Abstract
A charging contact connection for a charger of an electrical device, in particular a hearing aid, includes a central contact pin for contacting a first counter-contact of a counter-contact connection, and a permanent-magnetic magnet element enclosing the contact pin for magnetically attracting the counter-contact connection. A contact element disposed on the front face facing the counter-contact connection guides and focuses the magnetic field of the magnetic element in the direction of a second counter-contact of the counter-contact connection. A charging contact system and an electrical device are also provided.
Claims16
A charging contact connection for a charger of an electrical device or a hearing aid, the charging contact connection comprising:
- a front face of the charging contact connection for facing a counter-contact connection having first and second counter-contacts;
