Abstract
The utility model discloses a magnetic core with thin epoxy coatings for a coil, and belongs to the technical field of magnetic material. The magnetic core comprises a magnet ring body, wherein, axial rectangular grooves are uniformly formed on the inner ring side of the magnet ring body along the circumference; rectangular pole shoes are respectively arranged on the grooves; the surfaces of the magnet ring body and the pole shoes are coated with the epoxy coatings; and the thickness of each epoxy coating is smaller than 1mm. By adopting the structure, the magnetic core has the advantages of simple technology, improved performance, higher production efficiency and cost reduction compared with the prior art.
Description
Technical field
The utility model relates to technical field of magnetic materials, particularly relates to a kind of thin epoxy coating coil magnetic core.
Background technology
At present, the coil magnetic core generally all applies the thick epoxy resin of 2mm, because epoxy coating is thicker; When curable epoxide, be easy to generate stress; And amorphous iron core counter stress is very responsive, causes the no-load loss of amorphous iron core and no-load current bigger, influences transformer 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 the oversized of iron core, and the cost of corresponding transformer is also higher.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, provides that a kind of technology is simple, performance improvement, production efficiency improves, cost reduces thin epoxy coating coil magnetic core.
The utility model comprises magnetic ring body; The ring side is evenly distributed with the rectangle axial notch along circumference in this magnetic ring body; Be respectively arranged with the cuboid pole shoe on each groove, be covered with one deck epoxy coating in the surfaces coated of magnetic ring body and pole shoe, the thickness of said epoxy coating is less than 1mm.
The thickness of said epoxy coating can be 0.3-0.9mm; The thickness of said epoxy coating is preferably 0.7mm.
The utility model compared with prior art has owing to adopt above structure: technology is simple, performance improvement, production efficiency improves, cost reduces advantage.
Description of drawings
Fig. 1 is the front view of the thin epoxy coating coil magnetic core of the utility model;
Fig. 2 is the left cutaway view of thin epoxy coating coil magnetic core shown in Figure 1.
Among the figure: 1, magnetic ring body, 2, pole shoe, 3, epoxy coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in the figure, it comprises magnetic ring body 1, and the ring side is evenly distributed with the rectangle axial notch along circumference in this magnetic ring body 1, is respectively arranged with cuboid pole shoe 2 on each groove, is covered with one deck epoxy coating 3 in the surfaces coated of magnetic ring body 1 and pole shoe 2.The thickness of said epoxy coating 3 is 0.7mm.
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.
