Description

Die Erfindung betrifft eine Zweifach-Abzweigdose mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a double junction box with the features of the preamble of Claim 1.

Es ist bekannt, zur Stromverteilung z.B. in Haushalten von einer Hauptstromleitung einzelne Nebenleitungen abzuzweigen. Hierzu werden Abzweigdosen verwendet, die beispielsweise den Strom für die Beleuchtung eines Raumes abzweigen. Als Hauptstromleitung wird üblicherweise ein mehradriges Leitungskabel, d.h ein mehradriges Flachbandkabel verwendet.It is known to use e.g. in households from a main power line to branch individual branch lines. Junction boxes are used for this, which, for example, branch off the electricity for lighting a room. A multi-core cable, i.e. used a multi-core ribbon cable.

Aus DE-A-2 507 130 ist eine Einfach-Abzweigdose bekannt, deren Abzweigdosengehäuse aus vielen einzelnen Gehäuseschichten zusammengesetzt ist. Die Gehäuseschichten weisen einerseits eine fertigungstechnisch komplizierte Oberflächengestalt auf und müssen andererseits umständlich aneinander fixiert werden, um im Montagezustand als Einheit zu wirken. Aufgrund des voluminösen Aufbaus des Abzweigdosengehäuses ist die zwischen zwei benachbarten Gehäuseschichten am Gehäuserand vorgesehene Verschraubung nicht ausreichend, um die einzelnen Bestandteile des Abzweigdosengehäuses auch bei äußeren Krafteinwirkungen dauerhaft aneinanderzuhalten. Im Montagezustand liegt das Flachbandkabel zwischen einer Bodenschale und dem übrigen Abzweigdosengehäuse ein. Die Bodenplatte ist jedoch schwenkbar am Abzweigdosengehäuse gelagert, so daß ein großer Schwenkweg erforderlich ist, um das Flachbandkabel in das Abzweigdosengehäuse einzulegen oder auch herauszunehmen. Diese Arbeitsschritte sind aufgrund der üblicherweise beengten Platzverhältnisse am Montageort für den Monteur umständlich und unbequem.From DE-A-2 507 130 a single junction box is known, the junction box housing is composed of many individual housing layers. The On the one hand, housing layers have a surface shape that is complicated in terms of production technology and, on the other hand, have to be laboriously fixed to each other, to act as a unit when assembled. Because of the voluminous The structure of the junction box housing is that between two adjacent housing layers The screw connection provided on the edge of the housing is not sufficient to the individual components of the junction box housing even when subjected to external forces stick together permanently. The ribbon cable is in the installed state between a bottom shell and the rest of the junction box on. However, the base plate is pivotally mounted on the junction box housing, so that a large swivel path is required to insert the ribbon cable into the Insert or remove junction box housing. These steps are due to the usually limited space at the installation site cumbersome and uncomfortable for the fitter.

Das vorbekannte Abzweigdosengehäuse weist außerdem eine Abzweigbuchse für die elektrische Verbindung eines als Hauptstromleitung wirksamen Flachbandkabels mit einer abzuzweigenden Leitung auf.Die vorbekannte Abzweigdose ist zu einer Mehrfach-Abzweigdose erweiterbar. Allerdings geht aus DE-A-2 507 130 nicht hervor, wie diese Mehrfach-Abzweigdose aufgebaut ist. Es muß deshalb davon ausgegangen werden, daß mehrere Abzweigbuchsen mit jeweils sich daran anschließenden Gehäusebestandteilen einer Einfach-Abzweigdose in Kabellängsrichtung nebeneinander angeordnet sind. Dadurch wird aber der fertigungstechnische Aufwand und der Raumbedarf der Mehrfach-Abzweigdose weiter erhöht.The known junction box housing also has a junction box for the electrical connection of a ribbon cable effective as a main power line with a line to be branched off. The known junction box is closed expandable with a multiple junction box. However, DE-A-2 507 130 does not show how this multiple junction box is constructed. So it has to go be assumed that several branch sockets each with it subsequent housing components of a single junction box in the longitudinal direction of the cable are arranged side by side. But this is the manufacturing technology The effort and space requirements of the multiple junction box are further increased.

Der Erfindung liegt die Aufgabe zugrunde, die Konstruktion des Gehäuses einer Zweifach-Abzweigdose der eingangs genannten Art zu vereinfachen. Diese Aufgabe wird durch die Merkmalskombination des Anspruches 1 gelöst.The invention has for its object the construction of the housing To simplify double junction box of the type mentioned. This task is solved by the combination of features of claim 1.

Erfindungsgemäß sind die beiden Abzweigbuchsen der Zweifach-Abzweigdose platzsparend aneinandergereiht und verringern dadurch den Raumbedarf des gesamten Abzweigdosengehäuses erheblich. Die kompakte Aneinanderlage der beiden Abzweigbuchsen vermeidet außerdem funktionslose, die mechanische Stabilität beeinträchtigende Luftspalte des Abzweigdosengehäuses. Dies verbessert die mechanische Stabilität des Abzweigdosengehäuses. Die mit ihren Einstecköffnungen voneinander abgewandte Aneinanderreihung der beiden Abzweigbuchsen unter Bildung lediglich einer Teilungsfuge ermöglicht außerdem eine einheitliche und deshalb platzsparende Steckrichtung der mit der Abzweigdose gekoppelten Stecker.According to the two branch sockets of the double junction box lined up in a space-saving manner and thereby reduce the space requirement of the whole Junction box housing considerably. The compact arrangement of the two branch sockets also avoids non-functional, the mechanical Air gaps in the junction box housing impairing stability. This improves the mechanical stability of the junction box housing. The one with its insertion openings Series of the two branch sockets facing away from each other allowing only a dividing line also allows a uniform and therefore space-saving direction of insertion with the junction box coupled connector.

Ein schraubstockartig wirksamer Klammerbügel verklammert gewissermaßen die beiden durch die Teilungsfuge voneinander getrennten Buchsengehäuseteile in Montagestellung miteinander. Ein Auseinanderreißen der beiden Abzweigbuchsen - z.B. beim Herausziehen eines Steckers - wird deshalb wirkungsvoll verhindert. Gleichzeitig ist der Klammerbügel aufgrund seiner U-Form fertigungstechnisch einfach und kostengünstig herstellbar. Die U-Form vereinfacht außerdem seine Montage am Abzweigdosengehäuse.A vise-like clamp bracket clamps the to a certain extent two socket housing parts separated by the parting line in Assembly position with each other. A tearing apart of the two branch sockets - e.g. when pulling out a plug - is therefore effectively prevented. At the same time, due to its U-shape, the clamp bracket is production-related easy and inexpensive to manufacture. The U shape also simplifies its Mounting on the junction box housing.

Das Abzweigdosengehäuse besteht üblicherweise aus einem isolierenden Kunststoff. Als Buchsengehäuseteile können gegebenenfalls auch bereits vorkonfektionierte, auf dem Markt in großer Auswahl vorhandene Buchsengehäuse einer Buchse verwendet werden. Sie müssen dann lediglich an die Anforderungen des erfindungsmäßigen Abzweigdosengehäuses angepaßt werden und hierbei insbesondere für eine Fixierung des Klammerbügels geeignet sein. The junction box housing usually consists of an insulating plastic. If necessary, pre-assembled, A wide range of socket housings available on the market Socket are used. You then only have to meet the requirements of the inventive junction box are adapted and in particular be suitable for fixing the clamp bracket.

Anspruch 2 unterstützt eine für den Monteur einfache und bequeme Montage des Klammerbügels.Claim 2 supports a simple and convenient installation of the Clip bracket.

Gemäß Anspruch 3 greifen die beiden Klammerarme des Klammerbügels in den jeweils zugeordneten Buchsengehäuseteil ein. Die für diesen Eingriff in den Buchsengehäuseteilen vorhandenen Ausnehmungen ermöglichen eine montageerleichternde Vorfixierung des Klammerbügels während dessen Montage. Vorteilhaft greifen die Klammerarme formschlüssig in entsprechende Ausnehmungen der Buchsengehäuseteile ein.According to claim 3, the two clamp arms of the clamp bracket engage in the each assigned socket housing part. The for this engagement in the socket housing parts Existing recesses make assembly easier Pre-fixing the clamp bracket during assembly. Advantageous the clamp arms positively engage in corresponding recesses in the Socket housing parts.

Die Verrastung des Klammerbügels gemäß Anspruch 4 gewährleistet eine einfache Funktionskontrolle, ob sich der Klammerbügel tatsächlich in Montagestellung befindet. Die Lösbarkeit der Verrastung unterstützt die einfache Demontage des Abzweigdosengehäuses, falls einzelne Bestandteile des Abzweigdosengehäuses überprüft oder ausgetauscht werden müssen.The latching of the clip bracket according to claim 4 ensures a simple Functional check whether the clamp bracket is actually in the assembly position located. The releasability of the latching supports the simple disassembly of the Junction box housing, if individual components of the junction box need to be checked or replaced.

Gemäß Anspruch 5 ist der Klammerbügel einstückiger Bestandteil einer isolierenden, vorzugsweise aus Isolierkunststoff hergestellten Abdeckkappe. Die Abdeckkappe wird auf die Buchsengehäuseteile aufgesetzt und deckt dabei die Betätigungsseite der Kontaktelemente ab. Dadurch hat der Klammerbügel bzw. die Abdeckkappe neben der Klammerungsfunktion für die beiden Abzweigbuchsen die zusätzliche Funktion einer mechanischen und elektrischen Abschirmung der Betätigungsseite des Abzweigdosengehäuses nach außen. Insbesondere werden die von der Bestätigungsseite her zugänglichen Kontaktelemente vor mechanischen Beschädigungen oder unerwünschten elektrischen Kontaktierungen geschützt.According to claim 5, the clip bracket is an integral part of an insulating, preferably made of insulating plastic cover. The cover cap is placed on the socket housing parts and covers the actuation side of the contact elements. This has the clip bracket or the cover cap in addition to the bracketing function for the two branch sockets additional function of mechanical and electrical shielding of the actuation side of the junction box housing to the outside. In particular, be the contact elements accessible from the confirmation side before mechanical Damage or unwanted electrical contacts protected.

Die Abzweigkappe verschließt gewissermaßen isolierend die Betätigungsseite des Abzweigdosengehäuses und verhindert dadurch, daß nachträglich an den Kontaktelementen Manipulationen stattfinden können.The junction cap isolates the actuating side of the Junction box housing and thereby prevents retrofitting on the contact elements Manipulations can take place.

Gemäß Anspruch 6 wird die Abdeckkappe an den Buchsengehäuseteilen verrastet und nimmt dadurch eine mechanisch stabile Montagestellung ein.According to claim 6, the cover cap is locked on the socket housing parts and thereby assumes a mechanically stable mounting position.

Anspruch 7 schlägt ein für die elektrische Kontaktierung eines Leitungskabels bewährtes und einfach betätigbares Kontaktelement in Form einer Spitzschraube vor. Sie wird von der Betätigungsseite her etwa rechtwinklig zur Kabelebene in das Abzweigdosengehäuse eingeschraubt. Die vollständig eingeschraubte bzw. festgeschraubte Spitzschraube stellt einen direkten elektrischen Kontakt zwischen der Kontakthülse der Abzweigbuchse und der zugeordneten Kabelader im Leitungskabel bzw. Flachbandkabel her. Dadurch entsteht eine einfache elektrische Kontaktierung zwischen dem Leitungskabel und der abzuzweigenden Leitung. Die herkömmliche Verkabelung der abisolierten Litzen einer abzuzweigenden Leitung mit entsprechenden Klemmschrauben der Abzweigdose und der dadurch verbundene Montageaufwand entfallen. Durch das vollständige Fehlen dieser Verkabelung wird auch eine mögliche Fehlerquelle beim Anschluß der abzuzweigenden Leitung eliminiert.Claim 7 proposes a proven for the electrical contacting of a cable and easily actuated contact element in the form of a pointed screw in front. It is approximately at right angles to the cable level from the actuation side the junction box housing is screwed in. The fully screwed or screwed-in pointed screw provides a direct electrical contact between the contact sleeve of the branch socket and the assigned cable core in the cable or ribbon cable. This creates a simple electrical Contact between the line cable and the line to be branched. The Conventional wiring of the stripped strands of a line to be branched with appropriate clamping screws of the junction box and the connected one Assembly effort is eliminated. Due to the complete absence of this wiring also becomes a possible source of error when connecting the to be branched off Line eliminated.

Gemäß Anspruch 8 hat die Abdeckkappe eine weitere Funktion: Sie dient zur Überprüfung, ob die Spitzschrauben vollständig eingeschraubt und ordnungsgemäß mit den zugeordneten Kabeladern des Leitungskabels elektrisch kontaktiert sind. Zu diesem Zweck ist an der Kappeninnenseite jedem Schraubenkopf einer Spitzschraube zugeordnet ein zapfenartiger Flankiervorsprung angeformt. Dieser Flankiervorsprung flankiert den Schraubenkopf der ordnungsgemäß festgeschraubten Spitzschraube. Auf diese Weise ist gewährleistet, daß die Abdeckkappe nur dann in ihre Sollmontagestellung gelangen kann, wenn sämtliche Spitzschrauben des Abzweigdosengehäuses vollständig eingeschraubt sind, wenn also der elektrische Kontakt zwischen den Abzweigbuchsen und dem Leitungskabel vollständig hergestellt ist. Die Abdeckkappe hat deshalb die Funktion einer Prüfvorrichtung zur Überprüfung der erfolgten elektrischen Kontaktierung zwischen Kontakthülse und der zugeordneten Kabelader des Leitungskabels.According to claim 8, the cap has another function: it is used for Check that the pointed screws are fully screwed in and properly electrically contacted with the assigned cable wires of the cable are. For this purpose, there is one screw head on the inside of the cap Pointed screw assigned to a peg-like flanking projection. This Flanking projection flanks the screw head of the properly screwed Pointed screw. This ensures that the cover cap can only reach its target assembly position if all the pointed screws of the junction box housing are fully screwed in, if so the electrical contact between the branch sockets and the cable is completely manufactured. The cover cap therefore has the function of a test device to check the electrical contact between Contact sleeve and the assigned cable core of the cable.

Anspruch 9 schlägt eine Maßnahme zur vereinfachten Montage und Betätigung der Spitzschrauben vor. Der Schraubenkopf der Spitzschraube befindet sich in einem zur Betätigungsseite hin offenen Führungstrichter des Buchsengehäuses. Dieser Führungstrichter führt einerseits den Schraubenkopf beim Einschrauben und dient andererseits als Betätigungsführung für die Klinge des zum Einschrauben der jeweiligen Spitzschraube verwendeten Schraubendrehers.Claim 9 proposes a measure for simplified assembly and operation the pointed screws. The screw head of the pointed screw is in a guide funnel of the socket housing which is open towards the actuation side. On the one hand, this guide funnel guides the screw head when screwing in and on the other hand serves as an actuation guide for the blade to screw in the respective screwdriver used.

Die Ansprüche 11 und 12 unterstützen die einfache Montage der Abdeckkappe. Gemäß Anspruch 11 wird der Verfahrweg der Abdeckkappe beim Aufsetzen auf das Abzweigdosengehäuse begrenzt. Die formschlüssig in die zugeordneten Führungstrichter eingreifenden Flankiervorsprünge gemäß Anspruch 12 ermöglichen eine Bewegungsführung der Abdeckkappe während des Aufsetzvorganges. Claims 11 and 12 support the simple assembly of the cover cap. According to claim 11, the path of the cover cap when put on the junction box housing is limited. The form-fitting in the assigned guide funnels enable engaging flanking projections according to claim 12 a movement of the cap during the placement process.

Führungstrichter, in die keine Spitzschraube eingesetzt werden soll, können durch geeignete Mittel nach außen verschlossen oder durch anderweitige Mittel gekennzeichnet sein. Dadurch werden unerwünschte Kontaktierungen zwischen bestimmten Buchsenpolen und bestimmten Kabeladern des Leitungskabels zuverlässig verhindert.Guide funnels, in which no pointed screw should be inserted, can by suitable means locked to the outside or marked by other means his. This eliminates unwanted contacts between certain Socket poles and certain cable cores of the cable are reliable prevented.

Anspruch 13 unterstützt die Klammerfunktion des Klammerbügels bzw. der Abdeckkappe. Hierzu schlägt Anspruch 13 einen im wesentlichen in Steckrichtung verlaufenden Federhaken vor. Dieser Federhaken durchsetzt den zugeordneten Buchsengehäuseteil und ist mit einem Rastende unverlierbar nach Art eines Widerhakens im zweiten Buchsengehäuseteil gelagert. Diese Widerlagerung des Federhakens an dem zweiten Buchsengehäuseteil bewirkt, daß beim Auftreten von Zugbelastungen in Steckrichtung der das Befestigungsende des Federhakens widerlagernde zweite Buchsengehäuseteil an den ersten Buchsengehäuseteil geradezu herangedrückt wird. Auf diese Weise wird ein Zerreißen des Abzweigdosengehäuses in Steckrichtung verhindert. Das dem Befestigungsende in Steckrichtung gegenüberliegende Rastende des Federhakens dient in bekannter Weise als Verriegelung zwischen der Abzweigbuchse und dem zugeordneten Stecker. Vorzugsweise enthalten beide Buchsengehäuseteile jeweils einen identischen Federhaken gemäß Anspruch 13.Claim 13 supports the clip function of the clip bracket or the cover cap. For this purpose, claim 13 proposes a substantially in the direction of insertion running spring hook. This spring hook passes through the assigned Socket housing part and with a latching end is captive in the manner of a barb stored in the second socket housing part. This abutment of the Spring hook on the second socket housing part causes it to occur of tensile loads in the direction of insertion of the fastening end of the spring hook abutting second socket housing part to the first socket housing part downright is pressed. In this way, the junction box housing is torn prevented in the direction of insertion. That the fastening end in the direction of insertion opposite locking end of the spring hook is used in a known manner as a lock between the branch socket and the assigned plug. The two socket housing parts preferably each contain an identical one Spring hook according to claim 13.

Gemäß Anspruch 15 durchsetzt die Kontakthülse beide Buchsengehäuseteile des Abzweigdosengehäuses und trägt deshalb nach Art eines Bewehrungsstabes dazu bei, daß die Bestandteile des Abzweigdosengehäuses auch bei äußeren Krafteinwirkungen eine mechanisch stabile Einheit bilden. Außerdem wirkt die in den ersten Buchsengehäuseteil eingesetzte Kontakthülse als Fixierhilfe bei der Montage des zweiten Buchsengehäuseteiles. Weiterhin vereinfacht diese Kontakthülse die Bereitstellung der Pole der Zweifach-Abzweigdose.According to claim 15, the contact sleeve penetrates both socket housing parts of the Junction box housing and therefore contributes to it in the manner of a reinforcing bar in that the components of the junction box housing also with external Force effects form a mechanically stable unit. In addition, the in the first socket housing part used contact sleeve as a fixing aid in the Assembly of the second socket housing part. This contact sleeve also simplifies the provision of the poles of the double junction box.

Die Ansprüche 16 und 17 berücksichtigen die fertigungstechnisch einfache Herstellung der Kontakthülse. Aufgrund ihrer symmetrischen Ausgestaltung werden Fehlmontagen der Kontakthülse vermieden.Claims 16 and 17 take into account the simple manufacture the contact sleeve. Because of their symmetrical design Incorrect assembly of the contact sleeve avoided.

Die Ansprüche 18 und 19 unterstützen die platzsparende Anordnung der Abzweigbuchsen und folglich auch der gesamten Abzweigdose relativ zum Leitungskabel. Der gemäß Anspruch 21 von der Kontakthülse etwa radial abstehende Kontaktlappen bewirkt eine Querverschiebung des Gewindes für die Spitzschraube. Durch entsprechende radiale Überstände der Kontaktlappen ist eine elektrische Kontaktierung der Kabeladern mit den zugeordneten Spitzschrauben unabhängig vom Abstand zweier benachbarter Kontakthülsen realisierbar. Auf diese Weise ist eine einfache Anpassung des Abstandsrasters der Kabeladern eines Flachbandkabels an das Abstandsraster der Kontakthülsen einer Abzweigbuchse möglich.Claims 18 and 19 support the space-saving arrangement of the branch sockets and consequently the entire junction box relative to the cable. The contact tab projecting approximately radially from the contact sleeve causes a transverse displacement of the thread for the pointed screw. Due to the corresponding radial projections of the contact tabs, an electrical one Contacting of the cable wires with the assigned pointed screws independently realizable from the distance between two adjacent contact sleeves. That way a simple adjustment of the spacing of the cable cores of a ribbon cable possible to the spacing of the contact sleeves of a branch socket.

Ist der Kontaktlappen gemäß Anspruch 21 an einer symmetrischen Kontakthülse gemäß Anspruch 16 und/oder 17 angeformt, kann derselbe Kontakthülsentyp sowohl für die Links- als auch für die Rechtsmontage in einen Buchsengehäuseteil eingesetzt werden, da dieser Kontakthülsentyp für seine erforderliche Einbaulage gewissermaßen mehrere Freiheitsgrade besitzt. Die Kontakthülse kann sowohl um ihre in Steckrichtung verlaufenden Mittellängsachse zur Links- bzw. Rechtsmontage um 180° rotiert werden als auch bezüglich der Steckrichtung um 180° verdreht werden. Selbstverständlich sind diese Freiheitsgrade der Kontakthülse auch ohne den Kontaktlappen gegeben.Is the contact tab according to claim 21 on a symmetrical contact sleeve molded according to claim 16 and / or 17, the same type of contact sleeve can both for the left as well as for the right assembly in a socket housing part can be used as this type of contact sleeve for its required installation position has several degrees of freedom, so to speak. The contact sleeve can both around its central longitudinal axis running in the direction of insertion for left or right mounting are rotated by 180 ° as well as 180 ° with regard to the direction of insertion be twisted. Of course, these degrees of freedom of the contact sleeve also given without the contact tab.

Gemäß den Ansprüchen 22 und 23 kann die Kontakthülse wahlweise mit verschiedenen Kabeladern des Flachbandkabels elektrisch kontaktiert werden. Vorzugsweise weist die Kontakthülse eine der Anzahl der Kabeladern im Flachbandkabel entsprechende Anzahl von Gewinden auf. Auf diese Weise ist es möglich, die Kontakthülse mit jeder Kabelader des Flachbandkabels elektrisch zu kontaktieren. Eine entsprechende Anzahl von Kontakthülsen vorausgesetzt, können also von Flachbandkabeln mit beliebigen Aderkonfigurationen beliebige Buchsenkonfigurationen abgeleitet werden. Liegen die Adern im Flachbandkabel in einer anderen Reihenfolge nebeneinander als es die Reihenfolge der Pole eines vorkonfektionierten Buchsen-Stecker-Systems erfordert, ist die Konfiguration der Abzweigbuchse an den erwünschten Sollzustand mit Hilfe der Kontakthülsen gemäß den Ansprüchen 22 und 23 problemlos anpaßbar.According to claims 22 and 23, the contact sleeve can optionally with different Cable cores of the ribbon cable are electrically contacted. Preferably the contact sleeve has one of the number of cable wires in the ribbon cable corresponding number of threads. In this way it is possible to electrically contact the contact sleeve with each cable core of the ribbon cable. Assuming a corresponding number of contact sleeves, you can of ribbon cables with any wire configurations, any socket configurations be derived. Are the wires in the ribbon cable in another Order side by side as it is the order of the poles of a pre-assembled Socket plug system requires the configuration of the branch socket to the desired target state using the contact sleeves according to the Claims 22 and 23 easily adaptable.

Um eine unerwünschte elektrische Kontaktierung bestimmter Kontakthülsen mit bestimmten Kabeladern auszuschließen, wird das die Kontakthülsen umgebende Buchsengehäuse zweckmäßig derart ausgestaltet, daß das Buchsengehäuse nur diejenigen Gewinde frei läßt, in denen auch tatsächlich eine Spitzschraube eingeschraubt werden soll. Die übrigen Gehäuse sind dann durch das Buchsengehäuse inaktiviert.To avoid undesired electrical contacting of certain contact sleeves to exclude certain cable cores, that which surrounds the contact sleeves Socket housing expediently designed such that the socket housing only leaves those threads free, in which a pointed screw is actually screwed shall be. The remaining housings are then through the socket housing deactivated.

Das vorbeschriebene Prinzip der Ableitung einer beliebigen Buchsenkonfiguration von einem Flachbandkabel mit beliebiger Aderkonfiguration und beliebiger Aderanzahl ist selbstverständlich nicht auf eine Abzweigdose mit zwei Abzweigbuchsen beschränkt. Dieses Prinzip läßt sich analog auf Kontakthülsen übertragen, die lediglich einer einzigen Abzweigbuchse zugeordnet sind.The above-described principle of deriving any socket configuration of a ribbon cable with any wire configuration and any number of wires is of course not on a junction box with two branch sockets limited. This principle can be applied analogously to contact sleeves that are only assigned to a single branch socket.

Unabhängig von einer Ausgestaltung der Abzweigdose gemäß den Merkmalen der Ansprüche 1 - 23 ist die Konstruktion und Montage des Gehäuses einer Abzweigdose für ein Leitungskabel dadurch vereinfacht, daß eine an der Gehäuseunterseite des Abzweigdosengehäuses lösbar befestigte, den Kabelmantel des Leitungskabels umfassende Bodenschale quer zur Kabellängsrichtung von einer Gehäuseseitenwand her in ihre Montagestellung einschiebbar ist. Dadurch entsteht ein im Vergleich zum Stand der Technik kurzer Verschiebeweg, der z.B. wenige, insbesondere 3, mm beträgt. Dies begünstigt die Montage des Abzweigdosengehäuses gemäß Anspruch 24 in einem engen Kabelkanal bzw. Kabelschacht.Regardless of a design of the junction box according to the features of claims 1-23 is the construction and assembly of the housing of a junction box simplified for a cable that one on the underside of the housing of the junction box detachably attached, the cable jacket of Ground cable comprehensive bottom shell transverse to the longitudinal direction of one Housing side wall can be inserted into its mounting position. This creates a short displacement path compared to the prior art, e.g. few, in particular 3, mm. This favors the assembly of the junction box housing according to claim 24 in a narrow cable duct or cable duct.

Die L-förmige Gehäuseunterseite des Abzweigdosengehäuses gemäß Anspruch 25 schafft eine gute Bewegungsführung und eine Verschiebebegrenzung für die Bodenschale während ihrer Montage.The L-shaped housing underside of the junction box housing according to claim 25 creates good movement control and a movement limitation for the bottom shell during assembly.

Anspruch 26 verhindert ein fehlerhaftes Einlegen des Leitungskabels, insbesondere des Flachbandkabels in die Bodenschale.Claim 26 prevents incorrect insertion of the cable, in particular the ribbon cable into the bottom shell.

Gemäß Anspruch 27 bilden die Bodenschale und das Leitungskabel eine kompakte und deshalb mechanisch stabile Einheit, die schließlich mit dem übrigen Abzweigdosengehäuse verbunden wird.According to claim 27, the bottom shell and the cable form a compact and therefore mechanically stable unit, which eventually with the rest of the junction box is connected.

Gemäß Anspruch 28 ist das Leitungskabel von der U-förmigen Bodenschale von vornherein an drei Kabelseiten flankiert. Auf diese Weise bildet die Bodenschale eine verbesserte Fixierhilfe beim Einlegen des Leitungskabels.According to claim 28, the cable from the U-shaped bottom shell of flanked in advance on three cable sides. In this way, the bottom shell forms an improved fixing aid when inserting the cable.

Anspruch 29 unterstützt einen mechanisch stabilen Montagezustand der Bodenschale. Die Schenkelfreienden der U-förmigen Bodenschale sind als Vorsprünge ausgebildet. Diese Vorsprünge greifen in komplementär ausgebildete Ausnehmungen oder Nuten des Abzweigdosengehäuses ein und sichern dadurch die Bodenschale in ihrer Montagestellung. Außerdem können noch weitere Hinterhakteile oder Durchgriffteile an der Bodenschale oder am übrigen Abzweigdosengehäuse als zusätzliche Sicherung der Bodenschale vorgesehen sein.Claim 29 supports a mechanically stable installation state of the base shell. The leg-free ends of the U-shaped base shell are as projections educated. These projections engage in complementary recesses or grooves of the junction box housing and thereby secure the Floor pan in its assembly position. In addition, other rear hook parts can or penetration parts on the base shell or on the other junction box housing be provided as an additional securing of the bottom shell.

Die in Fig. 1 dargestellte Zweifach-Abzweigdose 1 für ein Flachbandkabel 2 enthält zwei Abzweigbuchsen 3,4 für jeweils einen in Fig. 1 nicht dargestellten Stekker einer abzuzweigenden Leitung. Weiterhin enthält die Abzweigdose 1 mehrere Kontaktelemente in Form von Spitzschrauben 5 zur elektrischen Kontaktierung einer Kabelader 6 des Flachbandkabels 2. Die Spitzschraube 5 sitzt im Abzweigdosengehäuse ein und wirkt mit einer einen Pol der Abzweigbuchse 3 und 4 bildenden metallischen Kontakthülse 7 zusammen. Mittels der Spitzschraube 5 wird die Kontakthülse 7 mit der Kabelader 6 elektrisch kontaktiert. Die beiden Abzweigbuchsen 3,4 sind in Steckrichtung 8 mit ihren Einstecköffnungen 9,10 für die Stecker voneinander abgewandt aneinandergereiht unter Bildung einer Teilungsfuge 11. Ein im Querschnitt U-förmiger Klammerbügel 12 enthält zwei in Steckrichtung 8 gegenüberliegende, die U-Schenkel bildenden Klammerarme 13. In der in Fig. 1 dargestellten Montagestellung halten die beiden Klammerarme 13 die beiden Buchsengehäuseteile 14,15 in schraubstockartig dichter Anlage aneinander. Die Klammerarme 13 stehen in Richtung der Kabelebene des Flachbandkabels 2 vor. In dieser Richtung ist der Klammerbügel 12 auf die beiden Buchsengehäuseteile 14,15 aufsetzbar. In der Montagestellung greifen die beiden Klammerarme 13 in jeweils einen Buchsengehäuseteil 14,15 etwa formschlüssig ein. Der Klammerbügel 12 ist einstückiger Bestandteil einer Abdeckkappe 16 mit quer zur Steckrichtung 8 verlaufenden Kappenseitenwänden als Klammerarme 13. Die Abdeckkappe 16 ist von der Betätigungsseite 17 der Spitzschraube 5 her auf die Buchsengehäuseteile 14,15 aufsetzbar und isoliert die gesamte Betätigunsseite 17, insbesondere die Spitzschraube 5 nach außen. Die beiden Klammerarme 13 der Abdeckkappe 16 erstrecken sich vorzugsweise etwa über die gesamte Breite der Buchsengehäuseteile 14,15. Die Abdeckkappe 16 weist zwei weitere, in Steckrichtung 8 parallel verlaufende Kappenseitenwände 18 auf (Fig. 2). Die Abdeckkappe 16 ist in ihrer in Fig. 2 dargestellten Montagestellung mit den Buchsengehäuseteilen 14,15 verrastet. Zu diesem Zweck sind die in Richtung des Flachbandkabels vorstehenden Freienden der Kappenseitenwände 18 als Federhaken 19 ausgebildet, welche entsprechende Ausnehmungen der Buchsengehäuseteile 14,15 hintergreifen. Auf diese Weise ist die Abdeckkappe 16 lösbar verrastet.The double junction box 1 shown in Fig. 1 for a ribbon cable 2 contains two branch sockets 3, 4 each for a plug not shown in FIG. 1 a line to be branched off. The junction box 1 also contains several Contact elements in the form of pointed screws 5 for electrical contacting a cable core 6 of the ribbon cable 2. The pointed screw 5 is located in the junction box housing and acts with one pole of the branch socket 3 and 4 forming metallic contact sleeve 7 together. Using the pointed screw 5 the contact sleeve 7 is electrically contacted with the cable core 6. The two branch sockets 3,4 are in the insertion direction 8 with their insertion openings 9,10 for the Plugs facing away from each other, forming a division joint 11. A U-shaped clip bracket 12 contains two in the direction of insertion 8 opposite clamp arms forming the U-legs 13. In the in Fig. 1 shown mounting position, the two bracket arms 13 hold the two Socket housing parts 14, 15 close together in a vice-like manner. The clamp arms 13 stand in the direction of the cable level of the ribbon cable 2 in front. In this direction the clamp bracket 12 is on the two socket housing parts 14.15 can be put on. In the assembly position, the two clamp arms 13 grip in a respective socket housing part 14, 15 approximately form-fitting. The clamp bracket 12 is an integral part of a cover cap 16 with transverse to the direction of insertion 8 running cap side walls as clamp arms 13. The cover cap 16 is from the actuating side 17 of the pointed screw 5 on the socket housing parts 14, 15 can be put on and insulates the entire actuation side 17, especially the pointed screw 5 to the outside. The two bracket arms 13 of the Cover cap 16 preferably extend approximately over the entire width of the Socket housing parts 14.15. The cover cap 16 has two more, in the direction of insertion 8 parallel cap side walls 18 on (Fig. 2). The cover cap 16 is in its mounting position shown in Fig. 2 with the socket housing parts 14.15 locked. For this purpose they are in the direction of the ribbon cable protruding free ends of the cap side walls 18 are designed as spring hooks 19, which engage behind corresponding recesses in the socket housing parts 14, 15. In this way, the cap 16 is releasably locked.

Die Spitzschrauben 5 werden von der Betätigungsseite 17 her rechtwinklig zur Kabelebene des Flachbandkabels 2 in Einschraubrichtung 20 soweit eingeschraubt, daß die Spitzschrauben 5 sowohl den Kabelmantel 21 des Flachbandkabels als auch die Aderisolierung 22 der Kabelader 6 durchschneidet und mit ihrer Schraubenspitze in den metallischen Werkstoff der Kabelader 6 eindringt. Die Spitzschraube 5 ist in ein mit der Kontakthülse 7 mechanisch und elektrisch verbundenes Gewinde 23 eingeschraubt. Sobald die Spitzschraube 5 in die Kabelader 6 eindringt, entsteht automatisch der erwünschte elektrische Kontakt zwischen der Kontakthülse 7 und der zugeordneten Kabelader 6. The pointed screws 5 are at right angles to the actuation side 17 Cable level of the ribbon cable 2 screwed in in the screwing direction 20 as far as that the pointed screws 5 both the cable sheath 21 of the ribbon cable and also the wire insulation 22 of the cable wire 6 cuts through and with it Screw tip penetrates into the metallic material of the cable core 6. The The pointed screw 5 is mechanically and electrically connected to the contact sleeve 7 Thread 23 screwed in. As soon as the pointed screw 5 in the cable core 6 penetrates, the desired electrical contact between the contact sleeve 7 and the associated cable core 6.

An der Kappeninnenseite der Abdeckkappe 16 sind mehrere zapfenartige, zylindrisch ausgestaltete Flankiervorsprünge 24 angeformt. Jeweils ein Flankiervorsprung 24 ist einer Spitzschraube 5 zugeordnet. In der in Fig. 1 und Fig. 2 dargestellten Sollmontagestellung der Abdeckkappe 16 flankiert der Flankiervorsprung 24 den Schraubenkopf 25 der Spitzschraube 5. Hierbei greift der Flankiervorsprung 24 formschlüssig in einen am Buchsengehäuseteil 14 oder 15 angeformten und zur Betätigungsseite 17 hin offenen Führungstrichter 26 ein und füllt den gesamten Hohlraum des Führungstrichters 26 oberhalb des Schraubenkopfes 25 aus. Der Flankiervorsprung 24 hat eine derartige Aufbauhöhe, daß er beim Versuch einer Montage der Abdeckkappe 16 auf dem Schraubenkopf 25 aufsitzt, wenn die Spitzschraube 5 nicht ordnungsgemäß eingeschraubt ist. In diesem Fall blockieren also die Flankiervorsprünge 24 die ordnungsgemäße Montage der Abdeckkappe 16. Die Abdeckkappe 16 mit ihren Flankiervorsprüngen 24 ermöglicht deshalb eine einfache Funktionskontrolle, ob die einzelnen Kabeladern 6 mit den zugeordneten Kontakthülsen 7 ordnungsgemäß kontaktiert sind.On the inside of the cap of the cap 16 are a plurality of cone-like, cylindrical designed flanking projections 24 are formed. One flanking projection each 24 is assigned to a pointed screw 5. In the shown in Fig. 1 and Fig. 2 The desired mounting position of the cover cap 16 flanks the flanking projection 24 the screw head 25 of the pointed screw 5. The flanking projection engages 24 in a form-fitting manner in one of the socket housing part 14 or 15 and towards the actuation side 17 open guide funnel 26 and fills the entire cavity of the guide funnel 26 above the screw head 25 out. The flanking projection 24 has such a height that it at Attempt to mount the cover cap 16 on the screw head 25, if the pointed screw 5 is not screwed in properly. In this case So the flanking projections 24 block the correct assembly of the cover cap 16. The cover cap 16 with its flanking projections 24 enables therefore a simple function check whether the individual cable wires 6 with the assigned contact sleeves 7 are properly contacted.

In einer Ausführungsform hat der Führungstrichter 26 eine derartige Aufbauhöhe, daß dessen der Betätigungsseite 17 zugewandter Trichterrand 27 die Kappeninnenseite der Abdeckkappe 16 in Sollmontagestellung abstützt (Fig. 1). Dies stabilisiert die Abdeckkappe 16 in ihrer Sollmontagestellung zusätzlich.In one embodiment, the guide funnel 26 has such a height that that the funnel edge 27 facing the actuating side 17 the inside of the cap the cap 16 supports in the target mounting position (Fig. 1). This stabilizes the cap 16 in its target mounting position additionally.

Die beiden Buchsengehäuseteile 14,15 weisen jeweils einen in Steckrichtung 8 verlaufenden Federhaken 28 auf. Der Federhaken 28 enthält zwei in Steckrichtung 8 einander gegenüberliegende Freienden. Das den eigentlichen Federhaken bildende Rastende 29 dient der lösbaren Verrastung mit dem Steckergehäuse eines Steckers. Das dem Rastende gegenüberliegende und in den Figuren nicht sichtbare Befestigungsende des Federhakens 28 ist im jeweils anderen Buchsengehäuseteil 14,15 nach Art eines Widerhakens unverlierbar gelagert. Auf diese Weise wird ein Auseinanderreißen der beiden Buchsengehäuseteile 14,15 aus ihrer Sollmontagestellung verhindert. Der Federhaken 28 ist U-förmig mit parallel zur Kabelebene des Flachbandkabels 2 verlaufender U-Ebene, wobei das U-Querjoch das Rastende 29 bildet und die Freienden der U-Schenkel das nicht sichtbare Befestigungsende bilden.The two socket housing parts 14, 15 each have one in the plug-in direction 8 extending spring hook 28 on. The spring hook 28 contains two in the direction of insertion 8 opposing freeers. That is the actual spring hook Forming locking end 29 is used for releasable locking with the connector housing Connector. The one opposite the latching end and not in the figures visible fastening end of the spring hook 28 is in the other socket housing part 14,15 captive in the manner of a barb. To this The two socket housing parts 14, 15 are torn apart their target mounting position prevented. The spring hook 28 is U-shaped with parallel to the cable level of the ribbon cable 2 running U-plane, the U-transverse yoke the locking end 29 forms and the free ends of the U-legs do not form visible attachment ends.

Die Kontakthülse 7 ist als gleicher Pol für beide Abzweigbuchsen 3,4 wirksam und durchsetzt zu diesem Zweck die beiden Buchsengehäuseteile 14,15 in Steckrichtung 8. Bei der Montage der Buchsengehäuseteile 14,15 wird die Kontakthülse 7 z.B. erst in den in Fig. 1 linken Buchsengehäuseteil 14 eingesetzt und anschließend wird der zweite Buchsengehäuseteil 15 dem ersten Buchsengehäuseteil 14 hinzugefügt und so zum Gesamtgehäuse der Abzweigbuchsen 3,4 ergänzt. In Montagestellung ist die Kontakthülse 7 spiegelsymmetrisch bezüglich einer entlang der Teilungsfuge 11 und parallel zur Einschraubrichtung 20 verlaufenden Symmetrieachse (Fig. 1). Außerdem ist die Kontakthülse 7 rotationssymmetrisch bezüglich ihrer in Steckrichtung 8 verlaufenden Mittellängsachse 30 ausgebildet.The contact sleeve 7 is effective as the same pole for both branch sockets 3, 4 and for this purpose penetrates the two socket housing parts 14, 15 in the plug-in direction 8. When assembling the socket housing parts 14, 15, the contact sleeve 7 e.g. first inserted into the socket housing part 14 on the left in FIG. 1 and then the second socket housing part 15 becomes the first socket housing part 14 added and thus added to the overall housing of the branch sockets 3.4. In In the mounting position, the contact sleeve 7 is mirror-symmetrical with respect to one the parting line 11 and extending parallel to the screwing direction 20 Axis of symmetry (Fig. 1). In addition, the contact sleeve 7 is rotationally symmetrical with respect to their central longitudinal axis 30 extending in the direction of insertion 8.

Die Kontakthülsen 7 derselben Abzweigbuchse 3 oder 4 liegen platzsparend in einer einzigen Ebene ein, wobei die Kontakthülsenebene parallel zur Kabelebene des Flachbandkabels 2 verläuft. An der Kontakthülse 7 können zwei Gewinde 23 (Fig. 1), drei Gewinde 23 (Fig. 4), fünf Gewinde 23 (Fig. 5) oder eine andere Anzahl von Gewinden 23 für jeweils eine Spitzschraube 5 angeordnet sein. In einer Ausführungsform ist an der Kontakthülse 7 ein von der Kontakthülse 7 etwa radial abstehender Kontaktlappen 31 einstückig angeformt. Der Kontaktlappen 31 enthält die Gewinde 23 für die Spitzschrauben 5. Auf diese Weise werden die Gewinde 23 gegenüber der Kontakthülse 7 seitlich versetzt (Fig. 2-4) und fluchten in Einschraubrichtung 20 mit der zugeordneten Kabelader 6 (Fig. 2). Die Kontaktlappen 31 ermöglichen also eine Anpassung unterschiedlicher Abstände zwischen benachbarten Kontakthülsen 7 einerseits und Kabeladern 6 andererseits und vereinfachen dadurch die Konstruktion des Abzweigdosengehäuses zusätzlich.The contact sleeves 7 of the same branch socket 3 or 4 are located in a space-saving manner a single level, the contact sleeve level parallel to the cable level of the ribbon cable 2 runs. On the contact sleeve 7, two threads 23 (Fig. 1), three threads 23 (Fig. 4), five threads 23 (Fig. 5) or another number of threads 23 for one pointed screw 5 each. In a Embodiment is on the contact sleeve 7 from the contact sleeve 7 approximately radial protruding contact tab 31 integrally formed. The contact tab 31 contains the threads 23 for the pointed screws 5. In this way, the threads 23 laterally offset with respect to the contact sleeve 7 (FIGS. 2-4) and aligned Screw-in direction 20 with the assigned cable core 6 (Fig. 2). The contact tabs 31 thus allow an adaptation of different distances between adjacent contact sleeves 7 on the one hand and cable cores 6 on the other hand and thereby additionally simplify the construction of the junction box housing.

Ist die Kontakthülse 7 wie vorbeschrieben symmetrisch ausgebildet und enthält den Kontaktlappen 31, so ist derselbe Kontakthülsentyp sowohl für die Links- als auch für die Rechtsmontage im Buchsengehäuse einsetzbar (Fig. 1, 2). In Fig. 2 ist weiterhin erkennbar, daß die mittlere Kontakthülse 7 der nebeneinandergereihten drei Kontakthülsen 7 keinen seitlichen Kontaktlappen 31 aufweist. Vielmehr ist diese mittlere Kontakthülse 7 selbst radial in Einschraubrichtung 20 von einem Gewinde 23 oder mehreren Gewinden 23 durchsetzt.Is the contact sleeve 7 symmetrical as described above and contains the contact tab 31, is the same type of contact sleeve for both the left and can also be used for right-hand mounting in the socket housing (Fig. 1, 2). In Fig. 2 it can also be seen that the middle contact sleeve 7 of the lined up three contact sleeves 7 has no lateral contact tab 31. Rather is this middle contact sleeve 7 itself radially in the screwing direction 20 from one Thread 23 or more threads 23 passes through.

In Fig. 4 und Fig. 5 verläuft die Steckrichtung 8 rechtwinklig zur Kabellängsrichtung 32. In diesem Fall ist eine Zuordnung einzelner Kontakthülsen 7 zu den Kabeladern 6 des Flachbandkabels 2 beliebig wählbar, wenn der Abstand zwischen zwei benachbarten Gewinden 23 derselben Kontakthülse 7 und der Abstand zweier benachbarter Kabeladern 6 gleichgroß sind und die Kontakthülse 7 eine Anzahl von Gewinden 23 enthält, die mindestens so groß ist wie die Anzahl der Kabeladern 6. Dies sei beispielhaft anhand eines fünfadrigen Flachbandkabels 2 gemäß Fig. 5 erläutert: Zwei Phasenleiter 61,62, ein Schutzerdungsleiter 63, ein Nulleiter 64 und ein Steuerleiter 65 bilden die fünf Kabeladern 6. Diesen fünf Kabeladern 6 sind fünf Kontakthülsen 71-75 mit jeweils fünf Gewinden 23 zugeordnet. Dadurch weist jede Kontakthülse 71,72,73,74,75 eine Kontaktstelle für jeden Leiter 61,62,63,64,65 auf. Sämtliche Kontakthülsen 71-75 können also mit sämtlichen Kabeladern 61-65 elektrisch leitend verbunden werden. In Fig. 5 sind die nicht mit Spitzschrauben 5 belegten Gewinde 23 als weiße Kreise dargestellt. Die jeweils mit einer Spitzschraube 5 belegten Gewinde 23 sind als schwarze Kreise sichtbar. So ist beispielsweise der Schutzerdungsleiter 63 mittels der Spitzschraube 53 mit der Schutzerdungskontakthülse 73 elektrisch kontaktiert. Die in Fig. 5 links außen angeordnete Kontakthülse 74 ist mit dem Nulleiter 64 elektrisch kontaktiert und bildet deshalb die Nulleiterkontakthülse 74. Dieses Beispiel zeigt, daß die Zuordnung der einzelnen Kontakthülsen 71-75 zu den Leitern 61-65 völlig frei wählbar ist. Dieses Prinzip der frei wählbaren Zuordnung ist selbstverständlich auch auf Abzweigdosen mit nicht als Spitzschrauben 5 ausgebildeten Kontaktelementen anwendbar. 4 and 5, the plug-in direction 8 runs at right angles to the longitudinal direction of the cable 32. In this case there is an assignment of individual contact sleeves 7 to the cable cores 6 of the ribbon cable 2 arbitrarily selectable if the distance between two adjacent threads 23 of the same contact sleeve 7 and the distance two adjacent cable cores 6 are the same size and the contact sleeve 7 one Number of threads 23 contains at least as large as the number of Cable cores 6. This is exemplified by a five-core ribbon cable 2 5: Two phase conductors 61, 62, one protective grounding conductor 63, one Neutral conductor 64 and a control conductor 65 form the five cable cores 6. These five cable cores 6, five contact sleeves 71-75, each with five threads 23, are assigned. As a result, each contact sleeve 71, 72, 73, 74, 75 has a contact point for each Ladder 61,62,63,64,65. All contact sleeves 71-75 can therefore with all Cable cores 61-65 are electrically connected. 5 are the thread 23 not shown with pointed screws 5 shown as white circles. The each with a pointed screw 5 threads 23 are as black circles visible. For example, the protective earth conductor 63 is by means of the pointed screw 53 electrically contacted with the protective ground contact sleeve 73. 5 Contact sleeve 74 arranged on the left outside is electrically contacted with neutral conductor 64 and therefore forms the neutral contact sleeve 74. This example shows that the assignment of the individual contact sleeves 71-75 to the conductors 61-65 is completely free is selectable. This principle of freely selectable assignment is a matter of course also on junction boxes with contact elements not designed as pointed screws 5 applicable.

Die vorgenannten Ausführungen gelten analog für das Ausführungsbeispiel einer Abzweigdose 1 mit dreipoligen Abzweigbuchsen 3,4 und einem dreiadrigen Flachbandkabel 2 gemäß Fig. 4.The above statements apply analogously to the embodiment of a Junction box 1 with three-pin branch sockets 3,4 and a three-wire Ribbon cable 2 according to FIG. 4.

Unabhängig von den vorbeschriebenen Merkmalen der erfindungsmäßigen Abzweigdose 1 ist dessen Gehäuse dadurch vereinfacht, daß eine den Kabelmantel 21 des Flachbandkabels 2 quer zur Kabellängsrichtung 32 umfassende Bodenschale 33 von einer Gehäuseseitenwand 34 des Abzweigdosengehäuses her in ihre Montagestellung einschiebbar ist (Fig. 2). Hierbei ist die Bodenschale 33 an einer Gehäuseunterseite 35 des Abzweigdosengehäuses lösbar befestigt. Die Gehäuseunterseite 35 ist im Querschnitt L-förmig mit einem in Querrichtung 36 verlaufenden Gehäuseboden 37 als erstem L-Schenkel und mit einer über den Gehäuseboden 37 hinausstehenden, den Verschiebeweg der Bodenschale 33 begrenzenden Randleiste 38 als zweitem L-Schenkel.Regardless of the features of the junction box according to the invention described above 1, the housing is simplified in that the cable sheath 21 of the ribbon cable 2 transverse to the longitudinal direction 32 comprehensive bottom shell 33 from a housing side wall 34 of the junction box housing can be inserted into its mounting position (Fig. 2). Here, the bottom shell 33 is on a housing underside 35 releasably attached to the junction box housing. The The underside of the housing 35 is L-shaped in cross section with a in the transverse direction 36 extending housing base 37 as the first L-leg and with one over the Protruding housing bottom 37, the displacement of the bottom shell 33 limiting edge strip 38 as a second L-leg.

Die Bodenschale 33 enhält eine etwa in Kabellängsrichtung 32 verlaufende Kodierungsleiste 39. Sie ist komplementär zu einer Kodierungsrille 40 des Kabelmantels 21 ausgebildet. Der Kabelmantel 21 weist zwei in Einschraubrichtung 20 gegenüberliegende Kodierungsrillen 40 auf.The bottom shell 33 contains a coding strip running approximately in the longitudinal direction 32 of the cable 39. It is complementary to a coding groove 40 of the cable jacket 21 trained. The cable sheath 21 has two opposite in the screwing direction 20 Coding grooves 40 on.

Die Bodenschale 33 umfaßt den darin eingelegten Kabelmantel 21 des Flachbandkabels 2 formschlüssig. Die Bodenschale 33 ist im Querschnitt U-förmig mit in Querrichtung 36 verlaufendendem U-Querjoch. An diesem U-Querjoch ist die Kodierungsleiste 39 einstückig angeformt.The bottom shell 33 comprises the cable sheath 21 of the ribbon cable inserted therein 2 positive. The bottom shell 33 is U-shaped in cross section transverse U-yoke extending in the transverse direction 36. At this U-Querjoch is the Coding bar 39 formed in one piece.

Das um 90° abgewinkelte Fixierfreiende 41 greift in Montagestellung der Bodenschale 33 in eine komplementär ausgebildete Ausnehmung 42 der Randleiste 38 ein. Der andere, eine Schalenseitenwand 43 bildende U-Schenkel der Bodenschale 33 ist derart ausgebildet, daß er in das Material der Gehäuseseitenwand 34 bzw. der Gehäuseunterseite 35 eingreift und dort z.B. verrastet. The fixation-free end 41, which is angled by 90 °, engages in the mounting position of the base shell 33 into a complementarily designed recess 42 of the edge strip 38 on. The other U-leg of the bottom shell forming a shell side wall 43 33 is designed such that it fits into the material of the housing side wall 34 or the housing underside 35 engages and there e.g. locked.

Durch die vorbeschriebene Konstruktion der Bodenschale 33 und des übrigen Abzweigdosengehäuses ist die erforderliche Relativbewegung zwischen der Bodenschale 33 und dem übrigen Abzweigdosengehäuse vorteilhaft verkürzt, um die Montage bzw. Demontage der Bodenschale 33 zu erzielen.Due to the above-described construction of the bottom shell 33 and the rest of the junction box housing is the required relative movement between the bottom shell 33 and the rest of the junction box advantageously shortened to To achieve assembly or disassembly of the bottom shell 33.
