Description

Die Erfindung bezieht sich auf eine koaxiale Steckvorrichtung entsprechend dem Oberbegriff des Patentanspruches.The invention relates to a coaxial connector according to the preamble of the claim.

Eine solche Steckvorrichtung ist in allen wesentlichen Einzelheiten aus der US-A-4 012 105 bekannt. Da die Kontaktfinger der einen Aussenleiterhülse bei dieser bekannten Koaxialsteckvorrichtung gerade und ohne Vorbiegung verlaufen, hat der von den Ansätzen der Kontaktfinger gebildete Kontaktwulst einen maximalen Radius, der grösser ist, als der Radius der lichten Weite der anderen Aussenleiterhülse in deren hohlzylindrischem Abschnitt. Im gesteckten Zustand werden daher die Kontaktfinger mit ihren freien Enden nach innen gebogen. Diese Biegung darf jedoch nur ganz geringfügig sein, weil sich sonst Schwierigkeiten bei der Kontaktgabe zwischen den Aussenleiterhülsen und beim Einstecken der Kontaktfinger in die andere Aussenleiterhülse ergeben können.Such a plug device is known in all essential details from US-A-4 012 105. Since the contact fingers of one outer conductor sleeve run straight and without pre-bending in this known coaxial plug-in device, the contact bead formed by the approaches of the contact fingers has a maximum radius which is larger than the radius of the inside diameter of the other outer conductor sleeve in the hollow cylindrical section thereof. When plugged in, the contact fingers are therefore bent inwards with their free ends. However, this bend may only be very slight, because otherwise difficulties can arise when making contact between the outer conductor sleeves and when inserting the contact fingers into the other outer conductor sleeve.

Demgegenüber ist es Aufgabe vorliegender Erfindung eine Koaxialsteckvorrichtung der eingangs genannten Art derart auszubilden, dass die Einwärtsbiegung der freien Enden der Kontaktfinger im Hinblick auf eine kapazitive Kompensation der induktiven Störzonen im Steckbereich gewählt werden kann, ohne dabei Störungen in der Kontaktgabe zwischen den Aussenleiterhülsen befürchten zu müssen.In contrast, it is an object of the present invention to design a coaxial plug-in device of the type mentioned at the outset in such a way that the inward bending of the free ends of the contact fingers can be selected with a view to capacitive compensation of the inductive interference zones in the plug-in area, without having to fear interference in the contact between the outer conductor sleeves .

Erfindungsgemäss ergibt sich die Lösung dieser Aufgabe dadurch, dass bei einer koaxialen Steckvorrichtung der eingangs genannten Art der äussere Krümmungsradius der Kontaktfinger im Bereich des Kontaktwulstes gleich der halben lichten Weite der anderen Aussenleiterhülse im hohlzylindrischen Bereich dieser Hülse ist.According to the invention, this object is achieved in that, in the case of a coaxial plug-in device of the type mentioned at the outset, the outer radius of curvature of the contact fingers in the region of the contact bead is equal to half the inside width of the other outer conductor sleeve in the hollow cylindrical region of this sleeve.

Auch bei einer relativ grossen Einwärtsbiegung der freien Enden der Kontaktfinger in der anderen Aussenleiterhülse erhält man dadurch einen grossflächig der Innenseite der anderen Aussenleiterhülse anliegenden Ringwulst, der einem idealen Ringkontakt nahekommt und vermeidet dadurch Schwierigkeiten beim Zusammenfügen der beiden Steckvorrichtungshälften.Even with a relatively large inward bend in the free ends of the contact fingers in the other outer conductor sleeve, this results in a ring bulge which lies over a large area of the inside of the other outer conductor sleeve and which comes close to an ideal ring contact and thereby avoids difficulties in joining the two connector halves.

Nachfolgend wird anhand von drei Figuren ein Ausführungsbeispiel der Erfindung noch näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to three figures.

Die Figuren zeigen, unter Weglassung aller nicht unbedingt zum Verständnis der Erfindung erforderlichen Einzelheiten, vergrössert, in Schräg- und Seitenansicht und teilweise im Schnitt, die beiden Steckvorrichtungshälften einer koaxialen Steckvorrichtung nach der Erfindung im ungesteckten (Fig. 1) und im gesteckten Zustand (Fig. 2), sowie das freie Ende eines Kontaktfingers (Fig. 3).The figures show, omitting all details that are not absolutely necessary for understanding the invention, enlarged, in oblique and side view and partly in section, the two connector halves of a coaxial connector according to the invention in the unmated (FIG. 1) and in the inserted state (FIG . 2), and the free end of a contact finger (Fig. 3).

Im einzelnen ist den Figuren zu entnehmen, dass jede Steckvorrichtungshälfte der dargestellten koaxialen Steckvorrichtung aus einer Aussenleiterhülse 1, 2 und einem Innenleiterkontaktorgan 7, 8 besteht.The figures show in detail that each plug device half of the coaxial plug device shown consists of an outer conductor sleeve 1, 2 and an inner conductor contact element 7, 8.

Die Aussenleiterhülsen 1, 2 sind auf ihren voneinander abgewandten Seiten z.B. jeweils mit dem Aussenleiter eines Koaxialkabels auf nicht näher dargestellte Weise verbunden, und die Innenleiterkontaktorgane 7, 8 jeweils an die Innenleiter der betreffenden Koaxialkabel angeschlossen.The outer conductor sleeves 1, 2 are e.g. each connected to the outer conductor of a coaxial cable in a manner not shown, and the inner conductor contact members 7, 8 each connected to the inner conductor of the coaxial cable concerned.

Um zwischen den beiden Aussenleiterhülsen 1, 2 einen hochfrequenzmässig einwandfreien Kontakt herzustellen, ist die der einen Steckvorrichtungshälfte zugeordnete Aussenleiterhülse 1 in einem Abschnitt 9, der der Aussenleiterhülse 2 der anderen Steckvorrichtungshälfte zugewandt ist, durch zur Achse 4 der einen Steckvorrichtungshälfte parallele Schlitze in Kontaktfinger 3 aufgeteilt, die gleichmässig über den Umfang der Aussenleiterhülse 1 verteilt sind.In order to establish a high-frequency contact between the two outer conductor sleeves 1, 2, the outer conductor sleeve 1 assigned to the one connector device half is divided in a section 9, which faces the outer conductor sleeve 2 of the other connector device half, by slots parallel to the axis 4 of the one connector device half in contact fingers 3 which are evenly distributed over the circumference of the outer conductor sleeve 1.

An ihren freien Enden weisen die Kontaktfinger radial nach aussen gerichtete Ansätze 5 auf, die zusammen einen ringförmigen Kontaktwulst 11 bilden.At their free ends, the contact fingers have radially outward projections 5, which together form an annular contact bead 11.

Die Kontaktfinger 3 erstrecken sich ohne jede Vorbiegung oder Vorspannung parallel zur Achse 4 der Aussenleiterhülse 1.The contact fingers 3 extend parallel to the axis 4 of the outer conductor sleeve 1 without any pre-bending or pre-tensioning.

Die Aussenleiterhülse 2 der anderen Steckvorrichtungshälfte ist auf ihrer, den Kontaktfingern 3 der Aussenleiterhülse 1 zugewandten Seite mit einem Mündungsabschnitt 6 versehen, in dessen Bereich sich die lichte Weite der Kontakthülse 2 konisch erweitert. Dabei ist die grösste lichte Weite des Mündungsabschnittes 6 grösser bemessen, als der maximale Aussendurchmesser des Kontaktwulstes 11, der durch die Ansätze 3 der einzelnen Kontaktfinger 3 gebildet wird. Dagegen ist die lichte Weite der Aussenleiterhülse 2 in einem an den Mündungsabschnitt anschliessenden Bereich 12 der Aussenleiterhülse 2, in der diese Hülse einen zylindrischen Innenraum aufweist, geringfügig kleiner bemessen als der Aussendurchmesser des Kontaktwulstes 11.The outer conductor sleeve 2 of the other plug device half is provided on its side facing the contact fingers 3 of the outer conductor sleeve 1 with a mouth section 6, in the area of which the clear width of the contact sleeve 2 widens conically. The greatest clear width of the mouth section 6 is larger than the maximum outer diameter of the contact bead 11, which is formed by the lugs 3 of the individual contact fingers 3. In contrast, the clear width of the outer conductor sleeve 2 in a region 12 of the outer conductor sleeve 2 adjoining the mouth section, in which this sleeve has a cylindrical interior, is dimensioned slightly smaller than the outer diameter of the contact bead 11.

Infolgedessen drängt der konische Mündungsabschnitt 6 beim Ineinanderstecken der beiden Aussenleiterhülsen die Ansätze 5 der Kontaktfinger 3 gegen die Achse 4 der Hülse 1. Dadurch werden die Finger 3 endseitig gegen die Achse 4 gebogen. Infolgedessen werden die Ansätze 5 federnd gegen die Innenwand der Hülse 2 gedrückt, wenn die Hülse 1 mit den Kontaktfingern 3 in die Hülse 2 eingeschoben ist und dabei die Endstellung der beiden Hülsen im zusammengesteckten Zustand erreicht worden ist.As a result, the conical opening section 6 urges the projections 5 of the contact fingers 3 against the axis 4 of the sleeve 1 when the two outer conductor sleeves are inserted into one another. As a result, the fingers 3 are bent at the end against the axis 4. As a result, the lugs 5 are pressed resiliently against the inner wall of the sleeve 2 when the sleeve 1 with the contact fingers 3 is inserted into the sleeve 2 and the end position of the two sleeves in the assembled state has been reached.

Auf diese Weise verlaufen die Kontaktfinger 3 innerhalb der Hülse 2 zu ihren freien Enden hin leicht nach innen gekrümmt und verkleinern dabei den Abstand zwischen der Hülse 1 und den ineinanderstekkenden Innenleiterkontaktorganen 7, 8 der Steckvorrichtung.In this way, the contact fingers 3 inside the sleeve 2 run slightly inward towards their free ends and thereby reduce the distance between the sleeve 1 and the nested internal conductor contact members 7, 8 of the plug device.

Die auf diese Weise erzeugte kapazitiv wirkende Störung im Steckbereich kompensiert vorteilhaft induktive Störzonen, die z.B. durch die Schlitze 10 in der Aussenleiterhülse 1 und in der Innenleiterbuchse 8, sowie durch den Spalt 13 zwischen Innenleiterbuchse 8 und Innenleiterstift 7 gebildet werden.The capacitive interference in the plug-in area generated in this way advantageously compensates for inductive interference zones, e.g. through the slots 10 in the outer conductor sleeve 1 and in the inner conductor bushing 8, and through the gap 13 between the inner conductor bushing 8 and the inner conductor pin 7.

Dadurch, dass die einzelnen Abschnitte des Kontaktwulstes 11 am freien Ende der Kontaktfinger 3 mit einem äusseren Krümmungsradius R versehen sind, der der halben lichten Weite der anderen Aussenleiterhülse 2 im hohlzylindrischen Abschnitt 12 entspricht, ist gewährleistet, dass zwischen dem-Kontaktwulst 11 und der Aussenleiterhülse 2 ein einwandfreier Ringkontakt gebildet wird, obwohl die Kontaktfinger beim Zusammenfügen der beiden Steckvorrichtungshälften gegen die Achse der Steckvorrichtung gebogen werden.The fact that the individual sections of the contact bead 11 at the free end of the contact fingers 3 are provided with an outer radius of curvature R, which corresponds to half the inside width of the other outer conductor sleeve 2 in the hollow cylindrical section 12, ensures that between the contact bead 11 and the outer conductor sleeve 2 a perfect ring contact is formed, although the contact fingers when joining the two Connector halves are bent against the axis of the connector.
