摘要： A transformer with a modified cover and terminal portion of the coil bobbin to increase the creepage path between a terminal and a core, thus enhancing insulation performance. The invention discloses a cover on a coil bobbin, and includes a groove for increasing a creepage path which is formed in the high voltage side of a coil bobbin terminal portion with an embedded terminal. A projecting insulation wall which is inserted into the groove is formed inside the cover. A bent portion of the terminal is positioned on a lower side of the insulation wall. The transformer core is positioned on the upper side of the projecting insulation wall so as to improve the insulation performance and to allow for reducing or miniaturizing the height between the core and the bent portion of the terminal.
