<p>PROBLEM TO BE SOLVED: To provide a power transformer compatible to both a pin type and a lead type, improve the connection work of the lead wires of the coil, and a less expensive transformer. SOLUTION: In a two-split bobbin provided with a primary side bobbin and a secondary side bobbin, lead wires of a coil are respectively connected with pin terminals planted on the bobbin and lead wires are also provided so as to be able to connect with the pin terminals so as be able to use the bobbin also as a lead type. In this case, linear parts are formed on the pin terminals so that wrapping can be executed on the pin terminals by an automatic wrapping machine and the points of the linear parts are bent for raising also the workability of a wiring of the lead wires to contrive to bind the lead wires onto the bent parts. Moreover, grooves for holding the lead wires are formed in the flange of the secondary side bobbin to stabilize the holding of the lead wires.</p> |
