Patent number: 8854167Abstract: A magnetic assembly is formed by a Printed Circuit Board (PCB) and a cover. A plurality of magnetic elements is electrically disposed on the PCB, and the magnetic elements are connected to one another through an electric circuit on the PCB. An accommodation space is formed on the cover for receiving the magnetic elements. During the manufacturing of the magnetic assembly, a cover with an appropriate space is selected according to the size, quantity, and specification type of the magnetic elements. After the two components are assembled, adhesive is injected into the cover, so that the cover and the PCB are fixedly disposed, and the elements in the accommodation space are protected. Therefore, in a process of manufacturing the magnetic assembly, covers with different accommodation spaces are selected for collocation according to requirements of the assembled electrical elements.Type: GrantFiled: February 22, 2012Date of Patent: October 7, 2014Assignee: Mag.
