Abstract

1. Method for the manufacture of one-sidedly banded high-frequency coils provided for the automatic equipping of circuit boards, in which method the coil bodies (1, 2, 3) are injection-moulded and each have the winding (4) wound on them and a connection is made between the winding ends and the banded L-shaped connecting wires (5) serving for the connection to a circuit board, wherein the banded L-shaped connecting wires (5) are pressed into the coil bodies (1, 2, 3) before these are being wound on and the coil bodies (1, 2, 3) are being wound on automatically at the band (8) and the winding ends are connected directly with the L-shaped connecting wires (5).

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von einseitig gegurteten Hochfrequenzspulen.The invention relates to a method for producing high-frequency coils taped on one side.

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 been helped to use fixed inductors, but they are disadvantageous in that they have a large electrical scatter. Therefore, if the permissible scatter was very small, the complicated filter structures for normal RF 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 mit der im Anspruch 1 definierten Erfindung noch wesentlich vereinfacht werden, da der Herstellungsprozeß dieser Konstruktion angepaßt wird.This construction can be significantly simplified with the invention defined in claim 1, since the manufacturing process of this construction is adapted.

Dem 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 prior 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.

Es ist auch bereits bekannt, bei der Herstellung eines Spulenkörpers Anschlußdrähte, die zu einem Klemmenstreifen zusammengefaßt sind, vor dem Bewickeln des Spulenkörpers in diesen einzudrücken (DE-A-1 922 276). Die zu einem Klemmenstreifen zusammengefaßten Anschlußdrähte sind nicht in nebeneinander liegender Anordnung gegurtet. Die einzelnen Klemmenstreifen befinden sich vielmehr an einem Klemmenstreifenband hintereinander, wobei der jeweils vorderste Klemmenstreifen in Richtung parallel zur Längsmittelachse des Spulenkörpers in diesen eingedrückt und dann von dem dahinter befindlichen Klemmenstreifenband abgetrennt wird. Um sich von dem Spulenkörper senkrecht zu dessen Längsmittelachse erstreckende Anschlußdrähte für die Wicklungsenden zu erhalten, ist noch ein sich an das Eindrücken anschließender aufwendiger Biegeprozess erforderlich. Die auf diese Weise erhaltenen Spulenkörper mit Anschlußdrähten haben nach dem Eindrück- und Biegeprozess des Klemmenstreifens untereinander keinerlei Verbindung.It is also already known, in the manufacture of a coil former, to press connecting wires, which are combined to form a terminal strip, before winding the coil former (DE-A-1 922 276). The connecting wires combined into a terminal strip are not taped in an adjacent arrangement. Rather, the individual terminal strips are located one behind the other on a terminal strip strip, the frontmost terminal strip being pressed into the coil body in the direction parallel to the longitudinal central axis of the coil former and then being separated from the terminal strip strip located behind it. In order to obtain connecting wires for the winding ends extending from the coil former perpendicular to its longitudinal center axis, a complex bending process following the indentation is still required. The bobbins with connecting wires obtained in this way have no connection to one another after the pressing-in and bending process of the terminal strip.

Das erfindungsgemäße Herstellungsverfahren läuft folgendermaßen ab:

  • 1. Spritzen des Spulenkörpers,
  • 2. Eindrücken der L-förmigen, gegurteten Anschlußdrähte,
  • 3. Bewickeln und Verschweißen in 4- bis 8fach-Automaten am Gurt.
The manufacturing process according to the invention proceeds 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 allen Herstellungsverfahren das übliche Einschrauben des Kerns nicht erwähnt.In the foregoing, the usual screwing in of the core was not mentioned in all manufacturing processes.

Es ist ersichtlich, daß die erfindungsgemäße Herstellung von Hochfrequenzspulen wesentlich rationeller ist, weil auch (nicht genannte) Sortiervorgänge zusätzlich entfallen.It can be seen that the production of high-frequency coils according to the invention is considerably more efficient because sorting processes (not mentioned) are also eliminated.

Die Erfindung wird nachstehend an einem Ausführungsbeispiel anhand der Zeichnung noch näher erläutert. In der Zeichnung zeigt:

  • Fig. 1 eine nach dem erfindungsgemäßen Verfahren hergestellte 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 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 shows a high-frequency coil produced by the method 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 on the belt side by side in a side view looking perpendicular to the belt.
