Description

Die Erfindung bezieht sich auf einen indirekten Steckverbinder für die Verbindung von Leiterbahnen einer Leiterplatte mit dem Verdrahtungsfeld eines Baugruppenträgers, wobei in einem Isolierkörper einer Messerleiste vier Reihen von Messerkontakten parallel zueinander befestigt sind, die an den einen Enden in Anschlussstifte übergehen, die in senkrechter Richtung zur Ebene der jeweiligen Leiterplatte umgebogen und mit ihren Enden in Löcher der Leiterplatte einfügbar sind und wobei im Isolierkörper, der an seinen stirnseitigen Enden mittels vorspringender Flansche an der Leiterplatte befestigt ist, im Bereich der Krümmungsstellen derjenigen Anschlussstifte, die dem Rand der Leiterplatte am nächsten angeordnet sind, eine Aussparung vorgesehen ist.The invention relates to an indirect connector for connecting conductor tracks of a circuit board to the wiring field of a subrack, four rows of knife contacts being fastened in parallel to one another in an insulating body of a male connector, which at one end merge into connecting pins which extend in the vertical direction to The plane of the respective printed circuit board is bent and its ends can be inserted into holes in the printed circuit board, and in the insulating body which is attached to the end face of the printed circuit board by means of projecting flanges, in the region of the points of curvature of those connecting pins which are arranged closest to the edge of the printed circuit board , a recess is provided.

Ein derartiger Steckverbinder ist dem Dokument US-A-4 494 818 als bekannt zu entnehmen. Für die auf einer Leiterplatte angeordneten Schaltungen werden die Signaleingänge, die Signalausgänge und die Stromversorgung über die Kontakte derartiger Steckverbinder geführt. Bei einer hohen Bauelementdichte auf der Leiterplatte wird eine grosse Zahl von Anschlussstiften benötigt.Such a connector is known from document US-A-4 494 818. For the circuits arranged on a circuit board, the signal inputs, the signal outputs and the power supply are routed via the contacts of such connectors. With a high component density on the printed circuit board, a large number of connection pins is required.

Bekannt ist nach DIN 41 612 eine Steckverbinderfamilie, deren Eigenschaften auf die Baugruppenträger derart abgestimmt sind, dass Baugruppen mit verschiedenen Steckverbindern der gleichen Familie im gleichen Baugruppenträger gemischt angeordnet werden können.According to DIN 41 612, a connector family is known, the properties of which are matched to the subrack in such a way that assemblies with different plug connectors of the same family can be mixed in the same subrack.

Steckverbinder der Gruppe 1 nach DIN 41 612 sind für Minidrahtanschlusstechnik bestimmt. Es sind Steckverbinder mit einer Zahl von 96 Anschlussstiften bekannt. Diese Steckverbinder bestehen aus drei parallelen Anschlussstiften mit 2,54 mm Stift- und Reihenabstand. Diese Bauform wird auch als C96 bezeichnet. Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der eingangs beschriebenen Art so weiterzuentwickeln, dass bei geringen Abständen zwischen dem Leiterplattenrand und der diesem am nächsten liegenden Reihe von Anschlussstiften die Krümmungsstellen der Anschlussstifte zum Einfügen in Fertigungstoleranzen aufweisende Bohrlöcher elastisch ausdehnbar sind und dass eine hohen Steck- und Ziehkräften widerstehende Verbindung zwischen Messerleiste und Leiterplatte erreichbar ist.Group 1 connectors according to DIN 41 612 are intended for mini wire connection technology. Connectors with a number of 96 pins are known. These connectors consist of three parallel connection pins with 2.54 mm pin and row spacing. This design is also known as the C96. The invention has for its object to further develop a connector of the type described in such a way that with small distances between the edge of the circuit board and the row of connecting pins closest to it, the points of curvature of the connecting pins for insertion boreholes with manufacturing tolerances are elastically expandable and that a high insertion and pulling resistance can be achieved between the male connector and the circuit board.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Krümmungsstellen in der Aussparung frei liegen, dass der Abstand der dem Rand benachbarten Reihe von Anschlussstiften an den Enden der Anschlussstifte vom Rand weniger als 5 mm beträgt und dass die Flansche je an zwei Stellen, die quer zur Längsachse des Isolierkörpers nebeneinander angeordnet sind, über Befestigungsmittel mit der Leiterplatte verbunden sind. Ein Steckverbinder mit der vorstehend beschriebenen Bauform benötigt in senkrechter Richtung zur Ebene der Leiterplatte nicht mehr als vier Teilungen von 5,08 mm. Eine derartige Einbauteilung ist bei Baugruppenträgern nach DIN 41 494 für Baugruppen bzw. deren Frontplatten vorgesehen. Ausserdem kann auf der Leiterplatte das Bohrlochbild für drei Reihen von Anschlussstiften in Übereinstimmung mit dem Steckverbinder C96 gewählt werden. Es ist nur eine weitere Reihe von Löchern vorgesehen, die näher am Rand der Leiterplatte liegt.The object is achieved according to the invention in that the points of curvature are exposed in the recess, that the distance of the row of connecting pins adjacent to the edge at the ends of the connecting pins from the edge is less than 5 mm and that the flanges are each at two points which are transverse to the Longitudinal axis of the insulating body are arranged side by side, are connected to the printed circuit board via fastening means. A connector with the design described above requires no more than four pitches of 5.08 mm in the direction perpendicular to the plane of the circuit board. Such an installation division is provided for subracks according to DIN 41 494 for assemblies or their front panels. In addition, the hole pattern for three rows of pins can be selected on the circuit board in accordance with the connector C96. There is only another row of holes that is closer to the edge of the circuit board.

Es ist günstig, wenn die Messerleiste so ausgebildet ist, dass sie nicht nur an zwei Stellen mit der Leiterplatte verbunden ist. Vorzugsweise springen an den stirnseitigen Enden des Isolierkörpers der Messerleiste Flansche vor, die je an zwei Stellen, die quer zur Längsachse des Isolierkörpers im Abstand nebeneinander angeordnet sind, über Befestigungsmittel mit der Leiterplatte verbunden sind. Die Messerleiste ist also an vier Stellen an der Leiterplatte befestigbar. Damit lassen sich die Andrückkräfte grossflächiger verteilen, so dass eine wesentlich stärkere Verbindung zwischen Messerleiste und Leiterplatte erzielt wird. Eine höhere und gleichmässiger auf die Messerleiste einwirkende Verbindungskraft ist vorteilhaft, weil durch die grössere Anzahl von Messerkontakten höhere Steck- und Ziehkräfte auftreten. Diese höheren Steck- und Ziehkräfte lassen sich mit der vorstehend beschriebenen Anordnung besser beherrschen. Dies bedeutet, daß beim Zusammenfügen und Trennen von Messer- und Federleisten die Teile genauer geführt werden, d. h. Verschiebungen der Messerund Federleistengehäuse aus ihrer Sollposition bzw. Verkantungen dieser Teile sind relativ gering. Geringe Verschiebungen bzw. Verkantungen behindern das Zusammenfügen und Trennen der Steckverbinderteile nicht.It is advantageous if the male connector is designed in such a way that it is not only connected to the printed circuit board at two points. Flanges preferably protrude at the front ends of the insulating body of the male connector, each of which is connected to the printed circuit board by means of fastening means at two locations which are spaced apart transversely to the longitudinal axis of the insulating body. The male connector can therefore be attached to the circuit board in four places. The pressure forces can thus be distributed over a large area, so that a much stronger connection between the male connector and the printed circuit board is achieved. A higher and more uniform connecting force acting on the male connector is advantageous because the larger number of male contacts results in higher insertion and pulling forces. These higher insertion and pulling forces can be mastered better with the arrangement described above. This means that when assembling and separating knife and female connectors, the parts are guided more precisely, ie displacements of the knife and female connector housings from their desired position or tilting of these parts are relatively small. Slight displacements or canting do not hinder the joining and separating of the connector parts.

Eine Möglichkeit zur Erhöhung der Verbindungskräfte insbesondere bei Steck- und Ziehmaßnahmen ist die Anordnung eines Befestigungslochs für Schrauben und eines Zapfens, der in eine Leiterplattenausnehmung ragt, an jedem Flansch des Messerleistengehäuses. Eine solche Verbindung läßt sich rascher herstellen. Es können auch zwei Befestigungslöcher je Flansch vorgesehen werden, die eine besonders feste Verbindung mit Hilfe von Schrauben über entsprechende Löcher in der Leiterplatte zulassen. Auch die Federleisten weisen zweckmäßigerweise je zwei stirnseitige Flansche mit mindestens zwei Befestigungslöchern auf. Hierdurch sind Schraubverbindungen an vier Stellen zwischen Federleisten und Tragelementen möglich, d. h. auch die Federleisten sind für die Beherrschung größerer Steck- und Ziehkräfte auf einfache Weise ausgelegt.One possibility for increasing the connecting forces, in particular in the case of plug-in and pulling measures, is to arrange a fastening hole for screws and a pin, which projects into a circuit board recess, on each flange of the male connector housing. Such a connection can be established more quickly. Two mounting holes per flange can also be provided, which allow a particularly firm connection with the aid of screws via corresponding holes in the printed circuit board. The female connectors also expediently each have two end flanges with at least two fastening holes. This allows screw connections at four locations between female connectors and support elements, d. H. the female connectors are also designed for mastering large plug-in and pulling forces in a simple manner.

Von großer Bedeutung ist auch noch der Abstand von etwa 2,76 mm zwischen dem Leiterplattenrand und der ersten Reihe von Enden der Anschlußstifte. Die oben beschriebene Vorrichtung läßt einen solchen Abstand zu. Damit steht auf der Leiterplatte ein größerer Raum für Leiterbahnen und elektrische bzw. elektronische Bauelemente zur Verfügung.The distance of about 2.76 mm between the edge of the circuit board and the first row of ends of the connecting pins is also of great importance. The device described above allows such a distance. This means that there is a larger space on the circuit board for conductor tracks and electrical or electronic components.

Die Erfindung wird im folgenden an Hand eines in einer Zeichnung dargestellten Ausführungsbeispiels näher erläutert, aus dem sich weitere Merkmale sowie Vorteile ergeben.The invention is explained in more detail below with reference to an embodiment shown in a drawing, from which further features and advantages result.

Die in Figur 1 dargestellten Steckverbinder sind jeweils als Messerleiste 1 und als Federleiste 2 ausgebildet. Die Messerleiste 1 weist einen Isolierkörper 3 auf, der eine quaderförmige Aussparung 4 enthält, in deren Längsrichtung parallel zueinander vier Reihen von Messerkontakten 5 in gleichmäßigem Abstand voneinander angeordnet sind. Die Messerkontakte 5 haben einen gegenseitigen Abstand von 2,54 mm. Die Reihen der Messerkontakte 5 sind 2,54 mm voneinander entfernt. Die Messekontakte 5 gehen in Anschlußstifte 6 über, die mit dem Isolierkörper 3 verbunden sind. Beispielsweise sind die Anschlußstifte 6 in den Isolierkörper 3 eingegossen. Die Enden 7 der Anschlußstifte 6 sind um 90° abgewinkelt und laufen senkrecht zur Ebene 8 einer Leiterplatte 9. Die Leiterplatte 9 enthält nicht näher bezeichnete Löcher, in die die Enden 7 eingesteckt sind.The connectors shown in Figure 1 are each designed as male connector 1 and female connector 2. The male connector 1 has an insulating body 3, which contains a cuboid recess 4, in the longitudinal direction of which four rows of male contacts 5 are arranged at a uniform distance from one another in parallel. The knife contacts 5 have a mutual distance of 2.54 mm. The rows of knife contacts 5 are 2.54 mm apart. The measuring contacts 5 merge into connecting pins 6, which are connected to the insulating body 3. For example, the connecting pins 6 are cast into the insulating body 3. The ends 7 of the connecting pins 6 are angled by 90 ° and run perpendicular to the plane 8 of a printed circuit board 9. The printed circuit board 9 contains holes, not specified, into which the ends 7 are inserted.

Die Enden 7 sind in parallelen Reihen mit Abständen von 2,54 mm zueinander und zwischen den Reihen angeordnet. Der Abstand der dem Rand 10 der Leiterplatte 9 am nächsten angeordneten Reihe von Enden 7 beträgt etwa 2,76 mm. Die Anschlußstifte 6, die in der dem Rand 7 am nächsten liegenden Reihe angeordnet sind, haben Krümmungsstellen 11, die im Bereich des Isolierkörpers 3 liegen. An den Krümmungsstellen 11 weist der Isolierkörper 3 Aussparungen 12 auf. Die Krümmungsstellen 11 liegen daher frei, so daß eine gewisse Beweglichkeit der Enden vor dem Verlöten mit der Leiterplatte 9 vorhanden ist. Damit können Toleranzen zwischen der Messerleiste 1 und den Löchern der Leiterplatte 9 ausgeglichen werden. Jede Reihe enthält 32 Messerkontakte 5. Die Messerleiste 1 weist daher insgesamt 128 Messerkontakte 5 auf.The ends 7 are arranged in parallel rows at intervals of 2.54 mm from one another and between the rows. The distance between the row of ends 7 closest to the edge 10 of the printed circuit board 9 is approximately 2.76 mm. The connecting pins 6, which are arranged in the row closest to the edge 7, have points of curvature 11 which lie in the region of the insulating body 3. At the points of curvature 11, the insulating body 3 has cutouts 12. The points of curvature 11 are therefore free, so that there is a certain mobility of the ends before soldering to the printed circuit board 9. Tolerances between the male connector 1 and the holes in the printed circuit board 9 can thus be compensated for. Each row contains 32 blade contacts 5. The blade strip 1 therefore has a total of 128 blade contacts 5.

In Figur 2 sind zwei Baugruppen 13, 14 nebeneinander in einem Baugruppenträger dargestellt, der Seitenwände 15 enthält, die über Profilschienen 16 miteinander verbunden sind. Jede Baugruppe enthält eine Leiterplatte 9. An der Leiterplatte der Baugruppe 13 ist eine Messerleiste 1 befestigt, die in eine Federleiste 2 eingesteckt wird, die an der rückwärtigen Platte 17 des Baugruppenträgers befestigt ist. Die Baugruppe 14 enthält einen 96poligen Steckverbinder 18. An den Leiterplatten 9 sind Frontplatten 19 befestigt, die jeweils vier Rasterteilungen T von jeweils 5,08 mm in Längsrichtung der Profilschienen 16 beanspruchen. In Figur 2 sind die vier Rasterteilungen dargestellt, die mit T bezeichnet sind. Die Rasterteilungen T beginnen an der Kante 20 der Seitenwand 15. Der Beginn der Rasterteilungen trägt die Bezeichnungen y, a, c und e. Die Anschlußstifte der Federleiste 2 sind in einer Rasterteilung angeordnet, deren kleinste Einheit in Figur 2 mit t bezeichnet ist und 2,54 mm beträgt. Die Rasterteilung beginnt ebenfalls an der Kante y. Da die Unterteilung des Rasters an der Platte 17 die Hälfte desjenigen an der Frontplatte beträgt, sind die einzelnen Rasterpositionen mit a, b, c, d, e und f bezeichnet.In Figure 2, two assemblies 13, 14 are shown side by side in a rack that contains side walls 15 which are connected to each other via rails 16. Each assembly contains a printed circuit board 9. On the printed circuit board of assembly 13, a male connector 1 is fastened, which is inserted into a female connector 2, which is attached to the rear panel 17 of the subrack. The assembly 14 contains a 96-pin connector 18. Front plates 19 are fastened to the printed circuit boards 9, each of which requires four grid divisions T of 5.08 mm in the longitudinal direction of the profile rails 16. In Figure 2, the four grid divisions are shown, which are denoted by T. The grid divisions T begin at the edge 20 of the side wall 15. The beginning of the grid divisions is labeled y, a, c and e. The connection pins of the female connector 2 are arranged in a grid pitch, the smallest unit of which is designated t in FIG. 2 and is 2.54 mm. The grid division also begins at edge y. Since the subdivision of the grid on the plate 17 is half that on the front plate, the individual grid positions are labeled a, b, c, d, e and f.

Die Fig. 3 zeigt die Messerleiste 1 in Seitenansicht. An den stirnseitigen Enden 21 und 22 des Isolierkörpers 3 sind jeweils Flansche 23 und 24 vorgesehen. Die Flansche 23 und 24 erstrecken sich seitlich neben den Anschlußstiften 6. Die Auflageflächen der Flansche erstrecken sich in Ebenen, die senkrecht zu den Längsachsen der Messerleisten 5 verlaufen. In jedem Flansch 23, 24 befinden sich zwei Befestigungslöcher 25, 26, deren Mittelachsen 27 parallel zu den abgewinkelten Enden 7 der Anschlußstifte 6 verlaufen. Die Mittelachsen 27 der beiden in einem Flansch 23 bzw. 24 angeordneten Befestigungslöcher 25, 26 liegen in einer Ebene, die parallel zu den Ebenen verläuft, in denen die Anschlußstifte 6 mit den abgewinkelten Enden 7 angeordnet sind. Über nicht näher dargestellte, in die Befestigungslöcher 25, 26 eingesetzte Schrauben werden die Messerleisten 1 an den Leiterplatten 9 befestigt. Die Befestigung über je zwei Schrauben an den Flanschen 23, 24 hat den Zweck, die beim Zusammenfügen und Trennen der Steckverbindung auftretenden Kräfte gleichmäßiger auf die Leiterplatte 9 zu übertragen. Durch eine gleichmäßige Kraftübertragung lassen sich Verbiegungen der Leiterplatten und Steck-verbinder vermeiden. Eine starke gleichmäßige Verbindung zwischen Leiterplatten 9 und Messerleisten 1 ist wegen der höheren Steck- und und Ziehkräfte bei größerer Zahl der Messerkontakte 5 notwendig.3 shows the male connector 1 in a side view. At the front ends 21 and 22 of the insulating body 3, flanges 23 and 24 are provided. The flanges 23 and 24 extend laterally next to the connecting pins 6. The contact surfaces of the flanges extend in planes that run perpendicular to the longitudinal axes of the male connectors 5. In each flange 23, 24 there are two fastening holes 25, 26, the central axes 27 of which run parallel to the angled ends 7 of the connecting pins 6. The central axes 27 of the two fastening holes 25, 26 arranged in a flange 23 and 24 lie in a plane which runs parallel to the planes in which the connecting pins 6 with the angled ends 7 are arranged. The male connectors 1 are fastened to the printed circuit boards 9 by means of screws, not shown, inserted into the fastening holes 25, 26. The attachment by means of two screws to the flanges 23, 24 has the purpose of increasing the forces occurring when joining and disconnecting the plug connection to transfer the circuit board 9. Bending of the printed circuit boards and connectors can be avoided by an even power transmission. A strong, even connection between printed circuit boards 9 and male connectors 1 is necessary because of the higher plug-in and pulling forces with a larger number of male contacts 5.

Anstelle eines zweiten Befestigungslochs 25 kann auch ein nicht näher dargestellter Zapfen vorgesehen sein, der vom jeweiligen Flansch 23, 24 in Richtung der Leiterplatte 9 vorspringt, mit der die Messerleiste 1 verbunden ist. Der Zapfen ragt in ein sonst für eine Schraube vorgesehenes Loch. Die Zapfen bewirken ebenfalls insbesondere bei Steck- und Ziehmaßnahmen eine gleichmäßigere Kraftübertragung zwischen Messerleiste 1 und Leiterplatte 9.Instead of a second fastening hole 25, a pin (not shown in more detail) can also be provided, which projects from the respective flange 23, 24 in the direction of the printed circuit board 9 to which the male connector 1 is connected. The pin protrudes into a hole otherwise provided for a screw. The pegs also bring about a more uniform power transmission between the male connector 1 and the printed circuit board 9, particularly in the case of plugging and pulling measures.

Die Federleiste 2, die in den Fig. 4 und 5 detaillierter dargestellt ist, enthält ein Isoliergehäuse 28, von dessen schmalen Stirnseiten 29 jeweils ein Flansch 30 vorspringt, der sich mindestens über die Breite der gesamten Stirnseite 29 erstreckt. Im Flansch 30 befinden sich nebeneinander zwei Befestigungslöcher 31, 32, deren Mittelachsen 33 parallel zu Stiften 34 verlaufen, die mit den nicht näher bezeichneten Federkontakten verbunden sind und über das Isoliergehäuse 28 hinausragen. Die Mittelachsen 33 liegen in Ebenen, die parallel zu den Stirnseiten 29 verlaufen. Mittels der Befestigungslöcher 31, 32 werden die Federleisten durch vier Schrauben an der jeweiligen Platte 17 angeschraubt. Damit ist eine stärkere und gleichmäßigere Verbindung zwischen Platte 17 und Federleiste 2 geschaffen, die für die höheren Steck- und Ziehkräfte aufgrund der größeren Federkontaktzahl besonders geeignet ist.The female connector 2, which is shown in more detail in FIGS. 4 and 5, contains an insulating housing 28, from the narrow end faces 29 of which a flange 30 projects, which extends at least over the width of the entire end face 29. In the flange 30 there are two fastening holes 31, 32 next to one another, the central axes 33 of which run parallel to pins 34 which are connected to the spring contacts (not designated in any more detail) and protrude beyond the insulating housing 28. The central axes 33 lie in planes that run parallel to the end faces 29. By means of the fastening holes 31, 32, the female connectors are screwed to the respective plate 17 by four screws. This creates a stronger and more uniform connection between plate 17 and female connector 2, which is particularly suitable for the higher plug-in and pulling forces due to the larger number of spring contacts.

Die Befestigungslöcher 25, 26 bzw. ein Befestigungsloch 26 und ein Zapfen sowie die Befestigungslöcher 31, 32 sind im Raster von 2.54 mm angeordnet.The mounting holes 25, 26 or a mounting hole 26 and a pin and the mounting holes 31, 32 are arranged in a 2.54 mm grid.

In den Flanschen 30 sind oberhalb der Bohrungen 30, 31 jeweils breitere Ausnehmungen 35 vorhanden, deren Abmessungen an die Abmessungen von nicht dargestellten Muttern oder Schraubenköpfe so angepaßt sind, daß die Muttern oder Schraubenköpfe unverdrehbar in den Ausnehmungen 35 gehalten werden.In the flanges 30 above the bores 30, 31 there are wider recesses 35, the dimensions of which are adapted to the dimensions of nuts or screw heads, not shown, such that the nuts or screw heads cannot be rotated are held in the recesses 35.
