Die Erfindung betrifft eine Vorrichtung zum Kontaktieren von in Kunststoff zu vergießenden elektrischen Bauelementen, insbesondere in Reihen angeordneten, röhrenförmigen, von der Tintenaustrittsöffnung strahlenförmig wegfiuchtenden piezoelektrischen Wandlerelementen, ~s Schreibköpfen von Tintenschreibeinrichtungen.The invention relates to a device for contacting in plastic Electrical components to be potted, especially those arranged in rows, tubular piezoelectric ones that radiate away from the ink outlet opening Transducer elements, writing heads of ink writing devices.
Aus der DT-OS 25 43 451 ist ein piezoelektrisch betriebener Schreibkopf für Tintenmosaikschreibeinrichtungen bekannt, bei dem die piezoelektrischen Wandlerelemente in Reihen von der Tintenaustrittsöffnung strahlenförmig wegfluchtend angeordnet sind. Jedes einzelne dieser Wandlerelemente ist mit einem im Kopf vergossenen Stekker verbunden, wobei die Verbindungen Uber einzelne Litzen hergestellt werden. Diese Litzen werden zuerst an den losen Keramikröhrchen angelötet und nach dem Einlegen der Wandler in die Gießform mit dem Stecker verlötet. Dazu sind Vorbereitungen notwendig, wie Zuschneiden der Litzen auf verschiedene Längen, .Sbisolieren und Verzinnen der Drahtenden vor dem Verlöten mit den Wandlern sowie richtige Plazierung der Wandler in der Gießform entsprechend der verschiedenen Längen und Farben der Litzen. Außerdem müssen die Röhrchen so ausgerichtet werden, daß benachbarte Lötpunkte nicht in Berührung kommen. Ehe die einzelnen Litzen mit dem Stekker verlötet werden, erfolgt der Anschluß der Innenkontakte der Röhrchen, indem man die Enden der eingesetzten Drahtwendeln zu einem gemeinsamen Steckerstift führt und verlötet.From the DT-OS 25 43 451 a piezoelectrically operated write head is known for ink mosaic writing devices in which the piezoelectric transducer elements arranged in rows aligned radially away from the ink outlet opening are. Every single one of these transducer elements has a plug encased in the head connected, whereby the connections are made via individual strands. These Litz wires are first soldered to the loose ceramic tubes and after inserting them the transducer is soldered into the mold with the connector. Preparations are necessary for this, such as cutting the strands to different lengths, stripping and tinning the Wire ends before soldering to the transducers and correct placement of the transducers in the mold according to the different lengths and colors of the strands. aside from that the tubes must be aligned so that adjacent solder points do not touch come. Before the individual strands are soldered to the connector, the connection is made the inner contacts of the tubes by removing the ends of the inserted wire coils leads to a common connector pin and soldered.
Werden derartige Schreibköpfe für Tintenschreibeinrichtungen in großen Serien hergestellt, so ist eine derartige Verdrahtung der einzelnen Wandlerelemente mit dem Stecker vor dem Vergießen kostspielig und zeitraubend.Are such writing heads for ink writing devices in large Manufactured in series, this is the wiring of the individual transducer elements with the plug before potting is costly and time consuming.
Aufgabe der Erfindung ist es, eine Vorrichtung zum Kontaktieren von in Kunststoff zu vergießenden elektrischen Bauelementen, insbesondere piezoelektrischen Wandlerelementen in Schreibköpfen von Tintenschreibeinrichtungen bereitzustellen, die es ermöglicht, die einzelnen Wandlerelemente mit einem ebenfalls im Schreibkopf vergossenen gemeinsamen Anschlußelement, leicht, kostengünstig und kurzschlußsicher zu verlöten.The object of the invention is to provide a device for contacting Electrical components to be cast in plastic, in particular piezoelectric components To provide transducer elements in writing heads of ink writing devices, which makes it possible to use the individual transducer elements with one also in the write head encapsulated common connection element, light, inexpensive and short-circuit proof to solder.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß für jede Wandlerreihe eine flexible, die Wandlerelemente mit einem gemeinsamen Anschlußelement für alle Wandlerelemente verbindende, Kontaktdurchbrüche aufweisende Leiterfolie vorgesehen ist.This object is achieved according to the invention in that for each A flexible converter series, the converter elements with a common connection element for all transducer elements connecting, contact openings having conductor foil is provided.
Bei einer vorteilhaften Ausführungsform sind am Rand der Leiterfolie Kontaktschlitze zur Aufnahme von die Innenelektrode der Wandlerelementen kontaktierenden Leitungen angeordnet.In an advantageous embodiment, the conductor foil is on the edge Contact slots for receiving the transducer elements contacting the inner electrode Lines arranged.
Die Erfindung hat den großen Vorzug, daß damit in einfacher und kostengünstiger Weise die einzelnen Wandlerelemente mit einem gemeinsamen, ebenfalls im Schreibkopf zu vergießenden Stecker verbunden und kontaktiert werden können. Dazu ist für jede Reihe von Wandlern eine Leiterfolie vorgesehen, die vorher mit dem Stekker verbunden und anschließend über die jeweilige Wandlerreihe gespannt wird. Die Folien enthalten durchbrochene Kontaktpunkte, durch die hindurch die Lötverbindung mit der Mantelfläche der röhrchenförmigen Wandler entsteht. Die Montagezeit des gesamten Schreibkopfes wird damit außercrdentlich verkürzt, zumal die Verwechslungsgefahr der Drähte beim Anlöten in der Gießform beseitigt ist.The invention has the great advantage that it is simpler and less expensive Way the individual transducer elements with a common one, also in the write head to be potted connector can be connected and contacted. This is for everyone Series of transducers provided a conductor foil, which was previously connected to the plug and then stretched over the respective transducer row. The slides contain perforated contact points through which the soldered connection to the jacket surface the tubular transducer is created. The assembly time of the entire print head is thus extremely shortened, especially since the danger of confusing the wires with Soldering in the mold is eliminated.
Eine Ausqührungsform der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden beispielsweise näher beschrieben.An embodiment of the invention is shown in the drawings and is described in more detail below, for example.
Es zeigen: Fig. 1 eine schematische Darstellung der flexiblen Leiterfolie, Fig. 2 einen Schreibkopf für eine Tintenschreibeinrichtung mit eingebauter Leiterfolie und Stecker, Fig. 3 einen Vertikalschnitt durch den Schreibkopf, Fig. 4 einen Horizontalschnitt durch den Schreibkopf und Fig. 5 einen Schnitt durch ein einziges Piezowandlerelement mit aufgelöteter Leiterfolie.They show: FIG. 1 a schematic representation of the flexible conductor film, Fig. 2 a writing head for an ink writing device with a built-in conductor foil and connector, FIG. 3 is a vertical section through the writing head, FIG. 4 is a horizontal section through the write head and FIG. 5 shows a section through a single piezo transducer element with soldered-on conductor foil.
Die Vorrichtung zum Kontaktieren von im Kunststoff zu vergießenden piezoelektrischen Bauelementen für Tintenschreibeinrichtungen besteht aus einer blattförmigen flexiblen Leiterfolie 1 mit Kontaktdurchbrüchen 2 zum Anlöten an die Wandlerelemente 3 und weiteren Kontaktdurchbrüchen 4 zum anlöten an ein gemeinsames Anschlußelement, in diesem Fall einen in den Kopf eingegossenen Stecker 5.The device for contacting plastic to be cast piezoelectric components for ink pens consists of a sheet-shaped flexible conductor foil 1 with contact openings 2 for soldering to the Converter elements 3 and further contact openings 4 for soldering to a common one Connection element, in this case a plug 5 cast into the head.
Am Rand der Leiterfolie 1 sind Kontaktschlitze 6 zur Aufnahme von die Innenelektrode 7 der Wandlerelemente kontaktierenden Leitungen 8 angeordnet.At the edge of the conductor foil 1 are contact slots 6 for receiving the inner electrode 7 of the transducer elements contacting lines 8 arranged.
Im einzelnen geschieht die Kontaktierung und das Vergießen der Wandlerelemente wie folgt: Für jede Reihe von Wandlern 3 ist eine Leiterfolie 1 vorgesehen, die vorher mit dem Stecker 5 verlötet und dann über die jeweilige Wandlerreihe gespannt wird. Durch die in der Folie 1 enthaltenen Kontaktpunkte 2 können die Leitungen der Leiterfolie 1 mit der Mantel fläche der Wandlerröhrchen gemäß der Darstellung in der Fig. 5 verlötet werden. Der Anschluß der Nullleiter geschieht dadurch, daß die Enden 8 der die Innenelektrode 7 der Wandlerelemente kontaktierenden Drahtwendel 9 in die Konaktschlitze 6 der Leiterfolie eingeführt und darin verlötet werden. Dieses Einführen der Drahtenden 8 der Drahtwendel 9 dient gleichzeitig zur Lagefixierung der Wandlerelemente auf der Leiterfolie. Die Leiterfolie selber, die aus elastischem isolierenden Kunststoff besteht, ist so ausgeführt, daß das Teilstück 10, das keine Leiterbahnen 11 enthält, als Zwischenlage dient und somit die als Außenelektroden dienenden Mantelflächen der Wandlerelemente 3 an der Stelle 10 voneinander isoliert, an der sie den geringsten Abstand zueinander haben.In detail, the contacting and potting of the transducer elements takes place as follows: For each row of transducers 3, a conductor foil 1 is provided which previously soldered to the connector 5 and then stretched over the respective transducer row will. Through the contact points 2 contained in the film 1, the lines the conductor foil 1 with the jacket surface of the transducer tube as shown 5 are soldered. The connection of the neutral wire is done in that the ends 8 of the wire helix contacting the inner electrode 7 of the transducer elements 9 are inserted into the contact slots 6 of the conductor foil and soldered therein. This introduction of the wire ends 8 of the wire helix 9 also serves to fix the position the transducer elements on the conductor foil. The conductor foil itself, which is made of elastic insulating plastic is made so that the section 10, which no Contains conductor tracks 11, serves as an intermediate layer and thus as external electrodes serving lateral surfaces of the transducer elements 3 isolated from one another at point 10, at which they are the closest to each other.
Die Verwendung von Leiterfolien ermöglicht das Vormontieren und Verlöten der Wandlerelemente 3 mit dem Stecker 4 außerhalb der Gießform. Dadurch wird die Montagezeit wesentlich verkürzt, das Bestücken der Gießform vereinfacht und die bisherige Verwechslungsgefahr der Litzen beim Anlöten vermieden.The use of conductor foils enables pre-assembly and soldering the transducer elements 3 with the plug 4 outside the Casting mold. This significantly shortens the assembly time and simplifies the loading of the casting mold and the previous risk of confusing the strands when soldering them is avoided.
