Description

Die Erfindung betrifft eine fluiddichte Kontaktdurchführung durch einen Kunststoffkörper, mit mindestens einem Flachkontakt, der auf einem umspritzten Teilstück eine oder mehrere Querschnittsänderungen aufweist, wobei ein dauerelastisches Dichtmittel zwischen die Grenzflächen des mindestens einen Flachkontakts und des Kunststoffkörpers eingebracht ist.The invention relates to a fluid-tight contact bushing through a plastic body, with at least one flat contact having one or more cross-sectional changes on an overmolded portion, wherein a permanently elastic sealant between the boundary surfaces of the at least one flat contact and the plastic body is introduced.

Eine derartige Kontaktdurchführung ist aus der US-Patent Application Publication US 2009/0258521 A1 bekannt. Das Dokument zeigt einen Flachkontakt und eine mit dem Flachkontakt verbundene Anschlussleitung, die jeweils abschnittsweise mit einem ringförmigen Dichtungselement versehen und mit einem isolierenden synthetischen Polymer umspritzt sind.Such a contact bushing is known from the US Patent Application Publication US 2009/0258521 A1 known. The document shows a flat contact and a connecting line connected to the flat contact, which are each provided in sections with an annular sealing element and encapsulated with an insulating synthetic polymer.

Eine weitere fluiddichte Kontaktdurchführung ist aus der DE 10 2009 058 525 A1 bekannt. Bei dieser Kontaktdurchführung weist der Flachkontakt mindestens einen Abschnitt mit einer umlaufend sich in axialer Richtung verjüngenden Querschnittskontur auf. Nach dem Umspritzen wird der Flachkontakt in Richtung seiner Verjüngung(en) gegen die Umspritzung verschoben, wodurch die Kavitäten entlang der Mantelflächen der sich verjüngenden Kontur verschlossen werden und so die Kontaktdurchführung entlang axialer Abschnitte des Flachkontakts abgedichtet wird.Another fluid-tight contact bushing is from the DE 10 2009 058 525 A1 known. In this contact bushing, the flat contact has at least one section with a circumferentially tapering cross-sectional contour in the axial direction. After encapsulation, the flat contact is displaced in the direction of its taper (s) against the encapsulation, whereby the cavities are closed along the lateral surfaces of the tapered contour and so the contact bushing is sealed along axial sections of the flat contact.

Die Kavitäten, die hier durch die Verschiebung des Flachkontakts abgedichtet werden, entstehen durch Schrumpfungsprozesse beim Abkühlen des Kunststoffmaterials. Besonders thermoplastische Materialien verändern beim Abkühlen ihre innere Struktur, wodurch sich das Materialvolumen vermindert. Durch diese Nachschwindung entsteht zu dem Kontakt ein kleiner Spalt, der auf die beschriebene Weise abgedichtet wird. Allerdings ist unter schwierigen Umgebungsbedingungen, wie hohen Drücken und Temperaturen, die dabei erreichbare Dichtigkeit oft nicht ausreichend.The cavities, which are sealed here by the displacement of the flat contact, are caused by shrinkage processes during cooling of the plastic material. Especially thermoplastic materials change their internal structure during cooling, which reduces the volume of material. By this Nachschwindung formed to the contact a small gap, which is sealed in the manner described. However, it is difficult Ambient conditions, such as high pressures and temperatures, the achievable tightness often insufficient.

Anspruchsvolle Umgebungsbedingungen sind beispielsweise bei Steckverbindern gegeben, die in Getriebegehäusen von Kraftfahrzeugen eingebaut sind. Solche Steckverbinder sind wechselnden Temperaturen und dabei auch hohen Temperaturdifferenzen ausgesetzt und müssen Schwingungen, sowie hohen Öldrücken standhalten. Für derartige Anwendungen werden nahezu ausschließlich Steckverbinder mit Rundstiften eingesetzt. Diese werden zumeist unter hohem Krafteinsatz in Durchgangsöffnungen eines Kunststoffkörpers eingepresst, die ein Untermass gegenüber dem Querschnittsmaß der Rundstifte aufweisen.Challenging environmental conditions are given for example in connectors that are installed in gearboxes of motor vehicles. Such connectors are exposed to changing temperatures and thereby high temperature differences and must withstand vibrations and high oil pressures. For such applications almost exclusively plug connectors are used with round pins. These are usually pressed with high force into through holes of a plastic body, which have an undersize with respect to the cross-sectional dimension of the round pins.

Ein derartiges Vorgehen hat sich bei Flachkontakten als problematisch erwiesen, da die Anpresskräfte innerhalb der Durchgangsöffnung nicht symmetrisch auf die Oberfläche des Steckerkontakts wirken. Als besonders schwierig hat sich dabei die Abdichtung im Bereich der Längskanten eines Flachkontakts herausgestellt, da sich hier die Richtung der Oberflächennormale unstetig ändert. Dies führt dazu, dass eine ausreichende Öldichtigkeit von Getriebegehäusesteckverbindern mit Flachkontakten in den typischen Temperatur- und Druckbereichen bisher nicht erreichbar war.Such a procedure has proved to be problematic in flat contacts, since the contact forces within the passage opening do not act symmetrically on the surface of the plug contact. The sealing in the region of the longitudinal edges of a flat contact has proved to be particularly difficult, since the direction of the surface normal changes discontinuously here. As a result, sufficient oil-tightness of gear housing connectors with flat contacts in the typical temperature and pressure ranges has not been achievable so far.

In der nicht vorveröffentlichten deutschen Patentanmeldung DE 10 2011 121 133 wird eine Kontaktdurchführung vorgeschlagen, deren Kunststoffkörper aus einem nichtschwindenden Duroplastmaterial besteht und bei der die Längskanten des mindestens einen umspritzten Flachkontakts verrundet sind. Eine fluiddichte Kontaktdurchführung wird so durch die Kombination eines besonders gewählten Umspritzungsmaterials mit einer besonderen Formgebung des Flachkontakts erreicht. Beide Merkmale zusammen schaffen eine Kontaktdurchführung, die mindestens fluiddicht ist und die, für einen definierten Druckbereich, sogar gasdicht ausgebildet sein kann. Allerdings ist die Gasdichtigkeit einer solchen Kontaktdurchführung, abhängig von der Art des Gases, auf nicht allzu hohe Drücke beschränkt.In the not previously published German patent application DE 10 2011 121 133 a contact bushing is proposed, the plastic body consists of a non-shrinking thermoset material and in which the longitudinal edges of the at least one overmolded flat contact are rounded. A fluid-tight contact feedthrough is thus achieved by the combination of a specially selected encapsulation material with a special shape of the flat contact. Both features together create a contact bushing which is at least fluid-tight and which, for a defined pressure range, may even be gas-tight. However, that is the gas tightness of such a contact bushing, depending on the nature of the gas, limited to not too high pressures.

Es stellte sich die Aufgabe, eine gattungsgemäße Kontaktdurchführung mit Flachkontakten zu schaffen, die bei hohen Drücken und Temperaturen sowie auch über einen großen Temperaturbereich fluiddicht sowie möglichst vibrations- und chemikalienbeständig ist und sich darüber hinaus durch eine besonders hohe Gasdichtigkeit auszeichnet.It has set itself the task of creating a generic contact bushing with flat contacts, which is fluid-tight at high pressures and temperatures and over a wide temperature range and vibration and chemicals as possible and also characterized by a particularly high gas tightness.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Kunststoffkörper aus einem nichtschwindenden Duroplastmaterial besteht, und dass das Dichtmittel nach dem Aushärten des Duroplastmaterials durch ein Imprägnationsverfahren eingebracht ist.This object is achieved in that the plastic body consists of a non-shrinking thermoset material, and that the sealant is introduced after curing of the thermoset material by an impregnation process.

Unter einem dauerelastischen Dichtmittel wird hier ein Material verstanden, welches über längere Zeiträume und größere Temperaturbereiche elastische Eigenschaften beibehält. Bei der Herstellung der Kontaktdurchführung wird ein niedrigviskoser Elastomergrundstoff eingesetzt, der sich anschließend zu dem dauerelastischen Dichtmittel verfestigt.Under a permanently elastic sealant is understood here as a material which retains elastic properties over long periods and larger temperature ranges. In the production of the contact bushing, a low-viscosity elastomer base material is used, which then solidifies into the permanently elastic sealant.

Wesentlich ist hierbei zunächst die Verwendung eines Duroplastmaterials zur Umspritzung des mindestens einen Flachkontakts. Im Gegensatz zu den üblicherweise zum Spritzgießen verwendeten Thermoplasten finden sich unter den Duroplasten Materialien, welche ihr Volumen beim Aushärten nicht verringern, sondern konstant halten oder sogar vergrößern. Als für die hier zu lösende Aufgabe haben sich nichtschwindende Duroplastmaterialien, die auch als "Nullschwinder" bezeichnet werden, die ihr Volumen weder vermindern noch vergrößern, als geeignet erwiesen. Derartige Materialien finden sich beispielsweise in den Stoffgruppen der Epoxydharze, Phenolharze oder der so genannten Bulk Moulding Compounds (BMC). Die Verwendung eines nichtschwindenden Duroplastmaterials ermöglicht es, einen Flachkontakt zu umspritzen, ohne dass es beim Aushärten des Umspritzungsmaterials zu einer Ausbildung von Kavitäten kommt.Essential here is first the use of a thermoset material for encapsulation of the at least one flat contact. In contrast to the thermoplastics commonly used for injection molding, thermosets contain materials which do not reduce their volume during curing but keep it constant or even increase it. As for the problem to be solved here, non-shrinking thermoset materials, which are also referred to as "zero-decayers", which neither reduce nor increase their volume, have proven suitable. Such materials are found, for example, in the substance groups of epoxy resins, phenolic resins or the so-called bulk molding compounds (BMC). The use of a non-shrinking thermoset material allows for flat contact overmold without the formation of cavities during curing of Umspritzungsmaterials.

Allerdings kann auch bei einem nichtschwindenden Duroplastmaterial die Ausbildung mikroskopisch kleiner Mikrorisse, Kapillaren etc. im Kunststoffmaterial oder im Übergangsbereich zwischen Kunststoffkörper und Flachkontakt nicht ausgeschlossen werden, was die Gasdichtigkeit der Kontaktdurchführung auf nicht allzu hohe Drücke beschränkt.However, the formation of microscopic micro-cracks, capillaries etc. in the plastic material or in the transition region between plastic body and flat contact can not be excluded even with a non-shrinking thermoset material, which limits the gas tightness of the contact bushing to not too high pressures.

Dieses Problem wird nun dadurch gelöst, dass beim Umpritzungsprozess unvermeidlich entstehende winzige Undichtigkeiten mit einem nachträglich eingebrachten elastomeren Material abgedichtet werden. Hierzu haben sich besonders sogenannte Imprägnationsverfahren als geeignet erwiesen, welche einen noch nicht verfestigten Elastomergrundstoff durch Druckunterschiede an die abzudichtenden Stellen befördert.This problem is now solved by the inevitably resulting tiny leaks are sealed with a subsequently introduced elastomeric material during Umpritzungsprozess. For this purpose, particularly so-called impregnation have proven to be suitable, which conveys a not yet solidified elastomer base by pressure differences at the sealed sites.

Dies kann beispielsweise dadurch geschehen, dass eine Kontaktdurchführung, bestehend aus einem oder mehreren mit einem nichtschwindenden Duroplastmaterial umspritzten Flachkontakten, in ein Bad mit dem noch nicht verfestigten Elastomergrundstoff gesetzt wird, welche dann unter einen hohen Druck gesetzt wird, wodurch der Elastomergrundstoff selbst in enge Kapillaren der Kontaktdurchführung eindringt.This can be done, for example, that a contact bushing, consisting of one or more overmolded with a non-shrinking thermoset flat contacts, is placed in a bath with not yet solidified elastomer base, which is then placed under a high pressure, whereby the elastomer base even in narrow capillaries the contact penetration penetrates.

Besonders vorteilhaft einsetzbar ist eine sogenannte Vakuumimprägnation, bei der in einem Vakuum zunächst sämtliche Feuchtigkeits- und Gaseinschlüsse aus den Kapillaren der Kontaktdurchführung entfernt werden, so dass der Elastomergrundstoff danach als Imprägnierung problemlos in die Kapillaren eindringen kann.Particularly advantageous is a so-called vacuum impregnation, in which all moisture and gas inclusions are removed from the capillaries of the contact bushing in a vacuum, so that the elastomer base material can then penetrate easily as impregnation in the capillaries.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den abhängigen Ansprüchen hervor.Further advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Um beim Umspritzungsvorgang eine gleichmäßige Verbindung zwischen dem Duroplastmaterial und dem Flachkontakt zu gewährleisten, kann optional vorgesehen werden, die Längskanten des mindestens einen Flachkontakts zu verrunden.In order to ensure a uniform connection between the thermoset material and the flat contact during Umspritzungsvorgang, may optionally be provided to round the longitudinal edges of the at least one flat contact.

Dies kann vorteilhaft dadurch erreicht werden, dass die Längskanten des mindestens einen Flachkontakts auf der Gratseite durch einen Stanzprozess vorgeprägt und dadurch umlaufend verrundet sind. Der Flachkontakt weist somit keinen genau rechteckförmigen Querschnitt auf, sondern einen rechteckförmigen Querschnitt mit abgerundeten Übergängen zwischen den Querschnittsseiten. Dieses Profil ist schematisch in der Figur 5 dargestellt. Der mindestens eine Flachkontakt weist zudem auf einem umspritzten Teilstück an seinen Randabschnitten eine oder mehrere rechteckförmige oder abgerundete Aussparungen aus, wie sie beispielhaft in den Figuren 3 und 4 dargestellt sind. Hierdurch variiert die Querschnittsbreite des Flachkontakts in dessen axialer Richtung.This can advantageously be achieved in that the longitudinal edges of the at least one flat contact on the ridge side by a punching process pre-stamped and rounding rounded thereby. The flat contact thus has no exactly rectangular cross-section, but a rectangular cross-section with rounded transitions between the cross-sectional sides. This profile is schematic in the FIG. 5 shown. The at least one flat contact also has on a molded portion at its edge portions of one or more rectangular or rounded recesses, as exemplified in the FIGS. 3 and 4 are shown. As a result, the cross-sectional width of the flat contact varies in its axial direction.

Die Ausnehmungen bewirken, dass der mindestens eine Flachkontakt nach der Umspritzung formschlüssig mit dem Umspritzungsmaterial verbunden ist. Die Ausnehmungen bilden zudem in axialer Richtung des Flachkontakts eine Labyrinthstruktur aus, welche für das angrenzende Medium einen mehrstufigen Druckabfall bewirkt, wodurch sich die Abdichteigenschaften der Kontaktdurchführung weiter verbessern. Hierbei wirkt unterstützend, dass das Umspritzungsmaterial erfindungsgemäß bei der Verarbeitung sein Materialvolumen nicht verändert und daher die Ausnehmungen dicht ausfüllt.The recesses cause the at least one flat contact after the encapsulation is positively connected to the Umspritzungsmaterial. The recesses also form in the axial direction of the flat contact a labyrinth structure, which causes a multi-stage pressure drop for the adjacent medium, thereby further improving the sealing properties of the contact bushing. In this case, it is supportive that the overmolding material according to the invention does not change its material volume during processing and therefore fills the recesses tightly.

Besonders vorteilhaft ist es, wenn der mindestens eine Flachkontakt und das Umspritzungsmaterial möglichst ähnliche und im Idealfall gleiche Temperaturausdehnungskoeffizienten aufweisen. Hierdurch können in einem weiten Temperaturbereich sowohl mechanische Spannungen als auch Kavitätsbildungen, welche die Abdichtungseigenschaften verschlechtern würden, vermieden werden.It is particularly advantageous if the at least one flat contact and the overmolding material have as similar as possible and ideally the same temperature expansion coefficients. As a result, both mechanical stresses and cavity formations, which would impair the sealing properties, can be avoided over a wide temperature range.

Besonders vorteilhaft ist auch, dass aufgrund der guten Abdichteigenschaften und der hohen Temperaturbeständigkeit des nichtschwindenden Duroplastmaterials die nicht umspritzten Endabschnitte des mindestens einen Flachkontakts durch einen Galvanikprozess behandelt werden können, ohne dass die umspritzten Bereichen davon betroffen sind. Hierdurch können die umspritzten und die nicht umspritzten Bereiche des mindestens einen Flachkontakts mit unterschiedlichen galvanischen Beschichtungen versehen werden, die für den jeweiligen Bereich besonders günstige Eigenschaften aufweisen.It is also particularly advantageous that due to the good sealing properties and the high temperature resistance of the non-shrinking thermoset material, the non-encapsulated end portions of the at least one flat contact can be treated by a galvanic process, without the encapsulated areas are affected. This allows the overmolded and the non-overmolded areas of the at least one flat contact are provided with different galvanic coatings, which have particularly favorable properties for the respective area.

So kann beispielsweise vorteilhaft vorgesehen sein, dass ausschließlich die nicht umspritzten Bereiche des mindestens einen Flachkontakts eine Zinn- oder Silberbeschichtung aufweisen.For example, it may be advantageously provided that only the non-overmolded regions of the at least one flat contact have a tin or silver coating.

Hierzu können im Fertigungsablauf zuerst die nicht oberflächenbehandelten und gegebenenfalls mit einem Anlaufschutz versehenden Flachkontakte umspritzt werden, und anschließend die aus dem Kunststoffkörper herausstehenden Enden der Flachkontakte oberflächenbehandelt und gegebenenfalls passiviert werden. Da hierdurch nur Teilabschnitte der Flachkontakte behandelt werden, wird zudem vorteilhaft eine Einsparung von Silber und Passivierungsmittel erreicht.For this purpose, the non-surface-treated and optionally provided with a tarnish protection flat contacts can be encapsulated in the production process first, and then the surfaces protruding from the plastic body ends of the flat contacts surface-treated and optionally passivated. Since this only partial sections of the flat contacts are treated, also advantageously a saving of silver and passivation is achieved.

Weitere Details zur vorteilhaften Ausgestaltungen einer erfindungsgemäßen Kontaktdurchführung gehen aus der nachfolgend beschriebenen Zeichnung hervor. Die Figur 1 zeigt eine Schnittansicht eines Steckverbindergehäuses 6, welches eine fluiddichte Durchführung von Flachkontakten 1 zwischen zwei Kammern 9, 10 aufweist. Das Steckverbindergehäuse 6 ist als ein Spritzgießteil gefertigt, wobei zur Herstellung des Steckverbindergehäuses 6 Teilabschnitte 4 der Flachkontakte 1 mit einem nichtschwindenden Duroplastmaterial umspritzt wurden.Further details of the advantageous embodiments of a contact bushing according to the invention will be apparent from the drawing described below. The FIG. 1 shows a sectional view of a connector housing 6, which has a fluid-tight passage of flat contacts 1 between two chambers 9, 10. The connector housing 6 is made as an injection molded part, wherein for the production of the connector housing 6 sections 4 of the flat contacts 1 were encapsulated with a non-shrinking Duroplastmaterial.

Die in der Figur 1 dargestellte zweipolige Ausführung einer Kontaktdurchführung ist selbstverständlich rein beispielhaft. Eine erfindungsgemäße Kontaktdurchführung kann eine frei festlegbare Anzahl von umspritzten Flachkontakten 1 aufweisen, insbesondere sind auch Kontaktdurchführungen mit jeweils einem einzigen Flachkontakt 1 oder auch mit einer höheren Anzahl von Flachkontakten 1 ausführbar. Die Figur 2 zeigt als weiteres Beispiel eine Kontaktdurchführung mit sieben Flachkontakten 1, die in drei zueinander parallelen Reihen angeordnet sind.The in the FIG. 1 shown two-pole version of a contact bushing is of course purely exemplary. A contact feedthrough according to the invention can have a freely definable number of molded flat contacts 1, in particular also contact feedthroughs, each with a single flat contact 1 or else executable with a higher number of flat contacts 1. The FIG. 2 shows a further example, a contact bushing with seven flat contacts 1, which are arranged in three mutually parallel rows.

Nach dem Umspritzen der Flachkontakte 1 mit dem Duroplastmaterial, wird (in den Figuren nicht dargestellt) die Kontaktdurchführung in ein Bad mit einem noch nicht verfestigten Elastomergrundstoff gebracht, welcher dann unter einen hohen Druck gesetzt wird, wodurch der Elastomergrundstoff in feinste verbliebene Zwischenräume (Kapillaren) zwischen dem Kunststoffkörper 2 und den Flachkontakten 1 eingepresst wird.After encapsulation of the flat contacts 1 with the thermoset material, (not shown in the figures), the contact bushing is placed in a bath with a not yet solidified elastomer base, which is then placed under a high pressure, whereby the elastomer base in the finest remaining spaces (capillaries) is pressed between the plastic body 2 and the flat contacts 1.

Alternativ oder zusätzlich wird hierbei ein Vakuumimprägnationsverfahren angewendet, bei dem in einem Vakuum zunächst sämtliche Feuchtigkeits- und Gaseinschlüsse aus den Kapillaren der Kontaktdurchführung entfernt werden, so dass der Elastomergrundstoff als Imprägnierung problemlos die Kapillaren eindringen kann.Alternatively or additionally, in this case a vacuum impregnation method is used, in which all moisture and gas inclusions are removed from the capillaries of the contact bushing in a vacuum, so that the elastomer base material can easily penetrate the capillaries as an impregnation.

In der Figuren 3 und 4 ist jeweils ein einzelner Flachkontakt 1, 1' dargestellt, welcher an einem Teilstück 4 von einer Umspritzung 3 umgeben ist. Die als schraffierte Fläche dargestellte Umspritzung 3 verdeutlicht hierbei schematisch jeweils ein den Flachkontakt 1, 1' direkt umgebendes Teilvolumen eines Kunststoffkörper 2, wie er in den Figuren 1 bzw. 2 gezeigt ist.In the FIGS. 3 and 4 in each case a single flat contact 1, 1 'is shown, which is surrounded on a section 4 by an encapsulation 3. In this case, the encapsulation 3 shown as a hatched area schematically illustrates in each case a partial volume of a plastic body 2 which directly surrounds the flat contact 1, 1 ', as is shown in FIGS FIGS. 1 or 2 is shown.

Innerhalb des von der Umspritzung 3 umgebenen Teilstückes 4 weist der Flachkontakt 1, 1' mehrere Querschnittsänderungen auf, die in Form abgerundeter Ausnehmungen 5a (Figur 3) beziehungsweise rechteckförmiger Ausnehmungen 5b (Figur 4) in die Längsseiten des Flachkontakts 1 bzw. 1' eingebracht sind. Die Umspritzung 3 bildet mit den Ausnehmungen 5a bzw. 5b eine formschlüssige Verbindung aus, welche aufgrund der "Nullschwinder-Eigenschaften des dazu vorgesehen Duroplastmaterials in einem weiten Temperatur- und Druckbereich fluiddicht ist.Within the section 4 surrounded by the encapsulation 3, the flat contact 1, 1 'has a plurality of cross-sectional changes, which are in the form of rounded recesses 5a (FIG. FIG. 3 ) or rectangular recesses 5b (FIG. FIG. 4 ) are introduced into the longitudinal sides of the flat contact 1 or 1 '. The encapsulation 3 forms with the recesses 5a and 5b from a positive connection, which due to the "zero Schwinder properties the thermosetting material provided is fluid-tight in a wide temperature and pressure range.

Noch nach dem Umspritzungsvorgang können nicht umspritzte Endabschnitte 7a, 7b des Flachkontaktes 1, 1' galvanisch behandelt werden; beispielsweise zu Verbesserung der elektrischen Kontakteigenschaften mit einer Silbersbeschichtung versehen werden.Even after the encapsulation process, non-encapsulated end sections 7a, 7b of the flat contact 1, 1 'can be treated galvanically; For example, to improve the electrical contact properties are provided with a silver coating.

Die Figur 5 zeigt einen Abschnitt aus dem in der Figur 4 dargestellten Flachkontakt 1' in einer Querschnittsansicht. Ersichtlich ist eine der Ausnehmungen 5b, durch die die Querschnittsbreite b des Flachkontakts 1' in dessen axialer Richtung a variiert. Erkennbar sind außerdem abgerundete Längskanten 8 des Flachkontakts 1', welche auf der Stanzseite durch das Stanzwerkzeug und auf der Gratseite durch eine Vorprägung an den Flachkontakt 1' angeformt sind. Die abgerundete Längskanten 8 verbessern wesentlich die Verbindung des Flachkontakts 1' zum Umspritzungsmaterial.The FIG. 5 shows a section from the in the FIG. 4 illustrated flat contact 1 'in a cross-sectional view. One of the recesses 5b, by which the cross-sectional width b of the flat contact 1 'varies in the axial direction a, can be seen. Visible are also rounded longitudinal edges 8 of the flat contact 1 ', which are formed on the punching side by the punching tool and on the ridge side by a pre-stamping to the flat contact 1'. The rounded longitudinal edges 8 substantially improve the connection of the flat contact 1 'to Umspritzungsmaterial.
