Multiple conductive wire parallel winding construction for coil

The utility model discloses a multi-conducting wire parallel winding structure of a coil, which comprises more than k conducting wires which are connected in parallel and winded into a continuous or intertwined way. The structure is characterized in that the average number of turns of the conducting wires wound on the coil is n by round down, the total number of the conducting wires in the position where the conducting wires are wound in the amplitude direction of the coil and the number of the conducting wires is maximum can be arbitrary, i.e. the total number can not only be integral n times of the number of the parallel conducting wires, but also be kn plus 1, kn plus 2, to kn plus n minus 1, wherein, n is equal to 1, 2, 3, to infinity, and k is equal to or larger than 2, and is an integral. The multi-conducting wire parallel winding structure of the coil is applied to the transformer products of pie coil, and has the advantages that the size of the coil in the amplitude direction is easy to be adjusted, a
