Abstract

Plastic extrusion-coated contact elements, for example cable plugs, are required in many cases in electrical engineering, especially in information technology. In order to permit economical production of such parts, the soldering point which is to be extrusion coated is provided with additional solder (5, 8) whose melting point is matched to the plastic (3) which is to be injection moulded, so that the solder (5, 8) melts at the same time when the plastic (3) is injection moulded and produces the electrical contact between the parts (2, 9,1,7) which are to be connected. <IMAGE>

Description

Kunststoffumspritztes Kontaktelement für die Nachrichten-Plastic encapsulated contact element for communication

technik. vorzugsweise Kabelstecker Die Erfindung bezieht sich auf ein kunststoffumspritztes Kontaktelement für die Nachrichtentechnik, vorzugsweise Kabelstecker.technology. preferably cable connector The invention relates to a plastic-coated contact element for communications technology, preferably 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, Schweinen und dergleichen.In the modern manufacture of connectors, this is generally used pre-assembled plug-in element that is already electrically connected to the cable connections is, including the cable, coated with plastic. In general, the connection occurs by soldering, riveting, porking and the like.

Der Erfindung liegt die Aufgabe -zugrunde, für diese Art der Herstellung, insbesondere von solchen Eontaktelementen den Herstellungsvorgang zu vereinfachen.The invention is based on the object, for this type of manufacture, in particular to simplify the manufacturing process of 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 kontaktierenden Anschlußteilen diese-Teile zueinander mechanisch in der Spritzform festgelegt sind und unter Beigabe eines Lotdepots, dessen Material auf die Schmelztemperatur des Kunststoffes abgestellt ist und vice versa, in einem Arbeitsgang mit Kunststoff umspritzt und verlötet sind.This object is achieved according to the invention in an element of the opening paragraph mentioned type solved in that for a required solder joint between to be contacted Connection parts of these parts are mechanically fixed to one another in the injection mold and with the addition of a solder deposit, the material of which is adjusted to the melting temperature of the Plastic is turned off and vice versa, in one operation with plastic are overmolded and soldered.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgegenstandes finden sich in den Unteransprüchen.Find further advantageous embodiments of the subject matter of the invention in the subclaims.

Auf diese Weise kann vorteilhaft einfach während des Kunststoffumspritzens von derartigen Metallteilen durch die freiwerdende Wärme das eingelegte Lotdepot zum Bei-Spiel ein Lötring, eine Lötpille, ein Lötformteil zum Schmelzen gebracht werden, da relativ hohe Einspritttètperaturen ein relativ niedrig schmelzendes Weichlot genügend erhitzen, um die interne 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 Kunststoffumspritzen gelöteten Stellen durch neuerliche Erhitzung eine Art kalte Lötstelle entsteht. Andernfalls müßte die Lötverbindung durch Hartlöten oder durch Punktschweißen hergestellt werden, was natürlich höheren Fertigungsaufwand erfordert.In this way, it can advantageously be carried out simply during the plastic encapsulation of such metal parts through the released heat the inserted Solder depot for example a solder ring, a solder pill, a solder preform for melting be brought because relatively high injection temperatures a relatively low melting point Heat the soft solder sufficiently to make the internal solder joint at the same time as the overmoulding to manufacture. In addition to the soldering of the components, the surrounding plastic increases the Strength of the soft solder connection. In this way it is also avoided that at A kind of cold solder joint occurs. Otherwise the soldered connection would have to be brazed or can be produced by spot welding, which of course involves higher manufacturing costs requires.

Treten beim Einspritzen des Kunststoffes größere Turbulenzen auf, ist eine Verlagerung des Lötgutes möglich, die jedoch 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 Kunststoff auflösen. If greater turbulence occurs when the plastic is injected, it is possible to move the item to be soldered, but this can be prevented by auxiliary measures such as For example metal shells, caps, sleeves or through suitable construction design can be bound. Suitable surface pairings are used for the parts to be soldered used to avoid additional flux that might be overmolded Dissolve plastic.

Das Ausführungsbeispiel zeigt einen umspritzten Koaxial-Winkelstecker mit Kabel. In zentrischer Lagerung werden Außenleiterhülse 1 und Innenleiter 2 in die. Spritzform eingelegt, wobei auf den Innenleiter 9 eine zusätzliche Hülse 4 mit einer 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 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 angled connector with cable. In a central position, the outer conductor sleeve 1 and the inner conductor 2 are in the. Injection mold inserted, with an additional sleeve 4 on the inner conductor 9 is attached with a solder pill 5. The coaxial cable 6 is defined according to Dimensions stripped, with the outer conductor made of wire mesh or metal foil 7 a soft solder ring 8 is pushed on. The injection mold must be designed so that the stripped cable on the inner conductor and the outer conductor with solder ring to the contact comes. After the injection mold is closed, thermoplastic is injected, filling the empty spaces 3 and melts the soft solder.

Dies gilt auch für anderweitige kunststoffumspritzte Lötstellen allgemein.This also applies in general to other plastic-encapsulated soldering points.
