Abstract: A magnetic core includes an ellipse-shaped central post and two side posts. The ellipse-shaped central post includes a long axis and a short axis. The length of the long axis is greater than the length of the short axis. The two side posts are disposed on two sides of the ellipse-shaped central post and opposite to each other. The two side posts are connected with the ellipse-shaped central post through two connecting portions respectively for defining at least one winding space with the ellipse-shaped central post. By utilizing the ellipse-shaped central post, the volume of the winding space is increased, the diameter of the wire of the winding coil can be increased, the temperature of the winding encapsulation is easy to be lowered, the over-volume issue of the winding encapsulation is avoided, and the safe distance between the bobbin and the winding encapsulation is increased, so that the present disclosure meets the safety regulation.
Abstract translation: 磁芯包括椭圆形中心柱和两个侧柱。 椭圆形中心柱包括长轴和短轴。 长轴的长度大于短轴的长度。 两个侧柱设置在椭圆形中心柱的两侧并且彼此相对。 两个侧柱分别通过两个连接部分与椭圆形中心柱连接，用于限定至少一个具有椭圆形中心柱的绕组空间。 通过利用椭圆形中心柱，绕组空间的体积增大，绕组线圈的直径可以增加，绕组封装的温度容易降低，容量过大的问题 避免绕组封装，提高绕线管和绕线封装之间的安全距离，使本公开符合安全规定。
