Abstract
Description
Die Erfindung betrifft einen elektrischen Einpresskontakt zur Übertragung von elektrischem Strom und/oder Signalen gemäß Gattungsbegriff des Anspruchs 1.The invention relates to an electrical press-fit contact for the transmission of electrical current and / or signals according to the preamble of
Stand der TechnikState of the art
Ein gattungsgemäßer Einpresskontakt ist aus der
Um die Leiterplatte und deren Durchkontaktierung und insbesondere deren Innenleiterbahnen beim Einpressen nicht zu beschädigen ist es sinnvoll, dass der Einpresskontakt elastisch ausgelegt ist, und möglichst mit geringer Kraft auf die Lochwandung drückt. Um dieses zu erreichen, ist eine geringe Normalkraft der an der Lochwandung anliegenden Schenkel der Einpresskontakte anzustreben. Die erforderliche Ausdrückkraft der Einpresskontakte aus der Leiterplattenlochung muss jedoch aus Stabilitätsgründen, insbesondere bei freistehenden Kontakten, relativ hoch sein. Diese qualitätswichtige Forderung ist jedoch bei Leiterplattenendlochdurchmessern unter 1,00 mm und bei Materialdicken der Einpresskontakte unter 0,60 mm nicht erreichbar, insbesondere wenn die Normalkraft der Schenkel der Einpresskontakte gering ist. Eine geringe Ausdrückkraft oder auch Haltekraft ist auch bei Vibrationsbeanspruchungen, wie sie bei automotiven Anwendungen im Motorraum auftreten, nachteilig, da die Kontakte sich lockern und dadurch der Übergangswiderstand sich erhöht. Eine derartige Beschädigung kann zum Totalausfall der elektrischen Verbindung führen.In order not to damage the printed circuit board and its plated through-hole and in particular its inner conductor tracks during pressing in, it makes sense that the press-in contact is designed to be elastic, and if possible presses with little force on the hole wall. To achieve this, a low normal force of the voltage applied to the hole wall legs of the press-fit contacts should be sought. However, the necessary ejection force of the press-in contacts from the PCB holes must be relatively high for reasons of stability, especially for free-standing contacts. However, this quality-important requirement is not achievable with PCB end hole diameters below 1.00 mm and with material thicknesses of the press-fit contacts below 0.60 mm, especially if the normal force of the legs of the press-fit contacts is low. A low squeezing force or holding force is also at vibration stresses, such as occur in automotive applications in the engine compartment, disadvantageous because the contacts loosen and thereby the contact resistance increases. Such damage can lead to total failure of the electrical connection.

Aufgabenstellungtask
Der Erfindung liegt daher die Aufgabe zu Grunde, den elastischen Bereich des Einpresskontaktes derartig zu verändern, dass die Normalkraft der Kontaktschenkel des Einpresskontaktes relativ gering ist und der bauchige oder schräge Bereich bis zum Erreichen des größten Hüllkreisdurchmessers des Kontaktes erhalten bleibt, wodurch geringe Eindrückkräfte entstehen, die beim Ausdrücken des Einpresskontaktes entstehenden Ausdrückkräfte oder Haltekräfte aber relativ hoch sind. Des Weiteren darf die Durchkontaktierung der Leiterplatte nicht beschädigt werden, und der Übergangswiderstand muss möglichst gering sein.The invention is therefore based on the object to change the elastic region of the press-in contact such that the normal force of the contact legs of the press-in contact is relatively low and the bulbous or oblique region is maintained until reaching the largest Hüllkreisdurchmessers the contact, creating low Eindrückkräfte, but the expressing forces or holding forces arising when expressing the press-fit contact are relatively high. Furthermore, the through-connection of the printed circuit board must not be damaged, and the contact resistance must be as low as possible.
Gelöst wird die Aufgabe durch die im Anspruch 1 angegebene Erfindung. Die Unteransprüche stellen vorteilhafte Weiterbildungen der Erfindung dar.The problem is solved by the invention defined in
Wesentlich ist, dass in die nach außen gewölbten Kontaktschenkel des Einpresskontaktes durch druckbeaufschlagtes Verformen Vertiefungen eingebracht werden, deren Anfangsbereiche oberhalb des größten Hüllkreisdurchmessers des Einpresskontaktes liegen und Hinterschneidungen bilden, die sich in den jeweiligen Außenradien der Kontaktschenkel befinden. Beim Eindrücken fließt Material der Durchkontaktierung um die Kante der Hinterschneidung und wirkt hemmend auf die Ausdrückkraft, die dadurch erhöht wird. Durch die Lage der Hinterschneidungen oberhalb des größten Hüllkreisdurchmessers ist bedingt durch die Außenwölbung der Kontaktschenkel der Hüllkreisdurchmesser im Bereich der Hinterschneidungen kleiner und stellt beim Eindrücken keine Beeinträchtigung des gewünschten Gleiteffektes dar, da die Hinterschneidung im Schatten des größten Hüllkreisdurchmessers liegt.It is essential that in the outwardly curved contact legs of the press-in contact depressions are introduced by pressurized deformation whose initial ranges are above the largest Hüllkreisdurchmessers the press-fit and undercuts that are located in the respective outer radii of the contact legs. When pressed, material of the via flows around the edge of the undercut and inhibits the squeezing force, which is thereby increased. Due to the position of the undercuts above the largest Hüllkreisdurchmessers is caused by the outer curvature of the contact legs of the envelope circle diameter in the undercuts smaller and represents when impressing no impairment of the desired sliding effect, since the undercut lies in the shadow of the largest Hüllkreisdurchmessers.
In einem weiteren Ausführungsbeispiel werden anstatt der oder zusätzlich zu den Vertiefungen Erhöhungen eingebracht, hinter denen sich ebenfalls Hinterschneidungen bilden, die Hohlräume für das die Kante umfließende Material der Durchkontaktierung bilden. Wesentlich für dieses Ausführungsbeispiel ist, dass der Hüllkreisdurchmesser der Erhöhungen kleiner ist, als der größte Hüllkreisdurchmesser des Einpresskontaktes.In a further embodiment, elevations are introduced instead of or in addition to the recesses, behind which also undercuts form, the cavities for the material flowing around the edge of the Forming via. Essential for this embodiment is that the enveloping circle diameter of the elevations is smaller than the largest enveloping circle diameter of the press-fit.
