Description

Die Erfindung betrifft einen Steckverbinder für geschirmte Daten- und/oder Telekommunikations-Kabel gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a connector for shielded data and / or telecommunication cables according to the preamble of claim 1.

Für Daten- und/oder Telekommunikations-Netze werden in der Regel geschirmte Kabel verwendet, um das Abstrahlen von Hochfrequenz-Signalen und das Auffangen von Hochfrequenz-Störungen zu verhindern. Bei Steckverbindungen solcher Kabel muss dementsprechend dafür gesorgt werden, dass eine Abschirmung auch im Bereich des Steckverbinders gewährleistet ist. Es werden daher für die Steckverbinder abgeschirmte Gehäuse verwendet, die sowohl die Steckverbindungskontakte als auch den Anschluss der Adern des Kabels abschirmen. Die Schirmung des Kabels muss über das Gehäuse und die Steckverbindung an die Schirmung eines anzuschließenden Kabels weitergegeben werden. Hierzu ist bei bekannten Steckverbindern ein Schirmkontakt vorgesehen, der mit der Schirmung des Kabels in leitende Berührung kommt und mit wenigstens einem Kontaktbügel der Steckverbindung in leitender Verbindung steht.For data and / or telecommunications networks shielded cables are usually used to prevent the radiating of high-frequency signals and the capture of high-frequency interference. In the case of plug-in connections of such cables, care must therefore be taken to ensure that shielding is also ensured in the area of the plug connector. Shielded housings are therefore used for the plug connectors which shield both the plug connection contacts and the connection of the wires of the cable. The shield of the cable must be passed through the housing and the connector to the shield of a cable to be connected. For this purpose, a shield contact is provided in known connectors, which comes into conductive contact with the shield of the cable and is in conductive connection with at least one contact bracket of the connector.

Als Stand der Technik werden die US 5,820,412 sowie die EP 0 600 120 A1 genannt.As state of the art, the US 5,820,412 as well as the EP 0 600 120 A1 called.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der Eingangs genannten Gattung so zu verbessern, dass dieser einerseits in Herstellung und Montage einfach ist und andererseits eine zuverlässige Weitergabe der Schirmung gewährleistet.The invention has the object to improve a connector of the type mentioned input so that this one hand in production and installation is easy and on the other hand ensures a reliable transfer of the shielding.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Steckverbinder mit den Merkmalen des Anspruchs 1.This object is achieved by a connector with the features of claim 1.

Vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Erfindungsgemäß wird für die Weitergabe der Schirmung von dem Kabel zu dem Kontakt der Steckverbindung ein einstückiges Schirmblech verwendet, welches als Stanz-Biege-Teil hergestellt wird. Dadurch ist zum einen eine kostengünstige Herstellung und eine einfache Montage möglich und zum anderen ist eine zuverlässige leitende Verbindung zwischen der Schirmung des Kabels und dem Schirmkontakt der Steckverbindung ohne Übergangswiderstände gewährleistet. Vorzugsweise ist das Schirmblech aus einem Federmetall hergestellt. Der Schirmkontakt ist als wenigstens eine federnde Schirmabnahmelasche ausgebildet, die beim Zusammenfügen des Steckverbindergehäuses unter ihrer Federelastizität zur Anlage an der Schirmung des angeschlossenen Kabels kommt. Dadurch ist ein gut leitender Kontakt zwischen dem Schirmblech und der Schirmung des Kabels ohne zusätzlicher Montagemaßnahme sichergestellt.According to the invention for the transmission of the shield of the cable to the contact of the connector is a one-piece Shield used, which is manufactured as a punch-bending part. As a result, on the one hand a cost-effective production and easy installation possible and on the other hand, a reliable conductive connection between the shield of the cable and the shield contact of the connector is ensured without contact resistance. Preferably, the shroud is made of a spring metal. The shield contact is designed as at least one resilient Schirmabnahmelasche that comes when mating the connector housing under its spring elasticity to rest against the shield of the connected cable. This ensures a good conductive contact between the shroud and the shield of the cable without additional installation action.

In einer vorteilhaften Ausführung der Erfindung ist an dem Schirmblech weiter einstückig eine Kontaktfederlasche angeformt, die aus dem Gehäuse des Steckverbinders nach außen geführt ist. In dieser Ausführung eignet sich der Steckverbinder insbesondere zum Einbau in eine Montageplatte, z. B. in die Montageplatte eines Patch-Panels oder eines Gerätes. Beim Einbau des Steckverbinders in eine solche Montageplatte kommt die außen an dem Gehäuse angeordnete Kontaktfederlasche in federnden Kontakt mit der Montageplatte, so dass ein zuverlässiger Massekontakt der Schirmung mit der Montageplatte gewährleistet ist. Um die Montage des Steckverbinders zu vereinfachen, wird in einer weiteren Ausführung das Schirmblech durch Ausbildung geeigneter Haltelaschen gleichzeitig dazu verwendet, den Kontaktträger in dem Steckverbinder-Gehäuse zu halten und zu positionieren.In an advantageous embodiment of the invention, a contact spring tab is integrally formed on the shield plate further in one piece, which is guided out of the housing of the connector to the outside. In this embodiment, the connector is particularly suitable for installation in a mounting plate, for. B. in the mounting plate of a patch panel or a device. When installing the connector in such a mounting plate, the outside of the housing arranged contact spring tab comes into resilient contact with the mounting plate, so that a reliable ground contact of the shield is ensured with the mounting plate. To simplify the assembly of the connector, in a further embodiment, the shield plate is simultaneously used by training suitable retaining tabs to hold the contact carrier in the connector housing and position.

Die Höhe der Abschnitte 30 und 32 beträgt jeweils etwa die halbe Höhe des gesamten Ladestückes 26.The charging piece 26 has the same rectangular profile in cross section as the inner profile cross section of the upper housing shell 20, as in FIG. 3 can be seen. In longitudinal section, the charging piece 26 is stepped. An upper portion 30 of the loading piece 26 abutting the cover plate 22 extends substantially the entire length of the U-shaped inner profile of the upper housing shell 20. A lower portion 32 is shorter in the axial direction, the end face of this lower portion 32 being stepped the end surface of the upper portion 30 is reset. The rear rear surface of the charging piece 26 is continuous over its entire height. The height of sections 30 and 32 is in each case about half the height of the entire loading piece 26.

Das Ladestück 26 dient zur Aufnahme der Adern 12 des Kabels 10. Hierzu weist das Ladestück 26 in seinem oberen Abschnitt 30 vier in einer Ebene beabstandete nebeneinander angeordnete axial durchgehende Bohrungen 34 auf, in welchen vier der acht Adern 12 des Kabels 10 von der Rückseite des Ladestückes 26 eingeführt werden, wie dies am besten in Figur 2 zu sehen ist. Der untere Abschnitt 32 weist vier in Axialrichtung durchgehende Rinnen 36 auf, die gegen die untere Fläche des unteren Abschnittes 32 hin offen sind. Die Rinnen 36 weisen denselben gegenseitigen Abstand auf wie die Bohrungen 34 und sind in einer entsprechenden Position angeordnet. Die Rinnen 36 dienen zum Einlegen der anderen vier Adern 12, wie dies in den Figuren 1 bis 3 ersichtlich ist. Das Ladestück 26 weist in seinem oberen Abschnitt 30 Eintrittsschlitze 38 auf, die von der freiliegenden unteren Fläche des oberen Abschnittes 30 vor dem unteren Abschnitt 32 ausgehen und in den oberen Abschnitt 30 hineinführen und jeweils die Bohrungen 34 durchqueren. Entsprechend weist der untere Abschnitt 32 Eintrittsschlitze 40 auf, die von dessen unterer Seite ausgehen und jeweils die Rinnen 36 queren. Die Eintrittsschlitze 38 und 40 dienen in später beschriebener Weise zum Einführen von Schneidklemmkontakten.The charging piece 26 serves to receive the cores 12 of the cable 10. For this purpose, the charging piece 26 has in its upper portion 30 four axially spaced bores 34 spaced apart in one plane, in which four of the eight cores 12 of the cable 10 from the rear side of the cable 10 Loading pieces 26 are introduced as best in FIG. 2 you can see. The lower portion 32 has four axially continuous grooves 36 which are open towards the lower surface of the lower portion 32. The grooves 36 have the same mutual distance on how the holes 34 and are arranged in a corresponding position. The grooves 36 serve to insert the other four wires 12, as shown in the FIGS. 1 to 3 is apparent. The loading piece 26 has in its upper portion 30 inlet slots 38 which extend from the exposed lower surface of the upper portion 30 in front of the lower portion 32 and lead into the upper portion 30 and each pass through the holes 34. Correspondingly, the lower section 32 has entry slots 40, which emanate from its lower side and respectively cross the channels 36. The entry slots 38 and 40 serve in the manner described later for the introduction of insulation displacement contacts.

Hinter dem U-förmigen Innenprofil der oberen Gehäuseschale 20, welches zur Aufnahme des Ladestückes 26 dient, ist die obere Deckplatte 22 dieser Gehäuseschale 20 verstärkt und mit einer in Längsrichtung verlaufenden mittigen Mulde 42 ausgebildet, in welche das Kabel 10 eingelegt wird. An dem rückwärtigen Ende ist oberhalb der Mulde 42 in axialer Verlängerung der Gehäuseschale 20 ein T-förmiger Ansatz 44 angeformt.Behind the U-shaped inner profile of the upper housing shell 20, which serves to receive the charging piece 26, the upper cover plate 22 of this housing shell 20 is reinforced and formed with a longitudinally extending central recess 42, in which the cable 10 is inserted. At the rear end, a T-shaped projection 44 is integrally formed above the trough 42 in the axial extension of the housing shell 20.

Die Montage des Oberteil 16 des Steckverbinders geschieht in folgender Weise:The assembly of the upper part 16 of the connector is done in the following manner:

Zunächst werden die Adern 12 des Kabels 10 freigelegt. Weiter wird im Anschluß an die freigelegten Adern 12 die äußere Isolation des Kabels 10 entfernt, so dass über eine gewisse Länge das Schirmgeflecht 14 freigelegt ist. Nun werden vier der Adern 12 in die Bohrungen 34 des Ladestücks 26 eingeführt und anschließend die restlichen vier Adern 12 in die Rinnen 36 eingelegt, wobei innen vorspringende Rippen 37 dieser Rinnen 36 die Adern 12 geklemmt halten. Anschließend wird das auf diese Weise mit dem Kabel 10 verbundene Ladestück 26 von der vorderen Stirnseite her mittels der Führungsstege 28 in die obere Gehäuseschale 20 eingeschoben und mittels der Rastfedern 29 verrastet. Das Kabel 10 mit seinem freigelegten Schirmgeflecht 14 kommt dabei in der Mulde 42 zu liegen. Anschließend wird ein Kabelbinder 46 um das Kabel 10 und den T-förmigen Ansatz 44 gelegt und festgezogen, so dass das Kabel 10 mit dem Ladestück 26 in der oberen Gehäuseschale 20 fest montiert und zugentlastet ist. Das Schirmgeflecht 14 liegt dabei im Bereich der Mulde 42 in leitender Berührung mit der metallischen oberen Gehäuseschale 20. Anschließend werden die vorderen aus den Bohrungen 34 bzw. den Rinnen 36 herausstehenden Enden der Adern 12 abgeschnitten, so dass das Oberteil 16 des Steckverbinders vollständig montiert ist, wie dies die Figuren 1 bis 3 zeigen.First, the wires 12 of the cable 10 are exposed. Further, following the exposed wires 12, the outer insulation of the cable 10 is removed, so that over a certain length the braided shield 14 is exposed. Now four of the wires 12 are inserted into the holes 34 of the charging piece 26 and then inserted the remaining four wires 12 in the grooves 36, wherein inside projecting ribs 37 of these grooves 36 hold the wires 12 clamped. Subsequently, the charging piece 26 connected in this way to the cable 10 is inserted from the front end side by means of the guide webs 28 into the upper housing shell 20 and locked by means of the locking springs 29. The cable 10 with its exposed braided shield 14 comes to lie in the trough 42. Subsequently, a cable tie 46 around the cable 10 and the T-shaped approach 44 and tightened so that the cable 10 with the charging piece 26 in the upper housing shell 20 is fixed and strain relieved. The braided shield 14 is in the region of the trough 42 in conductive contact with the metallic upper housing shell 20. Subsequently, the front of the holes 34 and the grooves 36 protruding ends of the wires 12 are cut off, so that the upper part 16 of the connector is completely assembled like this FIGS. 1 to 3 demonstrate.

Aufbau und Montage des Unterteils 18 wird nachfolgend anhand der Figuren 4 bis 7 erläutert.Construction and assembly of the lower part 18 will be described below with reference to FIGS. 4 to 7 explained.

Das Unterteil 18 weist eine untere Gehäuseschale 48 auf, die in gleicher Weise wie die obere Gehäuseschale 20 vorzugsweise metallisch leitend ist und vorzugsweise als Metall-Druckgußteil, insbesondere als Zink-Druckgußteil, gefertigt wird. Die untere Gehäuseschale 48 ist kastenförmig in der Weise ausgebildet, daß sie durch die obere Gehäuseschale 20 zu einem geschlossenen abschirmenden Gehäuse ergänzt wird. Die Form der unteren Gehäuseschale 48 ist am deutlichsten in Figur 4 zu erkennen. Die untere Gehäuseschale 48 weist eine untere Bodenplatte 50 auf, an welcher rechtwinklig nach oben führende Seitenwangen 52 angeformt sind. In den Seitenwangen 52 sind Ausschnitte 54 vorgesehen, die in der Form den Seitenwangen 24 der oberen Gehäuseschale 20 entsprechen. Im vorderen Bereich ist die untere Gehäuseschale 48 auch an der Oberseite geschlossen. In der vorderen Stirnfläche der unteren Gehäuseschale 48 ist eine Einstecköffnung 56 ausgespart, die zum Einstecken eines Western-Steckers dient.The lower part 18 has a lower housing shell 48 which is preferably metallically conductive in the same way as the upper housing shell 20 and is preferably made as a metal die cast part, in particular as a zinc die cast part. The lower housing shell 48 is box-shaped in such a way that it is supplemented by the upper housing shell 20 to a closed shielding housing. The shape of the lower shell 48 is most apparent in FIG FIG. 4 to recognize. The lower housing shell 48 has a lower base plate 50, on which side walls 52 leading at right angles are formed. In the side cheeks 52 cutouts 54 are provided which correspond in shape to the side cheeks 24 of the upper housing shell 20. In the front area, the lower housing shell 48 is closed at the top. In the front end face of the lower housing shell 48, an insertion opening 56 is recessed, which serves for the insertion of a Western plug.

In die untere Gehäuseschale 48 wird von der Hinterseite axial ein Kontaktträger 58 aus Kunststoff eingeschoben. Die Breite des Kontaktträgers 58 entspricht der Breite des Innenquerschnitts der Gehäuseschale 48. In seinem vorderen Bereich weist der Kontaktträger 58 acht nebeneinander angeordnete Verbinderkontakte 60 auf. Ist der Kontaktträger 58 vollständig in die untere Gehäuseschale 48 eingeschoben, wie dies in Figur 6 gezeigt ist, so liegen die Verbinderkontakte 60 in herkömmlicher Weise hinter der Einstecköffnung 56, um einen in diese Einstecköffnung 56 eingesteckten Western-Stecker zu kontaktieren. Im hinteren Bereich ist der Kontaktträger 58 in einer der stufenförmigen Ausbildung des Ladestückes 26 korrespondierenden Form stufenförmig ausgebildet. In diesem Bereich trägt der Kontaktträger 58 an seiner Oberseite zwei Reihen von nebeneinander angeordneten Schneidklemmkontakten 62. Jeder dieser Schneidklemmkontakte 62 ist leitend mit einem der Verbinderkontakte 60 verbunden. Die Schneidklemmkontakte 62 sind auf der abgestuften Oberseite des Kontaktträgers 58 so angeordnet, daß sie beim Aufsetzen des Ladestückes 26 auf den Kontaktträger 58 in die Eintrittsschlitze 38 bzw. 40 des Ladestückes 26 eindringen.In the lower housing shell 48, a contact carrier 58 made of plastic is inserted axially from the rear side. The width of the contact carrier 58 corresponds to the width of the inner cross section of the housing shell 48. In its front region, the contact carrier 58 has eight connector contacts 60 arranged next to one another. Is the contact carrier 58 completely inserted into the lower housing shell 48, as in FIG. 6 is shown, the connector contacts 60 are in conventional Way behind the insertion opening 56 to contact a plugged into this insertion port 56 Western plug. In the rear region of the contact carrier 58 is step-shaped in a step-shaped configuration of the charging piece 26 corresponding shape. In this area, the contact carrier 58 carries at its top two rows of juxtaposed insulation displacement contacts 62. Each of these insulation displacement contacts 62 is conductively connected to one of the connector contacts 60. The insulation displacement contacts 62 are arranged on the stepped upper side of the contact carrier 58 so that they penetrate when placing the charging piece 26 on the contact carrier 58 in the inlet slots 38 and 40 of the charging piece 26.

Der Kontaktkörper 58 aus isolierendem Kunststoff ist in ein Schirmblech 64 eingesetzt und wird zusammen mit diesem Schirmblech 64 in die untere Gehäuseschale 48 eingeschoben. Die Form und die Herstellung des Schirmbleches 64 ist in den Figuren 9 und 10 gezeigt.The contact body 58 made of insulating plastic is inserted into a shield plate 64 and is inserted together with this shield plate 64 in the lower housing shell 48. The shape and the manufacture of the shielding plate 64 is in the Figures 9 and 10 shown.

Das Schirmblech 64 ist ein einstückiges Stanz-Biege-Teil aus einem leitenden Federmetall. Zunächst wird das Schirmblech 64 in der in Figur 9 gezeigten Form ausgestanzt. Aus diesem Stanzteil wird das Schirmblech 64 an den in Figur 9 eingezeichneten Biegelinien in die in Figur 10 gezeigte Form gebogen.The shield plate 64 is a one-piece stamped and bent part made of a conductive spring metal. First, the shield plate 64 in the in FIG. 9 punched out form shown. From this stamped part, the shield plate 64 is connected to the in FIG. 9 drawn bending lines in the in FIG. 10 bent shape shown.

Das Schirmblech 64 weist eine Grundplatte 66 auf, auf die der Kontaktträger 58 aufgesetzt wird. Aus der Grundplatte 66 ist in deren mittleren hinterem Bereich eine hintere Haltelasche 68 ausgestanzt und hochgebogen. Im mittleren Bereich der Längserstreckung des in Figur 9 gezeigten Stanzteils ragen beiderseits rechtwinklig Seitenarme 70 ab, die von der Grundplatte 66 rechtwinklig nach oben hochgebogen werden. Von diesen Seitenarmen 70 ragt jeweils eine vordere Haltelasche 72 ab, die von dem Seitenarm 70 nach hinten absteht und in dem in Figur 10 gezeigten gebogenen Zustand an ihrem Ende nach innen abgewinkelt ist. Der Kontaktträger 58 wird auf die Grundplatte 66 aufgesetzt, wobei die hintere Haltelasche 68 mit ihrem oberen parallel zur Grundplatte 66 abgewinkelten Ende den Kontaktträger 58 nach hinten abstützt und auf der Grundplatte 66 hält. Seitlich wird der Kontaktträger 58 zwischen den Seitenarmen 70 geführt und durch die nach innen abgewinkelten vorderen Haltelaschen 72 gegen eine Verschiebung nach vorn fixiert, wie dies aus Figur 4 ersichtlich ist.The shield plate 64 has a base plate 66, on which the contact carrier 58 is placed. From the base plate 66, a rear retaining tab 68 is punched out and bent up in its central rear region. In the middle region of the longitudinal extent of the in FIG. 9 shown punching part protrude on either side at right angles side arms 70, which are bent upwards from the base plate 66 at right angles. Of these side arms 70 each protrudes from a front retaining tab 72 which protrudes from the side arm 70 to the rear and in the in FIG. 10 shown curved state is angled inwardly at its end. The contact carrier 58 is placed on the base plate 66, wherein the rear retaining tab 68 with its upper parallel to the base plate 66 angled end the contact carrier 58 is supported to the rear and holds on the base plate 66. Laterally, the contact carrier 58 is guided between the side arms 70 and fixed by the inwardly angled front retaining tabs 72 against displacement forward, as can be seen from FIG. 4 is apparent.

An den Enden der Seitenarme 70 sind rechtwinklig nach vorne weisende Kontaktbügel 74 ausgebildet. Das nach vorne weisende Ende der Grundplatte 66 wird nach unten abgebogen und bildet eine an der Unterseite der Grundplatte 66 nach rückwärts gerichtete Kontaktfederlasche 76. Im hinteren Bereich des in Figur 9 gezeigten Stanzteils ragen von der Grundplatte 66 beiderseitig rechtwinklig Schirmabnahmearme 78 ab, die von der Grundplatte 66 rechtwinklig nach oben gebogen werden. Die oberen Enden der Schirmabnahmearme 78 werden nach innen gebogen und bilden muldenförmige, sich überlappende Schirmabnahmelaschen 80. Schließlich wird das hintere Ende der Grundplatte 66 rechtwinklig nach oben gebogen und bildet eine mit einem kreisbogenförmigen Ausschnitt versehene Schirmplatte 82.At the ends of the side arms 70 right-facing forward contact bracket 74 are formed. The forwardly facing end of the base plate 66 is bent downwards and forms on the underside of the base plate 66 to the rearwardly directed contact spring tab 76. In the rear of the punching shown in Figure 9 from the base plate 66 protrude from each other at right angles on both sides Schirmabnahmearme 78, from the Base plate 66 are bent at right angles upwards. The top ends of the screen removal arms 78 are bent inwardly to form trough-shaped, overlapping screen removal tabs 80. Finally, the rear end of the base panel 66 is bent upright at right angles to form a circular arcuate panel plate 82.

Die Montage des Unterteils 18 wird nachfolgend anhand der Figuren 4 bis 8 erläutert. Zunächst wird in der beschriebenen Weise der Kontaktträger 58 auf die Grundplatte 66 aufgesetzt und zwischen der hinteren Haltelasche 68, den Seitenarmen 70 und den vorderen Haltelaschen 72 positioniert und an dem Schirmblech 64 fixiert. Die Kontaktfederlasche 76 ist dabei noch nicht abgebogen. Diese Situation ist in Figur 4 dargestellt. Dann wird das Schirmblech 64 mit dem Kontaktträger 58 von hinten axial in die untere Gehäuseschale 48 eingeschoben, wie dies Figur 5 zeigt. Dabei tritt die noch nicht abgebogene Kontaktfederlasche 76 durch einen Schlitz 84 der unteren Gehäuseschale 48 aus, der in der vorderen Stirnseite der unteren Gehäuseschale 48 oberhalb der Bodenplatte 50 vorgesehen ist. Ist das Schirmblech 64 mit dem Kontaktträger 58 vollständig axial in die untere Gehäuseschale 48 geschoben, so ergibt sich die in Figur 6 gezeigte Situation. Die Verbinderkontakte 60 des Kontaktträgers 58 befinden sich in der Steckeraufnahme der unteren Gehäuseschale 48 hinter der Einstecköffnung 56. Die nach vorn gerichteten Kontaktbügel 74 befinden sich beiderseits in der Steckeraufnahme hinter der Einstecköffnung 56, um die seitlichen Schirmkontakte eines eingesteckten Steckers zu kontaktieren. Die Schneidklemmkontakte 62 befinden sich in dem oben offenen Bereich der unteren Gehäuseschale 48. Die nach innen gebogenen Schirmabnahmelaschen 80 befinden sich hinter den Ausschnitten 54 im hinteren Endbereich der unteren Gehäuseschale 48. Die Schirmplatte 82 schließt die untere Gehäuseschale 48 abschirmend unterhalb der Schirmabnahmelaschen 80 ab. In dieser Position wird der Kontaktträger 58 mit der unteren Gehäuseschale 48 verrastet, wozu beiderseits an dem Kontaktträger 58 angeformte Rastvorsprünge 86 in Rastaussparungen 88 der Seitenwangen 52 der unteren Gehäuseschale 48 einrasten.The assembly of the lower part 18 will be explained below with reference to FIGS 4 to 8. First, in the manner described, the contact carrier 58 is placed on the base plate 66 and positioned between the rear retaining tab 68, the side arms 70 and the front retaining tabs 72 and fixed to the shield plate 64. The contact spring tab 76 is not bent yet. This situation is in FIG. 4 shown. Then the shield plate 64 is pushed with the contact carrier 58 from the rear axially into the lower housing shell 48, like this FIG. 5 shows. In this case, the not yet bent contact spring tab 76 exits through a slot 84 of the lower housing shell 48, which is provided in the front end of the lower housing shell 48 above the bottom plate 50. If the shield plate 64 is pushed completely axially into the lower housing shell 48 with the contact carrier 58, then the in FIG. 6 shown situation. The connector contacts 60 of the contact carrier 58 are located in the connector receptacle of the lower housing shell 48 behind the insertion opening 56th Die Forward facing contact bars 74 are located on both sides in the plug receptacle behind the insertion opening 56 to contact the side shield contacts of an inserted plug. The insulation displacement contacts 62 are located in the open top region of the lower shell 48. The inwardly bent Schirmabnahmelaschen 80 are located behind the cutouts 54 in the rear end of the lower housing shell 48. The shield plate 82 closes the lower housing shell 48 shielding below the Schirmabnahiltaschen 80 from. In this position, the contact carrier 58 is latched to the lower housing shell 48, including on both sides of the contact carrier 58 integrally formed latching projections 86 snap into locking recesses 88 of the side walls 52 of the lower housing shell 48.

Nach dem Verrasten des Kontaktträgers 58 und damit des Schirmbleches 64 in der unteren Gehäuseschale 48 wird die Kontaktfederlasche 76 an der vorderen Stirnseite der Gehäuseschale 48 nach unten und nach hinten abgebogen, wie dies Figur 7 zeigt. Die Kontaktfederlasche 76 weist in der gebogenen Form die Gestalt eines Dreiecks auf, welches sich einerseits an dem Schlitz 84 und mit dem freien Ende der Kontaktfederlasche 76 an der Bodenplatte 50 abstützt. Der Scheitel der dreieckförmig gebogenen Kontaktfederlasche 76 ist auf diese Weise gegen die Bodenplatte 50 hin federnd ausgebildet.After locking the contact carrier 58 and thus the shield plate 64 in the lower housing shell 48, the contact spring tab 76 is bent at the front end side of the housing shell 48 down and to the rear, like this FIG. 7 shows. The contact spring tab 76 has the shape of a triangle in the curved shape, which is supported on the one hand on the slot 84 and the free end of the contact spring tab 76 on the bottom plate 50. The apex of the triangular-shaped contact spring tab 76 is resiliently formed in this way against the bottom plate 50.

In der in Figur 7 gezeigten Darstellung sind somit sowohl das Oberteil 16 als auch das Unterteil 18 vollständig montiert. Es wird nun das Oberteil 16 in das Unterteil 18 eingesetzt, wobei die Seitenwangen 24 der oberen Gehäuseschale 20 in die Ausschnitte 54 der Seitenwangen 52 der unteren Gehäuseschale 48 eingesetzt werden. Die Seitenwangen 24 und 52 sind dabei an ihrer Umfangslinie abgestuft, so dass zwischen den Seitenwangen 24 und 52 keine von innen nach außen durchgehende Stoßfuge entsteht. In dem zusammengefügten Zustand werden die obere Gehäuseschale 20 und die untere Gehäuseschale 48 miteinander verrastet, wozu im hinteren Bereich seitlich an der oberen Gehäuseschale 20 Rastvorsprünge 90 angeformt sind, die in Rastaussparungen 92 im hinteren Bereich der Seitenwangen 52 der unteren Gehäuseschale 48 einrasten. Beim Aufsetzen des Oberteils 16 auf das Unterteil 18 dringen die Schneidklemmkontakte 62 des Kontaktträgers 58 in die Eintrittsschlitze 38 und 40 des Ladestückes 26 und kontaktieren dabei die Adern 12, die in den Bohrungen 34 und den Rinnen 36 des Ladestückes 26 angeordnet sind. Dadurch wird die leitende Verbindung zwischen den Adern über die Schneidklemmkontakte 62 zu den Verbinderkontakten 60 hergestellt.In the in FIG. 7 Thus, both the upper part 16 and the lower part 18 are fully assembled. It is now the upper part 16 is inserted into the lower part 18, wherein the side cheeks 24 of the upper housing shell 20 are inserted into the cutouts 54 of the side walls 52 of the lower housing shell 48. The side cheeks 24 and 52 are stepped at their circumference, so that between the side cheeks 24 and 52 is formed from the inside outward continuous butt joint. In the assembled state, the upper housing shell 20 and the lower housing shell 48 are locked together, for which purpose 20 locking projections 90 are integrally formed laterally on the upper housing shell, which engage in locking recesses 92 in the rear region of the side walls 52 of the lower housing shell 48. When putting on the upper part 16 on the lower part 18 penetrate the insulation displacement contacts 62 of the contact carrier 58 in the inlet slots 38 and 40 of the charging piece 26 and contact the cores 12, which are arranged in the bores 34 and the grooves 36 of the charging piece 26. As a result, the conductive connection between the wires is made via the insulation displacement contacts 62 to the connector contacts 60.

Beim Aufsetzen des Oberteils 16 auf das Unterteil 18 wird außerdem das Kabel 10 mit seinem freigelegten Schirmgeflecht 14 auf die Schirmabnahmelaschen 80 gedrückt. Dabei ist das Kabel 10 mit seinem Schirmgeflecht 14 einerseits durch die Mulde 42 der oberen Gehäuseschale 20 abgestützt und wird andererseits gegen die federnden Schirmabnahmelaschen 80 gedrückt. Dadurch wird ein guter leitender elektrischer Kontakt einerseits mit der oberen Gehäuseschale 20 und andererseits über die Schirmabnahmelaschen 80 mit dem Schirmblech 64 hergestellt. Über das einstückige Schirmblech 64 wird die Schirmung einerseits an die Kontaktbügel 74 weitergegeben, die mit der Schirmung eines eingesteckten Steckers in Kontakt kommen. Zum Anderen wird die Schirmung einstückig an die Kontaktfederlasche 76 weitergegeben.When placing the upper part 16 on the lower part 18, the cable 10 is also pressed with its exposed braid 14 on the Schirmabnahehtaschen 80. The cable 10 is supported with its braided shield 14 on the one hand by the trough 42 of the upper housing shell 20 and on the other hand pressed against the resilient Schirmabnahiltaschen 80. As a result, a good conductive electrical contact is made on the one hand with the upper housing shell 20 and on the other hand via the Schirmabnahiltaschen 80 with the shield plate 64. On the one-piece shield plate 64, the shield is on the one hand passed to the contact bracket 74, which come into contact with the shield of an inserted plug. On the other hand, the shield is transmitted in one piece to the contact spring tab 76.

In den Figuren 11 und 12 ist gezeigt, wie der Steckverbinder in eine Montageplatte 94 eingesetzt wird, die aus einem elektrisch leitenden Material besteht und auf Massepotential liegt. Die Montageplatte 94 kann beispielsweise die Frontplatte eines Patch-Panels oder die Montageplatte eines Gerätes sein.In the Figures 11 and 12 It is shown how the connector is inserted into a mounting plate 94, which consists of an electrically conductive material and is at ground potential. The mounting plate 94 may be, for example, the front panel of a patch panel or the mounting plate of a device.

Die Montageplatte 94 weist einen Ausschnitt auf, welcher im Querschnitt dem Querschnitt des Steckverbinders und insbesondere der Frontseite der unteren Gehäuseschale 48 entspricht. An der Oberseite der unteren Gehäuseschale 48 sind angrenzend an deren stirnseitige Vorderkante zwei äußere Anlagevorsprünge 96 angeformt. In einem der Materialstärke der Montageplatte 94 entsprechenden Abstand nach hinten versetzt ist ein Gegenvorsprung 98 auf der Oberseite der unteren Gehäuseschale 48 angeformt. Weiter sind an der Unterseite der Bodenplatte 50 in einem dem Gegenvorsprung 98 entsprechenden Abstand von der stirnseitigen Vorderkante der unteren Gehäuseschale 48 Anlagevorsprünge 100 angeformt. Der fertig montierte Steckverbinder wird in den Ausschnitt der Montageplatte 94 in folgender Weise eingesetzt. Zunächst wird die obere stirnseitige Kante der unteren Gehäuseschale 48 in den Ausschnitt eingeschoben und so nach oben geführt, daß sich die Anlagevorsprünge 96 an der Vorderseite der Montageplatte 94 und der Gegenvorsprung 98 an der Hinterseite der Montageplatte 94 befinden. Dann wird die untere stirnseitige Kante der Gehäuseschale 48 von hinten in den Ausschnitt der Montageplatte 94 eingedrückt, bis die unteren Anlagevorsprünge 100 an der Rückseite der Montageplatte 94 anliegen. Dabei greift die Kontaktfederlasche 76 in einen Randausschnitt 104 des Ausschnittes der Montageplatte 94 und wird durch die Unterkante dieses Randausschnittes 104 gegen die Bodenplatte 50 gedrückt. Die Kontaktfederlasche 76 rastet dann mit beiderseits an der Kontaktfederlasche 76 ausgebildeten Stufen 102 vor der Montageplatte 94 ein, wodurch der Steckverbinder vollständig in dem Ausschnitt der Montageplatte 94 eingerastet und gehalten ist. Soll der Steckverbinder aus der Montageplatte 94 wieder gelöst werden, so muß lediglich auf der Rückseite der Montageplatte 94 die Kontaktfederlasche 76 von Hand gegen die Bodenplatte 50 gedrückt werden, so dass die Stufen 102 der Kontaktfederlasche 76 aus dem diese Kontaktfederlasche 76 aufnehmenden Randausschnitt 104 herausgehoben werden.The mounting plate 94 has a cutout which corresponds in cross section to the cross section of the connector and in particular the front side of the lower housing shell 48. At the top of the lower housing shell 48, two outer abutment protrusions 96 are integrally formed adjacent to the front-side leading edge. In a material thickness of the mounting plate 94 corresponding distance offset backwards a counter-projection 98 is formed on the upper side of the lower housing shell 48. Next are at the bottom of the bottom plate 50 in one The abutment 98 corresponding distance from the front-side front edge of the lower housing shell 48 integrally formed abutment projections 100. The assembled connector is inserted into the cutout of the mounting plate 94 in the following manner. First, the upper end edge of the lower housing shell 48 is inserted into the cutout and guided upward so that the abutment protrusions 96 are located on the front of the mounting plate 94 and the counter projection 98 on the rear side of the mounting plate 94. Then, the lower end edge of the housing shell 48 is pressed from behind into the cutout of the mounting plate 94 until the lower abutment projections 100 abut the rear of the mounting plate 94. In this case, the contact spring tab 76 engages in a peripheral cutout 104 of the cutout of the mounting plate 94 and is pressed by the lower edge of this edge cutout 104 against the bottom plate 50. The contact spring tab 76 then engages with trained on both sides of the contact spring tab 76 stages 102 in front of the mounting plate 94, whereby the connector is completely engaged and held in the cutout of the mounting plate 94. If the connector from the mounting plate 94 are released again, so only on the back of the mounting plate 94, the contact spring tab 76 by hand against the bottom plate 50 are pressed so that the steps 102 of the contact spring tab 76 from this contact spring tab 76 receiving edge cutout 104 are lifted ,

Im montierten Zustand drückt die Kontaktfederlasche 76 des Schirmbleches 64 federnd gegen die Unterkante des Ausschnittes der Montageplatte 94 und stellt somit einen guten Massekontakt des Schirmbleches 64 her, wodurch auch der Massekontakt mit dem Schirmgeflecht 14 des Kabels 10 und einem eingesteckten Stecker hergestellt wird.In the assembled state, the contact spring tab 76 of the shield plate 64 presses resiliently against the lower edge of the cutout of the mounting plate 94 and thus provides a good ground contact of the shield plate 64, whereby the ground contact with the shield braid 14 of the cable 10 and an inserted plug is made.
