Abstract
An inductive charging paddle includes a core and an electric wire, which is wound about the core to form a coil. The coil is connected to an electricity supplying apparatus through a cable. The electric wire includes a litz wire, a heat-shrinkable tubing, which coats substantially the entire length of the litz wire, and an insulating tube, which coats substantially the entire length of the heat-shrinkable tubing. A space is formed between the heat-shrinkable tubing and the insulating tube. As a result, the structure of the coil is simplified and the flexibility of the electric wire is maintained.
Claims18
A coil used in an inductive charging paddle, wherein a core is located in the paddle, and an electric wire is wound about the core to form the coil, and wherein the coil is connected to a power source through a cable, the electric wire comprising:
- a core wire;
- and
- a plurality of insulating members for multi-coating the core wire.
A coil used in an inductive charging paddle, wherein a core is located in the paddle, and an electric wire is wound about the core to form the coil, and wherein the coil is connected to a power source through a cable, the electric wire comprising:
- a litz wire, which is made of bundles of strands;
- a first insulating tube, which coats substantially the entire length of the litz wire;
- and
- a second insulating tube, which coats substantially the entire length of the first insulating tube.
