Impedance converting transformer formed of conductors extending through a magnetic housing

A transformer for converting an input signal to an output signal of different impedance comprising first and second conductors each being formed unitarily to have at least three overlap portions each having respective terminals at one end and an integral connection portion connecting the other ends of each of said overlap portions together;

• means including a member formed of insulating material and interposed between said first and second conductors electrically isolating said overlap portions of said first conductor from said overlap portions of said second conductor;
• and two discrete housing members each formed as a block of a magnetic substance and forming respective cores, at least one of said cores having three grooves;
• said overlap portions being placed in said grooves of said one core;
• said two cores being bonded to each other with said overlap portions between them to couple said overlap portions together electromagnetically, wherein said first and second conductors are arranged such that said connecting portions thereof do not superpose with each other.
