Publication number: 20120154087Abstract: An isolation transformer including a magnetic element, a plurality of conductive elements and an insulative casing is disclosed. The magnetic element is accommodated in the insulative casing. The conductive elements are fastened in a pair of walls of the insulative casing. Each of the conductive elements has a plate, one end of which is divided into a first contact portion and a second contact portion. The second contact portion is further bent and in association with the first contact portion to form a slot for being passed through by a wire of the magnetic element. Thus the wire can be clipped by the two contact portions.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Inventor: Frank Chen
