ABSTRACT:
A transformer winding form includes an insertion-type leader frame which is attached to the transformer winding form during the process of molding the winding form. The leader frame can be produced in a T-shaped or L-shaped configuration for attachment at the proper position on the transformer winding form. Due to a the lower curved section in the T-shaped leader frame, the thus equipped transformer winding form can be soldered firmly to a PC board, while also having horizontal side terminals which facilitates other connections to the transformer winding form. The horizontal side terminals of the T-shaped configuration also conform to the special layout holes of a PC board, as a result of which the overall height of the transformer winding form is also decreased. In the L-shaped leader frame, the lower vertical terminals underneath can also be inserted into the holes of a PC board and thereby comply with the requirements of large-volume output automatic soldering machines.
