Abstract

A charging contact assembly for a hearing device system. The assembly has a first charging contact which is accessible on an outer side for contacting with a first mating contact of a mating contact assembly, and a second charging contact which is accessible on the outer side for contacting with a second mating contact of the mating contact assembly. Furthermore, the charging contact assembly has a control contact which is galvanically isolated on the outer side from the first and the second charging contacts, and a charging controller which is configured to detect a proper contacting of the first and second charging contacts with the corresponding mating contact based on contact with the control contact.

First claim

1 . A charging contact assembly for a hearing device system, comprising:
a first charging contact accessible on an outer side for contacting with a first mating contact of a mating contact assembly; a second charging contact accessible on an outer side for contacting with a second mating contact of the mating contact assembly; a control contact being galvanically isolated on an outer side from said first and second charging contacts; and a charging controller configured to cause a deactivation of a hearing device associated with said first and said second charging contact when said control contact is bridged to said first charging contact.

2 . The charging contact assembly according to claim 1 , wherein said control contact is positioned such that it is contacted by said first mating contact in a contacting state.

3 . The charging contact assembly according to claim 2 , wherein:
said first charging contact has a contact surface; and said control contact has a contact surface which is disposed at a same level as said contact surface of said first charging contact.

4 . The charging contact assembly according to claim 1 , wherein said control contact is set to high impedance.

5 . The charging contact assembly according to claim 2 , wherein said charging controller is configured to detect a bridging of said control contact to said first charging contact from a fact that said control contact is pulled to a different electrical potential.

6 . The charging contact assembly according to claim 1 , wherein said first charging contact and said control contact are disposed on a circular line around said second charging contact.

7 . The charging contact assembly according to claim 6 , wherein said contact surfaces of said first charging contact and of said control contact are each formed as a circular arc segment.

8 . The charging contact assembly according to claim 5 , wherein the different electrical potential is a potential to which said first charging contact is also connected.

9 . A hearing device, comprising:
said charging contact assembly according to claim 1 .

10 . A hearing device system, comprising:
a corresponding mating contact assembly; said charging contact assembly according to claim 1 ; a hearing device having said charging contact assembly or said corresponding mating contact assembly; and a charging unit conversely having said corresponding mating contact assembly or said charging contact assembly.
