Description

Elektrisch beheizter Rohrheizkörper, dessen Heizleiterende innerhalb des Rohres mit einem litzenförmigen Ansehlußleiter verbunden ist Bei elektrischen Rohrheizkörpern ist es bc- kannt, den innerhalb eines. Metallrohres in einer elektrisch isolierenden Schicht einge- betteten Helzlelter mit dem meist litzeilföi-lnt- gen Stromzuführungsdraht in. der Weise zti verbinden, daß zwischen Heizleiter und An- sChluß ein verhältnismäßig starres und nach 'Möglichkeit nicht heizendes Zwischengliled in Gestalt eine Verbindun`;-sdralites von st=irkc- rein Querschnitt als dem des Heizleiters cin- geschoben ist, das so«-ohl mit dem 1eiz- leiter als auch dein Stronizufübrungsdralit verlötet wird. Bei einer derartigen Anord- nung läßt sich das. isolierende Füllmittel innerhalb des Rohrendes gut einbringen. Auch ist ein Stauchen des Heizleiter- endes hierbei nicht zu befürchten. Außer- dem läßt sich mit Hilfe der gelöteten Verbindungsstelle des in Windungen ge- führten Zwischengliedes mit dem einge- steckten Ende der Stromzuführungslitze eine wirksame Zugentlastung für die Heiz- leiter schaffen. Bei den bisher bekannten Anordlltlilgell waren bei Verwendung sehr dünner Heiz- leiter je zwei Lötstellen an. jedem Rohrende notwend7, und zwar eine zum Verbinden von Zwischenglied und Heizleiter und eine zweite zum Verbinden von Zwischenglied und Anschlußlitze. Um die eine dieser Lötstellen, und zwar dieerstgenannte , entbehrlich zu machen, erstreckt sich erfindungsgemäß das Ende des Heizleiters über die ganze Länge des drahtförmigen Zwischengliedes, reicht also bis zum Isoliernippel, und die metal- lische Verbindung von Zwischenglied, An- schlußlitze und Heizleiter erfolgt gemeinsam. Hierdurch wird wie bei der bereits bekann- ten Ausführung die notwendige Steifigkeit des Heizleiters am Ende des Rohres er- zielt, jedoch ist die Herstellung #u-enüber dieser sehr vereinfacht. Die Abbildung zeigt eine der möglichen Ausfuh'run:gsf0'rlnen. Innerhalb des Meiz- rohres a, isoliert durch verschiedene Fiill- mittel b, verläuft der schraubenförmig ge;t-u;:- d@en@e - Heizleiter c mit den Stramzufiili2-un s- teilen. Das Rolir ende ist mit dem Endnippel c1 i-crschlossen, durch den der litzenförnii@;e Ari- schlul'.@draht t#, hindurchgeführt ist. Uln dem I,feizl,eiter zwecks günstigen Aufstampfens des Füllm;ittcls im Rohrende eine gröl: ere StAfi- keit zti -elen., ist ein drahtförmiges Zuischen- g@ied f, J, 1t vorgesehen, das im @ Bereich f, in welchem es den Anschlußdraht e schraub ün- förinig umgibit, sowohl mit dieseln wie auch mit ckm Ende des Heizleiters c, das auf de:- ganzen L äne f, s, lt nehr-n dein clralitföi-nii- =sen Zwischenglied verläuft. verliitet is.. Es ist also: nur eine einzige Lötstelle erfoi-der- lich, die ztisammcn mit dem Endnippel als Ztt-ei:tlastting für den Heizleiter dienen k@aiil.

With such an arrangement The insulating filler can be used Insert well inside the pipe end. Compression of the heating conductor end of this not to be feared. Except- this can be done with the help of the soldered Connection point of the coiled inserted pontic with the inserted stuck the end of the power supply cord effective strain relief for the heating create a ladder. In the previously known arrangement were when using very thin heating conductors two soldering points each. each end of the pipe necessary, one to connect of intermediate link and heating conductor and one second to connect pontic and Pigtail. Around one of these solder joints namely the first-mentioned, dispensable too make, extends according to the invention End of the heating conductor over the entire length of the wire-shaped intermediate link is sufficient up to the insulating nipple, and the metal connection of pontic, connecting trailing wire and heating conductor are made together. As with the already known the necessary rigidity of the heating conductor at the end of the pipe aims, however, the production is # u-enover this very simplified.
