TRANSFORMER INCLUDING BOBBIN WHERE PINS ARE ARRANGED AT MAXIMUM SPACING WITHOUT CAUSING CHANGES IN TOTAL ARRANGEMENT LENGTH OF PINS

摘要

PURPOSE: A transformer is provided to achieve improved withstand voltage characteristics between windings requiring insulation, by arranging pins at a maximum spacing without causing changes in total arrangement length of pins. CONSTITUTION: A transformer(100) comprises a core(110) integrally coupled to the center of a bobbin(120) wound with a coil; and a plurality of pins(130) arranged at a lower portion of the bobbin. The pins are grouped into two sections centering from the core such that the groups are symmetrical with each other and pins in the same direction are arranged in a zigzag manner.
