Holes are formed in an upper magnetic core and a lower magnetic core, and the problem of positioning of winding column installation can be solved; the winding column is embedded into the positioning holes of the first magnetic core and the second magnetic core, and the problem of magnetic leakage of the inductor is solved; certain gaps exist between the upper strip-shaped magnetic core and the lower strip-shaped magnetic core of the inductor and the winding column, and relative balance is formed between inductor volume and inductance value of the inductor; and the hardness of the inductor is adjusted by adjusting the gaps, meanwhile, the space utilization rate of the inductor is improved, and installation and automatic winding operation are facilitated.

Description

Technical field: [0001] The present invention relates to a novel integrated inductor. Background technique: [0002] The first integrated inductor used in the industry is a ring structure, and the two windings are wound in two semicircles respectively, thereby forming two common magnetic core inductors. In this way, the magnetic circuit of the integrated inductor is closed, the heat dissipation is good, the space utilization rate is not high, and the winding is more complicated; the combined integrated inductor of the bar-shaped magnetic core or the track cylinder is used later, and the coils are wound on the sides of the two sides respectively. On the column, the space and winding problems are solved, but there are problems such as magnetic flux leakage and difficulty in assembly and positioning. Invention content: [0003] The purpose of the present invention is to provide a new type of integrated inductor, which not only integrates the advantages of space utilization a...
