Description

Die Erfindung bezieht sich auf eine Hochfrequenzspule gemäß dem Oberbegriff des Patentanspruchs 1 und auf ein Verfahren zum Herstellen von dieser.The invention relates to a high-frequency coil according to the preamble of claim 1 and to a method for producing the same.

Der Bedarf an Spulen einfacher Art mit nur einer Wicklung etc. ist nach wie vor im Steigen begriffen (Nachrichtengeräte, Computerschnittstellen, Autoelektronik etc.).. Bisher hat man sich damit geholfen, Festinduktivitäten zu verwenden, die jedoch insofern nachteilig sind, als sie eine große elektrische Streuung aufweisen. Es wurden daher, wenn die zulässige Streuung sehr gering war, für diesen Zweck die komplizierten Filteraufbauten für normale HF-Schwingkreise eingesetzt, obwohl sie an sich fehl am Platze waren.The need for simple type coils with only one winding, etc. is still increasing (communication devices, computer interfaces, car electronics, etc.). So far, it has helped to use fixed inductors, which are disadvantageous in that they are one have large electrical scatter. Therefore, if the permissible scatter was very small, the complicated filter structures for normal HF resonant circuits were used for this purpose, even though they were out of place.

Es gibt nun eine Konstruktion für derartige Spulen, die aber wiederum in der Herstellung relativ kompliziert, jedoch einem bestimmten Fertigungsprozess optimal angepasst ist.There is now a construction for such coils, which in turn is relatively complicated to manufacture, but is optimally adapted to a specific manufacturing process.

Diese Konstruktion kann gemäß der Erfindung noch wesentlich vereinfacht werden, wenn der Herstellungsprozess dieser Konstruktion angepasst wird.This construction can still be essential according to the invention be simplified if the manufacturing process of this construction is adapted to g .

)em Stande der Technik entspricht folgender Herstellungsprozess:

  • 1. Spritzen des Spulenkörpers mit zwei lateralen Anschlußstiften,
  • 2. Bewickeln der Spule,
  • 3. Verschweißen der Spulenenden mit den lateralen Anschlußstiften,
  • 4. Fördern der bewickelten und verschweißten Spule zum Verschweißen der gegenüberliegenden Enden der lateralen Anschlußstifte mit gegurteten L-förmigen Anschlußdrähten, die dann die eigentliche Verbindung zur Platine herstellen.
The following manufacturing process corresponds to the state of the art:
  • 1. injection of the coil body with two lateral connecting pins,
  • 2. winding the coil,
  • 3. welding the coil ends to the lateral connection pins,
  • 4. Convey the wound and welded coil to weld the opposite ends of the lateral connection pins with taped L-shaped connecting wires, which then establish the actual connection to the board.

Die erfindungsgemäße Spule wird folgendermaßen hergestellt:

  • 1. Spritzen des Spulenkörpers,
  • 2. Eindrücken der L-förmigen , gegurteten Anschlußdrähte,
  • 3. Bewickeln und Verschweißen in 4 bis 8-fach-Automaten am Gurt.
The coil according to the invention is manufactured as follows:
  • 1. spraying the bobbin,
  • 2. Pushing in the L-shaped, taped connecting wires,
  • 3. Winding and welding in 4 to 8-fold machines on the belt.

Im Vorstehenden wurde bei beiden Herstellungsverfahren das übliche Einschrauben des Kerns nicht erwähnt.In the above, the usual screwing-in of the core was not mentioned in both production processes.

Es ist ersichtlich, daß die erfindungsgemäßen Hochfrequenzspule wesentlich rationeller herzustellen ist, weil auch (nicht genannte) Sortiervorgänge zusätzlich entfallen.It can be seen that the high-frequency coil according to the invention can be produced much more efficiently because sorting processes (not mentioned) are also ent fall.

Die Erfindung wird nachstehend an einem Ausführungsbei-4 spiel anhand der Zeichnung noch näher erläutert. In der Zeichnung zeigt:

  • Fig. 1 eine erfindungsgemäße Hochfrequenzspule in Ansicht von oben,
  • Fig. 2 die Spule gemäß Fig. 1 in Seitenansicht mit Blickrichtung senkrecht zum Gurt,
  • Fig. 3 die Spule nach Fig. 1 in Seitenansicht mit Blickrichtung parallel zum Gurt, und
  • Fig. 4 mehrere erfindungsgemäße Spulen am Gurt nebeneinander in Seitenansicht mit Blickrichtung senkrecht zum Gurt.
The invention is explained in more detail below using an exemplary embodiment with reference to the drawing. The drawing shows:
  • 1 is a radio frequency coil according to the invention in a view from above,
  • 2 the spool of FIG. 1 in a side view looking perpendicular to the belt,
  • Fig. 3 shows the spool of FIG. 1 in a side view looking in the direction parallel to the belt, and
  • Fig. 4 several coils according to the invention on the belt side by side in a side view looking perpendicular to the belt.
