变压器骨架
本专利技术涉及变压器骨架,特别涉及用于大功率AC-DC开关电源中能满足安规要求的电子变压器骨架。
技术介绍
现有AC-DC开关电源变压器骨架一般由带中心孔的绕线柱和端子台组成。如图1所示,包括带中心孔的绕线柱01、沿绕线柱01两端向外延伸而成的上挡板02和下挡板03;上挡板02两侧对称设置有左定位板04和右定位板05,左定位板04和右定位板05延上挡板02垂直向上延伸并呈类“V”形结构;下挡板03两侧对称设置有初级端子台06和次级端子台07,初级端子台06下表面间隔均匀地垂直设有端子08,次级端子台07下表面间隔均匀地垂直设有端子09。此种骨架由于左右对称,模具简单,因此为市场公模产品,采购容易,但由于左定位板04和右定位板05呈类“V”型结构、浪费了绕线柱01的中心孔所装磁芯的横截面积,导致装配的磁芯面积小、磁通量不能最大化,使得变压器的功率在限定的体积内不能最大化,不利于产品小型化。如图2所示,为另一种现有变压器骨架,与图1不同之处在于上挡板02两侧对称设置的左定位板04和右定位板05延上挡板02垂直向上延伸并呈长方形结构。该电子变压器骨架绕制利兹 ...
