PROBLEM TO BE SOLVED: To connect the secondary wire at the winding-stating end section of a secondary coil to the primary winding at the winding-ending end section of a primary coil without soldering. SOLUTION: A primary and secondary coil assembly is constituted in such a way that a supporting wall 25 which supports a conductive pin 22 by holding it with the wall 25 is provided, and a cut-out 31 is partially formed at the lower end of the wall 25 for partially exposing the horizontal portion 22' of the pin 22. Then the stopper flange 41 of a primary bobbin for a primary coil 40, which is made of an insulating material and stops the primary bobbin when the primary coil 40 is inserted into a secondary bobbin, is provided at the front end section of the primary bobbin, and a conductive piece 43 to which the winding-ending end section of the primary coil 40 is connected is attached to the flange 41. In addition, an engaging section 44 which engages the conductive piece 43 by getting into the slit section of the flange of the secondary bobbin on the winding-starting side when the primary coil 40 is inserted into the secondary bobbin is installed to the piece 43, and the winding-ending end section of the primary coil is electrically connected to the winding-starting end section of the secondary coil through the conductive pin 22 and piece 43 by inserting the primary coil 40 into the secondary bobbin for assembly. |
