Description
Stand der TechnikState of the art
In der
Bei dieser Ausführung ist nachteilig, dass zur Abdichtung und damit zur Vermeidung eines Lokalelements zwischen dem Steckelement aus Kupfer und dem Draht aus Aluminium ein zunächst nicht fester und nicht gasförmiger Stoff verwendet wird, der erst durch Bestrahlung mit ultraviolettem Licht aushärtet. Dies ist nicht nur aufwändig, sondern birgt auch die Gefahr, dass das nicht ausgehärtete Harz den lokal begrenzten Bereich in Gestalt einer Wanne verlässt und dabei beispielsweise die Fertigungsumgebung verunreinigt. Es ist auch denkbar, dass das Steckerteil dabei beschichtet wird. Es könnte dabei der Nachteil auftreten, dass ein Kontaktbereich nur noch eingeschränkt kontaktieren kann, da das Harz eine Kontaktfläche isoliert. In this embodiment, it is disadvantageous that a first non-solid and non-gaseous substance is used to seal and thus to avoid a local element between the plug of copper and the wire made of aluminum, which cures only by irradiation with ultraviolet light. This is not only costly, but also involves the risk that the uncured resin leaves the localized area in the form of a pan, thereby contaminating, for example, the manufacturing environment. It is also conceivable that the plug part is coated thereby. The disadvantage could occur that a contact area can only contact to a limited extent since the resin isolates a contact area.
Im Rahmen der Erfindung ist vorgesehen, einerseits nicht feste und nicht gasförmige Stoffe in der Fertigung zu vermeiden und andererseits einen ausreichend sicheren Abstand zwischen den Materialien unterschiedlicher Elektronegativität herzustellen. In the context of the invention, it is provided on the one hand to avoid non-solid and non-gaseous substances in the production and on the other hand to produce a sufficiently safe distance between the materials of different electronegativity.
Offenbarung der ErfindungDisclosure of the invention
Gemäß den Merkmalen des unabhängigen Anspruchs 1 ist vorgesehen, dass das Verfahren die Anordnung des mechanischen Leitelements (beispielsweise in Gestalt eines isolierten Drahts oder einer isolierten Litze) derartig vorsieht, dass eben dieser erste elektrische Leiter durch ein mechanisches Leitelement derartig gestützt wird, dass der Endabschnitt des elektrischen Leiters freikragend gestützt ist. Dies hat beispielsweise den Vorteil, dass sich an dem freikragenden Teil keine Feuchtigkeit niederschlagen kann, die in Verbindung mit Materialien unterschiedlicher Elektronegativität zu einem Lokalelement führen würde. Zudem könnte man den freien Endabschnitt des Leiters, d. h. hier die Schnittstelle des Leiters, die durch Einkürzen des Leiters entstanden ist, unisoliert lassen. Dies erspart zusätzlichen Isolationsaufwand. According to the features of independent claim 1 it is provided that the method provides the arrangement of the mechanical guide element (for example in the form of an insulated wire or an insulated stranded wire) such that this first electrical conductor is supported by a mechanical guide element such that the end section of the electrical conductor is supported freikragend. This has the advantage, for example, that no moisture can precipitate on the free-standing part, which, in combination with materials of different electronegativity, would lead to a local element. In addition, one could the free end portion of the conductor, d. H. Here the interface of the conductor, which was created by shortening the conductor, leave uninsulated. This saves additional isolation effort.
Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen. So ist beispielsweise vorgesehen, dass der freie Endabschnitt des Leiters zwischen einer Verbindungsstelle und einem Ende des ersten elektrischen Leiters gebogen wird. Dies hat den Vorteil, dass dadurch ein Abstand zu benachbarten Abschnitten des Steckermaterials bzw. des Materials an der Verbindungsstelle, d. h. des haltenden Materials, besonders weit voneinander entfernt sein können. Further advantages of the invention will become apparent from the dependent claims. For example, it is provided that the free end portion of the conductor is bent between a connection point and an end of the first electrical conductor. This has the advantage that thereby a distance to adjacent portions of the connector material or the material at the connection point, d. H. of the holding material, especially far apart.
Es ist dabei vorgesehen, dass der freie Endabschnitt entweder in eine Achsrichtung oder gar in zwei Achsrichtungen gebogen ist. Zwecks Verringerung des Materialaufwands und des Aufwands von Stoffverbindungen ist vorgesehen, dass ein Halteabschnitt und das Leitelement einstückig aus dem zweiten elektrischen Leiter herausgearbeitet werden. Das Herausarbeiten von Halteabschnitt und Leitelement kann dabei durch kombinierte bzw. nacheinander folgende Arbeitsvorgänge wie Stanzen und Biegen eines Blechelements erfolgen. Wie bereits zuvor erwähnt, ist vorgesehen, dass der freie Endabschnitt ein blankes Ende aufweist, welches nach seiner Herstellung unisoliert bleibt. It is provided that the free end portion is bent either in an axial direction or even in two axial directions. In order to reduce the material cost and the expense of fabric compounds is provided that a holding portion and the guide element are machined in one piece from the second electrical conductor. The working out of holding section and guide element can be done by combined or successively following operations such as punching and bending a sheet metal element. As already mentioned above, it is provided that the free end section has a bare end, which remains uninsulated after its manufacture.
Zur Formgebung des zweiten Leiters, der bevorzugt und unmittelbar Teil der Steckverbindung ist, ist vorgesehen, dass der zweite Leiter aus einem Blech geschnitten wird und zur Herstellung des Leitelements der zweite Leiter eingeschnitten und an der so entstandenen Schnittstelle mindestens zwei Bereiche des Leiters in mindestens einer Achsrichtung gegeneinander verschoben werden. Dies hat den Vorteil eines besonders einfachen Fertigungsverfahrens. For shaping the second conductor, which is preferably and immediately part of the connector, it is provided that the second conductor is cut from a sheet metal and cut to produce the guide element of the second conductor and at the interface thus formed at least two regions of the conductor in at least one Axial direction are shifted against each other. This has the advantage of a particularly simple manufacturing process.
Gemäß einem weiteren Anspruch ist vorgesehen, dass der freie Endabschnitt in eine andere Richtung als das Leitelement gerichtet wird. According to another claim, it is provided that the free end portion is directed in a different direction than the guide element.
