Abstract

A multiwire shielded cable (14) for a data network is for example pre-installed in the wall (45) of a building. The end of the cable (14) enters a housing part (66) and is coupled to a Western connector (10) or another connector having a similar design, whatever the connector system that will be later used. When the user-specific equipment is later installed, a modular housing (29) is inserted into the housing part (66). The modular housing (29) has an input tip jack compatible with the connector (10) and another tip jack on the side of the user which may be a jack of the Western type, an IBM data jack or a BNC jack (27). The connector (10) is provided with a metallic shield which directly contacts the shielding of the cable (14) and the metallic shield of the input tip jack, which in turn is electrically connected to the metallic modular housing (29). An easily adaptable data installation system is thus obtained, in which the area from the end of the cable to the user-specific tip jack (27) is very effectively protected against perturbing radiation.

Eine Vorrichtung dieser Art ist aus der EP-A-0 231 539 bekannt.A device of this type is known from EP-A-0 231 539.

Bekannt ist ebenfalls, daß das Kabel beispielsweise in der Wand eines Gebäudes vorinstalliert ist, wobei sein Ende in einer Mauerdose mündet. Je nach dem zu installierenden Datennetz sind systemcharakteristische Datensteckbuchsen in der Mauerdose anzubringen und mit dem Kabel elektrisch zu verbinden. So gibt es solche Steckbuchsen für das IBM-System, oder für das Western-System, oder man braucht BNC-Buchsen. Um die Installation zu vereinfachen, wird mit dem Kabel eine erste, stets einheitliche Steckerhälfte verbunden, zu der eine ebenfalls stets einheitliche zweite Steckerhälfte des Steckadapters paßt. Somit kann die erste Steckerhälfte sofort installiert werden, unabhängig davon, welches Datensystem später verwendet werden soll. Es ist dann später nur erforderlich, einen Steckadapter einzustecken, dessen dritte Steckerhälfte den gewünschten Buchsentyp darstellt. So einfach, wie dadurch die Installation eines Datensystems ist, so einfach ist auch die Umstellung von einem System auf ein anderes. Es braucht nur der Steckadapter ausgetauscht zu werden.It is also known that the cable is pre-installed, for example, in the wall of a building, with its end ending in a wall box. Depending on the data network to be installed, system-specific data sockets must be fitted in the wall socket and electrically connected to the cable. So there are such sockets for the IBM system, or for the Western system, or you need BNC sockets. In order to simplify the installation, a first, always uniform plug half is connected to the cable, to which a likewise always uniform second plug half of the plug adapter fits. This means that the first half of the connector can be installed immediately, regardless of which data system is to be used later. It is then only necessary later to insert a plug adapter, the third half of which represents the desired socket type. So easy, as it makes the installation of a data system, so easy is the change from one system to another. Only the plug adapter needs to be replaced.

The second connector half is formed by several (8) conductor tracks arranged side by side directly on the circuit board. One edge strip is thus designed as a flat plug.

Problematisch bei dieser bekannten Vorrichtung ist, daß die elektrische Abschirmung im Übergangsbereich zwischen Kabel und zweiter Steckerhälfte (den Leiterbahnen der Schaltplatine) nur durch das notwendigerweise recht großvolumige metallische Installationsgehäuse bewirkt wird. Dieses muß recht aufwendig ausgeführt sein, um die hohen Anforderungen für leistungsfähige Datennetze zu erfüllen. Dennoch ist die Güte der Abschirmung wegen des großen Abstandes zwischen den Gehäusewänden und den Federzungen/Leiterbahnen der ersten und zweiten Steckerhälfte begrenzt.The problem with this known device is that the electrical shielding in the transition area between the cable and the second connector half (the conductor tracks of the circuit board) is only effected by the necessarily quite large-volume metallic installation housing. This must be carried out in a very complex manner in order to meet the high requirements for high-performance data networks. Nevertheless, the quality of the shielding is limited due to the large distance between the housing walls and the spring tongues / conductor tracks of the first and second connector halves.

Ein Stecker der einleitungsweise erwähnten Bauart ist als sogenannter WESTERN-Stecker (da von der Firma Western-Electric auf den Markt gebracht) bekannt. Gleichwohl verwendet die Erfindung vorzugsweise einen Stecker nur von prinzipiell ähnlicher Art, als nämlich seine Abmessungen derart modifiziert sind, daß Kabeladern größeren Durchmessers angeschlossen werden können. Bezüglich der Steckbuchse gilt sinngemäß das Gleiche.A plug of the type mentioned in the introduction is known as a so-called WESTERN plug (since it was brought onto the market by Western-Electric). Nevertheless, the invention preferably uses a plug only of a basically similar type, namely that its dimensions are modified in such a way that cable cores of larger diameter can be connected. The same applies analogously to the socket.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Aufgabe der Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art zu schaffen, die eine höherwertige elektrische Abschirmung ermöglicht. Weiterhin soll die Handhabung bei der Installation vereinfacht werden, die Bauteile sollen praxisgerecht und preiswert sein.The object of the invention is to provide a device of the generic type which enables higher-quality electrical shielding. Furthermore, the handling during installation should be simplified, the components should be practical and inexpensive.

Diese Aufgabe wird dadurch gelöst, daß sie einen Steckadapter umfaßt, wobei der Steckadapter - auf an sich bekannter Weise - einerseits die zweite Steckerhälfte und andererseits eine dritte Steckerhälfte aufweist, wobei Kontakte der zweiten und dritten Steckerhälfte - auf an sich bekannter Weise - mittels einer Schaltplatine des Steckadapters in vorbestimmter Weise elektrisch verbunden sind, und weiteres dadurch, daß die Schaltplatine mit der Steckbuchse und der dritten Steckerhälfte in einem wenigstens annähernd hohlprismatischen Modulgehäuse angeordnet ist, wobei von einer rückwärtigen Öffnungsseite die Steckbuchse und von der gegenüberliegenden vorderen Öffnungsseite die dritte Steckerhälfte zugänglich ist, und das Modulgehäuse in unmittelbar elektrisch leitender Berührung mit der Metallabschirmung der Steckbuchse steht.This object is achieved in that it comprises a plug adapter, the plug adapter - in a manner known per se - on the one hand having the second connector half and on the other hand a third connector half, contacts of the second and third connector halves - in a manner known per se - by means of a circuit board of the plug adapter are electrically connected in a predetermined manner, and further in that the circuit board with the socket and the third connector half is arranged in an at least approximately hollow prismatic module housing, the connector socket being accessible from a rear opening side and the third connector half being accessible from the opposite front opening side , and the module housing is in direct electrically conductive contact with the metal shield of the socket.

Der Vorteil der Erfindung liegt einerseits darin, daß der Stecker weniger Platz beansprucht, so daß im Austrittsbereich des Kabels, das heißt, in der normalerweise dort anzubringenden Mauerdose, mehr Platz für das Kabel bleibt. Dieses kann dann einfacher gehandhabt werden. Vor allem erfolgt die elektrische Abschirmung im Übergangsbereich vom Kabel bis zur zweiten Steckerhälfte (der Steckbuchse) in engem Abstand zu den stromführenden Bahnen, was einen ausgezeichneten Schutz gegen Störeinflüsse bedeutet.The advantage of the invention is, on the one hand, that the plug takes up less space, so that more space for the cable remains in the outlet region of the cable, that is to say in the wall socket which is normally to be fitted there. This can then be handled more easily. Above all, the electrical shielding takes place in the transition area from the cable to the second half of the connector (the socket) at a short distance from the current-carrying tracks, which means excellent protection against interference.

Damit wird auch der Übergangsbereich zur dritten Steckerhälfte abgeschirmt, wobei jedoch das Modulgehäuse erst bei der Installation des gewünschten Moduls in Erscheinung tritt, nicht schon bei der Kabelinstallation. Es ist daher auch möglich, den verschiedenen Steckadaptern (die sich in der Art der dritten Steckerhälfte unterscheiden) jeweils spezifisch angepaßte Modulgehäuse zuzuordnen, wodurch die Abschirmqualität optimiert werden kann. So ist beispielsweise eine IBM-Datensteckbuchse (als dritte Steckerhälfte) erheblich größer, als eine BNC-Buchse. Bei einem einheitlichen Abschirmgehäuse, das auf die größte Buchse abgestimmt sein müßte, ergäben sich große Fenster, wenn dann nur eine kleine Buchse zur Anwendung kommt. Durch ein solches Fenster kann dann Störstrahlung eindringen oder es sind zusätzliche Abschirmmasken vorzusehen. Diesen Nachteil vermeidet die erfindungsgemäße Ausgestaltung.This also shields the transition area to the third connector half, but the module housing only appears when the desired module is installed, not when the cable is installed. It is therefore it is also possible to assign the different plug-in adapters (which differ in the type of the third connector half) to specifically adapted module housings, whereby the shielding quality can be optimized. For example, an IBM data connector (as the third connector half) is considerably larger than a BNC connector. With a uniform shielding housing, which should be matched to the largest socket, large windows would result if only a small socket was used. Interference radiation can then penetrate through such a window or additional shielding masks must be provided. The configuration according to the invention avoids this disadvantage.

Eine weitere Ausgestaltung der Erfindung besteht darin, daß die Innenfläche des Modulgehäuses mehrere wulstartige Erhebungen aufweist, die an der Metallabschirmung der Steckbuchse, diese leicht elastisch verformend, anliegen. Hierdurch wird eine beim Einbau in das Modulgehäuse sich automatisch ergebende Kontaktierung erreicht. Die Erhebungen ergeben mehrere Kontaktpunkte, die einen höheren Kontaktdruck gewährleisten, so daß auch Fett- oder Oxidschichten die einwandfreie Kontaktierung nicht beeinträchtigen.A further embodiment of the invention is that the inner surface of the module housing has a plurality of bead-like elevations which bear against the metal shielding of the socket, which deforms it slightly elastically. In this way, contacting which automatically results when installed in the module housing is achieved. The surveys result in several contact points, which ensure a higher contact pressure, so that even grease or oxide layers do not impair the perfect contact.

Wenn auch weitere wulstartige Erhebungen an einem Metallteil der dritten Steckerhälfte anliegen, ist deren Abschirmung ebenfalls sicher kontaktiert.If there are further bead-like elevations on a metal part of the third connector half, their shielding is also securely contacted.

Eine Ausführungsform der Erfindung besteht darin, daß das Modulgehäuse auf einen etwa scheibenförmigen Tragrahmen aufklipsbar ist, so daß die vordere Öffnungsseite in Randnähe angeordnet ist und die rückwärtige Öffnungsseite etwa im Bereich des Scheibenzentrums, welcher Tragrahmen eine plane Basisebene aufweist. Der Tragrahmen ist dazu bestimmt und eingerichtet, an einer Wand oder einem Kabelkanal flach aufliegend befestigt zu werden, so daß er die dort vorliegende Öffnung umgibt, aus der das Kabel ausmündet. Er dient dann als Befestigungsbasis für ein Gehäuseteil, das den installierten Steckadapter samt Modulgehäuse einschließt. Das Modulgehäuse, in dem der gewünschte Steckadapter angeordnet ist, wird vom Tragrahmen allein gehalten, das heißt, schon bei noch nicht montiertem Gehäuseteil. Dieses kann somit auch, ohne daß an der elektrischen Installation etwas zu ändern wäre, ausgetauscht werden - etwa, wenn ein anderes Design gewünscht wird.One embodiment of the invention is that the module housing can be clipped onto an approximately disc-shaped support frame, so that the front opening side is arranged near the edge and the rear opening side approximately in the area of the pane center, which support frame has a flat base plane. The support frame is intended and set up to be attached to a wall or a cable duct lying flat, so that it surrounds the opening there, from which the cable opens. It then serves as a mounting base for a housing part that includes the installed plug-in adapter including the module housing. The module housing, in which the desired plug-in adapter is arranged, is held by the support frame alone, that is, even when the housing part has not yet been installed. This can also be replaced without having to change the electrical installation - for example, if a different design is required.

Eine Weiterbildung besteht darin, daß die Längsachse des hohlprismatischen Modulgehäuses gegenüber der Scheibenebene um einen kleinen Neigungswinkel geneigt ausgerichtet ist, so daß der untere Rand der rückwärtigen Öffnungsseite in geringerem Abstand zur Scheibenachse liegt, als der untere Rand der vorderen Öffnungsseite. Der Vorteil dieser Maßnahme besteht darin, daß einerseits die dritte Stekkerhälfte von dem ihr zugehörenden Stecker besser erreicht wird, andererseits vor allem aber das mit der ersten Steckerhälfte verbundene Kabel mit einem kürzeren Bogen aus der Wand austreten kann. Es empfiehlt sich dabei ein Neigungswinkel zwischen 10 und 20 Grad.A further development is that the longitudinal axis of the hollow prismatic module housing is inclined by a small angle of inclination with respect to the plane of the pane, so that the lower edge of the rear opening side lies at a smaller distance from the pane axis than the lower edge of the front opening side. The advantage of this measure is that, on the one hand, the third connector half is better reached by the plug belonging to it is, on the other hand, but especially the cable connected to the first connector half can emerge from the wall with a shorter arc. We recommend an angle of inclination between 10 and 20 degrees.

Eine Ausgestaltung kennzeichnet sich dadurch, daß am unteren Rand der rückwärtigen Offnungsseite des Modulgehäuses wenigstens ein etwa parallel zur Längsachse nach rückwärts abstehender erster Vorsprung ausgebildet ist und am unteren Rand der vorderen Öffnungsseite wenigstens ein quer zur Längsachse nach unten abstehender zweiter Vorsprung vorgesehen ist, an dessen freiem Ende ein parallel zur Längsachse nach vorwärts weisender Rastnocken ausgebildet ist. Damit läßt sich das Modulgehäuse in ergonomisch günstiger Weise am Tragrahmen fixieren und auch wieder davon lösen.An embodiment is characterized in that at least one first protrusion protruding rearward approximately parallel to the longitudinal axis is formed on the lower edge of the rear opening side of the module housing and at least one second protrusion protruding downwards transversely to the longitudinal axis is provided on the lower edge of the front opening side free end is formed a parallel to the longitudinal axis forward locking cams. This allows the module housing to be fixed to the support frame in an ergonomically advantageous manner and also detached therefrom.

Eine weitere Ausgestaltung besteht darin, daß der Tragrahmen von einer Randkante aus bis etwa zur Mitte reichend eine Auflagefläche für das Modulgehäuse aufweist, daß an der Innenkante der Auflagefläche wenigstens eine bügelartige Ausbildung vorgesehen ist, unter die der erste Vorsprung führend einschiebbar ist und daß nahe der äußeren Randkante wenigstens eine Öffnung vorgesehen ist, in die der zweite Vorsprung eintauchen kann, wobei der Rastnocken unter der Auflagefläche den unteren vorderen, elastisch ausweichend ausgebildeten Rand der Öffnung überrastet.A further embodiment consists in that the support frame has a support surface for the module housing extending from an edge to approximately the middle, that at least one bow-like design is provided on the inner edge of the support surface, under which the first projection can be inserted and near the outer edge at least one opening is provided, into which the second projection can dip, wherein the latching cam engages under the bearing surface the lower front, elastically evasive edge of the opening.

Eine weitere Ausgestaltung der Erfindung besteht darin, daß ein rahmenartiger Gehäuseteil auf den Tragrahmen aufklipsbar ist, welcher Gehäuseteil vier jeweils von der Basisebene des Tragrahmens etwa senkrecht hochstehende Rahmenwände aufweist, die gleich hoch sind, wobei der Tragrahmen von den Rahmenwänden umschlossen wird.A further embodiment of the invention consists in that a frame-like housing part can be clipped onto the support frame, which housing part has four frame walls which project approximately perpendicularly from the base plane of the support frame has, which are the same height, wherein the support frame is enclosed by the frame walls.

Diese Form schafft Platz für das durch den Tragrahmen reichende Kabel und das einzusetzende Modulgehäuse. Auch ergibt dies eine ästhetisch klare Gestaltung.This shape creates space for the cable reaching through the support frame and the module housing to be used. This also results in an aesthetically clear design.

Eine bevorzugte Weiterbildung besteht darin, daß ein Deckelteil vorgesehen ist, mit einer Deckfläche, zwei an gegenüberliegenden Seitenkanten angeordneten Seitenflächen, einer Vorderfläche und einer Rückfläche, wobei im Bereich der Rückfläche eine Gelenkvorrichtung zwischen Deckelteil und dem rahmenartigen Gehäuseteil ausgebildet ist und die Seitenflächen des Deckelteils etwa dreieckförmig gestaltet sind, so daß die Deckfläche schräg zur Basisebene ausgerichtet ist, wenn die Rahmenwände des rahmenartigen Gehäuseteils und die Seitenflächen des Deckelteils miteinander fluchtend aufeinander stoßen. Diese Deckelausbildung schafft zusätzlichen Platz im Gehäuse, unterstützt die schräge Lage des Modulgehäuses und kommt ästhetischen Vorgaben entgegen.A preferred further development is that a cover part is provided, with a cover surface, two side surfaces arranged on opposite side edges, a front surface and a rear surface, wherein in the area of the rear surface an articulated device is formed between the cover part and the frame-like housing part and the side surfaces of the cover part approximately are triangular in shape so that the top surface is oriented obliquely to the base plane when the frame walls of the frame-like housing part and the side surfaces of the cover part abut one another in alignment. This cover design creates additional space in the housing, supports the inclined position of the module housing and accommodates aesthetic requirements.

Gemäß einer Ausgestaltung hierzu ist vorgesehen, daß die rechteckige Vorderfläche des Deckelteils einen ersten randoffenen Ausschnitt aufweist.According to an embodiment of this, it is provided that the rectangular front surface of the cover part has a first cutout that is open at the edge.

Damit kann bei geschlossenem Deckelteil ein Stecker in die dritte Steckerhälfte eingesteckt bleiben. Deren Kabel kann durch den Ausschnitt aus dem Gehäuse treten.This means that when the cover part is closed, a connector can remain inserted in the third connector half. The cable can pass through the cutout from the housing.

In einer Weiterbildung ist vorgesehen, daß die an die Vorderfläche des Deckelteils anschließende Rahmenwand des rahmen-förmigen Gehäuseteils einen zweiten randoffenen Ausschnitt aufweist, der sich mit dem ersten Ausschnitt zu einem Gesamtausschnitt ergänzt.In a further development it is provided that the frame wall of the frame-shaped housing part has a second edge-open cutout that complements the first cutout to form an overall cutout.

Es ist weiterhin vorgesehen, daß der Tragrahmen mit seiner Basisebene auf einer Wand aufliegend daran befestigbar ist und der Tragrahmen mit einem daran aufgeklipsten Modulgehäuse vom rahmenartigen Gehäuseteil und Deckelteil eingeschlossen wird, wobei die dritte Steckerhälfte durch den ersten oder zweiten Ausschnitt oder durch den Gesamtausschnitt für eine dazu kongruente vierte Steckerhälfte zugänglich ist.It is further provided that the support frame can be fastened to it with its base plane lying on a wall and the support frame with a module housing clipped onto it is enclosed by the frame-like housing part and cover part, the third connector half being covered by the first or second cutout or by the overall cutout for one congruent fourth connector half is accessible.

Vorzugsweise besteht eine weitere Ausgestaltung darin, daß mehrere verschieden ausgerüstete Modulgehäuse vorgesehen sind, bei denen jeweils die zweite Steckerhälfte gleich ausgebildet ist und die dritte Steckerhälfte jeweils verschiedenartig. Dies bewirkt die eingangs genannte Systemvariabilität.A further embodiment preferably consists in that several differently equipped module housings are provided, in each of which the second connector half is of identical design and the third connector half is different in each case. This causes the system variability mentioned at the beginning.

Dabei ist vorgesehen, daß die dritte Steckerhälfte entweder eine BNC-Buchse, oder eine WESTERN-Buchse oder eine IBM-Datenbuchse ist.It is provided that the third connector half is either a BNC socket, or a WESTERN socket or an IBM data socket.

Dabei können auch zwei WESTERN-Buchsen mit einer zweiten Steckerhälfte gemeinsam auf einer Schaltplatine angeordnet sein.Two WESTERN sockets with a second connector half can also be arranged together on a circuit board.

Gleichermaßen können auch zwei BNC-Buchsen mit einer zweiten Steckerhälfte gemeinsam auf einer Schaltplatine angeordnet sein. Eine solche Tandemausführung ist mit IBM-Datenbuchsen nicht möglich, wegen deren größerem Platzbedarf.Similarly, two BNC sockets with a second connector half can be arranged together on a circuit board. Such a tandem version is not possible with IBM data sockets because of their larger space requirement.

Vorteilhafterweise ist auch vorgesehen, daß der Tragrahmen zur Aufnahme von zwei mit geringem Abstand parallel nebeneinanderliegenden Modulgehäusen eingerichtet ist, wobei der Tragrahmen aus elektrisch isolierendem Material besteht.Advantageously, it is also provided that the support frame is designed to accommodate two module housings which are arranged parallel to one another with a small spacing, the support frame being made of electrically insulating material.

Diese Isolierung und der Abstand stellen sicher, daß keine ungewollten Masseschleifen zwischen den beiden Modulgehäusen entstehen. Man kann je nach Bedarf zwei gleiche Modulgehäuse (mit zwei gleichen dritten Steckerhälften) oder zwei verschiedenartige Modulgehäuse einsetzen.This insulation and the distance ensure that there are no unwanted ground loops between the two module housings. Depending on requirements, two identical module housings (with two identical third connector halves) or two different types of module housings can be used.

Dazu ist vorgesehen, daß mehrere bügelartige Ausbildungen und Öffnungen vorgesehen sind, so daß ein Modulgehäuse wahlweise in einer mittleren Position oder in einer von zwei dazu symmetrischen seitlichen Positionen anbringbar ist, oder daß zwei Modulgehäuse jeweils in einer der seitlichen Positionen anbringbar sind. Somit ist die Ausrüstung und Anordnung flexibel.For this purpose, it is provided that several bow-like configurations and openings are provided, so that a module housing can be attached either in a central position or in one of two symmetrical lateral positions, or that two module housings can each be attached in one of the lateral positions. This means that the equipment and arrangement are flexible.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST WAY TO CARRY OUT THE INVENTION

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Zur besseren Verständlichkeit sind verschiedene Details nur vereinfacht oder schematisch dargestellt. Dies gilt insbesondere für die Figuren 1 bis 4, da die hier gezeigten Stecker und Buchsen im Handel erhältlich sind oder damit im wesentlichen übereinstimmen können.The invention is explained in more detail below on the basis of a preferred exemplary embodiment. To make it easier to understand, various details are only shown in simplified or schematic form. This applies in particular to FIGS. 1 to 4, since the plugs and sockets shown here are commercially available or can essentially match them.

Gemäß Fig. 1 ist eine erste Steckerhälfte als Stecker 10 von der Art eines WESTERN-Steckers bekannter Bauart ausgebildet. Er umfaßt ein etwa prismatisches Steckergehäuse 11, in dem mehrere axialparallele Kanäle 12 ausgebildet sind, in die die aufgefächerten isolierten Drahtenden 13 eines Kabels 14 eingesteckt werden. In Querkanälen 15 sind Kontaktlamellen 16 angeordnet, die einerseits mit innenliegenden Schneidenenden 17 die Drahtisolierungen durchstoßen und andererseits im Bereich der stirnseitigen Flachseite 18 des Steckergehäuses 11 die Steckerkontakte 19 (Fig.3) bilden. In der Fig.1 sind der besseren Übersicht wegen nur fünf Kontaktlamellen 16 gezeichnet, doch ist der Standard acht Kontaktlamellen.1, a first connector half is designed as a connector 10 of the type of a Western connector of a known type. It comprises an approximately prismatic connector housing 11 in which a plurality of axially parallel channels 12 are formed, into which the fanned out insulated wire ends 13 of a cable 14 are inserted. Contact blades 16 are arranged in transverse channels 15, on the one hand with internal ones Cutting ends 17 pierce the wire insulation and, on the other hand, form the plug contacts 19 (FIG. 3) in the region of the front flat side 18 of the plug housing 11. For better clarity, only five contact blades 16 are shown in FIG. 1, but the standard is eight contact blades.

Ein wesentlicher Teil des in Steckrichtung hinteren Bereichs des Steckergehäuses 11 ist mit einer Metallabschirmung 21 überdeckt. Der endseitigeTeil der Metallabschirmung 21 ist zu einer Einfassung 22 zusammengebogen und klemmt die dazwischen eintauchende und dort freigelegte Abschirmung 20 des Kabels 14.A substantial part of the rear area of the connector housing 11 in the direction of insertion is covered with a metal shield 21. The end part of the metal shield 21 is bent to form an enclosure 22 and clamps the shield 20 of the cable 14 which is immersed therebetween and exposed there.

Die zweite Steckerhälfte gemäß Fig.2 ist eine Steckbuchse 23, deren Gehäuse zu einem wesentlichen Teil von einer Metallabschirmung 24 eingekapselt ist. Nicht dargestellt sind nach Innen gebogene Lappen der Metallabschirmung 24, die im eingesteckten Zustand des Steckers 10 mit dessen Metallabschirmung 21 kontaktieren. Wenn daher der Stecker 10 in die Steckbuchse 23 eingesteckt wird, kontaktieren die Steckerkontakte 19 im Inneren der Steckbuchse 23 angeordnete Kontaktlamellen 25 und der gesamte Leitungsweg vom Kabel 14 bis zu diesen Kontaktlamellen 25 ist durch eine räumlich eng darum herum reichende Metallabschirmung wirksam geschützt.The second connector half according to FIG. 2 is a socket 23, the housing of which is encapsulated to a substantial extent by a metal shield 24. Not shown are inwardly curved tabs of the metal shield 24, which contact the plug 10 with its metal shield 21 in the inserted state. Therefore, when the plug 10 is inserted into the socket 23, the plug contacts 19 contact inside the socket 23 arranged contact plates 25 and the entire line path from the cable 14 to these contact plates 25 is effectively protected by a spatially closely surrounding metal shield.

Die Steckbuchse 23 ist gemäß Fig.4 auf einer Schaltplatine 26 angeordnet, deren Umriß in der Fig.2 nur strichliert angedeutet ist. Auf der Schaltplatine 26 ist auch eine dritte Steckerhälfte, beispielsweise eine BNC-Buchse 27 von handelsüblicher Art angeordnet. Die erforderliche elektrische Verbindung der Kontaktlamellen 25 mit den jeweils zugehörigen Kontakten der dritten Steckerhälfte wird durch entsprechende Leiterbahnen der Schaltplatine 26 bewirkt. Die Schaltplatine 26 bildet mit der zweiten Steckerhälfte (der Steckbuchse 23) und der dritten Steckerhälfte (der BNC-Buchse 27) einen Steckadapter 28. Verschiedene Steckadapter unterscheiden sich nur hinsichtlich der dritten Steckerhälfte.The socket 23 is arranged according to Figure 4 on a circuit board 26, the outline of which is only indicated by dashed lines in Figure 2. A third plug half, for example a BNC socket 27 of a commercially available type, is also arranged on the circuit board 26. The required electrical Connection of the contact lamellae 25 with the respectively associated contacts of the third connector half is effected by corresponding conductor tracks of the circuit board 26. The circuit board 26 forms a plug adapter 28 with the second plug half (the socket 23) and the third plug half (the BNC socket 27). Different plug adapters differ only with regard to the third plug half.

Dieser Steckadapter 28 ist in einem wenigstens annähernd hohlprismatischen metallischen Modulgehäuse 29 angeordnet, das einen etwa U-förmigen Querschnitt aufweist, mit einer Bodenwand 31, zwei gegenüberliegenden Seitenwänden 32 und zwei gegenüberliegenden Stirnwänden 33, 34. Die Stirnwände 33, 34 haben Öffnungen, durch die die Steckbuchse 23 einerseits und die BNC-Buchse 27 andererseits zugänglich sind. Dabei schließen sich die Ränder der Öffnungen so um die Steckbuchse 23 und den hindurchtretenden Teil der BNC-Buchse 27, daß die Einstrahlung von Störfeldern vermieden wird. Den oberen Abschluß des Modulgehäuses 29 bildet eine metallische Deckplatte 35, die beispielsweise in Führungsnuten 36 der Seitenwände 32 geführt wird. An der Deckplatte 35 sind mehrere wulstartige Erhebungen 37 ausgeprägt, derart, daß sie elastisch mit Vorspannung gegen die Metallabschirmung 24 der Steckbuchse 23 und gegen den Metallkörper der BNC-Buchse 27 drücken. Ähnliche Erhebungen können auch an den Seitenwänden 32 ausgebildet sein. Es ist dadurch sichergestellt, daß zwangsläufig das Modulgehäuse 29 elektrisch mit den Buchsen des Steckadapters 28 verbunden wird.This plug adapter 28 is arranged in an at least approximately hollow-prismatic metallic module housing 29, which has an approximately U-shaped cross section, with a bottom wall 31, two opposite side walls 32 and two opposite end walls 33, 34. The end walls 33, 34 have openings through which the socket 23 on the one hand and the BNC socket 27 on the other hand are accessible. The edges of the openings close around the socket 23 and the part of the BNC socket 27 that passes through in such a way that the radiation of interference fields is avoided. The upper end of the module housing 29 forms a metallic cover plate 35 which is guided, for example, in guide grooves 36 in the side walls 32. A plurality of bead-like elevations 37 are formed on the cover plate 35 in such a way that they press elastically with pretension against the metal shield 24 of the socket 23 and against the metal body of the BNC socket 27. Similar elevations can also be formed on the side walls 32. This ensures that the module housing 29 is inevitably electrically connected to the sockets of the plug adapter 28.

Um die Darstellung übersichtlich zu halten, ist in Fig.2 nur der Umriß des Modulgehäuses 29 strichliert angedeutet. Die Fig.4 zeigt einen relativ großen freien Raum im Modulgehäuse 29 unterhalb der Schaltplatine 26. Dies kommt daher, daß die hier als Beispiel dargestellte BNC-Buchse 27 eine geringe Bauhöhe hat. Die Innenabmessung des Modulgehäuses 29 hingegen ist auf die größte einzusetzende IBM-Datenbuchse abgestimmt. Zwar muß für diese die Öffnung in der Stirnwand 34 erheblich weiter sein, aber diese Anpassung kann durch an Sollbruchkanten ausbrechbare Wandsegmente erreicht werden. da das Modulgehäuse 29 doch etwas aufwendig als Metalldruckguß hergestellt wird, ist es bedeutend kostengünstiger, wenn nur eine Art von Modulgehäuse 29 gefertigt wird.To keep the presentation clear, is only in Fig.2 the outline of the module housing 29 is indicated by dashed lines. 4 shows a relatively large free space in the module housing 29 below the circuit board 26. This is because the BNC socket 27 shown here as an example has a small overall height. The inside dimension of the module housing 29, however, is matched to the largest IBM data socket to be used. The opening in the end wall 34 must be considerably wider for this, but this adaptation can be achieved by wall segments which can be broken out at predetermined breaking edges. since the module housing 29 is produced in a somewhat complex manner as a die-cast metal, it is significantly cheaper if only one type of module housing 29 is manufactured.

Am unteren linken Rand (nach Fig.4) ist ein erster nach rückwärts parallel zu einer Längsachse des Modulgehäuses 29 abstehender Vorsprung 38 angeformt, der nach Art einer Nase von der Stirnwand 33 wegragt. Nicht sichtbar in Fig.4 ist ein weiterer gleichgestalteter Vorsprung, da er in der Ansicht vom Vorsprung 38 verdeckt wird. Die Stirnwand 34 geht über eine niedrige Stufe 39 in die Bodenwand 31 über. Der Zweck ist, daß man hier ein Hebelwerkzeug (eine Messerspitze) ansetzen kann, um das Modulgehäuse 29 aus der Verankerung, die später noch erläutert wird, zu lösen. Im Anschluß an diese Stufe ist ein quer zur Längsachse nach unten ragender zweiter Vorsprung 41 an der Bodenwand 31 angeformt. Der zweite Vorsprung 41 trägt an seinem freien Ende mit Abstand gegenüber der Bodenwand 31 einen etwa parallel zur Längsachse nach vorne (in Richtung zur Stirnwand 34) weisenden Rastnocken 42. Auch zu diesem zweiten Vorsprung 41 gibt es einen formgleichen weiteren, in Fig.4 nicht sichtbaren Vorsprung.At the lower left edge (according to FIG. 4), a first projection 38 protruding rearward parallel to a longitudinal axis of the module housing 29 is formed, which protrudes from the end wall 33 in the manner of a nose. A further projection of the same design is not visible in FIG. 4, since it is covered by the projection 38 in the view. The end wall 34 merges into the bottom wall 31 via a low step 39. The purpose is that a lever tool (a knife tip) can be used here to release the module housing 29 from the anchorage, which will be explained later. Following this step, a second projection 41 projecting downward transversely to the longitudinal axis is formed on the bottom wall 31. The second projection 41 has at its free end at a distance from the bottom wall 31 a locking cam 42 pointing approximately parallel to the longitudinal axis to the front (in the direction of the end wall 34). Also for this second projection 41 there is another of the same shape, not shown in FIG visible lead.

Die Fig.5 und 6 zeigen einen etwa scheibenförmigen Tragrahmen 43 mit einer planen Basis ebene 44, mit der der Tragrahmen auf eine Wand 45 eines Kabelkanals oder eines Gebäudes aufgesetzt wird, so daß er die Wandöffnung 46 überdeckt. Die Wand 45 ist in Fig.6 nur zur Orientierung strichliert angedeutet. Der Umriß des Tragrahmens 43 in der Draufsicht von Fig.5 ist quadratisch mit gerundeten Ecken. Im Mittenbereich hat er eine Öffnung 46, die einen erheblichen Flächenteil einnimmt. Um die Öffnung herum steht ein Wandsockel 48 von der Basisebene 44 senkrecht hoch, der in der Draufsicht etwa U-förmig gestaltet ist. Er dient als Versteifung des Tragrahmens und enthält außerdem an gegenüberliegenden Außenseiten 49 und 51 Rastvertiefungen 52 und 53, deren Zweck später erläutert wird.5 and 6 show an approximately disk-shaped support frame 43 with a flat base plane 44, with which the support frame is placed on a wall 45 of a cable duct or a building, so that it covers the wall opening 46. The wall 45 is indicated by dashed lines in FIG. 6 only for orientation. The outline of the support frame 43 in the plan view of Figure 5 is square with rounded corners. In the middle area it has an opening 46 which occupies a considerable area. Around the opening, a wall base 48 stands vertically high from the base plane 44, which is approximately U-shaped in plan view. It serves as a stiffening of the support frame and also contains locking recesses 52 and 53 on opposite outer sides 49 and 51, the purpose of which will be explained later.

Zwischen den Enden der U-Schenkel des Wandsockels 48 erstreckt sich eine Auflagefläche 54, die etwa von der rechten Randkante bis ungefähr zur Mitte des Tragrahmens 43 reicht. In der Querrichtung nimmt sie fast die ganze Breite des Tragrahmens ein. Die Oberseite der Auflagefläche 54 ist im gezeichneten Beispiel nach Fig.6 in einem Neigungswinkel von etwa 12 Grad gegenüber der Basisebene 44 ausgerichtet. Es versteht sich, daß Neigungswinkel zwischen 10 und 20 Grad ausgeführt werden können. An der Innenkante der Auflagefläche 54 ist eine zu dieser senkrecht hochstehende Leiste 56 angeformt. Sie hat vier längs in gleichen Abständen verteilte Ausnehmungen 57, 58, 59, 61, in die die ersten Vorsprünge 38 eines Modulgehäuses 29 eingreifen können. Die Schnittdarstellung nach Fig.6 folgt in-soweit nicht korrekt dem Verlauf der Schnittebene in Fig.5, weil danach die Öffnung 57 nicht aufgeschnitten wäre. Zufolge der vorgenannten Öffnungen erhalt der Steg 56 eine bügelartige Ausbildung. Nahe der Randkante 55 sind in der Auflagefläche 54 vier Öffnungen 62, 63, 64, 65 gleichfalls in gleichen Abständen verteilt ausgebildet. In sie können die vorgenannten zweiten Vorsprünge 41 eintauchen und mit deren Rastnocken unter der Auflagefläche einrasten. Da der Tragrahmen 43 aus Kunststoff besteht, kann dabei die Randzone vor den metallischen Rastnocken 42 elastisch ausweichen beim Ein- bzw. Ausrasten eines Modulgehäuses. In den Figuren 5 und 6 ist ein Modulgehäuse 29 in einer der drei möglichen Rastpositionen dargestellt. Wegen des gleichen Abstands zwischen den Ausnehmungen 57 - 61 und Öffnungen 62 - 65 kann das Modulgehäuse gleichermaßen mittig, wie in der anderen Randlage eingesetzt werden. Es können auch zwei Modulgehäuse in den beiden Randpositionen angeordnet werden. Das Ausrasten eines Modulgehäuses erfolgt mit Unterstützung etwa einer Messerspitze, die zwischen der Stufe 39 und der Auflagefläche 54 als Hebel eingesetzt werden kann.A support surface 54 extends between the ends of the U-legs of the wall base 48 and extends approximately from the right edge to approximately the center of the support frame 43. In the transverse direction it takes up almost the entire width of the support frame. In the example shown in FIG. 6, the top of the support surface 54 is oriented at an inclination angle of approximately 12 degrees with respect to the base plane 44. It is understood that angles of inclination between 10 and 20 degrees can be carried out. On the inner edge of the support surface 54, a bar 56 which is perpendicular to this is formed. It has four recesses 57, 58, 59, 61, which are distributed along the same spacing and into which the first projections 38 of a module housing 29 can engage. The sectional view according to FIG. 6 does not follow the course of the sectional plane in FIG. 5 insofar as the opening 57 would then not have been cut open. As a result of the aforementioned openings, the web 56 receives one bow-like training. Near the edge 55, four openings 62, 63, 64, 65 are also formed in the bearing surface 54 distributed at equal intervals. The aforementioned second projections 41 can dip into them and engage with their locking cams under the bearing surface. Since the support frame 43 is made of plastic, the edge zone in front of the metallic locking cams 42 can yield elastically when a module housing is engaged or disengaged. FIGS. 5 and 6 show a module housing 29 in one of the three possible latching positions. Because of the same distance between the recesses 57-61 and openings 62-65, the module housing can be used in the center, as in the other edge position. Two module housings can also be arranged in the two edge positions. A module housing is disengaged with the support of, for example, a knife tip, which can be used as a lever between the step 39 and the support surface 54.

In den Fig. 7 und 8 ist ein rahmenartiger Gehäuseteil 66 dargestellt, der über den Tragrahmen 43 gestülpt wird. Der Gehäuseteil 66 hat vier jeweils von der Basisebene 44 senkrecht hochstehende Rahmenwände 67, 68, 69, 71, die gleich hoch sind (beispielsweise 2,5 cm).Von den gegenüberliegenden Innenseiten der Rahmenwände 67 und 69 stehen Stegansätze 72 und 73 ab, deren Innenkanten 74, 75 in die aus Fig.5 ersichtlichen Rastvertiefungen 52, 53 jeweils einrasten, wodurch der Gehäuseteil 66 in seiner Lage auf dem Tragrahmen 43 fixiert wird.7 and 8, a frame-like housing part 66 is shown, which is put over the support frame 43. The housing part 66 has four frame walls 67, 68, 69, 71 which are vertically upright from the base plane 44 and which are of the same height (for example 2.5 cm). Web projections 72 and 73 protrude from the opposite inner sides of the frame walls 67 and 69 Snap inner edges 74, 75 into the locking recesses 52, 53 shown in FIG. 5, whereby the housing part 66 is fixed in its position on the support frame 43.

In Fig.8 ist ein den Gehäuseteil 66 ergänzender und abschließender Deckelteil 76 strichliert angedeutet. Er hat eine Deckfläche 77, zwei gegenüberliegende, etwa dreieckförmige Seitenflächen 78, eine Vorderfläche 79 und eine rudimentäre Rückfläche 81 in Gestalt eines Zylindermantelabschnitts, der koaxial zu einer Schwenkachse verläuft, um die der Deckelteil 76 gegenüber dem Gehäuseteil verschwenkbar gelagert ist. Dazu ragen vom Gehäuseteil zwei Bügel 82, 83 hoch, die aufeinander zu gerichtete Zapfen 84, 85 aufweisen. Diese greifen in entsprechende Löcher in nicht besonders dargestellten Streben im Eckbereich von Deckfläche 76 und Rückfläche 81 ein. An der Innenseite der Rahmenwand 71 ist noch ein Federbügel 86 angeformt, der gegen eine ebenfalls nicht besonders dargestellte Nocke im Eckbereich der Rückfläche 81 drückt und bewirkt, daß der Deckelteil in die Schließlage vorgespannt wird.A cover part 76 which complements and concludes the housing part 66 is indicated by dashed lines in FIG. He has one Cover surface 77, two opposite, approximately triangular side surfaces 78, a front surface 79 and a rudimentary rear surface 81 in the form of a cylinder jacket section, which runs coaxially to a pivot axis about which the cover part 76 is pivotally mounted relative to the housing part. For this purpose, two brackets 82, 83 protrude from the housing part, which have pins 84, 85 directed towards one another. These engage in corresponding holes in struts (not shown) in the corner area of the top surface 76 and rear surface 81. On the inside of the frame wall 71, a spring clip 86 is also formed, which presses against a cam in the corner region of the rear surface 81, which is also not particularly shown, and causes the cover part to be prestressed into the closed position.

Die Fig.8 veranschaulicht, daß durch die Schräglage des Modulgehäuses 29 erreicht wird, daß das Kabel 14 einen mäßig gekrümmten Verlauf erhält. Dies reduziert mechanische Spannungen, die vom Kabel auf den Stecker 10 ausgeübt werden. In der rechteckigen Vorderfläche 79 des Deckelteiles 76 ist ein erster randoffener Ausschnitt 87 angedeutet, durch den auch bei geschlossenem Deckelteil die BNC-Buchse 27 zugänglich ist. Im Zusammenhang mit einer IBM-Datenbuchse ist es erforderlich, auch in der Rahmenwand 68 einen zweiten randoffenen Ausschnitt freizumachen. Dies kann vorteilhafterweise durch ein entlang von Sollbruchlinien ausbrechbares Wandstück realisiert werden. Die beiden Ausschnitte ergänzen sich dann zu einem insgesamt rechteckigen oder länglich ovalen Gesamtausschnitt.8 illustrates that the inclined position of the module housing 29 means that the cable 14 is given a moderately curved course. This reduces mechanical stresses exerted by the cable on the connector 10. In the rectangular front surface 79 of the cover part 76, a first cutout 87 open to the edge is indicated, through which the BNC socket 27 is accessible even when the cover part is closed. In connection with an IBM data socket, it is also necessary to make a second cutout open in the frame wall 68. This can advantageously be achieved by a wall piece that can be broken out along predetermined breaking lines. The two sections then complement each other to form an overall rectangular or elongated oval section.
