Abstract

A data bus connection (11) for data processing installations has a screened, coaxial connector, preferably one having two internal conductors (25, 50), in the case of which a contact is operated when the plug is connected, which contact short-circuits the two inner conductors (25, 50) to one another when the connection is decoupled. In the case of the embodiment, a resistor can also be connected between the internal conductors (25, 50) and the screen (15). In this way, when an apparatus is uncoupled, the data cable is either provided with a terminating resistor or is looped through. <IMAGE>

Description

Die Erfindung betrifft eine Anschlußeinrichtung für Datenübertragungsleitungen, insbesondere für ein Datennetz, mit wenigstens einer Steckvorrichtung mit Steckkontakten, bei der eine Buchse und ein Stecker zusammenwirken.The invention relates to a connection device for data transmission lines, in particular for a data network, with at least one plug device with plug contacts, in which a socket and a plug interact.

In Datenübertragungsleitungen, zu denen sowohl Vernetzungen von Datenverarbeitungsanlagen als auch andere Übertragungsleitungen von meist hochfrequenten Signalen, wie Video-Signalen etc., gehören, werden meist hochfrequente Signale übertragen, an deren Übermittlungsgenauigkeit hohe Ansprüche gestellt werden, weil schon geringfügige Störungen erhebliche Folgen haben können. Die Leitungen sind dabei meist Koaxialkabel mit Abschirmung. Bei Datennetzen sind oftmals die Anschlußwiderstandsverhältnisse sehr kritisch, und eine Abzweigung von einem durchgehenden Leitungsstrang ist meist nicht ohne besondere Maßnahmen möglich. Ein Datennetz muß meist von einer Anlage zur anderen durchgeschleift werden, d.h. eine Leitung muß zu einem Gerät hin und von diesem zum nächsten Gerät weiterlaufen.In data transmission lines, which include networks of data processing systems as well as other transmission lines of mostly high-frequency signals, such as video signals, etc., high-frequency signals are usually transmitted, the transmission accuracy of which is subject to high demands because even minor interference can have serious consequences. The cables are mostly coaxial cables with shielding. In the case of data networks, the connection resistance ratios are often very critical, and it is usually not possible to branch off from a continuous cable run without special measures. A data network usually has to be looped through from one system to another, i.e. a line must run to one device and from there to the next device.

Aus dem DE-U-89 08 236 ist eine Anschlußeinrichtung bekanntgeworden, bei der eine übliche Telefondose als Durchschalt-Abzweigdose verwendet wird. Sie enthält in der Dose Kontakte, die normalerweise aneinander anliegen und beim Einstecken des Steckers gleichzeitig voneinander getrennt und mit den entsprechenden Kontakten des Steckers verbunden werden. Von dort aus läuft ein doppeltes, entsprechend abgeschirmtes Kabel zu einer Koaxial-Steckvorrichtung in Form eines BNC-Steckers, der mit einer entsprechenden BNC-Einbaubuchse des angeschlossenen Gerätes verbunden werden kann. Auch die Anschlußdose selbst ist über BNC-Steckverbindungen mit dem Datenbus verbunden.From DE-U-89 08 236 a connection device has become known in which a conventional telephone socket is used as a through-junction box. It contains contacts in the socket, which normally abut one another and are simultaneously separated from each other when the plug is inserted and connected to the corresponding contacts on the plug. From there, a double, appropriately shielded cable runs to a coaxial connector in the form of a BNC connector, which can be connected to a corresponding BNC socket of the connected device. The junction box itself is also connected to the data bus via BNC connectors.

Diese Anschlußeinrichtung sorgt dafür, daß der beim Einstecken eines Kabels für ein angeschlossenes Gerät getrennte und über das Gerät geleitete Datenbus beim Herausziehen des Steckers wieder geschlossen und weitergeleitet wird. Die als Flachsteckverbindungen ausgebildeten Anschlußkontakte sind jedoch für Datenleitungen nicht ausreichend zuverlässig kontaktiert, und es liegt keine vollständige Abschirmung vor. Das ist besonders kritisch, weil derartige Anschlußdosen meist an Kabelkanälen verlegt werden, die auch Netzleitungen führen, so daß die Anfälligkeit gegen Störsignale besonders groß ist.This connection device ensures that the data bus, which is disconnected when a cable is plugged in for a connected device and is passed through the device, is closed and forwarded again when the plug is pulled out. However, the connection contacts designed as flat plug connections are not sufficiently reliably contacted for data lines, and there is no complete shielding. This is particularly critical because such sockets are usually laid on cable ducts that also carry power lines, so that the susceptibility to interference signals is particularly high.

Die DE-A-27 07 250, die dem Oberbegrift entspricht, zeigt eine Steckverbindung mit einem integrierten Schalter, der von der Mittelbuchse des Koaxialsteckers betätigt wird. Diese ist abgefedert axial beweglich und hebt dabei einen Ring von einem Ringkontakt ab. Die Buchse ist im nicht an einen Stecker angeschlossenen Zustand kurzgeschlossen.DE-A-27 07 250, which corresponds to the general term, shows a plug connection with an integrated switch which is actuated by the center socket of the coaxial plug. This is sprung axially movable and lifts a ring from a ring contact. The socket is short-circuited when not connected to a plug.

Die US-A 3 873 785 zeigt eine Koaxial-Steckvorrichtung, bei der an einen durch Axialbewegung betätigten Schalter in Form einer Kontaktfeder ein Abschlußwiderstand angeschlossen und dadurch einschaltbar ist.US-A 3 873 785 shows a coaxial plug-in device in which a terminating resistor is connected to a switch actuated by axial movement in the form of a contact spring and can thus be switched on.

Die Erfindung bezweckt, eine Anschlußeinrichtung für Datenübertragungsleitungen zu schaffen, die aufgrund eines anderen Lösungsprinzips sehr zuverlässig und störungssicher arbeitet und bei geringer Baugröße optimal an das Netz und die Anschlußgeräte anpaßbar ist.The invention aims to provide a connection device for data transmission lines that works very reliably and fail-safe due to another solution principle and is optimally adaptable to the network and the connection devices with a small size.

Zur Lösung dieser Aufgabe wird vorgeschlagen, daß die nach Art einer BNC-Koaxial-Steckverbindung mit einem Innenkontakt und einem demgegenüber isolierten Abschirmungs-Außenkontakt ausgebildete Steckverbindung einen den Innenkontakt umgebenden, durch eine Isolierung davon getrennten Zwischenkontakt aufweisen. Eine damit insgesamt dreipolige Koaxialsteckverbindung macht keinen wesentlichen Herstellungsmehraufwand und ermöglicht den Anschluß insbesondere von Anschlüssen an Datennetzen, ist jedoch auch für andere Verwendungszwecke, beispielsweise für Stereoanschlüsse, getrennte Video- und Audio- oder andere Anschlüsse mit zwei abgeschirmten Leitern, brauchbar.To solve this problem, it is proposed that the type of BNC coaxial plug-in connection with an internal contact and a shield-external contact insulated from it have an intermediate contact surrounding the internal contact and separated from it by insulation. A total of three-pole coaxial connector thus makes no significant additional production costs and enables the connection of connections to data networks in particular, but is also useful for other purposes, for example for stereo connections, separate video and audio or other connections with two shielded conductors.

Bei einer bevorzugten Ausführungsform kann einer der Steckkontakte beim Zusammenstecken der Steckvorrichtung in dieser axial beweglich angeordnet und mit einem bei Axialbewegung betätigten Schaltkontakt versehen sein. Damit kann die Auftrennung des beispielsweise an einer Wand entlanggeführten Datenbusses beim Einstecken eines Anschlußsteckers bewerkstelligt werden, und beim Lösen dieses Steckers schließt sich die Leitung wieder und kann somit die weiteren Geräte versorgen. Das ist in einer koaxialen Steckverbindung, vorzugsweise mit Verriegelung in Axialrichtung durch Schraub- oder Bajonettverschluß, möglich, die ideal, nämlich vollständig, abgeschirmt ist.In a preferred embodiment, one of the plug contacts can be arranged in an axially movable manner when the plug device is plugged together and can be provided with a switching contact actuated during axial movement. This enables the disconnection of the data bus, which is carried along a wall, for example, when a connector is inserted, and when this connector is disconnected, the line closes again and can thus supply the further devices. This is possible in a coaxial plug connection, preferably with locking in the axial direction by means of a screw or bayonet lock, which is ideally, namely completely, shielded.

Nach einem weiteren Merkmal der Erfindung kann in der Steckvorrichtung ein beim Trennen der Steckverbindung automatisch eingeschalteter Abschlußwiderstand vorgesehen sein. Dieser kann auf gleiche Weise durch eine axial verschiebliche zentrale Hülse geschaltet werden, ohne irgendwelchen zusätzlichen Raum einzunehmen.According to a further feature of the invention, a terminating resistor which is automatically switched on when the plug connection is disconnected can be provided in the plug device his. This can be switched in the same way through an axially displaceable central sleeve without taking up any additional space.

Eine besonders bevorzugte Ausführungsform verbindet eine solche 2-Innenleiter-Steckverbindung mit zwei üblichen Steckverbindungen, beispielsweise BNC-Steckverbindungen, in T-Form zu einer Anschlußeinheit, bei der über übliche BNC-Verbindungen der Datenbus beidseitig angeschlossen wird und die Anschlußleitungen mit automatischer Durchschaltung anschließbar sind. Mehrere dieser T-Stücke können unmittelbar durch Stecken miteinander verbunden und zu ganzen Steckerleisten zusammengefaßt werden.A particularly preferred embodiment connects such a 2-conductor plug connection with two conventional plug connections, for example BNC plug connections, in a T-shape to form a connection unit in which the data bus is connected on both sides via conventional BNC connections and the connecting lines can be connected with automatic switching . Several of these T-pieces can be directly connected to each other by plugging in and combined to form complete plug strips.

Die vorher beschriebenen Merkmale sind, obwohl auch einzeln anwendbar, besonders vorteilhaft in Kombination miteinander.The features described above, although also applicable individually, are particularly advantageous in combination with one another.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei auch diese Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte Ausführungen darstellen können.

The upper end of the spring 28 in the drawing is guided through a central pin 31 of the line pin 51 penetrating the flange 30. The ring 26, flange 30 and the compression spring 28 lie in a space 33 of an insulating body 34 which is designed in the manner of a blind bore and which is fastened to a metallic outer body 36 by means of an overlapping fastening sleeve 35.

Die Innenkontakthülse 14 ist von einem Isolierrohr 48 umgeben, das wiederum von einem hülsen- bzw. rohrförmigen Zwischenkontakt 50 umgeben ist. Über den Isolierkörper 24, den diese Einheit durchdringt, ragt sie vor, daß sie die Innenhülse bis nahe an ihr anschlußseitiges Ende heran umgibt. Die Zwischenkontakt-Hülse 50 hat an ihrem anschlußfernen Ende einen Flansch 52, der in einer entsprechenden Vertiefung des Isolierkörpers 24 liegt und über eine Leitung 53 an den Innenleiter-Stift 54 eines üblichen BNC-Steckers, der hier jedoch ohne Verriegelungs-Bajonett-Hülse ausgebildet ist. Mit einer dieser gegenüberliegenden BNC-Buchse 56 mit einer Innenleiter-Hülse 57, die an den Innenleiter-Anschluß 51a der Buchse 12 angeschlossen ist, bilden die BNC-Steckvorrichtungen 54, 56 und die Buchse 12 eine insgesamt T-förmige Einheit 70. Die beiden BNC-Verbinder 55, 56 sind dabei in eine Querbohrung eines rohrförmigen, an seinem freien Ende abgeschlossenen Metallgehäuseteils 35 eingesetzt. Es ergibt sich somit eine sehr kompakte Einheit, deren Anwendungsmöglichkeiten noch anhand der Figuren 4 bis 6 näher beschrieben wird.The inner contact sleeve 14 is surrounded by an insulating tube 48, which in turn is surrounded by a sleeve or tubular intermediate contact 50. Over the insulating body 24, which this unit penetrates, it projects that it surrounds the inner sleeve up to close to its end on the connection side. The intermediate contact sleeve 50 is on its distal end a flange 52, which lies in a corresponding recess of the insulating body 24 and via a line 53 to the inner conductor pin 54 of a conventional BNC connector, but which is designed here without a locking bayonet sleeve. With one of these opposite BNC socket 56 with an inner conductor sleeve 57, which is connected to the inner conductor connection 51a of the socket 12, the BNC plug devices 54, 56 and the socket 12 form an overall T-shaped unit 70. The two BNC connectors 55, 56 are inserted into a transverse bore of a tubular metal housing part 35 which is closed at its free end. The result is a very compact unit, the possible uses of which are described in more detail with reference to FIGS. 4 to 6.

Der axialbewegliche Zentralstift 25, der an seinem Ende die geschlitzte und im nicht angeschlossenen Zustand etwas verjüngt zusammengedrückte Innenkontakthülse 14 aufweist, liegt mit der Kontaktschulter 42 seines Ringes 26 im entkuppelten Zustand (Fig. 1) auf dem Flansch 52 auf und verbindet somit die Innenanschlüsse 54, 57 der BNC-Verbinder 55, 56 elektrisch miteinander. Beim Aufsetzen eines Steckers 13 nach Fig. 2 wird durch dessen Innenleiter-Stift 23, die Innenkontakthülse 14 und der Zentralstift 25 entgegen der Kraft der Feder 28 axial verschoben, und der Schaltkontakt 10 über die Kontaktschulter 42 wird geöffnet, so daß nunmehr der Innenleiter 14, 23 nur an die Innenhülse 57 der Buchse 56 angeschlossen ist, während der Zwischenkontakt 50 an den Innenleiterstift 54 des Steckers 55 angeschlossen ist.The axially movable central pin 25, which has at its end the slotted inner contact sleeve 14 which is slightly tapered in the non-connected state, lies with the contact shoulder 42 of its ring 26 in the uncoupled state (FIG. 1) on the flange 52 and thus connects the inner connections 54 , 57 of the BNC connectors 55, 56 electrically to one another. 2, the inner conductor pin 23, the inner contact sleeve 14 and the central pin 25 move axially against the force of the spring 28, and the switch contact 10 is opened via the contact shoulder 42, so that the inner conductor 14th , 23 is only connected to the inner sleeve 57 of the socket 56, while the intermediate contact 50 is connected to the inner conductor pin 54 of the plug 55.

Gemäß Fig. 3 kann der Isoliereinsatz 24 eine seitliche, axialgerichtete Ausnehmung 39 haben, in der ein elektrischer Widerstand 40 nach Art eines Subminiaturwiderstandes aufgenommen ist. Er ist so zwischen dem Außenkörper 35, dem hülsenförmigen Abschirm-Außenkontakt 15 und dem Isolierkörper 34 festgelegt, daß er den Abschirm-Außenkontakt mit der einen Stirnfläche elektrisch kontaktiert, während die andere kontaktfähige Stirnfläche 41 zum Teil zur Festlegung von dem Isolierkörper 35 übergriffen wird, während sich auf dem anderen Stirnflächenteil die eine Abstützschulter 42 bildende, in der Zeichnung untere Ringfläche des Ringes 26 kontaktierend abstützt. Es bildet sich also ein Schaltkontakt 10.According to FIG. 3, the insulating insert 24 can have a lateral, axially directed recess 39, in which an electrical resistor 40 is received in the manner of a subminiature resistor. It is fixed between the outer body 35, the sleeve-shaped shielding external contact 15 and the insulating body 34 in such a way that it makes electrical contact with the shielding external contact with one end face, while the other contactable end face 41 is overlapped in part by the insulating body 35 for fixing purposes. while on the other end face part which forms a support shoulder 42, in the drawing the lower annular surface of the ring 26 is supported in contact. A switching contact 10 is thus formed.

Der in Fig. 2 gezeigte Stecker 13 enthält seinen als Zentralstift ausgebildeten Innenkontakt 23 in der Ausnehmung eines Isolierkörpers 43, an dessen Außenseite eine Abschirmungs-Außenkontakthülse 44 verläuft, die längsgeschlitzt ist, so daß sich einzelne Kontaktfahnen oder Zungen bilden, die an der oberen, freien Seite äußere Verdickungen 45 haben.The plug 13 shown in FIG. 2 contains its internal contact 23 designed as a central pin in the recess of an insulating body 43, on the outside of which a shielding external contact sleeve 44 runs, which is slit lengthwise, so that individual contact tabs or tongues form on the upper, free side have outer thickenings 45.

Der in Fig. 2 dargestellte Stecker 13 enthält eine geschlitzte und damit federnd nachgiebige Innenkontakthülse 60, die im Inneren des hier rohrförmig ausgeführten Isolierkörpers 43 angeordnet ist und nach innen gegenüber dem Innenkontakt 23 einerseits durch einen Luftraum und andererseits durch einen Isoliereinsatz 61 isoliert ist. Beim Zusammenstecken wirkt diese Zwischenkontakthülse 60 mit dem Zwischenkontakt 50 zusammen, so daß sich eine Steckverbindung ergibt, bei der drei Kontaktebenen koaxial zueinander liegen. Durch Schlitzung und Einwärtsspreizung der Zwischenkontakthülse 60 ist ein ausreichender Kontaktdruck möglich. Innenleiter 23 und Zwischenkontakt 26 sind mit getrennten Anschlußfahnen 62, 63 verbunden, die im vorliegenden Fall im Innenraum eines quer zur Steckrichtung (Achse 64) verlaufenden Anschlußstückes 65 liegen, in das ein Koaxialkabel durch eine Anschlußöffnung 66 eingeführt wird. Es wird damit ein sehr raumsparender und stabiler Winkelstecker gebildet.The plug 13 shown in Fig. 2 contains a slotted and thus resilient inner contact sleeve 60, which is arranged inside the tubular insulating body 43 and is insulated from the inside contact 23 on the one hand by an air space and on the other hand by an insulating insert 61. When plugging together, this intermediate contact sleeve 60 cooperates with the intermediate contact 50, so that there is a plug connection in the three contact levels are coaxial to each other. A sufficient contact pressure is possible by slitting and expanding the intermediate contact sleeve 60 inwards. Inner conductor 23 and intermediate contact 26 are connected to separate connecting lugs 62, 63, which in the present case lie in the interior of a connecting piece 65 running transversely to the plugging direction (axis 64), into which a coaxial cable is inserted through a connecting opening 66. A very space-saving and stable angled plug is thus formed.

Wenn bei der Ausführung nach Fig. 3 die Buchse beispielsweise an einem Datenverarbeitungsgerät zu dessen Anschluß an ein Leitungsnetz oder an einer entsprechenden Anschlußbuchse vorgesehen ist, so stellt der Schaltkontakt 10 im entkuppelten Zustand über den Widerstand 40 eine elektrische Verbindung zwischen dem Innenkontakt 25 und dem metallischen Gehäuse der Buchse, und damit auch der Masse des Gerätegehäuses und der Abschirmung, hergestellt. Dies erspart das besondere Anbringen eines mit dem entsprechenden Anschlußwiderstand (Fig. 3) oder einer Kurzschlußeinrichtung vorgesehenen Abschlußsteckers, wenn ein Anschlußkabel entfernt wird. Insbesondere bei Geräten mit mehreren Anschlußbuchsen ist dies notwendig, um die Datenverarbeitung nicht zu stören.If, in the embodiment according to FIG. 3, the socket is provided, for example, on a data processing device for its connection to a line network or to a corresponding connection socket, the switch contact 10 in the uncoupled state provides an electrical connection between the inner contact 25 and the metallic one via the resistor 40 Housing of the socket, and thus also the mass of the device housing and the shield. This saves the special attachment of a terminating plug provided with the corresponding connecting resistor (FIG. 3) or a short-circuit device when a connecting cable is removed. This is necessary in particular in the case of devices with several connection sockets, in order not to interfere with the data processing.

Wenn jedoch mittels des Steckers 13 (Fig. 2) ein Verbindungskabel angeschlossen wird, dann kommt die geschlitzte Innenkontakthülse 14 mit dem Innenkontakt 23 des Steckers in Kontakt, und die Abschirmungs-Außenkontakthülse 45 legt sich an die Innenfläche der entsprechenden Abschirmungs-Außenkontakthülse 15 der Buchse 11 an. Da die Außenkontakthülse 14 weiter in den Raum 47 innerhalb der Abschirmungs-Außenkontakthülse 15 hineinragt, als dies dem gekuppelten Zustand entspricht, wird bei der Einkupplung die Innenkontakthülse 14 zusammen mit dem Zentralstift 25 in Achsrichtung gegen die Kraft der Feder 28 verschoben, so daß die Abstützschulter 42 des Ringes 26 von der Stirnfläche 41 des Widerstandes 40 (Fig. 3) oder des Flansches 52 abhebt und damit der elektrische Kontakt zwischen dem Innenleiter 14, 25, 31 und dem Außengehäuse 15, 35, 36 elektrisch unterbrochen ist. Die Druckfeder 28 stellt dabei auch die elektrische Leitungsverbindung zwischen dem Zentralstift 25 und dem Anschlußstift 51 her.However, if a connecting cable is connected by means of the plug 13 (FIG. 2), then the slotted inner contact sleeve 14 comes into contact with the inner contact 23 of the plug, and the shielding outer contact sleeve 45 rests against the inner surface of the corresponding shielding outer contact sleeve 15 of the socket 11. Since the outer contact sleeve 14 protrudes further into the space 47 within the shielding outer contact sleeve 15 than this corresponds to the coupled state, the inner contact sleeve 14 together with the central pin 25 is displaced in the axial direction against the force of the spring 28 during coupling, so that the support shoulder 42 of the ring 26 lifts off the end face 41 of the resistor 40 (FIG. 3) or the flange 52 and thus the electrical contact between the inner conductor 14, 25, 31 and the outer housing 15, 35, 36 is electrically interrupted. The compression spring 28 also establishes the electrical line connection between the central pin 25 and the connecting pin 51.

Gemäß Fig. 3 wird automatisch ein Abschlußwiderstand ein- und ausgeschaltet. Der Widerstand und seine Schalteinrichtung sind in einem Gehäuse von der Größe einer normalen BNC-Buchse untergebracht. Der Axialhub des Zentralstifts 25 kann wesentlich geringer sein als dargestellt. Durch die Verriegelung mittels des Bajonetts, das durch Drehung der Drehhülse 19 verriegelt wird, ist diese axiale Lage auch dauerhaft festgelegt. Hier könnte auch eine entsprechende Schraubverbindung durch Überwurfmutter oder dgl. vorgesehen sein.3, a terminating resistor is automatically switched on and off. The resistor and its switching device are housed in a housing the size of a normal BNC socket. The axial stroke of the central pin 25 can be significantly less than shown. By locking by means of the bayonet, which is locked by rotating the rotating sleeve 19, this axial position is also permanently fixed. A corresponding screw connection by means of a union nut or the like could also be provided here.

Fig. 4 und 5 zeigen eine Wandanschlußdose, die mit zwei Anschlußeinheiten 70 entsprechend Fig. 1 versehen sind. Dabei ist zu erkennen, daß die beiden T-förmigen Einheiten 70 jeweils mit einem BNC-Stecker 55 und 56 unmittelbar zusammengesteckt sind, so daß sie die Grundform des griechischen Buchstabens Pi haben. Zwei Buchsen 12 ragen also nebeneinander aus einer Frontplatte 71 der Wanddose 72 heraus. Der Außenkörper 36 hält zwischen seinem mit Schlüsselflächen versehenen flanschartigen Bund und einer auf sein Außengewinde geschraubten Ringmutter 38 eine isolierende Verbindungsbrücke oder -platte 73, die die zusammengesteckten Einheiten 70 so aneinander festlegen, daß die beiden Buchsen 12 parallel zueinander verlaufen. Die Verbindungsplatte 73 dient ferner zur Halterung eines Randbefestigungsteils 74, das in eine übliche Wand-Verteilerdose eingesetzt werden kann.4 and 5 show a wall junction box, which are provided with two connection units 70 corresponding to FIG. 1. It can be seen that the two T-shaped units 70 each with a BNC connector 55 and 56 immediately are put together so that they have the basic shape of the Greek letter pi. Two sockets 12 protrude side by side from a front plate 71 of the wall socket 72. The outer body 36 holds between its flanged flange-like collar and a ring nut 38 screwed onto its external thread an insulating connecting bridge or plate 73 which fix the assembled units 70 to one another in such a way that the two bushings 12 run parallel to one another. The connecting plate 73 also serves to hold an edge fastening part 74 which can be used in a conventional wall junction box.

Es ist zu erkennen, daß durch die T-förmige Ausbildung der Einheit 70 beliebig viele Anschlußbuchsen 12 nebeneinander angeordnet werden können, wobei diese parallel zueinander, jedoch auch unter beliebigen Winkeln angeordnet sein können. So könnte beispielsweise eine Anschlußleiste Anschlußdosen an mehreren Seiten aufweisen, indem die Buchsen 12 jeweils unter einem Winkel von beispielsweise 90 oder 180° gegenüber der benachbarten Buchse versetzt angeordnet werden. In jedem Falle bleibt erhalten, daß eine durchgehende Datenübertragungsleitung (Datenbus) an den jeweiligen beiden Außenanschlüssen 55, 56 angeschlossen werden kann und sie im Inneren der gesamten Einheit vollständig abgeschirmt verläuft, wobei eine automatische Durchschaltung, d.h. Überbrückung des jeweiligen Anschlusses 12 erfolgt, wenn dieser nicht mit einem entsprechenden Anschlußstecker 13 (Fig. 7) belegt ist. Durch die Verriegelung mittels des Bajonett-Verschlusses 17 sind die sehr kompakten und stabilen Anschlußverbindungen auch gegen versehentliches Lösen gesichert, was bei der Datenübertragung besonders wichtig ist.It can be seen that as a result of the T-shaped design of the unit 70, any number of connection sockets 12 can be arranged next to one another, whereby these can be arranged parallel to one another, but also at any angle. For example, a terminal block could have sockets on several sides, in that the sockets 12 are each offset at an angle of, for example, 90 or 180 ° from the adjacent socket. In any case, it is retained that a continuous data transmission line (data bus) can be connected to the respective two external connections 55, 56 and that it runs completely shielded inside the entire unit, with an automatic switching through, that is, bridging of the respective connection 12, if this takes place is not assigned a corresponding connector 13 (Fig. 7). By locking by means of the bayonet lock 17, the very compact and stable connection connections also secured against accidental loosening, which is particularly important when transferring data.

Zum angeschlossenen Gerät führt von der jeweiligen Anschlußbuchse 12 ein Anschlußkabel 75, das aus einem Stecker 13 gemäß Fig. 4, einer abgeschirmten Anschlußleitung 76 mit zwei Innenleitern 77, 78 und einem normalen BNC-Stecker 13 nach Fig. 2 besteht. Dabei sind die beiden Innenleiter zwar getrennt voneinander an die Anschlußfahnen 62, 63 des Steckers 13 angeschlossen, werden jedoch im BNC-Stecker 13 zusammen an dessen mittleren Anschlußstift 23 angeschlossen. Es hat sich gezeigt, daß diese getrennte Führung bis kurz vor das verarbeitende Gerät zum Zwecke der Anpassung wichtig ist. Die Abschirmung 79 der Anschlußleitung ist durch eine Crimpoder Preßhülse 80 am Steckergehäuse befestigt.A connecting cable 75 leads to the connected device from the respective connecting socket 12, which consists of a plug 13 according to FIG. 4, a shielded connecting line 76 with two inner conductors 77, 78 and a normal BNC plug 13 according to FIG. 2. The two inner conductors are connected separately from one another to the connecting lugs 62, 63 of the plug 13, but are connected together in the BNC plug 13 to its central connecting pin 23. It has been shown that this separate guidance is important until shortly before the processing device for the purpose of adaptation. The shield 79 of the connecting line is fastened to the plug housing by a crimping or compression sleeve 80.

Es ist noch zu bemerken, daß die neuartigen Steckverbindungen 12, 13 mit Koaxial-Zwischenkontakten 50, 60 teilweise mit normalen BNC-Steckern kompatibel sind. So kann beispielsweise ein BNC-Stecker 13 auch an eine Buchse 12 angeschlossen werden, wobei der Zwischenkontakt 50 dann unbelegt bleibt. Es ist ferner auch möglich, die Buchse 12 ohne den internen Schaltkontakt 10 auszuführen, wenn dies im speziellen Anwendungsfall nicht notwendig ist. Auch in der Anschlußdose oder den Anschlußkabeln könnte eine Ausführung mit Abschlußwiderstand entsprechend Fig. 3 angewendet werden, obwohl dies bei der Durchschalt-Anschlußdose 72 an sich nicht nötig ist.It should also be noted that the novel plug connections 12, 13 with coaxial intermediate contacts 50, 60 are partially compatible with normal BNC plugs. For example, a BNC plug 13 can also be connected to a socket 12, the intermediate contact 50 then remaining unoccupied. It is also possible to design the socket 12 without the internal switch contact 10 if this is not necessary in the special application. An embodiment with a terminating resistor according to FIG. 3 could also be used in the junction box or the connecting cables, although this is not necessary per se in the through junction box 72.
