Description

Die Erfindung betrifft eine geschirmte Anschlußeinrichtung für den Einbau in eine Wand oder ein Gestell, bei der mindestens ein mit einer Schirmung versehenes Versorgungskabel innenseitig an ein leitendes Gehäuse anschließbar und frontseitig mindestens ein zu einem Gerät führendes Anschlußkabel vorgesehen sind.The invention relates to a shielded connection device for installation in a wall or a frame, in which at least one supply cable provided with a shield can be connected on the inside to a conductive housing and at least one connection cable leading to a device is provided on the front.

Eine Anschlußeinrichtung dieser Art ist aus der WO-A- 87/07775 bekannt. Der Vorteil derartiger Anschlußeinrichtungen besteht darin, daß ein Gebäude vorverkabelt werden kann. Bei Bedarf werden die Anschlüsse für die jeweiligen Dienste später an den gewünschten Stellen hergestellt. Im Bedarfsfall wird ein zum jeweiligen Endgerät passender Adapter-Einsatz eingesteckt, während Änderungen an der Verkabelung im Inneren bzw. hinter der Anschlußeinrichtung nicht mehr durchgeführt werden müssen.A connection device of this type is known from WO-A-87/07775. The advantage of such connection devices is that a building can be pre-wired. If necessary, the connections for the respective services will be made later at the desired locations. If necessary, an adapter insert suitable for the respective end device is inserted, while changes to the wiring inside or behind the connection device no longer have to be carried out.

Bei derartigen Anschlußeinrichtungen muß eine ausreichende Abschirmung der im Inneren jeweils ungeschirmt verlaufenden Adern nach außen hin gewährleistet sein. Weiterhin ist auch im Bereich der Zugentlastung und der Schirmabfangung darauf zu achten, daß bei diesen Durchtrittstellen die Abschirmung nicht unterbrochen ist. Dies muß auch dann gelten, wenn größere Zugspannungen über das Kabel, z.B. auf die Anschlußeinrichtung, übertragen werden. Weiterhin soll die Zugentlastungsvorrichtung einfach montierbar und gut zugänglich sein, und schließlich ist ein Aufbau zweckmäßig, der für die verschiedenen Anschlußmöglichkeiten (Einzeldosen oder Mehrfachanschlüsse) gleichermaßen verwendbar ist, zumindest in den Grundbausteinen.In connection devices of this type, adequate shielding of the conductors running in the interior unshielded in each case from the outside must be ensured. Furthermore, in the area of strain relief and shield support, it must be ensured that the shielding is not interrupted at these passages. This must also apply if larger tensile stresses via the cable, e.g. be transferred to the connection device. Furthermore, the strain relief device should be easy to assemble and easily accessible, and finally a structure is expedient which can be used equally for the various connection options (single sockets or multiple connections), at least in the basic components.

Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußeinrichtung der eingangs genannten Art so weiterzubilden, daß diese allgemein verwendbar ist und neben einer sicheren Abfangung eine ausreichende Abschirmung auch im Bereich der Eintrittsstelle des Versorgungskabels gewährleistet.The invention has for its object to develop a connection device of the type mentioned that this is generally usable and, in addition to secure interception, also ensures adequate shielding in the area of the entry point of the supply cable.

Diese Aufgabe wird bei einer geschirmten Anschlußeinrichtung der eingangs genannten Art dadurch gelöst, daß für das Versorgungskabel eine mit einer entsprechenden Durchtrittsöffnung versehene leitende Zugentlastungsvorrichtung vorgesehen ist, welche auch der Abfangung der Schirmung dient, daß die Zugentlastungsvorrichtung zweiteilig ausgebildet ist und das Versorgungskabel zwischen sich einschließt und festklemmt und daß die Zugentlastungsvorrichtung mit dem Gehäuse elektrisch leitend verbunden ist.This object is achieved in a shielded connection device of the type mentioned in that a conductive strain relief device provided with a corresponding passage opening is provided for the supply cable, which also serves to intercept the shielding, that the strain relief device is formed in two parts and includes the supply cable between them and clamps and that the strain relief device is electrically connected to the housing.

Zugentlastung und Abfangung der Schirmung werden somit gemeinsam bewirkt, und durch die zweiteilige Ausbildung der Zugentlastungsvorrichtung ist die Montage in besonders einfacher und sicherer Weise durchführbar. Da die Zugentlastungsvorrichtung im montierten Zustand mit dem Gehäuse elektrisch leitend verbunden ist, wird hiermit auch eine gute und sichere Abschirmung gewährleistet.Strain relief and interception of the shielding are thus brought about together, and the two-part design of the strain relief device makes assembly particularly easy and reliable. Since the strain relief device is electrically conductively connected to the housing in the assembled state, this also ensures good and safe shielding.

Bei der Darstellung einer Anschlußeinrichtung nach Fig. 1 ist ein nur an der Vorderseite offenes Gehäuse GH vorgesehen, das aus Blech oder einem metallisierten Kunststoff besteht und somit als Abschirmung dient. Für den Anschluß eines Versorgungskabels (Nachrichtenkabels) VC für die verschiedenen Dienste (Telefon, Fax, Fernschreiben usw.) ist eine Zugentlastungsvorrichtung ZV vorgesehen, deren Aufbau im einzelnen anhand von Fig. 2 näher erläutert wird. Diese Zugentlastungsvorrichtung ZV besteht ebenfalls aus leitendem Material (z.B. Messing) oder aus einem metallisierten Kunststoff und ist mit der Abschirmung des Versorgungskabels VC leitend verbunden. Die Abmessungen der Zugentlastungsvorrichtung ZV sind so gewählt, daß diese genau in eine entsprechende Öffnung in dem Gehäuse ZV hineinpaßt und dieses hochfrequenzdicht verschließt. Hierzu ist im folgendem Beispiel an der Oberseite des Gehäuses GH über die Länge der Zugentlastungsvorrichtung ZV ein Blechlappen BL nach unten umgebogen, an dem die Außenfläche der Zugentlastungsvorrichtung ZV anliegt. Mittels zweier Schrauben SR1 und SR2, die durch die Rückseite des Gehäuses GH sowie durch entsprechende Bohrungen der Zugentlastungsvorrichtung ZV hindurchgehen, wird die Zugentlastungsvorrichtung ZV an dem Blech BL festgeschraubt. Die Schrauben SR1 und SR2 können gleichzeitig auch das Abfangen der Schirmung und die Zugentlastung mitbewirken, d.h. sie pressen die beiden Teile der Zugentlastungsvorrichtung ZV zusammen und bewirken auch deren Halterung im Gehäuse GH. Im fertig montierten Zustand ist durch die Zugentlastungsvorrichtung ZV die hochfrequenzmäßige Abdichtung des Gehäuses GH gewährleistet.1, a housing GH which is only open at the front is provided, which consists of sheet metal or a metallized plastic and thus serves as a shield. For the connection of a supply cable (communication cable) VC for the various services (telephone, fax, telex, etc.) a strain relief device ZV is provided, the structure of which is explained in more detail with reference to FIG. 2. This strain relief device ZV also consists of a conductive material (eg brass) or a metallized plastic and is conductively connected to the shielding of the supply cable VC. The dimensions of the strain relief device ZV are selected so that it fits exactly into a corresponding opening in the housing ZV and closes it in a radio-frequency-tight manner. For this purpose, in the following example, a sheet metal tab BL is bent down over the length of the strain relief device ZV on the upper side of the housing GH, against which the outer surface of the strain relief device ZV bears. The strain relief device ZV is screwed to the sheet metal BL by means of two screws SR1 and SR2 which pass through the rear of the housing GH and through corresponding bores in the strain relief device ZV. The screws SR1 and SR2 can at the same time also intercept the shielding and strain relief, ie they press the two parts of the strain relief device ZV together and also cause them to be held in the housing GH. In the fully assembled state, the strain relief device ZV ensures high-frequency sealing of the housing GH.

Im vorliegenden Beispiel ist angenommen, daß das Versorgungskabel VC vier elektrische Leiter (Adern AD1-AD4) aufweist, die zu einem entsprechenden Adapterstecker AS geführt sind. Dieser Adapterstecker AS ist im einzelnen näher in der Patentanmeldung P 41 03 928.9 beschrieben und weist an seiner Rückseite Schnellklemmeinrichtungen für eine bestimmte maximale Aderzahl auf (z.B. 8), während an der Vorderseite im Inneren des Schlitzes SL eine entsprechende Anzahl von (z.B. ebenfalls 8) Kontaktfedern vorgesehen ist. Der Adapterstecker AS ist normalerweise innerhalb des Gehäuses GH an dessen Rückseite fest angeordnet. Im vorliegenden Ausführungsbeispiels ist er zur besseren Darstellung etwas nach vorne herausgezeichnet.In the present example it is assumed that the supply cable VC has four electrical conductors (wires AD1-AD4) which are led to a corresponding adapter plug AS. This adapter plug AS is described in more detail in patent application P 41 03 928.9 and has on the rear side quick-clamping devices for a specific maximum number of wires (for example 8), while on the front inside the slot SL a corresponding number of (for example also 8) Contact springs is provided. The adapter plug AS is normally fixed inside the housing GH on the rear side. In the present exemplary embodiment, it is drawn out somewhat to the front for better illustration.

An der offenen Seite des Gehäuses GH sind leitende Schraubflächen SF1 und SF2 vorgesehen, die mit einer entsprechenden Öffnung für die Aufnahme einer (hier nicht dargestellten Schraube) versehen sind, durch die eine Frontplatte FP an dem Gehäuse GH befestigt werden kann. Die Frontplatte FP besteht aus Blech bzw. einem metallisierten Kunststoff und weist an den vier Seiten jeweils Montagebleche MP1-MP4 auf, die flächig ausgebildet sind und jeweils bogenförmig verlaufende Längsschlitze LS1-LS4 aufweisen, welche zur Montage an einer (hier nicht dargestellten) Wanddose (Leerdose) dienen. Die Frontplatte FP weist im Mittelteil einen Rahmen RA auf, der gegen über den Montageblechen MP1-MP4 hochgezogen ist und etwa L-förmigen Querschnitt hat. Mit diesem Rahmen RA wird die Frontplatte FP über die offene Vorderseite des Gehäuses GH gestülpt und dieses dadurch in seinem Frontbereich (bis auf die Öffnung OA) ebenfalls hochfrequenzdicht abgeschlossen. Über die Öffnungen OP1-OP4 kann jeweils die Schraubverbindung zu den Öffnungen OF1 und OF2 an den Schraubflächen des Gehäuses GH hergestellt werden. An beiden Seiten der Öffnung OA der Frontplatte FP sind Haltelaschen HL1 und HL2 vorgesehen, in welche ein Adaptereinsatz AE einrastbar ist, dessen Aufbau ebenfalls in der Patentanmeldung P 41 03 928.9 näher beschrieben ist. Hierzu sind an beiden Seiten des Adaptereinsatzes AE Rastnasen vorgesehen, wobei hier nur die linke Rastnase RN2 sichtbar ist. Diese Rastnasen greifen hinter die Haltelaschen HL1 und HL2 und arretieren dadurch den Adaptereinsatz AE in der Frontplatte FP. Der Adaptereinsatz AE weist eine Isolierstoffplatte IT auf, auf der eine Reihe von z.B. 8 Leiterbahnen L1-L8 vorgesehen sind. An diesem Adaptereinsatz wird in bekannter Weise ein Anschlußkabel AC angeschlossen, das zu einem entsprechenden Teilnehmergerät geführt ist, wobei für jeden Anschlußfall ein entsprechender Adaptereinsatz mit entsprechend positionierten bzw. verdrahteten Kontaktierungseinrichtungen vorgesehen ist. Beispielsweise werden für einen Telefonanschluß vier Anschlußdrähte benötigt, so daß vier der Leiterbahnen, z.B. L1-L4 beschaltet und z.B. mit den Adern AD1, AD2 und AD3 verbunden sind. Da der Anschluß an den korrespondierenden Anschlußstecker AS (bezüglich der Adern AD1-AD4) nach einem fest vorgegebenen Schema erfolgt, das dem jeweiligen Anschlußgerät zugeordnet ist, genügt es einen entsprechenden Adaptereinsatz AE anzubringen, um die Durchkontaktierung der vormontierten Adern AD1-AD4 mit den Leiterbahnen L1-L4 und damit den zugehörigen vier Adern des Anschlußkabels AC zu bewirken.On the open side of the housing GH, conductive screw surfaces SF1 and SF2 are provided, which are provided with a corresponding opening for receiving a screw (not shown here) through which a front plate FP can be attached to the housing GH. The front plate FP consists of sheet metal or a metallized plastic and has mounting plates MP1-MP4 on each of the four sides, which are flat and each have arc-shaped longitudinal slots LS1-LS4, which are for mounting on a wall box (not shown here) ( Empty can). The front plate FP has a frame RA in the middle part, which is pulled up relative to the mounting plates MP1-MP4 and has an approximately L-shaped cross section. With this frame RA, the front plate FP is slipped over the open front of the housing GH and this is also sealed in its front region (except for the opening OA) in a high-frequency manner. The screw connection can be opened via the openings OP1-OP4 to the openings OF1 and OF2 on the screw surfaces of the housing GH. Holding tabs HL1 and HL2 are provided on both sides of the opening OA of the front plate FP, into which an adapter insert AE can be snapped, the structure of which is also described in more detail in patent application P 41 03 928.9. For this purpose, locking lugs are provided on both sides of the adapter insert AE, only the left locking lug RN2 being visible here. These locking lugs reach behind the retaining tabs HL1 and HL2 and thereby lock the adapter insert AE in the front plate FP. The adapter insert AE has an insulating material plate IT on which a series of, for example, 8 conductor tracks L1-L8 are provided. In a known manner, a connecting cable AC is connected to this adapter insert, which leads to a corresponding subscriber device, a corresponding adapter insert with correspondingly positioned or wired contacting devices being provided for each connection case. For example, four connecting wires are required for a telephone connection, so that four of the conductor tracks, for example L1-L4, are connected and are connected, for example, to the wires AD1, AD2 and AD3. Since the connection to the corresponding connector plug AS (with regard to the wires AD1-AD4) is made according to a predetermined pattern that is assigned to the respective connection device, it is sufficient to attach an appropriate adapter insert AE in order to connect the pre-assembled wires AD1-AD4 to the conductor tracks L1-L4 and thus the associated four wires of the connection cable AC.

An der Rückseite der Frontplatte des Adaptereinsatzes AE ist ein am Rand geschlitzt ausgebildetes Kontaktierungsblech (Abschirmblech) KBL vorgesehen, das auf der Frontseite des Rahmen RA aufliegt und diesen bis auf die ebenfalls hochfrequenzdicht abgeschlossene Durchtrittsstelle für das Anschlußkabel AC abschließt. Die Rückseite der Frontplatte des Adaptereinsatzes kann auch metallisiert sein. Normalerweise ist auch das Anschlußkabel AC geschirmt, so daß die Gesamtanordnung im zusammengebauten Zustand eine vollständig geschirmte Anschlußeinrichtung ergibt. Dabei wird die Abdeckblende ABL (z.B. aus Kunststoff) an der Vorderseite angebracht.On the rear of the front plate of the adapter insert AE, a contact plate (shielding plate) KBL with a slot is provided, which rests on the front of the frame RA and closes it apart from the passage point for the connecting cable AC, which is also sealed with high frequency resistance. The back of the front plate of the adapter insert can also be metallized. The connecting cable AC is normally also shielded, so that the overall arrangement, when assembled, results in a completely shielded connecting device. The ABL cover (e.g. made of plastic) is attached to the front.

In Fig. 2 ist in perspektivischer Darstellung eine Zugentlastungsvorrichtung ZV dargestellt, die aus zwei gleichen Blöcken Z1 und Z2 besteht. Im vorliegenden Beispiel ist angenommen, daß drei Versorgungskabel VC1-VC3 angeschlossen werden sollen, die in entsprechenden Bohrungen untergebracht sind, wobei diese je zur Hälfte in dem Block Z1 und Z2 liegen. Die Abschirmung der Versorgungskabel VC1-VC3 wird im Bereich der Zugentlastungsvorrichtung ZV freigelegt und nach hinten auf den Kabelmantel gelegt, so daß eine Kontaktierung zwischen der Zugentlastungsvorrichtung und dieser Abschirmung hergestellt werden kann. Es kann zweckmäßig sein, die Schirmung VA1-VA3 der Versorgungskabel VC1-VC3 zusätzlich durch eine leitende Folie (z.B. Kupferfolie) FO1-FO3 im Bereich der Zugentlastungsvorrichtung ZV zu umwickeln. Die Dimensionierung der Bohrungen erfolgt so, daß ein ausreichend hoher Anpreßdruck auf die Versorgungskabel VC1-VC3 erzielt wird, d.h. die Bohrungen sind in ihrem Durchmesser kleiner zu wählen als der Außendurchmesser des freigelegten Geflechtes VA1-VA3 bzw. der Außendurchmesser zusammen mit den Folien FO1-FO3.In Fig. 2, a strain relief device ZV is shown in perspective, which consists of two identical blocks Z1 and Z2. In the present example, it is assumed that three supply cables VC1-VC3 are to be connected, which are accommodated in corresponding holes, half of which are located in blocks Z1 and Z2. The shielding of the supply cable VC1-VC3 is exposed in the area of the strain relief device ZV and placed on the back of the cable sheath so that contact can be established between the strain relief device and this shield. It may be appropriate to additionally wrap the shield VA1-VA3 of the supply cable VC1-VC3 with a conductive foil (e.g. copper foil) FO1-FO3 in the area of the strain relief device ZV. The holes are dimensioned so that a sufficiently high contact pressure on the supply cables VC1-VC3 is achieved, i.e. The diameter of the holes should be smaller than the outside diameter of the exposed braid VA1-VA3 or the outside diameter together with the foils FO1-FO3.

Dabei ist es zweckmäßig, nicht mit gerade durchgehenden Öffnungen gleichen Durchmessers zu arbeiten, sondern eine Ausführungsform gemäß Fig. 3 vorzusehen. Dort ist die Bohrung für den Anschluß z.B. eines Versorgungskabels VC1 im Bereich der Zugentlastungsvorrichtung ZV zweistufig ausgebildet, wobei eine engere Bohrung BO11 auf der dem Versorgungskabel VC1 zugewandten Seite vorgesehen ist, während eine erweiterte Bohrung BO12 im Bereich der austretenden Adern AD1-AD4 vorhanden ist. Dies hat zur Folge, daß das Isoliermaterial der Kabelseele des Versorgungskabels VC1 durch den verringerten Querschnitt im Bereich der Bohrung BO11 beim Zusammenpressen fließt und dadurch mit in die erweiterte Bohrung BO12 hineingedrückt wird. Der so im Bereich der Bohrung BO12 sich ergebende verbreiterte Wulst liefert somit eine besonders gute und zuverlässige Zugentlastung gegen Zugkräfte PZ, welche in Längsrichtung an dem Versorgungskabel VC1 angreifen. Dies ist besonders deshalb von Bedeutung, weil bei der Montage derartige Kräfte PZ in nicht unerheblichen Ausmaß auftreten können.It is expedient not to work with straight openings of the same diameter, but to provide an embodiment according to FIG. 3. There, the hole for the connection, for example, of a supply cable VC1 in the area of the strain relief device ZV is formed in two stages, a narrower hole BO11 being provided on the side facing the supply cable VC1, while an enlarged hole BO12 is present in the area of the emerging wires AD1-AD4. The result of this is that the insulating material of the cable core of the supply cable VC1 flows through the reduced cross section in the area of the hole BO11 when it is pressed together and is thereby pressed into the enlarged hole BO12. The widened bead thus resulting in the area of the bore BO12 thus provides particularly good and reliable strain relief against tensile forces PZ which act on the supply cable VC1 in the longitudinal direction. This is particularly important because during assembly such PZ forces can occur to a not inconsiderable extent.

Die Dimensionierung des Innendurchmessers D2 der Bohrung BO12 erfolgt so, daß dieser etwa dem Außendurchmesser D1 des Versorgungskabels VC1 entspricht um eine ausreichende Andruckkraft zu erzeugen. Dagegen sollte der verringerte Durchtrittsbereich d der Bohrung BO1 zweckmäßig zwischen 2 und 10 % geringer gewählt werden als der Außendurchmesser D1 des Versorgungskabels VC1.The inner diameter D2 of the bore BO12 is dimensioned such that it corresponds approximately to the outer diameter D1 of the supply cable VC1 in order to generate a sufficient pressing force. In contrast, the reduced passage area d of the bore BO1 should expediently be chosen to be between 2 and 10% smaller than the outer diameter D1 of the supply cable VC1.

Aus Fig. 2 ist ferner ersichtlich, daß zum Zusammenhalten der beiden Blöcke Z1 und Z2 Halteschrauben SR1 und SR2 vorgesehen sind. Diese Halteschrauben SR1 und SR2 gehen durch Bohrungen OK1 und OK2 in dem Block Z1 und OK3 und OK4 im Block Z2 hindurch und werden schließlich wie aus Fig. 1 ersichtlich, in das abgebogene Blechteil BL eingeschraubt, wobei es zweckmäßig ist, selbstschneidende Blechschrauben für SR1 und SR2 zu verwenden.From Fig. 2 it can also be seen that holding screws SR1 and SR2 are provided to hold the two blocks Z1 and Z2 together. These retaining screws SR1 and SR2 pass through holes OK1 and OK2 in block Z1 and OK3 and OK4 in block Z2 and are finally screwed into the bent sheet metal part BL, as can be seen in FIG. 1, whereby it is expedient to use self-tapping sheet metal screws for SR1 and Use SR2.

Es ist normalerweise erforderlich, daß das Gehäuse GH in Fig. 1 auch bei einer leeren, d.h. nicht mit einem Kabel bestückten Anordnung geschirmt gehalten wird. Deshalb werden die Blöcke Z1 und Z2 mit jeweils zwei weiteren Bohrungen OK11 und Ok12 bzw. OK23 und OK24 versehen, die den gleichen Abstand haben wie die Bohrungen OK1 und OK2 bzw. OK3 und OK4 und zudem diese Bohrungen durchdringen. Zur Abdeckung der Durchtrittsöffnungen in den beiden Körpern Z1 und Z2 braucht somit lediglich jeder dieser Körper um jeweils 90° gegenüber der Anordnung nach Fig. 2 gedreht zu werden, wodurch die Öffnungen OK11 und OK23 einerseits sowie OK12 und OK24 andererseits ebenfalls eine durchgehende Bohrung ergeben, in die die Halteschrauben SR1 und SR2 eingeschraubt werden können und so eine Abdichtung der Eintrittsstelle des Gehäuses GH ergeben. An dem Gehäuse GH liegen dann nämlich die ebenen Seitenflächen an und bilden ein geschlossenes Gebilde, das die Eintrittsöffnung hochfrequenzdicht abschließt.It is normally necessary for the housing GH in FIG. 1 to be shielded even when the arrangement is empty, ie not equipped with a cable. For this reason, blocks Z1 and Z2 are each provided with two further holes OK11 and Ok12 or OK23 and OK24, which have the same distance as the holes OK1 and OK2 or OK3 and OK4 and also penetrate these holes. To cover the passage openings in the two bodies Z1 and Z2, it is therefore only necessary for each of these bodies to be rotated by 90 ° with respect to the arrangement according to FIG. 2, as a result of which the openings OK11 and OK23 on the one hand and OK12 and OK24 on the other hand also result in a continuous bore, into which the retaining screws SR1 and SR2 can be screwed, thus sealing the entry point of the housing GH. The flat side surfaces then lie against the housing GH and form a closed structure which closes the inlet opening in a radio-frequency-tight manner.

In Fig. 4 ist eine Abwandlung des in Fig. 1 dargestellten Gehäuses GH dargestellt und mit GH1 bezeichnet. Dieses Gehäuse ist gegenüber dem Gehäuse GH nach Fig. 1 lediglich insoweit abgewandelt, als die Zugentlastungsvorrichtung ZV (die ebenso ausgebildet ist wie bei Fig. 1 oder Fig. 2 und 3), im Bereich der Rückwand des Gehäuses GH1 abgesenkt angeordnet ist. Hierzu wird die Blechlasche BL1 gegenüber Fig. 1 weiter nach unten gebogen und aus den beiden Seitenwänden sowie aus der Rückwand ein größerer Ausschnitt herausgenommen, so daß die Zugentlastungsvorrichtung ZV gegenüber der Außenkontur des kubischen Gehäuses abgesenkt ist. Diese Absenkung hat den Zweck, daß das Versorgungskabel VC weniger scharf geknickt wird, wenn eine Montage in einem engen Gehäuse, z.B. einer Wanddose WD erfolgen muß. Um die verschiedenen Adern AD1-AD4 anschließen zu können und auch die Zugentlastungsvorrichtung ZV mit dem Kabel VC zu verbinden, ist es notwendig, dieses Kabel entsprechend weit aus der Wanddose WD herauszuziehen und die notwendigen Schraub- und Kontaktverbindungen anzubringen. Nach Beendigung dieser Montagearbeiten, die in einer Entfernung von etwa 10-15 cm vor der Wanddose WD durchgeführt werden, wird das komplette Gehäuse GH1 in die Wanddose eingeführt. Dabei ist es notwendig, daß für die nunmehr verbleibende Überlänge von ebenfalls 10-15 cm des Versorgungskabels VC eine Unterbringungsmöglichkeit gefunden wird. Am einfachsten kann diese Unterbringungsmöglichkeit dadurch realisiert werden, daß das gesamte Gehäuse GH so lange um seine Achse gedreht wird, bis die Überlänge des Versorgungskabels VC praktisch in Schleifen um das Gehäuse GH1 herum "aufgetrommelt" ist. Im vorliegenden Beispiel ist angenommen, daß das Kabel VC von rechts aus der Wand kommt und in die Wanddose WD durch eine entsprechende Öffnung eintritt. Die Aufnahme der Überlänge des Versorgungskabels VC entspricht hier etwa einem Viertel des Gehäuses GH1, wobei jedoch darauf hinzuweisen ist, daß natürlich auch ein Mehrfaches dieses Wertes "aufgetrommelt" werden kann. Beispielsweise könnte auch das Kabel VC von links kommen und es würde dann die Vorratslänge in einer etwa 75 % igen Umschlingung des Gehäuses GH1 untergebracht werden. Die Absenkung der Zugentlastungsvorrichtung ZV sollte mindestens um einen solchen Wert vorgenommen werden, der etwa dem maximalen Durchmesser des größten anzuschließenden Versorgungskabels VC entspricht. Zweckmäßig beträgt aber die Absenkung etwa zwischen dem zwei- und vierfachen des Durchmessers des größten anzuschließenden Versorgungskabels VC.FIG. 4 shows a modification of the housing GH shown in FIG. 1 and designated GH1. This housing is modified compared to the housing GH according to FIG. 1 only to the extent that the strain relief device ZV (which is designed in the same way as in FIGS. 1 or 2 and 3) is arranged in a lowered manner in the region of the rear wall of the housing GH1. For this purpose, the sheet metal bracket BL1 is bent further downward compared to FIG. 1 and a larger section is removed from the two side walls and from the rear wall, so that the strain relief device ZV is lowered relative to the outer contour of the cubic housing. The purpose of this lowering is that the supply cable VC is bent less sharply if it has to be installed in a narrow housing, for example a wall socket WD. In order to be able to connect the different wires AD1-AD4 and also to connect the strain relief device ZV with the cable VC, it is necessary to pull this cable out of the wall socket WD accordingly and to attach the necessary screw and contact connections. After completing this assembly work, which is carried out at a distance of about 10-15 cm in front of the wall socket WD, the complete housing GH1 is inserted into the wall socket. It is necessary to find an accommodation for the remaining excess length of 10-15 cm of the supply cable VC. The simplest way to implement this accommodation option is to rotate the entire housing GH around its axis until the excess length of the supply cable VC has practically been "rolled up" in loops around the housing GH1. In the present example it is assumed that the cable VC comes out of the wall from the right and enters the wall socket WD through a corresponding opening. The inclusion of the excess length of the supply cable VC corresponds here to about a quarter of the housing GH1, although it should be pointed out that a multiple of this value can of course also be "drummed". For example, the cable VC could also come from the left and the supply length would then be accommodated in an approximately 75% loop of the housing GH1. The lowering the strain relief device ZV should be carried out at least by a value which corresponds approximately to the maximum diameter of the largest supply cable VC to be connected. However, the reduction is expediently between approximately two and four times the diameter of the largest supply cable VC to be connected.

In Figur 5 ist eine Anordnung dargestellt, bei der drei Baueinheiten nebeneinander angeordnet werden können. Hierzu ist ein gemeinsames rechteckiges Gehäuse GH2 aus leitendem Material vorgesehen, bei dem nur die Frontseite offen ist und das an einer Längskante eine Aussparung AG aufweist. Diese Aussparung ist so dimensioniert, daß in ihr eine Zugentlastungsvorrichtung ZV Platz findet, wobei hier der Einfachheit halber die zugehörigen drei Anschlußkabel weggelassen sind. Die Befestigung der Zugentlastungsvorrichtung ZV erfolgt an dem nach innen umgebogenen Blechlappen BL1 über durch die entsprechenden Bohrungen BZ11 und BZ12 sowie BZ1 und BZ2 (bei ZV) hindurchtretende, hier nicht näher dargestellte Befestigungsschrauben analog zur Ausführungsform nach Figur 1. Dabei dichtet die Zugentlastungsvorrichtung ZV hochfrequenzmäßig den durch die Aussparung AG gebildeten Ausschnitt im montierten Zustand ab.FIG. 5 shows an arrangement in which three structural units can be arranged side by side. For this purpose, a common rectangular housing GH2 made of conductive material is provided, in which only the front side is open and which has a cutout AG on one longitudinal edge. This recess is dimensioned so that there is space for a strain relief device ZV, with the associated three connecting cables being omitted here for the sake of simplicity. The strain relief device ZV is fastened to the inwardly bent sheet metal tab BL1 via fastening screws, not shown here, which pass through the corresponding bores BZ11 and BZ12 and BZ1 and BZ2 (in the case of ZV) analogously to the embodiment according to FIG cutout formed by the recess AG in the assembled state.

Auf der Vorderseite des Gehäuses GH2 wird ein Montagerahmen MR angebracht, der aus leitendem Material besteht und drei Öffnungen OA1, OA2 und OA3 aufweist, welche zur Aufnahme von Adaptereinsätzen (hier nicht dargestellt) dienen, die ebenso aufgebaut sind wie der Adaptereinsatz AE in Figur 1. Der Montagerahmen MR entspricht somit in seiner Funktionsweise dem Rahmen RA nach Figur 1. Im Inneren des Gehäuses GH2 sind drei Adapterstecker AS1, AS2 und AS3 befestigt, die dem Adapterstecker AS nach Figur 1 entsprechen. Die Halterung des Montagerahmens MR erfolgt über Distanzstücke DS1 und DS2, die an der Rückwand bzw. falls vorhanden einer Zwischenwand des Gehäuses GH2 angreifen. An dem Montagerahmen MR sind weiterhin zwei Bohrungen BM1 und BM2 vorgesehen, deren Abstand entsprechend dem Abstand der Bohrungen BZ1 und BZ2 der Zugentlastungsvorrichtung ZV gewählt sind und die im montierten Zustand auch fluchtend zu den Bohrungen BZ11 und BZ12 in dem gebogenen Blechlappen BL2 verlaufen. Dadurch kann durch eine eingedrehte Schraube sowohl die Halterung des Montagerahmens MR an dem Gehäuse GH2 als auch gleichzeitig die Befestigung und gegebenenfalls Kontaktierung der Zugentlastungsvorrichtung ZV sowie deren Halterung am Gehäuse GH2 erfolgen. Die Halterung der anderen Seite des Montagerahmens MR erfolgt durch Halteschrauben, die in die Bohrungen BM3 und BM4 eingesteckt werden und die ihren Halt in den entsprechenden Bohrungen an den Schraubflächen SF3 und SF4 finden. Die außen aufzubringende Abdeckung AB zum Beispiel aus einem Kunststoffmaterial entspricht in ihrer Funktion der Abdeckung AB nach Figur 1, das heißt sie schließt das gesamte in eine Wand oder ein Gehäuse, ein Gestell oder dergleichen eingebaute Gehäuseteil GH2 nach außen ab.On the front of the housing GH2, a mounting frame MR is attached, which consists of conductive material and has three openings OA1, OA2 and OA3, which serve to receive adapter inserts (not shown here), which are constructed in the same way as the adapter insert AE in FIG. 1 The functioning of the mounting frame MR thus corresponds to that of the frame RA according to FIG. 1. Three adapter plugs AS1, AS2 and AS3 are fastened inside the housing GH2 and correspond to the adapter plug AS according to FIG. The mounting frame MR is held by spacers DS1 and DS2, which engage on the rear wall or, if present, an intermediate wall of the housing GH2. Two bores BM1 and BM2 are further provided on the mounting frame MR, the spacing of which corresponds to the spacing of the bores BZ1 and BZ2 of the strain relief device ZV are selected and they also run in alignment with the holes BZ11 and BZ12 in the bent sheet metal tab BL2 in the assembled state. As a result, both the mounting frame MR can be held on the housing GH2 by means of a screwed-in screw and the fastening and optionally contacting of the strain relief device ZV and its mounting on the housing GH2 can take place at the same time. The other side of the mounting frame MR is held in place by retaining screws which are inserted into the holes BM3 and BM4 and which are held in the corresponding holes on the screw surfaces SF3 and SF4. The function of the cover AB to be applied, for example made of a plastic material, corresponds to that of the cover AB according to FIG. 1, that is to say it closes off the entire housing part GH2 installed in a wall or a housing, a frame or the like.

Es ist auch möglich, die Zugentlastungsvorrichtung ZV an einem entsprechenden Ausschnitt an einer der hinteren Kanten des Gehäuses GH2 anzubringen, ähnlich wie dies bei dem Gehäuse GH nach Figur 1 der Fall ist. Es ist zweckmäßig, die Zugentlastungsvorrichtung ZV an einer der Schmalseiten des Gehäuses GH2 anzubringen bzw. dort in dieses einzulassen.It is also possible to attach the strain relief device ZV to a corresponding cutout on one of the rear edges of the housing GH2, similar to the case with the housing GH according to FIG. 1. It is expedient to attach the strain relief device ZV to one of the narrow sides of the housing GH2 or to let it in there.

Es ist auch möglich, in dem Montagerahmen MR mehrere Reihen von parallel zueinander verlaufenden Öffnungen vorzusehen, wenn entsprechend viele (zum Beispiel 16) Adaptereinsätze benötigt werden. Dann kann die Aufteilung so erfolgen, daß in einer unteren Reihe im Montagerahmen MR acht Öffnungen analog OA1 bis OA3 vorgesehen werden und darüber in einer zweiten Reihe nochmals acht Öffnungen.It is also possible to provide a plurality of rows of openings running parallel to one another in the mounting frame MR if a correspondingly large number (for example 16) of adapter inserts is required. The division can then take place in such a way that eight openings analogous to OA1 to OA3 are provided in a lower row in the mounting frame MR and another eight openings in a second row.

In Figur 6 ist eine Abwandlung der Anordnung nach Figur 5 dargestellt, welche das gleiche Gehäuse GH2 verwendet und ebenfalls drei Adapterstecker AS1 bis AS3 aufweist. Zur Verdeutlichung sind hier die Adapterstecker AS1 bis AS3 getrennt, das heißt im demontierten Zustand dargestellt und es sind hier auch die Adern des Versorgungskabels VC sichtbar, das mit Hilfe der Zugentlastungsvorrichtung ZV abgefangen wird.FIG. 6 shows a modification of the arrangement according to FIG. 5, which uses the same housing GH2 and also has three adapter plugs AS1 to AS3. For the sake of clarity, the adapter plugs AS1 to AS3 are separated, that is, shown in the disassembled state, and they are here the wires of the supply cable VC are also visible, which is intercepted with the help of the strain relief device ZV.

Unterschiedlich ist hier, daß zur Bildung einer Schräg-Auslaßdose zum Beispiel für einen Wandkanal oder einen Bodentank der Montagerahmen MR2 zwar bündig auf der freien (offenen) Stirnfläche des Gehäuses GH2 aufliegt, jedoch die Öffnungen OA1 bis OA3 für die Aufnahme der Adaptereinsätze nicht in der Ebene der offenen Stirnfläche des Gehäuses GH2 verlaufend angeordnet sind. Hierzu ist aus dem Montagerahmen MR ein Teilbereich MRT lappenförmig herausgebogen und verläuft unter einem Winkel zum Beispiel zwischen 30 und 60° zur Ebene des eigentlichen Montagerahmens MR2. Auf diese Weise liegen die Adaptereinsätze im eingeführten Zustand nicht mehr bündig zur vorderen Stirnfläche der Abdeckung AB2 sondern sind im unteren Teil versenkt in dieser Abdeckung angeordnet. Dies ermöglicht ein Herausführen von Anschlußkabeln in der richtigen Winkellage. Die Halterung des Montagerahmens MR2 an dem Gehäuse GH2 erfolgt zum Beispiel durch Distanzstücke DS4 und DS5 (beispielsweise in Form von Schweißbolzen), die sich bis ins Innere des Gehäuses GH2 bzw. bis zu dessen Rückwand bzw. einer etwaigen Zwischenwand erstrecken. Die Anschlußstücke AS1 bis AS3 können an einer Zwischenwand bzw. einem Halteblech (ähnlich Fig. 7) z.B. rastend gehalten werden, die im Inneren des Gehäuses GH2 angeordnet ist.The difference here is that to form an inclined outlet socket for a wall duct or a floor tank, for example, the mounting frame MR2 lies flush on the free (open) end face of the housing GH2, but the openings OA1 to OA3 for receiving the adapter inserts are not in the Level of the open end face of the housing GH2 are arranged extending. For this purpose, a sub-area MRT is bent out of the mounting frame MR in the form of a tab and extends at an angle, for example between 30 and 60 °, to the plane of the actual mounting frame MR2. In this way, in the inserted state, the adapter inserts are no longer flush with the front end face of the cover AB2 but are arranged in the lower part in this cover. This enables connection cables to be led out in the correct angular position. The mounting frame MR2 is held on the housing GH2, for example, by spacers DS4 and DS5 (for example in the form of welding bolts), which extend into the interior of the housing GH2 or up to its rear wall or any intermediate wall. The connectors AS1 to AS3 can be attached to an intermediate wall or a holding plate (similar to Fig. 7) e.g. are held latching, which is arranged inside the housing GH2.

In den Figuren 7, 8 und 9 ist dargestellt, wie eine abgewandelte Ausführungsform zu der Anordnung nach Figur 5 ausgestaltet werden kann. Dabei ist in einem großen Gehäuse GH3 ein Halteblech HB angebracht, das vom Boden bis zur Decke reicht und z.B über entsprechende Laschen LA1 und LA2 an dem Gehäuse GH3 befestigt ist. Das Gehäuse GH3 kann Bestandteil einer größeren Gestell-Baueinheit zum Beispiel eines Verteilerschrankes oder dergleichen sein, oder aber in eine entsprechend große Wand- oder Bodenöffnung eingefügt werden.FIGS. 7, 8 and 9 show how a modified embodiment of the arrangement according to FIG. 5 can be designed. In this case, a holding plate HB is attached in a large housing GH3, which extends from the floor to the ceiling and, for example, is fastened to the housing GH3 via corresponding tabs LA1 and LA2. The housing GH3 can be part of a larger frame assembly, for example a distribution cabinet or the like, or can be inserted into a correspondingly large wall or floor opening.

In Figur 9 ist dargestellt, wie dieses Halteblech HB im einzelnen aufgebaut ist. Dabei sind zwei Reihen von Öffnungen OE11 bis OE14 und darunter OE21 bis OE24 vorgesehen, in die Adapterstecker eingesetzt werden können, die analog dem Adapterstecker AS1 nach Figur 1 aufgebaut und entsprechend mit hier nicht näher dargestellten Adern von Versorgungskabeln beschaltet sind. In Figur 7 ist einer dieser Adapterstecker AS1 gezeichnet, wobei ersichtlich ist, daß dieser über eine Rastnase RN, welche in die entsprechende Zusatzöffnung OEA11 in Fig. 9 paßt, in der Öffnung OE1 des Halteblechs HB rastend gehalten ist.FIG. 9 shows how this holding plate HB in detail is constructed. Two rows of openings OE11 to OE14 and below that OE21 to OE24 are provided, into which adapter plugs can be inserted, which are constructed analogously to the adapter plug AS1 according to FIG. 1 and are accordingly connected to wires of supply cables, not shown here. FIG. 7 shows one of these adapter plugs AS1, whereby it can be seen that it is held in a latching manner in the opening OE1 of the holding plate HB via a locking lug RN which fits into the corresponding additional opening OEA11 in FIG. 9.

Die zugehörige Frontplatte bzw. der Montagerahmen MR3 ist in Figur 8 dargestellt und weist zwei Reihen von Öffnungen OA11 bis OA14 sowie OA21 bis OA24 auf, deren Gestaltung den Öffnungen OA1 bis OA3 nach Figur 5 entspricht. Somit können in ihnen die jeweiligen Adaptereinsätze AE rastend eingeschoben werden, wobei sie durch Rastnasen (entsprechend RN2 bei Figur 1) an entsprechenden Haltelaschen (entsprechend HL1 in Figur 1) gehalten werden. Die Öffnungen OE11 bis OE24 sind bezüglich der Öffnungen OA11 bis OA24 in dem Montagerahmen MR3 so gehalten, daß die Anschlußstecker zum Beispiel AS1 in den Öffnungen OE11 bis OE24 des Halteblechs HB genau fluchtend für die Aufnahme der die Anschlußleitungen tragenden Isolierstoffplatte IP1 (Bestandteil des jeweiligen Adaptereinsatzes z.B. AE1) ausgerichtet sind und diese unter Kontaktierung nach dem Einschieben ortsgenau aufnehmen. In Figur 7 ist ein Teil der Isolierplatine IP1 des Adaptereinsatzes AE1 sichtbar; der linke Teil dieser Platine ist gestrichelt gezeichnet, weil er im montierten Zustand in das Innere des Adaptersteckers AS1 eintaucht. Der Montagerahmen MR3 wird über entsprechende Befestigungseinrichtungen an frontseitigen Haltelaschen LA3 und LA4 des Gehäuses GH3 befestigt.The associated front plate or the mounting frame MR3 is shown in FIG. 8 and has two rows of openings OA11 to OA14 and OA21 to OA24, the design of which corresponds to the openings OA1 to OA3 according to FIG. The respective adapter inserts AE can thus be inserted in a latching manner, wherein they are held by corresponding latches (corresponding to RN2 in FIG. 1) on corresponding retaining tabs (corresponding to HL1 in FIG. 1). The openings OE11 to OE24 are held with respect to the openings OA11 to OA24 in the mounting frame MR3 in such a way that the connecting plugs, for example AS1, in the openings OE11 to OE24 of the holding plate HB are exactly aligned for the reception of the insulating material plate IP1 (part of the respective adapter insert) eg AE1) are aligned and pick them up with contact after insertion. FIG. 7 shows a part of the insulating board IP1 of the adapter insert AE1; the left part of this circuit board is drawn in dashed lines because it dips into the interior of the adapter plug AS1 when assembled. The mounting frame MR3 is fastened to the front mounting brackets LA3 and LA4 of the housing GH3 using appropriate fastening devices.

An der Rückseite des Gehäuses GH3 sind ein oder mehrere Durchbrüche DB für die Zuführung von Kabeln vorgesehen, welche der Beschaltung bzw. Verdrahtung der Adapterstecker zum Beispiel AS1 dienen. Im fertig bestückten Zustand kann zum Beispiel ein Gehäuse GH3 nach Figur 7 insgesamt sechzehn Adaptereinsätze ähnlich AE1 aufnehmen, und zwar jeweils in zwei Reihen zu je acht.At the rear of the housing GH3, one or more openings DB are provided for the supply of cables, which are used for wiring or wiring the adapter plug, for example AS1. For example, when fully assembled a housing GH3 according to FIG. 7 accommodate a total of sixteen adapter inserts similar to AE1, in each case in two rows of eight each.

In Fig. 10 ist eine Wanddose dargestellt, die in eine nur mit der Begrenzung angedeutete Wand WA eingelassen ist und deren Dosenkörper, wie in Fig. 4 mit WD bezeichnet ist. Auch das geschirmte Gehäuse GH1 hat den gleichen Aufbau wie bei Fig. 4 und auch die Zugentlastungsvorrichtung ZV und das Versorgungskabel VC entsprechen den dort beschriebenen Teilen. Im Unterschied zur Anordnung nach Fig. 4 ist jedoch die Anordnung des Gehäuses GH1 in der Wanddose WD schräg vorgenommen, d.h. das Gehäuse liegt zum Teil in der Wanddose WD und ragt zum Teil aus dieser Wanddose WD nach vorne heraus. Im unteren Teil des Gehäuses GH ist der Adapterstecker AS vorgesehen, der mit einem Adaptereinsatz AE (vergleiche Fig. 1) bei Bedarf bestückt werden kann, wobei dann ein Anschlußkabel AC zu dem jeweiligen zu versorgenden Gerät führt. Das Innere des Adapter einsatzes AE mit seiner Kontakteinrichtung CE ist über die Isolierplatine IP mit dem Adapterstecker AS verbunden. Der Austritt des Anschlußkabels AC erfolgt demgemäß schräg nach unten. Die Frontplatte FP1 entspricht im wesentlichen in ihrem Aufbau der Frontplatte FP nach Fig. 1 und ebenso die aus Kunststoff bestehende Abdeckung AB1 der Abdeckung AB nach Fig. 1. Zusätzlich vorgesehen ist hier lediglich eine spezielle Abdeckhaube AH, welche mit Rastnasen RAH versehen ist und in die frontseitige Öffnung in der Abdeckung AB1 hineingedrückt werden kann und an der Rückseite der Frontplatte FP1 rastend gehalten ist. Diese Abdeckung AH besteht zweckmäßig aus Kunststoff und umschließt an drei Seiten das aus der Wanddose WD herausragende Gehäuse GH1. Lediglich an ihrer Unterseite weist die Abdeckung AH eine Öffnung auf, die so gestaltet ist, daß der Adaptereinsatz AE eingeführt werden kann.FIG. 10 shows a wall box which is embedded in a wall WA which is only indicated with the limitation and whose box body is designated WD in FIG. 4. The shielded housing GH1 also has the same structure as in FIG. 4 and the strain relief device ZV and the supply cable VC also correspond to the parts described there. In contrast to the arrangement according to FIG. 4, however, the arrangement of the housing GH1 in the wall socket WD is made obliquely, i.e. the housing is partly in the wall socket WD and partly protrudes from this wall socket WD to the front. In the lower part of the housing GH, the adapter plug AS is provided, which can be equipped with an adapter insert AE (see FIG. 1) if necessary, in which case a connecting cable AC leads to the respective device to be supplied. The interior of the adapter insert AE with its contact device CE is connected to the adapter plug AS via the insulating board IP. The connection cable AC therefore emerges obliquely downwards. The front panel FP1 essentially corresponds in its construction to the front panel FP according to FIG. 1 and likewise the cover AB1 made of plastic of the cover AB according to FIG the front opening in the cover AB1 can be pushed in and is held in place on the back of the front panel FP1. This cover AH suitably consists of plastic and encloses the housing GH1 protruding from the wall socket WD on three sides. Only on its underside does the cover AH have an opening which is designed such that the adapter insert AE can be inserted.
