A transformer (A BOBBIN CAPABLE OF RELIABLY INSULATING A FIRST COIL FROM A SECOND COIL) having a coil frame from which the first coil is reliably insulated from the second coil,

摘要

In the coil frame of the present invention having the first plate 55 and the second plate 57 located opposite the first plate, the first and second sleeves 59, And the first sleeve 59 is inserted into the second sleeve 61.;The split sleeve 63 is sandwiched between the first and second plates 55 and 57 and is wrapped around the first sleeve 59 and welded or bonded to the first plate 55. The first and second set connectors 51 and 53 are fixed to the coil frame. The first coil 43 is wound around the split sleeve 63 and is connected to the first set connector 51. The second coil 45 is wound around the second sleeve and connected to the second set connector 53 through the hole of the third plate. The split sleeve 63 may be integrally formed with the first plate 55. The first and second connecting arms 97 and 99 can be formed integrally with the first plate 55 and each connecting vertex of each connecting arm passes through the second and third holes of the second piece, Can contact the surface 73 of the plate. The first and second connection arms may penetrate the first and second flaws of the second plate. In this case, the split sleeve 63 contacts the first plate or the second plate.
