Abstract: A transformer includes a magnetic core assembly, a bobbin, and a winding coil assembly. The magnetic core assembly includes a first magnetic core and a second magnetic core. Each of the first magnetic core and the second magnetic core includes a magnetic plate, a center leg, a first lateral leg, and a second lateral leg. The first lateral leg and the second lateral leg are disposed on two opposite edges of the magnetic plate. The magnetic plate has a thinned region. The thinned region is defined by the first lateral leg, the second lateral leg and the center leg collaboratively. The bobbin has an engaging structure corresponding to the thinned region. When the bobbin is arranged between the first magnetic core and the second magnetic core, the engaging structure of the bobbin is engaged with the thinned region. The winding coil assembly is wound on the bobbin.

Abstract translation: 变压器包括磁芯组件，线轴和绕组线圈组件。 磁芯组件包括第一磁芯和第二磁芯。 第一磁芯和第二磁芯中的每一个包括磁性板，中心腿，第一侧向腿和第二侧向腿。 第一侧腿和第二侧腿设置在磁板的两个相对的边缘上。 磁性板具有变薄的区域。 缩小区域由第一侧腿，第二侧腿和中心腿协同地限定。 线轴具有对应于变薄区域的接合结构。 当线轴布置在第一磁芯和第二磁芯之间时，线轴的接合结构与变薄的区域接合。 绕组线圈组件缠绕在线轴上。
