Abstract
An inductive charging coupler for use in an inductive charging system comprising a charge port into which the coupler is inserted that minimizes damage to its magnetic core. The charging coupler comprises a housing, and a magnetic core disposed in the housing. A primary winding is disposed around the magnetic core. A current conductor is coupled to the primary winding for coupling current thereto. The magnetic core has plastic-ferrite covers disposed on opposite sides thereof. The plastic-ferrite covers are typically bonded to exterior flat surfaces of the magnetic core. The plastic-ferrite covers protect the ferrite core while preserving the magnetic properties of the coupler when it is inserted in the charge port. The plastic-ferrite material exhibits both plastic and ferrite properties and covers and protects the magnetic core in the coupler.
