Holder for electric components

1. A holder for holding an electrical component comprising wire ends that act as electrical connections, the holder comprising:

a body comprising a center part, the center part comprising a recess for holding the electrical component, the recess comprising side walls, the side walls comprising slots for guiding wire ends of the electrical component;

first projections for winding wire ends, the first projections being on side surfaces of the body; and

second projections on the body between the slots and the first projections, the second projections for guiding wire ends;

wherein the recess and the slots are open at a same side of the body; and

wherein the body comprises a base, the base being an undivided part of the body and being on a different side of the body than the recess and the slots.

2. The holder of claim 1 , wherein a longitudinal axis corresponding to at least one of the first projections is substantially parallel to a plane containing a top side of the body.

3. The holder of claim 1 , wherein each of the first projections has a collar on a side facing away from the body; and

wherein a longitudinal axis of each collar is substantially perpendicular to a longitudinal axis of a corresponding first projection.

4. The holder of claim 1 , wherein a cross-section of each first projection has a shape that corresponds to a shape of a coil body.

5. The holder of claim 1 , wherein each first projection has a groove for guiding a wire end.

6. The holder of claim 1 , wherein a top edge of each first projection is substantially parallel to a top side of the body.

7. The holder of claim 1 , wherein ends of the slots extend beyond bottom edges of the first projections or the second projections.

8. An apparatus comprising:

a holder for holding an electrical component comprising wire ends that act as electrical connections, the holder comprising:

a body comprising a center part, the center part comprising a recess for holding the electrical component, the recess comprising side walls, the side walls comprising slots for guiding wire ends of the electrical component;

first projections for winding wire ends, the first projections being on side surfaces of the body; and

second projections on the body between the slots and the first projections, the second projections for guiding wire ends of the electrical component;

wherein the recess and the slots are open at a same side of the body; and

wherein the body comprises a base, the base being an undivided part of the body and being on a different side of the body than the recess and the slots; and

the electrical component;

wherein the electrical component does not extend beyond a top edge of the recess.

9. The apparatus of claim 8 ,

wherein a second projection is configured to guide a wire end of the electrical component between a slot and a first projection corresponding to the slot, the second projection for guiding the wire end substantially parallel to a base surface of the body.

10. The apparatus of claim 8 ,

wherein the second projections are configured to hinder upward slippage of the wire ends.

11. The apparatus of claim 8 , wherein each first projection comprises a groove for guiding a wire end; and

wherein a position of a first projection and a depth of a groove for the first projection are such that a top edge of a wire end extends beyond a top surface of the body and forms a contact for use in surface mounting the electrical component.

12. The apparatus of claim 8 , wherein the electrical component comprises a toroidal-core inductor comprising a wire winding; and

wherein the wire ends comprise ends of the wire winding of the toroidal-core inductor.

13. The apparatus of claim 12 , wherein the electrical component comprises a toroidal-core inductor comprising a closed magnetic core and two different wire windings.

14. The holder of claim 2 , wherein each of the first projections has a collar on a side facing away from the body; and

wherein a longitudinal axis of each collar is substantially perpendicular to a longitudinal axis of a corresponding first projection.

15. The holder of claim 14 , wherein first projections on different sides of the body have mirror-image constructions.

16. The holder of claim 15 , wherein each first projection has a groove for guiding a wire end.

17. The holder of claim 16 , wherein a top edge of each first projection is substantially parallel to a top side of the body.
