Abstract: A transformer without matching sleeve for wire winding operation comprises a transformer wire frame, an iron core, a first winding unit and a second winding unit. The transformer wire frame comprises a winding part, a first wire outlet part and a second wire outlet part. The winding part comprises a first baffle, the second wire outlet part comprises a first inclined surface, a first partition plate, and a first block, the first partition plate divides the second wire outlet part into a first winding area and a second winding area, the first partition plate is only arranged corresponding to the first winding area. The first block is positioned in the first winding area to divide the first winding area into an initial winding area and a series winding area. Therefore, when the second winding is wound, the isolation requirement can be met without matching a sleeve.

The casing is provided with an accommodating groove at the connection side, each of the two conductive pins includes a power connection section located in the accommodating groove, an output section extending from the power connection section and passing through the casing to be exposed on the output side, and a capacitor connecting section extending from an end of the output section. Each of the conductive pins is provided with a through hole in the output section for disposing an electric wire, and the capacitor connecting section provides a capacitor pin to be connected thereon, so that the capacitor pin and the electric wire do not need to be disposed at a same hole position.

Abstract: The invention provides a transformer and a transformer bobbin thereof. The transformer bobbin includes a winding part, a first wire outlet part and a second wire outlet part; the second wire outlet part is provided with an inclined guiding surface facing the winding part, a first partition plate arranged on the inclined guiding surface and a wire avoiding groove arranged on one side of the inclined guiding surface; the inclined guiding surface is divided into a first wire outlet area and a second wire outlet area, the wire avoiding groove is only arranged in the first wire outlet area, and the first partition plate is formed with a wire supporting notch. Therefore, it is not necessary to add an insulation sleeve to windings at the same wire outlet part to achieve winding isolation, whereby windings on the transformer is automatically wound by a machine.

Abstract: A composite isolating transformer includes a main winding rack and a support rack. The main winding rack includes two winding portions coaxially formed to hold respectively a primary coil and a secondary coil, and a separating portion between the two winding portions. The support rack includes a first support half member and a second support half member coupling together to encase at least one winding portion. The first and second support half members have respectively a first cover and a second cover to cover two lateral sides of the winding portion, respectively a first insulating portion and a second insulating portion corresponding to the separating portion and extending towards the separating section to couple together, and respectively a first isolating portion and a second isolating portion extended from the first and second insulating portions towards the winding portion to cover another two lateral sides of the winding portion.

Abstract: An iron core winding assembly comprises a coil rack and an iron core structure coupled with the coil rack. The coil rack includes a winding portion, a through hole located in the winding portion and at least one lateral wire exit portion extended from the winding portion. The iron core structure includes two end walls and two axial magnetic cylinders located between the two end walls, and two top walls and two bottom walls located between the two end walls to cover the winding portion. Each axial magnetic cylinder runs through the through hole. Each top wall forms a wire exit notch with the bottom wall run through by the lateral wire exit portion. The iron core winding assembly thus formed is positioned transversely on an electronic baseboard at a desired height. By separating the winding portion and electronic baseboard via the bottom wall, electromagnetic interference can be avoided.
