Die vorliegende Erfindung betrifft einen Koaxialsteckverbinder, insbesondere Koaxialstecker oder Koaxialbuchse, mit einem Außenleiterteil, einem Innenleiterteil, einem Dielektrikum, welches das Innenleiterteil innerhalb und koaxial zum Außenleiterteil an einer vorbestimmten axialen Position hält, und einem steckseitigen Ende zum steckenden elektrischen und mechanischen Verbinden von Innenleiterteil und Außenleiterteil mit jeweils einem Innenleiterteil und einem Außenleiterteil eines komplementären Koaxialsteckverbinders, wobei das Dielektrikum einen axialen Kanal mit einem vorbestimmten ersten radialen Durchmesser aufweist, in dem das Innenleiterteil angeordnet ist, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a coaxial connector, in particular coaxial or coaxial jack, with an outer conductor part, an inner conductor part, a dielectric which holds the inner conductor part inside and coaxial to the outer conductor part at a predetermined axial position, and a plug-side end for plugging electrical and mechanical connection of inner conductor part and External conductor part, each having an inner conductor part and an outer conductor part of a complementary coaxial connector, wherein the dielectric has an axial channel with a predetermined first radial diameter, in which the inner conductor part is arranged, according to the preamble of claim 1.
Bei derartigen Koaxialsteckverbindern ist es üblich zur Montage des Koaxialsteckverbinders das Innenleiterteil axial in den Kanal des Dielektrikums einzuschieben, bis sich das Innenleiterteil an der axialen vorbestimmten Position befindet. In dieser axialen vorbestimmten Position weist der Koaxialsteckverbinder an seinem steckseitigen Ende die korrekten Anschlussmaße auf. Durch Einschieben des Innenleiterteils mit zu hoher axialer Kraft kann es jedoch passieren, dass das Innenleiterteil über die axiale vorbestimmte Position hinaus geschoben wird. Der Koaxialsteckverbinder ist dann beschädigt und eine Übertragung von HF-Signalen über diesen Koaxialsteckverbinder ist nicht mehr einwandfrei möglich. Zusätzlich wird beim Einstecken dieses Koaxialsteckverbinders mit falschen Anschlussmaßen in einen komplementären Koaxialsteckverbinder auch dieser komplementäre Koaxialsteckverbinder beschädigt. Die Folge ist auch hier eine sehr schlechte Übertragung von HF-Signalen.In such coaxial connectors, it is common for mounting the coaxial connector to insert the inner conductor member axially into the channel of the dielectric until the inner conductor member is at the axial predetermined position. In this axial predetermined position, the coaxial connector has the correct connection dimensions at its plug-in end. By inserting the inner conductor part with too high axial force, however, it may happen that the inner conductor part is pushed beyond the axial predetermined position. The coaxial connector is then damaged and transmission of RF signals via this coaxial connector is no longer possible properly. In addition, when plugging this coaxial connector with wrong connection dimensions in a complementary coaxial connector also this complementary Coaxial connector damaged. The result here too is a very poor transmission of RF signals.

In dieser vorbestimmten axialen Position ragt das Innenleiterteil 12 derart in das steckseitige Ende 22, dass vorbestimmte Anschlussmaße vorhanden sind. Bei der Montage des Koaxialsteckverbinders wird das Innenleiterteil 12 von der dem steckseitigen Ende 22 abgewandten Ende her in das Dielektrikum 14 axial eingeschoben, bis die Rastnasen 26 spürbar und hörbar in die Ausnehmungen 28 einrasten.Inner conductor part 12 and outer conductor part 10 is formed in each case with an inner conductor part and outer conductor part of a complementary coaxial connector, not shown. In the dielectric 14, an axial channel 24 for axially inserting the inner conductor part 12 into the plug-side end 22 facing away from the end of the dielectric 14 is formed. On an outer side of the inner conductor part 12 elevations in the form of locking lugs 26 are formed and on a channel 24 facing inside of the dielectric 14 corresponding recesses 28 are formed and arranged such that the locking lugs 26 engage in the recesses 28 when the inner conductor part in a predetermined axial position relative to the outer conductor part. In this predetermined axial position, the inner conductor part 12 protrudes into the plug-side end 22 in such a way that predetermined connection dimensions are present. When mounting the coaxial connector, the inner conductor part 12 is axially inserted from the plug-side end 22 facing away from the end into the dielectric 14 until the locking lugs 26 noticeably and audibly engage in the recesses 28.
Der Kanal 24 des Dielektrikums weist einen ersten radialen Innendurchmesser 30 auf, welcher sich an dem steckseitigen Ende 22 konisch zu einem kleineren, zweiten radialen Innendurchmesser 32 verjüngt. Zusätzlich weist das Innenleiterteil 12 einen ersten Außendurchmesser 34 auf, welcher sich zu einem kleineren, zweiten Außendurchmesser 36 derart verjüngt, dass an der Außenseite des Innenleiterteils 12 eine Schulter 38 ausgebildet ist. Der erste Außendurchmesser 34 des Innenleiterteils 12 ist größer als der zweite radiale Innendurchmesser 32 des Kanals 24 ausgebildet. Auf diese Weise schlägt die Schulter 38 an der konischen Verjüngung des Kanals 24 an dessen steckseitigen Ende 22 an und kann dann in axialer Richtung nicht weiter verschoben werden. Die Schulter 38 auf dem Innenleiterteil 12 ist dabei derart in axialer Richtung angeordnet, dass sich das Innenleiterteil 12 an der vorbestimmten axialen Position befindet und die Rastnasen 26 in die Ausnehmungen 28 bereits eingerastet sind, wenn die Schulter 38 an der konischen Verjüngung des Kanals 24 an dessen steckseitigen Ende 22 anschlägt. Dies ist in Fig. 4 dargestellt. Auf diese Weise ist ein Einschieben des Innenleiterteils 12 in axialer Richtung über die vorbestimmte axiale Position hinaus in Richtung des steckseitigen Endes 22 auch bei hoher axialer Kraft wirksam vermieden. Dadurch ist sichergestellt, dass die Anschlussabmessungen am steckseitigen Ende 22 immer korrekt sind.The channel 24 of the dielectric has a first radial inner diameter 30, which tapers at the plug-side end 22 conically to a smaller, second radial inner diameter 32. In addition, the inner conductor part 12 has a first outer diameter 34, which tapers to a smaller, second outer diameter 36 such that a shoulder 38 is formed on the outer side of the inner conductor part 12. The first outer diameter 34 of the inner conductor part 12 is formed larger than the second inner radial diameter 32 of the channel 24. In this way, the shoulder 38 abuts against the conical taper of the channel 24 at its plug-side end 22 and can then not be moved further in the axial direction. The shoulder 38 on the inner conductor part 12 is arranged in such an axial direction that the inner conductor part 12 is located at the predetermined axial position and the locking lugs 26 are already engaged in the recesses 28 when the shoulder 38 at the conical taper of the channel 24 at whose plug-side end 22 abuts. This is shown in Fig. 4. In this way, an insertion of the inner conductor part 12 in the axial direction over the predetermined axial position beyond in the direction of the plug-side end 22 is effectively avoided even at high axial force. This is Ensure that the connection dimensions at the plug-in end 22 are always correct.
An dem dem steckseitigen Ende 22 gegenüberliegenden Ende des Koaxialsteckverbinders mit der Crimphülse 16 ist ein Koaxialkabel (nicht dargestellt) mit dem Koaxialsteckverbinder verbindbar. At the plug-side end 22 opposite end of the coaxial connector with the crimping sleeve 16 is a coaxial cable (not shown) connectable to the coaxial connector.
