  • Publication number: 20240134111
    Abstract: The frame assembly has a first direction and comprises a first frame, which has at least one exhausting passage, an adhesive layer, which has at least one through hole, and a second frame, which is connected to the first frame via the adhesive layer. A containing space is defined by the first frame and the second frame together and extends along the first direction. The exhausting passage fluidly communicates with the containing space and the external environment. The adhesive layer is disposed inside the containing space to divide the containing space into two venting passages that fluidly communicate with each other through the through hole. Residue air in the containing space is evacuated through the exhausting passage, increasing an adhered area and adhesion completeness of the adhesive layer, thereby increasing an adhesion-bonding strength of the two frames and structural stability of the frame assembly.

  • Publication number: 20160181000
    Abstract: A magnetic element using a bank winding method is provided. The magnetic element includes a toroid core module and at least two winding coil assemblies. The toroid core module includes a magnetic core, at least two first position-limiting structures and at least two second position-limiting structures. The at least two winding coil assemblies are wound around the toroid core module. The at least two winding coil assemblies are separated from each other through the at least two first position-limiting structures. Moreover, two adjacent windings of a middle portion of each winding coil assembly are separated by a specified length through the corresponding second position-limiting structure.

  • Patent number: 8866578
    Abstract: A bobbin includes a first lateral plate, a second lateral plate, a winding section, a channel, a plurality of first pins and a plurality of second pins. A plurality of first protrusion structures are protruded externally from an edge of the second lateral plate. Each of the first protrusion structures includes an inner wall and a first notch. The inner walls of two adjacent first protrusion structures face each other and are separated from each other by a specified distance. The first notches of the first protrusion structures are respectively formed in the corresponding inner walls and staggered relative to each other. The first pins are disposed on the first protrusion structures, respectively. The second pins are disposed on the first protrusion structures, respectively. The first pins and the second pins are perpendicular to bottom surfaces of respective first protrusion structures.
