Description

Die Erfindung betrifft eine elektrische Steckverbindung nach dem Oberbegriff des Anspruchs 1, welche einen Steckverbinder, einen Gegenstecker und einen elektrisch leitfähigen Körper aufweist.The invention relates to an electrical connector according to the preamble of claim 1, which has a connector, a mating connector and an electrically conductive body.

Ein derartiger Steckverbinder umfasst ein Gehäuse zur Aufnahme elektrischer Steckerelemente, über welche ein elektrischer Kontakt mit einem Gegenstecker herstellbar ist, sowie eine Ziehhilfe aus einem elektrisch isolierenden Material, mittels welcher der Steckverbinder von einem Gegenstecker abziehbar ist und die in Form einer Lasche von dem Gehäuse des Steckverbinders absteht. Eine solche Ziehhilfe erleichtert das Ablösen des Steckverbinders von einem Gegenstecker, insbesondere in schwer zugänglicher Umgebung. Hierzu wird die von dem Gehäuse des Steckverbinders abstehende Ziehhilfe ergriffen und der Steckverbinder durch (manuelle) Ausübung einer entsprechenden Zugkraft auf die Ziehhilfe vom Gegenstecker abgezogen. Es ist daher nicht erforderlich, das Gehäuse des Steckverbinders selbst zu ergreifen, um diesen vom Gegenstecker abziehen zu können. Und es wird insbesondere vermieden, dass in beengten Einbausituationen versucht wird, den Steckverbinder durch Ausüben einer Zugkraft auf das zugeordnete Anschlusskabel vom Gegenstecker zu lösen, wodurch die Verbindung zwischen dem Steckverbinder und dem zugehörigen Anschlusskabel beschädigt werden könnte. Die Ziehhilfe dient somit gleichzeitig als Zugentlastung für das Kabel.Such a connector comprises a housing for receiving electrical connector elements, via which an electrical contact with a mating connector can be produced, and a pulling aid made of an electrically insulating material, by means of which the connector is removable from a mating connector and in the form of a tab of the housing of the Connector protrudes. Such a pulling aid facilitates the detachment of the connector from a mating connector, especially in hard to reach environment. For this purpose, the projecting from the housing of the connector pulling aid is taken and pulled off the connector by (manual) exercise of a corresponding tensile force on the pulling of the mating connector. It is therefore not necessary to take the housing of the connector itself, in order to deduct this from the mating connector can. And it is particularly avoided that in tight installation situations trying to release the connector by exerting a tensile force on the associated connection cable from the mating connector, whereby the connection between the connector and the associated connection cable could be damaged. The pulling aid thus serves as a strain relief for the cable.

Jedoch kann die Anordnung einer solchen Ziehhilfe am Steckverbinder mit dem Erfordernis kollidieren, an dem Steckverbinder eine Schirmauflage zur Verfügung zu stellen, an welcher der Schirm des dem Steckverbinder zugeordneten Anschlusskabels anliegt, um diesen auf ein definiertes Potential zu legen (Potentialsausgleich), wie etwa in der DE 20 2010 000 741 U1 beschrieben.However, the provision of such a pulling aid on the connector may conflict with the need to provide a shield pad on the connector to which the shield of the connector cable associated with the connector contacts to set it to a defined potential (potential equalization), such as in FIG of the DE 20 2010 000 741 U1 described.

In der US 2012/0171888 A1 ist eine Anordnung mit einem Gehäuse zur Aufnahme elektrischer Kontakte und mit einer an dem Gehäuse angeordneten Ziehhilfe beschrieben. In dem länglich ausgebildeten Körper der Ziehhilfe ist eine Aussparung ausgebildet, in welche ein plattenförmig ausgebildetes Schirmungsblech eingelegt werden kann.In the US 2012/0171888 A1 an arrangement is described with a housing for receiving electrical contacts and arranged on the housing with a pulling aid. In the elongated body of the pulling aid is a recess formed, in which a plate-shaped shielding plate can be inserted.

Die DE 20 2008 004 428 U1 beschreibt einen Steckverbinder der ein Gehäuse aufweist, das mit einer Schirmauflage versehen ist, welche zur Kontaktierung eines leitenden Elements im Bereich eines korrespondierenden Steckverbinders ausgebildet ist, wobei aus einer Haupterstreckungsebene der Schirmauflage einer oder mehrere Federkontakte vorstehen, die dazu ausgelegt sind, einen Abschnitt des zu kontaktierenden leitenden Elements im Bereich des weiteren Steckverbinders zu kontaktieren.The DE 20 2008 004 428 U1 describes a connector having a housing which is provided with a shield pad, which is designed for contacting a conductive element in the region of a corresponding connector, projecting from a main extension plane of the shield support one or more spring contacts, which are adapted to a portion of the contact contacting conductive element in the region of the other connector.

Weiter ist in der DE 10 2008 034 113 A1 eine Verbindungseinrichtung mit einem Steckverbinder und einer daran vorgesehenen Leiteranschlusseinrichtung zum Anschluss wenigstens eines Leiters sowie einem über eine Rasteinrichtung mit dem Steckverbinder verbundenen Abschirmblech zum Abschirmen der Leiteranschlusseinrichtung vorgesehen. Die Rasteinrichtung weist eine zu der Grundfläche des Abschirmblechs geneigt angeordnete Rasteinheit auf.Next is in the DE 10 2008 034 113 A1 a connection device with a connector and a conductor connection device provided thereon for connecting at least one conductor and a shield plate connected to the connector via a latching device for shielding the conductor connection device. The latching device has a latching unit which is inclined relative to the base surface of the shielding plate.

Der Erfindung liegt das Problem zugrunde, einen Steckverbinder mit Ziehhilfe der eingangs genannten Art weiter zu verbessern.The invention is based on the problem of further improving a connector with a pulling aid of the type mentioned.

Dieses Problem wird erfindungsgemäß durch die Schaffung einer elektrischen Steckverbindung mit den Merkmalen des Anspruchs 1 gelöst.This problem is inventively solved by the provision of an electrical connector with the features of claim 1.

Danach ist es bei einer gattungsgemäßen Steckverbindung vorgesehen, dass der elektrisch leitfähige Abschnitt mindestens einen Befestigungsabschnitt umfasst, der ein freies Ende der Ziehhilfe umgreift, wobei der elektrisch leitfähige Abschnitt weiter einen Oberflächenabschnitt bildet, an den der Schirm des elektrischen Anschlusskabels anlegbar ist.Thereafter, it is provided in a generic connector that the electrically conductive portion comprises at least one attachment portion which engages around a free end of the pulling aid, wherein the electrically conductive portion further forms a surface portion to which the screen of the electrical connection cable can be applied.

Die erfindungsgemäße Lösung beruht auf der Erkenntnis, dass eine Schirmauflage deshalb vorteilhaft in eine Ziehhilfe integriert werden kann, weil sich die Ziehhilfe gezielt so ausgestalten lässt, dass sich solche Bereiche der Ziehhilfe, die als Griffbereiche zum Erfassen der Ziehhilfe dienen, und solche Bereiche der Ziehhilfe, an denen die Schirmauflage vorgesehen ist, (räumlich) voneinander trennen lassen.The solution according to the invention is based on the recognition that a shield support can therefore advantageously be integrated into a pulling aid, because the pulling aid can be specifically designed such that those areas of the pulling aid which serve as gripping areas for detecting the pulling aid and those areas of the pulling aid , where the shield support is provided, can be separated (spatially) from each other.

So ist es vorteilhaft, die Schirmauflage in einem Bereich der Ziehhilfe vorzusehen, der dem vom Gehäuse des Steckverbinders abgehenden Anschlusskabel zugewandt ist, so dass sich in einfacher Weise ein zuverlässiger elektrischer Kontakt zwischen dem Schirm des Kabels und der Schirmauflage herstellen lässt. Hinsichtlich der Griffbereiche, an denen die Ziehhilfe von einem Nutzer ergriffen werden kann, ist es demgegenüber zweckmäßig, diese an solchen Bereichen der Ziehhilfe anzuordnen, die dem Anschlusskabel gerade nicht zugewandt sind, um das Ergreifen der Ziehhilfe durch einen Nutzer zu erleichtern und ein versehentliches Ziehen am Anschlusskabel zu vermeiden.Thus, it is advantageous to provide the shield support in a region of the pulling aid, which faces the outgoing from the housing of the connector connecting cable, so that can be produced in a simple manner, a reliable electrical contact between the shield of the cable and the shield support. With respect to the grip areas where the pull can be taken by a user, on the other hand, it is expedient to arrange them on those areas of the pulling aid, which are not facing the connection cable, to facilitate the gripping of the pulling aid by a user and accidental pulling to avoid on the connection cable.

Somit schafft die erfindungsgemäße Lösung einen vereinfachten Aufbau eines Steckverbinders, indem die Ziehhilfe und eine Schirmauflage zu einer Baugruppe zusammengefasst werden, ohne dass dies Einschränkungen hinsichtlich der Funktion der Ziehhilfe oder der Schirmauflage zur Folge hätte.Thus, the solution of the invention provides a simplified structure of a connector by the drawing aid and a shield support are combined to form an assembly, without this would have restrictions on the function of the drawing aid or the shield support.

Der als Schirmauflage dienende elektrisch leitfähige Abschnitt ist formschlüssig an der Ziehhilfe festgelegt. Hierzu umgreift der elektrisch leitfähige Abschnitt einen Befestigungsbereich der Ziehhilfe. Ergänzend kann eine kraftschlüssige und/oder stoffschlüssige Fixierung des elektrisch leitfähigen Abschnittes an der Ziehhilfe vorgesehen sein.The serving as a shield pad electrically conductive portion is positively secured to the pulling aid. For this purpose, the electrically conductive portion encompasses a fastening region of the pulling aid. In addition, a non-positive and / or cohesive fixation of the electrically conductive portion may be provided on the pulling aid.

Konkret kann es sich bei dem elektrisch leitfähigen Abschnitt um ein Blechteil handeln, das an der Ziehhilfe festgelegt wird, so dass es einen als Schirmauflage dienenden, elektrisch leitfähigen Oberflächenabschnitt an der Ziehhilfe definiert.Specifically, the electrically conductive portion may be a sheet metal part that is fixed to the pulling aid so that it defines an electrically conductive surface portion on the pulling aid that serves as a shielding pad.

Die Ziehhilfe selbst kann einstückig an dem Gehäuse des Steckverbinders angeformt oder als separates Bauteil hieran befestigt sein. Als Material für die Ziehhilfe eignet sich z.B. Kunststoff.The pulling aid itself can be integrally formed on the housing of the connector or attached thereto as a separate component. As a material for the drawing aid is suitable, for. Plastic.

Die Ziehhilfe weist vorteilhaft mindestens einen Griffbereich auf, an dem die Ziehhilfe ergriffen werden kann, um hierauf (manuell) eine Zugkraft auszuüben, mit der sich der Steckverbinder von einem Gegenstecker abziehen lässt, so dass die Steckverbindung gelöst wird. Ein solcher Griffbereich ist bevorzugt an einem Bereich der Ziehhilfe ausgebildet, der einem bestimmungsgemäß am Steckverbinder angeschlossenen Anschlusskabel nicht zugewandt ist, um das Ergreifen der Ziehhilfe zu erleichtern und zudem ein versehentliches Ziehen am Anschlusskabel zu vermeiden. Ein jeweiliger Griffbereich kann hierzu beispielsweise als eine Griffmulde, gegebenenfalls mit geriffelter Oberfläche, ausgebildet sein, die sich seitlich an der Ziehhilfe erstreckt. Insbesondere können zwei Griffmulden an je einer von zwei gegenüberliegenden Seiten der Ziehhilfe vorgesehen sein, wobei der als Schirmauflage dienende elektrisch leitfähige Oberflächenabschnitt vorteilhaft so zwischen den beiden Griffmulden positioniert ist, dass sich ein bestimmungsgemäß an dem Steckverbinder angeschlossenes elektrisches Kabel mit seinem Schirm an jenem Oberflächenabschnitt abstützt.The pulling aid advantageously has at least one grip area, on which the pulling aid can be grasped, in order to exert (manually) a tensile force with which the connector can be pulled off a mating connector, so that the plug connection is released. Such a grip region is preferably formed on a region of the pulling aid which does not face a connection cable connected as intended to the connector, in order to facilitate grasping the pulling aid and also to avoid accidental pulling on the connection cable. A respective one For this purpose, the grip region can be designed, for example, as a recessed grip, optionally with a ribbed surface, which extends laterally on the pulling aid. In particular, two recessed grips can be provided on each of two opposite sides of the pulling aid, wherein the electrically conductive surface portion serving as a shield support is advantageously positioned between the two recessed grips, that an intended purpose connected to the connector electrical cable is supported with its screen on that surface portion ,

Weiterhin sind an der Ziehhilfe elektrisch leitende Verbindungsmittel vorgesehen, über die der als Schirmauflage dienende, elektrisch leitfähige Abschnitt der Ziehhilfe mit einem elektrisch leitenden Körper verbindbar ist, um hierüber einen Potentialausgleich zwischen dem Schirm des dem Steckverbinder zugeordneten Anschlusskabels und jenem Körper zu erreichen. Hierbei kann es sich beispielsweise um eine (elektrisch leitfähige) Wand handeln, die einen Ausschnitt aufweist, durch welchen hindurch der Steckverbinder mit einem Gegenstecker zu verbinden ist, wobei letzterer an der besagten Wand festgelegt sein kann. Durch die Verbindung des Schirmes des dem Steckverbinder zugeordneten Anschlusskabels mit jener Wand - über die Schirmauflage am Steckverbinder sowie die hierfür vorgesehenen Verbindungsmittel - lässt sich ein definierter Potentialausgleich mit jener Wand herbeiführen.Furthermore, electrically conductive connecting means are provided on the drawing aid, via which the serving as a shield support, electrically conductive portion of the pulling aid with an electrically conductive body is connected in order to achieve an equipotential bonding between the screen of the connector associated connection cable and that body. This may be, for example, an (electrically conductive) wall having a cutout through which the connector is to be connected to a mating connector, the latter being fixed to said wall. By connecting the shield of the connecting cable associated with the connector with that wall - via the shield support on the connector and the connecting means provided for this purpose - a defined equipotential bonding can be brought about with that wall.

Die Verbindungsmittel, über welche die elektrische Verbindung der Schirmauflage mit einem weiteren (elektrisch leitfähigen) Körper, z. B. in Form einer Wand, erfolgen soll, können in unterschiedlicher Weise ausgestaltet sein. Eine Möglichkeit ist die Herstellung einer flexiblen Verbindung über ein elektrisches Kabel. Eine andere Möglichkeit ist die Herstellung einer Steckverbindung zwischen der Schirmauflage und dem weiteren Körper, insbesondere gleichzeitig beim Zusammenstecken des Steckverbinders mit einem Gegenstecker. Weiterhin kann ein elektrischer Kontakt auch an Befestigungsstellen hergestellt werden, an denen der Steckverbinder an jenem Körper zu befestigen ist.The connecting means, via which the electrical connection of the shield support with another (electrically conductive) body, for. B. in the form of a wall, can be configured in different ways. One possibility is to make a flexible connection via an electrical cable. Another possibility is the production of a plug connection between the shield support and the other body, in particular at the same time when plugging the connector with a mating connector. Furthermore, an electrical contact can also be made at attachment points at which the connector is to be attached to that body.

Figur 1 zeigt eine Steckeranordnung mit drei Steckverbindern 1, 1', 1", denen jeweils ein Gegenstecker 101, 101', 101" zugeordnet ist, und zwar im nicht zusammengesteckten Zustand. Jeder der Steckverbinder 1, 1', 1" ist zum Einstecken in einen der Gegenstecker 101, 101', 101" vorgesehen. Hierzu weisen die Steckverbinder 1, 1', 1" und die zugeordneten Gegenstecker 101, 101', 101" jeweils miteinander korrespondierende Steckerelemente auf, z. B. in Form von Steckerstiften aufseiten der Steckverbinder 1, 1',1" und in Form die Steckerstifte aufnehmender Steckerbuchsen aufseiten der Gegenstecker 101, 101', 101". FIG. 1 shows a plug assembly with three connectors 1, 1 ', 1 ", which in each case a mating connector 101, 101', 101" is assigned, in the unmated state. Each of the connectors 1, 1 ', 1 "is provided for insertion into one of the mating connectors 101, 101', 101". For this purpose, the connectors 1, 1 ', 1 "and the associated mating connector 101, 101', 101" in each case corresponding to one another connector elements, for. B. in the form of plug pins on the side of the connector 1, 1 ', 1 "and in the form of the plug pins female receptacles on the side of the mating connector 101, 101', 101".

Die Gegenstecker 101, 101', 101" sind vorliegend an einer Wand 100, z. B. einer Gerätewand, als einem elektrisch leitenden (z. B. metallischen) Körper angeordnet, und zwar derart, dass das Steckgesicht eines jeweiligen Gegensteckers 101, 101', 101" einem Ausschnitt 100a der Wand 100 zugewandt ist, durch welchen hindurch ein jeweiliger Gegenstecker 101, 101', 101" mit dem zugeordneten Steckverbinder 1, 1', 1" zusammensteckbar und damit elektrisch kontaktierbar ist.In the present case, the mating plugs 101, 101 ', 101 "are arranged on a wall 100, for example of a device wall, as an electrically conductive (eg metallic) body in such a way that the mating face of a respective mating plug 101, 101 ', 101 "facing a cutout 100a of the wall 100, through which a respective mating connector 101, 101', 101" with the associated connector 1, 1 ', 1 "can be plugged together and thus electrically contacted.

Im Weiteren geht es vorliegend um die Ausgestaltung der Steckverbinder 1, 1', 1", die jeweils ein Gehäuse 10, 10', 10" mit einer daran angeordneten Ziehhilfe 2, 2', 2" aufweisen. Diese Ausgestaltung wird nachfolgend am Beispiel eines der Steckverbinder (1) anhand Figur 2A näher beschrieben werden, wobei in den Figuren 4A bis 8A mögliche Abwandlungen jenes Steckverbinders dargestellt sind. Die Figuren 3A und 3B betreffen Details im Bereich der mit einer Schirmauflage versehenen Ziehhilfe eines Steckverbinders.In the present case, this concerns the design of the connectors 1, 1 ', 1 ", which each have a housing 10, 10', 10" with a pulling aid 2, 2 ', 2 "disposed thereon the connector (1) based FIG. 2A be described in more detail, wherein in the FIGS. 4A to 8A possible modifications of that connector are shown. The FIGS. 3A and 3B concern details in the area provided with a shield support pulling a connector.

Figur 2A zeigt von einer Steckeranordnung der in Figur 1 dargestellten Art einen Steckverbinder 1 zusammen mit der Wand 100 und einen hinter einem Ausschnitt der Wand 100 angeordneten, dem Steckverbinder 1 zugeordneten Gegenstecker 101. FIG. 2A shows from a plug assembly of in FIG. 1 shown type a connector 1 together with the wall 100 and arranged behind a section of the wall 100, the connector 1 associated mating connector 101st

Der Steckverbinder 1 weist ein Gehäuse 10 auf, dessen Vorderseite 12 als ein Steckgesicht mit Steckerelementen, hier in Form von Steckerstiften, ausgeführt ist, über die der Steckverbinder 1 mit dem zugeordneten Gegenstecker 101 zusammensteckbar ist. Dies erfolgt vorliegend konkret durch Einführen der Steckerelemente an der Vorderseite 12 des Steckverbinders 1 in Buchsenkontakte des Gegensteckers. Die Rückseite 14 des Steckergehäuses 10 ist als ein elektrischer Anschlussbereich ausgeführt, über den ein elektrisches Anschlusskabel an den Steckverbinder 1 anschließbar ist.The connector 1 has a housing 10, the front side 12 is designed as a mating face with connector elements, here in the form of connector pins, via which the connector 1 with the associated mating connector 101 is plugged together. In the present case, this takes place concretely by inserting the plug elements on the front side 12 of the plug connector 1 into socket contacts of the mating plug. The rear side 14 of the plug housing 10 is designed as an electrical connection area, via which an electrical connection cable can be connected to the plug connector 1.

Weiterhin steht von dem Steckverbinder 1, konkret von der Rückseite des Steckergehäuses 10, eine Ziehhilfe 2 ab, die hier als eine in Figur 3A in einer Draufsicht genauer erkennbare Lasche ausgeführt ist. Zwei weitere Ansichten der Ziehhilfe 2 finden sich in den Figuren 2B und 2C. Die Ziehhilfe 2 soll das Abziehen des Steckverbinders 1 von dem zugeordneten Gegenstecker 101 ermöglichen, wenn jene beiden Steckerteile 1, 101 zusammengesteckt sind. Hierzu ergreift ein Nutzer die Ziehhilfe 2 und übt auf diese eine Zugkraft aus, die den Steckverbinder 1 von dem Gegenstecker 101 löst. Für ein einfaches Ergreifen der Ziehhilfe 2 weist diese Griffbereiche 21, 22 in Form je einer (geriffelten) Griffmulde auf. Die beiden Griffbereiche 21, 22 sind einander gegenüberliegend an jeweils einer Seite der Ziehhilfe 2 angeordnet.Furthermore, from the connector 1, specifically from the back of the plug housing 10, a pulling aid 2 from, here as a in FIG. 3A in a plan view more recognizable tab is executed. Two other views of the pulling aid 2 can be found in the FIGS. 2B and 2C , The pulling aid 2 is to allow the removal of the connector 1 of the associated mating connector 101, when those two connector parts 1, 101 are plugged together. For this purpose, a user takes the pulling aid 2 and exerts on this a tensile force that releases the connector 1 of the mating connector 101. For easy gripping of the pulling aid 2, these grip areas 21, 22 in the form of one (serrated) recessed grip each. The two gripping areas 21, 22 are arranged opposite one another on each side of the pulling aid 2.

Die Ziehhilfe 2 besteht aus einem elektrisch isolierenden Material, insbesondere Kunststoff. Sie kann einstückig an dem Gehäuse 10 des Steckverbinders 1 angeformt oder als ein separates Bauteil hieran befestigt sein, z.B. durch Kleben, Verschrauben oder Verrasten. Im erstgenannten Fall sind am Steckverbinder 1 einerseits und an der Ziehhilfe 2 andererseits einander zugeordnete Klebeflächen vorgesehen. Im letztgenannten Fall sind am Steckverbinder 1 einerseits und an der Ziehhilfe 2 andererseits einander zugeordnete, miteinander in Eingriff bringbare Rastelemente angeordnet.The pulling aid 2 consists of an electrically insulating material, in particular plastic. It may be integrally formed on the housing 10 of the connector 1 or attached thereto as a separate component, e.g. by gluing, screwing or latching. In the former case, on the one hand and on the drawing aid 2, on the other hand, mutually associated adhesive surfaces are provided on the connector 1. In the latter case, on the one hand and on the drawing aid 2 on the other hand mutually associated, engageable with each other locking elements are arranged on the connector 1.

Die Ziehhilfe 2 ist dabei vorliegend derart am Steckverbinder 1 angeordnet, dass ein bestimmungsgemäß an den Anschlussbereich auf der Rückseite 14 des Steckergehäuses 10 angeschlossenes Anschlusskabel entlang einer jenem Kabel zugewandten Seite der Ziehhilfe 2 verläuft. Hierzu steht die Ziehhilfe 2 im Ausführungsbeispiel benachbart zu dem Anschlussbereich an der Rückseite 14 des Steckergehäuses 10 von letzterem ab. Gemäß Figur 2A befindet sich die Ziehhilfe 2 konkret unmittelbar unterhalb des an der Rückseite 14 des Steckergehäuses 10 vorgesehenen Anschlussbereiches für ein elektrisches Kabel. D. h., die dem Anschlusskabel zugewandte Seite der Ziehhilfe 2 kann als eine Auflage für jenes Anschlusskabel dienen.
In einer Doppelnutzung der Ziehhilfe 2 ist vorliegend auf deren einem (bestimmungsgemäß an den Steckverbinder 1 angeschlossenen) Anschlusskabel zugewandter Seite gemäß den Figuren 2A, 2B, 2C und 3A ein elektrisch leitfähiger Abschnitt 3 vorgesehen, der mit einem Oberflächenabschnitt 30 eine Schirmauflage für das Anschlusskabel bildet. Indem der Schirm eines bestimmungsgemäß an den Steckverbinder 1 angeschlossenen Anschlusskabels an jenen Oberflächenabschnitt 30 angelegt wird, kann der Schirm des Anschlusskabels hierüber mit einem weiteren Körper, z. B. der Wand 100, zu Zwecken eines Potentialausgleichs elektrisch leitend verbunden sein.
In Figur 3A ist schematisch ein Ausschnitt eines an den Steckverbinder 1 angeschlossenen Anschlusskabels 200 gezeigt, das mit seinem Schirm 203 am elektrisch leitfähigen Abschnitt 3 der Ziehhilfe 2 (Schirmauflage) bzw. im Ausführungsbeispiel genauer am besagten Oberflächenabschnitt 30 anliegt.
Der als Schirmauflage dienende elektrisch leitfähige Abschnitt 3 kann insbesondere aus Metall bestehen. Er wird vorliegend durch ein Blechteil gebildet.
Zur Fixierung des elektrisch leitfähigen Abschnittes 3 an der Ziehhilfe 2 dient im Ausführungsbeispiel eine formschlüssige Verbindung. So ist ein erster von dem elektrisch leitfähigen Abschnitt 3 abstehender Befestigungsabschnitt 33 durch eine Befestigungsöffnung 23 in der Ziehhilfe 2 hindurchgeführt und hintergreift diese mit abgewinkelten Enden 34 an ihrem Rand. Ein weiterer von dem elektrisch leitfähigen Abschnitt 3 abstehender Befestigungsabschnitt 35 umgreift die Ziehhilfe 2 an ihrem freien Ende 25, siehe auch Figur 3B.
Um über die an der Ziehhilfe 2 vorgesehene Schirmauflage, also über den elektrisch leitfähigen Abschnitt 3, den Schirm eines bestimmungsgemäß an den Steckverbinder 1 angeschlossenen elektrischen Kabels mit der Wand 100 zu verbinden, ist ein Verbindungsmittel erforderlich, über welches der elektrisch leitfähige Abschnitt 3 mit jener Wand 100 elektrisch kontaktierbar ist.
Gemäß dem in den Figuren 1 und 2A dargestellten Ausführungsbeispiel stehen von der Wand 100 Laschen 104 ab, die vorliegend aus dem Material der Wand 100 herausgeformt sind und die jeweils ein elektrisches Kontaktelement bilden, das je einem der Steckverbinder 1, 1', 1" zugeordnet ist, wenn dieser bestimmungsgemäß mit dem zugehörigen Gegenstecker 101, 101', 101" verbunden wird. Die Laschen 104 stehen dabei von der Wand 100 jeweils in Richtung auf die Steckverbinder ab; sie weisen also weg von den Gegensteckern 101, 101', 101".In the present case, the pulling aid 2 is arranged on the plug connector 1 in such a way that a connection cable connected as intended to the connection region on the rear side 14 of the plug housing 10 extends along a side of the pulling aid 2 facing that cable. For this purpose, the drawing aid 2 is adjacent to the connection region on the rear side 14 of the plug housing 10 of the latter in the exemplary embodiment. According to FIG. 2A Conveniently, the pulling aid 2 is located directly below the connection region for an electrical cable provided on the rear side 14 of the plug housing 10. That is, the Connecting cable facing side of the pulling aid 2 can serve as a support for that connection cable.
In a double use of the pulling aid 2 is present on the one (intended to connect to the connector 1) connecting cable side facing in accordance with the FIGS. 2A, 2B, 2C and 3A an electrically conductive portion 3 is provided, which forms with a surface portion 30 a shield support for the connection cable. By the screen of a purpose connected to the connector 1 connecting cable is applied to those surface portion 30, the shield of the connecting cable can be connected thereto with another body, for. B. the wall 100, be electrically connected for purposes of equipotential bonding.
In FIG. 3A schematically a section of a connected to the connector 1 connecting cable 200 is shown, which rests with its shield 203 on the electrically conductive portion 3 of the pulling aid 2 (shield support) or in the embodiment more precisely on said surface portion 30.
The electrically conductive section 3, which serves as a shield contact, can consist in particular of metal. He is presently formed by a sheet metal part.
For fixing the electrically conductive portion 3 to the pulling aid 2 is used in the embodiment, a positive connection. Thus, a first protruding from the electrically conductive portion 3 mounting portion 33 is passed through a mounting opening 23 in the pulling aid 2 and engages behind this with angled ends 34 at its edge. Another protruding from the electrically conductive portion 3 mounting portion 35 engages the pulling aid 2 at its free end 25, see also FIG. 3B ,
In order to connect via the provided on the pulling aid 2 shield support, so on the electrically conductive portion 3, the screen of a properly connected to the connector 1 electrical cable to the wall 100, a connecting means is required, via which the electrically conductive portion 3 with that Wall 100 is electrically contacted.
According to the in the FIGS. 1 and 2A illustrated embodiment are from the wall 100 tabs 104, which in the present case of the material of the wall 100th are formed and each forming an electrical contact element, which is assigned to each one of the connectors 1, 1 ', 1 "when this is intended to the corresponding mating connector 101, 101', 101" is connected. The tabs 104 are thereby from the wall 100 in each case in the direction of the connector from; So they point away from the mating connectors 101, 101 ', 101 ".

Am Steckverbinder 1, genauer an dessen Gehäuse 10 bzw. konkret an der Ziehhilfe 2, vgl. Figuren 2B und 2C, ist dementsprechend ein elektrischer (metallischer) Gegenkontakt 4 angeordnet, der mit dem als Schirmauflage dienenden elektrisch leitfähigen Abschnitt 3 über einen elektrischen Verbindungsabschnitt 36 in elektrischer Verbindung steht, z. B. durch einstückige Verbindung hiermit. So können der als Schirmauflage dienende Abschnitt 3 und der Gegenkontakt 4 durch ein einheitliches Blechteil gebildet werden. Entsprechendes gilt für die nachfolgend anhand der Figuren 4A bis 7C beschriebenen weiteren Ausführungsbeispiele. Der Gegenkontakt 4 liegt an dem wandseitigen Kontaktelement (in Form einer Lasche 104) an, wenn der Steckverbinder 1 mit dem zugehörigen Gegenstecker 101 verbunden ist. Hierdurch ist über den als Schirmauflage dienenden elektrisch leitfähigen Abschnitt 3, den Gegenkontakt 4 und das wandseitige Kontaktelement 104 eine elektrisch leitende Verbindung zwischen dem Schirm eines an den Steckverbinder 1 angeschlossenen Kabels und der Wand 100 herstellbar.On the connector 1, more precisely on the housing 10 or concretely on the pulling aid 2, cf. FIGS. 2B and 2C , Accordingly, an electrical (metallic) mating contact 4 is arranged, which is in electrical connection with the electrically conductive portion 3 serving as a screen support via an electrical connection portion 36, for. B. by integral connection hereby. Thus, serving as a shield support portion 3 and the mating contact 4 can be formed by a single sheet metal part. The same applies to the following with reference to the FIGS. 4A to 7C described further embodiments. The mating contact 4 is applied to the wall-side contact element (in the form of a tab 104) when the connector 1 is connected to the associated mating connector 101. As a result, an electrically conductive connection between the shield of a cable connected to the connector 1 and the wall 100 can be produced via the electrically conductive section 3, the mating contact 4 and the wall-side contact element 104 serving as the shield contact.

In den Figuren 4A bis 7C sind unterschiedliche Abwandlungen der anhand der Figuren 1 und 2 beschriebenen Kontaktierungsmöglichkeit dargestellt. Und die Figuren 8A bis 8C zeigen, zusammen mit Figur 3B, die Möglichkeit einer elektrischen Verbindung über ein Verbindungskabel.In the FIGS. 4A to 7C are different variations of the basis of the FIGS. 1 and 2 described contacting possible. And the FIGS. 8A to 8C show, along with FIG. 3B , the possibility of an electrical connection via a connecting cable.

Es werden nun zunächst die in den Figuren 4A bis 7C dargestellten Abwandlungen der anhand der Figuren 1, 2A, 2B und 2C erläuterten Kontaktierungsmöglichkeit beschrieben werden, wobei in den Figuren 4A bis 7C übereinstimmende Elemente mit den gleichen Bezugszeichen versehen sind wie in den Figuren 1, 2A, 2B und 2C und nachfolgend jeweils nur auf die Unterschiede zu den Figuren 1, 2A, 2B und 2C eingegangen wird.It will now first in the FIGS. 4A to 7C illustrated modifications of the basis of FIGS. 1 . 2A, 2B and 2C described contacting possibility are described, wherein in the FIGS. 4A to 7C matching elements are provided with the same reference numerals as in the FIGS. 1 . 2A, 2B and 2C and subsequently only on the differences to the FIGS. 1 . 2A, 2B and 2C will be received.

Gemäß der in Figur 4A dargestellten Ausführungsform weisen die als wandseitige Kontaktelemente dienenden, an der Wand 100 angeformten Laschen 105 weg von dem jeweils zugeordneten Steckverbinder (z. B. 1) und stattdessen in Richtung auf den entsprechenden Gegenstecker (z. B. 101). Die jeweilige Lasche 105 steht dabei vom Rand des Ausschnittes 100a der Wand 100 ab. An dem Steckverbinder 1 bzw. der Ziehhilfe 2 ist ein federnder Gegenkontakt 5 vorgesehen, der einerseits mit dem als Schirmauflage dienenden Abschnitt 3 elektrisch verbunden ist, vgl. die Einzeldarstellung der Ziehhilfe 2 in den Figuren 4B und 4C, und der andererseits derart von dem Steckverbinder 1 bzw. dessen Gehäuse 10 absteht, dass er an dem zugehörigen wandseitigen Kontaktelement (Lasche 105) unter elastischer Vorspannung anliegt, wenn der Steckverbinder 1 bestimmungsgemäß mit dem Gegenstecker 101 zusammengesteckt ist.According to the in FIG. 4A In the embodiment shown, the tabs 105, which are used as wall-side contact elements and are formed on the wall 100, face away from the respectively assigned connector (eg 1) and instead in the direction of the corresponding mating connector (eg 101). The respective tab 105 projects from the edge of the cutout 100a of the wall 100. At the connector 1 and the Pulling aid 2, a resilient mating contact 5 is provided, which is on the one hand electrically connected to the serving as a shield pad section 3, see. the individual representation of the pulling aid 2 in the Figures 4B and 4C and on the other hand so protrudes from the connector 1 and its housing 10 that it rests against the associated wall-side contact element (tab 105) under elastic bias when the connector 1 is properly mated with the mating connector 101.

Beim Ausführungsbeispiel der Figur 5A ist das wandseitige Kontaktelement als eine Kontaktöffnung 106 in der Wand 100 ausgebildet, welcher steckverbinderseitig wiederum ein federelastischer Gegenkontakt 6 zugeordnet ist, der mit dem als Schirmauflage dienenden Abschnitt 3 in elektrischer Verbindung steht, vgl. die Einzeldarstellung der Ziehhilfe 2 in den Figuren 5B und 5C. Der federelastische Gegenkontakt 6 steht derart von dem Steckverbinder 1 bzw. konkret von der Ziehhilfe 2 ab, dass er mit der wandseitigen Kontaktöffnung 106 in Eingriff tritt, wenn der Steckverbinder 1 bestimmungsgemäß mit dem Gegenstecker 101 verbunden wird. Hierbei liegt der federelastische Gegenkontakt 6 unter Vorspannung am Rand der wandseitigen Kontaktöffnung 106 an, so dass ein zuverlässiger elektrischer Kontakt besteht.In the embodiment of FIG. 5A the wall-side contact element is formed as a contact opening 106 in the wall 100, which in turn connector-side associated with a resilient mating contact 6, which is in electrical connection with the serving as a screen support portion 3, see. the individual representation of the pulling aid 2 in the Figures 5B and 5C , The resilient mating contact 6 is such from the connector 1 or concretely from the pulling aid 2 from that it comes into engagement with the wall-side contact opening 106 when the connector 1 is intended to be connected to the mating connector 101. Here, the resilient mating contact 6 is biased on the edge of the wall-side contact opening 106, so that there is a reliable electrical contact.
