Abstract (en)

The mechanical connector (10) for the carrying hook, and the hearing aid, are made by powder injection molding, using a metal or ceramic powder. The connector and arm (18) to carry components, are made from the same material. They are made in one piece, as an integral component (16). The hearing aid casing is of multi-component construction. The mechanical connector and a section of the casing are made from the same material. The connector has a holder for a flexible tube connecting to a receiver, this comprises a pipe tail connector with ribs, or a self-cutting thread. The powder used in this method can be sintered. It is made of titanium or a an alloy. Alternatively, it is a ceramic powder, especially zirconium dioxide. An independent claim IS INCLUDED FOR the corresponding method of manufacture.

Abstract (de)

Zum Anschließen eines Hörgerätes an einen Tragehaken wird ein Verbindungselement eingesetzt, das hohen Anforderungen im Hinblick auf seine Genauigkeit und seine Stabilität gerecht werden muss. Um dies zu gewährleisten wird das Verbindungselement als Pulverspritzgussteil ausgeführt, insbesondere als Keramikspritzgussteil oder als Metallteil, das in einem Metal-Injektion-Molding-Prozess hergestellt wird.
