Insulation alement and toroidal core throttle
A toroidal core choke includes a toroidal core and an insulating part. The insulating part includes a separating device for separating winding spaces on the toroidal core. The separating device includes a divider and a spacer on an end of the divider. A width of the divider is less than a width of the spacer.
1. An insulating part for installation into a hole of a toroidal core, the insulating part comprising:
a separating device for separating winding spaces on the toroidal core;
wherein the separating device comprises:
a divider; and
a spacer on an end of the divider;
wherein the spacer comprises a spreading part, the spreading part being spreadable widthwise relative to the divider, wherein a width of the divider is less than a width of the spacer when the spreading part is spread, and wherein the divider comprises a first end and a second end that is away from the spreading part, the divider at least reaching a center point of the insulating part that is between the first end and the second end.
2. The insulating part of claim 1 , wherein the width of the spacer is greater than or equal to twice the width of the divider when the spreading part is spread.
3. The insulating part of claim 2 , wherein a radial length of the spreading part when spread is less than a spread width of the spreading part.
4. The insulating part of claim 3 , wherein the radial length is less than or equal to 0.4 times the spread width.
5. The insulating part of claim 4 , wherein the radial length of the spreading part when spread is less than a radial length of the divider; and
wherein the radial length of the spreading part is less than or equal to 0.5 times the radial length of the divider.
6. The insulating part of claim 1 , wherein the spreading part comprises elastically deformable spring elements that extend outwardly from the divider.
7. The insulating part of claim 1 , wherein the separating device is Y-shaped.
8. The insulating part of claim 1 , wherein the spacer comprises a first spacer, and the insulating part further comprises:
a second spacer on a second end of the divider, the second spacer comprising a spreader part that is usable as a support for the first spacer when inserted into the hole of the toroidal core.
9. The insulating part of claim 8 , wherein main surfaces of the spreader part of the second spacer form an angle between 60° and 120° relative to each other.
10. The insulating part of claim 1 , further comprising:
a second spacer on a second end of the divider.
11. The insulating part of claim 1 , wherein the separating device comprises one or more additional dividers, each of the one or more additional dividers comprising a spacer at an end thereof, the one or more additional dividers being interconnected in a star configuration.
12. The insulating part of claim 11 , wherein the divider and the one or more additional dividers are offset relative to each other by about an angle of 360°/n, where n is a total number of dividers.
13. The insulating part of claim 1 , which is formed in one piece.
14. The insulating part of claim 1 , which comprises an injection-molded part.
15. The insulating part of claim 1 , which contains a thermoplastic.
16. The insulating part of claim 1 , wherein the divider has no hollow spaces.
17. A toroidal core inductive device comprising:
a toroidal core; and
an insulating part comprising:
a separating device for separating winding spaces on the toroidal core;
wherein the separating device comprises:
a divider; and
a spacer on an end of the divider;
wherein the spacer comprises a spreading part, the spreading part being spreadable widthwise relative to the divider, wherein a width of the divider is less than a width of the spacer when the spreading part is spread, and wherein the divider comprises a first end and a second end that is away from the spreading part, the divider at least reaching a center point of the insulating part that is between the first end and the second end.
18. The toroidal core inductive device of claim 17 , wherein sections of the toroidal core on different sides of the divider are wrapped with a winding.
19. The toroidal core inductive device of claim 17 , wherein the divider projects past the toroidal core in an axial direction.
20. The toroidal core inductive device of claim 19 , wherein the divider projects past the toroidal core by at least 3 mm.
21. The toroidal core of claim 17 , wherein the divider has no hollow spaces.
