Description

Beschreibungdescription

Die Erfindung betrifft einen Abschirmkontakt zur Anbindung eines elektrisch abgeschirmten Steckergehäuses an ein mit mindestens einem abschirmenden Geflecht ausgerüstetes elektrisches Kabel.The invention relates to a Abschirmkontakt for connecting an electrically shielded connector housing to a equipped with at least one shielding braid electrical cable.

Ein derartiger Abschirmkontakt wird benötigt, um die abschirmende Wirkung gegen Störstrahlungen von abgeschirmten elektrischen Kabeln über eine Steckverbindung sicherzustellen.Such a shield contact is required to ensure the shielding effect against interference from shielded electrical cables via a plug connection.

Stand der TechnikState of the art

Es ist in vielerlei Versionen bekannt, Steckverbinder mit abschirmender Wirkung an die Abschirmung eines elektrischen Kabels anzubinden.
So ist in der US 6,783,397 ein Steckverbinder gezeigt, dessen zweitteiliges Abschirmgehäuse an seiner Kabelanschlussseite einen geriffelten Metallstreifen aufweist, der zur Sicherung des elektrischen Kabels um den Kabelmantel herumgebogen wird.
Weiterhin ist in der US 7,052,292 ein Steckverbinder mit einer Erdungsstruktur dargestellt, die letztlich einen ovalen Ring einnehmend, bzw. zu diesem zusammengebogen wird und die Abschirmung von hier zwei nebeneinander angeordneten differentiellen Signalleitungen kontaktiert. Wobei der Ring gleichzeitig zur Halterung der Signalleitungen dient.
It is known in many versions to connect connectors with shielding effect to the shield of an electrical cable.
So is in the US 6,783,397 a connector is shown, the two-part shielding case has on its cable connection side a grooved metal strip which is bent around the cable sheath to secure the electric cable.
Furthermore, in the US 7,052,292 a connector with a grounding structure is shown, which ultimately occupies an oval ring, or is bent together to this and contacted the shield from here two juxtaposed differential signal lines. Wherein the ring also serves to hold the signal lines.

Aufgabenstellungtask

Der Erfindung liegt die Aufgabe zugrunde, ein abgeschirmtes Steckergehäuse mit einem Abschirmkontakt der eingangs genannten Art dahingehend auszubilden, dass eine einfache, werkzeuglose Anbindung des Abschirmgeflechtes eines elektrischen Kabels an eine die Steckkontakte in einem Kontaktträger umgebende Abschirmhülse erfolgt.The invention has the object of providing a shielded connector housing with a shielding contact of the type mentioned in such a way that a simple, tool-free connection of Abschirmgeflechtes an electrical cable to a plug contacts in a contact carrier surrounding shielding takes place.

Diese Aufgabe wird dadurch gelöst, dass in dem Steckergehäuse ein Kontaktträger, umgeben von einer abschirmenden Hülse mit einem Kontaktteil angeordnet ist, mittels dem eine elektrisch leitende Verbindung zu der Abschirmung des elektrischen Kabels realisierbar ist, wobei das Kontaktteil mit einem Omega-ähnlich geformten Endstück die äußere Abschirmung oder die innere Abschirmung kontaktierend umfasst.This object is achieved in that in the plug housing, a contact carrier, surrounded by a shielding sleeve is arranged with a contact part, by means of which an electrically conductive connection to the shield of the electric cable can be realized, wherein the contact part with an omega-like shaped end piece outer shield or contacting the inner shield comprises.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2-3 angegeben.Advantageous embodiments of the invention are specified in claims 2-3.

Das hier gezeigte Steckergehäuse mit einer umgebenden Abschirmhülse ist zur Übertragung von abgeschirmten Signalleitungen und zur Weiterleitung von Versorgungsspannungen, bzw. Versorgungsströmen vorgesehen.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass die Abschirmhülse mit einem Abschirmkontakt ausgebildet ist, der zur Übergabe des Abschirmpotenziales auf den Steckverbinder einfach auf die Kabelabschirmung des abgeschirmten elektrischen Kabels aufgerastet wird. Dazu ist der Abschirmkontakt als dreiseitig freigestelltes Kontaktteil ausgebildet, dass durch ein einfaches und werkzeugloses Umbiegen auf die Kabelabschirmung mit einem sogenannten Omega-Endstück verklemmt wird. Das Omega-Endstück ist als etwa einen Dreiviertelkreis einnehmendes Rohrstück, mit nach außen weisenden Abbiegungen geformt, so dass ein dem griechischen Omega (Ω) entsprechender Querschnitt gebildet wird. Weiterhin ist in das Kontaktteil eine weitere dreiseitig freigeschnittene Kontaktlasche integriert, die eine zusätzliche Kontaktierung zulässt.
The connector housing shown here with a surrounding shielding sleeve is provided for the transmission of shielded signal lines and for the transmission of supply voltages or supply currents.
The advantages achieved by the invention are, in particular, that the shielding sleeve is formed with a Abschirmkontakt that is simply snapped onto the cable shield of the shielded electrical cable for transferring the Abschirmpotenziales on the connector. For this purpose, the shield contact is designed as a three-sided release contact part that is clamped by a simple and tool-free bending on the cable shield with a so-called omega-tail. The omega end piece is shaped as a roughly three-quarter-circle piece of pipe, with outward-pointing bends, so that a cross-section corresponding to the Greek omega (Ω) is formed. Furthermore, a further three-side cut-free contact tab is integrated into the contact part, which allows an additional contact.

Für die Anbindung des Steckverbinders an die Abschirmung des elektrischen Kabels mit dem Omega-Endstück können vorteilhaft mehrere Anschlussvarianten genutzt werden:

1.
Das Kontaktteil wirkt mit dem Omega-Endstück auf eine äußere Abschirmung eines elektrischen Kabels.
2.
Das Kontaktteil wirkt mit dem Omega-Endstück auf eine innere Abschirmung eines entsprechend ausgeführten elektrischen Kabels, wobei zwangsläufig die Lasche ebenfalls auf die innere Abschirmung wirkt.
3.
Das Kontaktteil wirkt mit dem Omega-Endstück auf die äußere Abschirmung und mit der Kontaktlasche auf die innere Abschirmung.
For the connection of the connector to the shielding of the electric cable with the omega end piece advantageously several connection variants can be used:
1.
The contact part acts with the omega end piece on an outer shield of an electric cable.
Second
The contact part acts with the omega end piece on an inner shield of a correspondingly designed electrical cable, whereby inevitably the tab also acts on the inner shield.
Third
The contact part acts with the omega end piece on the outer shield and with the contact lug on the inner shield.

Between the end piece 14 and its connection to the shielding sleeve 10, a virtually square surface 12 is provided with a three-sided exposed, pointing to the electrical cable contact tab 13 within the contact part, which ensures an additional contact with a common inner shield 8 of the signal lines 5 ,

Wie die Fig. 3b zeigt, ist das abgewinkelte Kontaktteil 11 so in Richtung des elektrischen Kabels 3 gebogen, dass das Endstück 14 hierbei mit seiner Omega-ähnlichen Struktur die Ummantelung 4 des elektrischen Kabels 3 mit einer klemmenden Wirkung umfasst.As shown in Fig. 3b, the angled contact member 11 is bent in the direction of the electric cable 3, that the end piece 14 in this case includes the sheath 4 of the electric cable 3 with a clamping effect with its omega-like structure.

Die Fig. 4a wiederum zeigt den Kontaktträger 2 mit dem elektrischen Kabel 3, welches unterhalb seiner äußeren Ummantelung 4 eine freigelegte, äußere Abschirmung 7 für das gesamte Kabel, und eine weitere, gemeinsame innere Abschirmung 8, nur für die Signalleitungen 5 aufweist.FIG. 4 a again shows the contact carrier 2 with the electrical cable 3, which has an exposed outer shield 7 for the entire cable underneath its outer casing 4, and a further, common inner shield 8, only for the signal lines 5.
