Abstract

The invention discloses a folded forming coil, an ultra-low resistance power inductor made by the coil and a processing method of the inductor. The folding forming coil is formed by folding a whole piece of metal sheet, including the utility part and the pin part, and the pin part is connected to both ends of the utility part; The turning position between the segments is tortuous transition, and the equivalent number of turns of the utility part is 3 / 4; in the utility part, at least one lateral edge position of the connecting segment is connected with a folded segment, and each segment of the folded segment is folded and tightly closed at least once. It is attached to the outer peripheral side of the connecting segment connected to it. The invention not only improves the maximum current that the inductance device can withstand, greatly reduces DCR, and improves the stability of use, but also makes the coil structure inside the inductance device simpler, and provides convenience for the processing of the inductance device and its miniaturization application.

Description

technical field [0001] The invention relates to a related processing technology of a power inductor, in particular to a folded forming coil, an ultra-low resistance power inductor made by using the coil, and a processing method of the inductor, belonging to the technical field of inductor processing.
