Abstract

In order to connect cables to printed circuit boards disposed in an equipment housing, the back ends of the printed circuit boards are equipped with female multi-point connectors. The female multi-point connectors are inserted into male multi-point connectors which are fastened to the front side of a rear wall panel extending transversely to the printed wiring boards. The male multi-point connectors have straight pins which extend through holes in the rear wall panel and project beyond the back side of the rear wall panel. Guide frames for female multi-point connectors are mounted on the back side of the rear wall panel and surround rows of projecting pins. The female multi-point connectors are connected to cables and inserted into the guide frames, thereby electrically connecting the cables to the printed circuit boards. If desired, male multi-point connectors may be fastened to the front ends of the printed circuit boards, and these male multi-point connectors are enclosed by guide frames whose dimensions are matched to the dimensions of the front plates which would otherwise be attached to the printed circuit boards. The printed circuit boards can then be mounted within the equipment housing via the guide frames.

Description

Die Erfindung bezieht sich auf eine Vorrichtung für die Verbindung von Kabeln mit den Anschlüssen von Leiterplatten, die elektronische Bauelemente tragen und in Magazinen parallel zueinander angeordnet sind.The invention relates to a device for connecting cables to the connections of printed circuit boards which carry electronic components and are arranged in magazines parallel to one another.

Leiterplatten mit elektrischen bzw. elektronischen Bauelementen werden häufig in Geräten jeweils mit einer Rückwandleiterplatte verbunden, auf der die Leiterbahnen für die gegenseitige Verbindung der Anschlüsse der einzelnen Leiterplatten angeordnet sind. Von der Rückwandverdrahtungsplatte gehen auch Leitungen bzw. Kabel zu externen Einheiten oder Geräten aus.Printed circuit boards with electrical or electronic components are often connected to a backplane circuit board on which the conductor tracks for the mutual connection of the connections of the individual circuit boards are arranged. Lines or cables to external units or devices also extend from the backplane wiring board.

Die Rückwandleiterplatte, die z. B. in Multilayer-Technik gebildet ist, kann mit Einpreßstiften versehen werde, die bedarfsweise mit metallisierten Bohrungen der Rückwandleiterplatte Kontakte bilden. Die Einpreßstifte ragen über die beiderseitigen Leiterplattenebenen hinaus. Auf derjenigen Seite der Rückwandverdrahtungsplatte, die den elektronische Bauelemente tragenden Leiterplatten zugewandt ist, umgeben Rahmen jeweils parallele Reihen von Einpreßstiften, die in einem für Steckverbinder festgelegten Abstand voneinander angeordnet sind. Die Rahmen dienen als Führung für Federleisten, die mit den Leiterplatten verbunden sind. Auf der den Leiterplatten abgewandten Seite der Rückwandleiterplatte sind an den Enden der parallelen Reihen von Einpreßstiften Abstandshalter angeordnet, auf denen jeweils weitere Rahmen befestigt sind, die die über die Abstandshalter hinausragenden Enden der Einpreßstifte umgeben. Auf den zwischen der Rückwandleiterplatte und der Unterseite der Rahmen verlaufenden Abschnitten der Einpreßstifte können Wire-Wrap-Verbindungen angeordnet sein. Die Rahmen bilden Führungen für Steckerelemente, die auf die Enden der Einpreßstifte aufgesteckt werden.The backplane, the z. B. is formed in multilayer technology, can be provided with press-in pins, which form contacts with metallized holes in the backplane circuit board if necessary. The press-in pins protrude beyond the printed circuit board levels on both sides. On that side of the backplane wiring board which faces the printed circuit boards carrying electronic components, frames surround parallel rows of press-fit pins, which are arranged at a distance from one another which is defined for plug connectors. The frames serve as a guide for female connectors that are connected to the circuit boards. At the ends of the parallel rows of press-in pins, spacers are arranged on the side of the backplane printed circuit board facing away from the printed circuit boards, on each of which further frames are fastened, which surround the ends of the press-in pins projecting beyond the spacers. Wire-wrap connections can be arranged on the sections of the press-in pins running between the backplane and the underside of the frame. The frames form guides for plug elements which are pushed onto the ends of the press-in pins.

Der Aufwand für die Verbindung der die elektronischen Bauelemente tragenden Leiterplatten mit Kabeln ist bei der vorstehend beschriebenen Anordnung relativ groß. Die für den Anschluß der Kabelstecker vorgesehenen Rahmen sind hauptsächlich nur zusammen mit den Einpreßstiften in Rückwandleiterplatten einsetzbar.The effort for connecting the circuit boards carrying the electronic components to cables is relatively great in the arrangement described above. The frames provided for the connection of the cable connectors can mainly only be used together with the press-in pins in the backplane.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung für den Anschluß von Kabeln an mit elektronischen Bauelementen bestückten Leiterplatten zu entwickeln, die bei möglichst geringem Aufwand einen Anschluß von Kabeln mit den Vorderseiten und/oder den Rückseiten der Leiterplatten ermöglicht.The invention has for its object to develop a device for connecting cables to printed circuit boards equipped with electronic components, which enables the connection of cables to the front and / or the rear sides of the printed circuit boards with as little effort as possible.

Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 beschriebenen Maßnahmen gelöst. Die auf die Rückwandverdrahtungsplatte aufgesetzten Führungsrahmen sind Leergehäuse von Messerleisten. Es werden deshalb für die Verbindung der Leiterplatten mit der Rückwandleiterplatte und den Kabelsteckern kommerziell verfügbaren Teile eingesetzt, die in größerem Umfang auch noch anderweitig für die Herstellung von Verbindungen verwendet werden. Damit läßt sich eine besonders wirtschaftliche Lösung erreichen. Falls die auf einer Schmalseite der Leiterplatte möglichen externen Anschlüsse nicht aureichen, kann auch noch die Vorderseite mit einer Messerleiste versehen werden, die in Verbindung mit einem Führungsrahmen an die Stelle der üblichen Frontplatten tritt. Der Führungsrahmen wird an den horizontalen Tragschienen angeschraubt. Der Führungsrahmen, der die Messerleiste an der Vorderseite der jeweiligen Leiterplatte umgibt, ist ein Teil, das unter Umständen nicht so vielseitig verwendbar ist wie die übrigen Bauelemente für die Herstellung der Verbindungen von den Leiterplatten zu der Rückwandleiterplatte bzw. zu den Kabelsteckern. Da für die Rückwandleiterplatte nur kommerziell verfügbare, kostengünstige Messerleisten und Leergehäuse benötigt werden, um die Anschlußmöglichkeit für Kabel zu schaffen, ist es zweckmäßig, die Rückwandleiterplatten an allen Leiterplattenplätzen mit diesen Bauelementen auszustatten, auch wenn nicht alle Leiterplattenplätze im jeweiligen Gerät von Anfang an mit Leiterplatten besetzt werden. Der Aufwand, der sich für die Bestückung aller Leiterplattenplätze mit Verbindungselementen ergibt, ist wesentlich geringer als der für eine nachträgliche Erweiterung erforderliche Aufwand, wenn das Gerät erweitert werden soll und zusätzliche Leiterplatten in die vorhandenen Leerstellen eingesetzt werden müssen.The object is achieved by the measures described in claim 1. The guide frames placed on the backplane wiring board are empty housings for male connectors. Therefore, commercially available parts are used for the connection of the printed circuit boards to the rear wall printed circuit board and the cable connectors, which parts are also used to a large extent for the production of connections. A particularly economical solution can thus be achieved. If the external connections possible on a narrow side of the circuit board are not sufficient, the front can also be provided with a male connector, which replaces the usual front plates in conjunction with a guide frame. The guide frame is screwed onto the horizontal mounting rails. The guide frame, which surrounds the male connector on the front of the respective circuit board, is a part that may not be as versatile as the other components for making the connections from the circuit boards to the backplane circuit board or to the cable connectors. Since only commercially available, inexpensive male connectors and empty housings are required for the backplane in order to provide the possibility of connecting cables, it is expedient that To equip backplane circuit boards at all circuit board locations with these components, even if not all circuit board locations in the respective device are occupied with circuit boards from the start. The effort that results in equipping all circuit board spaces with connecting elements is significantly less than the effort required for subsequent expansion if the device is to be expanded and additional circuit boards have to be inserted into the existing empty spaces.

Bei einer bevorzugten Ausführungsform ist vorgesenen, daß die in die Führungsrahmeneinsteckbaren Federleisten mit Schneidelementen für den Anschluß von Drähten in Schneid-Klemm-Technik ausgebildet sind. Die einzelnen Adern der anzuschließenden Rundleiterkabel lassen sich mit den vorstehend beschriebenen Kabelsteckern rationell und schnell verbinden. Es ist dabei möglich, zu- und abgehende Leitungen über beispielsweise 64polige Kabelstecker anzuschließen.In a preferred embodiment it is provided that the spring strips which can be inserted into the guide frame are designed with cutting elements for the connection of wires using insulation displacement technology. The individual wires of the round conductor cables to be connected can be connected efficiently and quickly using the cable connectors described above. It is possible to connect incoming and outgoing lines using, for example, 64-pin cable connectors.

Eine Rückwandleiterplatte 1 enthält parallele Reihen von Löchern 2, die in einem vorgegebenen Abstand voneinander angeordnet sind. Der Abstand entspricht der Teilung von Stiften 3 einer Messerleiste 4. Die Messerleiste 4 enthält parallele Reihen von geraden Stiften 3, von denen einer im einzelnen in der Zeichnung dargestellt ist. An den beiden Enden der Messerleiste 4 sind Löcher 5 vorgesehen, die parallel zu den Stiften 3 verlaufen. Mittels in die Löcher eingesetzter Schrauben 6 wird die Messerleiste 4 an der Rückwandleiterplatte 1 befestigt. In montiertem Zustand ragen die Stifte 3 über die Oberfläche der Rückwandleiterplatte 1 hinaus. In die Messerleiste 4 sind Leiterplatten 7, die elektrische bzw. elektronische Bauelemente tragen, mit Federleisten 8 eingesteckt, die jeweils an der rückwärtigen Seite der Messerleiste 4 befestigt sind.A backplane 1 contains parallel rows of holes 2 arranged a predetermined distance apart. The distance corresponds to the division of pins 3 of a knife bar 4. The knives bar 4 contains parallel rows of straight pins 3, one of which is shown in detail in the drawing. Holes 5 are provided at both ends of the male connector 4 and run parallel to the pins 3. By means of screws 6 inserted into the holes, the male connector 4 is fastened to the backplane 1. In the assembled state, the pins 3 protrude beyond the surface of the backplane 1. Printed circuit boards 7, which carry electrical or electronic components, are inserted into the male connector 4 with female connectors 8, each of which is attached to the rear side of the male connector 4.

Die über die Oberfläche der Rückwandleiterplatte 1 hinausragenden Enden der Stifte 3 sind in parallelen Reihen von einem Führungsrahmen 9 für Messerleisten umgeben. Die Führungsrahmen 9 haben Löcher 10, durch die die Stifte 3 hindurchragen. Die Schrauben 6 und nicht näher dargestellte Muttern dienen gleichzeitig zur Befestigung der Führungsrahmen 9 an der Rückwandleiterplatte 1. Die Führungsrahmen 9 weisen an ihren Seiten längliche Vorsprünge 11 mit Ausnehmungen 12 auf, in die Verriegelungshaken 13 mit ihren gabelförmigen Enden 14 eingesetzt werden. Der Führungsrahmen 9 mit den über die Löcher 10 hinausragenden Enden der Stifte 3 wird mit einer Federleiste 15 vereinigt, die nach einer Seite vorstehende Schneidelemente 16 für den Anschluß von Drähten in Schneid-Klemm-Technik aufweist. An der Federleiste 15 wird ein Drahtführungselement 17 befestigt, das nicht näher dargestellte Kanäle enthält, die an den Stellen der Schneidelemente 16 enden. In die Kanäle werden die freien Enden der Drähte 18 eines Kabels 19 eingesteckt, das zu externen Einheiten oder Geräten verlegt sein kann. Die Federleiste 15 enthält Ausnehmungen 20 in den Längsseiten. Zwei Kabelgehäusehalbschalen 21, 22 weisen Vorsprünge 23 auf, die in die Ausnehmungen 20 eingreifen, wenn die Kabelgehäusehalbschalen 21, 22 über der Federleiste 15 und dem Drahtführungselement 17 aneinandergelegt werden. Dabei greifen nicht näher bezeichnete Rastelemente der Gehäusehalbschalen ineinander und bewirken eine feste Verbindung zwischen den Gehäusehalbschalen 21, 22 und der Federleiste 15 bzw. dem Drahtführungselement 17. In den Gehäusehalbschalen 21, 22 sind Ausnehmungen 24 für den Durchlaß der Kabel 19 vorgesehen. Weiterhin befinden sich in den Gehäusehalbschalen 21, 22 Einspannelemente 25 für die Kabel 19.The ends of the pins 3 protruding beyond the surface of the backplane 1 are surrounded in parallel rows by a guide frame 9 for male connectors. The guide frames 9 have holes 10 through which the pins 3 protrude. The screws 6 and nuts (not shown in more detail) serve at the same time for fastening the guide frame 9 to the rear wall circuit board 1. The guide frames 9 have on their sides elongated projections 11 with recesses 12, into which locking hooks 13 with their fork-shaped ends 14 are inserted. The guide frame 9 with the ends of the pins 3 projecting beyond the holes 10 is combined with a spring strip 15 which has cutting elements 16 projecting to one side for the connection of wires using insulation displacement technology. On the female connector 15, a wire guide member 17 is attached, which contains channels, not shown, which end at the locations of the cutting elements 16. The free ends of the wires 18 of a cable 19 are inserted into the channels and can be laid to external units or devices. The female connector 15 contains recesses 20 in the long sides. Two cable housing half-shells 21, 22 have projections 23 which engage in the recesses 20 when the cable housing half-shells 21, 22 are placed against one another above the female connector 15 and the wire guide element 17. In this case, latching elements of the housing half-shells, which are not specified, engage in one another and bring about a firm connection between the housing half-shells 21, 22 and the female connector 15 or the wire guide element 17. In the housing half-shells 21, 22, recesses 24 are provided for the passage of the cables 19. Furthermore, there are clamping elements 25 for the cables 19 in the housing half-shells 21, 22.

Auf der Rückwandleiterplatte 1 ist eine der Anzahl der Leiterplattenplätze entsprechende Zahl von Messerleisten 4 und Führungsrahmen 9 befestigt. Der Übersichtlichkeit wegen sind diese Teile in Fig. 1 nur einmal dargestellt. Bedarfsweise werden die Leiterplatten 7 in die entsprechenden Leiterplattenplätze eingesetzt. Über die durchkontaktierten Löcher 2, die mit nicht dargestellten Leiterbahnen der Rückwandleiterplatte verbunden sind, können Verbindungen zwischen Stiften 3 von verschiedenen Messerleisten 4 erzeugt werden. Gegebenenfalls wird als Rückwandleiterplatte eine Multilayer-Platte verwendet.A number of male connectors 4 and guide frame 9 corresponding to the number of printed circuit board locations is fastened on the rear wall circuit board 1. For the sake of clarity, these parts are only shown once in FIG. 1. If necessary, the circuit boards 7 are inserted into the corresponding circuit board slots. Connections between pins 3 of different male connectors 4 can be produced via the plated-through holes 2, which are connected to conductor tracks of the backplane circuit board, not shown. A multilayer board may be used as the backplane.

Die Gehäusehalbschalen 21, 22 sind mit seitlichen Vorsprüngen 25 versehen, die Aussparungen zur Aufnahme der Enden der Verriegelungshaken 13 haben, die mit Rastnasen 26 gehalten werden. Bei der Messerleiste 4 und dem Führungsrahmen 9 handelt es sich um kommerziell verfügbare, in großem Umfang verwendete Bauteile, die nicht nur für Rückwandleiterplatten eingesetzt werden. Diese Bauteile sind kostengünstig zu erhalten. Daher läßt sich die Vorrichtung für den Anschluß der Kabel an die Leiterplatten 7 wirtschaftlich herstellen.The housing half-shells 21, 22 are provided with lateral projections 25, which have recesses for receiving the ends of the locking hooks 13, which are held with locking lugs 26. The male connector 4 and the guide frame 9 are commercially available, widely used components that are not only used for backplane boards. These components can be obtained inexpensively. Therefore, the device for connecting the cables to the circuit boards 7 can be produced economically.

An den vorderen Stirnseiten 27 können bedarfsweise Messerleisten 28 befestigt sein, wenn die Anzahl der Anschlüsse an der hinteren Stirnseite 29 nicht ausreicht. Die Messerleiste 28 ist von einem Führungsrahmen 30 umgeben, dessen Abmessungen an die Frontplatten 31 von Leiterplatten angepaßt ist, die üblicherweise an Schienen 32 befestigt sind. Der Führungsrahmen 30 enthält an seinen Enden 33, 34 Aussparungen 35 zur Aufnahme von Einsätzen, mit denen er an den Schienen 32 angeschraubt wird. Die Befestigung kann mittels Schrauben und Gewindeleisten erfolgen, die in nicht näher bezeichnete Nuten der Schienen 32 eingesetzt sind. Vorzugsweise sind die Aussparungen 35 länglich ausgebildet und dienen zur Aufnahme eines elastischen Zwischenstücks 36, das mittels der Schrauben 37 mit der Gewindeleiste 38 verbunden wird. Der Führungsrahmen 30 umgibt die Messerleiste 28, deren Messerstifte 39 in Federn einer Federleiste 40 eingreifen, die mit der Messerleiste 28 verbunden wird. Die Federleiste 40 entspricht im Aufbau der Federleiste 15. Gleiche Elemente an den Federleisten 15 und 40 wurden daher mit gleichen Bezugsziffern versehen.Knife strips 28 can be fastened to the front end faces 27 if necessary if the number of connections on the rear end face 29 is not sufficient. The male connector 28 is surrounded by a guide frame 30, the dimensions of which are adapted to the front plates 31 of printed circuit boards which are usually fastened to rails 32. The guide frame 30 contains at its ends 33, 34 recesses 35 for receiving inserts with which it is screwed onto the rails 32. The attachment can be carried out by means of screws and threaded strips, which are inserted into grooves in the rails 32, which are not described in more detail. The recesses 35 are preferably elongated and serve to receive an elastic intermediate piece 36, which is connected to the threaded strip 38 by means of the screws 37. The guide frame 30 surrounds the male connector 28, the male pins 39 of which engage in the springs of a female connector 40 which is connected to the male connector 28. The structure of the female connector 40 corresponds to the female connector 15. The same elements on the female connectors 15 and 40 have therefore been given the same reference numbers.

Auf die Federleiste 40 wird ein Drahtführungselement 41 aufgesetzt, dessen Aufbau demjenigen des Drahtführungselements 17 entspricht. Das Drahtführungselement 41 enthält Kanäle, in die die freien Enden von Drähten 43 eingeführt sind. Die Drähte 43 verlaufen bis zu Stellen, an denen sie mit den Schneidelementen 16 in Schneid-Klemm-Technik verbunden sind. Die Drähte gehören zu einem Kabel 44, das zu externen Einheiten oder zu anderen Verbindungsstellen auf der Vorderseite oder der Rückseite der Leiterplatten 7 verläuft. Die Federleiste 40 und das Drahtführungselement 41 werden von zwei Gehäusehalbschalen 45, 46 in deren vereinigtem Zustand gehalten. Die Gehäusehalbschalen 45, 46 stimmen im Aufbau mit den Gehäusehalbschalen 21, 22 überein. In Aussparungen 47 von seitlichen Vorsprüngen der Gehäusehalbschalen 45, 46 sind Verriegelungshaken 13 einsetzbar, deren gabelförmige Enden in Ausnehmungen 48 des Führungsrahmens 30 eingreifen.A wire guide element 41 is placed on the female connector 40, the structure of which corresponds to that of the wire guide element 17. The wire guide element 41 contains channels into which the free ends of wires 43 are inserted. The wires 43 run to the point at which they are connected to the cutting elements 16 using insulation displacement technology. The wires belong to a cable 44 which runs to external units or to other connection points on the front or the back of the printed circuit boards 7. The female connector 40 and the wire guide element 41 are held in their combined state by two housing half-shells 45, 46. The housing half-shells 45, 46 correspond in construction to the housing half-shells 21, 22. Locking hooks 13, the fork-shaped ends of which engage in recesses 48 of the guide frame 30, can be inserted into recesses 47 in the lateral projections of the housing half-shells 45, 46.
