Abstract
The utility model discloses a CD (compact disc) type magnetic core which relates to the technical field of magnetic materials. The CD type magnetic core is provided with a magnetic core formed by overlying a plurality of chip bodies with one another in a transverse way, the entire surface of the magnetic core is packaged by an outer casing, a layer of epoxy coating is coated on the surface of the outer casing, and the thickness of the epoxy coating is less than 1mm. Compared with the prior art, as the above structure is adopted, the CD type magnetic core has the advantages of excellent performance, high production efficiency and low cost and is convenient to cut.
Description
Technical field
The utility model relates to technical field of magnetic materials, particularly relates to a kind of magnetic core.
Background technology
Make high-performance CD type magnetic core at present, mostly adopt winding method, form vertical lamination of " egg roll " shape, both be unfavorable for cutting processing, influence serviceability again; And magnetic core generally all applies the thick epoxy resin of 2mm, because epoxy coating is thicker, when curable epoxide, is easy to generate stress, causes no-load loss and no-load current bigger, influences performance; And thicker epoxy coating has increased curing time, causes production efficiency low, and delivery cycle is long; The epoxy coating that 2mm is thick makes oversized, and cost is also higher.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of CD type magnetic core that convenience, function admirable, production efficiency are high, cost is low that cuts is provided.
The utlity model has the magnetic core that laterally is formed by stacking each other a plurality of chip bodies, be inclusive with shell at the magnetic core integral surface, the surfaces coated of shell is covered with one deck epoxy coating, and the thickness of said epoxy coating is less than 1mm.
The thickness of said epoxy coating can be 0.4-0.6mm; The thickness of said epoxy coating is preferably 0.5mm.
The utility model is owing to adopt above structure, compared with prior art has cutting convenience, function admirable, production efficiency height, advantage that cost is low.
Description of drawings
Accompanying drawing is the structural representation of a kind of CD type of the utility model magnetic core.
Among the figure: 1, chip body, 2, shell, 3, epoxy coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Shown in accompanying drawing, it has the magnetic core that laterally is formed by stacking each other a plurality of chip bodies 1, is inclusive with shell 2 at the magnetic core integral surface, and the surfaces coated of shell 2 is covered with one deck epoxy coating 3; The thickness of said epoxy coating 3 is 0.5mm.
Above-described embodiment is more preferably one of embodiment of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included within the protection range of the utility model.
Claims (3)
1. a CD type magnetic core has the magnetic core that laterally is formed by stacking each other a plurality of chip bodies, it is characterized in that: be inclusive with shell at the magnetic core integral surface, the surfaces coated of shell is covered with one deck epoxy coating, and the thickness of said epoxy coating is less than 1mm.
2. CD type magnetic core according to claim 1 is characterized in that: the thickness of said epoxy coating is 0.4-0.6mm.
