Die Erfindung betrifft eine Außenleiteranordnung für einen Koaxial-Steckverbinder gemäß dem Oberbegriff des Patentanspruchs 1. Ferner betrifft die Erfindung ein Kontaktbauteil und ein Anschlussbauteil für eine derartige Außenleiteranordnung, einen Stecker umfassend einen derartigen Koaxial-Steckverbinder mit einer derartigen Außenleiteranordnung, einen Koaxial-Steckverbinder mit einer derartigen Außenleiteranordnung, und einen Bausatz zum Bilden eines derartigen Koaxial-Steckverbinders.The invention relates to an outer conductor arrangement for a coaxial connector according to the preamble of claim 1. Furthermore, the invention relates to a contact component and a connection component for such an outer conductor arrangement, a plug comprising such a coaxial connector with such an outer conductor arrangement, a coaxial connector with a such an outer conductor arrangement, and a kit for forming such a coaxial connector.

Koaxial-Steckverbinder dienen der lösbaren Verbindung von Koaxialkabeln. Koaxial-Steckverbinder sind wie Koaxialkabel koaxial ausgeführt, damit sie die Vorteile der Koaxialkabel aufweisen, nämlich geringe elektromagnetische Beeinflussung und Abstrahlung sowie gute elektrische Abschirmung sowie eine Impedanz, die derjenigen des angeschlossenen Koaxialkabels entspricht, um Reflexionen an der Übergangsstelle zwischen Koaxial-Steckverbinder und Koaxialkabel zu vermeiden. Unter einem Koaxialkabel, kurz auch Koaxkabel, wird dabei ein zweipoliges Kabel mit konzentrischem Aufbau verstanden, das einen Innenleiter (auch Seele genannt) aufweist, der in konstantem Abstand von einem hohlzylindrischen Außenleiter umgeben ist. Der Außenleiter schirmt den Innenleiter vor elektromagnetischer Störstrahlung ab. In dem Zwischenraum zwischen dem Innenleiter und dem Außenleiter ist ein Isolator oder Dielektrikum angeordnet.Coaxial connectors are used for the detachable connection of coaxial cables. Like coaxial cables, coaxial connectors are designed to be coaxial, so that they have the advantages of coaxial cables, namely low electromagnetic interference and radiation as well as good electrical shielding and an impedance that corresponds to that of the connected coaxial cable to prevent reflections at the transition point between coaxial connector and coaxial cable avoid. A coaxial cable, or coaxial cable for short, is understood to mean a two-pole cable with a concentric structure, which has an inner conductor (also called a core), which is surrounded at a constant distance by a hollow cylindrical outer conductor. The outer conductor shields the inner conductor from electromagnetic Interference radiation. An insulator or dielectric is arranged in the space between the inner conductor and the outer conductor.

Koaxial-Steckverbinder sind dazu ausgebildet, einen vorbestimmten Wellenwiderstand, z.B. vom 50 Ω, bereitzustellen, um eine reflexionsfreie Übertragung von HF-Signalen zu gewährleisten. Der Wellenwiderstand eines Koaxial-Steckverbinders hängt u.a. von dem Verhältnis des Innendurchmessers des Außenleiters und dem Durchmesser des Innenleiters ab. Eine elektrische Anbindung eines Koaxialkabels an einen Koaxial-Steckverbinder erfordert daher an die jeweiligen Innendurchmesser und Außendurchmesser des Koaxialkabels angepasste Koaxial-Steckverbinder. Dies erhöht aber den Fertigungs- und Logistikaufwand, z.B. bei der Herstellung vorkonfektionierter Kabelbäume, da eine Vielzahl von unterschiedlichen Koaxial-Steckverbindern für unterschiedliche Koaxialkabel bereitgehalten werden müssen. Ferner müssen derartige Koaxial-Steckverbinder unterschiedliche Anforderungen erfüllen, um zum einen einen guten elektrischen Kontakt herzustellen und zum anderen eine ausreichende mechanische Stabilität gewährleisten. Dies führt zu einem hohen Fertigungsaufwand bei der Herstellung derartiger Koaxial-Steckverbinder.Coaxial connectors are designed to have a predetermined characteristic impedance, e.g. of 50 Ω, to ensure a reflection-free transmission of RF signals. The wave resistance of a coaxial connector depends, among other things. on the ratio of the inner diameter of the outer conductor and the diameter of the inner conductor. An electrical connection of a coaxial cable to a coaxial connector therefore requires coaxial connectors adapted to the respective inside and outside diameters of the coaxial cable. However, this increases the manufacturing and logistics effort, e.g. in the manufacture of pre-assembled cable harnesses, since a large number of different coaxial connectors must be kept ready for different coaxial cables. Furthermore, such coaxial connectors have to meet different requirements, on the one hand to establish good electrical contact and on the other hand to ensure adequate mechanical stability. This leads to a high manufacturing effort in the manufacture of such coaxial connectors.

Weist eine Außenleiteranordnung für einen Koaxial-Steckverbinder ein Kontaktbauteil zum Verbinden mit einem Gegenstück des Koaxialsteckverbinders mit einem Anschlussbauteil zum Anbinden eines Außenleiters eines Koaxialkabels auf, weisen jedoch Anschlussbauteile zum Anbinden von Außenleitern eines Koaxialkabels mit unterschiedlichen Durchmessern angpasste Außenabmessungen auf. So weist z.B. ein Anschlussbauteil zum Anbinden eines Außenleiters mit einem ersten Durchmesser einen Außendurchmesser auf, der kleiner als der Außendurchmesser eines zweiten Außenleiters mit einem zweiten, größeren Durchmesser ist. Da jedoch das Kontaktbauteil z.B. zum Verbinden mit einem Anschlussbauteil zum Anbinden eines Außenleiters mit großem Durchmesser ausgebildet ist, ist bei einer Anbindung eines Außenleiters mit einem kleineren Durchmesser mit einem entsprechenden Anschlussbauteil ein guter elektrischer und/oder mechanischer Kontakt mit dem Kontaktbauteil nicht gegeben.If an outer conductor arrangement for a coaxial connector has a contact component for connecting to a counterpart of the coaxial connector with a connection component for connecting an outer conductor of a coaxial cable, however, connection components for connecting outer conductors of a coaxial cable with different diameters have adapted outer dimensions. For example, a connection component for connecting an outer conductor with a first diameter has an outer diameter that is smaller than the outer diameter of a second outer conductor with a second, larger diameter. However, since the contact component is designed, for example, to connect to a connection component for connecting an outer conductor with a large diameter, a good electrical and / or mechanical contact with the contact component is not provided when connecting an outer conductor with a smaller diameter to a corresponding connection component.

Der Erfindung liegt die Aufgabe zugrunde, einen Weg aufzuzeigen, wie die Kontaktqualität unabhängig vom Durchmesser des Außenleiters verbessert werden kann.The invention has for its object to show a way how the contact quality can be improved regardless of the diameter of the outer conductor.

Diese Aufgabe wird erfindungsgemäß durch eine Außenleiteranordnung für einen Koaxial-Steckverbinder der o.g. Art mit den in Patentanspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen beschrieben.This object is achieved by an outer conductor arrangement for a coaxial connector of the above. Type solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.

Dazu ist es bei einer Außenleiteranordnung für einen Koaxial-Steckverbinder vorgesehen, dass die Außenleiteranordnung zweiteilig ausgebildet ist, mit einem Kontaktbauteil zum elektrischen und mechanischen Verbinden mit einem Außenleiter eines Gegensteckverbinders und mit einem Anschlussbauteil zum elektrischen und mechanischen Verbinden mit einem Außenleiter eines Koaxialkabels, wobei das Kontaktbauteil und das Anschlussbauteil an einem Kontaktabschnitt elektrisch und mechanisch miteinander verbunden sind, wobei zwischen dem Kontaktbauteil und dem Anschlussbauteil ein Ausgleichsabschnitt zum Ausgleich von einer Bauteildifferenz im Bereich des Kontaktabschnittes angeordnet ist..For this purpose, it is provided in an outer conductor arrangement for a coaxial connector that the outer conductor arrangement is formed in two parts, with a contact component for electrical and mechanical connection to an outer conductor of a mating connector and with a connection component for electrical and mechanical connection with an outer conductor of a coaxial cable, the Contact component and the connection component are electrically and mechanically connected to one another at a contact section, a compensation section being arranged between the contact component and the connection component to compensate for a component difference in the region of the contact section.

Dies hat den Vorteil, dass durch den Ausgleichsabschnitt Unterschiede der Außenabmessungen verschiedener Anschlussbauteile für Koaxialkabel mit verschiedenen Durchmessern ausgeglichen werden können und somit unabhängig vom Innenleiter- bzw. Außenleiterdurchmesser eines anzubindenden Koaxialkabels eine gleichbleibende Kontaktqualität gewährleistet ist.This has the advantage that differences in the outer dimensions of different connection components for coaxial cables with different diameters can be compensated for by the compensating section and thus a constant contact quality is guaranteed regardless of the inner conductor or outer conductor diameter of a coaxial cable to be connected.

Erfindungsgemäß ist der Ausgleichsabschnitt durch einen umgefalzten Materialabschnitt des Anschlussbauteils gebildet, wobei der umgefalzte Materialabschnitt an einer radial nach innen gerichteten Fläche an dem Kontaktabschnitt anliegt. Somit ist das Anschlussbauteil mit dem Ausgleichsabschnitt einstückig ausgebildet und kann besonders einfach gefertigt werden.
Gemäß einer Ausführungsform ist der Ausgleichsabschnitt dem Anschlussbauteil zugeordnet. So kann durch Anpassung lediglich des Anschlussbauteils bzw. Auswahl eines passenden Anschlussbauteils aus einer Mehrzahl von Anschlussbauteilen für verschieden Durchmesser von Außenleitern die Kontaktqualität gesteigert werden. Gemäß einer weiteren Ausführungsform ist der umgefalzte Materialabschnitt zumindest abschnittsweise geprägt. So kann durch vorheriges Prägen des Materialabschnitts abschnittsweise mit einer reduzierten Materialstärke versehen werden, so dass der umgefalzte Materialabschnitt eine Materialstärke aufweisen kann, die zwischen der Materialstärke des ungefalzten Materialabschnitt und der doppelten Materialstärke liegt.According to the invention, the compensating section is formed by a folded-over material section of the connection component, the folded-over material section resting against the contact section on a radially inwardly directed surface. The connecting component is thus formed in one piece with the compensating section and can be manufactured particularly easily.
According to one embodiment, the compensation section is assigned to the connection component. The contact quality can thus be increased by adapting only the connection component or selecting a suitable connection component from a plurality of connection components for different diameters of outer conductors. According to a further embodiment, the folded-over material section is embossed at least in sections. Thus, by embossing the material section beforehand, sections can be provided with a reduced material thickness, so that the folded material section can have a material thickness that lies between the material thickness of the unfolded material section and twice the material thickness.

Gemäß einer weiteren Ausführungsform weist das Kontaktbauteil einen Kontaktabschnitt mit einem Außendurchmesser auf, und das Anschlussbauteil weist einen Innendurchmesser auf, wobei der Ausgleichsabschnitt die durch die Differenz zwischen dem Außendurchmesser des Kontaktabschnitts und dem Innendurchmesser des Anschlussbauteils gebildete Bauteildifferenz ausgleicht. Somit ist der Ausgleichsabschnitt zum Ausgleich von Durchmesserdifferenzen von zwei zu verbindenden Bauteilen ausgebildet und weist einen besonders einfachen Aufbau auf.
Gemäß einer weiteren Ausführungsform ist der Ausgleichsabschnitt aus Messing oder einer Messing enthaltenden Legierung, aus Zinnbronze oder einer Zinnbronze enthaltenden Legierung, aus Zink oder einer Zink enthaltenden Legierung, oder aus rostfreien Stahl oder einer rostfreien Stahl enthaltenden Legierung gefertigt ist. Unter Messing (CuZn) werden dabei hier Kupferlegierungen verstanden, deren Hauptbestandteile die Metalle Kupfer (Cu) und Zink (Zn) sind, während unter Zinnbronze (CuSn) Legierungen mit mindestens 60 Prozent Kupfer (Cu) verstanden werden, soweit sie nicht durch den Hauptlegierungszusatz Zink (Zn) den Messingen zuzuordnen sind, sondern als Hauptlegierungszusatz Zinn (Sn) aufweisen. Unter rostfreien Stahl (auch rostträger Stahl oder nichtrostender Stahl) versteht man hier eine Gruppe von korrosions- und säurebeständigen Stahlsorten, z.B. mit den Werkstoffnummern 1.4571 oder 1.4404.According to a further embodiment, the contact component has a contact section with an outside diameter, and the connection component has an inside diameter, the compensation section compensating for the component difference formed by the difference between the outside diameter of the contact section and the inside diameter of the connection component. The compensation section is thus designed to compensate for differences in diameter of two components to be connected and has a particularly simple construction.
According to a further embodiment, the compensation section is made from brass or an alloy containing brass, from tin bronze or an alloy containing tin bronze, from zinc or an alloy containing zinc, or from stainless steel or an alloy containing stainless steel. Brass (CuZn) is understood here to mean copper alloys, the main components of which are the metals copper (Cu) and zinc (Zn), while tin bronze (CuSn) is understood to mean alloys with at least 60 percent copper (Cu), insofar as they are not due to the main alloy additive Zinc (Zn) are assigned to the brasses, but have tin (Sn) as the main alloy additive. Stainless steel (also stainless steel or stainless steel) is a group of corrosion and acid-resistant steel grades, for example with the material numbers 1.4571 or 1.4404.

Gemäß einer weiteren Ausführungsform sind das Anschlussbauteil und der Ausgleichsabschnitt aus demselben Werkstoff gefertigt. So kann das Anschlussbauteil Ausgleichsabschnitt materialeinheitlich ausgebildet sein und ist damit besonders korrosionsbeständig.According to a further embodiment, the connection component and the compensation section are made of the same material. Thus, the connection component compensation section can be made of the same material and is therefore particularly corrosion-resistant.

Es wird zunächst auf die Fig. 1 Bezug genommen.It will first focus on the Fig. 1 Referred.

Dargestellt ist eine Außenleiteranordnung 4 für einen Koaxial-Steckverbinder 2 zur Übertragung von HF-Signalen.An outer conductor arrangement 4 for a coaxial connector 2 for the transmission of RF signals is shown.

Der Koaxial-Steckverbinder 2 ist im vorliegenden Ausführungsbeispiel als SMBA-(FAKRA)-Steckverbinder gemäß der Norm DIN 72594-1 oder USCAR-18 ausgebildet. Ferner ist der Koaxial-Steckverbinder 2 im vorliegenden Ausführungsbeispiel als Stecker ausgebildet und kann in einen entsprechenden Gegensteckverbinder (Buchse oder Kuppler) des Koaxial-Steckverbinders 2 eingesteckt werden. Abweichend vom vorliegenden Ausführungsbeispiel kann der Koaxial-Steckverbinder 2 auch als Buchse oder Kuppler ausgebildet sein.In the present exemplary embodiment, the coaxial connector 2 is designed as an SMBA (FAKRA) connector in accordance with the DIN 72594-1 or USCAR-18 standard. Furthermore, the coaxial connector 2 in the present exemplary embodiment is designed as a plug and can be inserted into a corresponding mating connector (socket or coupler) of the coaxial connector 2. In a departure from the present exemplary embodiment, the coaxial connector 2 can also be designed as a socket or coupler.

Ein derartiger Koaxial-Steckverbinder 2 weist neben der Außenleiteranordnung 4 einen Innenleiter 18 auf, um den herum die Außenleiteranordnung 4 in konzentrischer Anordnung angeordnet ist, um den Innenleiter 18 vor elektromagnetischer Störstrahlung abzuschirmen. Zwischen dem Innenleiter 18 und der Außenleiteranordnung 4 ist im vorliegenden Ausführungsbeispiel ein elektrischer Isolator 20 angeordnet.Such a coaxial connector 2 has, in addition to the outer conductor arrangement 4, an inner conductor 18, around which the outer conductor arrangement 4 is arranged in a concentric arrangement in order to shield the inner conductor 18 from electromagnetic interference radiation. In the present exemplary embodiment, an electrical insulator 20 is arranged between the inner conductor 18 and the outer conductor arrangement 4.

Die Außenleiteranordnung 4 weist im vorliegenden Ausführungsbeispiel ein Kontaktbauteil 6 und ein Anschlussbauteil 8 auf.In the present exemplary embodiment, the outer conductor arrangement 4 has a contact component 6 and a connection component 8.

Das Kontaktbauteil 6 weist im vorliegenden Ausführungsbeispiel einen Steckkopf 10 zum Einstecken in eine Buchse oder Kupplung auf, während das Anschlussbauteil 8 zum Anbinden eines Außenleiters eines Koaxialkabels (nicht dargestellt) an die Außenleiteranordnung 4 ausgebildet ist.In the present exemplary embodiment, the contact component 6 has a plug head 10 for insertion into a socket or coupling, while the connection component 8 is designed for connecting an outer conductor of a coaxial cable (not shown) to the outer conductor arrangement 4.

Das Kontaktbauteil 6 weist im vorliegenden Ausführungsbeispiel eine hohlzylinderförmige Grundform mit dem Steckkopf 10 an einem ersten Ende auf. Am anderen, dem ersten Ende gegenüberliegenden Ende des Kontaktbauteils 6 ist eine Öffnung vorgesehen, durch die der Innenleiter 18 und der Isolator 20 in das Innere der Kontaktbauteils 6 eingeführt werden können.In the present exemplary embodiment, the contact component 6 has a hollow cylindrical basic shape with the plug head 10 at a first end. At the other end of the contact component 6 opposite the first end, an opening is provided through which the inner conductor 18 and the insulator 20 can be inserted into the interior of the contact component 6.

Das Anschlussbauteil 8 weist im vorliegenden Ausführungsbeispiel in Fügerichtung zum Kontaktbauteil 6 hin einen Kontaktabschnitt 12, einen Impedanzanpassungsabschnitt 14 und einen Anschlussabschnitt 16 auf.In the present exemplary embodiment, the connection component 8 has a contact section 12, an impedance matching section 14 and a connection section 16 in the direction of joining the contact component 6.

Der Kontaktabschnitt 12 ist zum Einfügen in das Innere des Kontaktbauteils 6 und zum Verbinden mit der Innenfläche des Kontaktbauteils 6 ausgebildet, um einen Außenleiterkontakt zu bilden. Das stirnseitige Ende des Kontaktabschnitts 12 kann dabei die Funktion einer Anschlagfläche aufweisen, die mit einer Gegenanschlagfläche im Inneren des Kontaktbauteils 6 zusammenwirkt, um eine axiale Positionierung des Kontaktbauteils 6 in Bezug zum Anschlussbauteil 8 zu bewirken.The contact section 12 is designed for insertion into the interior of the contact component 6 and for connection to the inner surface of the contact component 6 in order to form an external conductor contact. The front end of the contact section 12 can have the function of a stop surface which interacts with a counter stop surface in the interior of the contact component 6 in order to bring about an axial positioning of the contact component 6 in relation to the connection component 8.

Der Impedanzanpassungsabschnitt 14 ist im vorliegenden Ausführungsbeispiel ein rohrförmiger Abschnitt des Anschlussbauteils 8, der einen Innendurchmesser und Außendurchmesser aufweist, die jeweils derart bemessen sind, dass zusammen mit dem Innenleiter 18 im vorliegenden Ausführungsbeispiel ein Wellenwiderstand von 50 Ω bereitgestellt wird. Ferner weist das Anschlussbauteil 8 im Bereich des Impedanzanpassungsabschnitts 14 eine Außendurchmessereinschnürung auf, die zusätzlich die Funktion einer Rastkante zum Bilden einer Rastverbindung aufweisen kann, mit der das Anschlussbauteil 8 mit dem Kontaktbauteil 6 verbunden wird, um so ebenfalls eine axiale Positionierung des Kontaktbauteils 6 in Bezug zum Anschlussbauteil 8 zu bewirken.In the present exemplary embodiment, the impedance matching section 14 is a tubular section of the connection component 8, which has an inner diameter and an outer diameter, which are each dimensioned such that a wave resistance of 50 Ω is provided together with the inner conductor 18 in the present exemplary embodiment. Furthermore, the connection component 8 has an outer diameter constriction in the region of the impedance matching section 14, which constriction can additionally have the function of a locking edge for forming a locking connection, with which the connection component 8 is connected to the contact component 6, so as to also axially position the contact component 6 in relation to effect connection component 8.

Der Anschlussabschnitt 16 des Anschlussbauteils 8 ist zum Anschließen eines elektrischen Außenleiters eines Koaxialkabels durch Bilden einer Crimpverbindung ausgebildet. Ferner weist der Anschlussabschnitt 16 eine Zugentlastung 22 zur mechanischen Fixierung einer Isolierung eines Außenleiters eines Koaxialkabels auf.The connection section 16 of the connection component 8 is designed to connect an electrical outer conductor of a coaxial cable by forming a crimp connection. Furthermore, the connection section 16 has a strain relief 22 for mechanically fixing an insulation of an outer conductor of a coaxial cable.

Das Kontaktbauteil 6 und das Anschlussbauteil 8 sind im vorliegenden Ausführungsbeispiel aus Messing oder einer Messing enthaltenden Legierung, aus Zinnbronze oder einer Zinnbronze enthaltenden Legierung, aus Zink oder einer Zink enthaltenden Legierung, oder aus rostfreien Stahl oder einer rostfreien Stahl enthaltenden Legierung gefertigt. Dabei sind im vorliegenden Ausführungsbeispiel das Kontaktbauteil 6 und das Anschlussbauteil 8 aus dem gleichen Material gefertigt. Somit kann die Außenleiteranordnung 4 mit dem Kontaktbauteil 6 und dem Anschlussbauteil 8 auch als materialeinheitlich bezeichnet werden. Allerdings weisen die Materialen, aus denen das Kontaktbauteil 6 und das Anschlussbauteil 8 gefertigt sind, unterschiedliche Dicken bzw. Materialstärken und Zugfestigkeiten auf. So kann das Kontaktbauteil 6 aus einem ersten Material mit einer Dicke und Zugfestigkeit gefertigt sein, das einen besonders guten elektrischen Kontakt gewährleistet, während das Anschlussbauteil 8 aus einem zweiten Material mit einer Dicke und Zugfestigkeit gefertigt ist, das einen besonders guten mechanischen Kontakt gewährleistet.In the present exemplary embodiment, the contact component 6 and the connection component 8 are manufactured from brass or an alloy containing brass, from tin bronze or an alloy containing tin bronze, from zinc or an alloy containing zinc, or from stainless steel or an alloy containing stainless steel. In the present exemplary embodiment, the contact component 6 and the connection component 8 are made of the same material. The outer conductor arrangement 4 with the contact component 6 and the connection component 8 can thus also be referred to as being of the same material. However, the materials from which the contact component 6 and the connection component 8 are made have different thicknesses or material thicknesses and tensile strengths. So can the contact component 6 is made of a first material with a thickness and tensile strength, which ensures particularly good electrical contact, while the connection component 8 is made of a second material with a thickness and tensile strength, which ensures particularly good mechanical contact.

Das Kontaktbauteil 6 und das Anschlussbauteil 8 sind im vorliegenden Ausführungsbeispiel jeweils ein Stanz-Biegebauteil. Stanz-Biegebauteile werden hergestellt, in dem sie aus z.B. einem Blech direkt vom Coil die Bauteile ausgestanzt und in ihre Endform durch Biegen gebracht werden.The contact component 6 and the connection component 8 are each a stamped and bent component in the present exemplary embodiment. Stamped and bent components are manufactured by using e.g. The components are punched out of a sheet directly from the coil and brought into their final shape by bending.

Es wird nun zusätzlich auf die Fig. 2 Bezug genommen.It is now also on the Fig. 2 Referred.

Die Fig. 2 zeigt die Außenleiteranordnung 4 für einen Koaxial-Steckverbinder 2, wobei das Kontaktbauteil 6 mit dem Anschlussbauteil 8 im vorliegenden Ausführungsbeispiel durch eine Schweißverbindung 24 stoffschlüssig verbunden ist, nachdem der Innenleiter 18 und der Isolator 20 eingesetzt wurden. Somit ist im vorliegenden Ausführungsbeispiel neben dem Kontaktbauteil 6 und dem Anschlussbauteil 8 auch die Schweißverbindung 24 materialeinheitlich ausgebildet.The Fig. 2 shows the outer conductor arrangement 4 for a coaxial connector 2, the contact component 6 being connected to the connection component 8 in the present exemplary embodiment by a welded connection 24 after the inner conductor 18 and the insulator 20 have been inserted. Thus, in the present exemplary embodiment, in addition to the contact component 6 and the connection component 8, the welded connection 24 is also made of the same material.

Es wird nun zusätzlich auf die Fig. 3 Bezug genommen.It is now also on the Fig. 3 Referred.

Die Fig. 3 zeigt die fertig montierte Außenleiteranordnung 4 zur Anbindung an einen Außenleiter eines Koaxialkabels.The Fig. 3 shows the fully assembled outer conductor arrangement 4 for connection to an outer conductor of a coaxial cable.

Es wird nun zusätzlich auf die Fig. 4 und 5 Bezug genommen, die zusammen einen Bausatz zum Bilden eines Koaxial-Steckverbinder 2 zeigen.It is now also on the Fig. 4 and 5 Reference, which together show a kit for forming a coaxial connector 2.

Während die Fig. 4 eine Außenleiteranordnung 4a für einen Koaxial-Steckverbinder 2 mit einem ersten Anschlussbauteil 8a zum Anbinden eines Koaxialkabels mit einem ersten Außenleiterdurchmesser und einem ersten Innenleiterdurchmesser zeigt, zeigt die Fig. 5 eine Außenleiteranordnung 4b für einen Koaxial-Steckverbinder 2 mit einem zweiten Anschlussbauteil 8b zum Anbinden eines Koaxialkabels mit einem zweiten Außenleiterdurchmesser, wobei die zweiten Durchmesser kleiner als die ersten Durchmesser sind.While the Fig. 4 shows an outer conductor arrangement 4a for a coaxial connector 2 with a first connection component 8a for connecting a coaxial cable with a first outer conductor diameter and a first inner conductor diameter Fig. 5 an outer conductor arrangement 4b for a coaxial connector 2 with a second connection component 8b for connecting a coaxial cable with a second outer conductor diameter, the second diameter being smaller than the first diameter.

Die Kontaktbauteile 6 der jeweiligen Außenleiteranordnungen 4a, 4b für Koaxial-Steckverbinder 2 sind jeweils baugleich ausgeführt. Jedoch sind das erste Anschlussbauteil 8a und das zweite Anschlussbauteil 8b unterschiedlich ausgeführt. So ist anhand der Fig. 4 und 5 zu erkennen, dass der erste Impedanzanpassungsabschnitt 14a der Außenleiteranordnung 4a für den ersten Innenleiterdurchmesser einen größeren Innendurchmesser und Außendurchmesser aufweist als der zweite Impedanzanpassungsabschnitt 14b der Außenleiteranordnung 4b für den zweiten Innenleiterdurchmesser. So kann erreicht werden, dass in beiden Fällen ein vorgegebener Wellenwiderstand von 50 Ω bereitgestellt wird, da durch die jeweiligen Innendurchmesser und Außendurchmesser des ersten Impedanzanpassungsabschnitt 14a und des zweiten Impedanzanpassungabschnitts 14b eine Anpassung an die Durchmesser von Innen- und Außenleiter des anzubindenden Koaxialkabels erfolgt.The contact components 6 of the respective outer conductor arrangements 4a, 4b for coaxial plug connectors 2 are each constructed identically. However, the first connection component 8a and the second connection component 8b are designed differently. So is based on the Fig. 4 and 5 to recognize that the first impedance matching section 14a of the outer conductor arrangement 4a for the first inner conductor diameter has a larger inner diameter and outer diameter than the second impedance matching section 14b of the outer conductor arrangement 4b for the second inner conductor diameter. It can thus be achieved that in both cases a predetermined wave resistance of 50 Ω is provided, since the respective inner diameter and outer diameter of the first impedance matching section 14a and the second impedance matching section 14b adapt to the diameter of the inner and outer conductors of the coaxial cable to be connected.

Ferner zeigt die Fig. 5, dass der zweite Kontaktabschnitt 12b des Anschlussbauteils 8b im vorliegenden Ausführungsbeispiel im Unterschied zum ersten Kontaktabschnitt 12a des ersten Anschlussbauteils 8a einen Ausgleichsabschnitt 26 aufweist, der im vorliegenden Ausführungsbeispiel durch einen einfach umgefalzten Rand gebildet ist. Alternativ kann der Ausgleichsabschnitt 26 auch durch ein Zusatzbauteil, wie z.B. einen Ring gebildet sein, der auf den zweiten Kontaktabschnitt 12b aufgesetzt ist.Furthermore, the Fig. 5 that the second contact section 12b of the connection component 8b in the present exemplary embodiment, in contrast to the first contact section 12a of the first connection component 8a, has a compensating section 26, which in the present exemplary embodiment is formed by a simply folded edge. Alternatively, the compensating section 26 can also be formed by an additional component, such as a ring, which is placed on the second contact section 12b.

Der Ausgleichsabschnitt 26 im vorliegenden Ausführungsbeispiel wird gebildet, in dem ein Blechabschnitt des zweiten Kontaktabschnitts 12b mit einer Falz versehen und umgebogen wird. Im vorliegenden Ausführungsbeispiel ist der Ausgleichsabschnitt 26 einfach umgefalzt. So wird im vorliegenden Ausführungsbeispiel die Materialstärke des zweiten Kontaktabschnitts 12b verdoppelt. Alternativ kann auch vorgesehen sein, vor dem Falzen den entsprechenden Materialabschnitt zu Prägen, um so seine Materialstärke zu verringern. Es kann jedoch auch eine Mehrfach-Umfalzung vorgesehen sein, um die Materialstärke entsprechend zu vervielfachen.The compensation section 26 in the present exemplary embodiment is formed by providing a sheet metal section of the second contact section 12b with a fold and bending it over. In the present exemplary embodiment, the compensation section 26 is simply folded over. In the present exemplary embodiment, the material thickness of the second contact section 12b is doubled. Alternatively, provision can also be made for embossing the corresponding material section before folding, in order to reduce its material thickness. However, multiple folds can also be provided in order to multiply the material thickness accordingly.

Durch den Ausgleichsabschnitt 26 wird erreicht, dass der zweite Kontaktabschnitt 12b des Anschlussbauteils 8b im Wesentlichen den gleichen Außendurchmesser aufweist wie der erste Kontaktabschnitt 12a des ersten Anschlussbauteils 8a, obwohl deren Innendurchmesser unterschiedlich sind. Unter "im Wesentlichen den gleichen Außendurchmesser aufweisend" wird dabei verstanden, dass der Außendurchmesser des zweiten Kontaktabschnitts 12b des zweiten Anschlussbauteils 8b im Bereich der Fertigungstoleranzen des ersten Kontaktabschnitts 12a des ersten Anschlussbauteils 8a liegt. Ohne den umgefalzten Ausgleichabschnitt 26 hingegen würde der zweite Kontaktabschnitt 12b des zweiten Anschlussbauteils 8b wegen des erforderlichen, geringeren Innendurchmessers einen reduzierten Außendurchmesser aufweisen, so dass kein ausreichend sicherer Kontakt von dem zweiten Kontaktabschnitt 12b des zweiten Anschlussbauteils 8b in dem Kontaktbauteil 6 gegeben wäre.It is achieved by the compensating section 26 that the second contact section 12b of the connection component 8b has essentially the same outer diameter as the first contact section 12a of the first connection component 8a, even though their inner diameters are different. “ Essentially the same outside diameter” is understood to mean that the outside diameter of the second contact section 12b of the second connection component 8b lies in the range of the manufacturing tolerances of the first contact section 12a of the first connection component 8a. On the other hand, without the folded-over compensating section 26, the second contact section 12b of the second connection component 8b would have a reduced outside diameter due to the required smaller inner diameter, so that there would not be a sufficiently secure contact from the second contact section 12b of the second connection component 8b in the contact component 6.

Somit erlauben der unterschiedliche erste Impedanzanpassungsabschnitt 14a und der zweite Impedanzanpassungabschitt 14b sowie der Ausgleichabschnitt 26 die Verwendung von baugleichen Kontaktbauteilen 6, wobei an dem ersten Anschlussbauteil 8a und dem zweiten Anschlussbauteil 8b jeweils Koaxialkabel mit unterschiedlichen Außendurchmessern, Außenleiterdurchmessern und Innenleiterdurchmessern angebunden werden können.Thus, the different first impedance matching section 14a and the second impedance matching section 14b and the compensating section 26 allow the use of identical contact components 6, it being possible to connect coaxial cables with different outer diameters, outer conductor diameters and inner conductor diameters to the first connection component 8a and the second connection component 8b.
