Description

Bei' elektrischen' Geräten, z. B. bei Pupinspulen und Übertragern, werden häufig die zum Anschluß herausgeführten Leiterenden zusätzlich mit Schläuchen aus warmbildsamem Stoff versehen, die zu diesem Zweck auf die Leiterenden aufgeschoben sind. Hierbei hat sich der Übelstand gezeigt, daß diese Isolierschläuche während der Herstellung der Spulen leicht vom Leiter abrutschen und verlorengehen. Man hat sich bisher vielfach in der Weise zu helfen gesucht, daß man die Isolierschläuche mit Bindfaden oder Isolierband auf dem Leiter festlegte. .For 'electrical' devices, e.g. B. with Pupin coils and transformers, the conductor ends led out for connection are often additionally covered with hoses made of warm-forming fabric, which is pushed onto the ends of the ladder for this purpose are. Here, the disadvantage has been shown that these insulating hoses during easily slip off the conductor and get lost during the manufacture of the coils. One has So far often sought to help in such a way that the insulating hoses Fixed with string or electrical tape on the conductor. .

Nach der- Erfindung sind die Isolierschläuche mittels Druck und Wärme auf dem Leiter befestigt. Diese Anbringung ist zuverlässiger als das bisher angewandte Festbinden. Außerdem ist sie einfacher und rascher auszuführen und beansprucht weniger Platz. Die Zeichnung zeigt beispielsweise eine Pupinspule nach der Erfindung. Es bezeichnen i den bewickelten ferromagnetischen Kern und 2 die zum Anschluß der Spule herausgeführten Leiterenden, auf die die aus Polyvinylchlorid bestehenden Isolierschläuche 3 aufgeschoben sind. Diese Schläuche sind bei q. mittels Druck und-Wärme auf dem Leiter befestigt.According to the invention, the insulating tubes are by means of pressure and heat attached to the ladder. This attachment is more reliable than the one previously used Tie up. In addition, it is easier and quicker to carry out, and it is less demanding Place. The drawing shows, for example, a Pupin's coil according to the invention. It i denote the wound ferromagnetic core and 2 the one for connecting the coil Lead out conductor ends on which the insulating tubes made of polyvinyl chloride 3 are postponed. These hoses are at q. by means of pressure and heat on the Head attached.
