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).

Hochfrequenzspule, geeignet für automatische Bestückung von Leiterplatten und für automatischen AbgleichHigh-frequency coil, suitable for automatic assembly of printed circuit boards and for automatic alignment

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, deren Nachteil die große elektrische Streuung war. 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 coils of a simple type with only one winding etc. is still on the rise (communication devices, computer interfaces, Car electronics etc.) · So far one has helped to use fixed inductors, the disadvantage of which is the large electrical Scatter was. Therefore, if the allowable scatter was very small, the complicated filter structures for normal ones were used for this purpose HF resonant circuits used, although they were out of place per se.

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, but that in turn relatively complicated to manufacture »but a specific manufacturing process is optimally adapted.

Diese Konstruktion läßt sich erfindungsgemäß noch wesentlich vereinfachen, wenn der Herstellungsprozeß dieser Konstruktion angepaßt wird.According to the invention, this construction can still be simplified considerably, if the manufacturing process is adapted to this construction.

Dem Stand der Technik entspricht folgender Herstellungsprozeß:The following manufacturing process corresponds to the state of the art:

1. Spritzen des Spulenkörpers mit zwei lateralen Anschlußstiften,1. Injection of the bobbin with two lateral connector pins,

2. Bewickeln der Spule,2. winding the bobbin,

3. Verschweißen der Spulenenden mit den lateralen Anschlußstiften,3. Welding the coil ends to the lateral connection pins,

4. Fördern der bewickelten und verschweißten Spule zum Verschweißen der gegenüberliegenden Enden der lateralen Anschlußstifte mit gegurteten L-förmigen Drähten, die dann die eigentliche Verbindung zur Platine herstellen.4. Conveying the wound and welded coil for welding the opposite ends of the lateral connector pins with taped L-shaped wires, which then make the actual connection to the board.

Die erfindungsgemäße Spule wird folgendermaßen hergestellt:The coil according to the invention is manufactured as follows:

1. Spritzen des Spulenkörpers,1. Injection of the bobbin,

2. Eindrücken der L-förmigen, gegurteten Anschlußdrähte,2. Press in the L-shaped, taped connecting wires,

3. Bewickeln und Verschweißen in 4 bis 8-fach-Automaten am Gurt3. Wrapping and welding in 4 to 8-way machines on the belt

(Bei beiden Herstellverfahren wurde das übliche Einschrauben des Kerns nicht erwähnt).(In both manufacturing processes, the usual screwing in of the Kerns not mentioned).

Es ist ersichtlich, daß die erfindungsgemäße 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 is much more efficient to manufacture because (not mentioned) Sorting processes are also omitted.

Die erfindungsgemäße Spule wird nachstehend beschrieben:The coil according to the invention is described below:

(1) ist der Spulenkörperkopf, der ein Innengewinde zur Aufnahme eines Nippelkerns (9), der vorzugsweise einen Kreuzschlitz für den automatischen Abgleich aufweist, (2) ist der Spulenkörperfuß, in dem die L-förmigen Anschlußdrähte (5) eingebracht sind, die ihrerseits wieder radial in einem (isolierenden) Gurt (8) befestigt sind. Diese Drähte können rund, jedoch auch quadratisch sein, um eine Verdrehungssicherheit zu erreichen, (3) ist der eigentliche Wickelkörper, auf den die Spule (4) gewickelt ist, deren Enden an der Stelle (6) mit den Anschlußdrähten (5) vorzugsweise verschweißt sind.(1) is the bobbin head, which has an internal thread to accommodate a Nipple core (9), which is preferably a cross recess for the automatic Adjusting has, (2) is the bobbin foot, in which the L-shaped Connecting wires (5) are introduced, which in turn are again radially in one (insulating) belt (8) are attached. These wires can be round, but they can also be square in order to prevent twisting, (3) is the actual winding body on which the coil (4) is wound, the ends of which are preferably welded to the connecting wires (5) at the point (6) are.

Es ist je nach Anforderung an die erfindungsgemäße Hochfrequenz-Spule möglich, diese mit einem Rohrkern als magnetischen Schluß und/oder mit einem Abschirmbecher zu versehen.It depends on the requirements placed on the high-frequency coil according to the invention possible, this with a pipe core as a magnetic circuit and / or with to be provided with a shielding cup.
