Der Spritzgusskörper kann mittels seiner Kontaktelemente auch zum Tragen elektronischer Bauelemente im Hörgerät verwendet werden. Dennoch sind zur Kontaktierung einiger Komponenten des Hörgeräts weitere Drahtverbindungen notwendig, die sich nicht als in den Kunststoffkörper eingespritzte Metallkontaktelemente realisieren lassen. The injection molded body can also by means of its contact elements used to carry electronic components in the hearing aid become. Nevertheless, some components are in contact of the hearing aid further wire connections necessary not as metal contact elements injected into the plastic body let it be realized.

Die Aufgabe der vorliegenden Erfindung besteht darin, die zur Kontaktierung notwendigen Elemente und Vorrichtungen zu miniaturisieren und deren Fertigung zu rationalisieren.The object of the present invention is that of Miniaturization of the necessary elements and devices and rationalize their manufacture.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Vorrichtung zum Kontaktieren elektrischer Bauelemente eines Hörgerätes mit einem Kunststoffspritzkörper zum Tragen von Kontaktelementen und mindestens einem Metallkontaktelement, das in den Kunststoffspritzgusskörper eingespritzt ist, sowie durch mindestens einem Verdrahtungselement, das leiterbahnartig auf der Oberfläche des Kunststoffspritzgusskörpers aufgebracht ist, zum Verdrahten der elektrischen Bauelemente und/oder des Metallkontaktelements.According to the invention, this object is achieved by a device for contacting electrical components of a hearing aid with a plastic injection molded body for carrying contact elements and at least one metal contact element, which in the plastic injection molded body is injected, and by at least one wiring element that is like a conductor track applied to the surface of the plastic injection molded body is for wiring the electrical components and / or the Metal contact element.

Darüber hinaus wird die oben genannte Aufgabe gelöst durch ein Verfahren zum Herstellen einer derartigen Vorrichtung durch Spritzgießen mindestens eines Strukturelements aus einem aktivierten Kunststoff, der insbesondere mit Palladium aktiviert ist, Einlegen des mindestens einen Strukturelements zusammen mit dem mindestens einen Metallkontaktelement in eine Spritzgussform, Umspritzen des mindestens einen Strukturelements und des mindestens einen Metallkontaktelements mit einem isolierenden Kunststoff zu dem Kunststoffspritzgusskörper, wobei das Strukturelement zumindest teilweise an die Oberfläche des Kunststoffspritzgusskörpers ragt, wodurch ein Oberflächenbereich definiert ist, und Metallisieren des durch das Strukturelement vorgegebenen Oberflächenbereichs des Kunststoffspritzgusskörpers.In addition, the above object is achieved by a method for manufacturing such a device by injection molding at least one structural element from a activated plastic, especially with palladium is activated, inserting the at least one structural element together with the at least one metal contact element in a Injection mold, overmolding of the at least one structural element and the at least one metal contact element with an insulating plastic to the plastic injection molded body, wherein the structural element at least partially protrudes the surface of the plastic injection molded body, whereby a surface area is defined, and metallizing the surface area predetermined by the structural element of the plastic injection molded body.

Verdrahtungselemente, die Leiterbahnen auf dem Kunststoffspritzgusskörper darstellen, können erfindungsgemäß nicht nur dafür verwendet werden, um eingespritzte Metallkontaktelemente miteinander zu verbinden, sondern auch dazu, Kontakte nach außen herzustellen. So ist es vorteilhaft, die Verdrahtungselemente mit Kontaktstellen auszustatten, die aus der Oberfläche des Kunststoffspritzgusskörpers herausragen und somit eine gute elektrische Kontaktmöglichkeit zu Bauelementen bieten, welche nicht mit federnden Metallkontakten gebildet werden müssen.Wiring elements, the conductor tracks on the plastic injection molded body represent, can not only according to the invention used to make injected metal contact elements to connect with each other, but also to make contacts to manufacture to the outside. So it is advantageous to use the wiring elements to be equipped with contact points from the Protruding surface of the plastic injection molded body and thus a good electrical contact possibility to components offer, which are not formed with resilient metal contacts Need to become.

Die Verdrahtungselemente beziehungsweise Leiterbahnen sind, falls zur Herstellung mit aktivierten Kunststoffstrukturelementen gearbeitet wird, über den Teilen der Strukturelemente angeordnet, die an die Oberfläche des Spritzgusskörpers ragen.

This can be a so-called In-the-ear hearing aid as well as a so-called behind-the-ear hearing aid act.

Die Herstellung der erfindungsgemäßen Kontaktvorrichtungen erfolgt vorzugsweise durch Einlegen entsprechender Kontaktelemente, die Metallkontaktelemente und Strukturelemente aus Kunststoff umfassen, in eine Spritzgussform, wie sie bereits eingangs als Insert-Mold Technologie vorgestellt wurde. Dazu werden zunächst die notwendigen Strukturelemente in ihrer dreidimensionalen Form aus einem beispielsweise mit Palladium aktivierten Kunststoff gespritzt. Anschließend werden diese gespritzten Strukturelemente zusammen mit den weiteren Metallkontaktelementen beziehungsweise Metallfedern in die Spritzgussform für den Gusskörper eingebracht. Daraufhin wird die Spritzgussform mit den Metallkontakt- und Strukturelementen mit isolierendem Kunststoff ausgespritzt. Schließlich werden die aktivierten Strukturelemente, soweit sie aus der Oberfläche ragen, beispielsweise in einem Bad mit Metall beschichtet.The manufacture of the contact devices according to the invention is preferably done by inserting appropriate contact elements, the metal contact elements and structural elements Include plastic in an injection mold like they already do was initially introduced as insert-mold technology.

Durch die Leiterbahntechnologie lassen sich in der Regel die Kontaktstellen, an denen Kontaktschwierigkeiten auftreten können, reduzieren, was zu einer Steigerung der Qualität der Kontaktvorrichtung führt. Weiterhin können im Falle der Herstellung mittels Insert Mold Technologie Einlegeteile eingespart werden, indem die Kontaktstellen für äußere Kontakte an die Strukturelemente angespritzt werden. Damit wird die Anzahl der für die Fertigung notwendigen Teile reduziert, womit sich auch die Montagezeit reduzieren und der Automatisierungsgrad für die Fertigung erhöhen lässt.The trace technology can usually be used Contact points where contact difficulties occur can reduce, resulting in an increase in the quality of Contact device leads. Furthermore, in the case of manufacture Insert parts saved using insert mold technology by contact points for external contacts the structural elements are molded. So the number the parts required for production, with what assembly time is also reduced and the degree of automation can be increased for production.

Eine Miniaturisierung ist, wie bereits erwähnt, auch dadurch möglich, dass Leiterbahnen auf den Spritzgusskörper aufgebracht werden. Hierzu können einerseits mit einem Laser diejenigen Stellen, die Leiterbahnen tragen, aktiviert, und anschließend die aktivierten Stellen auf dem Kunststoffkörper selektiv mit Metall beschichtet werden. Andererseits können die Leiterbahnen aber auch durch beliebige Druckverfahren auf den Spritzgusskörper aufgebracht werden.As already mentioned, miniaturization is also possible possible that conductor tracks are applied to the injection molded body become. For this, you can use a laser Places that carry traces activated, and then the activated areas on the plastic body be selectively coated with metal. On the other hand, you can the conductor tracks but also by any printing process the injection molded body can be applied.
