Abstract

A cordless charging apparatus is provided. The cordless charging apparatus includes a cordless power reception resonator including a feeding connector for electric feeding, and a ground connector for grounding. The ground connector is spaced apart from a connection terminal connecting the cordless power reception resonator to a circuit.

Claims

1. A cordless charging apparatus for supplying power to be stored by a battery, comprising:

a cordless power reception resonator including a feeding connector for electric feeding and a ground connector for grounding,

wherein the ground connector is spaced apart from a connection terminal connecting the cordless power reception resonator to a circuit.

2. The cordless charging apparatus of claim 1, wherein the connection terminal is disposed between the circuit and the wireless power reception resonator, the feeding connector is proximate to one side of the connection terminal, and the ground connector is formed at a location adjacent to a location of the connection terminal to be spaced apart from the connection terminal toward an opposite side of the connection terminal.

3. The cordless charging apparatus of claim 2, wherein the feeding connector and the ground connector are spaced apart from each other by at least 1 mm.

4. The cordless charging apparatus of claim 2, wherein an NFC module is installed on an inner side of the cordless power reception resonator, and a feeding point for supplying electric power to the NFC module is located adjacent to the connection terminal.

5. The cordless charging apparatus of claim 4, wherein the feeding point and the ground connector are spaced apart from each other by at least 1 mm.

6. A cordless charging apparatus for supplying power to be stored by a battery, comprising:

a cordless power reception resonator,

wherein a terminal of the cordless power reception resonator is spaced apart from connection ends of internal antenna modules disposed on an inner side of the cordless power reception resonator.

7. The cordless charging apparatus of claim 6, wherein the internal antenna modules comprise an NFC module.

8. The cordless charging apparatus of claim 7, wherein the cordless power reception resonator comprises a terminal line and a feeding line, and the cordless charging apparatus further comprises a circuit connected by a connection terminal to drive the cordless charging resonator.

9. The cordless charging apparatus of claim 8, wherein the terminal line is formed along a circumference of an NFC module such that opposite ends of the terminal line face each other on one side of the connection terminal, the feeding line is provided on an inner side of the terminal line, and terminals of the cordless power reception resonator are provided at opposite ends of the feeding line.

10. The cordless charging apparatus of claim 9, wherein the terminals of the cordless power reception resonator comprise:

a feeding connector disposed at one end of the feeding line and located adjacent to the one side of the connection terminal to supply electric power; and

a ground connector disposed at an opposite end of the feeding line and connected to the terminal line to be spaced apart from an opposite side of the connection terminal.

11. The cordless charging apparatus of claim 10, wherein the NFC module is mounted on an inner side of the feeding line and is connected to a circuit through a connection end of the NFC module mounted adjacent to the connection terminal.

12. The cordless charging apparatus of claim 11, wherein the feeding connector and the ground connector are spaced apart from each other by at least 1 mm.

13. The cordless charging apparatus of claim 11, wherein the ground connector is spaced apart from the connection terminal by at least 1 mm.

14. The cordless charging apparatus of claim 8, wherein the terminals of the cordless power reception resonator comprise:

a feeding connector disposed at one end of a feeding line for supplying electric power and mounted proximate to one side of the connection terminal; and

a ground connector disposed at an opposite end of the feeding line, connected to a terminal line provided at an outer circumference of the feeding line, and spaced apart from the connection terminal by at least 1 mm toward an opposite side of the connection terminal.
