Abstract

The connecting elements (3) which lead from a plug connector strip (1) to the printed circuit board are intended to be bent obliquely in some cases. For this purpose, the free ends are initially bent through an angle of less than 90 DEG , and all of the part of the connecting element (3) projecting out of the plug connector strip (1) is then bent until the free ends run at right angles to the printed circuit board. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Abbiegen von An­ schlußelementen, welche in Aufnahmekammern einer elektrischen Steckverbinderleiste gehaltene Kontaktelemente mit der Leiterplatte einer elektrischen Baugruppe verbinden.The invention relates to a method for turning An closing elements, which in the receiving chambers of an electrical Connector strip held contact elements with the Connect the circuit board of an electrical assembly.

Aus dem deutschen Gebrauchsmuster 84 28 343 ist eine elektri­ sche Steckverbinderleiste bekannt, bei der die von der Leiterplatte am weitesten entfernten Reihen von Anschluß­ elementen bereits innerhalb der Aufnahmekammern für die Kontaktelemente schräg zur Leiterplatte hin abgewinkelt sind. Durch die Abbiegung innerhalb der Kammer insbesondere bei den äußeren Anschlußelementen werden die Kriechstrecken und der Abstand des Anschlußelementes zu benachbarten Bau­ gruppen vergrößert. Aufgabe der vorliegenden Erfindung ist es, für eine derartige Steckverbinderleiste ein geeignetes Verfahren zum Abbiegen der schräg verlaufenden Anschluß­ elemente anzugeben.From the German utility model 84 28 343 is an electri cal connector strip known in which the of the PCB most distant rows of connector elements already within the admission chambers for the Contact elements angled at an angle to the circuit board are. By turning inside the chamber in particular the creepage distances for the outer connection elements and the distance of the connecting element to neighboring construction groups enlarged. The object of the present invention is it, a suitable for such a connector strip Procedure for turning the sloping connector specify elements.

Diese Aufgabe wird dadurch gelöst, daß zuerst die Enden der aus den Aufnahmekammern herausragenden Abschnitte der parallel zur Leiterplattenebene verlaufenden Anschlußelemente um einen Winkel von kleiner 90° abgebogen werden, und daß in einem zweiten Biegevorgang der gesamte aus der Aufnahmekammer herausragende Abschnitt des Anschlußelements um eine Biege­ stelle im Endbereich der Aufnahmekammer soweit abgebogen wird, daß sich die Enden der Anschlußelemente genau senkrecht zur Leiterplattenebene befinden.This object is achieved in that the ends of the sections of the parallel protruding from the receiving chambers to the circuit board level connecting elements by one Angles of less than 90 ° are bent, and that in one second bending process the entire from the receiving chamber protruding portion of the connector around a bend in the end area of the receiving chamber bent so far is that the ends of the connection elements are exactly vertical to the PCB level.

Das erfindungsgemäße Verfahren zum Abbiegen zeichnet sich durch eine einfache Vorgehensweise aus und ermöglicht so eine rationelle Fertigung von Steckverbinderleisten mit abgebogenen Anschlußelementen.The method according to the invention for turning stands out through a simple procedure and thus enables  a rational production of connector strips with bent connecting elements.

Eine Weiterbildung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, daß der erste Biegevorgang mittels eines drehbaren Biegestempels um eine von unten angreifende Matrize erfolgt, wobei der nicht umzubiegende Teil von einem Niederhalter in seiner urprünglichen Lage fixiert wird, und daß der zweite Biegevorgang nach Entfernung der Matrize mittels des Niederhalters um die im Endbereich der Aufnahme­ kammer definierte Biegestelle erfolgt. Auf diese Weise ist gewährleistet, daß die Biegevorgänge nur ein Minimum an unter­ schiedlichen Werkzeugen erfordern.A further development of the method according to the invention is characterized in that the first bending process by means of of a rotatable bending punch around a one attacking from below The die is made with the part of a hold-down is fixed in its original position, and that the second bending process after removal of the die by means of the hold-down device in the end area of the holder Chamber defined bending point takes place. That way ensures that the bends are kept to a minimum require different tools.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.In the following the invention based on one in the drawing illustrated embodiment explained in more detail.

Die Figur zeigt einen schematischen Querschnitt durch eine Steckverbinderleiste 1, die mit Anschlußelementen 3 bestückt ist. Die Anschlußelemente 3 verbinden die in Aufnahmekammern der Steckverbinderleiste gehaltenen Kontaktelemente 2 mit der Leiterplatte einer elektrischen Baugruppe, die hier nicht dargestellt ist.The figure shows a schematic cross section through a connector strip 1 , which is equipped with connection elements 3 . The connection elements 3 connect the contact elements 2 held in the receiving chambers of the connector strip to the circuit board of an electrical assembly, which is not shown here.

Es soll nun kurz der Biegevorgang zum Abbiegen der Anschluß­ elemente erläutert werden. Zuerst wird mittels eines dreh­ baren Biegestempels 4 ein der Länge nach vorgegebener End­ bereich eines Anschlußelementes um eine von unten angreifende verschiebbare Matrize 6 um einen definierten Winkel, der kleiner als 90° ist, abgebogen. Während dieses ersten Biege­ vorgangs wird der Teil des Anschlußelementes, der aus der Steckverbinderleiste herausragt und noch nicht abgebogen werden soll, durch einen Niederhalter 5 in seiner ursprüng­ lichen Lage fixiert. Nach dem ersten Biegevorgang taucht die Matrize 6 nach unten, und der Niederhalter 5 biegt das gesamte aus der Steckverbinderleiste ragende Anschlußelement um eine Biegestelle im Endbereich der Aufnahmekammer frei in die endgültige Sollage, die in der Figur gestrichelt angegeben ist.The bending process for bending the connecting elements will now be briefly explained. First, by means of a rotatable bending punch 4, a lengthwise predetermined end area of a connecting element is bent by a movable die 6 engaging from below by a defined angle, which is less than 90 °. During this first bending process, the part of the connecting element which protrudes from the connector strip and is not yet to be bent is fixed in its original position by a holding-down device 5 . After the first bending process, the die 6 dips down, and the hold-down 5 bends the entire connecting element protruding from the connector strip by a bending point in the end region of the receiving chamber into the final desired position, which is indicated by dashed lines in the figure.
