上部より突出しないようにした構造としてある。 A protrusion 4 for planting pin terminals 7a and 7b in the axial direction on the circumferential side surface of the case 4 made of an insulating material.
A plurality of pin terminals 2a, 42b, 43a, 43b are provided symmetrically, and the pin terminals 7a, 7b are implanted by penetrating the center of the protrusion implanted in the insulating case, and the lower part of the pin terminal is the board insertion part, and the upper part is the board insertion part. Winding lead wire 6
It becomes solder part. In addition, the tip of the upper pin terminal is attached to the lid 3 when it is covered with the lid 3 made of an insulating material.
The structure is such that it does not protrude from the top.
