Description

Die Erfindung betrifft ein konfektioniertes Kabel, das einen Adapter aufweist.The invention relates to a ready-made cable that has an adapter.

Datennetze im Automobil übertragen heutzutage Daten für unterschiedliche Anwendungen, beispielsweise Sensordaten, Daten der Unterhaltungselektronik, in einer vergleichsweise sehr hohen Datenrate über 1 GB/s. Hierfür haben sich sogenannte HSD-Kabel (high speed data; deutsch: Daten in einer hohen Übertragungsrate) etabliert. Derartige HSD-Kabel weisen für die parallele Übertragung von zwei differenziellen Signalen zwei Paare von Datenleitungen auf, die in einer sogenannten Stern-Vierer-Anordnung zueinander überkreuzt angeordnet sind und entlang der Datenleitung spiralförmig verseilt sind.Data networks in automobiles nowadays transmit data for different applications, for example sensor data, data from entertainment electronics, at a comparatively very high data rate of more than 1 GB/s. So-called HSD cables (high speed data; German: data at a high transmission rate) have been established for this purpose. For the parallel transmission of two differential signals, HSD cables of this type have two pairs of data lines which are arranged crossed over one another in a so-called star-quad arrangement and are stranded spirally along the data line.

Während die Verseilung der Stern-Vierer-Anordnung eine niedrigere Packungsdichte bewirkt, ermöglicht die Stern-Vierer-Anordnung zumindest im niedrigeren bis mittelgroßen Frequenzbereich ein geringeres Übersprechen zwischen den beiden Paaren von Datenleitungen. Im höheren Frequenzbereich verschlechtert sich das Übersprechen zwischen den einzelnen Paaren von Datenleitungen deutlich.While the stranding of the star-quad arrangement results in a lower packing density, the star-quad arrangement enables less crosstalk between the two pairs of data lines, at least in the lower to medium-high frequency range. In the higher frequency range, the crosstalk between the individual pairs of data lines deteriorates significantly.

Für den höheren Frequenzbereich werden deshalb verstärkt Kabel eingesetzt, in denen jeweils zwei geschirmte und parallel verlaufende, d.h. nicht-überkreuzte, Paare von Datenleitungen verlaufen. Durch die Schirmung jedes einzelnen Paares von Datenleitungen wird das Übersprechen zwischen den einzelnen Paaren verbessert.Cables are therefore increasingly used for the higher frequency range, in each of which two shielded pairs of data lines run parallel, i.e. do not cross over. Shielding each pair of data lines improves crosstalk between pairs.

Aufgrund der weitaus höheren Verbreitung von Kabeln mit Stern-Vierer-Anordnung gegenüber Kabeln mit parallelen und jeweils geschirmten Paaren von Datenleitungen existieren im Automobilbau viele Steckverbinder mit Anbindung beispielsweise an eine Leiterplatte einer HF-Elektronik, die auf eine Stern-Vierer-Anordnung der Datenleitungen ausgerichtet sind. Die Anbindung von konfektionierten Kabeln mit parallelen und jeweils geschirmten Paaren von Datenleitungen an bestehende Leiterplatten von HF-Elektroniken mit einem Steckverbinder in Stern-Vierer-Anordnung der Datenleitungen ist deshalb nicht möglich und verschlechtert somit nachteilig den universellen Einsatz von derartigen Kabeln.Due to the far greater spread of cables with a star-quad arrangement compared to cables with parallel and shielded pairs of data lines, there are Automobile many connectors with connection, for example, to a printed circuit board of HF electronics, which are aligned to a star-quad arrangement of the data lines. The connection of prefabricated cables with parallel and respectively shielded pairs of data lines to existing printed circuit boards of HF electronics with a connector in a star-quad arrangement of the data lines is therefore not possible and thus adversely affects the universal use of such cables.

Die WO 2012/087956 A2 und die US2010/0183141 A1 offenbaren jeweils zur Reduzierung des Übersprechens zwischen zwei differentiellen Signalleitungs-Paaren ein Signalleitungs-Paar mit überkreuzt zueinander angeordneten Signalleitungen und ein Signalleitungs-Paar mit parallel zueinander angeordneten Signalleitungen.the WO 2012/087956 A2 and the US2010/0183141 A1 disclose in each case a signal line pair with signal lines arranged crossed over one another and a signal line pair with signal lines arranged parallel to one another in order to reduce the crosstalk between two differential signal line pairs.

Die EP 3 163 688 A1 offenbart einen Adapter zur Verbindung zwischen zwei Signalleitungs-Paaren mit jeweils überkreuzt zueinander angeordneten Signalleitungen und zwei Signalleitungs-Paaren mit jeweils parallel zueinander angeordneten Signalleitungen.the EP 3 163 688 A1 discloses an adapter for the connection between two pairs of signal lines each having signal lines arranged crossed over one another and two pairs of signal lines each having signal lines arranged parallel to one another.

Die US 2013/0333913 A1 beschreibt ein Kabel mit mehreren parallel angeordneten differentiellen Signalleitungs-Paaren.the US 2013/0333913 A1 describes a cable with a plurality of differential signal line pairs arranged in parallel.

Aufgabe der Erfindung ist es deshalb, eine Vorrichtung zu schaffen, mit der Kabel mit parallelen und jeweils geschirmten Paaren von Datenleitungen an Steckverbinder in Stern-Vierer-Anordnung der Datenleitungen ankoppelbar sind.The object of the invention is therefore to create a device with which cables with parallel and respectively shielded pairs of data lines can be coupled to plug connectors in a star-quad arrangement of the data lines.

Die Aufgabe wird durch ein erfindungsgemäßes Kabel mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte technische Erweiterungen können den jeweils abhängigen Patentansprüchen entnommen werden.The object is achieved by a cable according to the invention with the features of claim 1. beneficial technical extensions can be found in the respective dependent patent claims.

Die beiden geschirmten Paare von Innenleitern des Kabels werden nicht nur an die beiden parallelen ersten Paare von Kontaktbereichen im ersten Anschlussbereich geführt, werden bis zu den Kontaktbereichen des zweiten Anschlussbereiches des Adapters geführt. Somit sind die ersten und zweiten Kontaktbereiche des einen ersten Paares von Kontaktbereichen über jeweils einen unterschiedlichen Innenleiter des einen Paares von Innenleitern des Kabels mit dem dritten bzw. vierten Kontaktbereichs des einen zweiten Paares von Kontaktbereichen elektrisch verbunden, während die ersten und zweiten Kontaktbereiche des anderen ersten Paares von Kontaktbereichen über jeweils einen unterschiedlichen Innenleiter des anderen Paares von Innenleitern mit dem dritten bzw. vierten Kontaktbereich des zweiten Paares von Kontaktbereichen elektrisch verbunden sind.The two shielded pairs of inner conductors of the cable are not only routed to the two parallel first pairs of contact areas in the first connection area, are routed to the contact areas of the second connection area of the adapter. Thus, the first and second contact areas of the first pair of contact areas are each electrically connected via a different inner conductor of the one pair of inner conductors of the cable to the third and fourth contact area of the one second pair of contact areas, while the first and second contact areas of the other first Pair of contact areas are electrically connected via a different inner conductor of the other pair of inner conductors with the third and fourth contact area of the second pair of contact areas.

Bevorzugte technische Erweiterungen sind sowohl für den einzelnen Adapter als auch für das Kabel mit integriertem Adapter realisiert:
Um das induktive Uberkoppeln zwischen den beiden zueinander überkreuzt angeordneten Innenleitern im Bereich der Uberkreuzung zu minimieren, sind die überkreuzt angeordneten Innenleiter jeweils in einem Winkel zwischen 85° und 95° zueinander orientiert. Bevorzugt sind die überkreuzt angeordneten Innenleiter jeweils senkrecht zueinander orientiert. Hierzu werden die beiden überkreuzt zueinander angeordneten Innenleiter bevorzugt jeweils im Bereich des ersten Anschlussbereiches und des zweiten Anschlussbereiches parallel zueinander und parallel zu den beiden parallel geführten Innenleitern geführt, um auf diese Weise eine möglichst orthogonale Orientierung der beiden überkreuzt zueinander angeordneten Innenleiter im Bereich der Überkreuzung zu realisieren.Preferred technical extensions have been implemented both for the individual adapter and for the cable with an integrated adapter:
In order to minimize the inductive cross-coupling between the two inner conductors arranged crossed over one another in the region of the crossing, the inner conductors arranged crossed over are each oriented at an angle of between 85° and 95° to one another. The crossed-over inner conductors are preferably each oriented perpendicular to one another. For this purpose, the two inner conductors arranged crossed over one another are preferably routed parallel to one another and parallel to the two parallel inner conductors in the area of the first connection area and the second connection area, in order in this way to achieve as orthogonal an orientation as possible of the two crossed inner conductors in the area of the crossing.

Das kapazitive Überkoppeln zwischen den beiden zueinander überkreuzt angeordneten Innenleitern im Bereich der Überkreuzung wird dadurch minimiert, dass der Abstand zwischen den beiden zueinander überkreuzt angeordneten Innenleitern im Überkreuzungsbereich maximiert wird:
In einer ersten Variante für eine Minimierung des kapazitiven Uberkoppelns sind die beiden überkreuzt zueinander angeordneten Innenleiter bevorzugt zueinander konvex gekrümmt. Somit weisen sie in der Mitte zwischen dem ersten Anschlussbereich und dem zweiten Anschlussbereich, d.h. im Bereich der Überkreuzung, ihren größten Abstand zueinander auf.The capacitive overcoupling between the two crossed inner conductors in the crossing area is minimized by maximizing the distance between the two crossed inner conductors in the crossing area:
In a first variant for minimizing capacitive overcoupling, the two inner conductors which are arranged crossed over one another are preferably curved in a convex manner in relation to one another. They are therefore at their greatest distance from one another in the middle between the first connection area and the second connection area, ie in the area of the crossing.

In der zweiten Variante wird die Minimierung des kapazitiven Uberkoppelns zwischen den beiden überkreuzt zueinander angeordneten Innenleitern dadurch realisiert, dass in jeweils gegenüberliegenden Bereichen der beiden überkreuzt zueinander angeordneten Innenleiter im Bereich der Überkreuzung bevorzugt jeweils Material abgetragen ist und somit der Abstand zwischen den beiden überkreuzt zueinander angeordneten Innenleitern vergrößert ist.In the second variant, the minimization of the capacitive overcoupling between the two inner conductors arranged crossed over one another is realized in that in opposite areas of the two inner conductors arranged crossed over one another, material is preferably removed in the area of the crossing and thus the distance between the two arranged crossed over one another Inner conductors is enlarged.

In einer dritten Variante für eine Minimierung des kapazitiven Überkoppelns sind die beiden überkreuzt zueinander angeordneten Innenleiter bevorzugt jeweils asymmetrisch versetzt zur zugehörigen Verbindungsgerade zwischen den beiden Kontaktbereichen des ersten und zweiten Anschlussbereiches geführt. Die beiden überkreuzt zueinander angeordneten Innenleiter weisen dann ihren größtmöglichen Abstand im Hinblick auf ein minimiertes kapazitives Überkoppeln auf, wenn die beiden asymmetrischen Versetzungen jeweils um 180° zueinander phasenversetzt sind. Zusätzlich weist derjenige Innenleiter der beiden zueinander überkreuzt angeordneten Innenleiter in allen drei Varianten bevorzugt einen veränderten Durchmesser als der jeweils andere Innenleiter der beiden zueinander überkreuzt angeordneten Innenleiter auf, der räumlich näher an der Umfangsfläche des zylindrischen Adapters und damit an der den Adapter umschließenden Masseschirmung geführt ist.In a third variant for minimizing the capacitive overcoupling, the two inner conductors arranged crossed over one another are preferably each routed asymmetrically offset to the associated connecting straight line between the two contact areas of the first and second connection area. The two inner conductors arranged crossed over one another then have their greatest possible distance with regard to minimized capacitive cross-coupling when the two asymmetrical offsets are each 180° out of phase with one another. In addition, that inner conductor of the two crossed inner conductors in all three variants preferably has a different diameter than the other inner conductor of the two crossed inner conductors that is spatially closer to the peripheral surface of the cylindrical adapter and thus to the ground shielding surrounding the adapter .

Bevorzugt weist derjenige Innenleiter der beiden zueinander überkreuzt angeordneten Innenleiter in allen drei Varianten bevorzugt einen geringeren Durchmesser als der jeweils andere Innenleiter der beiden zueinander überkreuzt angeordneten Innenleiter auf, der räumlich näher an der Umfangsfläche des zylindrischen Adapters und damit an der den Adapter umschließenden Masseschirmung geführt ist.In all three variants, that inner conductor of the two inner conductors arranged crossed over one another preferably has a smaller diameter than the respective other inner conductor of the two inner conductors arranged crossed over one another, which is guided spatially closer to the peripheral surface of the cylindrical adapter and thus to the ground shielding surrounding the adapter .

Die Änderung, bevorzugt die Reduzierung des Durchmessers des näher an der Masseschirmung geführten Innenleiters der beiden zueinander überkreuzt angeordneten Innenleiter bewirkt vorteilhaft einen optimalen Wert für die kapazitive Komponente der Impedanz des Adapters zwischen ersten und zweiten Anschlussbereich.The change, preferably the reduction, of the diameter of the inner conductor, which is routed closer to the ground shielding, of the two inner conductors arranged crossed over one another advantageously brings about an optimal value for the capacitive component of the impedance of the adapter between the first and second connection area.

Da die beiden zueinander überkreuzt angeordneten Innenleiter eine größere Länge gegenüber den beiden parallel zueinander angeordneten Innenleitern aufweisen, sind die Laufzeiten der HF-Signale in diesen Innenleitern jeweils unterschiedlich. Die Signalanteile eines differenziellen Signals sind nach Durchlaufen der Innenleiter nicht mehr 180° phasenversetzt, sondern können aufgrund der unterschiedlichen Laufzeiten in den beiden Innenleitern eine anderen Phasenversatz aufweisen und stellen somit auch kein exaktes differenzielles Signal mehr dar.Since the two inner conductors arranged crossed over one another are longer than the two inner conductors arranged parallel to one another, the propagation times of the HF signals in these inner conductors are different in each case. The signal components of a differential signal are no longer phase-shifted by 180° after passing through the inner conductor, but can have a different phase shift due to the different propagation times in the two inner conductors and therefore no longer represent an exact differential signal.

Ein Ausgleich der unterschiedlichen Laufzeiten in den unterschiedlich angeordneten Innenleitern erfolgt durch eine unterschiedliche Ausbreitungsgeschwindigkeit der Signalanteile des differenziellen HF-Signals. Gemäß der Erfindung sind die zueinander überkreuzt angeordneten Innenleiter jeweils von einem Material mit einer niedrigeren Permittivität umgeben als die zueinander parallel angeordneten Innenleiter. Das Material mit der niedrigeren Permittivität bewirkt eine höhere Ausbreitungsgeschwindigkeit, mit der die größere Länge der zueinander überkreuzt angeordneten Innenleiter kompensiert wird. Auf diese Weise ist vorteilhaft gewährleistet, dass an beiden Anschlussbereichen des Adapters ein differenzielles HF-Signal mit zwei Signalanteilen auftreten, die jeweils einen Phasenversatz von 180° zueinander aufweisen.The different propagation times in the differently arranged inner conductors are compensated for by a different propagation speed of the signal components of the differential HF signal. According to the invention, the inner conductors arranged crossed over one another are each surrounded by a material with a lower permittivity than the inner conductors arranged parallel to one another. The material with the lower permittivity results in a higher propagation speed, with which the greater length of the inner conductors, which are arranged crossed over one another, is compensated for. In this way, it is advantageously ensured that a differential HF signal with two signal components occurs at both connection areas of the adapter, each of which has a phase offset of 180° with respect to one another.

Im Folgenden wird eine erste Ausführungsform eines Adapters 1 anhand der Figuren 1A, 1B und 1C im Detail erläutert:
Der Adapter 1 weist einen hinsichtlich einer Längsachse 2 rotationssymmetrischen Grundkörper auf, der bevorzugt hohlzylindrisch ausgeführt ist. Der bevorzugt hohlzylindrische Adapter 1 besitzt im Bereich seiner beiden Stirnseiten jeweils eine Stirnfläche. Der Adapter 1 ist bevorzugt als Kunststoff-Spritzgussteil beispielsweise aus Polyethylen oder Polypropylen gefertigt.In the following, a first embodiment of an adapter 1 based on the Figures 1A, 1B and 1C explained in detail:
The adapter 1 has a base body which is rotationally symmetrical with respect to a longitudinal axis 2 and is preferably designed as a hollow cylinder. The preferably hollow-cylindrical adapter 1 has an end face in the region of each of its two end faces. The adapter 1 is preferably made as a plastic injection molded part, for example made of polyethylene or polypropylene.

Die in Fig. 1A rechtsseitig dargestellte Stirnfläche stellt einen ersten Anschlussbereich 3 dar, während die linksseitig dargestellte Stirnfläche einen zweiten Anschlussbereich 4 bildet. Sowohl der erste Anschlussbereich 3 als auch der zweite Anschlussbereich 4 weist jeweils eine der Anzahl von differenziellen Signalen entsprechende Anzahl von Paaren von Kontaktbereichen auf. Bevorzugt sind an beiden Anschlussbereichen zwei Paare von Kontaktbereichen entsprechend der Anzahl von in einem HSD-Kabel übertragenen differenziellen Signalen vorgesehen. Die einzelnen Kontaktbereiche umfassen jeweils den gesamten Bereich der zugehörigen, in Fig. 1A jeweils dargestellten Bohrungen bzw. Ausnehmungen im ersten Anschlussbereich 3 bzw. im zweiten Anschlussbereich 4 des Adapters 1.In the Figure 1A The end face shown on the right represents a first connection area 3 , while the end face shown on the left forms a second connection area 4 . Both the first connection area 3 and the second connection area 4 each have a number of pairs of contact areas that corresponds to the number of differential signals. Two pairs of contact areas corresponding to the number of differential signals transmitted in an HSD cable are preferably provided on both connection areas. The individual contact areas each cover the entire area of the associated in Figure 1A respectively illustrated bores or recesses in the first connection area 3 or in the second connection area 4 of the adapter 1.

Gemäß Fig. 1C weist der erste Anschlussbereich 3 zwei erste Paare 51 und 52 von Kontaktbereichen mit jeweils einem ersten Kontaktbereich 611 und 612 und einem zweiten Kontaktbereich 621 und 622 auf. Die beiden ersten Paare 51 und 52 von Kontaktbereichen des ersten Anschlussbereiches 3 sind zueinander parallel angeordnet.According to Figure 1C For example, the first connection area 3 has two first pairs 5 1 and 5 2 of contact areas, each with a first contact area 6 11 and 6 12 and a second contact area 6 21 and 6 22 . The two first pairs 5 1 and 5 2 of contact areas of the first connection area 3 are arranged parallel to one another.

Im ersten Kontaktbereich 611 des ersten Paares 51 von Kontaktbereichen im ersten Anschlussbereich 3 ist ein Innenleiter des Kabels mit einer ersten Verbindungsleitung 7 beispielsweise über eine Lötung elektrisch verbunden. Im zweiten Kontaktbereich 621 des ersten Paares 51 von Kontaktbereichen im ersten Anschlussbereich 3 ist ein weiterer Innenleiter desselben Paares von miteinander geschirmten Innenleitern des Kabels mit einer zweiten Verbindungsleitung 8 elektrisch verbunden. Die mit demselben Paar von miteinander geschirmten Innenleitern des Kabels elektrisch verbundene erste Verbindungsleitung 7 und zweite Verbindungsleitung 8 ist durch eine gemeinsame Schraffur gekennzeichnet. Die erste Verbindungsleitung 7 ist zu einem dritten Kontaktbereich 911 eines zweiten Paares 101 von Kontaktbereichen im zweiten Anschlussbereich 4 geführt, während die zweite Verbindungsleitung 8 zu einem vierten Kontaktbereich 921 desselben zweiten Paares 101 von Kontaktbereichen im zweiten Anschlussbereich 4 geführt ist.In the first contact area 6 11 of the first pair 5 1 of contact areas in the first connection area 3, an inner conductor of the cable is electrically connected to a first connecting line 7, for example via soldering. In the second contact area 6 21 of the first pair 5 1 of contact areas in the first connection area 3 , another inner conductor of the same pair of inner conductors of the cable that are shielded from one another is electrically connected to a second connecting line 8 . The first connecting line 7 and the second connecting line 8, which are electrically connected to the same pair of shielded inner conductors of the cable, are identified by common hatching. The first connecting line 7 is led to a third contact area 9 11 of a second pair 10 1 of contact areas in the second connection area 4, while the second connecting line 8 is led to a fourth contact area 9 21 of the same second pair 10 1 of contact areas in the second connection area 4.

Im ersten Kontaktbereich 612 eines weiteren ersten Paares 52 von Kontaktbereichen im ersten Anschlussbereich 3 ist ein Innenleiter eines weiteren geschirmten Paares von Innenleitern des Kabels mit einer dritten Verbindungsleitung 11 elektrisch verbunden. Im zweiten Kontaktbereich 622 des weiteren Paares 52 von Kontaktbereichen im ersten Anschlussbereich 3 ist ein anderer Innenleiter dieses weiteren geschirmten Paares von Innenleitern des Kabels mit einer vierten Verbindungsleitung 12 elektrisch verbunden. Die dritte Verbindungsleitung 11 und die vierte Verbindungsleitung 12, die mit demselben Paar von miteinander geschirmten Innenleitern des Kabels elektrisch verbunden sind, sind beide unschraffiert dargestellt. Die dritte Verbindungsleitung 11 ist zu einem dritten Kontaktbereich 912 eines weiteren zweiten Paares 102 von Kontaktbereichen im zweiten Anschlussbereich 4 geführt, während die vierte Verbindungsleitung 12 zu einem vierten Kontaktbereich 922 desselben zweiten Paares 102 von Kontaktbereichen im zweiten Anschlussbereich 4 geführt ist.In the first contact area 6 12 of a further first pair 5 2 of contact areas in the first connection area 3 , an inner conductor of a further shielded pair of inner conductors of the cable is electrically connected to a third connecting line 11 . In the second contact area 6 22 further Pair 5 2 of contact areas in the first connection area 3 is another inner conductor of this further shielded pair of inner conductors of the cable with a fourth connecting line 12 is electrically connected. The third connection line 11 and the fourth connection line 12, which are electrically connected to the same pair of mutually shielded inner conductors of the cable, are both shown without hatching. The third connecting line 11 is led to a third contact area 9 12 of a further second pair 10 2 of contact areas in the second connection area 4, while the fourth connecting line 12 is led to a fourth contact area 9 22 of the same second pair 10 2 of contact areas in the second connection area 4.

Wie in den Figuren 1B und 1C dargestellt ist, stellen die erste, zweite, dritte und vierte Verbindungsleitung 7, 8, 11 und 12 jeweils ein Bündel von leitenden Litzen bevorzugt aus Kupfer mit einer Ummantelung aus einem nicht-leitenden Kunststoff dar.As in the Figures 1B and 1C is shown, the first, second, third and fourth connecting lines 7, 8, 11 and 12 each represent a bundle of conductive strands, preferably made of copper with a sheath made of a non-conductive plastic.

Die erste, zweite, dritte und vierte Verbindungsleitung 7, 8, 11 und 12 sind im Bereich der ersten und zweiten Paare 51 und 52 bzw. 101 und 102 von Kontaktbereichen entweder bis zur äußeren Begrenzung oder bis zur inneren Begrenzung der zum jeweiligen Kontaktbereich gehörigen Bohrung bzw. Ausnehmung geführt. Alternativ können die erste, zweite, dritte und vierte Verbindungsleitung 7, 8, 11 und 12 auch innerhalb der zum jeweiligen Kontaktbereich gehörigen Bohrung bzw. Ausnehmung enden.The first, second, third and fourth connecting lines 7, 8, 11 and 12 are in the area of the first and second pairs 5 1 and 5 2 or 10 1 and 10 2 of contact areas either up to the outer boundary or to the inner boundary of the respective contact area associated hole or recess out. Alternatively, the first, second, third and fourth connecting lines 7, 8, 11 and 12 can also end within the bore or recess associated with the respective contact area.

Aus Fig. 1A ist zu erkennen, dass die zweite Verbindungsleitung 8 und die vierte Verbindungsleitung 12 innerhalb des Adapters 1 jeweils parallel zueinander entlang der Längsachse 2 angeordnet sind, während die erste Verbindungsleitung 7 und die dritte Verbindungsleitung 11 jeweils zueinander überkreuzt angeordnet sind.Out of Figure 1A It can be seen that the second connecting line 8 and the fourth connecting line 12 are each arranged parallel to one another within the adapter 1 along the longitudinal axis 2, while the first connecting line 7 and the third connection line 11 are respectively arranged to cross each other.

Die zweite und die vierte Verbindungsleitung 8 und 12, die jeweils parallel zueinander angeordnet sind, weisen jeweils einen derartigen Abstand zueinander und zu einer in Fig. 1A nicht dargestellten, an der Umfangfläche des Adapters 1 anliegenden Masseschirmung auf, so dass das induktive und kapazitive Überkoppeln zwischen zweiter und vierter Verbindungsleitung 8 und 12 insgesamt minimiert ist. Zur Minimierung des induktiven und kapazitiven Überkoppelns zwischen der ersten und dritten Verbindungsleitung 7 und 11, die zueinander überkreuzt angeordnet sind, werden bevorzugt folgende technische Maßnahmen durchgeführt:
In einer zweiten Ausführungsform 1' eines Adapters gemäß Fig. 2 werden hierzu die erste und dritte Verbindungsleitung 7' und 11' so zueinander überkreuzt, dass sie im Überkreuzungsbereich in einem Winkel zwischen 85° und 95° zueinander orientiert sind bzw. bevorzugt orthogonal, d.h. in einem Winkel von 90°, zueinander orientiert sind. Auf diese Weise wird ein induktives Überkoppeln weitestgehend vermieden. Hierzu sind die erste und zweite Verbindungsleitung 7' und 11' im Bereich der zugehörigen Kontaktbereiche, d.h. im Bereich des ersten Kontaktbereiches 611 bzw. des ersten Kontaktbereiches 612 der beiden ersten Paare 51 und 52 von Kontaktbereichen im ersten Anschlussbereich 3 und im Bereich des ersten Kontaktbereichs 911 und des ersten Kontaktbereichs 912 der beiden zweiten Paare 101 und 102 von Kontaktbereichen im zweiten Anschlussbereich 4, über eine größere Strecke parallel zueinander geführt.The second and fourth connecting lines 8 and 12, which are each arranged parallel to one another, are each at such a distance from one another and from an in Figure 1A not shown, applied to the peripheral surface of the adapter 1 ground shielding, so that the inductive and capacitive overcoupling between the second and fourth connecting lines 8 and 12 is minimized overall. The following technical measures are preferably implemented to minimize the inductive and capacitive overcoupling between the first and third connecting lines 7 and 11, which are arranged crossed over one another:
In a second embodiment 1 'of an adapter according to 2 For this purpose, the first and third connecting lines 7' and 11' cross each other in such a way that they are oriented at an angle of between 85° and 95° to one another in the crossing area or are preferably oriented orthogonally, ie at an angle of 90°, to one another. In this way, inductive overcoupling is largely avoided. For this purpose, the first and second connecting lines 7' and 11' are in the area of the associated contact areas, i.e. in the area of the first contact area 6 11 or the first contact area 6 12 of the two first pairs 5 1 and 5 2 of contact areas in the first connection area 3 and in the Area of the first contact area 9 11 and the first contact area 9 12 of the two second pairs 10 1 and 10 2 of contact areas in the second connection area 4, out over a longer distance parallel to each other.

Eine erste Variante zur Minimierung des kapazitiven Überkoppelns im Überkreuzungsbereich zwischen der ersten und zweiten Verbindungsleitung, die zueinander überkreuzt angeordnet sind, geht aus den Figuren 3A, 3B und 3C hervor:
Wie aus den Figuren 3B und 3C hervorgeht, ist die Darstellung in Fig. 3A entlang der Längsachse 2 des Adapters um 90° gegenüber der Darstellung in den vorherigen Figuren 1A und 2 gedreht.A first variant for minimizing the capacitive cross-coupling in the crossover area between the first and second Connecting line, which are arranged crossed to each other, goes from the Figures 3A, 3B and 3C out:
How from the Figures 3B and 3C shows, the representation is in Figure 3A along the longitudinal axis 2 of the adapter by 90° compared to the representation in the previous ones Figures 1A and 2 turned.

Zu erkennen ist, dass die erste und dritte Verbindungsleitung 7" und 11", die zueinander überkreuzt angeordnet sind, in der dritten Ausführungsform 1" des Adapters konvex zueinander gekrümmt sind und somit im Bereich der Überkreuzung einen vergrößerten Abstand zueinander aufweisen. Durch den vergrößerten Abstand im Überkreuzungsbereich wird das kapazitive Überkoppeln zwischen erster und dritter Verbindungsleitung 7" und 11" minimiert.It can be seen that the first and third connecting lines 7" and 11", which are arranged to cross one another, are curved convexly to one another in the third embodiment 1" of the adapter and are therefore at an increased distance from one another in the area of the crossing. Due to the increased distance in the crossover area, the capacitive overcoupling between the first and third connecting lines 7" and 11" is minimized.

Die erste Verbindungsleitung 7", die näher an der Umfangsfläche des im Wesentlichen zylindrischen Adapters 1" und damit näher an der in Fig. 3A nicht dargestellten Masseschirmung positioniert ist, weist, wie aus Fig. 3A zu erkennen ist, einen geänderten Durchmesser, bevorzugt einen geringeren Durchmesser, als die dritte Verbindungsleitung 11" auf, die weiter entfernt von der Umfangsfläche des Adapters 1" und damit von der Masseschirmung positioniert ist. Dieser bevorzugt geringere Durchmesser der ersten Verbindungsleitung 7" bewirkt einen optimalen Wert für die kapazitive Komponente der Impedanz zwischen ersten Anschlussbereich 3 und zweiten Anschlussbereich 4 des Adapters 1".The first connecting line 7", which is closer to the peripheral surface of the essentially cylindrical adapter 1" and thus closer to the in Figure 3A non-illustrated ground shield is positioned, shows how Figure 3A as can be seen, has a different diameter, preferably a smaller diameter, than the third connecting line 11", which is positioned further away from the peripheral surface of the adapter 1" and thus from the ground shielding. This preferably smaller diameter of the first connecting line 7" results in an optimum value for the capacitive component of the impedance between the first connection area 3 and the second connection area 4 of the adapter 1".

Eine zweite Variante, mit der das kapazitive Überkoppeln im Überkreuzungsbereich zwischen der ersten und zweiten Verbindungsleitung, die zueinander überkreuzt angeordnet sind, minimiert werden kann, ist in den Figuren 4A, 4B und 4C dargestellt:
In der vierten Ausführungsform 1‴ des Adapters wird ein vergrößerter Abstand zwischen erster und dritter Verbindungsleitung 7‴ und 11‴, die jeweils zueinander überkreuzt angeordnet sind, dadurch realisiert, dass sie jeweils asymmetrisch versetzt zu einer Verbindungsgerade zwischen den zugehörigen Kontaktbereichen und um einen Winkel von 180° versetzt zueinander geführt sind. Die erste Verbindungsleitung 7‴ wird somit im Bereich des ersten Kontaktbereichs 611 eines ersten Paares 51 von Kontaktbereichen im ersten Anschlussbereich 3 und im Bereich des dritten Kontaktbereich 911 eines zweiten Paares 101 von Kontaktbereichen im zweiten Anschlussbereich 4 asymmetrisch verlegt. Die zweite Verbindungsleitung 11‴ wird im Bereich des zweiten Kontaktbereichs 612 eines ersten Paares 52 von Kontaktbereichen im ersten Anschlussbereich 3 und im Bereich des zweiten Kontaktbereichs 922 eines zweiten Paares 102 von Kontaktbereichen im zweiten Anschlussbereich 4 asymmetrisch verlegt.A second variant, with which the capacitive overcoupling in the crossover area between the first and second connecting lines, which are arranged crossed over one another, can be minimized is Figures 4A, 4B and 4C shown:
In the fourth embodiment 1‴ of the adapter, an increased distance between the first and third connecting lines 7‴ and 11‴, which are each arranged crossed over one another, is realized in that they are each offset asymmetrically to a connecting straight line between the associated contact areas and at an angle of 180° offset from one another. The first connecting line 7‴ is thus laid asymmetrically in the area of the first contact area 6 11 of a first pair 5 1 of contact areas in the first connection area 3 and in the area of the third contact area 9 11 of a second pair 10 1 of contact areas in the second connection area 4 . The second connecting line 11‴ is laid asymmetrically in the area of the second contact area 6 12 of a first pair 5 2 of contact areas in the first connection area 3 and in the area of the second contact area 9 22 of a second pair 10 2 of contact areas in the second connection area 4 .

Die erste Verbindungsleitung 7‴, die näher an der Umfangsfläche des Adapters 1‴ und damit näher an der Masseschirmung positioniert ist, weist einen geänderten Durchmesser, bevorzugt einen geringeren Durchmesser, als die dritte Verbindungsleitung 11‴ auf, die weiter entfernt von der Umfangsfläche des Adapters 1‴ und damit weiter entfernt von der Masseschirmung positioniert ist. Somit wird auch in diesem Fall die kapazitive Komponente der Impedanz zwischen ersten Anschlussbereich 3 und zweiten Anschlussbereich 4 des Adapters 1‴ auf den optimalen Wert reduziert.The first connection line 7‴, which is positioned closer to the peripheral surface of the adapter 1‴ and thus closer to the ground shield, has a changed diameter, preferably a smaller diameter, than the third connection line 11‴, which is further away from the peripheral surface of the adapter 1‴ and is therefore positioned further away from the ground shield. In this case, too, the capacitive component of the impedance between the first connection area 3 and the second connection area 4 of the adapter 1‴ is reduced to the optimum value.

Eine dritte Variante der Minimierung des kapazitiven Überkoppelns im Überkreuzungsbereich der ersten und dritten Verbindungsleitung, die jeweils zueinander überkreuzt angeordnet sind, ist in den Figuren 5A, 5B und 5C dargestellt:
Hierbei weisen die erste und dritte Verbindungsleitung 7‴ und 11‴′ der fünften Ausführungsform 1ʺ‴ des Adapters jeweils im Überkreuzungsbereich einen Materialabtrag 141 und 143 auf. Auf diese Weise ist der Abstand zwischen der ersten und der dritten Verbindungsleitung 7ʺʺ und 11ʺʺ vergrößert und das kapazitive Überkoppeln zwischen der ersten und der dritten Verbindungsleitung 7ʺʺ und 11ʺʺ reduziert.A third variant of minimizing the capacitive overcoupling in the crossover area of the first and third connecting lines, which are each arranged crossed over to one another, is described in Figures 5A, 5B and 5C shown:
The first and third connecting lines 7‴ and 11‴′ of the fifth embodiment 1″‴ of the adapter each have a material removal 14 1 and 14 3 in the crossing area. In this way, the distance between the first and the third connection line 7"" and 11"" is increased and the capacitive overcoupling between the first and the third connection line 7"" and 11"" is reduced.

Die näher an der Umfangfläche des Adapters 1ʺʺ und damit an der Masseschirmung geführte erste Verbindungsleitung 7ʺʺ weist einen geänderten Durchmesser, bevorzugt einen geringeren Durchmesser, als die weiter entfernt von der Umfangsfläche des Adapters 1ʺʺ geführte dritte Verbindungsleitung 11ʺʺ auf, um die kapazitive Komponente der Impedanz zwischen dem ersten Anschlussbereich 3 und dem zweiten Anschlussbereich 4 des Adapters 1ʺʺ auf den optimalen Wert zu reduzieren.The closer to the peripheral surface of the adapter 1" and thus to the ground shielding, the first connecting line 7" has a different diameter, preferably a smaller diameter, than the further away from the peripheral surface of the adapter 1" out third connecting line 11" to the capacitive component of the impedance between to reduce the first connection area 3 and the second connection area 4 of the adapter 1'' to the optimal value.

Da die erste und dritte Verbindungsleitung, die jeweils überkreuzt zueinander angeordnet sind, eine größere Länge als die zweite und vierte Verbindungsleitung aufweisen, die jeweils parallel zueinander angeordnet sind, kommt es zwischen den Signalanteilen des differenziellen Signals in der ersten und zweiten Verbindungsleitung wie auch zwischen den Signalanteilen des differenziellen Signals in der dritten und vierten Verbindungsleitung zu einem Laufzeitunterschied und damit zu einer Phasenverschiebung. Diese Phasenverschiebung zwischen den Signalanteilen der einzelnen differenziellen Signale bewirkt, dass die Signalanteile der einzelnen differenziellen Signale nach Durchlaufen der Verbindungsleitungen nicht mehr die für ein differenzielles Signal erforderliche Phasendifferenz von 180° aufweisen.Since the first and third connecting lines, which are each arranged crossed over one another, have a greater length than the second and fourth connecting lines, which are each arranged parallel to one another, there is a difference between the signal components of the differential signal in the first and second connecting lines as well as between the Signal components of the differential signal in the third and fourth connecting line to a transit time difference and thus to a phase shift. This phase shift between the signal components of the individual differential signals has the effect that the signal components of the individual differential signals no longer have the phase difference of 180° required for a differential signal after passing through the connecting lines.

Zur Kompensation dieser Phasenverschiebung wird die Ausbreitungsgeschwindigkeit der Signalanteile des differenziellen HF-Signals in den jeweils sich überkreuzenden Verbindungsleitungen relativ zur Ausbreitungsgeschwindigkeit der Signalanteile der differenziellen HF-Signale in den jeweils parallel verlaufenden Verbindungsleitungen erhöht.To compensate for this phase shift, the propagation speed of the signal components of the differential HF signal in the respectively crossing connecting lines is increased relative to the propagation speed of the signal components of the differential HF signals in the respectively parallel connecting lines.

Hierzu sind die Verbindungsleitungen, die sich jeweils überkreuzen, von einem Material mit einer niedrigeren Permittivität umgeben als die Verbindungsleitungen, die jeweils parallel verlaufen. Hierbei kann einerseits bereits die Ummantelung des elektrischen Leiters der Verbindungsleitung oder ein die Ummantelung des elektrischen Leiters der Verbindungsleitung zusätzlich umgebendes Material hinsichtlich einer geeigneten Permittivität ausgewählt werden.For this purpose, the connecting lines, which cross each other, are surrounded by a material with a lower permittivity than the connecting lines, which each run parallel. Here, on the one hand, the sheathing of the electrical conductor of the connecting line or a material additionally surrounding the sheathing of the electrical conductor of the connecting line can be selected with regard to a suitable permittivity.

In Fig. 6 ist ein erfindungsgemäßes Kabel 13 dargestellt, an dessen Ende ein Adapter 1 befestigt ist. Das Kabel 13 beinhaltet zwei parallele, geschirmte Paare von Innenleitern. Diese beiden Paare von Innenleitern werden an die beiden ersten Paare 51 und 52 von Kontaktbereichen im ersten Anschlussbereich 3 des Adapters herangeführt, die jeweils als Bohrungen oder Ausnehmungen realisiert sind, und durch diese Bohrungen bzw. Ausnehmungen hindurchgeführt.In 6 a cable 13 according to the invention is shown, at the end of which an adapter 1 is attached. The cable 13 includes two parallel, shielded pairs of inner conductors. These two pairs of inner conductors are brought up to the two first pairs 5 1 and 5 2 of contact areas in the first connection area 3 of the adapter, which are each implemented as bores or recesses, and passed through these bores or recesses.

Äquivalent wie die erste, zweite, dritte und vierte Verbindungsleitung 7, 8, 11 und 12 bei der ersten Ausführungsform des Adapters 1 gemäß der Figuren 1A, 1B und 1C werden die Innenleiter 8v und 12v der beiden Paare von Innenleitern von den einzelnen zweiten Kontaktbereichen des ersten Anschlussbereiches 3 zum direkt gegenüberliegenden zweiten Kontaktbereich des zweiten Anschlussbereich 4 geführt, während die Innenleiter 7v und 11v der beiden Paare von Innenleitern von den einzelnen ersten Kontaktbereichen des ersten Anschlussbereiches 3 zu den an der Längsachse 2 gespiegelten ersten Kontaktbereichen des zweiten Anschlussbereiches 4 geführt werden.Equivalent to the first, second, third and fourth connection lines 7, 8, 11 and 12 in the first embodiment of the adapter 1 according to FIG Figures 1A, 1B and 1C the inner conductors 8 v and 12 v of the two pairs of inner conductors are routed from the individual second contact areas of the first connection area 3 to the directly opposite second contact area of the second connection area 4, while the inner conductors 7 v and 11 v of the two pairs of inner conductors are routed from the individual first Contact areas of the first connection area 3 to those on the longitudinal axis 2 mirrored first contact areas of the second connection area 4 are performed.

Die in den Figuren 2, 3A, 4A und 5A jeweils dargestellte zweite, dritte, vierte und fünfte Ausführungsform des Adapters kann äquivalent in dem am Ende des erfindungsgemäßen Kabels 13 befestigten Adapter realisiert sein.The in the figures 2 , 3A , 4A and 5A The illustrated second, third, fourth and fifth embodiment of the adapter can be equivalently implemented in the adapter attached to the end of the cable 13 according to the invention.
