<p><P>PROBLEM TO BE SOLVED: To provide a coil bobbin such that it is able to appropriately correspond with respect to two or more kinds of wiring components, having a different number of turns of wirings and creeping distances with one kind of the coil bobbin, and a transformer using the coil bobbin. <P>SOLUTION: For a coil bobbin, a coil 12 is installed around the outer circumference of a winding core section 17. The coil bobbin includes a first bobbin half 13a and a second bobbin half 13b; each bobbin half 13a and 13b is integrally provided with a flange (a terminal block 16a and an upper flange 16b), and at least two winding core pieces 17a and 17b projecting from the flange at right angles; and each winding core piece 17a and 17b is slidably incorporated into both bobbin halves 13a and 13b by turns, in a direction of mutual flange approach and a cylindrical winding core section 17 is formed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
