Abstract
For miniaturizing and rationalizing the manufacturing process of contact devices for herring aids, it is proposed that an injection molded body be provided with metal contact springs according to the insert mold technology. Over and above this, wiring elements are applied on the injection molded body as interconnects. To this end, the injection molded plastic body provided with metal springs can be activated in specific patterns with, for example, a laser, and, subsequently, the activated portions are coated with conductive metal. Alternatively, the interconnects can also be printed onto the injection molded body.
Claims10
A device for contacting electrical components of a hearing aid, comprising:
- contact elements;
- an injection molded plastic body configured to carry the contact elements;
- at least one metal contact element of the contact elements that is injected into the injection molded plastic body;
- and
- at least one wiring element that is applied onto a surface of the injection molded plastic body in an interconnect-like manner for wiring at least one of the electrical components and the at least one metal contact element.
A method for manufacturing a device for contacting electrical components of a hearing aid, comprising:
- injection molding at least one structure element comprising an activated plastic that is activated with palladium;
- placing the at least one structure element together with at least one metal contact element into an injection mold;
- injection molding around the at least one structure element and the at least one metal contact element with an insulating plastic to form an injection molded plastic body, the structure element projecting at least partly to a surface of the injection molded plastic body, thereby defining a surface region;
- and
- metallizing the surface region of the injection molded plastic body defined by the structure element.
A method for manufacturing a device for contacting electrical components of a hearing aid, comprising:
- placing at least one metal contact element into an injection mold for the injection molded plastic body;
- filling the injection mold with an insulating plastic;
- irradiating an interconnect pattern on a surface of the injection molded plastic body;
- and
- coating the irradiated pattern with a conductive metal.
A method for manufacturing a device for contacting electrical components of a hearing aid, comprising:
- placing at least one metal contact element into an injection mold for the injection molded plastic body;
- filling the injection mold with an insulating plastic;
- and
- printing interconnects onto the injection molded plastic body.
