Die vorliegende Erfindung betrifft eine in eine Leiterplatte einpreßbare Stiftleiste gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a pin strip that can be pressed into a printed circuit board the preamble of claim 1.

Die Kontaktstifte derartiger, aus der DE 38 10 471 A1 bekannten Stiftleisten bestehen aus Kostengründen überwiegend aus gebogenem Draht.The contact pins of such pin strips known from DE 38 10 471 A1 consist of For cost reasons, mostly from bent wire.

Durch die querschnittsbedingt geringe Befestigkeit dieser Kontaktstifte können sich Probleme beim Einpressen in die Leiterplatte ergeben, da die Krafteinleitung hierbei außerhalb der jeweiligen Kontaktstiftachse liegt, wodurch ein die Lage der Kontaktstifte im Gehäuse veränderndes Kippmoment erzeugt wird.Problems can arise due to the low fastening of these contact pins due to their cross section when pressed into the circuit board because the force is applied outside of the respective pin axis, whereby the position of the pins in Housing changing tilting moment is generated.

Neben dieser, die Funktionsfähigkeit der Kontaktstifte beeinträchtigenden möglichen Lageveränderung kann es durch die beim Einpreßvorgang sehr hohen, auf die Kontaktstifte und das Gehäuse einwirkenden Einpreßkräfte zu Beschädigungen und Verformungen des Gehäuses, der Kontaktstifte und der Leiterplatte kommen.In addition to this, the possible impairment of the functionality of the contact pins The change in position can be caused by the very high pressure on the contact pins and the pressing forces acting on the housing for damage and deformation of the housing, the contact pins and the circuit board.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Stiftleiste der gattungsgemäßen Art so zu gestalten, daß eine Lageveränderung der Kontaktstifte und deren Beschädigung bwz. Verformung durch die beim Einpressen in die Leiterplatte auftretenden Kräfte ausgeschlossen wird.The present invention is therefore based on the object of a pin header of the generic type Art to design so that a change in position of the contact pins and their damage bwz. Deformation caused by pressing into the circuit board occurring forces is excluded.

Diese Aufgabe wird durch eine Stiftleiste gelöst, die die Merkmale des Anspruches 1 aufweist.This object is achieved by a pin header, which has the features of claim 1 having.

Durch diese konstruktive Ausgestaltung der Stiftleiste werden die Kontaktstifte praktisch eingespannt, so daß die beim Einpressen auftretenden, auf die Kontaktstifte einwirkenden Kräfte von dem Halteteil bzw. dem Gehäuse aufgenommen werden.This design of the pin header makes the contact pins practical clamped so that those occurring during the pressing in on the contact pins acting forces are absorbed by the holding part or the housing.

Die Kontaktstifte können dabei glattschäftig ausgebildet sein, so ohne mit dem Gehäuse und/oder dem Halteteil einen Formschluß bildende Haltekonturen. Hierdurch ist eine sehr preiswerte Herstellung und Montage möglich.The contact pins can be smooth, so without the housing and / or the holding part forming a positive locking contours. hereby very inexpensive manufacture and assembly is possible.

Im Herstellungsverlauf der Stiftleiste werden zunächst die Kontaktstifte im Gehäuse positioniert. Anschließend erfolgt das Einsetzen des Halteteiles und dessen Befestigung.During the manufacturing process of the pin header, the contact pins are first in the housing positioned. Then the holding part is inserted and fastened.

Hierzu sind verschiedene Möglichkeiten denkbar, so kann das Halteteil beispielsweise mit dem Gehäuse verrastet, verklebt oder verschweißt sein.Various possibilities are conceivable for this, for example the holding part be locked, glued or welded to the housing.

Eine besonders einfache Montage ergibt sich dann, wenn das Halteteil formschlüssig in das Gehäuse eingreift und dort verrastet.A particularly simple assembly results when the holding part is form-fitting engages in the housing and locked there.

Weiter besteht die Möglichkeit, auch für Stiftleisten mit mehrreihigen Kontaktstiften lediglich ein Halteteil vorzusehen, um sämtliche Kontaktstifte entsprechend zu fixieren.There is also the possibility for pin headers with multi-row contact pins to provide only one holding part in order to fix all contact pins accordingly.

Die Anordnung des Halteteiles richtet sich dabei jeweils nach den konstruktiven Notwendigkeiten, wobei das Halteteil beispielsweise von oben, von unten oder von der Seite eingesetzt werden kann.The arrangement of the holding part depends on the design requirements, the holding part, for example from above, from below or from the Side can be used.

In den Fig. 1 und 2 ist eine Stiftleiste dargestellt, die ein Gehäuse aufweist, in das aus Draht gebogene Kontaktstifte 3 eingelegt sind.1 and 2, a pin header is shown which has a housing in which Contact pins 3 bent from wire are inserted.

Im Bereich jedes Kontaktstiftes 3 sind in dem Gehäuse 1 Stecknuten 4 eingeformt, die so geöffnet sind, daß ein bequemes Einlegen der Kontaktstifte 3 möglich ist.In the area of each contact pin 3, 1 grooves 4 are formed in the housing, which are opened so that a comfortable insertion of the contact pins 3 is possible.

Zur Fixierung und zum Einspannen der Kontaktstifte 3 ist ein Halteteil 2 vorgesehen, daß im Ausführungsbeispiel nach den Fig. 1 und 2 durch eine Steckleiste gebildet wird, die aus einer Deckleiste 7 und daran angeordneten Haltezapfen 5 besteht.A holding part 2 is provided for fixing and clamping the contact pins 3, that in the embodiment of FIGS. 1 and 2 is formed by a header , which consists of a cover strip 7 and holding pin 5 arranged thereon.

Das Halteteil 2 ist formschlüssig in das Gehäuse 1 eingesteckt, wobei die Haltezapfen 5 in den Stecknuten 4 einliegen und in ihren Querschnittskonturen und -abmaßen denen der Stecknuten 4 entsprechen.The holding part 2 is positively inserted into the housing 1, the holding pin 5 lie in the slots 4 and in their cross-sectional contours and dimensions correspond to those of the slots 4.

Weiter ist jeder Haltezapfen 5 mit einem Anschlag 6 versehen, der an dem zugeordneten Kontaktstift 3 ebenso anliegt, wie der Haltezapfen 5 im übrigen.Furthermore, each holding pin 5 is provided with a stop 6, which on the associated Contact pin 3 bears as well as the retaining pin 5 in the rest.

Das Gehäuse 1 ist im Einfügebereich des Kontaktstiftes 3 so ausgeformt, daß dieser in dem abgewinkelten und den angrenzenden Bereichen ebenso wie von dem Haltezapfen 5 bzw. dem Anschlag 6 weitgehend anliegend spielfrei umschlossen wird.The housing 1 is shaped in the insertion area of the contact pin 3 so that it in the angled and adjacent areas as well as from the retaining pin 5 or the stop 6 is enclosed largely free of play.

Dadurch werden die beim Einpressen der Stiftleiste in eine nicht dargestellte Leiterplatte auftretenden, auf die Kontaktstifte 3 einwirkenden Einpreßkräfte von dem Halteteil 2 und dem Gehäuse 1 so weit aufgenommen, daß eine Lageveränderung und/oder Beschädigung oder Verformung der Kontaktstifte 3 ausgeschlossen ist.As a result, when the pin strip is pressed into a circuit board (not shown) occurring, acting on the contact pins 3 pressing forces from the holding part 2 and the housing 1 added so far that a change in position and / or damage or deformation of the contact pins 3 is excluded.

In den Fig. 3 bis 7 sind weitere Ausführungsbeispiele von Stiftleisten gezeigt, bei denen die Halteteile 2 jeweils unterschiedlich ausgebildet sind.3 to 7 show further exemplary embodiments of pin strips, at which the holding parts 2 are each designed differently.

So ist das in der Fig. 3 erkennbare Halteteil 2 so ausgebildet, daß es Durchgangsöffnungen 9 aufweist, die von den abgewinkelten Kontaktstiften 3 beim Einfügen durchtreten werden und in die eine seitliche Abstützung gewährleistet ist.The holding part 2 which can be seen in FIG. 3 is designed such that it has through openings 9, which pass through the angled contact pins 3 when inserting and in which a lateral support is guaranteed.

Der abgewinkelte Schenkel des Kontaktstiftes 3 liegt dabei mit seinem Rücken an dem Gehäuse 1 an. The angled leg of the contact pin 3 lies with his back the housing 1.

Bei der Stiftleiste der Fig. 4 besteht das Halteteil 2 aus einer Platte, die eine rückseitige Abstützung für die Kontaktstifte 3 bildet und die durch Verkleben oder Verschweißen mit dem Gehäuse 1 verbunden sein kann.4, the holding part 2 consists of a plate that has a rear Support for the contact pins 3 and forms by gluing or welding can be connected to the housing 1.

In der Fig. 5 ist eine Stiftleiste erkennbar, die eine Doppelreihe von Kontaktstiften 3 aufweist. Dabei ist das Halteteil 2 so gestaltet, daß Öffnungen 9 vorgesehen sind, in die beim Einsetzen des Halteteiles 2 die nebeneinander liegenden Kontaktstifte 3 eingesteckt werden.A pin strip can be seen in FIG. 5, which has a double row of contact pins 3 having. The holding part 2 is designed so that openings 9 are provided in the contact pins 3 lying next to one another when the holding part 2 is inserted be plugged in.

Auch hier bildet das Halteteil 2 zusammen mit dem Gehäuse 1 eine im Biegebereich der Kontaktstifte 3 wirksame Abstützung. Die Einfügerichtung des Halteteiles 2 und die Achsrichtung der in die Leiterplatte einzupreßenden Schenkel der Kontaktstifte 3 sind dabei gleich.Here, too, the holding part 2, together with the housing 1, forms one in the bending region the contact pins 3 effective support. The insertion direction of the holding part 2 and the axial direction of the legs of the contact pins 3 to be pressed into the printed circuit board are the same.

Eine weitere Variante der Erfindung ist in der Fig. 6 gezeigt, wobei die Kontaktstifte 3 Z-förmig ausgebildet sind und das Gehäuse im Bereich der Anlage der Kontaktstifte 3 im weitesten Sinn eine Halbschale bildet, in der die Kontaktstifte einliegen, während das Halteteil 2 die andere Hälfte der Halbschale darstellen, die die Kontaktstifte 3 oberhalb und seitlich entsprechend abstützt.A further variant of the invention is shown in FIG. 6, the contact pins 3 Z-shaped and the housing in the area of the contact of the contact pins 3rd in the broadest sense forms a half-shell in which the contact pins lie while the holding part 2 represents the other half of the half-shell, which the contact pins 3rd supported above and laterally.

Das in der Fig. 7 gezeigte Beispiel einer Stiftleiste, das ebenso wie das in der Fig. 5 dargestellte eine Doppelreihe von Kontaktstiften 3 aufweist, ist ähnlich ausgebildet, wie das in der Fig. 5.The example of a pin strip shown in FIG. 7, which, like that in FIG. 5 has a double row of contact pins 3, is of similar design, like that in FIG. 5.

In jedem Fall ist ein sicherer Halt der Kontaktstifte gewährleistet, die vor allem deshalb von großer Bedeutung ist, weil, wie sämtliche Ausführungsbeispiele zeigen, die Kontaktstifte mit ihrem Einpreßende außermittig aus der Stiftleiste ragen, so daß eine, beispielsweise durch einen Einpreßstempel, aufgebrachte Einpreßkraft exzentrisch an die Kontaktstifte 3 angreift.In any case, a secure hold of the contact pins is guaranteed, mainly because of this is of great importance because, as all the exemplary embodiments show, the Protruding contact pins with their press-in end off-center from the pin strip, so that an eccentric, for example, by a press-in force attacks on the contact pins 3.

Das Halteteil 2 und das Gehäuse 1 sind in ihrer Form so gehalten, daß sie ein etwa quaderförmiges Gebilde mit einer flachen Einpreßfläche ergeben, was die Handhabung der Stiftleiste vereinfacht. The holding part 2 and the housing 1 are held in their shape so that they are about cuboidal structure with a flat press-in surface result in handling the pin header simplified.
