Abstract
An improved structure of transformer includes a lead frame main body (1), a lead frame cover (2), a trouser-like flap (3), and two iron cores (4) where the lead frame main body (1) has a penetration hole (11) with a bobbin (12) formed at the circumference there around. The trouser-like flap (3) being made of metal has a hollow part (31) for slipping on a bobbin (121) of the lead frame main body (1) also includes horizontally stretched thigh parts (32), (33). The outer circumference of the trouser-like flap (3) is furnished with a primary winding (123). The lead frame cover (2) being a sheet-shaped body has a hollow hole (21) furnished at the center thereof. On the inner-side surface, each of the two iron core (4) has a main core part (41) capable of stretching through the penetration hole (11) of the lead frame main body (1) where the main core part (41) has a containing circumferential trench (43) capable of containing the lead frame main body (1). What is more, the containing circumferential trench (43) also has a pair of oppositely disposed side openings (44), (45) for being stretched through by the wire connecting seats (13), (14).
