Coil wire support element, manufacturing method thereof, and inductive power transfer coupler incorporating same

The invention relates to coil wire support elements, to manufacturing methods thereof, and to inductive power transfer couplers incorporating same. Such a coil wire support element comprises a support member for supporting a coil wire, a coil wire section formed of coil wire that is coiled on the support member in one or more coil wire layers, and a front and one back wall arranged at the respective ends of the support member and protruding from the support member in a radial direction for providing lateral support to parts of the at least one coil wire layer in one coil wire section, wherein the height of the at least one coil wire layer, coiled in said one coil wire section on the support member, is larger in the radial direction than the height of the segment of the front wall protruding in said radial direction from the support member.
