Abstract

The invention belongs to the technical field of inductor technologies, and provides a common mode inductor and a manufacturing method thereof. The common mode inductor comprises a magnetizer, end polepieces and two winding coils; the two winding coils are wound by flat wires, direct current resistance is reduced, the common mode inductor is not prone to heating when currents pass accordingly, rated currents of the common mode inductor are improved, and the requirements of low direct current resistance and the high rated currents of the inductor are met; leading-out terminals of the two winding coils and the end pole pieces are welded, the winding coils are wrapped with the magnetizer, the magnetizer and the winding coils are integrally formed, and the common mode inductor is high in strength and impact resistance capacity accordingly; the end pole pieces extend outside the magnetizer and form electrodes of the common mode inductor, and when the certain magnetic conductivity of the magnetizer is guaranteed, the temperature coefficient can be 180 DEG C, and the common mode inductor can work at the high temperature or the low temperature accordingly; the problems that an existing common mode inductor is poor in vibration resistance capacity and impact resistance capacity and cannot work in the high-temperature state are solved.

Description

technical field [0001] The invention belongs to the technical field of inductor manufacturing, and in particular relates to a common-mode inductor and a manufacturing method thereof. Background technique [0002] At present, the existing common mode inductors include a magnetic core and a coil. The magnetic core is a square structure formed by butting two U-shaped blocks. There are chamfers on the sides of the magnetic core, and the outer surface of the magnetic core is attached layer, the coils are respectively wound in the middle of the two U-shaped blocks. However, this kind of common mode inductor has weak anti-vibration and anti-shock capabilities, and cannot work under high temperature conditions. [0003] Therefore, the existing common mode inductors have the problems of weak anti-vibration and shock resistance, and cannot work under high temperature conditions. Contents of the invention [0004] The purpose of the present invention is to provide a common-mode ind...
