Description

Die Erfindung betrifft einen elektrischen Verbinder für die Datentechnik, insbesondere einen RJ45-Stecker, mit mehreren, im wesentlichen parallel zueinander angeordneten, einstückigen Kontakten mit Anschlussabschnitten für Kabeladern, Kontaktabschnitten für den Eingriff mit Kontaktabschnitten eines weiteren Verbinders sowie plattenförmigen Befestigungsabschnitten, an deren Unterseite die Anschlussabschnitte angeordnet sind, wobei die plattenförmigen Befestigungsabschnitte wenigstens eines ersten Kontaktpaares an ihrer Oberseite Kontaktabschnitte aufweisen und fluchtend zueinander angeordnet sind.The invention relates to an electrical connector for data technology, in particular a RJ45 plug, with a plurality of substantially parallel, one-piece contacts with cable conductor connecting sections, contact sections for engagement with contact sections of another connector and plate-shaped mounting sections, on the underside of the connection sections are arranged, wherein the plate-shaped fastening portions of at least one first pair of contacts on its upper side contact portions and are arranged in alignment with each other.

Gattungsgemäße RJ45-Stecker sind weit verbreitet und zeichnen sich durch kostengünstige Herstellbarkeit aus. Die einstückigen Kontakte sind insgesamt plattenförmig und nebeneinander fluchtend angeordnet. An der Unterseite tragen die Kontakte selbstschneidende Anschlussklemmen und an ihrer Oberseite gerundete Kontaktflächen. Gattungsgemäße RJ45-Stecker sind für höhere Übertragungsfrequenzen aufgrund des zu hohen Nahnebensprechens nicht geeignetGeneric RJ45 plugs are widely used and are characterized by cost manufacturability. The one-piece contacts are overall plate-shaped and arranged side by side in alignment. At the bottom, the contacts carry self-tapping terminals and rounded at the top contact surfaces. Generic RJ45 plugs are not suitable for higher transmission frequencies due to the excessive near-end crosstalk

Aus der internationalen Patentanmeldung WO 99/23 729 A ist weiterhin ein elektrischer Steckverbinder bekannt, in dessen Stecker acht Kontakte angeordnet sind, die parallel zueinander verlaufen und zu Kontaktpaaren zusammengefasst sind. An den Kontakten sind Abschnitte für den Anschluss von Kabeladern und Abschnitte für den Eingriff mit Kontakten einer Buchse vorgesehen. Die Abschnitte für den Eingriff mit Kontakten einer Buchse sind plattenförmig ausgebildet und weisen an der Seite, die den Kontakten einer Buchse zugewandt sind, Kontaktabschnitte auf. Die Kontaktabschnitte von jeweils zwei Kontaktpaaren sind in die gleiche Richtung und die Kontaktabschnitte der anderen Kontaktpaare sind in die entgegengesetzte Richtungen weisend ausgerichtet.International patent application WO 99/23 729 A further discloses an electrical connector in whose plug eight contacts are arranged, which run parallel to one another and are combined to form contact pairs. Sections for connecting cable cores and sections for engaging contacts of a socket are provided on the contacts. The portions for engagement with contacts of a socket are plate-shaped and have on the side facing the contacts of a socket, contact portions. The contact portions of each pair of contact pairs are in the same direction and the contact portions of the other pairs of contacts are oriented in the opposite directions.

Mit der Erfindung soll ein elektrischer Verbinder für die Datentechnik geschaffen werden, bei dem das Übersprechen zwischen den Kontakten verringert ist.With the invention, an electrical connector for the data technology is to be created, in which the cross-talk between the contacts is reduced.

Erfindungsgemäß ist hierzu ein elektrischer Verbinder für die Datentechnik, insbesondere ein RJ45-Stecker, mit mehreren, im wesentlichen parallel zueinander angeordneten, einstückigen Kontakten mit Anschlussabschnitten für Kabeladern, Kontaktabschnitten für den Eingriff mit Kontaktabschnitten eines weiteren Verbinders sowie plattenförmigen Befestigungsabschnitten, an deren Unterseite die Anschlussabschnitte angeordnet sind, vorgesehen, wobei die plattenförmigen Befestigungsabschnitte wenigstens eines ersten Kontaktpaares an ihrer Oberseite Kontaktabschnitte aufweisen und fluchtend zueinander angeordnet sind, bei dem die plattenförmigen Befestigungsabschnitte wenigstens eines zweiten Kontaktpaares gegenüber den plattenförmigen Befestigungsabschnitten des wenigstens einen ersten Kontaktpaares in einer parallel zu den plattenförmigen Befestigungsabschnitten verlaufenden Richtung versetzt angeordnet sind.According to the invention for this purpose, an electrical connector for data technology, in particular a RJ45 connector, with a plurality of substantially mutually parallel, one-piece contacts with connection sections for cable cores, contact portions for engagement with contact portions of another connector and plate-shaped mounting portions, on the underside of the terminal portions are arranged, wherein the plate-shaped fixing portions of at least a first pair of contacts on its upper side contact portions and are arranged in alignment with each other, wherein the plate-shaped mounting portions of at least one second contact pair with respect to the plate-shaped mounting portions of the at least one first pair of contacts in a plane parallel to the plate-shaped mounting portions Direction are arranged offset.

Durch die versetzte Anordnung der plattenförmigen Befestigungsabschnitte kann eine Überdeckung dieser Befestigungsabschnitte und damit das Übersprechen zwischen den Kontakten verringert werden. Dennoch wird durch die plattenförmigen Befestigungsabschnitte, ggf. in Verbindung mit selbstschneidenden Anschlussklemmen an der Unterseite, eine einfache und kostengünstig herstellbare Konstruktion beibehalten.Due to the staggered arrangement of the plate-shaped attachment portions, an overlap of these attachment portions and thus the crosstalk between the contacts can be reduced. Nevertheless, a simple and inexpensive to produce construction is maintained by the plate-shaped mounting portions, possibly in conjunction with self-tapping terminals on the bottom.

In Weiterbildung der Erfindung sind die plattenförmigen Befestigungsabschnitte des wenigstens einen zweiten Kontaktpaares entgegen einer Einschubrichtung des Verbinders versetzt.In a development of the invention, the plate-shaped fastening sections of the at least one second contact pair are offset against an insertion direction of the connector.

Dadurch wird eine kompakte, schmale Ausbildung des Verbinders erreicht, die insbesondere für RJ45-Stecker geeignet ist.As a result, a compact, narrow design of the connector is achieved, which is particularly suitable for RJ45 connector.

In Weiterbildung der Erfindung sind die plattenförmigen Befestigungsabschnitte des wenigstens einen zweiten Kontaktpaares gegenüber den plattenförmigen Befestigungsabschnitten des wenigstens einen ersten Kontaktpaares so weit versetzt, dass senkrecht zu den plattenförmigen Befestigungsabschnitten gesehen, sich die plattenförmigen Befestigungsabschnitte des wenigstens einen ersten Kontaktpaares und die plattenförmigen Befestigungsabschnitte des wenigstens einen zweiten Kontaktpaares nicht überdecken.In a further development of the invention, the plate-shaped mounting portions of the at least one second contact pair are offset relative to the plate-shaped mounting portions of the at least one first pair of contacts so that viewed perpendicular to the plate-shaped mounting portions, the plate-shaped mounting portions of the at least one first contact pair and the plate-shaped mounting portions of the at least one do not cover the second contact pair.

Durch diese Maßnahmen kann das Übersprechen zwischen Kontaktpaaren wesentlich verringert werden.By these measures, the crosstalk between contact pairs can be significantly reduced.

In Weiterbildung der Erfindung weisen die Kontaktabschnitte des wenigstens einen zweiten Kontaktpaares Kontaktarme auf, die sich ausgehend von den versetzten, plattenförmigen Befestigungsabschnitten in den Bereich der Kontaktabschnitte des wenigstens einen ersten Kontaktpaares erstrecken.In a development of the invention, the contact sections of the at least one second contact pair have contact arms which, starting from the offset, plate-shaped fastening sections, extend into the region of the contact sections of the at least one first contact pair.

Durch diese Maßnahmen kann eine normgerechte Anordnung der Kontaktabschnitte, insbesondere für einen RJ45-Stecker, erreicht werden. Die Kontaktarme weisen insgesamt und speziell senkrecht zu den plattenförmigen Befestigungsabschnitten eine wesentlich geringere Oberfläche auf als diese, so dass durch die Kontaktarme das Übertragungsverhalten des Verbinders nur geringfügig beeinflusst wird.By means of these measures, a standardized arrangement of the contact sections, in particular for an RJ45 plug, can be achieved. The contact arms have a total and especially perpendicular to the plate-shaped mounting portions on a much smaller surface than this, so that the transfer behavior of the connector is only slightly influenced by the contact arms.

In Weiterbildung der Erfindung ist ein Adernführungselement zum Führen von Kabeladern zu den Anschlussabschnitten der Kontakte vorgesehen, wobei eine innerhalb des Adernführungselements anzuordnende Länge der zu dem wenigstens einen zweiten Kontaktpaar geführten Kabeladern kürzer ist als eine innerhalb des Adernführungselement anzuordnende Länge der zu dem wenigstens einen ersten Kontaktpaar geführten Kabeladern.In a development of the invention, a wire guide element is provided for guiding cable wires to the terminal sections of the contacts, wherein a length of the cable wires routed within the wire guide element is shorter than a cable core to be arranged within the wire guide element Length of the cable leads routed to the at least one first contact pair.

Durch diese Maßnahmen wird der Bereich, in dem die Kabeladern unterschiedlicher Kontaktpaare in dem Adernführungselement im wesentlichen parallel verlaufen verkürzt, so dass eine weitere Verbesserung des Übersprechverhaltens erzielt wird. Das Adernführungselement kann beispielsweise aus Metall, aus metallisiertem Kunststoff oder nur aus Kunststoff bestehen. Besteht das Adernführungselement wenigstens abschnittsweise aus leitfähigem Material kann das Verhalten des Verbinders bezüglich Nahnebensprechen verbessert werden.As a result of these measures, the area in which the cable cores of different pairs of contacts in the wire guide element run substantially parallel is shortened, so that a further improvement of the crosstalk behavior is achieved. The wire guide element may for example consist of metal, of metallized plastic or only of plastic. If the wire guide element is at least partially made of conductive material, the behavior of the connector with respect to near-end crosstalk can be improved.

In Weiterbildung der Erfindung weist das Adernführungselement Mittel auf, um die zu den Anschlussabschnitten des wenigstens einen ersten Kontaktpaares geführten Kabeladern gegenüber den zu den Anschlussabschnitten des wenigstens einen zweiten Kontaktpaares geführten Kabeladern wenigstens abschnittsweise in einer Hochrichtung parallel zu den plattenförmigen Befestigungsabschnitten und senkrecht zu einer Einschubrichtung des Verbinders versetzt anzuordnen.In a development of the invention, the wire guide element has means for guiding the cable wires guided to the connection sections of the at least one first contact pair at least in sections in a vertical direction parallel to the plate-shaped fastening sections and perpendicular to an insertion direction of the cable wires routed to the connection sections of the at least one second contact pair Offset to arrange connector.

Auf diese Weise wird zwischen Kabeladern unterschiedlicher Kontaktpaare ein größerer Abstand erreicht, so dass das Übersprechverhalten verbessert wird. Durch den größeren Abstand besteht gegebenenfalls die Möglichkeit, zwischen Kabeladern von Kontaktpaaren ein Schirmblech anzuordnen.In this way, a greater distance is achieved between cable cores of different contact pairs, so that the crosstalk behavior is improved. Due to the greater distance, it may be possible to arrange a shield plate between cable cores of contact pairs.

In Weiterbildung der Erfindung sind die Anschlussabschnitte des wenigstens einen ersten Kontaktpaares gegenüber den Anschlussabschnitten des wenigstens einen zweiten Kontaktpaares in einer Hochrichtung parallel zu den plattenförmigen Befestigungsabschnitten und senkrecht zu einer Einschubrichtung des Verbinders versetzt angeordnet.In a development of the invention, the connection sections of the at least one first contact pair are arranged offset relative to the connection sections of the at least one second contact pair in a vertical direction parallel to the plate-shaped fastening sections and perpendicular to an insertion direction of the connector.

Auf diese Weise können die Kabeladern innerhalb des Verbinders geradlinig geführt werden und zwischen den Kabeladern unterschiedlicher Kontaktpaare ist der Abstand vergrößert. Gegebenenfalls kann in dem entstehenden Zwischenraum zwischen Kabeladern und Anschlussabschnitten unterschiedlicher Kontaktpaare ein Schirmblech angeordnet werden.In this way, the cable cores can be guided in a straight line within the connector and between the cable cores of different contact pairs, the distance is increased. Optionally, a shield plate can be arranged in the resulting gap between cable wires and terminal sections of different pairs of contacts.

In Weiterbildung der Erfindung weisen die plattenförmigen Befestigungsabschnitte des wenigstens einen ersten Kontaktpaares und/oder des wenigstens einen zweiten Kontaktpaares eine zentrale Ausnehmung auf.In a development of the invention, the plate-shaped fastening sections of the at least one first contact pair and / or of the at least one second contact pair have a central recess.

Durch diese Maßnahmen werden die Größe der einander gegenüberliegenden Oberflächen der Kontakte verringert, wodurch das Übertragungsverhalten verbessert wird.By these measures, the size of the opposite surfaces of the contacts are reduced, whereby the transmission behavior is improved.

In Weiterbildung der Erfindung ist ein elektrisch leitfähiges Schirmelement vorgesehen, das die im Adernführungselement anzuordnenden Kabeladern und/oder die Kontakte wenigstens abschnittsweise umgibt.In a development of the invention, an electrically conductive screen element is provided which surrounds the cable cores to be arranged in the wire guide element and / or the contacts at least in sections.

Auf diese Weise kann der Einfluss elektromagnetischer Felder auf den Verbinder verringert werden.In this way, the influence of electromagnetic fields on the connector can be reduced.

Der in der Fig. 1 dargestellte elektrische Verbinder ist als RJ45-Stecker 10 ausgebildet und weist ein aus Kunststoff bestehendes Vorderteil 12, ein Adernführungselement 14, Kontakte 16, ein elektrisch leitfähiges Schirmblech 18 sowie eine flexible Kabelführung 20 auf. In dem Adernführungselement 14 geführte Enden von Kabeladern sind lediglich abschnittsweise dargestellt. Das Vorderteil 12 weist mehrere, parallel zueinander angeordnete schlitzförmige Ausnehmungen 22 auf, in denen die plattenförmigen Kontakte 16 angeordnet und gesichert werden. Die Kontakte 16 sind jeweils paarweise zu Kontaktpaaren zusammengefasst. Das Adernführungselement 14 besteht bei der dargestellten Ausführungsform aus Kunststoff, dieses kann aber auch aus metallisiertem Kunststoff oder aus Metall bestehen, wobei dadurch das Nebensprechverfahren verbessert werden kann, aber Maßnahmen getroffen werden müssen, um Kurzschlüsse unter den Kontakten 16 zu verhindern.The electrical connector shown in FIG. 1 is designed as an RJ45 plug 10 and has a plastic front part 12, a wire guide element 14, contacts 16, an electrically conductive shield plate 18 and a flexible cable guide 20. In the wire guide element 14 guided ends of cable wires are shown only in sections. The front part 12 has a plurality of slot-shaped recesses 22 arranged parallel to one another, in which the plate-shaped contacts 16 are arranged and secured. The contacts 16 are combined in pairs to form contact pairs. The wire guide member 14 is in the illustrated embodiment of plastic, but this may also be made of metallized plastic or metal, thereby the crosstalk can be improved, but measures must be taken to prevent short circuits under the contacts 16.

In der Darstellung der Fig. 2 ist das Adernführungselement 14 mit den Kabeladern und den Kontakten 16 detaillierter dargestellt. Jeweils zwei Kontakte 16a, 16b, 16c bzw. 16d bilden jeweils ein Kontaktpaar. Die Kontakte 16a, 16b und 16c sind parallel zueinander und fluchtend angeordnet. Demgegenüber sind die Kontakte 16d mit ihren plattenförmigen Befestigungsabschnitten und Abschlussabschnitten gegenüber den Kontakten 16a, 16b und 16c entgegen einer Einschubrichtung des RJ45-Steckers 10 versetzt und weisen jeweils einen Kontaktarm 24 auf, der sich von dem plattenförmigen Befestigungsabschnitt eines Kontakts 16d in der Einschubrichtung bis in den Bereich der Kontakte 16a, 16b und 16c erstreckt. Dadurch liegen Kontaktabschnitte aller Kontakte 16a, 16b, 16c und 16d parallel und fluchtend zueinander, so dass eine normgerechte Anordnung der Kontaktabschnitte erreicht ist.In the illustration of FIG. 2, the wire guide element 14 with the cable wires and the contacts 16 is shown in more detail. Two contacts 16a, 16b, 16c and 16d each form a contact pair. The contacts 16a, 16b and 16c are arranged parallel to each other and in alignment. In contrast, the contacts 16d with their plate-shaped mounting portions and end portions relative to the contacts 16a, 16b and 16c against a direction of insertion of the RJ45 connector 10 are offset and each have a contact arm 24 which extends from the plate-shaped attachment portion of a contact 16d in the insertion direction into the region of the contacts 16a, 16b and 16c. As a result, contact portions of all contacts 16a, 16b, 16c and 16d are parallel and aligned with one another, so that a standardized arrangement of the contact portions is achieved.

Anhand der Darstellung der Fig. 4 soll der Aufbau der Kontakte 16a, 16b, 16c und 16d im einzelnen erläutert werden. Die Kontakte 16a, 16b und 16c sind identisch aufgebaut und weisen jeweils einen plattenförmigen Befestigungsabschnitt 26 auf, der mit einer zentralen Bohrung versehen ist. Durch die zentrale Bohrung werden die einander gegenüberliegenden Oberflächen der Kontakte 16a, 16b und16c verringert, wodurch sich eine verringerte Übersprechneigung ergibt. An einer Unterseite des plattenförmigen Befestigungsabschnitts 26 sind jeweils selbstscheidende Anschlussklemmen 28 angeordnet. Wird einer der Kontakte 16a, 16b, 16c auf eine Kabelader aufgesetzt, durchdringen die selbstschneidenden Anschlussklemmen 28 die Isolierung der Kabelader und stellen eine elektrische Verbindung her. An der Oberseite der plattenförmigen Befestigungsabschnitte 26 befindet sich jeweils ein Kontaktabschnitt, der durch jeweils zwei halbkreisförmige Vorsprünge 30 gebildet ist. Diese halbkreisförmigen Vorsprünge 30 sind dafür vorgesehen, mit Kontaktabschnitten einer RJ-45-Buchse einzugreifen.Based on the illustration of Fig. 4, the structure of the contacts 16a, 16b, 16c and 16d will be explained in detail. The contacts 16a, 16b and 16c are identically constructed and each have a plate-shaped mounting portion 26 which is provided with a central bore. The central bore reduces the opposing surfaces of the contacts 16a, 16b and 16c, resulting in a reduced rate of transmission. On an underside of the plate-shaped mounting portion 26 each self-separating terminals 28 are arranged. If one of the contacts 16a, 16b, 16c is placed on a cable core, the self-tapping terminals 28 penetrate the insulation of the cable core and establish an electrical connection. At the top of the plate-shaped mounting portions 26 is in each case a contact portion, which is formed by two semicircular projections 30 each. These semicircular protrusions 30 are intended to engage with contact portions of an RJ-45 jack.

Die Kontakte 16d weisen wie die Kontakte 16a, 16b und 16c einen plattenförmigen Befestigungsabschnitt 32 auf, der an seiner Unterseite selbstschneidende Anschlussklemmen 34 trägt. Der plattenförmige Befestigungsabschnitt 32 weist jedoch keine zentrale Bohrung auf. Zu beiden Seiten des plattenförmigen Befestigungsabschnitts 32 ist jeweils eine rechteckige Ausnehmung ausgeformt, die zum Befestigen der Kontakte 16d dient. An der Oberseite des plattenförmigen Befestigungsabschnitts 32 geht dieser jeweils in den Kontaktarm 24 über. Ein dem plattenförmigen Befestigungsabschnitt 32 abgewandtes Ende des Kontaktarms 24 bildet jeweils den Kontaktabschnitt der Kontakte 16d und ist fluchtend zu den halbkreisförmigen Vorsprüngen 30 der übrigen Kontakte 16a, 16b und 16c angeordnet.The contacts 16d, like the contacts 16a, 16b and 16c, have a plate-shaped fastening section 32 which carries self-tapping connection terminals 34 on its underside. However, the plate-shaped attachment portion 32 has no central bore. On both sides of the plate-shaped mounting portion 32, a rectangular recess is formed in each case, which serves for fastening the contacts 16d. At the top of the plate-shaped mounting portion 32 of this goes in each case in the contact arm 24. A the plate-shaped mounting portion 32 remote from the end of the contact arm 24 respectively forms the contact portion of the contacts 16d and is aligned with the semicircular protrusions 30 of the remaining contacts 16a, 16b and 16c.

Wie in der Fig. 4 zu erkennen ist, weisen die Kontaktarme 24 gegenüber den Kontakten 16a, 16b und 16c eine wesentlich geringere Oberfläche auf. Dies gilt speziell für die parallel zu den plattenförmigen Befestigungsabschnitten 26 angeordneten Flächen der Kontaktarme 24. Dadurch ist eine Übersprechneigung zwischen den Kontakten 16d und den Kontakten 16a, 16b und 16c deutlich verringert. Darüber hinaus ist auch eine Übersprechneigung zwischen den Kontakten 16a, 16b und 16c verringert, da sich zwischen den Kontakten 16a, 16b und 16c der jeweiligen Kontaktpaare gegenüber konventionellen R45-Steckern ein vergleichsweise großer Zwischenraum befindet.As can be seen in FIG. 4, the contact arms 24 have a substantially smaller surface area than the contacts 16a, 16b and 16c. This applies in particular to the surfaces of the contact arms 24 which are arranged parallel to the plate-shaped fastening sections 26. As a result, a superposition tendency between the contacts 16d and the contacts 16a, 16b and 16c is markedly reduced. In addition, a Überspäubeigung between the contacts 16a, 16b and 16c is reduced because there is a comparatively large gap between the contacts 16a, 16b and 16c of the respective contact pairs compared to conventional R45 plugs.

Unter erneuter Bezugnahme auf die Fig. 2 ist zu erkennen, dass Kabelführungskanäle in dem Adernführungselement 14 so angeordnet sind, dass Kabeladern 36, die zu den Anschlussabschnitten der Kontakte 16d führen, gegenüber den Kabeladern 38, 40 und 42, die zu den Anschlussabschnitten der Kontakte 16a, 16b bzw. 16c führen, in einer Hochrichtung des Verbinders 10 versetzt sind. In dieser, parallel zu den Kontakten 16a, 16b und 16c und senkrecht zur Einschubrichtung des RJ45-Steckers 10 verlaufenden Richtung liegt somit ein Zwischenraum zwischen den Kabeladern 36 der Kontakte 16d und den Kabeladern 38, 40 und 42 der Kontakte 16a, 16b und 16c. Gleichzeitig liegt in einer Querrichtung des RJ45-Steckers 10 ein vergleichsweise großer Zwischenraum zwischen den Kabeladern 38, 40 und 42 der jeweiligen Kontaktpaare. Dadurch ist eine Übersprechneigung zwischen den Kabeladern 36, 38, 40 und 42 der jeweiligen Kontaktpaare verringert.Referring again to FIG. 2, it can be seen that cable routing channels are disposed in the wire guide member 14 such that cable wires 36 leading to the terminal portions of the contacts 16d face the cable wires 38, 40 and 42 leading to the terminal portions of the contacts 16a, 16b and 16c, are offset in a vertical direction of the connector 10. In this, parallel to the contacts 16a, 16b and 16c and perpendicular to the direction of insertion of the RJ45 connector 10 extending direction is thus a gap between the cable cores 36 of the contacts 16d and the cable cores 38, 40 and 42 of the contacts 16a, 16b and 16c. At the same time, in a transverse direction of the RJ45 plug 10, there is a comparatively large gap between the cable cores 38, 40 and 42 of the respective contact pairs. As a result, a Überspäubeigung between the cable cores 36, 38, 40 and 42 of the respective contact pairs is reduced.

Darüber hinaus ist die in dem Adernführungselement 14 angeordnete Länge der Kabeladern 36 gegenüber der in dem Adernführungselement 14 angeordneten Länge der Kabeladern 38, 40 bzw. 42 verringert, da die Anschlussabschnitte der Kontakte 16d gegenüber den Anschlussabschnitten der Kontakte 16a, 16b und 16c entgegen der Einschubrichtung versetzt sind. Dadurch ist die Übersprechneigung zwischen den Kabeladern 36 und den Kabeladern 38, 40 bzw. 42 verringert.In addition, the arranged in the wire guide element 14 length of the cable wires 36 is opposite to that in the wire guide element 14 arranged length of the cable cores 38, 40 and 42 reduced because the terminal portions of the contacts 16 d relative to the terminal portions of the contacts 16 a, 16 b and 16 c are offset against the insertion direction. As a result, the Überspäubeigung between the cable cores 36 and the cable cores 38, 40 and 42 is reduced.

Die plattenförmigen Befestigungsabschnitte 32 der Kontakte 16d sind dabei entgegen der Einschubrichtung so weit gegenüber den Befestigungsabschnitten 26 der Kontakte 16a, 16b und 16c versetzt, dass in einer Querrichtung des RJ45-Steckers 10 keine Überdeckung zwischen den Befestigungsabschnitten 32 mit den Anschlussabschnitten 34 und den Befestigungsabschnitten 26 mit den Anschlussabschnitten 28 sowie den Kontaktabschnitten 30 vorliegt.The plate-shaped attachment portions 32 of the contacts 16d are opposite to the insertion direction so far opposite the attachment portions 26 of the contacts 16a, 16b and 16c offset that in a transverse direction of the RJ45 connector 10 no overlap between the attachment portions 32 with the terminal portions 34 and the attachment portions 26th is present with the connection sections 28 and the contact sections 30.

In der Darstellung der Fig. 3 ist die in der Hochrichtung versetzte Anordnung der Kabeladern 36 und der Kabeladern 38, 40 und 42 gut zu erkennen. Dadurch entsteht zwischen diesen Kabeladerpaaren 36, 38, 40 und 42 jeweils ein Zwischenraum, der zu einer Verringerung der Übersprechneigung beiträgt. Das Adernführungselement 14 weist in diesen Zwischenräumen Zwischenwände auf.In the illustration of FIG. 3, the staggered in the vertical direction arrangement of the cable cores 36 and the cable cores 38, 40 and 42 is clearly visible. This results in a space between these pairs of cable cores 36, 38, 40 and 42, which contributes to a reduction in the tendency to overspill. The wire guide element 14 has intermediate walls in these intermediate spaces.
