Abstract

The invention provides a novel inductor magnetic core. The novel inductor magnetic core comprises a first magnetic core, a second magnetic core and a columnar magnetic core, wherein the columnar magnetic core is connected between the first magnetic core and the second magnetic core, the first magnetic core, the second magnetic core and the columnar magnetic core are connected integratedly, at connection positions of the first magnetic core, the second magnetic core and the columnar magnetic core, the first magnetic core and the second magnetic core are provided with positioning holes, an end part of the columnar magnetic core is embedded into the positioning holes, gaps are arranged in the connection positions, and the hardness of an inductor is conveniently changed. The high-frequency inductor magnetic core integrates the advantages of space utilization rate and simple winding of a traditional combination inductor, the problems of magnetic leakage and difficulty in assembly and positioning also can be solved, meanwhile, the gaps are also convenient to adjust, and the hardness of the inductor is adjusted by adjusting the gaps.

Description

Technical field: [0001] The invention relates to a novel inductor magnetic core. Background technique: [0002] The inductance used in the industry was the earliest ring structure. The magnetic circuit of the ring inductor is closed, the heat dissipation is good, the space utilization rate is not high, and the winding is more complicated; the subsequent use of the combined inductor of the strip magnetic core or the track cylinder solves the problem of space and winding. However, there are problems such as magnetic flux leakage and difficulty in assembly and positioning. Invention content: [0003] The technical problem to be solved by the present invention is to provide a new inductance magnetic core, which not only integrates the advantages of space utilization and simple winding of ordinary combined inductance, but also solves the problems of magnetic flux leakage and difficult assembly and positioning. [0004] For this reason, the present invention adopts following te...
