Problems solved by technology
[0002] Electronic filters need to use a magnetic core with a complex shape, which often brings the problem that the blank is difficult to press and form, and requires the use of a special press with a complex structure, which is not conducive to mass production and greatly increases production costs
In addition, due to the complex shape of the product, the density of the blank is difficult to be uniform, and the product is easily deformed during sintering and becomes a waste product, which greatly reduces the product qualification rate, leads to high production costs, and brings a lot of waste to production.

Embodiment Construction
[0008] The core is composed of two semi-cylindrical cores. The magnetic core is sintered from ferrite material, or pressed from metal soft magnetic powder. The magnetic core can be pressed and formed with the simplest mold, and because of its simple shape, multiple pieces can be molded in one mold, which greatly improves production efficiency. The invention also effectively solves the problems that the traditional magnetic core is easily deformed and the qualified rate of products is low.

Description
technical field [0001] The invention relates to a magnetic core, in particular to a magnetic core for a filter. Background technique [0002] Electronic filters need to use a magnetic core with a complex shape, which often brings about the problem that the blank is difficult to press and form, and requires the use of a special press with a complex structure, which is not conducive to mass production and greatly increases production costs. In addition, due to the complex shape of the product, the density of the blank is difficult to be uniform, and the product is easily deformed during sintering and becomes a waste product, which greatly reduces the product qualification rate, leads to high production costs, and brings a lot of waste to manufacturing. In order to solve this problem, the magnetic core can be mass-produced at low cost by optimizing the design of the magnetic core structure.
