Claims14
A transformer, comprising:
- a first core comprising a first protrusion;
- a second core comprising a second protrusion facing the first protrusion;
- a bobbin interposed between the first and second cores, the bobbin comprising a cylindrical opening and a circumference;
- the cylindrical opening receiving at least part of the first protrusion at a first end and further receiving at least part of the second protrusion at a second end;
- a winding of at least one conductive wire around the circumference of the bobbin;
- a spacer rib placed within the cylindrical opening of the bobbin and interposed between the first protrusion and the second protrusion such that the spacer rib provides a gap between the first protrusion and the second protrusion without an adhesive material bonding and filling the gap between the first protrusion and the second protrusion.
