Contact device for hearing aids
View Patent ↗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.
1. 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.
2. The device according to claim 1 , wherein the at least tone metal contact element is a punched metal part.
3. The device according to claim 1 , wherein the at least one metal contact element is a metal spring.
4. The device according to claim 1 , wherein the at least one wiring element comprises at least one contact location for contacting an electrical component, the at least one contact location being raised over the surface of the injection molded plastic body.
5. The device according to claim 1 , wherein the at least one wiring element has a substrate that is a plastic section doped with palladium.
6. The device according to claim 1 , wherein two metal contact elements for contacting a hearing aid battery and a plurality of wiring elements for contacting a hearing aid electronics module are arranged at the injection molded plastic body.
7. A hearing aid comprising a device for contacting electrical components according to claim 1 .
8. The device according to claim 1 , wherein the device is a part of a hearing aid.
9. The device according to claim 1 , wherein the at least one wiring element is applied so that a metallic portion of the wiring element directly contacts the surface of the injection molded plastic body and is for some portion of its length parallel to the surface.
10. 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;
wherein the at least one wiring element comprises at least one contact location for contacting an electrical component, the at least one contact location being raised over the surface of the injection molded plastic body; and
wherein the at least one wiring element has a substrate that is a plastic section doped with palladium.
