Abstract

The coaxial connector provides a reciprocal connection of current (conductor) paths running in parallel planes, on spaced apart circuit boards. A first insulator (2) is associated with the first circuit board. A central signal line (6) passes through the first insulator. The latter has a shield contact (3) on its outer side. The signal line (6) and the shield contact (3) can be connected to the current tracks of the first circuit board (1). A second insulator (2') is associated with the second circuit board (1'). A central signal line passes through this and it has an outer shield contact. The signal line and the contact are connected to the current tracks of the second circuit board. The signal lines or contacts are electrically connected together by coupling the two circuit boards together. Each insulator of each circuit board which determine the relative position of the signal lines relative to the contact, define, with the respective circuit board, the distance of a contact surface from the circuit board, using a spacer member. The latter has a shield contact of appropriate dimensions. The first and second circuit boards can be coupled together by the outgoing signal lines or shield contacts of the first and second insulators and via the spacer member signal line or contact.

Description

Die Erfindung bezieht sich auf einen Koax-Verbinder nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a coax connector according to the preamble of claim 1.

Bei bekannten Ausführungen dieser Art bedarf es bei Beibehaltung gleichbemessener erster Isolierkörper der ersten Leiterplatten zur Überbrückung unterschiedlich großer Abstände der Leiterplatten voneinander unterschiedlich langer Signalstiftteile und Abschirmkontakte der zweiten Isolierkörper.In known designs of this type, the same first insulating bodies of the first printed circuit boards are required to bridge different distances between the printed circuit boards and signal pin parts of different lengths and shielding contacts of the second insulating bodies.

Dies hat sich wegen der Notwendigkeit einer entsprechend aufwendigen Lagerhaltung sowie der Montage unmittelbar vor dem Einsatz als außerordentlich umständlich und kostspielig herausgestellt.This has been due to the need for a correspondingly complex storage and assembly immediately before Use shown to be extremely cumbersome and costly.

Der Erfindung liegt die Aufgabe zugrunde, den Koax-Verbinder der eingangs genannten Art unter erheblicher Vereinfachung so weiter auszubilden, daß es der Bereitstellung von unterschiedlichen bemessenen zweiten Isolierkörpern zwecks Berücksichtigung unterschiedlicher Abstände der Leiterplatten voneinander nicht mehr bedarf.The invention has for its object to further develop the coax connector of the type mentioned with considerable simplification so that it is no longer necessary to provide different sized second insulating bodies in order to take into account different distances between the circuit boards.

Diese Aufgabe wird erfindungsgemäß im wesentlichen durch die im kennzeichnenden Teil des Patentanspruchs 1 herausgestellten Merkmale gelöstThis object is achieved essentially by the features highlighted in the characterizing part of patent claim 1

Aufgrund dieser Ausbildung der Koax-Verbinder ist es nunmehr möglich, ihre Isolierkörper-Abschirmkontakt-Signalleiter-Einheiten mit den zugehörigen Leiterplatten zu festen Einheiten vorzufertigen und diese Einheiten dem jeweiligen Bedarfsfall entsprechend in Abhängigkeit von ihrem vorgesehenen gegenseitigen Abstand über auf diesen Abstand abgestimmte Distanzstücke zu verbinden. Dabei hat es sich als besonders vorteilhaft erwiesen, wenn die Kontaktflächen jeweils durch eine der beiden Stirnflächen der Isolierkörper gebildet sind.Due to this design of the coax connector, it is now possible to prefabricate their insulator shield contact signal conductor units with the associated printed circuit boards to form fixed units and to connect these units according to the respective need, depending on their intended mutual spacing, using spacers matched to this spacing . It has proven to be particularly advantageous if the contact surfaces are each formed by one of the two end surfaces of the insulating body.

Eine besonders rationelle Fertigung ergibt sich, wenn die Distanzstücke jeweils als Drehteile ausgeführt sind. Aufgrund dessen ist auch eine preisgünstige Fertigung kleiner Stückzahlen an Distanzstücken unterschiedlicher Länge möglich.A particularly efficient production results if the spacers are each designed as turned parts. Because of this, low-cost production of small numbers of spacers of different lengths is also possible.

Demgegenüber lassen sich die ersten und zweiten Isolierkörper wegen der nunmehr möglichen einheitlichen Ausbildung und Dimensionierung mit einem erst bei größeren Stückzahlen rationell als Stanz-Biege-Teil herstellbaren Abschirmkontakt ausrüsten. Dies bietet in weiterer zweckmäßiger Ausgestaltung die vorteilhafte Möglichkeit, die Abschirmkontakte im gleichen Herstellungsschritt als SMT-Buchsen mit gestanzten Lötzungen zu versehen.In contrast, because of the now possible uniform design and dimensioning, the first and second insulating bodies can be equipped with a shielding contact which can only be produced rationally as a stamped and bent part in larger quantities. In a further expedient embodiment, this offers the advantageous possibility of providing the shielding contacts with stamped solder tongues in the same manufacturing step as SMT sockets.

Aus der Zeichnung ergibt sich, daß auf der unteren Leiterplatte 1 zwei zylindrische Isolierkörper 2 mit jeweils einem an ihrer Außenseite vorgesehenen Abschirmkontakt 3 in Form einer Kontaktblech-Buchse über als SMT-Anschluß dienende Lötzungen 4 festgelegt sind, und zwar auf ihnen zugeordneten, nicht näher dargestellten Leiterbahnen der Leiterplatte 1. Jeder Isolierkörper 2 weist eine mittige, im Querschnitt rechteckige Öffnung 5 auf. Durch diese erstreckt sich ein zentraler Signalleiter 6, der, wie aus der Zeichnung ersichtlich, als Klemmkontakt ausgeführt und mit einer eigenen Lötzunge 7 (Fig. 4 und 5) versehen ist. An der Innenwand des Abschirmkontaktes 3 liegt ein sich auf der Stirnfläche des Isolierkörpers 2 abstützender Kontaktring 8 mit einer Abstufung 9 an, der über die Außenkante des Abschirmkontaktes 3 vorsteht und so dessen Verlängerung bildet.From the drawing it follows that on the lower circuit board 1, two cylindrical insulating bodies 2, each with a shielding contact 3 provided on the outside thereof in the form of a contact plate socket, are defined by soldering tongues 4 serving as SMT connection, specifically not assigned to them illustrated conductor tracks of the circuit board 1. Each insulating body 2 has a central opening 5 with a rectangular cross section. A central signal conductor 6 extends through this, which, as can be seen from the drawing, is designed as a clamping contact and is provided with its own soldering tongue 7 (FIGS. 4 and 5). On the inner wall of the shielding contact 3 there is a contact ring 8, which is supported on the end face of the insulating body 2 and has a gradation 9, which projects beyond the outer edge of the shielding contact 3 and thus forms its extension.

Auf der rechten oberen Leiterplatte 1' die in einem Abstand a von der unteren Leiterplatte 1 angeordnet ist, und auf der in einem kleineren Abstand zur unteren Leiterplatte 1 angeordneten linken Leiterplatte 1'' ist analog jeweils ein Isolierkörper 2' mit Abschirmkontakt 3' mittels Lötzungen 4' festgelegt. Auch dieser Isolierkörper 2' besitzt eine rechteckige Öffnung 5' zur Aufnahme eines zentralen Signalleiters 6', der in einen Klemmkontakt ausläuft. Dieser Signalleiter 6' ist analog mit einer Lötzunge 7' versehen. Der Abschirmkontakt 3' ist über einen Kontaktring 8' mit einer Abstufung 9' auf gleiche Weise verlängert.On the upper right printed circuit board 1 ', which is arranged at a distance a from the lower printed circuit board 1, and on the left printed circuit board 1' ', which is arranged at a smaller distance from the lower printed circuit board 1, there is analogously an insulating body 2' with shielding contact 3 'by means of soldering tongues 4 'set. This insulating body 2 'also has a rectangular opening 5' for receiving a central signal conductor 6 'which ends in a terminal contact. This signal conductor 6 'is analogously provided with a soldering tongue 7'. The shielding contact 3 'is extended in the same way via a contact ring 8' with a gradation 9 '.

Die elektrische Verbindung zwischen den Leiterplatten 1 und 1' bzw. 1'' mit den an ihnen festgelegten Abschirmkontakt-Kontaktring-Isolierkörper-Signalleiter-Einheiten 3, 8, 2, 6; 3', 8', 2', 6' ist über jeweils ein zylindrisches Distanzstück 10 bzw. 1O'' sichergestellt, das in einer zentralen Durchgangsbohrung 11 von einem in Isolierstoff 12 eingebetteten Signalkontaktstift 13 durchsetzt ist. Sowohl die Wandung der Durchgangsbohrung 11 als auch die Außenfläche des Signalkontaktstifts 13 sind mit den festen Halt des Signalstifts 13 in der Durchgangsbohrung 11 sicherstellenden Abstufungen versehen.The electrical connection between the circuit boards 1 and 1 'or 1' 'with the shield contact contact ring insulator-signal conductor units 3, 8, 2, 6; 3 ', 8', 2 ', 6' is ensured in each case by a cylindrical spacer 10 or 10 '' which is penetrated in a central through hole 11 by a signal contact pin 13 embedded in insulating material 12. Both the wall of the through hole 11 and the outer surface of the signal contact pin 13 are provided with gradations ensuring the firm hold of the signal pin 13 in the through hole 11.

Zu beiden Enden des Distanzstücks 10 bzw. 1O'' ist eine Umfangsnut 14, 14' vorgesehen, in die jeweils ein axial geschlitzter Klemmring 15, 15' eingelassen ist, der einen einwandfreien Kontakt zwischen dem Distanzstück 10 und dem angrenzenden Kontaktring 8, 8' gewährleistet. Analog sichern die Klemmkontakte, in die die zentralen Signalleiter 6, 6' auslaufen, einen einwandfreien Kontakt mit den Enden des Signalkontaktstifts 13.At both ends of the spacer 10 and 10 '' there is a circumferential groove 14, 14 ', into each of which an axially slotted clamping ring 15, 15' is inserted, which ensures perfect contact between the spacer 10 and the adjacent contact ring 8, 8 ' guaranteed. Similarly, the terminal contacts, into which the central signal conductors 6, 6 'run out, ensure perfect contact with the ends of the signal contact pin 13.

Die in Fig. 3 dargestellte Ausführung, bei der der Abstand von der Leiterplatten 1 und 1''' voneinander gleich dem Abstand der Leiterplatten 1 und 1'' in Fig. 1 ist, bedient sich zur elektrischen Leiterplattenverbindung auf der Seite der Leiterplatte 1 prinzipiell der gleichen Bauelemente, wie sie in Fig. 1 veranschaulicht sind.The embodiment shown in FIG. 3, in which the distance from the printed circuit boards 1 and 1 ″ ″ from one another is equal to the distance from the printed circuit boards 1 and 1 ″ in FIG. 1, uses the electrical printed circuit board connection on the side of the printed circuit board 1 in principle of the same components as are illustrated in FIG. 1.

Unterschiedlich ist, wie Fig. 3 zeigt, daß die obere Leiterplatte 1''' in diesem Fall mit Durchbrüchen zum Einlöten von hier die Durchbrüche durchsetzenden Kontaktstiften 4'' bzw. 7'', die an die Stelle der Lötzungen 4' bzw. 7' der Abschirmkontakte 3' bzw. des Signalleiters 6' treten, ausgestattet ist. In diesem Fall gehen die Kontaktstifte 4'' von einem hülsenförmigen Abschirm-Kontakt 3'' aus, der über einen Isolierkörper 2'' den den zentralen Signalleiter 6'' bildenden Kontaktstift 7'' einschließt.It is different, as shown in FIG. 3, that the upper circuit board 1 ″ ″ in this case with openings for soldering in contact pins 4 ″ or 7 ″ penetrating the openings here, which replace the soldering tongues 4 ′ and 7 'the shielding contacts 3' or the signal conductor 6 'occur. In this case, the contact pins 4 ″ start from a sleeve-shaped shielding contact 3 ″, which includes the contact pin 7 ″ forming the central signal conductor 6 ″ via an insulating body 2 ″.

Auf seinem der Lötkontaktseite abgewandten Ende läuft der Signalleiter 6'' analog in einen Klemmkontakt aus.On its end facing away from the solder contact side, the signal conductor 6 ″ ends analogously in a clamp contact.

Wie ersichtlich, ist in diesem Beispiel der gegenseitige Abstand der Umfangsnuten 14, 14' kleiner und das Distanzstück 10'' entsprechend kürzer als im Fall des in Fig. 1 rechts dargestellten Distanzstücks 10, jedoch genau so lang wie das in Fig. 1 links dargestellte Distanzstück 1O''. Dies ist auf den entsprechend geringeren gegenseitigen Abstand der Leiterplatten 1, 1''' im Vergleich zum gegenseitigen Abstand zwischen den Leiterplatten 1, 1' und damit den aus der Zeichnung ersichtlichen entsprechend geringeren Abstand der von den Isolierkörpern eines Koax-Verbinders bestimmten Kontaktflächen voneinander zurückzuführen. Weist das Distanzstück eine Länge b auf und besitzt die Kontaktfläche K von der benachbarten Leiterplatte einen Abstand k, dann gilt offensichtlich die Beziehung b = a - 2k

Figure imgb0001
. Wenn die Kontaktflächen K jeweils vorzugsweise durch die der Leiterplatte abgewandte Stirnfläche der Isolierkörper selbst gebildet sind, können in sehr rationeller Weise einheitlich bemessene Isolierkörper-Abschirmkontakt-Signalleiter-Einheiten in Verbindung mit den Leiterplatten Anwendung finden, unabhängig davon, in welchem Abstand a letztere voneinander angeordnet werden, da es genügt, Distanzstücke der Länge b = a - 2k
Figure imgb0002
 bereitzuhalten, um die Verbindung zwischen den vorerwähnten Einheiten und damit den Leiterplatten herzustellen.As can be seen, the mutual distance between the circumferential grooves 14, 14 'is smaller in this example and the spacer 10''is correspondingly shorter than in the case of the spacer 10 shown on the right in FIG. 1, but exactly as long as that shown on the left in FIG. 1 Spacer 1O ''. This is due to the correspondingly smaller mutual spacing of the printed circuit boards 1, 1 '''compared to the mutual spacing between the printed circuit boards 1, 1' and thus the correspondingly smaller spacing of the contact surfaces determined by the insulating bodies of a coax connector from the drawing . If the spacer has a length b and the contact surface K is at a distance k from the adjacent printed circuit board, then the relationship obviously applies b = a - 2k
Figure imgb0001
 . If the contact surfaces K are each preferably formed by the end face of the insulating body itself facing away from the printed circuit board, uniformly dimensioned insulating body shielding contact signal conductor units can be used in connection with the printed circuit boards, irrespective of the distance a between the latter as it is enough, spacers of length b = a - 2k
Figure imgb0002
 ready to make the connection between the aforementioned units and thus the circuit boards.

Würde beispielsweise der Abstand zwischen den Leiterplatten 1 und 1'' bzw. 1 und 1''' auf den der Leiterplatten 1 und 1' vergrößert, bräuchte lediglich das Distanzstück 10'' durch das Distanzstück 10 ersetzt zu werden.If, for example, the distance between the circuit boards 1 and 1 ″ or 1 and 1 ″ ″ were increased to that of the circuit boards 1 and 1 ′, only the spacer 10 ″ would need to be replaced by the spacer 10.
