Problems solved by technology
[0011] Therefore, the aforementioned Korean Patent Registration No. 10-2066735 of the PFC coil device and its manufacturing method has a technical limitation of poor workability when the coil execution process is performed on the bobbin.
[0012] In addition, the conventional technology is manufactured by winding wires, so the alignment of the coils is uneven, which leads to an increase in the space occupied by the coils, and the overall size is increased.

The present invention relates to a power factor correction coil assembly for a power panel of image equipment and a method for manufacturing the same, the power factor correction coil assembly comprising: a base plate (111) having a central hole (111a) formed in the center thereof; an insertion tube (112) formed so as to protrude upward along the inner peripheral edge of the center hole (111a) of the base plate (111); and a power factor correction coil group (200) that is disposed on the base plate (111), that is externally inserted into the insertion tube (112), and that compensates the power of an AC input power source, the power factor correction coil group (200) having an insertion hole (210) formed in the center thereof, the insertion hole (210) being externally inserted into and fixed to the insertion tube (112). The power factor correction coil group (200) forms a shaped form in which leads are welded to each other, thereby having the benefits of being able to reduce the size of a product and improve EMI characteristics.
Description
technical field [0001] The present invention relates to a power factor correction coil for a power board of an imaging device, and in more detail, relates to a power factor correction coil for a power board of an imaging device that can reduce production costs and man-hours, reduce the size of the product, and is suitable for improving EMI characteristics. Coil assembly and method of manufacturing the same. Background technique [0002] In general, video equipment such as TVs and display devices has a modular power board (power converter module) that converts the power supplied from a common power supply to the operating voltage of the corresponding video equipment. [0003] Moreover, recently, the power board of the video equipment is usually manufactured as a switching mode power supply (SMPS). [0004] The above-mentioned power board of the imaging device is formed with a power factor correction coil (PFC coil, power factor correction coil) for correcting the power of th...
