Transformer with toroidal magnetic core

摘要

A transformer with a toroidal magnetic core. The toroidal magnetic core is housed in an insulating case. The insulating case has a top and bottom annular winding frames. These frames provide radial winding conductor grooves. The top annular winding frame provides a plurality of grooves for guiding an inter-connecting conductor therein each of which is formed between two adjacent winding conductor grooves. The inter-connecting conductor is guided through said guiding groove to connect between the adjacent two unit coils.
