Description

Verfahren zur Herstellung Diner unhygroskopischen Lagerung, insbesondere eines Ab- oder Einschlusses, von elektrischen Leitern mittels Wickel aus Fäden oder Bändern aus gerecktem Polystyrol Es ist bekannt, luftraumisolierte und insbesondere konzentrische Adern elektrischer Hochfrequenzkabel dadurch mit sog. Abstandhaltern zu versehen, daß auf den Leibern bzw. Innenleitern in Abständen Wickel aus dünnen gereckten Polystyrolbändern hergestellt werden. Das gereckte Polystyrol ist im Handel unter dem durch Warenzeichen geschützten Namen »Styroflex« erhältlich.Method of making diner unshygroscopic storage, in particular an enclosure or inclusion, of electrical conductors by means of a winding of threads or Strips of expanded polystyrene It is known to be airspace-insulated and in particular concentric cores of electrical high-frequency cables with so-called spacers to provide that on the bodies or inner conductors at intervals of thin wraps stretched polystyrene tapes are produced. The expanded polystyrene is on the market available under the trademarked name »Styroflex«.

Mittels solcher um elektrische Leiter, bei konzentrischer Leiteranordnung gegebenenfalls auch zwischen sie gelegter Wickel aus Bändern oder in diesem Fall auch aus Fäden aus gerecktem Polystyrol wird gemäß der Erfindung eine unhygroskop-ische Lagerung, insbesondere ein Abschluß oder Einschluß, von elektrischen Leitern dadurch hergestellt, daß die Fäden oder Bänder nach dem Wickeln, also in gewickeltem Zustand; durch mäßige Erwärmung mindestens teilweise entreckt werden.By means of such around electrical conductors, with concentric conductor arrangement possibly also wraps of ribbons placed between them, or in this case threads made of stretched polystyrene also become unhygroscopic according to the invention Storage, particularly a closure or enclosure, of electrical conductors thereby manufactured that the threads or tapes after winding, that is, in the wound state; be at least partially removed by moderate heating.

Die durch die mäßige Erwärmung erfolgende Entreckung ist mit einer Schrumpfung der Länge der Fäden oder Bänder verbunden, wodurch die Wickel ganz dicht zusammengezogen werden, so daß eine unhygroskopische, auch gegen kapillare Feuchtigkeitsaufnahme sichere Lagerung der elektrischen Leiter entsteht. Die Erwärmung kann auch so weit getrieben werden, daß die Fäden oder Bänder in den Wickeln zusammenbacken oder sogar ganz verschmelzen. Die jeweils geeignete Temperatur und Länge der Wärmebehandlung läßt sich durch Versuche feststellenr.The dehulling caused by the moderate heating is with a Shrinkage of the length of the threads or tapes connected, whereby the Wraps are pulled together very tightly, so that an unhygroscopic, even against capillary moisture absorption, safe storage of electrical conductors is created. The heating can also be carried out so far that the threads or ribbons in the Bake them together or even completely melt them together. The appropriate temperature in each case and the length of the heat treatment can be determined by experiments.

Die Erfindung führt den Vorteil herbei, daß das Polystyrol in einer festen Form auf oder um die Leiter, insbesendere auch sehr dünne Leiter, gebracht werden bann (also z. B. nicht gegossen zu werden braucht, was übrigens in einigen Fällen gar nicht möglich ist) und doch eine im Vergleich zu Wgickeln aus anderen Stoffen, z. B. Lackleinenband, viel dichtere Wicklung entsteht. Eine Lötung der Leiter nach Ausführung der Erfindung ist ohne weiteres möglich, wie praktische 'Versuche schon gezeigt haben.The invention brings about the advantage that the polystyrene in one fixed form on or around the ladder, especially very thin ladder are banned (e.g. does not need to be poured, which incidentally in some Cases is not possible at all) and yet one in comparison to wraps from others Substances, e.g. B. vinyl linen tape, much denser winding is created. A soldering of the Head according to the embodiment of the invention is readily possible, such as practical 'experiments have already shown.

Als einige Beispiele für Anwendungsfälle der Erfindung seien genannt: Kabelmuffen und Kabelendverschlüsse, insbesondere auch sog. Wickelendverschlüsse; Durclhfühirungen aller Art, z. B. auch durch Gehäuse von elektrischen Apparaten, auch sog. Kondensatordurchführungen: Abschlüsse von beweglichen oder festverlegten Hochfrequenzleitungen aller Art, insbesondere auch von Hochfrequenzspulen.Some examples of applications of the invention may be mentioned: Cable sleeves and cable terminations, in particular also so-called coil terminations; Performances of all kinds, e.g. B. also through the housing of electrical equipment, also so-called condenser bushings: terminations of movable or fixed ones High-frequency lines of all kinds, in particular also from high-frequency coils.

Besonders nützlich ist die Erfindung bei solchen Leitern, die auf ihrer übrigen Länge bereits mit einer Isolation aus Polystyrol versehen sind, da sich dann eine besonders gute Verbindung der Lagerstelle mit der übrigen Isolation der Liter ergibt. Die Erfindung kann auch dazu benutzt werden. um Löt-, Klemmen- oder Steckverbindungen elektrischer Leiter, insbesondere auch bei konzentrischer Leiteranordtnung, mechanisch und damit auch elektrisch zu sichern, indem die Schrumpfunsg der Polystyrolfäden oder Bänder in den um die Verbindungsstellen gelegten Wickeln ausgenutzt wird.The invention is particularly useful in such ladders that on their remaining length are already provided with polystyrene insulation, there Then there is a particularly good connection between the bearing point and the rest of the insulation the liter results. The invention can also be used for this purpose. around soldering, terminal or plug connections of electrical conductors, especially with concentric Conductor arrangement to be secured mechanically and thus also electrically by the shrinkage the polystyrene threads or ribbons in the wraps around the joints is exploited.

Einige Ausführungsb2ispiele der Erfindung für Kabelarmaturen sind in der Zeichnung in Fig. I bis 4 dargestellt und ohne weitere Erläuterung verständlich. Zur Herstellung der Wickel können auch allmählich schmäler werdende Polystyrolbänder verwendet werden.Some embodiments of the invention for cable fittings are Shown in the drawing in Fig. I to 4 and understandable without further explanation. Gradually narrowing polystyrene tapes can also be used to produce the winding be used.

Es ist ein Verfahren zur Herstellung einer Luftraumisolierung für elektrische Leiter bekannt, hei welchemn auf den Leiter ein Abstandhalter für eine Isolierumhüllung schraubenförmig aufgewickelt wird. Dieser Abstandhalter besteht aus verschieden breiten Bandschichten aus gerecktem Polystyrol, die abwechselnd übereinandler gewickelt sind. Die vorragenden Ränder der breiteren Bänder werden derart erwäirmt, cla daß diese Ränder ein wenig zusammenlaufen, um rippenartige Verdiclkungen zu bilden. Die Erwärmung der vorragenden Bandränder bei demn beckannten Verfahren hat einen wesentlich anderen Zweck als die Erwärmung der gesamten Fäden oder Bänder beim Erfindungsgegenstand. Durch die bei demn bekannten Verfahren infolge der Erwärmung der vorragenden Bandränder hervorgerufenen rippenartigen Verdickungen soll eine Verschiebung der zwischen den breiten Bandschichten angeordneten schmalen Bandschichten verhindert werden. Beinm Erfindungsgegenstand sollen dagegen durch das Erwärmen der gesamten Fäden oder Bänder die aus ihnen Bergestellten Wickel derart erstreckt werden, daß diese Wickel dicht zusammengezogen werden und infolgedessen eine unthgroskopische, auch gegen kapillare sichere Lagerung der elektrischen Liter erzielt wird.It is a method of producing air space insulation for electrical conductor known, he whichn on the conductor a spacer for a Insulating jacket is wound helically. This spacer is made made of different widths of tape layers made of expanded polystyrene, which alternate are wrapped on top of each other. The protruding edges of the wider bands will be in such a way heated that these edges converge a little to form rib-like To form thickenings. The warming of the protruding band edges on the beckennen The purpose of the process is significantly different from that of heating the entire thread or ribbons in the subject matter of the invention. Due to the known method in demn rib-like thickenings caused by the heating of the protruding band edges is intended to shift the narrow ones arranged between the broad layers of tape Tape layers are prevented. In contrast, with the subject matter of the invention the heating of the entire threads or tapes, the wraps salvaged from them in this way are extended so that these wraps are pulled tightly together and as a result an ungroscopic storage of the electric liters, which is also safe against capillary action is achieved.
