Description

Die Erfindung betrifft eine Anordnung zum geordneten Führen von Kabelenden zu Steckkontakten einer Steckkontaktplatte, wobei für die Kabelenden eine Zugabfangung vorgesehen ist.The invention relates to an arrangement for the orderly routing of cable ends to plug contacts of a plug-in contact plate, strain relief being provided for the cable ends.

Wenn eine Vielzahl von Kabelenden zu einer Steckkontaktplatte geführt werden soll, ist eine geordnete Führung der Kabelenden notwendig.If a large number of cable ends are to be led to a plug contact plate, an orderly routing of the cable ends is necessary.

Aus der DE-A-27 58 782 ist eine Anordnung mit Kammleisten bekannt, die zum geordneten Führen von Kabelenden zu Steckkontakten einer Steckkontaktplatte dient. Für die Kabelenden ist eine Zugabfangung vorgesehen. Die Kammleisten weisen Aussparungen zum Führen jeweils einer Reihe von Kabelenden auf mit federnden Klemmvorrichtungen und sind in einer Ebene an einer U-förmigen Montageschiene angeordnet. Auf dieser Montageschiene befindet sich ein Schaltgerät, in das die freien Kabelenden um 90° versetzt zu den Kammleisten eingeführt sind.From DE-A-27 58 782 an arrangement with comb strips is known, which is used for the orderly routing of cable ends to plug contacts of a plug contact plate. A strain relief is provided for the cable ends. The comb strips have cutouts for guiding a number of cable ends with resilient clamping devices and are arranged in one plane on a U-shaped mounting rail. On this mounting rail there is a switchgear into which the free cable ends are inserted, offset by 90 ° to the comb strips.

Aus der EP 174 050 A2 ist ein Verfahren und eine Vorrichtung zum Ordnen und Ausrichten flexibler, isolierter Leiter eines ungeordneten elektrischen Leiterbündels bekannt. Die ungeordneten Leiter werden dort von einer geordneten Stelle her zwischen den fluchtenden Zinken zweier Kämme hindurchgezogen. Die Leiter werden dann in Verengungen zwischen den Zinken eines Kammes verklemmend eingedrückt. Aus der US PS 3,861,015 sind Klammern zur Halterung von Kabeldrähten bekannt. Diese Klammern bestehen aus Federzungen, mittels derer die Kabeldrähte gegen eine Grundplatte fixiert werden können. Zur Halterung von Drahtbündeln können durch die Grundplatte Pflöcke gesteckt werden, zwischen denen die Drahtbündel aufgenommen werden.EP 174 050 A2 discloses a method and a device for arranging and aligning flexible, insulated conductors of a disordered electrical conductor bundle. The disordered conductors are pulled from an orderly position between the aligned prongs of two combs. The conductors are then pressed into a constriction between the teeth of a comb. Clamps for holding cable wires are known from US Pat. No. 3,861,015. These clips consist of spring tongues, by means of which the cable wires can be fixed against a base plate. To hold wire bundles, pegs can be inserted through the base plate, between which the wire bundles are picked up.

Die US PS 4,679,123 behandelt ein System zum Ordnen von Kabeln. Jeweils ein Kabelbündel wird zu einem von mehreren übereinander angeordneten Arrays geführt. Auf diesen Arrays sind Steckerleisten angeordnet. Jeweils ein Kabel eines Bündels führt zu einer Steckerleiste des zugehörigen Arrays. Pro Kabelbündel ist an der Innenwand des Kabelgestellrahmens eine U-förmige Klammer vorgesehen, die jeweils ein Kabelbündel umschließt und am Rahmen fixiert. Damit sich die einzelnen Kabelbündel gegenseitig nicht stören, sind die U-förmigen Klammern gestuft an der Gestellrahmen-Innenwand angeordnet.US Pat. No. 4,679,123 deals with a system for arranging cables. One cable bundle each is led to one of several arrays arranged one above the other. Socket strips are arranged on these arrays. One cable from each bundle leads to a connector strip of the associated array. Each cable bundle is on the inner wall of the cable frame a U-shaped bracket is provided, each enclosing a cable bundle and fixed to the frame. So that the individual bundles of cables do not interfere with each other, the U-shaped brackets are arranged in stages on the inner wall of the frame.

Aus der DE-OS 22 28 780 ist eine Zugentlastungsanordnung für die einer Steckerleiste zugeführten Kabel bekannt. Dort ist eine als Klemmteil ausgebildete rahmenförmige Kabelaufnahmevorrichtung vorgesehen. Der Rahmen weist einen Schlitz auf, durch den Kabel oder Einzelleiter zu Steckkontakten in einer Reihe geordnet zuführbar sind. Eine Zugentlastung wird durch Einklemmen der Kabel oder Einzelleiter erreicht. Anstelle eines Rahmens kann nach der DE-OS 22 28 780 auch eine Kabelaufnahmevorrichtung in Form eines Stabes benutzt werden, der gegen die Steckerleiste fixiert ist. Am freien Ende weist dieser Stab einen zu einer Schlaufe formbaren Riemen auf. Durch diese Schlaufe werden die Kabelenden nebeneinander zu den Steckkontakten geführt. Die Zugentlastung der Kabelenden erfolgt durch Zusammenziehen der Schlaufe, wobei die Kabelenden fest umgriffen werden.From DE-OS 22 28 780 a strain relief arrangement for the cables fed to a connector strip is known. A frame-shaped cable receiving device designed as a clamping part is provided there. The frame has a slot through which cables or individual conductors can be supplied in a row in order to plug contacts. Strain relief is achieved by clamping the cables or individual conductors. Instead of a frame can be used according to DE-OS 22 28 780 also a cable receiving device in the form of a rod which is fixed against the power strip. At the free end, this rod has a strap that can be formed into a loop. This loop leads the cable ends next to each other to the plug contacts. The cable ends are relieved of tension by pulling the loop together, firmly gripping the cable ends.

Aus der EP 27 696 A1 ist es bekannt, geschirmte Kabelenden geordnet in Richtung einer Klemmleiste zu führen. Hierzu sind Kammern vorgesehen, die an der Kabelzuführungsseite mit Schlitzen versehene Kabelhalterungen aufweisen. Die Einzelleiter der Kabel werden in die Schlitze eingelegt und mittels elastischen Pfropfen, die über die Einzelleiter in die Schlitze eingesteckt werden, zugabgefangen.From EP 27 696 A1 it is known to guide shielded cable ends in an orderly manner in the direction of a terminal strip. For this purpose, chambers are provided which have cable holders provided with slots on the cable feed side. The individual conductors of the cables are inserted into the slots and caught by means of elastic plugs which are inserted into the slots via the individual conductors.

Aufgabe der Erfindung ist es, die einleitend genannte Anordnung so auszubilden, daß zumindest zwischen einigen benachbarten Kabelreihen Leiterplatten ohne Störung durch Kabel eingeschoben werden können. Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Die Unteransprüche zeigen vorteilhafte Ausgestaltungen der Anordnung auf. Der Anspruch 4 ermöglicht insbesondere eine Führung der Leiterplatten.The object of the invention is to design the arrangement mentioned in the introduction in such a way that circuit boards can be inserted at least between some adjacent rows of cables without interference from cables. This object is achieved by the features of patent claim 1. The subclaims show advantageous configurations of the arrangement. The claim 4 allows in particular a leadership of the circuit boards.

Die Anordnung nach der Erfindung besitzt den Vorteil, daß sie modular erweiterbar - bei Bedarf können weitere Kabelführungselemente nachgerüstet werden - und leicht modifizierbar ist. Durch den Abstand zwischen den Kabelführungselementen können an beliebigen Stellen Leiterplatten zusätzlich eingefügt werden oder gegen andere ausgetauscht werden. Dies ist insbesondere dann notwendig, wenn Module auf der Frontseite der Steckkontaktplatte ausgetauscht werden, da dann "Shuntboards" in die auf der Plattenrückseite befindlichen Kontaktleisten in beispielsweise 225-poliger Ausführung einzuschieben sind. Eine Zugabfangung der Koaxialkabelenden ist derart vorgesehen, daß die Steckverbinder in der Steckkontaktplatte möglichst wenig beansprucht werden.The arrangement according to the invention has the advantage that it can be expanded in a modular manner - further cable routing elements can be retrofitted if necessary - and can be easily modified. Due to the distance between the cable routing elements, printed circuit boards can be inserted at any point or exchanged for others. This is particularly necessary when modules on the front of the plug-in contact plate are exchanged, since "shunt boards" must then be inserted into the contact strips located on the back of the plate, for example in a 225-pin version. A strain relief of the coaxial cable ends is provided in such a way that the connectors in the plug contact plate are stressed as little as possible.

Die Aufsicht nach Fig. 1 zeigt die Führung der Kabelenden 1 - hier Koaxialkabelenden - zu der Steckkontaktplatte 2. Die Steckverbindungen zwischen den Koaxialkabelenden 1 und der Steckkontaktplatte 2 erfolgt hier über BNC-Stecker 3 auf der Rückseite der Steckkontaktplatte 2. Die Steckkontaktplatte 2 befindet sich auf der Vorderseite eines rahmenartigen Baugruppenträgers, von dem in Fig. 1 die beiden Seitenwände 4 und die unteren Verbindungsschienen 5 des Baugruppenträgerrahmens zu sehen sind. Die Befestigung der Steckkontaktplatte 2 am Baugruppenträgerrahmen kann beispielsweise an den Profilschenkeln der Verbindungsschienen 5 oder durch Flansche erfolgen. Im Abstand von beispielsweise 5 inches zur Steckkontaktplatte 2 sind in einer Ebene parallel zur Steckkontaktplatte kammartige Kabelführungselemente 8 senkrecht nebeneinander angeordnet. Wie Fig. 2 zeigt, bilden die Kabelführungselemente 8 die Rückplatten des Baugruppenträgers. Sie bestehen jeweils aus L-Profilen, die endseitig flach ausgebildet sind (Fig. 1 und 2), damit sie an der hinteren unteren Schiene 5 und der hinteren oberen Schiene 6 aufliegen können und mit diesen Schienen durch Schrauben 7 verschraubt werden können. Demnach erfolgt die Fixierung der Steckkontaktplatte 2 gegen die Kabelführungselemente 8 über den Baugruppenträgerrahmen 4, 5, 6, als Befestigungsmittel. Wie insbesondere aus Fig. 2 ersichtlich ist, weisen die Kabelführungselemente 8 in ihrer Ebene parallel zur Steckkontaktplatte 2 stirnseitig Aussparungen 9 auf, welche den Kabelführungselementen 8 von der Rückseite aus gesehen kammartiges Aussehen verleihen. Die Aussparungen 9 sind schlitzartig und am Schlitzgrund halbkreisförmig ausgebildet. Die Schlitzbreite und der halbkreisförmige Schlitzgrund sind so bemessen, daß durch jeden Schlitz gerade ein Koaxialkabel geführt werden kann. Durch die übereinander angeordneten Schlitze eines Kabelführungselementes 8 kann jeweils eine senkrechte Reihe von Koaxialkabelenden geführt werden. Wie die Figuren 1 und 2 weiter zeigen, können die Kabelführungselemente 8 parallel mit Abstand einzeln nebeneinander oder paarweise mit Abstand parallel nebeneinander angeordnet werden. Hierdurch ergibt sich ein matrixartiges Ordnungsprinzip. Bei der paarweisen Anordnung liegen jene Schenkel der L-Profile, die keine Aussparungen tragen, dicht nebeneinander und sind zweckmäßigerweise miteinander verschraubt. Der Abstand zwischen den einzeln oder paarweise nebeneinander angeordneten Kabelführungselementen 8 ist so bemessen, daß Leiterplatten 10, die beispielsweise als Shuntboards ausgebildet sind, ohne Störung durch die Kabelenden in die Freiräume zwischen jeweils zwei schlitzseitig benachbarten Kabelführungselementen 8 in Richtung auf die Steckkontaktplatte 2 zu einschiebbar sind. Die Shuntboards 10 weisen auf ihrer einen Stirnseite eine 225-polige Kontaktleiste 11 auf, die nach dem Einschieben in eine entsprechende Kontaktleiste 12 auf der Steckkontaktplatte 2 eingreift. Auf ihrer anderen Stirnseite weisen die Shuntboards 10, um eine gute Zugänglichkeit und Handhabbarkeit zu gewährleisten, Handgriffe 15 auf, die über die Rückplattenebene in Richtung Bedienungspersonal herausragen (Fig. 4). Die Kontaktleiste 12 oder eine Vielzahl solcher Kontaktleisten, falls mehrere Shuntboards 10 vorgesehen sind, befindet sich immer zwischen einer oder mehreren senkrechten Reihen von Steckkontakten 3. Um eine Fehlbedienung bzw. eine Beschädigung der 225-poligen Steckverbinder - beispielsweise durch Verkanten der Shuntboards - zu vermeiden, werden die Shuntboards an der Unter- und Oberseite in nutartigen Schienen 13 geführt. Diese Schienen 13 können an den Schienen 5 und 6 des Baugruppenträgerrahmens befestigt sein.1 shows the routing of the cable ends 1 - here coaxial cable ends - to the plug contact plate 2. The plug connections between the coaxial cable ends 1 and the plug contact plate 2 are made here via BNC plug 3 on the back of the plug contact plate 2. The plug contact plate 2 is located on the front of a frame-like rack, of which the two side walls 4 and the lower connecting rails 5 of the rack frame can be seen in FIG. 1. The plug contact plate 2 can be attached to the subrack frame, for example, on the profile legs of the connecting rails 5 or by flanges. At a distance of, for example, 5 inches from the plug contact plate 2, comb-like cable guide elements 8 are arranged vertically next to one another in a plane parallel to the plug contact plate. 2 shows, the cable routing elements 8 form the back plates of the subrack. They each consist of L-profiles, which are flat at the ends (FIGS. 1 and 2), so that they can rest on the rear lower rail 5 and the rear upper rail 6 and can be screwed to these rails by screws 7. Accordingly, the plug-in contact plate 2 is fixed against the cable guide elements 8 via the subrack frame 4, 5, 6, as a fastening means. As can be seen in particular from FIG. 2, the cable guide elements 8 have cutouts 9 in their plane parallel to the plug-in contact plate 2 on the end face, which give the cable guide elements 8 a comb-like appearance when viewed from the rear. The recesses 9 are slit-like and semicircular at the slit base. The slot width and the semicircular slot base are dimensioned such that a coaxial cable can be passed through each slot. Through the slots of a cable guide element 8 arranged one above the other, a vertical row can be formed from coaxial cable ends. As FIGS. 1 and 2 further show, the cable guiding elements 8 can be arranged in parallel at a distance individually next to one another or in pairs at a distance in parallel next to one another. This results in a matrix-like ordering principle. In the paired arrangement, those legs of the L-profiles that do not have any cutouts lie close together and are expediently screwed together. The distance between the individually or in pairs side by side cable guide elements 8 is dimensioned so that printed circuit boards 10, which are designed, for example, as shunt boards, can be inserted without interference from the cable ends into the spaces between two adjacent cable guide elements 8 in the direction of the plug contact plate 2 . The shunt boards 10 have on one end face a 225-pin contact strip 11 which, after being inserted, engages in a corresponding contact strip 12 on the plug-in contact plate 2. In order to ensure good accessibility and manageability, the shuntboards 10 have handles 15 on their other end faces which protrude beyond the backplate level in the direction of the operating personnel (FIG. 4). The contact strip 12 or a plurality of such contact strips, if a plurality of shunt boards 10 are provided, is always located between one or more vertical rows of plug contacts 3. In order to avoid incorrect operation or damage to the 225-pin plug connector, for example by tilting the shunt boards , The shunt boards are guided on the bottom and top in groove-like rails 13. These rails 13 can be attached to the rails 5 and 6 of the subrack.

Im Bereich der Aussparungen 9 der Kabelführungselemente 8 sind federnde Klemmvorrichtungen 14 vorgesehen. Diese federnden Klemmvorrichtungen bestehen jeweils aus paarweise angeordneten Federbügeln aus Flachmaterial (Fig. 3) pro einzuklemmenden Kabel. Die Federbügel sind mit Schrauben 15 auf jenen Schenkeln der aus L-Profilen bestehenden kammartigen Kabelführungselementen 8 aufgebracht, die keine Aussparungen tragen, d.h. auf jenen Schenkeln, die senkrecht zur Steckkontaktplatte 2 ausgerichtet sind (Fig. 1 und 4). Die Federbügel sind fluchtend hinter den Aussparungen 9 angebracht, wie die Schnittdarstellung nach Fig. 4 zeigt. Somit durchlaufen die Koaxialkabelenden nach Einlegen in die Aussparungen 9 der Kabelführungselemente, Einklemmen in die federnden Klemmvorrichtungen 14 und Einstecken der BNC-Stecker 3 auf der Steckkontaktplatte 2 den Baugruppenträger ohne Richtungsänderung.Resilient clamping devices 14 are provided in the area of the recesses 9 of the cable guide elements 8. This Resilient clamping devices each consist of pairs of spring clips made of flat material (Fig. 3) per cable to be clamped. The spring clips are applied with screws 15 to those legs of the comb-like cable guide elements 8 consisting of L-profiles which do not have any cutouts, ie to those legs which are aligned perpendicular to the plug contact plate 2 (FIGS. 1 and 4). The spring clips are mounted in alignment behind the cutouts 9, as the sectional view according to FIG. 4 shows. Thus, after insertion into the recesses 9 of the cable guide elements, clamping into the resilient clamping devices 14 and insertion of the BNC connector 3 on the plug contact plate 2, the coaxial cable ends pass through the subrack without changing the direction.

Die Federklemmbügel weisen kreissektorförmige Ausformungen 16 etwa in der Mitte jeweils eines Federbügels zum Umgreifen des Koaxialkabelmantels auf (Fig. 3). Die freien Enden der Federklemmbügel sind zum leichteren Einführen der Kabel nach außen in Form von Einführungstrichtern gebogen (Fig. 3).The spring clamps have circular sector-shaped formations 16 approximately in the middle of each spring clip for gripping around the coaxial cable sheath (FIG. 3). The free ends of the spring clips are bent outwards in the form of insertion funnels for easier insertion of the cables (Fig. 3).

Eine Alternative zur Ausgestaltung der Kabelführungselemente 8 zeigt Fig. 5. Die Kabelführungselemente 8 sind nun nicht mehr in Form von L-Profilen, sondern plattenartig ausgebildet. Sie sind auch im Gegensatz zum Ausführungsbeispiel nach Fig. 1 für zwei Reihen von Aussparungen 9 konzipiert und zwar für solche benachbarten Reihen, deren Aussparungen entgegengesetzte Öffnungsrichtungen aufweisen. Als Träger für die federnden Klemmvorrichtungen und die plattenartigen Kabelführungselemente 8 dienen bei diesem Ausführungsbeispiel Verbindungsstege 17 zwischen Rahmenunterseite und Rahmenoberseite, auf die die Kabelführungselemente 8 mittig aufgelegt werden können. Die Befestigung der Kabelführungselemente 8 kann - wie zuvor - direkt an den Schienen 5 und 6 oder an den Verbindungsstegen 17 durch Verschrauben erfolgen.An alternative to the design of the cable guide elements 8 is shown in FIG. 5. The cable guide elements 8 are no longer in the form of L-profiles, but rather plate-like. In contrast to the exemplary embodiment according to FIG. 1, they are also designed for two rows of cutouts 9, specifically for those adjacent rows whose cutouts have opposite opening directions. In this exemplary embodiment, connecting webs 17 between the underside of the frame and the top of the frame, on which the cable guide elements 8 can be placed in the center, serve as carriers for the resilient clamping devices and the plate-like cable guide elements 8. The attachment of the cable guide elements 8 can - as before - directly on the rails 5 and 6 or on the connecting webs 17 by screwing.

Fig. 6 zeigt eine perspektivische Gesamtansicht der Anordnung nach der Erfindung. Der Baugruppenträgerrahmen mitsamt Steck-Kontaktplatte ist zwischen zwei senkrecht stehenden Trägerplatten 18 in Bedienungshöhe befestigt. Im seitlichen Rahmenbereich ist eine Sichtöffnung 19 zu sehen. Unterhalb der Kabelführungselemente 8 ist ein Kabelschacht angeordnet, der zur Aufnahme und zur Wegführung der Kabelbündel einer Reihe von Koaxialkabeln dient. In Fig. 6 ist nur eine Reihe von Kabelführungselementen mit Koaxialkabeln bestückt. Ebenso ist nur ein Shuntboard eingeschoben, dessen Handgriff 15 über die Ebene der Kabelführungselemente 8, die die Rückwand des Baugruppenträgers bilden, hinausragt.Fig. 6 shows an overall perspective view of the arrangement according to the invention. The rack with the plug-in contact plate is fastened between two vertical support plates 18 at the operating height. A viewing opening 19 can be seen in the lateral frame area. A cable duct is arranged beneath the cable guide elements 8, which is used to receive and guide the bundles of cables from a series of coaxial cables. In Fig. 6, only a number of cable management elements are equipped with coaxial cables.
