Problems solved by technology

The traditional manufacturing method of one-piece inductors makes the production process of one-piece inductors complicated and inefficient, and the design space of the coil is reduced by embedding the lead frame in the soft magnetic metal powder, and the low pressing density of the soft magnetic metal powder cannot make the soft magnetic The metal powder fully exerts its material characteristics, and the cost of the lead frame is high. The electrode forming needs to be cut and bent, which wastes the material, and when the coil is put into the mold, it is impossible to ensure whether the coil can meet the process specifications required for the production of integrated inductors. The required position may cause the coil to be in a skewed state, resulting in a decrease in the product performance of the integrated inductor

Abstract

The invention relates to an integrally formed inductor and a manufacturing method thereof. The method comprises the following steps: placing a coil into a mold, and winding the coil into a preset shape; bending a lead wire of the coil to the mold; soft magnetic metal powder is added into the mold for pressing to obtain the integrally-formed inductor, so that the coil of the integrally-formed inductor is simple in structure and high in production efficiency, the production cost of the integrally-formed inductor is reduced, the design space of the coil can be increased, the pressing density of the soft magnetic metal powder is improved, and the production efficiency of the integrally-formed inductor is improved. The material characteristics of the soft magnetic metal powder are fully exerted, and it is guaranteed that the position of the coil in the magnetic core is not inclined.

Description

technical field [0001] The present disclosure relates to the technical field of integrally formed inductors, and in particular, to an integrally formed inductor and a manufacturing method thereof. Background technique [0002] Inductors mainly play the functions of filtering, oscillation, delay, and trapping in the circuit, as well as filtering signals, filtering noise, stabilizing current and suppressing electromagnetic wave interference. With the continuous development of inductor manufacturing technology, integrated inductors have appeared. Compared with traditional inductors, one-piece inductors have the characteristics of high current resistance and high temperature resistance, and the stability in the circuit is also particularly prominent, and the one-piece inductor molding is made of fully enclosed die-casting, so the one-piece inductor is formed. The volume is relatively small. [0003] In the traditional manufacturing method of integrally formed inductors, the coi...
