Description

Verfahren zum Verzinnen von Hocbfrequenzlitzen Die Erfindung betrifft ein Verfahren zum Verzinnen von Hochfrequenzlirzen. Hochfrequen:zlitzen müssen am Anschlußen:de so verzinnt werden, daß die Verzinnung sämtliche Einzeldrähte einwandfrei erfaßt.Method for tinning high frequency strands The invention relates to a process for tinning high frequency fibers. High frequencies: have to zlitzen am Connections: de are tinned in such a way that the tinning of all individual wires is flawless recorded.

Nach den bisher üblichem Methoden wurde zur Verzinnung das nach der Lackentfernung bereits wieder oder noch verdrallte Drahtende, unter Umständen unter Anwendung eines Lötmittels, in das Zinnbad getaucht. Eine de;7artige Verzinnung liefert jedoch nur dann einigermaßen befriedigende Ergebnisse, wenn säurehaltiges Lötfett angewendet wird. Bei Geräten der elektrischen Nachrichtenübertragungs- und Meßtechnik ist jedoch die Anwendung neutraler Lötmittel aus Korrosionsgründen unbedingt erforderlich. Nach den bisher üblichen Verfahren kann daher bei der Anwendung neutraler Lötmittel eine einwandfreie, ins Innere der Hochfrequenelitze durchgreifende und alle einzelnem, Drähte umfassende Verzinnung nicht erreicht werden.According to the methods customary up to now, tinning was carried out according to the Paint removal already again or twisted wire end, possibly under Applying solder, dipped in the tin bath. A de; 7-type tinning however only gives reasonably satisfactory results when acidic Soldering grease is applied. In devices of the electrical communication and Measurement technology, however, requires the use of neutral solder for reasons of corrosion necessary. According to the methods customary up to now, the application can therefore be more neutral Solder a flawless, penetrating into the interior of the high-frequency wire and all individual tin-plating comprising wires cannot be achieved.

Diese Mängel lassen sich gemäß der Erfindung dadurch vermeiden, daß das, insbesondere blank gemachte, zu verzinnende Ende der Litze ganz oder teilweise äufgesippleißt und im Zinnbad nach dem Verzinnen wieder verdrallt wird. Durch diese Methode erreicht man, daß die einzelnen blank gemachten Drähte des aufgespleiBten Endes der Litze im Zinnbad einer einwandfreien Verzinnung zugänglich sind. Da das anschließende Verdrillen der einzelnen Drähte im Zinnbad selbst erfolgt, ist auch das wieder verdrillte Ende der Litze, in das Innere durchgreifend und alle einzelnen Drähte umfassend, verzinnt. Das Blankmachen der zu verzinnenden Drahtenden erfolgt je nach Isolierung bzw. Beschaffenheit der Litzen sowie der einzelnen Drähte vor oder näch dem AufspleiBen und kann bei geeigneter Isolierung bzw. Beschaffenheit der Drähte unter Umständen auch ganz entfallen, insbesondere dann, wenn zur Isolierung eine die Lötung nicht störende Lackierung verwendet wurde. Eine derartige Methode zur einwandfreien Verzinnung von Hohfrequenzlitzen am AnschluBende ist beispielsweise zur Erlangung eines hohen Gütefaktors bei der Herstellung von Spulen mit Hochfrequenzlitze von. großer Bedeutung.These deficiencies can be avoided according to the invention in that the end of the strand to be tinned, in particular bare, in whole or in part is spliced up and twisted again in the tin bath after tinning. Through this method one achieves that the individual exposed wires The spliced end of the strand is accessible for perfect tinning in the tin bath are. Since the subsequent twisting of the individual wires takes place in the tin bath itself, is also the re-twisted end of the strand, reaching through to the inside and all comprising individual wires, tinned. Making the wire ends to be tinned bright takes place depending on the insulation or the nature of the strands and the individual wires before or after fanning and can be done with suitable insulation or properties the wires may also be completely omitted, especially if for insulation a coating that does not interfere with the soldering was used. One such method for the perfect tinning of high frequency strands at the connection end is for example to achieve a high quality factor in the manufacture of coils with high-frequency braided wire from. great importance.
