Wireless charger with connector
A wireless charging device includes a transmitter configured to transmit a power signal for wireless charging, a circuit board including at least one component configured to control an operation of the transmitter, a shielding plate configured to block an electrical interference between the transmitter and the circuit board, and a connector configured to penetrate through the circuit board and the shielding plate so as to electrically connect the transmitter with the at least one component.
1. A wireless charging device, comprising:
a transmitter configured to transmit a power signal for wireless charging;
a circuit board including at least one component configured to control an operation of the transmitter;
a shielding plate configured to block an electrical interference between the transmitter and the circuit board; and
a connector configured to penetrate through the circuit board and the shielding plate so as to electrically connect the transmitter with the at least one component,
wherein the connector comprises:
a lead wire guiding part configured to avoid that a lead wire prolonged from the transmitter strays;
a connection part configured to pass through the lead wire guiding part so as to be coupled with the lead wire; and
a fastening part configured to penetrate through the circuit board and the shielding plate.
2. The wireless charging device according to claim 1 , wherein the transmitter and the circuit board are arranged on front and rear sides of the shielding plate respectively.
3. The wireless charging device according to claim 1 , wherein each of the circuit board and the shielding plate includes plural holes where the connector is placed.
4. The wireless charging device according to claim 1 , wherein the lead wire guiding part, the connection part and the fastening part include the same conductive material.
5. The wireless charging device according to claim 1 , wherein the lead wire guiding part, unlike the connection part and the fastening part, includes a nonconductive material.
6. The wireless charging device according to claim 1 , wherein the connection part is a structure of a plane including a conductive material soldered with the lead wire.
7. The wireless charging device according to claim 1 , wherein the lead wire guiding part includes a groove where the lead wire is inserted.
8. The wireless charging device according to claim 7 , wherein the groove comprises:
a first part of which a width is same as a diameter of the lead wire; and
a second part of which a width is less than the diameter of the lead wire but flexible to get wider as the diameter of the lead wire,
wherein the second part includes a curved plane to reduce a frictional force when the lead wire is inserted.
9. The wireless charging device according to claim 1 , wherein the fastening part has a pin-type structure prolonged from the connection part, and wherein each of the connection part is extended into two fastening parts.
10. The wireless charging device according to claim 9 , wherein the fastening part comprises:
a body configured to penetrate through the circuit board and the shielding plate;
a deviation block part configured to avoid that the connection part deviates freely after fastened through the shielding plate; and
a movement block part configured to avoid that the connection part moves according to vibration after fastened through the shielding plate.
11. The wireless charging device according to claim 10 , wherein a thickness of the body is smaller than a diameter of a hole formed in the shielding plate.
12. The wireless charging device according to claim 11 , wherein the deviation block part and the movement block part are protruded or bent from the body in the opposite direction with each other.
13. The wireless charging device according to claim 11 , wherein a thickness of the fastening part including the deviation block part and the movement block part is larger in a plane dimension of the shielding plate than the diameter of the hole.
14. The wireless charging device according to claim 11 , wherein the hole formed in the shielding plate comprises:
a first portion having a diameter which is larger than a first thickness of the body, the deviation block part and the movement block part; and
a second portion having a diameter which is engaged with a second thickness of the body and the movement block part.
15. The wireless charging device according to claim 1 , wherein the circuit board is a printed circuit board (PCB) including a printed wire for connecting the at least one component with the connector.
16. The wireless charging device according to claim 1 , wherein the shielding plate comprises a soldering barrier configured to fix a soldering position when the transmitter is coupled with the connector by soldering and to block a leak of current to an external of the shielding plate.
17. The wireless charging device according to claim 1 , wherein the transmitter comprises at least one coil or antenna configured to transmit the power signal.
18. The wireless charging device according to claim 1 , wherein the shielding plate includes a material compounded from a Sendust and a Poly Amide.
