摘要： A lead-frame structure (10) and a magnetic core structure (20) combined with lead-frame structure (10) are described. The lead-frame structure (10) includes a frame (11), a first metal terminal assembly (12), and a second metal terminal assembly (13). The frame (11) includes a first assembling portion (111) and a second assembling portion (112) spaced apart from each other. The first metal terminal assembly (12) is formed on the first assembling portion (111) and includes first terminals (121). The second metal terminal assembly (13) is formed on the second assembling portion (112) and includes second terminals (131). A top surface (121T) of each first terminal (121), a top surface (131T) of each second terminal (131), a top surface (111T) of the first assembling portion (111), and a top surface (112T) of the second assembling portion (112) are coplanar. The magnetic core structure (20) includes a body (21) combined with the above-described lead-frame structure (10). The body (21) provides convex beds (2122) to improve a positional accuracy of the first terminals (121) and the second terminals (131).

摘要： A magnetic core includes a winding core portion and two flange portions. The winding core portion is an octagonal cylinder. Two flange portions are respectively provided to two ends of the octagonal cylinder. Each of two flange portions has a top surface. One end of each of plural winding wires is connected to the top surface of one of two flange portions, and the other end of each of the winding wires is connected to the top surface of the other one of two flange portions. The octagonal cylinder has a first lateral surface and a second lateral surface adjacent to each other. The first lateral surface of the octagonal cylinder is parallel to the top surface of each of two flange portions. The area of the first lateral surface of the octagonal cylinder is less than the area of the second lateral surface of the octagonal cylinder.

摘要： A patch type transformer (2) includes a magnetic core (10) and four coils (S5, S6, S7, S8) wound around a winding portion (11) of the magnetic core (10). A first flange portion (12) and a second flange portion (13) of the magnetic core (10) are respectively connected to two ends of the winding portion (11). First to fourth pads (P1, P2, P3, P4) are sequentially arranged on the first flange portion (12) along a first direction (D1). Fifth to eighth pads (P5, P6, P7, P8) are sequentially arranged on the second flange portion (13) along a second direction (D2) opposite to the first direction (D1). Two ends of the first coil (S5) are respectively connected to the first pad (P1) and the seventh pad (P7). Two ends of the second coil (S6) are respectively connected to the third pad (P3) and the fifth pad (P5). Two ends of the third coil (S7) are respectively connected to the second pad (P2) and the eighth pad (P8). Two ends of the fourth coil (S8) are respectively connected to the fourth pad (P4) and the sixth pad (P6).
