Magnetic assembly
View Patent ↗A magnetic assembly for mounting to a circuit includes a winding and a core. The winding has a first end, a second end and a wound portion. Further, the core is disposed around at least a portion of the winding. The first end of the winding extends outward from the wound portion to define a linear support and the second end of the winding extends outward from the wound portion on an opposite side of the wound portion to define a point support. As such, the first and second ends of the winding are adapted to mount to the circuit.
1. A magnetic device, comprising:
a circuit board having an upper surface, a lower surface and a mounting aperture therethrough between the first and lower surfaces;
a magnetic assembly positioned through the mounting aperture and mounted to the circuit board, wherein the magnetic assembly includes;
a winding having a first end, a second end and a wound portion; and
a core disposed around at least a portion of the winding, wherein:
the first end of the winding extends outward from the wound portion to define a linear support;
the second end of the winding extends outward from an opposite side of the wound portion to define a point support; and
wherein the linear support and the point support of the first and second ends mount onto the circuit board and support the assembly.
2. The magnetic device of claim 1 , wherein the linear support mounts to the circuit board along a line defined by at least two contacting points, and wherein the point support mounts to the circuit board on at least one contacting point.
3. The magnetic device of claim 1 , wherein the contacting points define a bounded geometry and wherein the centroid of the assembly is located within orthogonal projections of the bounded geometry.
4. The magnetic device of claim 1 , wherein the centroid of the assembly is located below the upper surface of the circuit board.
5. The magnetic device of claim 1 , wherein the second end of the winding has a convex curvature defining the point support.
6. The magnetic device of claim 1 , wherein the first end of the winding has a linear portion defining the linear support.
7. The magnetic device of claim 1 , wherein the core includes a ferrous material.
8. The magnetic device of claim 1 , the core comprises a first portion and a second portion, wherein the first and second portions are affixed to one another.
9. The magnetic device of claim 1 , wherein the core has at least one substantially flat surface adapted for engagement by a surface mounting apparatus.
10. The magnetic device of claim 9 , wherein the core has two opposing substantially flat surfaces.
11. The magnetic device of claim 1 , wherein a central portion of the core is positioned within the wound portion.
12. The magnetic device of claim 1 , wherein the core has side apertures along outer side edges of the core, the side apertures having the first end of the winding projecting therethrough and the second end of the winding projecting therethrough on an opposite side of the wound portion.
13. The magnetic device of claim 1 , wherein the magnetic device is reflow soldered to the circuit board.
14. The magnetic device of claim 1 , wherein the core is an RM-shaped ferrite core.
