Abstract
Coil formers having flanges selectedly removed at interface areas with a core can provide advantages of increase a winding window and better heat transfer. The coil former can also have added flanged adjacent to the core to provide added protection to the core. Examples of e-cores and PQ cores are shown.
Claims20
A coil former comprising:
- a tube comprising a winding surface,
- wherein the winding surface comprises a boundary edge with the boundary edge disposed on a flat surface and formed an end of the tube,
- wherein the winding surface is configured for winding a coil wire with a section of the coil wire contacting or disposing at a vicinity of the flat surface;
- a first flange coupled to a first portion of the boundary edge,
- wherein the first flange is extended from the first boundary edge portion for constraining the coil wire within the winding surface,
- wherein the first flange is configured to expose a portion of the coil wire section and a second portion of the boundary edge, with the portion of the coil wire section disposed on a first portion of the winding surface comprising the second boundary edge portion.

A coil assembly comprising:
- a coil former;
- a coil wire wound on the coil former and configured to generate a flow of magnetic flux;
- one or more cores coupled to the coil former and configured to improve the magnetic flux flow,
- wherein the coil former comprises
- a tube comprising a winding surface,
- wherein the winding surface is configured for the coil wire to contact or dispose at a vicinity of a boundary edge of the winding surface;

A coil former comprising:
- a tube comprising a winding surface,
- wherein the winding surface comprises a curve surface or a segmented surface comprising multiple flat or curve surfaces.
- wherein the winding surface is configured for the coil wire to contact or dispose at a vicinity of a boundary edge of the winding surface;
- a first flange coupled to the boundary edge,
- wherein the first flange is extended from the boundary edge for constraining the coil wire within the winding surface,
- wherein the first flange is configured to enable the one or more cores to be immediately adjacent to the coil wire,
- wherein the first flange comprises a first portion extending from the boundary edge in a direction comprising a component perpendicular to the winding surface comprising the boundary edge,
- wherein the first flange comprises a second portion extending from the boundary edge in a direction comprising a component parallel to the winding surface comprising the boundary edge,
- a second flange also coupled to the boundary edge,
- wherein the second flange is extended from the winding surface comprising the boundary edge in a direction comprising a component parallel to the winding surface,
- wherein the second flange is extended from the boundary edge to be parallel to a surface of a core of the one or more core,
- wherein the second flange is disposed adjacent to a surface of a core of the one or more cores with the core surface not adjacent to the coil wire,
- a support disposed inside the tube for supporting two separate portions of the winding surface,
- wherein the support comprises a third flange extending outside the tube end with a portion extended in directions comprising a component perpendicular to the two separate portions of the winding surface,
- a separator disposed on the surface along a periphery of the tube, with the separator configured to separate the coil wire from another coil wire.
