Coil block for wireless charging and method for manufacturing same

A method of manufacturing a coil block for wireless charging, the method comprising:

• configuring a shielding block including two lead holes for allowing two lead lines configured on a pattern coil to penetrate the lead holes;
• allowing the lead lines to penetrate the corresponding lead holes, respectively, to dispose the pattern coil on one surface of the shielding block;
• and
• attaching an adhesive member to a remaining surface of the shielding block,
• wherein an external support wall is formed on one surface of the shielding block along an external circumference of the shielding block, the two lead lines are guided to the two lead holes through an opening configured in one side of the external support wall, and a protrusion including the two lead holes is formed on the shielding block on an extension line of the opening.

A coil block for wireless charging comprising:

• a shielding block including two lead holes;
• a pattern coil disposed on one surface of the shielding block and including two lead lines penetrating the two lead holes;
• and
• an adhesive member attached to a remaining surface of the shielding block,
• wherein the shielding block includes:
• an external support wall formed on the one surface of the shielding block along an external circumference of the shielding block;
• an opening formed in one side of the external support wall and configured to guide the two lead lines to the two lead holes;
• and
• a protrusion including the two lead holes formed therein on an extension line of the opening.

A wireless power transmission apparatus comprising:

• a body;
• a transmission coil block installed in the body and configured to wirelessly transmit power;
• a transmitter control circuit board connected to the transmission coil block and configured to control power transmission;
• and

• wherein the transmission coil block includes:
• a shielding block including two lead holes;
• a pattern coil disposed on one surface of the shielding block and including two lead lines penetrating the two lead holes;
• and
• an adhesive member attached to a remaining surface of the shielding block;
• and
• wherein the shielding block includes:
• an external support wall formed on the one surface of the shielding block along an external circumference of the shielding block;
• an opening formed in one side of the external support wall and configured to guide the two lead lines to the two lead holes;
• and
• a protrusion including the two lead holes formed therein on an extension line of the opening.
