Abstract

A magnetic component is disclosed. The magnetic component includes a magnetic core assembly, a fastening element, a first winding set and a second winding set. The magnetic core assembly includes at least a pillar. The fastening element is provided on an outer peripheral surface of the pillar. The first winding set is disposed around the outer peripheral surface of the pillar. The second winding set is disposed around the outer peripheral surface of the pillar and engaged with the fastening set. The first winding set and the second winding set are located adjacent to each other and disposed around the outer peripheral surface of the pillar.

First claim

What is claimed is:

1. A magnetic component comprising:
a magnetic core assembly comprising a pillar, wherein the pillar comprises a groove inwardly recessed and located on an outer peripheral surface of the pillar;
a fastening set provided on the outer peripheral surface of the pillar and embedded in the groove of the pillar;
a first winding set disposed around the outer peripheral surface of the pillar; and
a second winding set disposed around the outer peripheral surface of the pillar and engaged with the fastening set.

2. The magnetic component according to claim 1 , wherein the fastening set comprises a first engaging portion and the second winding set comprises a hollow configured for receiving the pillar, and wherein the second winding set further comprises a second engaging portion located at a peripheral edge of the hollow configured to engage with the first engaging portion to define a space for a winding zone on the magnetic component.

3. The magnetic component according to claim 2 , wherein the first engaging portion comprises one or more protrusions and the second engaging portion comprises one or more recesses; or the first engaging portion comprises one or more recesses and the second engaging portion comprises one or more protrusions.

4. The magnetic component according to claim 2 , wherein the fastening set is elongate and extends parallel to a central axis of the pillar.

5. The magnetic component according to claim 2 , wherein the first engaging portion comprises a portion protruding outwardly from the outer peripheral surface of the pillar.

6. The magnetic component according to claim 5 , wherein the first engaging portion comprises a first positioning element, and the second engaging portion comprises a second positioning element, and wherein the first and second positioning elements are configured to engage with each other.

7. The magnetic component according to claim 2 , wherein the fastening set is a rod embedded in the groove, and the first engaging portion is disposed on an exposed surface of the rod.

8. The magnetic component according to claim 2 , wherein the fastening set includes a plurality of patched pieces embedded in the groove and spaced at intervals to define the one or more first engaging portions between each adjacent patched pieces, and wherein the first engaging portions is configured for engaging with the second engaging portion.

9. The magnetic component according to claim 1 , wherein a plurality of fastening sets embedded in a plurality of grooves are provided and arranged in arrays.

10. The magnetic component according to claim 2 , wherein the second winding set is a conductive thin plate comprising the hollow, and the first engaging portion comprises a buckle configured to attach to the peripheral edge of the hollow.

11. The magnetic component according to claim 1 , wherein the first winding set comprises a triple insulated coil, and the second winding set comprises a copper plate.

12. The magnetic component according to claim 1 , wherein the pillar comprises two end surfaces and the magnetic core assembly further comprises a first magnetic core and a second magnetic core, and wherein each of the first magnetic core and the second magnetic core is configured to connect with one of the two end surfaces of the pillar.

13. The magnetic component according to claim 1 , wherein the pillar comprises two end surfaces and the magnetic core assembly further comprises a first magnetic core and a second magnetic core, and wherein the first magnetic core is configured to connect with one of the two end surfaces of the pillar and the second magnetic core is configured to provide for an air gap between the second magnetic core and another one of the two end surfaces of the pillar.

14. The magnetic component according to claim 1 , wherein the first winding set and the second winding set are located adjacent to each other and disposed around the outer peripheral surface of the pillar.

15. The magnetic component according to claim 1 , wherein the magnetic component is a transformer, an inductor, or a filter.

16. A magnetic component comprising:
a magnetic core assembly comprising a pillar;
a fastening set provided on an outer peripheral surface of the pillar, and comprising a rib integral with the pillar, wherein the rib extends along and protrudes outwardly from the outer peripheral surface of the pillar;
a first winding set disposed around the outer peripheral surface of the pillar; and
a second winding set disposed around the outer peripheral surface of the pillar and engaged with the fastening set, wherein the second winding set comprises an indent configured to clasp the rib to effect an engagement of the second winding set with the fastening set.
