Abstract
A miniature transformer is provided at each end surface of a bobbin thereof with two spaced principal pins and two spaced dummy pins located between the two spaced principal pins. The dummy pin each is an integral extension from a rear end of an extended rear section of one adjacent principal pin embedded in the bobbin. The extended rear section extends obliquely forward toward a central area of the end surface of the bobbin and then turns straight forward to project from the end surface to form the dummy pin. The dummy pin each is provided at an inner side with a curved notch for a lead from windings on the miniature transformer to wind around there without further reducing a small distance between two adjacent dummy pins. Since the dummy pins are located between and shorter than the principal pins, they are protected by the principal pins without being easily touched or pulled to cause broken leads that would result in high bad yield in the production of the miniature transformer.
