WIPO Patent Application WO/2015/135325

Kind Code:

A1

Abstract:

A conical inductor, a printed circuit board and an optical module. The conical inductor (50) comprises: a housing (501), a conical coil (502) in the housing and two pins (503, 504) respectively connected with both ends of the conical coil; wherein one end of the first pin (503) is connected with one end of the conical coil, and the other end of the first pin is fixedly connected with the hole (5015) in a first side wall (5012); one end of the second pin (504) is connected with the other end of the conical coil, and the other end of the second pin is fixedly connected with the hole (5016) in a second side wall (5013); each of the first pin and the second pin comprises a waveform section fluctuating along the vertical direction of a top wall, and each trough in the waveform section is fixedly connected to the printed circuit board. By changing the pins of the conical inductor, the accuracy of alignment between the pins of the conical inductor and the welding pads of the printed circuit board is increased, and meanwhile virtual welding of the conical inductor is reduced.
