Description

Außenleiteranordnunq für einen Koaxial-Steckverbinder  Outer conductor arrangement for a coaxial connector

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 für 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 patent claim 1. Furthermore, the invention relates to a contact member and a connection component for such outer conductor arrangement, a connector for such a coaxial connector with such outer conductor arrangement, a coaxial connector with a Such 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. Coaxial connectors, such as coaxial cables, are coaxial to have the advantages of coaxial cable, namely low electromagnetic interference and radiation, and good electrical shielding and impedance equal to that of the coaxial cable connected, to reflect reflections at the interface between coaxial connectors and coaxial cables avoid. A coaxial cable, or coax cable for short, is understood here 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 Abnormal radiation. In the space between the inner conductor and the outer conductor, an insulator or dielectric is arranged.

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. 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 kleiner Durchmesser mit einem entsprechenden Anschlussbauteil ein guter elektrischer und/oder mechanischer Kontakt mit dem Kontaktbauteil nicht gegeben. Der Erfindung liegt die Aufgabe zugrunde, einen Weg aufzuzeigen, wie die Kontaktqualität unabhängig vom Durchmesser des Außenleiters verbessert werden kann. 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. 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.. 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. Coaxial connectors are designed to provide a predetermined characteristic impedance, eg of 50 Ω, in order to ensure a reflection-free transmission of RF signals. The characteristic impedance of a coaxial connector depends inter alia 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 the respective inner diameter and outer diameter of the coaxial cable adapted coaxial connector. However, this increases the production and logistics costs, for example in the manufacture of prefabricated cable harnesses, since a large number of different coaxial connectors must be kept available for different coaxial cables. Furthermore, such coaxial connector must meet different requirements, on the one hand to make a good electrical contact and on the other to ensure sufficient mechanical stability. This leads to a high production cost in the production of such coaxial connector. 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, have connection components for connecting outer conductors of a coaxial cable with different diameters matched outer dimensions. For example, a connection component for connecting an outer conductor having a first diameter has an outer diameter which is smaller than the outer diameter of a second outer conductor having a second, larger diameter. However, since the contact component is designed, for example, for connecting 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 given in the case of a connection of an outer conductor having a small diameter with a corresponding connection component. 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. This object is achieved by an outer conductor arrangement for a coaxial connector of the type mentioned above with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims. 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 member for electrical and mechanical connection to an outer conductor of a mating connector and a connection member for electrical and mechanical connection to an outer conductor of a coaxial cable, said Contact component and the connection component are electrically and mechanically connected to one another at a contact portion, wherein between the contact member and the connection component, a compensation portion for compensating for a component difference in the region of the contact portion is arranged .. This has the advantage that differences in the outer dimensions of different connection components through the compensation section be compensated for coaxial cable with different diameters and thus regardless of the inner conductor or outer conductor diameter of a coaxial cable to be connected consistent contact quality is guaranteed.

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. According to one embodiment, the compensation section is associated with the connection component. Thus, by adapting only the connection component or selecting a suitable connection component from a plurality of connection components for different diameters of outer conductors, the contact quality can be increased.

Gemäß einer weiteren Ausführungsform ist der Ausgleichsabschnitt durch einen umgefalzten Materialabschnitt des Anschlussbauteils gebildet. Somit ist das Anschlussbauteil mit dem Ausgleichsabschnitt einstückig ausgebildet und kann besonders einfach gefertigt werden. Gemäß einer weiteren Ausführungsform ist der umgefalzte Materialabschnitt zumindest abschnittsweise geprägt. So kann durch vorheriges Prägen des Materialabschnitt 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 a further embodiment, the compensation section is formed by a folded-over material section of the connection component. Thus, the connection member is formed integrally with the balancing section and can be made particularly simple. According to a further embodiment, the folded-over material section is embossed at least in sections. Thus, by prior embossing of the material section can be provided in sections with a reduced material thickness, so that the folded material portion may have a material thickness which is between the material thickness of the unfolded material portion and the double 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. According to a further embodiment, the contact component has a contact section with an outer diameter, and the connection component has an inner diameter, wherein the compensation section compensates for the component difference formed by the difference between the outer diameter of the contact section and the inner diameter of the connection component. Thus, the compensation portion is designed to compensate for differences in diameter of two components to be joined and has a particularly simple structure.

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.

Fig. 5 is a schematic exploded view of an outer conductor arrangement for a coaxial connector, consisting of the contact component shown in Fig. 4 and a connection component for connecting an electrical line with a second, smaller diameter.

Es wird zunächst auf die Fig. 1 Bezug genommen. Dargestellt ist eine Außenleiteranordnung 4 für einen Koaxial-Steckverbinder 2 zur Übertragung von HF-Signalen. Reference is first made to FIG. 1 reference. Shown is an outer conductor arrangement 4 for a coaxial connector 2 for the transmission of RF signals.

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. The coaxial connector 2 is formed in the present embodiment as SMBA (FAKRA) connector according to the standard DIN 72594-1 or USCAR-18. Further, the coaxial connector 2 is formed in the present embodiment as a plug and can be plugged into a corresponding mating connector (socket or coupler) of the coaxial connector 2. Notwithstanding the present embodiment, the coaxial connector 2 may also be formed 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. Between the inner conductor 18 and the outer conductor arrangement 4, an electrical insulator 20 is arranged in the present embodiment.

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-in head 10 for plugging 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. Das Anschlussbauteil 8 weist im vorliegenden Ausführungsbeispiel in Fügerichtung zum Kontaktbauteil 6 hin einen Kontaktabschnitt 12, einen Impedanzanpassungsabschnitt 14 und einen Anschlussabschnitt 16 auf. 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 member 6 has in the present embodiment, a hollow cylindrical basic shape with the plug head 10 at a first end. At the other, the first end opposite end of the contact member 6, an opening is provided, through which the inner conductor 18 and the insulator 20 can be inserted into the interior of the contact member 6. In the present exemplary embodiment, the connection component 8 in the joining direction toward the contact component 6 has a contact section 12, an impedance adaptation section 14 and a connection section 16. The contact portion 12 is formed for insertion into the interior of the contact member 6 and for connection with the inner surface of the contact member 6 to form an outer conductor contact. The front end of the contact portion 12 may have the function of a stop surface, which cooperates with a counter-stop surface in the interior of the contact member 6 in order to effect an axial positioning of the contact member 6 with respect to the connection member 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 Anschlussbauteils 8 im Bereich des Impedanzanpassungsabschnitts 14 eine Außendurchmessereinschnürung auf, die zusätzlich die Funktion eines 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. The impedance matching portion 14 in the present embodiment is a tubular portion of the terminal member 8 having an inner diameter and outer diameter each dimensioned so as to provide a characteristic impedance of 50 Ω together with the inner conductor 18 in the present embodiment. Furthermore, the connection component 8 has an outer diameter constriction in the region of the impedance matching section 14, which additionally may have the function of a latching edge for forming a latching connection, with which the connection component 8 is connected to the contact component 6, thus likewise an axial positioning of the contact component 6 with respect to to effect the 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 terminal portion 16 of the terminal member 8 is formed to connect an external electrical conductor of a coaxial cable by forming a crimped 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. The contact member 6 and the terminal member 8 in the present embodiment are made of brass or a brass-containing alloy, tin bronze or an alloy containing tin bronze, zinc or a zinc-containing alloy, or stainless steel or a stainless steel-containing alloy. In this case, the contact component 6 and the connection component 8 are made of the same material in the present embodiment. Thus, the outer conductor arrangement 4 with the contact component 6 and the connection component 8 can also be referred to as having 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. Thus, the contact member 6 may be made of a first material having a thickness and tensile strength, which ensures a particularly good electrical contact, while the connection member 8 is made of a second material having a thickness and tensile strength, which ensures a 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. In the present exemplary embodiment, the contact component 6 and the connection component 8 are each a stamped and bent component. Punching and bending components are manufactured in that they are made of e.g. a sheet directly from the coil punched out the components and are brought into their final shape by bending.

Es wird nun zusätzlich auf die Fig. 2 Bezug genommen. Reference is now additionally made to FIG. 2.

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. Es wird nun zusätzlich auf die Fig. 3 Bezug genommen. FIG. 2 shows the outer conductor arrangement 4 for a coaxial connector 2, wherein the contact component 6 is materially 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 of the same material. Reference is now additionally made to FIG. 3.

Die Fig. 3 zeigt die fertig montierte Außenleiteranordnung 4 zur Anbindung an einen Außenleiter eines Koaxialkabels. Es wird nun zusätzlich auf die Fig. 4 und 5 Bezug genommen, die zusammen einen Bausatz zum Bilden eines Koaxial-Steckverbinder 2 zeigen. 3 shows the fully assembled outer conductor arrangement 4 for connection to an outer conductor of a coaxial cable. Reference is now additionally made to Figs. 4 and 5, 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 Fig. 4 shows an outer conductor arrangement 4a for a coaxial connector 2 with a first terminal member 8a for connecting a coaxial cable with a 5 shows 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 diameters being smaller than the first diameters.

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-in connectors 2 are of identical construction. However, the first terminal member 8a and the second terminal member 8b are made different. 4 and 5, 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. Thus, it can be achieved that in both cases, a predetermined characteristic impedance of 50 Ω is provided, as by the respective inner diameter and outer diameter of the first impedance matching portion 14a and the second impedance matching portion 14b to adapt to the diameter of the inner and outer conductor 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, FIG. 5 shows that the second contact section 12b of the connection component 8b in the present exemplary embodiment, unlike the first contact section 12a of the first connection component 8a, has a compensation section 26, which in the present exemplary embodiment is formed by a single folded edge. Alternatively, the balancing section 26 may also be provided by an accessory such as e.g. a ring formed on the second contact portion 12 b is formed.

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 equalizing portion 26 in the present embodiment is formed by crimping and bending a sheet portion of the second contact portion 12b. In the present embodiment, the compensation portion 26 is simply folded over. Thus, in the present embodiment, the material thickness of the second contact portion 12b is doubled. Alternatively, it can also be provided to emboss the corresponding material section before folding in order to increase its material thickness reduce. However, it can also be provided a multiple Umfalzung 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. By the balancing portion 26, it is achieved that the second contact portion 12b of the terminal member 8b has substantially the same outer diameter as the first contact portion 12a of the first terminal member 8a, although their inner diameters are different. In this context, "substantially the same outside diameter" is understood to mean that the outside diameter of the second contact section 12b of the second connection component 8b is within the range of the manufacturing tolerances of the first contact section 12a of the first connection component 8. Without the folded compensating section 26, however, the second contact section 12b of FIG second terminal member 8b have a reduced outer diameter because of the required, smaller inner diameter, so that no sufficiently secure contact would be given by the second contact portion 12b of the second terminal member 8b in the contact member 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 balancing section 26 allow the use of identical contact components 6, wherein coaxial cables having different outer diameters, outer conductor diameters and inner conductor diameters can be connected to the first terminal component 8a and the second terminal component 8b, respectively.
