Description

Die Erfindung betrifft ein Steckverbindungsteil, insbesondere für RJ-45-Steckverbinder, gemäss dem Oberbegriff von Anspruch 1.The invention relates to a connector part, especially for RJ-45 connectors, according to the Preamble of claim 1.

Ein RJ-45-Steckverbinder ist ein nach DIN EN 60 603 Teil 7/IEC 60 603-7 genormter und weltweit angewandter Standard für Steckverbinder in Kommunikations- und Datennetzen. Herkömmliche Buchsen für derartige RJ-45-Steckverbinder haben eine genormte Anordnung der Kontakte und der Geometrie der Öffnung, was auch als Steckgesicht bezeichnet wird, und besitzen Schneidklemmen beziehungsweise Lötpins zum Anschluss eines Datenkabels oder zum Anschluss an eine Printplatte.An RJ-45 connector is a part according to DIN EN 60 603 7 / IEC 60 603-7 standardized and applied worldwide for connectors in communication and data networks. Conventional sockets for such RJ-45 connectors have a standardized arrangement of the contacts and the Geometry of the opening, also known as the mating face is, and have insulation piercing or Solder pins for connecting a data cable or for connecting on a printed circuit board.

Aus der Druckschrift EP 0 955 703 A2 ist eine derartige Buchse bekannt, deren acht Leiterbahnen im wesentlichen gegenseitig parallel verlaufend angeordnet sind. Diese Buchse ist für eine Bandbreite der Kategorie 5 (100 MHz Bandbreite) ausgelegt.One such is known from EP 0 955 703 A2 Jack known, the eight conductor tracks essentially are arranged mutually parallel. This Socket is for a bandwidth of category 5 (100 MHz Bandwidth).

Nachteilig an dieser bekannten Buchse ist die Tatsache, dass sie für elektrische Signale mit einer Bandbreite von über 100 MHz ungenügend ist, weil zwischen den Leiterbahnen ein derart hohes Übersprechen auftritt, dass die übertragenen Signale unzulässig verzerrt werden. Auf Grund des zunehmenden Bandbreitenbedarfs in Kommunikations- und Datennetzen besteht ein Bedarf nach Steckverbindern höherer Bandbreite. Deshalb wurde in der Normierungsgruppe der RJ45-Norm eine neue Kategorie 6 definiert, welche Steckverbinder mit 200 MHz Bandbreite definiert. The disadvantage of this known socket is the fact that they're for electrical signals with a bandwidth of above 100 MHz is insufficient because between the conductor tracks such high crosstalk occurs that the transmitted signals are distorted. Because of the increasing bandwidth requirements in communication and Data networks have a need for connectors higher bandwidth. That is why in the standardization group the RJ45 standard defines a new category 6, which Connector defined with 200 MHz bandwidth.

Es ist Aufgabe der vorliegenden Erfindung, ein Steckverbindungsteil, insbesondere für RJ45-Steckverbinder, anzugeben, welches auch für elektrische Signale mit einer Bandbreite von zumindest 200 MHz ein geringes Übersprechen aufweist.It is an object of the present invention to provide a connector part, especially for RJ45 connectors, which also for electrical signals with a Bandwidth of at least 200 MHz a low crosstalk having.

Diese Aufgabe wird gelöst mit einem Steckverbindungsteil aufweisend die Merkmale von Anspruch 1. Die Unteransprüche 2 bis 10 betreffen vorteilhafte Weiterbildungen des erfindungsgemässen Steckverbindungsteils.This problem is solved with a connector part having the features of claim 1. The subclaims 2 to 10 relate to advantageous developments of the connector part according to the invention.

Die Aufgabe wird insbesondere gelöst mit einem Steckverbindungsteil umfassend eine Mehrzahl von Leiterbahnen, welche am einen Ende eine Kontaktfeder und am anderen Ende einen Ausgangskontakt aufweisen, wobei die Kontaktfedern ausgehend von einem dem Ausgangskontakt abgewandten Ende zu dem Ausgangskontakt hin verlaufen, und wobei die Leiterbahnen in einem den Kontaktfedern nachfolgenden Kompensationsabschnitt zumindest teilweise gegenseitig überkreuzt verlaufen, und die Leiterbahnen entlang einer Teillänge des Kompensationsabschnittes zumindest teilweise gegenseitig übereinanderliegend und mittels eines dazwischen angeordneten Isolators elektrisch getrennt verlaufen.The object is achieved in particular with a plug connection part comprising a plurality of conductor tracks, which has a contact spring on one end and the other end have an output contact, the contact springs starting from an end facing away from the output contact to the output contact, and the Conductor tracks in one following the contact springs Compensation section at least partially mutually crossed, and the traces along one Part length of the compensation section at least partially mutually superimposed and by means of a isolator arranged between them electrically isolated run.

Die genannten Normen für RJ45-Steckverbindungen enthalten eine Festlegung für die Ausgestaltung des Steckgesichts, wogegen für den Verlauf der Kontakte aus dem Steckbereich hinaus keine Vorschriften bestehen. Daher sind RJ45-Steckverbindungen mit einer Vielzahl unterschiedlich angeordneter Leiterbahnen bekannt. Insbesondere bei RJ-45-Steckverbindungen der Kategorie 5 ist es bekannt, beispielsweise aus der genannten Druckschrift, den Verlauf der Leiterbahnen derart anzuordnen, dass eine gezielte Übersprechkompensation auftritt. All diesen für eine Signalbandbreite von 100 MHz ausgelegten Steckverbindungen ist gemeinsam, dass sie aus folgenden, physikalischen Gründen für höhere Bandbreiten kaum oder gar nicht geeignet sind. Die mechanischen Dimensionen dieser Systeme, insbesondere der Abstand zwischen Stecker und Kompensation, wie auch die Ausdehnung der Kompensationen, sind so gross, dass bei den hohen Frequenzen eine zusätzliche Phasenverschiebung zwischen dem Störsignal und dem Kompensationssignal auftritt, welche die Effektivität der vorhandenen Kompensation für diese Frequenzen einschränkt.The mentioned standards for RJ45 plug connections are included a definition for the design of the mating face, whereas for the course of the contacts from the mating area there are no regulations. Therefore, RJ45 plug connections are with a variety of different arranged conductor tracks known. Especially with RJ-45 connectors Category 5 is known for example from the publication mentioned, the course Arrange the conductor tracks so that a targeted Crosstalk compensation occurs. All of these for one Signal bandwidth of 100 MHz plug connections has in common that it consists of the following, physical Reasons for higher bandwidths hardly or not at all are suitable. The mechanical dimensions of this Systems, especially the distance between the connector and Compensation, as well as the expansion of the compensations, are so big that at high frequencies one additional phase shift between the interference signal and the compensation signal that affects the effectiveness the existing compensation for these frequencies restricted.

Steckverbindungssysteme für eine Signalbandbreite von über 100 MHz müssen daher aus physikalischen Gründen sehr durchdacht konzipiert werden. Dabei ist insbesondere zu berücksichtigen, dass die RJ45-Norm einen Stecker mit parallel verlaufenden Leitern und einem aufgespreizten Paar 3/6 vorschreibt, was unweigerlich zu einem erhöhten Übersprechen führt. Ein RJ45-Steckverbinder für hohe Signalbandbreiten ist daher nur dann realisierbar, wenn es mit geeigneten technischen Massnahmen gelingt eine Übersprechkompensation zu erwirken.Connector systems for a signal bandwidth of over 100 MHz is therefore very important for physical reasons thoughtfully designed. In particular, it is too take into account that the RJ45 standard has a connector parallel conductors and a spread Pair 3/6 prescribes, which inevitably leads to an increased Crosstalk leads. An RJ45 connector for high Signal bandwidths can therefore only be realized if it is with suitable technical measures To achieve crosstalk compensation.

Das erfindungsgemässe Steckverbindungsteil weist eine Kompensation des Übersprechens auf, wobei die Kompensation extrem kompakt ausgestaltet ist und sowohl kapazitive wie auch induktive Kopplungspfade enthält. Die Leiterbahnen des Steckverbindungsteils weisen eine minimale räumliche Ausdehnung auf. Zudem sind gewisse Leiterbahnen überkreuzt und zur gegenseitigen Kompensation zudem in zwei parallelen Ebenen verlaufend geführt, wobei zwischen diesen beiden parallelen Ebenen ein elektrischer Isolator beziehungsweise ein Dielektrikum angeordnet ist, um einen kapazitiven Kopplungspfad zu erlangen.The connector part according to the invention has a Compensation of crosstalk, the compensation is extremely compact and both capacitive and also contains inductive coupling paths. The conductor tracks of the connector part have a minimal spatial Extension to. In addition, certain conductor tracks are crossed and for mutual compensation in two parallel planes running between an electrical insulator to these two parallel planes or a dielectric is arranged around a to achieve capacitive coupling path.

Ein Vorteil des Steckverbinders umfassend das erfindungsgemässe Steckverbindungsteil ist die Tatsache, dass dieser selbst bei Signalen mit 200 MHz Bandbreite nur ein Übersprechen von höchstens -48 dB aufweist.An advantage of the connector comprising the inventive Connector part is the fact that this even with signals with a bandwidth of 200 MHz only one Crosstalk of at most -48 dB.

Ein weiterer Vorteil ist die Tatsache, dass das Steckverbindungsteil sehr kompakt und klein ausgestaltet ist. Dies ermöglicht bestehende Buchsen durch eine Buchse enthaltend das erfindungsgemässe, breitbandige Steckverbindungsteil auszutauschen, um dadurch die Bandbreite bestehender Neztwerke zu erhöhen. Die in einem Gebäude fest verlegten, gegenseitig verdrillten, elektrischen Leiter müssen dabei nicht ausgewechselt werden, was eine kostengünstige Erweiterung der Bandbreite erlaubt.Another advantage is the fact that the connector part is very compact and small. This enables existing sockets by containing a socket the broadband connector part according to the invention exchange, thereby the bandwidth of existing Increase network. Those permanently installed in a building mutually twisted electrical conductors must be used not be replaced, which is an inexpensive Bandwidth expansion allowed.

Das erfindungsgemässe Steckverbindungsteil kann nebst der nachfolgend offenbarten, 8-poligen Ausführungsform auch mit anderer Polzahl ausgebildet sein, beispielsweise in 6-poliger Ausführung gemäss der RJ11-Norm.The connector part according to the invention can in addition to 8-pin embodiment also disclosed below be designed with a different number of poles, for example in 6-pole Version according to the RJ11 standard.

At the end of cable 82 is an RJ45 Plug 83 or an 8-pin module plug 83 arranged. The cable 82 comprises 4 pairs of each other twisted electrical conductor, also in English as "unshielded twisted pair (UTP)", and is for example for high bandwidth computer networks or suitable for high speeds.

Fig. 2 zeigt ein Steckverbindungsteil 80 aus Blickrichtung B. Acht Leiterbahnen 1-8 weisen am einen Ende je eine Kontaktfeder 11-18 auf und am anderen Ende je einen Ausgangskontakt 71-78, der als Schneidklemme ausgestaltet ist. Die Kontaktfedern 11-18 verlaufen entlang eines Kontaktfedernabschnittes 19 in einer gemeinsamen Fläche und gegenseitig parallel. Die Kontaktfedern 11-18 sind in ihrer Längsrichtung v-förmig verlaufend ausgestaltet und weisen je eine Kontaktstelle lla-18a auf, welche bei eingefügtem Stecker 83 auf den jeweiligen Kontaktstellen des Steckers 83 aufliegen. Die Kontaktfedern 11-18 beginnen am einen, den Ausgangskontakten 71-78 abgewandten Ende, und verlaufen zu den Ausgangskontakten 71-78 hin. Die Kontaktfedern 11-18 münden in einen Umlenkungsabschnitt 29, innerhalb welchem die Leiterbahnen 1-8 um etwa 90 Grad umgelenkt sind. Danach folgt ein Überkreuzungsabschnitt 39, innerhalb welchem die Leiterpaare 1,2; 4,5 und 7,8 sich gegenseitig überkreuzen. Nachfolgend verlaufen die Leiterpaare 1-8 in zwei parallelen, im wesentlichen in Verlaufsrichtung der Kontaktfedern 11-18 beabstandeten Ebenen, sodass sich ein Abschnitt 49 von parallel und versetzt verlaufenden Leiterbahnen 1-8 ausbildet. Zwischen den beiden beabstandeten Ebenen ist ein elektrischer Isolator 40 angeordnet, welcher ein Dielektrikum ausbildet. Die im Abschnitt 49 angeordneten Teillängen 41-48 der Leiterbahnen 1-8 sind teilweise in Längsrichtung des Isolators 40 verbreitet ausgestaltet, um eine entsprechend grössere Kapazität zu bewirken. Zudem sind einzelne Teillängen 41-48 bezüglich dem Isolator 40 gegenüberliegend angeordnet, um dadurch ebenfalls eine erhöhte Kapazität zwischen den jeweiligen Leiterbahnen 1-8 zu bewirken. Die Leiterbahnen 1-8 münden nach dem Abschnitt 49 in einen Umlenkabschnitt 59, innerhalb welchem die Leiterbahnen 1-8 um etwa 90 Grad umgelenkt sind. Nachfolgend oder zusammenfallend mit dem Umlenkabschnitt 59 ist ein Überkreuzungsabschnitt 69 angeordnet, innerhalb welchem sich die Leiter 1-8, wie in Fig. 4b in einer abgewickelten Aufsicht dargestellt, überkreuzen. Dem Überkreuzungsabschnitt 69 nachfolgend ist ein Schneidklemmbereich 79 mit Schneid-Klemm-Kontakten 71-78 angeordnet. Fig. 2 shows a connector part 80 from the viewing direction B. Eight tracks 1-8 have one at one end Contact spring 11-18 on and at the other end one each Output contact 71-78, which is designed as an insulation displacement terminal is. The contact springs 11-18 run along one Contact spring section 19 in a common area and mutually parallel. The contact springs 11-18 are in designed in their longitudinal direction V-shaped and each have a contact point lla-18a, which at inserted plug 83 on the respective contact points of the plug 83 rest. The contact springs 11-18 start at one, facing away from the output contacts 71-78 End, and run to the output contacts 71-78. The contact springs 11-18 open into a deflection section 29, within which the conductor tracks 1-8 by about Are deflected 90 degrees. This is followed by a crossover section 39, within which the conductor pairs 1,2; 4.5 and 7,8 cross each other. Run below the conductor pairs 1-8 in two parallel, essentially in Direction of travel of the contact springs 11-18 spaced Levels so that a section 49 of parallel and forms offset traces 1-8. Between the two spaced apart levels is electrical Insulator 40 arranged, which is a dielectric trains. The partial lengths 41-48 arranged in section 49 of the conductor tracks 1-8 are partially in the longitudinal direction of the insulator 40 widely configured to be a to effect correspondingly greater capacity. Also are individual partial lengths 41-48 with respect to the insulator 40 arranged opposite, thereby also a increased capacity between the respective conductor tracks 1-8 to effect. The conductor tracks 1-8 open after the Section 49 into a deflecting section 59, inside which deflects the conductor tracks 1-8 by about 90 degrees are. Subsequent or coincident with the Deflection section 59 is a crossover section 69 arranged, within which the conductors 1-8, as in 4b shown in a developed top view, cross over. The crossover section 69 is subsequent an insulation displacement region 79 with insulation displacement contacts 71-78 arranged.

Der Verlauf der Leiterbahnen 1-8 kann auch derart ausgestaltet sein, dass sich zumindest einige der Leiterbahnen 1-8 im Umlenkabschnitt 29, 59 zudem gegenseitig überkreuzen, sodass der Umlenkabschnitt 29, 59 zudem dem Überkreuzungsabschnitt 39, 69 entspricht.The course of the conductor tracks 1-8 can also be configured in this way be at least some of the traces 1-8 also cross each other in the deflection section 29, 59, so that the deflecting section 29, 59 also the Crossover section 39, 69 corresponds.

Fig. 3 zeigt das in Fig. 2 dargestellte Steckverbindungsteil 80 aus Blickrichtung A. Gut sichtbar sind die Teillängen beziehungsweise Ausformungen 43,46 der Leiterbahnen 3 und 6 im Bereich des Abschnittes 49. Die Ausformungen 43, 46 sind, einzig durch den Isolator 40 getrennt, den Ausformungen 42, 45, 44, 48 gegenüberliegend und gegenseitig parallel verlaufend angeordnet.Fig. 3 shows the connector part shown in Fig. 2 80 from viewing direction A. They are clearly visible Part lengths or formations 43.46 Conductors 3 and 6 in the area of section 49. Die Formations 43, 46 are only provided by the insulator 40 separately, opposite the formations 42, 45, 44, 48 and arranged mutually parallel.

Fig. 4a zeigt in einer Aufsicht das Ende des Steckers 83 mit den acht gegenseitig parallel verlaufenden Kontaktstellen 83b, welche sich über eine Länge 83a erstrecken. In Fig. 4b ist der Verlauf der Leiterbahnen 1-8 in einer Ebene abgewickelt dargestellt, woraus insbesondere die Überkreuzungen der Leiterbahnen 1-8 im Steckverbindungsteil 80 ersichtlich sind. Der sehr kurz ausgestaltete Kontaktfedernabschnitt 19 mündet in den Überkreuzungsabschnitt 39, in welchem sich die Leiterbahnen 1,2; 4,5 und 7,8 gegenseitig überkreuzen. Die Leiterbahnen 1-8 verlaufen im Abschnitt 49 im wesentlichen gegenseitig parallel, und, wie in den Figuren 2, 3 und 6 dargestellt, in zwei gegenseitig beabstandeten Ebenen. Nach dem Überkreuzungsabschnitt 69 enden die Leiterbahnen 1-8 im Schneidklemmenbereich 79. Die Abschnitte 39, 49 und 69 bilden zusammen einen Kompensationsabschnitt 99, innerhalb welchem eine gezielte Übersprechkompensation erzeugt wird. 4a shows a top view of the end of the plug 83 with the eight mutually parallel contact points 83b, which extend over a length 83a. 4b the course of the conductor tracks 1-8 is in one Planned level, from which in particular the Crossings of conductor tracks 1-8 in the connector part 80 can be seen. The very short designed contact spring section 19 opens into the Crossover section 39, in which the conductor tracks 1.2; 4.5 and 7.8 cross each other. The conductor tracks 1-8 run in section 49 in essentially mutually parallel, and, as in the figures 2, 3 and 6 shown in two mutually spaced Levels. After the crossover section 69, the ends Conductor tracks 1-8 in the insulation displacement area 79. Die Sections 39, 49 and 69 together form one Compensation section 99, within which a targeted Crosstalk compensation is generated.

Fig. 6 zeigt schematisch eine Seitenansicht der Buchse 85 mit erstem Teilgehäuse 85a und zweitem Teilgehäuse 85b. Alle Kontaktfedern 11-18 verlaufen in derselben Ebene, wobei nur die Kontaktfeder 11 mit Kontaktstelle 11a bezeichnet ist. An der Umlenkstelle 29 ändert der Verlauf der Leiterbahnen 1-8 bezüglich der Ausrichtung der Kontaktfedern 11-18 um etwa 90 Grad. Die Leiterbahnen 1-8 verlaufen danach in zwei parallelen Ebenen, wobei in der einen Ebene die Leiterbahnabschnitte 41,42 und in der anderen Ebene der Leiterbahnabschnitt 43 dargestellt ist. Zwischen diesen beiden Ebenen ist der Isolator 40 angeordnet. Dieser als Dielektrikum dienende Isolator 40 kann beispielsweise als Folie, insbesondere als PET-Folie ausgestaltet sein. Die Folie weist in einer bevorzugten Ausführungsform eine Dicke von weniger als 0.3 mm auf.6 schematically shows a side view of the socket 85 with first partial housing 85a and second partial housing 85b. All contact springs 11-18 run in the same plane, whereby only the contact spring 11 with contact point 11a is designated. The course changes at the deflection point 29 of the conductor tracks 1-8 with respect to the alignment of the Contact springs 11-18 about 90 degrees. The conductor tracks 1-8 then run in two parallel planes, with the one level the conductor track sections 41, 42 and in the another level of the conductor track section 43 is shown. The isolator 40 is between these two levels arranged. This insulator 40, which serves as a dielectric can for example as a film, in particular as a PET film be designed. The film has a preferred Embodiment has a thickness of less than 0.3 mm.

Fig. 5 zeigt die perspektivische Ansicht eines zweiten Teilgehäuses 85b mit Teilgehäusewand 85e und Frontwand 85f, wobei in diesem Teilgehäuse 85b das Steckverbindungsteil 80 angeordnet ist. Die Leiter 1-8 sind im Umlenkungsabschnitt 29 zwischen den Halterungen 85d des zweiten Teilgehäuses 85b gehalten. Der Isolator 40 liegt auf der Frontwand 85f auf. Das Teilgehäuse 85b ist, wie in Fig. 6 dargestellt, zusammen mit dem ersten Teilgehäuse 85a zu einer Buchse 85 zusammenbaubar. Da der Abschnitt 49 beziehungsweise der Kompensationsabschnitt 99 im wesentlichen senkrecht zur Längsrichtung der Buchse 85 verlaufend angeordnet ist, ist die Buche 85 in Längsrichtung sehr kurz und kompakt ausgestaltet. Da der Abschnitt 49 beziehungsweise der Kompensationsabschnitt 99 bezüglich der Längsrichtung der Buchse 85 etwa in deren Mitte angeordnet ist, wird die elektrische Kompensation unempfindlich gegenüber metallischen Schirmflächen, welche zur Nutzung des Faraday-Effektes aussen an die Buchse 85 angebracht werden können. Dies ergibt den Vorteil, dass dasselbe Steckverbindungsteil 80 sowohl für geschirmte wie auch für ungeschirmte Stecksysteme verwendbar ist.Fig. 5 shows the perspective view of a second Part housing 85b with part housing wall 85e and front wall 85f, in this part housing 85b the connector part 80 is arranged. The heads 1-8 are in Deflection section 29 between the brackets 85d of the held second sub-housing 85b. The insulator 40 is located on the front wall 85f. The sub-case 85b is as in Fig. 6, together with the first sub-housing 85a can be assembled into a socket 85. Since section 49 or the compensation section 99 essentially perpendicular to the longitudinal direction of the socket 85 is arranged, the beech 85 is in the longitudinal direction very short and compact. Since section 49 or the compensation section 99 with respect the longitudinal direction of the socket 85 approximately in the middle is arranged, the electrical compensation insensitive to metallic screen surfaces, which to use the Faraday effect on socket 85 can be attached. This gives the advantage that the same connector 80 for both shielded can also be used for unshielded connector systems.

An Stelle der Schneidklemmen können als Ausgangskontakte 71-78 auch Lötpin vorgesehen sein.Instead of the insulation displacement terminals can be used as output contacts 71-78 solder pin can also be provided.

In einer weiteren Ausführungsform kann auf den Überkreuzungsabschnitt 69 verzichtet werden, sodass das Steckverbindungsteil 80 nur im Überkreuzungsabschnitt 39 sich überkreuzende Leiterbahnen 1-8 aufweist.In a further embodiment, the crossover section 69 are waived, so that Plug connection part 80 only in the crossover section 39 crossing conductor tracks 1-8.

In einer weiteren Ausführungsform könnten die Leiterbahnen 1-8 derart ausgeformt sein, dass diese in der Seitenansicht gemäss Fig. 6 einen im wesentlichen Z-förmigen Verlauf aufweisen.In a further embodiment, the conductor tracks could 1-8 be shaped in such a way that these are viewed from the side 6 an essentially Z-shaped Show course.
