High-reliability and high-power chip type inductor

The invention provides a high-reliability and high-power chip type inductor, and belongs to the technical field of inductors. The high-reliability and high-power chip type inductor comprises magneticcores, annular coils and end pole pieces, wherein the annular coils are arranged in cavities of the magnetic cores; leading-out ends of the annular coils are led out through guide holes of the magnetic cores and are connected and communicated with the end pole pieces in a conduction manner; the annular coils concentrically cooperate with middle columns of the magnetic cores, and moreover, are mainly fixed in the cavities of the magnetic cores by means of the constraint effects of the magnetic cores. According to the high-reliability and high-power chip type inductor which is provided by the invention, as the middle columns of the magnetic cores are higher than magnetic walls, after two magnetic cores cooperate, an air gap exists between two magnetic walls. Through regulating the heights ofthe magnetic walls, the c
