.
Die Schlitzbuchse 31 weist einen konkav ausgebildeten äußeren Kontaktbereich 38 auf, der eine gewisse Schwenkbewegung innerhalb des Kontakthalters 45 zulässt, der dazu eine Öffnung 47 mit einem balligen Ring 48 aufweist.The two sleeve-shaped body each have an identical slot bushing 31, with which they are rotatably and pivotally held in a contact holder 45, and a plug-in area 32 for contacting with the respective mating connector.
In this case, the sleeve contact 30 has a funnel-shaped contact opening 35, while the sleeve contact 30 'designed as a slot sleeve 33 plug region with four slots 34 here, with an outer circumferential, annular projection 36 for a good contact in the funnel-shaped contact opening 35 of the sleeve contact 30th
In the interior of the slot bushing 31 of the two sleeve contacts 30, 30 'is each a convex ring 37 is provided which engages in a concave outer groove 52 of an insulating member 50, by means of which the inner pin contact 10 or the female contact 20 within the outer sleeve contact 30, 30' is fixed.
The slot bushing 31 has a concave outer contact region 38, which allows a certain pivoting movement within the contact holder 45, which has an opening 47 with a crowned ring 48 for this purpose.

Die Fig. 3 zeigt das Isolationselement 50 aus einem isolierenden Werkstoff, das kreisförmig, mit einer zentralen Öffnung 51 ausgebildet ist. In der Wandung ist eine konkav ausgebildete Außenrille 52 vorgesehen.

Während auf der entgegengesetzten Seite zur kugelartigen Anformung 41 der Fuß 42 eine kegelförmige Spitze 43 zum Auflöten auf der Leiterkarte 5 aufweist.While on the opposite side to the ball-like Anformung 41, the foot 42 has a conical tip 43 for soldering on the circuit board 5.

Das Kontaktelement 40 ist bei der Montage der Steckmodule mittig innerhalb der Öffnung 47 des Kontakthalters 45, aber von diesem beabstandet angeordnet, wie in der Fig. 6 gezeigt ist.The contact element 40 is in the assembly of the plug modules centrally within the opening 47 of the contact holder 45, but spaced therefrom, as in the Fig. 6 is shown.

Der Kontakthalter 45 in Fig. 5a ist hier als flaches, quadratisches Element ausgebildet, an dessen Eckseiten Positionierungsstifte 46 angeformt sind, mittels derer primär die Haltekräfte des Steckmoduls auf die Leiterkarte übertragen werden. Während ein umlaufender Ring (hier zwischen den Positionierungsstiften) - eine Lötkante 49 - eine abschirmende Wirkung des Kontakthalters 45 für das Kontaktelement 40 bewirkt.
Der Kontakthalter 45 weist in seiner zentralen Öffnung 47 einen innen umlaufenden, balligen Ring 48 auf, der zur Kontaktierung mit dem innenliegenden konkaven Kontaktbereich 38 des Hülsenkontaktes 30, 30' dient.The contact holder 45 in Fig. 5a is designed here as a flat, square element, on whose corner sides positioning pins 46 are formed, by means of which primarily the holding forces of the plug-in module are transmitted to the printed circuit board.

In der Fig. 5b ist in einem mittigen Schnitt eine Variante des Kontakthalters 45 gezeigt, die einen oberflächenlötbaren Kontakthalter 45' zeigt, der ohne Positionierungsstifte direkt mittels der Lötkanten 49 auf einer Leiterkarte 5 auflötbar ist, und dessen Innenbereich einen konkaven Ring 48' aufweist.In the Fig. 5b a variant of the contact holder 45 is shown in a central section, which shows a surface-solderable contact holder 45 ', which can be soldered without positioning pins directly by means of Lötkanten 49 on a printed circuit board 5, and the inner region has a concave ring 48'.

Die Fig. 6a zeigt einen zusammengefügten Leiterkartensteckverbinder in einer teilweise geschnittenen Darstellung.
Dazu ist ein Steckmodul 3 gezeigt, mit einem Stiftkontakt 10, fixiert in dem Isolationselement 50, das Kontaktelement 40 kontaktierend, und umgeben von dem Hülsenkontakt 30 und beweglich gehalten in dem Kontakthalter 45.The Fig. 6a shows an assembled printed circuit board connector in a partially sectioned view.
For this purpose, a plug-in module 3 is shown, with a pin contact 10, fixed in the insulation element 50, the contact element 40 contacting, and surrounded by the sleeve contact 30 and movably held in the contact holder 45th

Dabei ist erkennbar, dass ein Verschwenken des Hülsenkontaktes 30 primär über die kugelförmige Ausnehmung 16 des Stiftkontaktes 10 und die kugelförmige Ausbildung 41 des auf einer Leiterkarte zu fixierenden Kontaktelementes 40 erfolgt.It can be seen that pivoting of the sleeve contact 30 takes place primarily via the spherical recess 16 of the pin contact 10 and the spherical formation 41 of the contact element 40 to be fixed on a printed circuit board.

Wobei gleichzeitig die Bewegung mittels des konkaven Kontaktbereiches 38 der Schlitzbuchse 31 innerhalb des balligen Innenringes 48 des Kontakthalters 45 ausführt wird.Wherein at the same time the movement is carried out by means of the concave contact portion 38 of the slot bushing 31 within the crowned inner ring 48 of the contact holder 45.

Die Variante dazu ist in der Detaildarstellung der Fig. 6b gezeigt.
Hier sind die bereits in der Fig. 5b angedeuteten baulichen Änderungen der Außenkontaktierung zwischen dem Kontakthalter 45' und der Schlitzbuchse 31' des Hülsenkontaktes 30, 30' dargestellt. Dabei ist der Kontaktbereich 38' konvex, also tonnenförmig ausgebildet und wird damit in dem konkaven Ring 48' des Kontakthalters 45' beweglich gehalten.
Wobei dieser Kontakthalter wahlweise auch Positionierungsstifte aufweisen kann.The variant is in the detailed representation of Fig. 6b shown.
Here are already in the Fig. 5b indicated structural changes in the external contact between the contact holder 45 'and the slot bush 31' of the sleeve contact 30, 30 'shown. In this case, the contact region 38 'convex, so barrel-shaped and is thus held in the concave ring 48' of the contact holder 45 'movable.
Where this contact holder can optionally also have positioning pins.

Die Fig. 7a und 7b zeigen jeweils ein montiertes Steckmodul 3 und 3' mit dem Kontakthalter 45 und seinen Positionierungsstiften 46, den Hülsenkontakten 30, 30' und den zugehörigen Stift- und Buchsenkontakten 10, 20.The Fig. 7a and 7b each show a mounted plug-in module 3 and 3 'with the contact holder 45 and its positioning pins 46, the sleeve contacts 30, 30' and the associated pin and socket contacts 10, 20th

In der Fig. 8 sind zwei zu steckende Steckmodule 3, 3' montiert, jeweils auf einer Leiterkarte 5 mit einem leichten seitlichen Versatz gezeigt, innerhalb dessen noch ein "Fangen" zwischen dem Trichter 35 des Hülsenkontaktes 30 und dem Steckbereich 32 des Hülsenkontaktes 30' durchführbar ist.In the Fig. 8 two plug-in modules 3, 3 'are mounted, each shown on a printed circuit board 5 with a slight lateral offset within which still a "catching" between the funnel 35 of the sleeve contact 30 and the plug-in portion 32 of the sleeve contact 30' is feasible.
