Description

Die vorliegende Erfindung betrifft einen Koaxialsteckverbinder mit Schnellverriegelung, welcher zur Aufnahme eines komplementären Koaxialsteckverbinders ausgebildet ist, wobei Koaxialsteckverbinder und komplementärer Koaxialsteckverbinder mit einem Kupplungsorgan der Schnellverriegelung miteinander verbindbar sind, wobei der Koaxialsteckverbinder und der komplementäre Koaxialsteckverbinder jeweils ein einen Innenleiter ausbildendes Innenleiterteil sowie ein einen Außenleiter ausbildendes Außenleiterteil aufweisen, wobei am Koaxialsteckverbinder ein Kontaktelement derart angeordnet ist, dass dieses bei zusammen gesteckten Koaxialsteckverbindern zwischen dem Außenleiterteil des Koaxialsteckverbinders und dem Außenleiterteil des komplementären Koaxialsteckverbinders angeordnet ist, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a coaxial connector with quick lock, which is designed to receive a complementary coaxial connector, wherein coaxial connector and complementary coaxial connector with a coupling member of the quick lock are connected to each other, wherein the coaxial connector and the complementary coaxial connector each having an inner conductor forming inner conductor part and an outer conductor ausbildendes Have outer conductor part, wherein the coaxial connector, a contact element is arranged such that it is arranged at coaxial plugged between the outer conductor part of the coaxial connector and the outer conductor part of the complementary coaxial connector, according to the preamble of claim 1.

Aus der EP 1337008 A2 ist ein elektrischer Steckverbinder mit Schnellverriegelung bekannt, der ein erstes Verbindungselement und ein zweites Verbindungselement aufweist, die mit einem Kupplungsorgan miteinander verbunden sind und einen Innenleiter sowie einen Außenleiter ausbilden. Ein Außenleiter des zweiten Verbindungselementes bildet stirnseitig einen elektrischen Kontakt, und zwischen dem ersten Verbindungselement und dem zweiten Verbindungselement ist ein federelastisches Kontaktelement angeordnet. Um einen genau definierten Kontakt mit guter passiver Intermodulation und geringer HF-Abstrahlung zu erzielen, ist das Kontaktelement als Ringscheibe ausgebildet, die unter axialer Spannung zwischen den beiden Außenleitern an diesen anliegt und umlaufende geschlossene Kontaktflächen ausbildet.From the EP 1337008 A2 is known an electrical connector with quick-lock, having a first connecting element and a second connecting element, which are connected to a coupling member with each other and form an inner conductor and an outer conductor. An outer conductor of the second connecting element forms an electrical contact on the front side, and a spring-elastic contact element is arranged between the first connecting element and the second connecting element. In order to achieve a well-defined contact with good passive intermodulation and low RF radiation, the contact element is designed as an annular disc, which rests against the axial voltage between the two outer conductors of these and forms circumferential closed contact surfaces.

Diese Anordnung hat jedoch den Nachteil, dass es weder eine definierte Kontaktebene noch eine definierte Kontaktzone gibt. Dies liegt vor allem daran, dass der für den Schnellverschluss erforderliche Längenausgleich und die Kontaktierung selbst an ein und derselben Stelle erfolgen. Hierdurch kann sich die Kontaktstelle an unterschiedlichen Orten befinden und der exakte Verlauf des Stromes entlang des Außenleiters des elektrischen Steckverbinders ist an dieser Stelle weder vorherbestimmt noch vorhersehbar. Dies beeinträchtigt die HF-Eigenschaften dieser Steckverbindung ganz erheblich.However, this arrangement has the disadvantage that there is neither a defined contact plane nor a defined contact zone. This is mainly due to the fact that the length compensation required for the quick release and the contacting itself are carried out at one and the same location. As a result, the contact point can be located at different locations and the exact course of the current along the outer conductor of the electrical connector is neither predetermined nor predictable at this point. This significantly affects the RF characteristics of this connector.

Ferner wird auf US 2003/0027435A1 verwiesen, das alle Merkmale des Oberbegriffs von Anspruch 1 offenbart.Further, on US 2003 / 0027435A1 which discloses all features of the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der o.g. Art bezüglich Kontaktierung und HF-Eigenschaften zu verbessern.The invention has for its object to provide a connector of o.g. Type with respect to contacting and RF characteristics to improve.

Diese Aufgabe wird erfindungsgemäß durch einen Steckverbinder der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a connector of o.g. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.

Bei einem Koaxialsteckverbinder der o.g. Art ist erfindungsgemäß vorgesehen, dass das Kontaktelement als Hülse mit einem ersten Ende und einem zweiten Ende ausgebildet ist, wobei ein erstes Ende der Hülse einen ersten elektrischen Kontakt für einen stirnseitigen Kontaktbereich des Außenleiterteiles des komplementären Koaxialsteckverbinders und ein zweites Ende der Hülse einen zweiten elektrischen Kontakt mit dem Außenleiterteil des Koaxialsteckverbinders ausbildet, und dass ein elastisches, elektrisch nicht leitendes Längenausgleichselement vorgesehen ist, welches mit einer ersten Seite an dem Außenleiterteil des Koaxialsteckverbinders und mit einer gegenüberliegenden zweiten Seite an der Hülse in einem Bereich beabstandet von den elektrischen Kontakten anschlägt.In a coaxial connector of o.g. Art is inventively provided that the contact element is formed as a sleeve having a first end and a second end, wherein a first end of the sleeve has a first electrical contact for a frontal contact region of the outer conductor part of the complementary coaxial connector and a second end of the sleeve has a second electrical contact formed with the outer conductor part of the coaxial connector, and that an elastic, electrically non-conductive length compensation element is provided which abuts with a first side on the outer conductor part of the coaxial connector and with an opposite second side on the sleeve in a region spaced from the electrical contacts.

Dies hat den Vorteil, dass die Funktion der Außenleiterkontaktierung einerseits und des Längenausgleichs für die Schnellverriegelung andererseits räumlich voneinander getrennt ausgebildet sind. Hierdurch ist der Stromfluss entlang der Außenleiterteile der Steckverbindung definiert und vorhersehbar. Dies hat verbesserte HF-Eigenschaften der Steckverbindung zufolge.This has the advantage that the function of the Außenleiterkontaktierung on the one hand and the length compensation for the quick lock on the other hand are spatially separated. As a result, the current flow along the outer conductor parts of the connector is defined and predictable. This has improved RF characteristics of the connector.

Einen maximalen Längenausgleich in axialer Richtung erzielt man dadurch, dass das Längenausgleichselement derart angeordnet ist, dass es bei miteinander verbundenen Koaxialsteckverbindern in axialer Richtung zwischen Hülse und Außenleiterteil des Koaxialsteckverbinders eingespannt ist.A maximum length compensation in the axial direction is achieved in that the length compensation element is arranged such that it is clamped in interconnected Koaxialsteckverbindern in the axial direction between the sleeve and outer conductor part of the coaxial connector.

Zweckmäßigerweise schlägt das Längenausgleichselement mit der ersten Seite an einer Stirnseite des Außenleiterteiles des Koaxialsteckverbinders an.Conveniently, the length compensation element strikes with the first side on an end face of the outer conductor part of the coaxial connector.

Bevorzugt ist der zweite elektrische Kontakt in radialer Richtung zwischen der Hülse und dem Außenleiterteil des Koaxialsteckverbinders und bei zusammen gesteckten Koaxialsteckverbindern der erste elektrische Kontakt in axialer Richtung zwischen der Hülse und dem Außenleiterteil des komplementären Koaxialsteckverbinders ausgebildet.Preferably, the second electrical contact is formed in the radial direction between the sleeve and the outer conductor part of the coaxial connector and, when the coaxial connectors are plugged together, the first electrical contact in the axial direction between the sleeve and the outer conductor part of the complementary coaxial connector.

In einer besonders bevorzugten Ausführungsform weist die Hülse an dem ersten Ende einen sich radial nach außen erhebenden Bund auf und ist an dem dem Bund gegenüberliegenden zweiten Ende axial geschlitzt, so dass in radialer Richtung elastisch auslenkbare Kontaktfinger ausgebildet sind. In dem Außenleiterteil des Koaxialsteckverbinders ist bevorzugt eine Ausnehmung ausgebildet, wobei das zweite Ende der Hülse wenigstens mit den Kontaktfingern derart in die Ausnehmung eingreift und mit dieser zusammenwirkt, dass bei zusammengesteckten Koaxialsteckverbindem der stirnseitige elektrische Kontakt des Außenleiterteiles des komplementären Koaxialsteckverbinders an dem Bund der Hülse anschlägt, wodurch der erste elektrische Kontakt zwischen dem Außenleiterteil des komplementären Koaxialsteckverbinders und dem Bund der Hülse mit einer Kontaktfläche und einer durch eine Schließkraft der Schnellverriegelung axial aufgebrachten Kontaktkraft hergestellt ist, und wenigstens ein Kontaktfinger elastisch radial ausgelenkt ist sowie das Außenleiterteil des Koaxialsteckverbinders kontaktierend berührt, wodurch der zweite elektrische Kontakt zwischen dem Außenleiterteil des Koaxialsteckverbinders und dem Kontaktfinger der Hülse mit einer Kontaktfläche und einer durch die elastische Rückstellkraft des Kontaktfingers radial aufgebrachten Kontaktkraft hergestellt ist. An dem Außenleiterteil des Koaxialsteckverbinders ist zweckmäßigerweise ein dem Bund der Hülse zugewandter Anschlag ausgebildet, wobei zwischen dem Bund der Hülse und dem Anschlag am Außenleiterteil des Koaxialsteckverbinders das Längenausgleichselement angeordnet ist.In a particularly preferred embodiment, the sleeve at the first end on a radially outwardly rising collar and is axially slotted at the second end opposite the collar, so that in the radial direction elastically deflectable contact fingers are formed. In the outer conductor part of the coaxial connector, a recess is preferably formed, wherein the second end of the sleeve engages at least with the contact fingers in the recess and cooperates with this, that mated with Koaxialsteckverbindem the frontal electrical contact of the outer conductor part of the complementary coaxial connector abuts the collar of the sleeve whereby the first electrical contact between the outer conductor part of the complementary coaxial connector and the collar of the sleeve is made with a contact surface and a contact force applied axially by a closing force of the quick lock, and at least one contact finger is elastically radially deflected, contacting the outer conductor part of the coaxial connector in contact the second electrical contact between the outer conductor part of the coaxial connector and the contact finger of the sleeve with a contact surface and one through the elastic restoring force of the contact finger radially applied contact force is made. On the outer conductor part of the coaxial connector expediently a collar of the sleeve facing stop is formed, wherein between the collar of the sleeve and the stop on the outer conductor part of the coaxial connector, the length compensation element is arranged.

Zweckmäßigerweise ist der Anschlag am Außenleiterteil des Koaxialsteckverbinders ringförmig ausgebildet.Conveniently, the stop on the outer conductor part of the coaxial connector is annular.

Beispielsweise ist die Ausnehmung im Außenleiterteil des Koaxialsteckverbinders in radialer Richtung nach innen zu einem Isolierteil des Innenleiterteiles des Koaxialsteckverbinders hin offen, sodass die Hülse auf dem Isolierteil des Innenleiterteiles des Koaxialsteckverbinders aufliegt.For example, the recess in the outer conductor part of the coaxial connector in the radial direction inwardly to an insulating part of the inner conductor part of the coaxial connector is open, so that the sleeve rests on the insulating part of the inner conductor part of the coaxial connector.

Zum Herstellen eines sicheren elektrischen Kontaktes zwischen der Hülse und dem Außenleiterteil des ersten Verbinderelementes weist die Hülse an freien Enden der Kontaktfinger sich radial nach außen erhebende Erhebungen auf, welche an einer Innenfläche des Außenleiterteiles des Koaxialsteckverbinders elektrisch kontaktierend anschlagen und eine derartige Höhe aufweisen, dass der jeweilige Kontaktfinger elastisch radial nach innen ausgelenkt ist.To produce a secure electrical contact between the sleeve and the outer conductor part of the first connector element, the sleeve has at free ends of the contact fingers on radially outward elevations, which strike against an inner surface of the outer conductor part of the coaxial connector electrically contacting and have a height such that the respective contact fingers is elastically deflected radially inward.

Beispielsweise ist der komplementäre Koaxialsteckverbinder als Koaxialbuchse bzw. Koaxialkuppler und der Koaxialsteckverbinder als Koaxialstecker ausgebildet.For example, the complementary coaxial connector is designed as a coaxial jack or coaxial coupler and the coaxial connector as a coaxial connector.

Die in Fig. 1 und 2 dargestellte bevorzugte Ausführungsform einer erfindungsgemäßen Koaxialsteckverbindung umfasst ein erstes Verbinderelement 10 (Koaxialsteckverbinder) in Form eines Koaxialsteckers und ein zweites Verbinderelement 12 (komplementärer Koaxialsteckverbinder) in Form eines Koaxialkupplers. Das erste Verbinderelement 10 umfasst ein einen Außenleiter ausbildendes Außenleiterteil 14 und ein einen Innenleiter ausbildendes Innenleiterteil 16. Das zweite Verbinderelement 12 umfasst ein einen Außenleiter ausbildendes Außenleiterteil 18 und ein einen Innenleiter ausbildendes Innenleiterteil 20. Das Innenleiterteil 16 des ersten Verbinderelementes 10 ist von einem ersten Isoliertstoffteil 26 umgeben. Zwischen dem Außenleiterteil 18 des zweiten Verbinderelementes 12 und dem Innenleiterteil 20 des zweiten Verbinderelementes 12 ist ein zweites Isoliertstoffteil 24 angeordnet. Die beiden Verbinderelemente 10 und 12 sind mit einem Kupplungsorgan 28 lösbar miteinander verbunden. Das Kupplungsorgan 28 weist in an sich bekannter Weise einen Verriegelungsring 30 auf, der in eine Aussennut 32 des zweiten Verbinderelementes 12 eingreift und an einer Schulter 34 des ersten Verbinderelementes 10 und an einem Halterrand 36 ansteht. Um die Verriegelung zu lösen, wird eine Verriegelungshülse 38 in Richtung des Pfeiles 40 und somit in Fig. 1 von oben nach unten verschoben. Mit einem umlaufenden inneren Rand wird der Verriegelungsring 30 aus der Aussennut 32 herausgehoben und damit die Verriegelung gelöst. Beim Zusammenstecken der beiden Verbinderelemente 10 und 12 rastet der Verriegelungsring 30 selbsttätig in die Nut 32 ein.In the Fig. 1 and 2 illustrated preferred embodiment of a coaxial connector according to the invention comprises a first connector element 10 (coaxial connector) in the form of a coaxial connector and a second connector element 12 (complementary coaxial connector) in the form of a coaxial coupler.

The second connector element 12 comprises an outer conductor part 18 forming an outer conductor and an inner conductor part 20 forming an inner conductor. The inner conductor part 16 of the first connector element 10 is of a first insulating material part 26 surrounded. Between the outer conductor part 18 of the second connector element 12 and the inner conductor part 20 of the second connector element 12, a second Isolierstoffteil 24 is arranged. The two connector elements 10 and 12 are detachably connected to each other with a coupling member 28. The coupling member 28 has in a conventional manner a locking ring 30 which engages in an outer groove 32 of the second connector element 12 and abuts a shoulder 34 of the first connector element 10 and a holder edge 36. To release the lock, a locking sleeve 38 in the direction of arrow 40 and thus in Fig. 1 moved from top to bottom. With a peripheral inner edge of the locking ring 30 is lifted out of the outer groove 32 and thus solved the lock. When mating the two connector elements 10 and 12 of the locking ring 30 automatically engages in the groove 32 a.

Um die Toleranz des Kupplungsorgans 28 zu kompensieren und um gute HF-Eigenschaften zu erreichen, ist ein Kontaktelement 44 vorgesehen, das zwischen dem Außenleiterteil 14 des ersten Verbinderelementes 10 und dem Außenleiterteil 18 des zweiten Verbinderelementes 12 angeordnet ist. Wie aus Fig. 3 ersichtlich, ist das Kontaktelement 44 als Hülse ausgebildet, die an einem ersten Ende 46 einen sich radial nach außen erhebenden Bund 48 aufweist und an einem dem Bund 48 gegenüberliegenden zweiten Ende 50 axial geschlitzt ist, so dass in radialer Richtung elastisch auslenkbare Kontaktfinger 52 ausgebildet sind. An den freien Enden der Kontaktfinger 52 sind sich radial nach außen erhebende Erhebungen 54 ausgebildet.In order to compensate for the tolerance of the coupling member 28 and to achieve good RF characteristics, a contact element 44 is provided, which is arranged between the outer conductor part 14 of the first connector element 10 and the outer conductor part 18 of the second connector element 12. How out Fig. 3 can be seen, the contact element 44 is formed as a sleeve having a radially outwardly rising collar 48 at a first end 46 and is axially slotted at a second end 50 opposite the collar 48, so that in the radial direction elastically deflectable contact fingers 52 are formed. At the free ends of the contact fingers 52 are radially upwardly rising elevations 54 are formed.

Die Anordnung der Hülse 44 im Koaxialsteckverbinder ist aus den Fig. 1 und 2 näher ersichtlich. Die Hülse 44 greift mit ihrem zweiten Ende 50, d. h. im Wesentlichen mit den Kontaktfingern 52, in eine an einer Innenseite des Außenleiterteiles 14 des ersten Verbinderelementes 10 ausgebildete Ausnehmung 58 ein. Im Bereich der Ausnehmung 58 schlagen die Erhebungen 54 der Hülse 44 an die Innenseite des Außenleiterteiles 14 des ersten Verbinderelementes 10 an. Der Innendurchmesser der Ausnehmung 58 ist dabei derart gewählt, dass er kleiner ist als der Außendurchmesser der Hülse 44 im Bereich der Erhebungen 54. Dies hat zur Folge, dass bei in die Ausnehmung 58 eingeschobener Hülse 44 die Kontaktfinger 52 radial nach innen elastisch ausgelenkt sind. Auf diese Weise ergibt sich im Bereich der Anlage der Erhebungen 54 in der Ausnehmung 58 ein zweiter elektrische Kontakt mit einer Kontaktfläche und einer durch die elastische Rückstellkraft der elastisch radial nach innen ausgelenkten Kontaktfinger 52 aufgebrachte Kontaktkraft. Die Hülse 44 ist in axialer Richtung relativ zum Außenleiterteil 14 des Verbinderelementes 10 verschiebbar. Durch eine Kante 66 am ersten Isolierstoffteil 26 ist die Hülse 44 koaxial zum ersten Isolierstoffteil 26 gehalten und kann nicht in axialer Richtung heraus fallen. Die Hülse 44 ist daher in der Ausnehmung 58 unverlierbar montiertThe arrangement of the sleeve 44 in the coaxial connector is from the Fig. 1 and 2 closer. The sleeve 44 engages with its second end 50, ie essentially with the contact fingers 52, in a recess 58 formed on an inner side of the outer conductor part 14 of the first connector element 10. In the region of the recess 58, the elevations 54 of the sleeve 44 strike against the inside of the outer conductor part 14 of the first connector element 10. The inner diameter of the recess 58 is chosen such that it is smaller than the outer diameter of the sleeve 44 in the region of the elevations 54. This has the consequence that when inserted into the recess 58 sleeve 44, the contact fingers 52 are deflected radially inwardly elastic. In this way, results in the area of the system of the elevations 54 in the recess 58, a second electrical contact with a contact surface and a force applied by the elastic restoring force of the elastically radially inwardly deflected contact fingers 52 contact force. The sleeve 44 is displaceable in the axial direction relative to the outer conductor part 14 of the connector element 10. By an edge 66 on the first insulating part 26, the sleeve 44 is held coaxially with the first insulating part 26 and can not fall out in the axial direction. The sleeve 44 is therefore captively mounted in the recess 58

Am ersten Ende 46 der Hülse 44 schlägt der Bund 48 an eine Stirnfläche 60 des Außenleiterteiles 18 des zweiten Verbinderelementes 12 an. Diese Stirnfläche 60 bildet einen stirnseitigen elektrischen Kontakt aus. Durch das Kupplungsorgan 28 in Form einer Schnellverriegelung wird diese Stirnfläche 60 axial gegen den Bund 48 der Hülse 44 gedrückt. Zusätzlich ist am Außenleiterteil 14 des ersten Verbinderelementes 10 eine dem Bund 48 der Hülse 44 zugewandte Schulter 62 ausgebildet. Zwischen der Schulter 62 und dem Bund 48 der Hülse 44 ist ein elastisches Längenausgleichselement 64 angeordnet. Dieses Längenausgleichselement 64 ist beispielsweise als elektrisch nicht leitender O-Ring ausgebildet und stellt durch seine Anordnung axial zwischen dem Bund 48 der Hülse 44 und der Schulter 62 des Außenleiterteiles 14 des Verbindungselementes 10 in axialer Richtung einen Längenausgleich zur Verfügung, indem das Längenausgleichselement 64 mehr oder weniger stark in axialer Richtung zusammengequetscht wird. Durch die in axialer Richtung wirkende Schließkraft des Kupplungsorgans 28 wird die Stirnfläche 60 des Außenleiterteiles 18 des zweiten Verbinderelementes 12 in axialer Richtung gegen den Bund 48 und gegen die elastische Verformbarkeit des Längenausgleichselementes 64 gedrückt. Hierdurch wird zwischen der Stirnfläche 60 und dem Bund 48 ein erster elektrischer Kontakt mit Kontaktfläche und durch die Schließkraft des Kupplungsorgans 28 in axialer Richtung aufgebrachter Kontaktkraft hergestellt.At the first end 46 of the sleeve 44, the collar 48 abuts against an end face 60 of the outer conductor part 18 of the second connector element 12. This end face 60 forms a frontal electrical contact. By the coupling member 28 in the form of a quick locking this end face 60 is pressed axially against the collar 48 of the sleeve 44. In addition, on the outer conductor part 14 of the first connector element 10, a collar 48 of the sleeve 44 facing the shoulder 62 is formed. Between the shoulder 62 and the collar 48 of the sleeve 44, an elastic length compensation element 64 is arranged. This length compensation element 64 is formed for example as an electrically non-conductive O-ring and provides by its arrangement axially between the collar 48 of the sleeve 44 and the shoulder 62 of the outer conductor part 14 of the connecting element 10 in the axial direction a length compensation available by the length compensation element 64 more or less strong in the axial direction squeezed together. By acting in the axial direction closing force of the coupling member 28, the end face 60 of the outer conductor part 18 of the second connector element 12 is pressed in the axial direction against the collar 48 and against the elastic deformability of the length compensation element 64. As a result, a first electrical contact with contact surface and by the closing force of the coupling member 28 in the axial direction applied contact force is produced between the end face 60 and the collar 48.

Die in Fig. 3 bis 5 dargestellte bevorzugte Ausführungsform der Hülse 44 ist als Drehteil ausgebildet. Alternativ kann diese Hülse jedoch auch als sog. Biege-Stanzteil ausgebildet sein, wobei diese dann einen sich über die gesamte axiale Länge der Hülse 44 erstreckenden Schlitz aufweisen können.In the Fig. 3 to 5 illustrated preferred embodiment of the sleeve 44 is formed as a rotating part. Alternatively, however, this sleeve may also be designed as a so-called. Bending stamped part, which may then have a over the entire axial length of the sleeve 44 extending slot.
