- the wires can also have multiple strands, which follow - without limitation thereto-always only ladders is mentioned; this should therefore always include strands.
- Electrical connectors can be either ready to assemble or ready wired, in which case the contact carrier and the cable are usually encapsulated by the handle body.
- the handle body itself can be made by molding the contact carrier.
- the electrical and mechanical connection of the individual wires or conductors of a cable to the individual contact elements takes place in particular by means of a solder connection or by a crimp connection.
- the stripped end of a wire is inserted axially into a corresponding ferrule (crimp barrel) or sleeve-shaped end portion of the contact element and then electrically and mechanically connected to the crimp barrel or contact element by mechanical compression of the crimp barrel or sleeve-shaped end portion.
- crimping standardized in DIN EN 60352-2 a solderless electrical connection is made, wherein the crimped connection can be made both by Handcrimpwerkmaschinee and by means of semi or fully automatic crimping machines.
- the stripping of the wires and the crimping of the contact elements can be carried out by machine in one operation, so that the crimping technique has largely superseded the soldering in the background.

- the present invention is therefore the object of further developing an electrical connector described above to the effect that the assembly of the connector, in particular the mounting of the contact elements in the contact carrier is easier.
- the invention has for its object to provide an electrical connector that is particularly well suited for the signal and data transmission in the harsh industrial environment with a compact design possible.

- a contact element with its end facing away from the connected conductor can be simply inserted through the through hole in the end face of the contact carrier, wherein the contact element when passing through the through hole may have an angle to the longitudinal axis of the contact carrier greater than zero.
- the free end of the contact element can thus be pushed "obliquely from the side" through the through hole and only then be pivoted into the corresponding groove.
- US 2008/0287000 A1 shows an opening with funnel-shaped portion, wherein the inner diameter of the funnel-shaped portion to the counterpart connector facing side decreases.
- the through-holes in the end face of the contact carrier are funnel-shaped, with the inner diameter of the through-holes increasing from the side facing the grooves to the side facing the mating connector.
- the funnel-shaped formation of the through holes facilitates the inclination of the contact elements when inserted into the through holes.
- the insertion and pivoting of the contact elements is further facilitated if the funnel shape of the through holes is aligned concentrically with the preferred insertion direction of the contact elements.
- the through holes may be formed so that they have at their narrowest point a slightly larger diameter than the ends of the contact elements fürzusteckenden.
- the individual contact elements are guided in the electrical connector according to the invention only in a relatively small portion of their total length in a through hole, while the free end protrudes from the through hole and the wires facing the end is arranged in the mounted state in the outwardly open groove.
- the axial alignment of the contact elements is less well secured than in conventional contact carriers, in which the length of the through holes corresponds to the length of the contact carrier.

- the inventive design of the contact carrier is particularly advantageous in such connectors, which have a larger number of contact elements, in particular for connectors that are used to connect cables with four wire pairs and thus have eight contact elements.
- the contact carrier consists of four contact carrier parts, each having a quarter-circle-shaped base. If the connector is provided for connecting four pairs of wires, then two grooves are formed in each contact carrier part and two through holes are correspondingly formed in the end side of each contact carrier part facing the mating connector. The two wires of a pair of wires, which are preferably twisted together, are thus connected to two contact elements, which are arranged after assembly in a contact carrier part.
- the sleeve and the shielding element are preferably made of metal.
- the sleeve and the shielding element are preferably formed integrally.
- the cross-shaped shielding element protrudes on the side facing the cable out of the sleeve, so that the metallic shields of the individual twisted pairs of wires (PiMF) can be attached to the protruding end of the Schirmungselements, whereby the shield between the individual pairs of wires further improved and thus further reducing the likelihood of crosstalk from one wire pair to another wire pair.
- the metallic shields of the individual twisted pairs of wires Pieris
- a stop for the contact carrier parts is preferably formed on the inner circumference of the sleeve. After inserting the contact elements in the individual contact carrier parts, these can thus be easily inserted into the chambers formed by the sleeve and the cross-shaped shielding element.

- the suitability of the connector for the signal and data transmission, in particular for Ethernet applications is thereby improved in a simple manner that the mating contact elements of the mating connector a in the axial direction extending portion in which the outer diameter is reduced for impedance matching.
- return loss is essentially determined by the homogeneity of the characteristic impedance. Occurs in propagation direction of the electromagnetic wave an impedance jump, this leads to reflections that can be superimposed with the useful signals to be transmitted, so that it may be due to interference to the partial extinction of the useful signal to be transmitted.
- the contact elements of the connector and the differential longitudinal impedance of the mating contact elements of the mating connector can be largely reduced, that the mating contact elements have a region extending in the axial direction, in which the outer diameter - compared to the outer diameter in the other areas of the mating contact element - is reduced.
- the differential longitudinal impedance depends on the ratio of the diameter of a contact element or mating contact element to the center distance to adjacent contact elements or mating contact elements
- the differential longitudinal impedance of the mating contact elements by changing the diameter of the mating contact elements can be adjusted so that the differential longitudinal impedance of the mating contact elements approximately a predetermined setpoint, for example, corresponds to 100 ohms.
- the counter contact elements facing the end of the contact elements pin-shaped and the contact elements facing the end of the mating contact elements is hollow, so that the pin-shaped ends of the contact elements can be inserted into the hollow ends of the mating contact elements. If the ends of the mating contact elements facing away from the contact elements are pin-shaped, the mating contact elements can simply be connected to a circuit board on the device side, for example by wave soldering.
- the mating contact carrier of the mating connector according to an embodiment of four mating contact carrier parts, each having a quarter-circle base, wherein in each mating contact carrier part at least one longitudinally extending bore for Recording a mating contact element is arranged.
- the four mating contact carrier parts are arranged by an inside of the outer sleeve, Shielded in the longitudinal direction of the outer sleeve and the mating contact carrier extending cross-shaped shielding element against each other.

- both the mating connector and the connector has a cross-shaped shielding element
- the extensions and the counter-extensions are arranged and formed so that they overlap in the axial direction when the connector and the mating connector are connected together.
- the inventive method is in an electrical connector in which the wires facing the end of the contact elements is hollow, characterized by machine particularly easy to carry out that the individual stripped ends of the wires inserted into the hollow ends of the contact elements and by mechanical compression (crimping) the ends of the individual wires are electrically connected to the individual contact elements.
- a contact element inserted into the hollow end of the core can be inserted into the receptacle of a corresponding pressing jaw and then pressed together by depressing a counter-jaw, the contact element in the region of the inserted wire, whereby the stripped end of the wire is electrically and mechanically firmly connected to the contact element ,
- the contact carrier or the contact carrier parts is preferably inserted into a cylindrical sleeve with a disposed within the sleeve, extending in the longitudinal direction of the sleeve cross-shaped shielding element. Thereafter, the sleeve-like threaded portion is pushed onto the sleeve and then encapsulated with the contact elements connected to the wires and the contact carrier part or the contact carrier parts for producing a handle body.
- the Fig. 1 to 3 show an electrical connector 1 as part of a total in the Fig. 8 and 9 illustrated electrical connector, wherein the electrical Connector 1 for releasably connecting a cable with a in the 10 to 12 shown mating connector 2 is used.

- both the external thread 8 of the cap screw 7 and the internal thread 10 of the outer sleeve 9 are partially interrupted, that is, both the external thread 8 and the internal thread 10 have a plurality provided in plug or screw thread-free areas.
- the contact carrier 6 consists of four separate contact carrier parts 61, 62, 63, 64, each having a quarter-circle-shaped base.

Since the electrical connector 1 shown in the figures has a total of eight contact elements 5, thus eight grooves 11 and eight through holes 13 are formed in the contact carrier 6 in total.
- a contact element 5 is thereby particularly easy in the contact carrier 6 and a contact carrier part 61 are mounted that initially the free, pin-shaped end 14 at an angle to the longitudinal axis the contact carrier part 61 is greater than zero, ie obliquely from the side through the through hole 13 is inserted ( Fig. 6a and 7a ). Only then is the contact element 5 aligned in the longitudinal direction of the contact carrier part 61 by the wires 3 facing the hollow end 15 of the contact element 5 is pivoted or pressed into the groove 11.

- the cylindrical sleeve 19 with the arranged therein, integrally connected to the sleeve 19 cross-shaped Schirmungselement 20 serves to receive the individual contact carrier parts 61, 62, 63, 64 with the contact elements 5 arranged therein.
- the cross-shaped shielding element 20 thus the individual contact carrier parts 61, 62, 63, 64 and thus arranged in the contact carrier parts 61, 62, 63, 64 contact elements 5 are separated from each other, so that a crosstalk between one, a contact carrier member 61 associated shielded wire pair and another, a second Contact support member 62 associated shielded wire pair is largely prevented.
- the further shielding sleeve 21 By arranging the further shielding sleeve 21 on the opposite side of the mating connector 2 of the electrical connector 1, which is arranged in the handle body 4 produced by molding, the individual wires 3 and the individual wire pairs are additionally shielded.

- the mating contact elements 22 have a central region 24, in which the outer diameter - compared to the outer diameter of the remaining regions of the mating contact elements 22 - is reduced.
- the reduction of the outer diameter of the contact elements 22 in the central region 24 serves to adapt the differential longitudinal impedance of the mating contact elements 22, whereby an impedance jump in the longitudinal direction of the electrical connector should be avoided. Since the differential longitudinal impedance of the individual mating contact elements 22 depends inter alia on their outer diameter and the center distance of the mating contact elements 22 to each other, an impedance matching can be achieved by reducing the outer diameter in the central region 24 of the mating contact elements 22, without the arrangement of the individual mating contact elements 22 are changed got to.
- the contact elements 5 of the electrical connector 1 facing the end 25 of the mating contact elements 22 is hollow, so that the pin-shaped ends 14 of the contact elements 5 can be inserted into the hollow ends 25 of the mating contact elements 22.

- the mating connector 2 also has a cross-shaped shielding element 29, by which the individual mating contact carrier parts 71, 72, 73, 74 and thus the mating contact elements 22 disposed therein are shielded from each other.
- the cross-shaped shielding element 29 of the mating connector 2 on the side facing away from the connector 1 has an annular portion 30 which abuts in the mounted state on the end face of the outer sleeve 9.
- four pins 31 are arranged, by means of which the mating connector 2 can be mounted on a circuit board.
- a coding is formed between the connector 1 and the mating connector 2, so that the connector 1 and the mating connector 2 can be screwed together only in a certain orientation to each other.

Description
Die Erfindung betrifft einen elektrischen Steckverbinder zum lösbaren Verbinden eines mehradrigen Kabels mit einem Gegensteckverbinder, mit einem das Kabel bzw. die Adern des Kabels umgebenden Griffkörper, mit einem eine Mehrzahl von Kontaktelementen aufnehmenden bzw. haltenden Kontaktträger und mit einem drehbar angeordneten hülsenförmigen Gewindeteil, wobei die einzelnen Kontaktelemente elektrisch leitend mit den einzelnen Adern verbunden sind und wobei das hülsenförmige Gewindeteil mit einem korrespondierenden hülsenförmigen Gewindeteil des Gegensteckverbinders verschraubbar ist, nach dem Oberbegriff des Anspruchs 1. Ein solcher Steckverbinder ist aus der
Elektrische Steckverbindungen bestehen im wesentlichen aus zwei Teilen, dem elektrischen Steckverbinder und dem Gegensteckverbinder. Sowohl der Steckverbinder als auch der Gegensteckverbinder weisen jeweils einen Kontaktträger mit einer Mehrzahl von Kontakten auf, bei denen es sich entweder um Kontaktstifte oder um korrespondierende Kontaktbuchsen handelt. In Abhängigkeit davon, ob in dem jeweiligen Kontaktträger die Kontaktstifte oder die Kontaktbuchsen angeordnet sind, wird das zugehörige Verbindungsteil auch als Stecker oder als Buchse bezeichnet. In der Praxis ist es zumeist so, dass der Steckverbinder, dessen Kontaktträger die Kontaktstifte aufweist, d. h. der Stecker, eine Überwurfschraube mit einem Außengewinde als hülsenförmiges Gewindeteil und der Steckverbinder, in dessen Kontaktträger die Kontaktbuchsen angeordnet sind, d. h. die Buchse, eine Außenhülse mit einem Innengewinde aufweist. Werden mit der Steckverbindung zwei Kabel miteinander verbunden, so ist die Außenhülse der Buchse als eine Art Überwurfmutter ausgebildet.Electrical connectors consist essentially of two parts, the electrical connector and the mating connector. Both the connector and the mating connector each have a contact carrier with a plurality of contacts, which are either contact pins or corresponding contact sockets. Depending on whether the contact pins or the contact sockets are arranged in the respective contact carrier, the associated connecting part is also referred to as a plug or socket. In practice, it is usually the case that the connector whose contact carrier has the contact pins, ie the plug, a cap screw with an external thread as a sleeve-shaped threaded portion and the connector in the contact carrier, the contact sockets are arranged, ie the socket, an outer sleeve with a Internal thread has. If two cables are connected to one another with the plug connection, then the outer sleeve of the bushing is designed as a kind of union nut.
Derartige elektrische Steckverbindungen bzw. Steckverbinder werden als Industriestecker in der Automatisierungstechnik sowohl in Schaltschränken als auch bei Feldgeräten in unterschiedlichen Ausführungsformen eingesetzt. Weite Verbreitung haben insbesondere die Bauformen M8 und M12 mit 4, 5, 6 oder auch 8 Kontakten gefunden. Die Steckverbinder dienen zum Anschluss von Anschlusskabeln mit einer entsprechenden Anzahl an Adern, wobei die einzelnen Adern jeweils aus einem Leiter und einer den Leiter umgebenden Aderisolation bestehen und gemeinsam von einer Kabelisolation umgeben sind. Anstelle eines massiven Leiters können die Adern auch mehrere Litzen aufweisen, wobei nachfolgen - ohne Einschränkung hierauf-stets nur von Leitern die Rede ist; dies soll somit stets auch Litzen umfassen.Such electrical connectors or connectors are used as industrial plugs in automation technology both in cabinets and field devices in different embodiments. The types M8 and M12 with 4, 5, 6 or even 8 contacts have found widespread use. The connectors are used to connect connection cables with a corresponding number of cores, whereby the individual cores each consist of a conductor and a core insulation surrounding the conductor and are jointly surrounded by a cable insulation. Instead of a solid conductor, the wires can also have multiple strands, which follow - without limitation thereto-always only ladders is mentioned; this should therefore always include strands.
Elektrische Steckverbinder können entweder frei konfektionierbar oder bereits fertig verdrahtet sein, wobei dann der Kontaktträger und das Kabel in der Regel von dem Griffkörper umspritzt sind. Dabei kann auch der Griffkörper selber durch Umspritzen der Kontaktträger hergestellt werden.Electrical connectors can be either ready to assemble or ready wired, in which case the contact carrier and the cable are usually encapsulated by the handle body. In this case, the handle body itself can be made by molding the contact carrier.
Bei einem vom Verbraucher nicht frei konfektionierbaren Steckverbinder erfolgt die elektrische und mechanische Verbindung der einzelnen Adern bzw. Leiter eines Kabels mit den einzelnen Kontaktelementen insbesondere durch eine Lötverbindung oder durch eine Crimpverbindung. Bei der Crimp-Anschlusstechnik wird das abisolierte Ende einer Ader in eine entsprechende Anschlußhülse (Crimphülse) oder einen hülsenförmigen Endabschnitt des Kontaktelements axial eingeführt und anschließend durch mechanisches Zusammendrücken der Crimphülse bzw. des hülsenförmigen Endabschnitts elektrisch und mechanisch mit der Crimphülse bzw. dem Kontaktelement verbunden. Durch das in DIN EN 60352-2 genormte Crimpen erfolgt eine lötfreie elektrische Verbindung, wobei die Crimpverbindung sowohl durch Handcrimpwerkzeuge als auch mittels halb- oder vollautomatischer Crimpmaschinen hergestellt werden kann. Das Abisolieren der Adern und das Crimpen der Kontaktelemente lässt sich maschinell in einem Arbeitsgang durchführen, so dass die Crimptechnik das Löten weitgehend in den Hintergrund verdrängt hat.In the case of a connector which can not be freely assembled by the consumer, the electrical and mechanical connection of the individual wires or conductors of a cable to the individual contact elements takes place in particular by means of a solder connection or by a crimp connection. In the crimp termination technique, the stripped end of a wire is inserted axially into a corresponding ferrule (crimp barrel) or sleeve-shaped end portion of the contact element and then electrically and mechanically connected to the crimp barrel or contact element by mechanical compression of the crimp barrel or sleeve-shaped end portion. By crimping standardized in DIN EN 60352-2 a solderless electrical connection is made, wherein the crimped connection can be made both by Handcrimpwerkzeuge and by means of semi or fully automatic crimping machines. The stripping of the wires and the crimping of the contact elements can be carried out by machine in one operation, so that the crimping technique has largely superseded the soldering in the background.
Elektrische Steckverbindungen sind Schnittstellen, die elektrische Signale oder Leistungen übertragen, wobei die Steckverbindungen bzw. Steckverbinder je nach Anwendungsfall unterschiedliche Anforderungen erfühlen müssen. Bei Steckverbindern, die in der Signal- und Datentechnik eingesetzt werden, insbesondere bei solchen Steckverbindern, die innerhalb von Netzwerken und Feldbussen eingesetzt werden, müssen entsprechend der Datenübertragungsrate des jeweiligen Netzwerks bzw. Feldbusses gewisse hochfrequente Randbedingungen berücksichtigt werden, um ein einwandfreies Übertragen der Signale und Daten zu gewährleisten.Electrical connectors are interfaces that transmit electrical signals or power, the connectors or connectors need to feel different requirements depending on the application. In the case of connectors used in signal and data technology, in particular in the case of connectors which are used within networks and fieldbuses, In accordance with the data transmission rate of the respective network or field bus, certain high-frequency boundary conditions must be taken into account in order to ensure a faultless transmission of the signals and data.
Werden Steckverbinder bzw. Steckverbindungen für die Signal- und Datentechnik nicht nur in Bürogebäuden sondern auch im rauen industriellen Umfeld eingesetzt, so müssen die Steckverbinder bzw. Steckverbindungen entsprechend robuster ausgebildet sein und eine möglichst hohe Schutzart, vorzugsweise IP67 aufweisen. Aus diesem Grund sind handelsübliche RJ45-Stecker, wie sie aus dem Bürokommunikationsbereich bekannt sind, im industriellen Bereich nur eingeschränkt einsetzbar. Daher sind Schutzgehäuse, so genannte Tüllengehäuse, entwickelt worden, die ein bereits mit einem Kabel verbundenen RJ45-Stecker aufnehmen können und dadurch den Stecker gegen äußere Einflüsse und Beschädigungen schützen. Ein entsprechendes Schutzgehäuse ist beispielsweise aus der
Um die im industriellen Bereich weit verbreiteten Steckverbinder der Bauform M12, die eine ausreichende mechanische Robustheit und Schutzklasse aufweisen, auch im Bereich der Signal- und Datentechnik, insbesondere bei Netzwerken und Feldbussen - und hier insbesondere auch für Ethernet-Anwendungen - einsetzen zu können, muss deren innerer Aufbau dahingehend modifiziert werden, dass die Anforderungen hinsichtlich der Datenübertragung erfüllt werden können. Insbesondere bei höheren Übertragungsraten sind dabei Steckverbinder mit einer größeren Anzahl an Kontakten, insbesondere mit acht Kontakten, erforderlich. Vergrößert sich die Anzahl der Kontakte, so führt dies - bei ansonsten gleich bleibendem Durchmesser des Steckverbinders - aufgrund der geringen Abmessungen zu einer aufwendigeren Montage des Steckverbinders sowie zu einem aufwendigeren Anschluss der einzelnen Adern an die einzelnen Kontaktelemente.In order to be able to use the M12 connectors, which are widely used in the industrial sector, and which have sufficient mechanical robustness and protection class, also in the area of signal and data technology, in particular for networks and field buses - and in particular also for Ethernet applications their internal structure are modified so that the requirements for data transmission can be met. In particular, at higher transmission rates while connectors with a larger number of contacts, especially with eight contacts required. Increases the number of contacts, it leads - with otherwise constant diameter of the connector - due to the small dimensions to a more complex installation of the connector and a more complex connection of the individual wires to the individual contact elements.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen eingangs beschriebenen elektrischen Steckverbinder dahingehend weiterzuentwickeln, dass die Montage des Steckverbinders, insbesondere die Montage der Kontaktelemente im Kontaktträger einfacher möglich ist. Darüber hinaus liegt der Erfindung die Aufgabe zugrunde, eine elektrische Steckverbindung anzugeben, die bei möglichst kompaktem Aufbau besonders gut für die Signal- und Datenübertragung im rauen industrielen Umfeld geeignet ist.The present invention is therefore the object of further developing an electrical connector described above to the effect that the assembly of the connector, in particular the mounting of the contact elements in the contact carrier is easier. In addition, the invention has for its object to provide an electrical connector that is particularly well suited for the signal and data transmission in the harsh industrial environment with a compact design possible.
Die zuvor genannte Aufgabe ist durch einen elektrisches Steckverbinder nach Anspruch 1 gelöst.The above object is achieved by an electrical connector according to
Durch die erfindungsgemäße Ausgestaltung des Kontaktträgers wird das Einführen der Kontaktelemente in den Kontaktträger wesentlich erleichtert. Durch die Ausbildung der nach außen offenen Nuten anstelle der ansonsten bei Kontaktträgern ausgebildeten, sich über die gesamte Länge des Kontaktträgers erstreckenden Durchgangslöcher, kann ein Kontaktelement mit seinem der angeschlossenen Ader abgewandten Ende einfach durch das Durchgangsloch in der Stirnseite des Kontaktträgers durchgesteckt werden, wobei das Kontaktelement beim Durchstecken durch das Durchgangsloch einen Winkel zur Längsachse des Kontaktträgers größer Null aufweisen kann. Das freie Ende des Kontaktelements kann somit "schräg von der Seite" durch das Durchgangsloch durchgesteckt werden und erst danach in die korrespondierende Nut eingeschwenkt werden.The inventive design of the contact carrier, the insertion of the contact elements in the contact carrier is much easier. By forming the outwardly open grooves instead of the otherwise formed in contact carriers, extending over the entire length of the contact carrier through holes, a contact element with its end facing away from the connected conductor can be simply inserted through the through hole in the end face of the contact carrier, wherein the contact element when passing through the through hole may have an angle to the longitudinal axis of the contact carrier greater than zero. The free end of the contact element can thus be pushed "obliquely from the side" through the through hole and only then be pivoted into the corresponding groove.
Diese Vorgehensweise vereinfacht das Einführen der bereits mit den Adern verbundenen Kontaktelemente in den Kontaktträger erheblich. Zum einen müssen die freien Enden der Kontaktelemente nur durch die in der Stirnseite des Kontaktträgers ausgebildeten Durchgangslöcher, deren Länge wesentlich geringer ist als die Gesamtlänge des Kontaktträgers, durchgesteckt werden. Zum anderen erleichtert die Möglichkeit des Einsteckens der Kontaktelemente "schräg von der Seite" die Montage auch einer Mehrzahl von Kontaktelementen bei einem kompakten Steckverbinder.This procedure simplifies the insertion of the already connected to the wires contact elements in the contact carrier considerably. On the one hand, the free ends of the contact elements need only be pushed through the through holes formed in the end face of the contact carrier, whose length is substantially less than the total length of the contact carrier. On the other hand, the possibility of inserting the contact elements "obliquely from the side" facilitates the assembly of a plurality of contact elements in a compact connector.
Gemäß der Erfindung sind die Durchgangslöcher in der Stirnseite des Kontaktträgers trichterförmig ausgebildet, wobei sich der Innendurchmesser der Durchgangslöcher von der den Nuten zugewandten Seite zur dem Gegensteckverbinder zugewandten Seite vergrößert. Die trichterförmige Ausbildung der Durchgangslöcher erleichtert die Schrägstellung der Kontaktelemente beim Einstecken in die Durchgangslöcher. Das Durchstecken und Einschwenken der Kontaktelemente wird dabei weiter erleichtert, wenn die Trichterform der Durchgangslöcher konzentrisch zur bevorzugten Einsteckrichtung der Kontaktelemente ausgerichtet ist. Zusätzlich können die Durchgangslöcher so ausgebildet sein, dass sie an ihrer schmalsten Stelle einen geringfügig größeren Durchmesser als die durchzusteckenden Enden der Kontaktelemente aufweisen.According to the invention, the through-holes in the end face of the contact carrier are funnel-shaped, with the inner diameter of the through-holes increasing from the side facing the grooves to the side facing the mating connector. The funnel-shaped formation of the through holes facilitates the inclination of the contact elements when inserted into the through holes. The insertion and pivoting of the contact elements is further facilitated if the funnel shape of the through holes is aligned concentrically with the preferred insertion direction of the contact elements. In addition, the through holes may be formed so that they have at their narrowest point a slightly larger diameter than the ends of the contact elements durchzusteckenden.
Die einzelnen Kontaktelemente sind bei dem erfindungsgemäßen elektrischen Steckverbinder nur in einem relativ geringen Bereich ihrer Gesamtlänge in einem Durchgangsloch geführt, während das freie Ende aus dem Durchgangsloch herausragt und das den Adern zugewandte Ende im montierten Zustand in der nach außen offenen Nut angeordnet ist. Dadurch ist die axiale Ausrichtung der Kontaktelemente weniger gut gesichert als bei herkömmlichen Kontaktträgern, bei denen die Länge der Durchgangslöcher der Länge des Kontaktträgers entspricht. Um die axiale Ausrichtung der Kontaktelemente in dem Kontaktträger besser zu gewährleisten, ist daher vorzugsweise vorgesehen, dass die Durchgangslöcher auf der dem Gegensteckverbinder zugewandten Stirnseite des Kontaktträgers jeweils von einem Kragen umgeben sind. Damit der Kragen das Einstecken des freien Endes eines Kontaktelements "schräg von der Seite" nicht behindert, weisen die Kragen auf der der Mittelachse des Steckverbinders zugewandten Seite jeweils eine Unterbrechung auf.The individual contact elements are guided in the electrical connector according to the invention only in a relatively small portion of their total length in a through hole, while the free end protrudes from the through hole and the wires facing the end is arranged in the mounted state in the outwardly open groove. As a result, the axial alignment of the contact elements is less well secured than in conventional contact carriers, in which the length of the through holes corresponds to the length of the contact carrier. In order to better ensure the axial alignment of the contact elements in the contact carrier, it is therefore preferably provided that the through-holes are each surrounded by a collar on the front side of the contact carrier facing the mating connector. Thus, the collar does not interfere with the insertion of the free end of a contact element "obliquely from the side", the collar on the side facing the central axis of the connector side each have an interruption.
Um die axiale Ausrichtung der Kontaktelemente in dem Kontaktträger besser zu gewährleisten, und um ein ungewolltes Herausschwenken der Kontaktelemente aus den Nuten zu verhindern, ist in den einzelnen Nuten vorzugsweise eine Einschnürung ausgebildet, in die die Kontaktelemente beim Einschwenken in die Nuten einrasten können. Weisen die Kontaktelemente korrespondierend zu den Nuten einen Abschnitt mit einem vergrößerten Durchmesser auf, beispielsweise ein den Adern zugewandtes hohles Ende, so kann auf einfache Art und Weise eine Verrastung zwischen der in den Nuten ausgebildeten Einschnürung und dem Abschnitt mit vergrößertem Durchmesser realisiert werden.In order to better ensure the axial alignment of the contact elements in the contact carrier, and to prevent unwanted swinging out of the contact elements from the grooves, a constriction is preferably formed in the individual grooves, in which the contact elements can engage in the grooves during pivoting. If the contact elements have a section with an enlarged diameter corresponding to the grooves, for example a hollow end facing the wires, a latching between the constriction formed in the grooves and the section with increased diameter can be realized in a simple manner.
Die zuvor beschriebene erfindungsgemäße Ausgestaltung des Kontaktträgers kann grundsätzlich bei allen Rundsteckverbindern eingesetzt werden. Besonders vorteilhaft ist die erfindungsgemäße Ausgestaltung des Kontaktträgers jedoch bei solchen Steckverbindern, die eine größere Anzahl an Kontaktelementen aufweisen, insbesondere bei Steckverbindern, die zum Anschluss von Kabeln mit vier Adernpaaren dienen und somit acht Kontaktelemente aufweisen. Bei einem derartigen Steckverbinder ist gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass der Kontaktträger aus vier Kontaktträgerteilen besteht, die jeweils eine viertelkreisförmige Grundfläche aufweisen. Ist der Steckverbinder zum Anschluss von vier Adernpaaren vorgesehen, so sind in jedem Kontaktträgerteil zwei Nuten und in der dem Gegensteckverbinder zugewandten Stirnseite jedes Kontaktträgerteils korrespondierend zwei Durchgangslöcher ausgebildet. Die beiden Adern eines Adernpaares, welche vorzugsweise miteinander verdrillt sind, werden somit mit zwei Kontaktelementen verbunden, die nach der Montage in einem Kontaktträgerteil angeordnet sind.The above-described embodiment of the contact carrier according to the invention can in principle be used in all circular connectors. However, the inventive design of the contact carrier is particularly advantageous in such connectors, which have a larger number of contact elements, in particular for connectors that are used to connect cables with four wire pairs and thus have eight contact elements. In such a connector is provided according to a further advantageous embodiment of the invention, that the contact carrier consists of four contact carrier parts, each having a quarter-circle-shaped base. If the connector is provided for connecting four pairs of wires, then two grooves are formed in each contact carrier part and two through holes are correspondingly formed in the end side of each contact carrier part facing the mating connector. The two wires of a pair of wires, which are preferably twisted together, are thus connected to two contact elements, which are arranged after assembly in a contact carrier part.
Dient der elektrische Steckverbinder zum Anschluss eines Kabels der Signal- und Datentechnik, insbesondere zum Anschluss eines Kabels, bei dem die verdrillten Adernpaare, mit einem metallischen Schirm umgeben sind (FTP = Foiled Twisted Pair bzw. PiMF = Paar in Metallfolie), so weist der elektrische Steckverbinder gemäß einer weiteren vorteilhaften Ausgestaltung zusätzlich eine zylinderförmige Hülse mit einem sich in Längsrichtung der Hülse erstreckenden, innerhalb der Hülse angeordneten kreuzförmigen Schirmungselement auf. Die vier Kontaktträgerteile sind dann derart innerhalb der zylinderförmigen Hülse angeordnet, dass die einzelnen Kontaktträgerteile durch die Arme des kreuzförmigen Schirmungselements voneinander getrennt sind. Hierdurch kann ein Übersprechen von einem Adernpaar auf ein anderes Adernpaar weitestgehend unterbunden werden, wozu die Hülse und das Schirmungselement vorzugsweise aus Metall bestehen. Zur vereinfachten Montage des elektrischen Steckverbinders sind dabei die Hülse und das Schirmungselement vorzugsweise einstückig ausgebildet.Serves the electrical connector for connecting a cable signal and data technology, in particular for connecting a cable in which the twisted wire pairs, with a metallic shield are surrounded (FTP = Foiled Twisted Pair or PiMF = pair in metal foil), so has the electrical connector according to a further advantageous embodiment, in addition a cylindrical sleeve with a longitudinally extending sleeve, arranged within the sleeve cross-shaped shielding element. The four contact carrier parts are then arranged inside the cylindrical sleeve such that the individual contact carrier parts are separated from one another by the arms of the cross-shaped shielding element. As a result, a crosstalk from one pair of wires to another pair of wires can be largely prevented, for which purpose the sleeve and the shielding element are preferably made of metal. For simplified installation of the electrical connector while the sleeve and the shielding element are preferably formed integrally.
Gemäß einer bevorzugten Ausgestaltung ragt das kreuzförmige Schirmungselement auf der dem Kabel zugewandten Seite aus der Hülse heraus, so dass an dem herausragenden Ende des Schirmungselements die metallischen Schirme der einzelnen verdrillten Adernpaare (PiMF) befestigt werden können, wodurch die Abschirmung zwischen den einzelnen Adernpaaren weiter verbessert und somit die Wahrscheinlichkeit eines Übersprechens von einem Adernpaar auf ein anderes Adernpaars weiter verringert wird.According to a preferred embodiment, the cross-shaped shielding element protrudes on the side facing the cable out of the sleeve, so that the metallic shields of the individual twisted pairs of wires (PiMF) can be attached to the protruding end of the Schirmungselements, whereby the shield between the individual pairs of wires further improved and thus further reducing the likelihood of crosstalk from one wire pair to another wire pair.
Um die Positionierung der einzelnen Kontaktträgerteile innerhalb der Hülse weiter zu erleichtern, ist am Innenumfang der Hülse vorzugsweise ein Anschlag für die Kontaktträgerteile ausgebildet. Nach dem Einstecken der Kontaktelemente in die einzelnen Kontaktträgerteile können diese somit einfach in die durch die Hülse und das kreuzförmige Schirmungselement gebildeten Kammern eingesteckt werden.In order to further facilitate the positioning of the individual contact carrier parts within the sleeve, a stop for the contact carrier parts is preferably formed on the inner circumference of the sleeve. After inserting the contact elements in the individual contact carrier parts, these can thus be easily inserted into the chambers formed by the sleeve and the cross-shaped shielding element.
Bei einer electrischen Steckverbindung bestehend aus einem Steckverbinder nach Anspruch 1 und einem Gegensteckverbinder, wobei der Steckverbinder einen ein Kabel umschließenden Griffkörper, einen eine Mehrzahl von Kontaktelementen aufnehmenden bzw. haltenden Kontaktträger und eine drehbar angeordnete Überwurfschraube mit einem Außengewinde und der Gegensteckverbinder eine Außenhülse mit einem zum Außengewinde der Überwurfschraube korrespondierenden Innengewinde und einen eine Mehrzahl von Gegenkontaktelementen aufnehmenden bzw. haltenden Gegenkontaktträger aufweist, wird die Eignung der Steckverbindung für die Signal- und Datenübertragung, insbesondere für Ethernet-Anwendungen dadurch auf einfache Art und Weise verbessert, dass die Gegenkontaktelemente des Gegensteckverbinders einen sich in axialer Richtung erstreckenden Bereich aufweisen, in dem der Außendurchmesser zur Impedanzanpassung verringert ist.In an electrical connector consisting of a connector according to
Um eine fehlerfreie Datenübertragung bei Steckverbindungen, insbesondere bei solchen, die bei Busverbindungen oder Netzwerken mit hohen Datenübertragungsraten eingesetzt werden, gewährleisten zu können, müssen bestimmte hochfrequente Randbedingungen berücksichtigt werden. Neben dem möglichst geringen Übersprechen zwischen einzelnen Adernpaaren ist dabei die Reduzierung der Rückflussdämpfung von besonderer Bedeutung. Die Rückflussdämpfung (Return Loss) wird im Wesentlichen durch die Homogenität des Wellenwiderstands bestimmt. Tritt in Ausbreitungsrichturig der elektromagnetischen Welle ein Impedanzsprung auf, so führt dies zu Reflektionen, die sich mit den zu übertragenden Nutzsignalen überlagern können, so dass es durch Interferenzen zur teilweisen Auslöschung des zu übertragenden Nutzsignals kommen kann.In order to ensure error-free data transmission in plug-in connections, in particular in those used in bus connections or networks with high data transmission rates, certain high-frequency boundary conditions must be taken into account. In addition to the lowest possible crosstalk between individual pairs of wires while reducing the return loss is of particular importance. The return loss (return loss) is essentially determined by the homogeneity of the characteristic impedance. Occurs in propagation direction of the electromagnetic wave an impedance jump, this leads to reflections that can be superimposed with the useful signals to be transmitted, so that it may be due to interference to the partial extinction of the useful signal to be transmitted.
Da bei einer elektrischen Steckverbindung, die im industriellen Bereich eingesetzt werden soll, neben den hochfrequenten Randbedingungen auch andere Anforderungen, wie eine möglichst hohe Schutzklasse, eine ausreichende Kompaktheit bei gleichzeitig hoher mechanischer Stabilität und eine möglichst einfache Herstellbarkeit berücksichtigt werden müssen, kann es vorkommen, dass die Kontaktelemente des Steckverbinders in der Praxis eine andere differenzielle Längsimpedanz aufweisen als die Gegenkontaktelemente des Gegensteckverbinders.Since in an electrical connector to be used in the industrial sector, in addition to the high-frequency boundary conditions other requirements, such as the highest possible protection class, sufficient compactness and high mechanical stability and ease of manufacture must be considered, it may happen that the contact elements of the connector in practice have a different differential longitudinal impedance than the mating contact elements of the mating connector.
Ein Unterschied zwischen der differenziellen Längsimpe-danz der Kontaktelemente des Steckverbinders und der differenziellen Längsimpedanz der Gegenkontaktelemente des Gegensteckverbinders kann dadurch weitestgehend reduziert werden, dass die Gegenkontaktelemente einen sich in axialer Richtung erstreckenden Bereich aufweisen, in dem der Außendurchmesser - im Vergleich zum Außendurchmesser in den anderen Bereichen des Gegenkontaktelements - verringert ist.A difference between the differential longitudinal impedance The contact elements of the connector and the differential longitudinal impedance of the mating contact elements of the mating connector can be largely reduced, that the mating contact elements have a region extending in the axial direction, in which the outer diameter - compared to the outer diameter in the other areas of the mating contact element - is reduced.
Dadurch ist eine Impedanzanpassung der Gegenkontaktelemente an die Kontaktelemente möglich, ohne dass andere Parameter der Steckverbindung, beispielsweise die elektrische Leitfähigkeit der Kontaktelemente und der Gegenkontaktelemente oder der Anstand der Kontaktelemente bzw. der Gegenkontaktelemente zueinander verändert werden müssen. Da die differenzielle Längsimpedanz vom Verhältnis des Durchmessers eines Kontaktelements bzw. Gegenkontaktelements zum Mittenabstand zu benachbarten Kontaktelemente bzw. Gegenkontaktelemente abhängt, kann die differenzielle Längsimpedanz der Gegenkontaktelemente durch Veränderung des Durchmessers der Gegenkontaktelemente so angepasst werden, dass die differenzielle Längsimpedanz der Gegenkontaktelemente näherungsweise einem vorgegebenen Sollwert, beispielsweise 100 Ohm entspricht.Thereby, an impedance matching of the mating contact elements to the contact elements is possible without other parameters of the connector, for example, the electrical conductivity of the contact elements and the mating contact elements or the decency of the contact elements and the mating contact elements to each other must be changed. Since the differential longitudinal impedance depends on the ratio of the diameter of a contact element or mating contact element to the center distance to adjacent contact elements or mating contact elements, the differential longitudinal impedance of the mating contact elements by changing the diameter of the mating contact elements can be adjusted so that the differential longitudinal impedance of the mating contact elements approximately a predetermined setpoint, for example, corresponds to 100 ohms.
Gemäß einer Ausgestaltung der elektrischen Steckverbindung ist das den Gegenkontaktelementen zugewandte Ende der Kontaktelemente stiftförmig und das den Kontaktelementen zugewandte Ende der Gegenkontaktelemente hohl ausgebildet, so dass die stiftförmigen Enden der Kontaktelemente in die hohlen Enden der Gegenkontaktelemente eingesteckt werden können. Sind die den Kontaktelementen abgewandten Enden der Gegenkontaktelemente stiftförmig ausgebildet, so können die Gegenkontaktelemente geräteseitig einfach mit einer Leiterplatte, beispielsweise im Wellenlötverfahren verbunden werden.According to one embodiment of the electrical plug connection, the counter contact elements facing the end of the contact elements pin-shaped and the contact elements facing the end of the mating contact elements is hollow, so that the pin-shaped ends of the contact elements can be inserted into the hollow ends of the mating contact elements. If the ends of the mating contact elements facing away from the contact elements are pin-shaped, the mating contact elements can simply be connected to a circuit board on the device side, for example by wave soldering.
Um bei der elektrischen Steckverbindung auch im Gegenstecker ein Übersprechen zwischen einzelnen Adern oder einzelnen Adernpaaren zu unterbinden, besteht der Gegenkontaktträger des Gegensteckverbinders gemäß einer Ausgestaltung aus vier Gegenkontaktträgerteilen, die jeweils eine viertelkreisförmige Grundfläche aufweisen, wobei in jedem Gegenkontaktträgerteil mindestens eine sich in Längsrichtung erstreckende Bohrung zur Aufnahme eines Gegenkontaktelements angeordnet ist. Bei einer derartigen Ausgestaltung des Gegenkontaktträgers sind die vier Gegenkontaktträgerteile durch ein innerhalb der Außenhülse angeordnetes, sich in Längsrichtung der Außenhülse bzw. des Gegenkontaktträgers erstreckendes kreuzförmiges Schirmungselement gegeneinander abgeschirmt. Die vier Kontaktträgerteile sind dabei an ihrem Außenumfang bereichsweise miteinander verbunden, so dass das kreuzförmige Schirmungselement im montierten Zustand des Gegensteckverbinders in entsprechenden Nuten, die zwischen den einzelnen Gegenkontaktträgerteilen ausgebildet sind, angeordnet ist.In order to prevent crosstalk between individual wires or individual wire pairs in the mating connector in the mating connector, the mating contact carrier of the mating connector according to an embodiment of four mating contact carrier parts, each having a quarter-circle base, wherein in each mating contact carrier part at least one longitudinally extending bore for Recording a mating contact element is arranged. In such an embodiment of the mating contact carrier, the four mating contact carrier parts are arranged by an inside of the outer sleeve, Shielded in the longitudinal direction of the outer sleeve and the mating contact carrier extending cross-shaped shielding element against each other. The four contact carrier parts are partially connected to each other at their outer periphery, so that the cross-shaped shielding element in the assembled state of the mating connector in corresponding grooves formed between the individual mating contact carrier parts, is arranged.
Gemäß einer weiteren Ausgestaltung der elektrischen Steckverbindung, bei der sowohl der Gegensteckverbinder als auch der Steckverbinder ein kreuzförmiges Schirmungselement aufweist, haben die einzelnen Arme des kreuzförmigen Schirmungselements des Steckverbinders auf der dem Gegensteckverbinder zugewandten Seite jeweils eine sich in Längsrichtung des Steckverbinders erstreckende Verlängerung und die einzelnen Arme des kreuzförmigen Schirmungselements des Gegensteckverbinders auf der dem Steckverbinder zugewandten Seite jeweils eine sich in Längsrichtung des Gegensteckverbinders erstreckende korrespondierende Gegenverlängerung. Die Verlängerungen und die Gegenverlängerungen sind so angeordnet und ausgebildet, dass sie sich in axialer Richtung überlappen, wenn der Steckverbinder und der Gegensteckverbinder miteinander verbunden sind. Durch das axiale "Überlappen" des kreuzförmigen Schirmungselements des Steckverbinders mit dem kreuzförmigen Schirmungselement des Gegensteckverbinders wird ein Übersprechen von einem Adernpaar auf ein anderes Adernpaar über die gesamte Länge der elektrischen Steckverbindung effektiv unterdrückt.According to a further embodiment of the electrical connector, in which both the mating connector and the connector has a cross-shaped shielding element, the individual arms of the cross-shaped Schirmungselements of the connector on the mating connector side facing each extending in the longitudinal direction of the connector extension and the individual arms the cross-shaped shielding element of the mating connector on the side facing the connector in each case one extending in the longitudinal direction of the mating connector corresponding counter-extension. The extensions and the counter-extensions are arranged and formed so that they overlap in the axial direction when the connector and the mating connector are connected together. By the axial "overlapping" of the cross-shaped shielding element of the connector with the cross-shaped shielding element of the mating connector crosstalk from one pair of wires to another pair of wires over the entire length of the electrical connector is effectively suppressed.
Neben dem eingangs beschriebenen elektrischen Steckverbinder betrifft die vorliegende Erfindung gemäß Anspruch 8 auch ein Verfahren zum Anschließen der Adern eines mehradrigen Kabels an einen elektrischen Steckverbinder, wobei der elektrische Steckver-binder - wie zuvor beschrieben - einen Griffkörper, einen Kontaktträger zur Aufnahme einer Mehrzahl von Kontaktelementen und ein drehbar angeordnetes hülsenartiges Gewindeteil aufweist. Der Kontaktträger des Steckverbinders weist dabei eine der Anzahl der Kontaktelemente entsprechende Anzahl an nach außen offenen, parallel zur Längsachse des Kontaktträgers verlaufenden Nuten und in der den Adern abgewandten Stirnseite des Kontaktträgers, angrenzend an die Nuten, eine entsprechende Anzahl an Durchgangslöchern auf. Bei dem Verfahren ist das Anschließen der einzelnen abisolierten Adern durch folgende Schritte gekennzeichnet:
- Verbinden der einzelnen abisolierten Enden der Adern mit den zugewandten Enden der einzelnen Kontaktelemente,
- Durchstecken der den Adern abgewandten Enden der Kontaktelemente durch die Durchgangslöcher in der Stirnseite des Kontaktträgers, wobei die Kontaktelemente beim Durchstecken einen Winkel zur Längsachse des Kontaktträgers größer Null aufweisen, und
- Einschwenken der Kontaktelemente in die Nuten im Kontaktträger, so dass die Kontaktelemente und mit ihnen die Adern parallel zur Längsachse des Kontaktträgers verlaufen.
- Connecting the individual stripped ends of the wires to the facing ends of the individual contact elements,
- Passing through the through holes in the end face of the contact carrier, the contact elements facing away from the wires of the contact elements, wherein the contact elements have an angle to the longitudinal axis of the contact carrier greater than zero when passing through, and
- Swiveling the contact elements in the grooves in the contact carrier, so that the contact elements and with them the wires are parallel to the longitudinal axis of the contact carrier.
Vorteilhafterweise ist das erfindungsgemäße Verfahren bei einem elektrischen Steckverbinder, bei dem das den Adern zugewandte Ende der Kontaktelemente hohl ausgebildet ist, dadurch maschinell besonders einfach durchführbar, dass die einzelnen abisolierten Enden der Adern in die hohlen Enden der Kontaktelemente eingesteckt und durch mechanisches Zusammendrücken (Crimpen) der Enden der einzelnen Adern mit den einzelnen Kontaktelementen elektrisch leitend verbunden werden. Dazu kann ein Kontaktelement mit in das hohle Ende eingeführter Ader in die Aufnahme einer entsprechenden Pressbacke eingelegt werden und anschließend durch Niederdrücken einer Gegenbacke das Kontaktelement im Bereich der eingeführten Ader zusammengedrückt werden, wodurch das abisolierte Ende der Ader mit dem Kontaktelement elektrisch und mechanisch fest verbunden wird.Advantageously, the inventive method is in an electrical connector in which the wires facing the end of the contact elements is hollow, characterized by machine particularly easy to carry out that the individual stripped ends of the wires inserted into the hollow ends of the contact elements and by mechanical compression (crimping) the ends of the individual wires are electrically connected to the individual contact elements. For this purpose, a contact element inserted into the hollow end of the core can be inserted into the receptacle of a corresponding pressing jaw and then pressed together by depressing a counter-jaw, the contact element in the region of the inserted wire, whereby the stripped end of the wire is electrically and mechanically firmly connected to the contact element ,
Sind die einzelnen Kontaktelemente mit dem damit elektrisch leitend verbundenen Adern in den Kontaktträger oder in einzelne Kontaktträgerteile eingesetzt, so wird der Kontaktträger bzw. die Kontaktträgerteile vorzugsweise in eine zylinderförmige Hülse mit einem innerhalb der Hülse angeordneten, sich in Längsrichtung der Hülse erstreckenden kreuzförmigen Schirmungselement eingeschoben. Danach wird das hülsenartige Gewindeteil auf die Hülse aufgeschoben und anschließend die mit den Kontaktelementen verbundenen Adern und das Kontaktträgerteil bzw. die Kontaktträgerteile zur Herstellung eines Griffkörpers umspritzt.If the individual contact elements with the wires thus connected electrically conductively inserted into the contact carrier or in individual contact carrier parts, the contact carrier or the contact carrier parts is preferably inserted into a cylindrical sleeve with a disposed within the sleeve, extending in the longitudinal direction of the sleeve cross-shaped shielding element. Thereafter, the sleeve-like threaded portion is pushed onto the sleeve and then encapsulated with the contact elements connected to the wires and the contact carrier part or the contact carrier parts for producing a handle body.
