The partition wall 118 and the bottom of the partition 115 define an outgoing space S, and the first coil 13 and the second coil 14 are lined along the circumference of the boss 117 in the outgoing space S and electrically connected to the conductive pin 114. . In particular, the length of the bottom of the partition 115 is smaller than the distance that the connecting hole 119 extends to the partition wall 118 in the direction of the corresponding respective bosses 117 (please refer to FIG. 5 and is indicated by a broken line as a comparison reference between the length and the distance) . Referring to FIG. 5, in other words, for example, the boss 117 having the longest length (that is, the boss 117 having the entrance to the outlet space S) has a first edge E1 (ie, a dotted line), and is separated by The plate 115 is exemplified and has a second edge E1 that is closer to the partition wall 118 than the second edge E2.

In summary, the vertical transformer 1 and the wire frame 11 of the vertical transformer 1 are engaged with the engaging groove 116 by the partition 115 to extend the conductive pin 114 to the first coil 13 and the second coil 14. The face distance increases, and the length of the bottom of the partition 115 is smaller than the distance that the joint 119 extends in the direction of the corresponding boss 117 to the partition wall 118, and does not get stuck when the partition 115 is assembled. In addition, the design of the partition wall 118 in a concave shape can facilitate automated winding.
