<p><P>PROBLEM TO BE SOLVED: To provide a transformer that not only achieves easy mounting but also reduces the mounting area. <P>SOLUTION: The transformer includes a coil bobbin 3 having a cylindrical winding cylinder portion 2 wound by a winding 1 and core 7 comprised of an insertion portion inserted to be mounted in an inner hole 4 of the winding cylinder portion 2 of the coil bobbin 3 and non-insertion portion where there is provided a terminal mounting portion 9 on which a terminal 8 connected to each winding 1 on both ends in an axis direction of the winding cylinder portion 2 of the coil bobbin 3 is mounted. In the transformer, the terminal 8 is formed in L-shape comprising a mounting projection portion 10 which is projected to a lower direction to be mounted on a mounting surface and a winding connection projecting portion 11 which is projected to a lateral direction and to which the winding 1 is connected. Further, a terminal positioning portion for positioning the terminal 8 is disposed on the terminal mounting portion 9 by allowing a projecting direction of the winding connection projecting portion 11 of the terminal 8 to be a direction across the axis direction of the winding cylinder portion 2 in a planar view so that the winding connection projecting portion 11 is accommodated in a vertical projecting area of a non-insertion portion of the core 7 disposed around the winding cylinder portion 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
