ABSTRACT:
An inductive charging coupler for use in an inductive charging system that minimizes damage thereto caused by shock. The charging coupler comprises a housing, and a magnetic core disposed in the housing that is comprised of a plurality of sections. A primary winding is disposed around the magnetic core, A current conductor is coupled to the primary winding for coupling current thereto. By employing smaller sections of ferrite material to form the magnetic core, there is less potential for encountering broad differences in the crystal structure of the ferrite material. These structural differences can cause the ferrite material to be more prone to crack or shatter under stress conditions, such as if the coupler is dropped during use. Also smaller ferrite pieces are lighter than a single piece of ferrite material, which causes lower distributed loads due to a shock. In addition, smaller ferrite pieces allow more surface area contact with housing components or adhesives used to secure the core in the coupler and help dampen shock loads.
