PURPOSE:To realize common use of bobbin for radial or axial type transformer, reduce a number of parts and save the cost of metal molds by changing the position for implanting pin terminals in the same bobbin. CONSTITUTION:The pin holes for insertion of terminal pins 18 to which the lead wires are connected at the lower surface of the one collar 15 and the pin holes 19, 22 for insertion of terminal pins 18 to which the lead wires are connected at the side surface of the other collar 20 and the one collar 15. If a transformer providing, for example, small fitting area is required from the point of view of electrical characteristic and shape, an axial system coil can be formed by connecting lead wires to the terminal pins 18 implanted to the lower surface of the one collar 15. In case, on the contrary, if a transformer of lower height from the point of view of electrical characteristic and shape is required, a radial system coil can be formed by implanting the terminal pins 18 to the pin holes 19, 22 at the side surfaces of the other collar 20 and the one collar 15 and connecting the lead wires to the terminal pins 18. |
