The assembly was consisted of two bobbins(9), (15), and the first bobbon (15) was large enough to the second bobbin(9). After winding the primary and the secondary coil separately, the core was inserted into center hole(10). The operations for winding the coils can be accomplished side by side, thus improving the working efficiency, and since the insulation laver between each coil is formed by the bonnin(15), another insulator is not necessary.
