Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines kunststoffumspritzten Kontaktelementes für die Nachrichtentechnik, vorzugsweise eines Kabelsteckers.The invention relates to a method for producing a plastic-encapsulated contact element for communications technology, preferably a cable connector. Bei der modernen Herstellung von Steckern wird im allgemeinen das vormontierte Steckelement, das schon mit den Kabelanschlüssen elektrisch verbunden ist, samt dem Kabel mit Kunststoff umspritzt. Im allgemeinen geschieht die Verbindung durch Löten, Nieten, Schweissen und dergleichen.In the modern manufacture of plugs, the preassembled plug element, which is already electrically connected to the cable connections, is generally overmoulded with plastic together with the cable. In general, the connection is made by soldering, riveting, welding and the like. Der Erfindung liegt die Aufgabe zugrunde, für diese Art der Herstellung, insbesondere von solchen Kontaktelementen den Herstellungsvorgang zu vereinfachen.The object of the invention is to simplify the production process for this type of production, in particular for such contact elements. Diese Aufgabe wird gemäss der Erfindung bei einem Element der eingangs genannten Art dadurch gelöst, dass für eine erforderliche Lötstelle zwischen zu kontanktierenden Anschlussteilen diese Teile zueinander mechanisch in einer Spritzform festgelegt werden und unter Beigabe eines Lotdepots, dessen Material auf die Schmelztemperatur des Kunststoffes abge-5 stellt ist und vice versa, in einem Arbeitsgang mit Kunststoff umspritzt und verlötet werden.According to the invention, this object is achieved with an element of the type mentioned at the outset in that, for a required soldering point between connecting parts to be connected, these parts are mechanically fixed to one another in an injection mold and with the addition of a solder depot, the material of which is reduced to the melting temperature of the plastic and vice versa, can be overmoulded with plastic and soldered in one operation. Weitere vorteilhafte Ausgestaltungen des Erfindungsgegenstandes finden sich in den abhängigen Patentansprüchen.Further advantageous configurations of the subject matter of the invention can be found in the dependent patent claims. Auf diese Weise kann vorteilhaft einfach während des io Kunststoffumspritzens von derartigen Metallteilen durch die freiwerdende Wärme das eingelegte Lotdepot zum Beispiel ein Lötring, eine Lötpille, ein Lötformteil zum Schmelzen gebracht werden, da relativ hohe Einspritztemperaturen ein relativ niedrig schmelzendes Weichlot genügend erhitzen, um die interne 15 Lötverbindung gleichzeitig mit dem Umspritzen herzustellen. Neben der Lötung der Bauteile erhöht so der umgebende Kunststoff die Festigkeit der Weichlotverbindung. Auf diese Weise wird ferner vermieden, dass bei vor dem Kunststoffum-spritzen gelöteten Stellen durch neuerliche Erhitzung eine Art 20 kalte Lötstelle entsteht. Andernfalls müsste die Lötverbindung durch Hartlöten oder durch Punktschweissen hergestellt werden, was natürlich höheren Fertigungsaufwand erfordert.In this way, the inserted solder depot, for example a soldering ring, a soldering pill, a soldering molded part, can be melted easily during the plastic encapsulation of such metal parts by the heat released, since relatively high injection temperatures heat a relatively low-melting soft solder sufficiently to induce the internal 15 solder connection to produce simultaneously with the encapsulation. In addition to soldering the components, the surrounding plastic increases the strength of the soft solder connection. In this way, it is also avoided that a kind of cold soldering point occurs in the case of points soldered before the plastic encapsulation by renewed heating. Otherwise, the soldered connection would have to be made by hard soldering or by spot welding, which of course requires more manufacturing effort. Treten beim Einspritzen des Kunststoffes grössere Turbulenzen auf, ist eine Verlagerung des Lötgutes möglich, die jedoch 25 durch Hilfsmassnahmen wie zum Beispiel Metallschalen, Kappen, Hülsen oder durch geeignete Konstruktionsauslegung gebunden werden kann. Bei den zu lötenden Teilen werden geeignete Oberflächen-Paarungen verwendet, um zusätzliche Flussmittel zu vermeiden, die eventuell den umspritzten Kunst-30 Stoff auflösen.If major turbulence occurs when injecting the plastic, it is possible for the item to be soldered to shift, but this can be contained by means of auxiliary measures such as metal shells, caps, sleeves or by suitable structural design. Appropriate surface matings are used on the parts to be brazed to avoid additional fluxes which may dissolve the overmolded Art-30. Das Ausführungsbeispiel zeigt einen umspritzten Koaxial-Winkelstecker mit Kabel. In zentrischer Lagerung werden Aus-senleiterhülse 1 und Innenleiter 2 in die Spritzform eingelegt, wobei auf den Innenleiter 9 eine zusätzliche Hülse 4 mit einer 35 Lotpille 5 aufgesteckt wird. Das Koaxialkabel 6 wird nach definierten Massen abisoliert, wobei auf den aus Drahtgeflecht oder Metallfolie bestehenden Aussenleiter 7 ein Weichlotring 8 aufgeschoben wird. Die Spritzform muss so ausgelegt sein, dass das abisolierte Kabel auf Innenleiter und der Aussenleiter mit 40 Lotring zum Anliegen kommt. Nach Schliessen der Spritzform wird Thermoplast eingespritzt, füllt die Leerräume 3 und bringt das Weichlot zum Schmelzen.The embodiment shows an overmolded coaxial right-angle connector with cable. Outer conductor sleeve 1 and inner conductor 2 are placed in the injection mold in a centric position, with an additional sleeve 4 having a solder pill 5 being slipped onto inner conductor 9 . The coaxial cable 6 is stripped according to defined dimensions, with a soft solder ring 8 being pushed onto the outer conductor 7 consisting of wire mesh or metal foil. The injection mold must be designed in such a way that the stripped cable comes into contact with the inner conductor and the outer conductor with a 40 solder ring. After the injection mold is closed, thermoplastic is injected, fills the empty spaces 3 and causes the soft solder to melt. Dies gilt auch für anderweitige kunststoffumspritzte Lötstellen allgemein.This also applies to other plastic-coated solder joints in general. vv 1 Blatt Zeichnungen1 sheet of drawings
