Description

Die Erfindung betrifft eine elektrische Steckverbinderleiste, die mit mehreren Reihen von Kontaktelementen versehen ist, die mittels Anschlußelementen mit einer Leiterplatte einer elektrischen Baugruppe verbunden sind, wobei die aus Aufnahmekammem für die Kontaktelemente herausragenden Abschnitte der Anschlußelemente zur Leiterplatte hin abgebogen sind, und wobei die Steckverbinderleiste an ihrer Rückseite mehrere Flansche mit nach unten gerichteten Einpreßzapfen aufweist.The invention relates to an electrical connector strip which is provided with a plurality of rows of contact elements which are connected by means of connection elements to a printed circuit board of an electrical assembly, the portions of the connection elements projecting from the receiving chambers for the contact elements being bent toward the circuit board, and the connector strip being attached its rear has several flanges with downward facing press-in pins.

Eine derartige Steckverbinderleiste ist zum Beispiel aus der DE-A 29 25 590 bekannt. Diese bekannte Steckverbinderleiste hat wenigstens zwei in entsprechende Öffnungen der gedruckten Schaltung einführbare Einpreßzapfen. Bei der Verwendung mehrerer Einpreßzapfen, deren Verwendung aus Festigkeitsgründen erwünscht ist, tritt das Problem auf, daß sowohl die Leiterplatte als auch die Steckverbinderleiste so gefertigt sein müssen, daß wegen der Einpreßzapfen eine sehr hohe Toleranz erreicht werden muß. Dies führt zu sehr teuren Herstellungsverfahren.Such a connector strip is known for example from DE-A 29 25 590. This known connector strip has at least two press-in pins which can be inserted into corresponding openings in the printed circuit. When using several press-in pins, the use of which is desirable for reasons of strength, the problem arises that both the printed circuit board and the connector strip must be manufactured in such a way that a very high tolerance must be achieved because of the press-in pins. This leads to very expensive manufacturing processes.

Aufgabe der Erfindung ist es, eine Steckverbinderleiste der obengenannten Art anzugeben, welche für den Zusammenbau mit einer Leiterplatte nicht unbedingt höchste Toleranzansprüche erfüllen muß.The object of the invention is to provide a connector strip of the type mentioned above, which does not necessarily have to meet the highest tolerance requirements for assembly with a printed circuit board.

Diese Aufgabe wird erfindungsgemäß für eine elektrische Steckverbinderleiste der eingangs genannten Art dadurch gelöst, daß gegenüber jedem dem Leistenkörper direkt benachbarten Einpreßzapfen am Leistenkörper eine einen dreieckigen Querschnitt aufweisende Quetschrippe, deren Querschnitt sich in Richtung zur Unterseite des Flansches vergrößert ist, gebildet ist.This object is achieved according to the invention for an electrical connector strip of the type mentioned at the outset in that a squeezing rib having a triangular cross section, the cross section of which is enlarged in the direction of the underside of the flange, is formed on each molding pin directly adjacent to the strip body.

Dadurch wird ein Toleranzausgleich zwischen dem eigentlichen Körper der Steckverbinderleiste und der Leiterplatte geschaffen. Gleichzeitig wird die Einpreßkraft dabei auch auf den Steckverbinderleistenkörper übertragen und von diesem mitaufgefangen.This creates a tolerance compensation between the actual body of the connector strip and the circuit board. At the same time, the press-in force is also transmitted to the connector body and is also absorbed by it.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Die Zeichnung zeigt einen Querschnitt durch einen Flansch 6 einer Steckverbinderleiste 1, sowie den dazugehörigen Querschnitt durch eine Leiterplatte 2. Dabei ist der größte Teil des Steckverbinderleistenkörpers zur Vereinfachung der Darstellung als Draufsicht dargestellt.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing. The drawing shows a cross section through a flange 6 of a connector strip 1, and the associated cross section through a printed circuit board 2. The majority of the connector strip body is shown as a plan view to simplify the illustration.

Die einstückigen Kontaktelemente bestehend aus Kontaktfedern und Anschlußelementen, die in Kammern der Steckverbinderleiste gehalten sind und den Kontakt zur Leiterplatte herstellen, sind in der Zeichnung nicht dargestellt, da sie nicht erfindungswesentlich sind. Wie eingangs erwähnt, besteht die Aufgabe darin, die Steckverbinderleiste 1 mit der Leiterplatte 2 fest zu verbinden. Dazu weist die Steckverbinderleiste 1 mehrere beliebig verteilte Flansche 6 auf, die mit Einpreßzapfen 3 versehen sind. Beim dargestellten Ausführungsbeispiel sind pro Flansch zwei Einpreßzapfen vorgesehen. Dabei ist, wie der Zeichnung zu entnehmen ist, der der Steckverbinderleiste 1 unmittelbar benachbarte Einpreßzapfen 3 stärker dimensioniert. Dieser Einpreßzapfen 3 weist einen größeren Durchmesser und. eine größere Länge auf. Dadurch wird eine gewisse Vorführung erreicht. Da während des Einpreßvorganges erhebliche Kräfte, besonders am Anfang auftreten können, ist der die Vorführung übernehmende Einpreßzapfen stärker dimensioniert. Der zweite Einpreßzapfen dient hauptsächlich einer endgültigen Fixierung der Steckverbinderleiste in bezug auf die Leiterplatte 2. Die zur Aufnahme der Einpreßzapfen 3 notwendigen Bohrungen in der Leiterplatte 2 sind mit dem Bezugszeichen 5 gekennzeichnet.The one-piece contact elements consisting of contact springs and connection elements, which are held in chambers of the connector strip and make contact with the circuit board, are not shown in the drawing, since they are not essential to the invention. As mentioned at the beginning, the task is to firmly connect the connector strip 1 to the printed circuit board 2. For this purpose, the connector strip 1 has a plurality of arbitrarily distributed flanges 6, which are provided with press-in pins 3. In the illustrated embodiment, two press-in pins are provided per flange. Here, as can be seen from the drawing, the press-in pin 3 immediately adjacent to the connector strip 1 is of larger dimensions. This press-in pin 3 has a larger diameter and. a greater length. A certain demonstration is thereby achieved. Since considerable forces, particularly at the beginning, can occur during the press-in process, the press-in pin taking over the demonstration is dimensioned to be larger. The second press-in pin mainly serves to finally fix the connector strip with respect to the printed circuit board 2. The holes in the printed circuit board 2 required for receiving the press-in pin 3 are identified by reference number 5.

Aufgrund der vorgegebenen Toleranzen zwischen dem Durchmesser der Einpreßzapfen und dem Durchmesser der Bohrungen 5 können durch einen Überschnitt beim Einpressen Späne entstehen. Diese würden sich zwischen Leiterplatte 2 und der Unterseite des Flansches 6 ablagern und ein planes Aufliegen des Flansches 6 auf der Leiterplatte 2 verhindern. Um dieses zu vermeiden, sind unterhalb der Einpreßzapfen an der Unterseite des Flansches 6 Hohlräume 4 vorgesehen. Diese dienen zur Aufnahme eventuell anfallender Späne. Diese Hohlräume sind zweckmäßigerweise so ausgebildet, daß sie Späne, die über den gesamten Umfang des Einpreßzapfens auftreten, aufnehmen können. Die einfachste Art wäre es, diese Hohlräume als kreisförmige Nuten auszubilden, wobei der Innendurchmesser dieser Nuten dem Durchmesser der Einpreßzapfen 3 entspricht. Die äußere Begrenzung der Hohlräume 4 muß aber durchaus nicht kreisförmig gestaltet sein.Due to the specified tolerances between the diameter of the press-in pins and the diameter of the bores 5, an overcut when pressing in can produce chips. These would deposit between the circuit board 2 and the underside of the flange 6 and prevent the flange 6 from lying flat on the circuit board 2. To avoid this, 6 cavities 4 are provided below the press-in pins on the underside of the flange. These serve to pick up any chips. These cavities are expediently designed so that they can accommodate chips that occur over the entire circumference of the press-in pin. The simplest way would be to design these cavities as circular grooves, the inner diameter of these grooves corresponding to the diameter of the press-in pins 3. The outer boundary of the cavities 4 does not have to be circular.

Um ein festes Anliegen der Leiterplatte 2 an den eigentlichen Körper der Steckverbinderleiste trotz bestehender Toleranzen zu ermöglichen, sind gegenüber jedem dem Leistenkörper direkt benachbarten Einpreßzapfen am Leistenkörper Quetschrippen 7 vorgesehen. Diese Quetschrippen weisen einen dreieckigen Querschnitt auf, der sich zur Unterseite des Flansches 6 hin vergrößert. Neben einem festen Anliegen der Leiterplatte 2 an den Steckverbinderleistenkörper wird gleichzeitig durch die Quetschrippen 7 erreicht, daß die Steckkraft auch auf den Körper der Steckverbinderleiste 1 übertragen wird und von diesem zu einem Teil mit aufgefangen wird.In order to allow the printed circuit board 2 to lie firmly against the actual body of the connector strip despite existing tolerances, crimp ribs 7 are provided on each strip pin directly adjacent to the strip body. These pinch ribs have a triangular cross section, which increases towards the underside of the flange 6. In addition to a firm contact of the printed circuit board 2 with the connector strip body, the pinch ribs 7 at the same time ensure that the plug-in force is also transmitted to the body of the connector strip 1 and is partly absorbed by it.
