Abstract:
A dummy pin structure for a miniature transformer, said miniature transformer including a bobbin having first and second oppositely disposed end surfaces and first and second principle pins projecting from each of said end surfaces, said dummy pin structure comprising first and second spaced dummy pins projecting from each of said first and second oppositely disposed end surfaces, said first and second dummy pins disposed between and parallel with said first and second principle pins, a first oblique section integrally formed with and connecting said first principle pin and said first dummy pin to form a generally U-shaped structure wherein said first oblique section forms an acute angle with said first principle pin and an oblique angle with said first dummy pin, a second oblique section integrally formed with and connecting said second principle pin and said second dummy pin to form a generally U-shaped structure wherein said second oblique section forms an acute angle with said second principle pin and an oblique angle with said second dummy pin and said dummy pins being shorter than said principle pins and each provided at an inner side with a curved notch for a lead from windings on said miniature transformer to wind therearound, and wherein each of said principle pins, dummy pins and oblique sections are formed from a flat plate and each of said principle pins being bent to form a riser for contacting a circuit board without causing the shorter dummy pins located between the principle pins to contact the circuit board.
