Description

Die Erfindung betrifft einen elektrischen Steckverbinder nach dem Oberbegriff des Anspruchs 1.The invention relates to an electrical connector according to the preamble of claim 1.

Aus der EP 0 558 225 B2 ist ein elektrischer Steckverbinder mit einem Gehäuse und einer im Gehäuse positionierten Verbindungseinrichtung bekannt, wobei die Verbindungseinrichtung mehrere im Wesentlichen parallel zueinander verlaufende, elektrische Leiter umfasst, die einen elektrischen Leitungsweg zwischen Eingangsanschlüssen und Ausgangsanschlüssen der Verbindungseinrichtung bilden.From the EP 0 558 225 B2 is an electrical connector with a housing and a housing positioned in the connector means known, wherein the connecting means comprises a plurality of substantially parallel electrical conductors forming an electrical conduction path between the input terminals and output terminals of the connecting means.

Zur Minimierung von Nahnebensprechen zwischen den elektrischen Leitern ist es aus der EP 0 558 225 B2 bereits bekannt, zumindest einige benachbarte elektrische Leiter ohne elektrischen Kontakt zwischen denselben zu überkreuzen. Hiermit kann in gewissem Umfang bereits Nahnebensprechen minimiert werden. Jedoch insbesondere dann, wenn der von den elektrischen Leitern bereitgestellte elektrische Leitungsweg zwischen den Eingangsanschlüssen und den Ausgangsanschlüssen der Verbindungseinrichtung kurz ist und/oder wenn Datensignale mit hohen Übertragungsfrequenzen von mehr als 500 MHz übertragen werden sollen, ist die hierdurch erzielbare Minimierung des Nahnebensprechens nicht ausreichend.To minimize near-end crosstalk between the electrical conductors, it is out of the EP 0 558 225 B2 already known, at least to cross some adjacent electrical conductors without electrical contact between them. This can to a certain extent already minimize near-end crosstalk. However, especially when the electrical path provided by the electrical conductors between the input terminals and the output terminals of the connection means is short and / or when data signals having high transmission frequencies of more than 500 MHz are to be transmitted, the minimization of the near-end crosstalk achievable thereby is not sufficient.

EP 1596478 offenbart einen elektrischen Steckverbinder mit den Merkmalen des Oberbegriffs des Anspruchs 1. EP 1596478 discloses an electrical connector having the features of the preamble of claim 1.

Der hier vorliegenden Erfindung liegt das Problem zu Grunde, einen hinsichtlich der erzielbaren Minimierung von Nahnebensprechen verbesserten elektrischen Steckverbinder zu schaffen.The present invention is based on the problem of providing an improved with regard to the achievable minimization of near-end crosstalk electrical connector.

Dieses Problem wird durch einen elektrischen Steckverbinder gemäß Anspruch 1 gelöst. Erfindungsgemäß ist der elektrischen Steckverbinder dadurch gekennzeichnet, dass a) zwischen dem ersten Leitungspaar und dem zweiten Leitungspaar eine Nahnebensprechkompensation derart aufgebaut ist, dass zumindest vor der Überkreuzung der Leiter des zweiten Leitungspaars im Bereich von freien Enden derselben einerseits zwischen den hinlaufenden Leiter des ersten Leitungspaars und den rücklaufenden Leiter des zweiten Leitungspaars eine Kapazität und andererseits zwischen den rücklaufenden Leiter des ersten Leitungspaars und den hinlaufenden Leiter des zweiten Leitungspaars eine Kapazität geschaltet ist; b) zwischen dem ersten Leitungspaar und dem dritten Leitungspaar eine Nahnebensprechkompensation derart aufgebaut ist, dass zumindest vor der Überkreuzung der Leiter des dritten Leitungspaars zwischen den hinlaufenden Leiter des ersten Leitungspaars und den hinlaufenden Leiter des dritten Leitungspaars im Bereich von freien Enden derselben eine Kapazität und nach der Überkreuzung der Leiter des dritten Leitungspaars zwischen den hinlaufenden Leiter des ersten Leitungspaars und den rücklaufenden Leiter des dritten Leitungspaars eine Kapazität geschaltet ist; c) zwischen dem ersten Leitungspaar und dem vierten Leitungspaar eine Nahnebensprechkompensation derart aufgebaut ist, dass zumindest vor der Überkreuzung der Leiter des vierten Leitungspaars zwischen den hinlaufenden Leiter des ersten Leitungspaars und den rücklaufenden Leiter des vierten Leitungspaars im Bereich von freien Enden derselben eine Kapazität und nach der Überkreuzung der Leiter des vierten Leitungspaars zwischen den rücklaufenden Leiter des ersten Leitungspaars und den rücklaufenden Leiter des vierten Leitungspaars eine Kapazität geschaltet ist.This problem is solved by an electrical connector according to claim 1. According to the electrical connector is characterized in that a) between the first pair of wires and the second pair of lines Nahnebensprechkompensation is constructed such that at least before the crossing of the conductor of the second pair of lines in the region of free ends thereof on the one hand between the leading conductor of the first pair of lines and a capacitance is connected to the return conductor of the second pair of wires and, on the other hand, a capacitance is connected between the return conductor of the first pair of wires and the outgoing conductor of the second pair of wires; b) between the first pair of wires and the third pair of wires a Nahnebensprechkompensation is constructed such that at least before the crossing of the conductor of the third pair of wires between the leading conductor of the first pair of lines and the leading conductor of the third pair of lines in the region of free ends thereof, a capacity and after the crossover of the conductors of the third pair of wires between the leading conductors of the first pair of wires and the return conductors of the third pair of wires is connected to a capacitance; c) between the first line pair and the fourth line pair, a Nahnebensprechkompensation is constructed such that at least before the crossing of the conductor of the fourth pair of lines between the leading conductor of the first pair of lines and the returning conductor of the fourth pair of lines in the region of free ends thereof, a capacity and after the crossover of the conductor of the fourth pair of lines between the returning conductor of the first pair of lines and the returning conductor of the fourth pair of lines, a capacitance is connected.

Mit einem solchen elektrischen Steckverbinder kann insbesondere dann, wenn der elektrische Leitungsweg zwischen den Eingangsanschlüssen und den Ausgangsanschlüssen kurz ist und/oder wenn Datensignale mit hohen Übertragungsfrequenzen übertragen werden sollen, eine gute Minimierung des Nahnebensprechens erzielt werden.With such an electrical connector, in particular, when the electrical conduction path between the input terminals and the output terminals is short and / or when data signals having high transmission frequencies are to be transmitted, a good minimization of the near-end crosstalk can be achieved.

Die elektrischen Leiter 1 bis 8 bilden einen elektrischen Leitungsweg zwischen Eingangsanschlüssen 9 und Ausgangsanschlüssen 10 der Verbindungseinrichtung. Fig. 1 schematically shows an equivalent circuit diagram of an electrical connector according to the invention according to a first embodiment of the invention in the region of substantially parallel to each other extending electrical conductors of the housing positioned in the connecting device, wherein according to FIG Fig. 1 the connecting device comprises a total of eight electrical conductors 1, 2, 3, 4, 5, 6, 7 and 8. The electrical conductors 1 to 8 form an electrical conduction path between input terminals 9 and output terminals 10 of the connection device.

Die Leiter 1 bis 8 des Steckverbinders der Fig. 1 bilden insgesamt vier Leitungspaare, nämlich ein erstes Leitungspaar 11, ein zweites Leitungspaar 12, ein drittes Leitungspaar 13 und eine viertes Leitungspaar 14. Das erste Leitungspaar 11 wird von den Leitern 3 und 6 gebildet, wobei es sich beim Leiter 3 um den hinlaufenden Leiter und beim Leiter 6 um den rücklaufenden Leiter handelt. Das zweite Leitungspaar umfasst die Leiter 4 und 5, wobei es sich beim Leiter 4 um den hinlaufenden Leiter und beim Leiter 5 um den rücklaufenden Leiter des zweiten Leitungspaars handelt. Das dritte Leitungspaar 13 umfasst die Leiter 1 und 2 und das vierte Leitungspaar 14 die Leiter 7 und 8, wobei es sich bei den Leitern 2 und 8 jeweils um die hinlaufenden Leiter und bei den Leitern 1 und 7 jeweils um die rücklaufenden Leiter der entsprechenden Leitungspaare 13, 14 handelt.The conductors 1 to 8 of the connector of Fig. 1 form a total of four pairs of lines, namely a first line pair 11, a second line pair 12, a third line pair 13 and a fourth line pair 14. The first line pair 11 is formed by the conductors 3 and 6, wherein it is the conductor 3 to the leading conductor and at the conductor 6 is about the returning conductor.

Die hinlaufenden Leiter 2, 3, 4, 8 sind jeweils mit (+) und die rücklaufenden Leiter 1, 5, 6, 7 jeweils mit (-) gekennzeichnet.The leading conductors 2, 3, 4, 8 are each marked with (+) and the returning conductors 1, 5, 6, 7 each with (-).

Gemäß Fig. 1 sind einige benachbarte Leiter 1 und 2, 4 und 5 sowie 7 und 8, also die Leiter des zweiten Leitungspaars 12, des dritten Leitungspaars 13 und des vierten Leitungspaars 14, zur Minimierung von Nahnebensprechen zwischen den elektrischen Leitern ohne elektrischen Kontakt zwischen denselben überkreuzt, wobei die Überkreuzung der Leiter 4, 5 des zweiten Leitungspaars 12 durch die Bezugsziffer 15, die Überkreuzung der elektrischen Leiter 1, 2 des dritten Leitungspaars 13 durch die Bezugsziffer 16 und die Überkreuzung der Leiter 7, 8 des vierten Leitungspaars 14 durch die Bezugsziffer 17 gekennzeichnet sind. Durch diese Überkreuzung der benachbarten elektrischen Leiter 1 und 2, 4 und 5 sowie 7 und 8 kann bereits in gewissem Umfang eine Nahnebensprechkompensation realisiert werden.According to Fig. 1 For example, some adjacent conductors 1 and 2, 4 and 5, and 7 and 8, the conductors of the second pair of leads 12, the third pair of leads 13 and the fourth pair 14, are crossed to minimize near-end crosstalk between the conductors without electrical contact therebetween the crossing of the conductors 4, 5 of the second line pair 12 by the reference numeral 15, the crossing of the electrical conductors 1, 2 of the third line pair 13 by the reference numeral 16 and the crossing of the conductors 7, 8 of the fourth line pair 14 by the reference numeral 17 are , By this crossover of the adjacent electrical conductors 1 and 2, 4 and 5 and 7 and 8, a Nahnebensprechkompensation can already be realized to some extent.

Beim erfindungsgemäßen elektrischen Steckverbinder ist gemäß Fig. 1 zwischen dem ersten Leitungspaar 11 und dem zweiten Leitungspaar 12 eine Nahnebensprechkompensation derart aufgebaut, dass vor der Überkreuzung 15 der Leiter 4 und 5 des zweiten Leitungspaars 12 im Bereich von freien Enden der Leiter 3, 4, 5 und 6 einerseits zwischen den hinlaufenden Leiter 3 des ersten Leitungspaars 11 und des rücklaufenden Leiter 5 des zweiten Leitungspaars 12 eine Kapazität C35 und andererseits zwischen den rücklaufenden Leiter 6 des ersten Leitungspaars und den hinlaufenden Leiter 4 des zweiten Leitungspaars 12 eine Kapazität C46 geschaltet ist.In the electrical connector according to the invention is according to Fig. 1 between the first line pair 11 and the second line pair 12, a Nahnebensprechkompensation constructed such that before the crossover 15 of the conductors 4 and 5 of the second line pair 12 in the region of free ends of the conductors 3, 4, 5 and 6, on the one hand between the running conductor 3 of First line pair 11 and the returning conductor 5 of the second line pair 12, a capacitor C35 and on the other hand between the returning conductor 6 of the first line pair and the leading conductor 4 of the second line pair 12, a capacitor C46 is connected.

Fig. 2 zeigt eine vorteilhafte Weiterbildung des elektrischen Steckverbinders der Fig. 1, weshalb nachfolgend zur Vermeidung unnötiger Wiederholungen für gleiche Baugruppen gleiche Bezugsziffern verwendet werden und im Zusammenhang mit Fig. 2 nur die Details beschrieben werden, durch die sich das Ausführungsbeispiel der Fig. 2 vom Ausführungsbeispiel der Fig. 1 unterscheidet. Fig. 2 shows an advantageous development of the electrical connector of Fig. 1 Therefore, the same reference numerals are used to avoid unnecessary repetition for the same components below and in connection with Fig. 2 only the details will be described by which the embodiment of the Fig. 2 from the embodiment of Fig. 1 different.

Ebenso ist zwischen den rücklaufenden Leiter 6 des ersten Leitungspaars 11 und den rücklaufenden Leiter 5 des zweiten Leitungspaars 12 nach der Überkreuzung 15 der Leiter 4 und 5 des zweiten Leitungspaars 12 und damit im Bereich der Ausgangsanschlüsse 10 zwischen dieselben eine weitere Kapazität, nämlich die Kapazität CF56, geschaltet. Bei den beiden Kapazitäten CF34 und CF56 handelt es sich jeweils um koppelnde Interdigitalkapazitäten bzw. sogenannte Fingerkapazitäten. Auch diese Kapazitäten CF34 und CF56 sind jeweils über eine Stichleitung 18 an die entsprechenden elektrischen Leiter 3 und 5 sowie 4 und 6 von erstem Leitungspaar 11 und zweitem Leitungspaar 12 angeschlossen.Likewise, between the returning conductors 6 of the first pair of wires 11 and the return wires 5 of the second pair of wires 12 after crossing 15, the conductors 4 and 5 of the second pair of wires 12 and thus in the region of the output terminals 10 therebetween another capacitance, namely the capacitance CF56 , switched.

Eine weitere vorteilhafte Weiterbildung des Ausführungsbeispiels der Fig. 1 zeigt Fig. 3, wobei auch für das Ausführungsbeispiel der Fig. 3 für gleiche Baugruppen gleiche Bezugsziffern verwendet werden und nur solche Details beschrieben werden, durch die sich das Ausführungsbeispiel der Fig. 3 vom Ausführungsbeispiel der Fig. 1 unterscheidet.A further advantageous embodiment of the embodiment of Fig. 1 shows Fig. 3 , wherein also for the embodiment of Fig. 3 for identical components same reference numerals are used and only those details are described by which the embodiment of the Fig. 3 from the embodiment of Fig. 1 different.

Weiterhin ist im Ausführungsbeispiel der Fig. 3 zur Nahnebensprechkompensation zwischen dem zweiten Leitungspaar 12 und dem dritten Leitungspaar 13 nach den Überkreuzungspunkten 15 und 16 der Leiter 3, 4 des zweiten Leitungspaars 12 und der Leiter 1, 2 des dritten Leitungspaars 13 zwischen den hinlaufenden Leiter 2 des dritten Leitungspaars 13 und den rücklaufenden Leiter 5 des zweiten Leitungspaars 12 eine Kapazität C25 geschaltet, der wiederum als Plattenkondensator ausgebildet ist und über eine Stichleitung 18 an die Leiter 2, 5 angeschlossen ist.So is the embodiment of the Fig. 3 the near-end crosstalk compensation between the first pair of lines 11 and the fourth pair of lines 14 so further developed that after the crossover 17 of the conductors 7, 8 of the fourth pair 14 and thus in the region of the output terminals 10 between the leading conductor 8 of the fourth pair of wires 14 and the returning conductor. 6 of the first pair of lines 11, a capacitor C68 is connected, which is designed as a plate capacitor and is connected via a branch line 18 to the conductors 6, 8. Furthermore, in the embodiment of Fig. 3 for near-end crosstalk compensation between the second line pair 12 and the third line pair 13 after the crossover points 15 and 16 of the conductors 3, 4 of the second line pair 12 and the conductors 1, 2 of the third line pair 13 between the outgoing conductors 2 of the third line pair 13 and the returning conductor 5 of the second line pair 12, a capacitor C25 connected, which in turn is designed as a plate capacitor and is connected via a branch line 18 to the conductors 2, 5.

Das weitere Ausführungsbeispiel der Fig. 4 ist eine Kombination der Ausführungsbeispiele Fig. 2 und 3, dasselbe umfasst demnach sowohl die Kapazitäten CF34 und CF56 als auch die Kapazitäten C25 und C68, jeweils im Bereich der Ausgangsanschlüsse 10.The further embodiment of the Fig. 4 is a combination of the embodiments Fig. 2 and 3 , the same therefore comprises both the capacitances CF34 and CF56 and the capacitances C25 and C68, in each case in the region of the output terminals 10.

Durch die geringe Anzahl der benötigten Kapazitäten kann ein zuverlässiger und reproduzierbarer elektrischer Steckverbinder mit stabiler elektrischer Performance bereitgestellt werden. Durch die einfache Nahnebensprechkompensation kann ein kostengünstiger elektrischer Steckverbinder bereitgestellt werden.Due to the small number of required capacities, a reliable and reproducible electrical connector with stable electrical performance can be provided. Simple low level crosstalk compensation can provide a low cost electrical connector.

Das erfindungsgemäße Prinzip eines elektrischen Steckverbinders kann für beliebige Geometrien von Kontaktfedern, die Bestandteil des elektrischen Leitungswegs der elektrischen Leiter sind, eingesetzt werden.The inventive principle of an electrical connector can be used for any geometry of contact springs, which are part of the electrical conduction path of the electrical conductors.
