Description

Die Erfindung betrifft ein Verfahren zur elektrischen Kontaktierung und Isolierung eines elektrischen Bauelements, insbesondere einer Ringkernspule mit laschenförmigen Anschlußelementen.The invention relates to a method for electrical contacting and insulation of an electrical component, in particular a toroidal core coil with tab-shaped connecting elements.

Bei bereits bekannten Verfahren dieser Art werden die bewickelten Ringkerne, insbesondere Ferritringkerne, in mit Anschlußstifte ausgebildete Becher eingesetzt, die Wickeldrahtenden an die Anschlußstifte angewickelt und mit diesen verlötet, wonach der Becher mit Kunstharz ausgegossen wird.In already known methods of this type, the wound toroidal cores, in particular ferrite toroidal cores, are inserted into cups formed with connecting pins, the winding wire ends are wound onto and soldered to the connecting pins, after which the cup is poured out with synthetic resin.

Üblich ist auch, daß der bewickelte Ringkern auf eine Trägerplatte mit Anschlußstiften aufgesetzt wird, anschließend die Wickeldrahtenden an die Anschlußstifte angewickelt, mit diesen verlötet und die Drahtenden gekürzt werden, wonach die so kontaktierte Ringkernspule mit einer Kunststoffolie umzogen wird.It is also common that the wound toroid is placed on a carrier plate with pins, then the winding wire ends are wound onto the pins, soldered to them and the wire ends are shortened, after which the toroid coil contacted in this way is removed with a plastic film.

Der vorliegenden Erfindung liegt gleichfalls die Aufgabe zugrunde, ein Verfahren zur Kontaktierung elektrischer Bauelemente, insbesondere Ringkernspulen, zu schaffen, das sich jedoch durch erhöhte Einfachheit und ein wenig aufwendiges Isolierverfahren auszeichnet, das gleichzeitig eine feste Verbindung der Anschlußelemente mit dem elektrischen Bauelement gewährleistet.The present invention is also based on the object to provide a method for contacting electrical components, in particular toroidal coils, which is, however, characterized by increased simplicity and a less expensive insulation method, which at the same time ensures a firm connection of the connection elements with the electrical component.

Bei einem Verfahren der eingangs genannten Art sieht die Erfindung zur Lösung der gestellten Aufgabe vor, daß bandförmige Träger aus elektrisch leitendem Material und mit einstückig angeformten Laschen zu den elektrischen Bauelementen herangeführt und die freien Enden der Laschen mit den elektrischen Kontakten der elektrischen Bauelemente verlötet Werden, daß anschließend die Bauelemente samt Laschen elektrostatisch mit Kunststoffpulver bedeckt und durch nachfolgende Wärmebehandlung die Laschen an die Bauelemente angesintert werden, wonach die Träger abgetrennt werden.In a method of the type mentioned, the invention provides to achieve the object that band-shaped carrier made of electrically conductive material and with integrally molded tabs to the electrical construction Elements brought up and the free ends of the tabs are soldered to the electrical contacts of the electrical components, that the components together with the tabs are then electrostatically covered with plastic powder and the tabs are sintered onto the components by subsequent heat treatment, after which the carriers are separated.

Zur Aufnahme der Anschlußdrähte der elektrischen Bauele- mente, z.B. der Wickeldrahtenden von Ringkernspulen, werden dabei die freien Enden der Laschen in einem ggf. mit weiteren Arbeitsgängen integrierten Arbeitsgang geschlitzt.For receiving the lead wires of the electrical Bauele- m duck, for example, the winding wire ends of the toroidal coil, while the free ends of the tabs are slotted in a possibly integrated with further operations operation.

Eine zusätzliche Montageerleichterung wird bewirkt, wenn die Laschen stufenförmig gekrümmt bzw. gekröpft werden, so daß diese Laschenteile als Auflager für die elektrischen Bauelemente verwendbar sind.An additional ease of assembly is achieved if the tabs are curved or cranked in steps, so that these tab parts can be used as supports for the electrical components.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Es.zeigt:

  • Fig. 1 bis 4 in perspektivischer, schematischer und teilweise gebrochener Darstellung wesentliche Fertigungsabschnitte,
  • Fig. 5 eine abgewandelte Ausführungsform des bandförmigen Trägers nach Fig. 1 und 2.
The invention is explained below with reference to the drawing. It shows:
  • 1 to 4 in perspective, schematic and partially broken representation of essential manufacturing sections,
  • Fi g. 5 shows a modified embodiment of the band-shaped carrier according to FIGS. 1 and 2.

Einleitend wird zunächst ein zu einer in der Zeichnung nicht dargestellten Rolle aufgespultes Band aus elektrisch leitendem Material von der Rolle abgezogen und durch Stanzen in gewünschte, in der Fertigung zueinander parallel ausgerichtete Abschnitte 1 unterteilt, die mit einstückig angeformten Laschen 2 ausgebildet sind. Die vorzugsweise im gleichen Arbeitsgang in ihren freien Endbereichen mit Schlitzen 12 ausgestatteten Laschen werden in einem nachfolgenden Arbeitsschritt gekröpft, wie dies bei 3 dargestellt ist und auf diese als Auflager dienenden Kröpfungen selbsttätig Ringkernspulen 4 aufgelegt, deren Wicklungsenden in die Schlitze 12 eingeklemmt, mit den Laschen verlötet - siehe Bezugszeichen 5 - und gekürzt werden.Initially, a strip of electrically conductive material that is wound into a roll (not shown in the drawing) is first pulled off the roll and divided by punching into desired sections 1 that are parallel to one another in production and that are formed with integrally formed tabs 2. The tabs, which are preferably equipped with slots 12 in their free end areas in the same operation are cranked in a subsequent work step, as shown at 3, and toroidal coils 4 are automatically placed on these cranks serving as supports, the winding ends of which are clamped in the slots 12, soldered to the tabs - see reference number 5 - and shortened.

Anschließend werden die beispielsweise zu Chargen zusammengefaßten und mit Laschen kontaktierten Ringkernspulen elektrostatisch mit Kunststoffpulver 7 bedeckt und durch eine z.B. 5-minütige, nachfolgende Wärmebehandlung bei ca. 200°C die Laschen 2 mechanisch fest an die Ringkernspulen 4 angesintert. Die bandförmigen Träger 1, die während der elektrostatischen Beschichtung als Massekontakte verwendbar sind, werden schließlich nach erfolgter Besdichtung und Wärmebehandlung abgetrennt.Subsequently, the toroidal core coils, which are combined, for example, into batches and contacted with tabs, are electrostatically covered with plastic powder 7 and coated with e.g. 5 minutes, subsequent heat treatment at approx. 200 ° C., the tabs 2 are mechanically firmly sintered onto the toroidal coils 4. The band-shaped carriers 1, which can be used as ground contacts during the electrostatic coating, are finally separated off after the sealing and heat treatment have taken place.

Eine abgewandelte Ausführungsform eines Trägers zeigt Fig. 5. Die beiden bandförmigen Träger 1 nach Fig. 1 sind dabei zu einem U-Profilförmig gekrümmten und mit an den Schmalseiten 9, 10 einstückig angeformten und stufenförmig abgewinkelten Laschen 11 zusammengefaßt.FIG. 5 shows a modified embodiment of a carrier. The two band-shaped carriers 1 according to FIG. 1 are combined to form a U-shaped profile and are integrally formed on the narrow sides 9, 10 and have step-like angled tabs 11.
