Abstract

Systems and methods for implementing interengagement structures for a ferrite tile assembly of an induction coil housing are described herein. One aspect of the subject matter described in the disclosure is a housing. The housing includes a base forming a receptacle. The housing further includes a ferrite tile assembly. The housing further includes an interengagement structure extending from the base and configured to secure the ferrite tile assembly relative to the base within the receptacle.

Claims (26)

1. An induction coil housing comprising:

a base forming a receptacle configured to receive a ferrite tile assembly, at least one tile of the ferrite tile assembly having an opening; and

a pillar extending from the base and configured to be disposed in the opening so as to secure the ferrite tile assembly relative to the base within the receptacle.

2. The induction coil housing of claim 1 , further comprising an epoxy, the epoxy being disposed in the receptacle.

3. The induction coil housing of claim 1 , wherein the opening is disposed on a lower surface of the ferrite tile assembly.

4. The induction coil housing of claim 1 , further comprising a clip, the clip having a shaft extending from the base and a tang disposed on the end of the shaft.

5. The induction coil housing of claim 4 , wherein the tang is configured to contact an upper surface of the ferrite tile assembly.

6. The induction coil housing of claim 5 , wherein the clip is configured to contact a side surface of the ferrite tile assembly.

7. The induction coil housing of claim 6 , wherein at least one of the pillar and the tang is configured to support the ferrite tile assembly along a z axis.

8. The induction coil housing of claim 6 , wherein the pillar extends from the base at a different location than where the clip extends from the base.

9. The induction coil housing of claim 1 , wherein the pillar is configured to secure the ferrite tile assembly by biasing with a degree of elasticity.

10. The induction coil housing of claim 1 , wherein the ferrite tile assembly comprises multiple ferrite tiles.

11. A method for securing a ferrite tile assembly within a base of an induction coil housing, the method comprising:

providing a base forming a receptacle and having a pillar, the pillar extending from the base within the receptacle;

placing a ferrite tile assembly within the receptacle, at least one tile of the ferrite tile assembly having an opening; and

disposing the pillar within the opening so as to inhibit movement of the ferrite tile assembly in at least one direction relative to the base.

12. The method of claim 11 , wherein an epoxy is disposed within the receptacle.

13. An induction coil housing comprising:

a base forming a receptacle configured to receive a ferrite tile assembly, at least one tile of the ferrite tile assembly having an opening;

means for securing an upper surface of a ferrite tile assembly within the receptacle of the base;

means for securing a lower surface of the ferrite tile assembly within the receptacle of the base, the means for securing the lower surface comprising a pillar extending from the base and configured to be disposed in the opening; and

means for securing a side surface of the ferrite tile assembly within the receptacle of the base.

14. The induction coil housing of claim 13 , further comprising an epoxy, the epoxy being disposed in the receptacle.

15. The induction coil housing of claim 13 , wherein the opening is on a lower surface of the ferrite tile assembly.

16. The induction coil housing of claim 15 , wherein the means for securing the side surface comprises a shaft extending from the base, and wherein the means for securing the upper surface comprises a tang disposed on the end of the shaft.

17. The induction coil housing of claim 16 , wherein the tang is configured to contact an upper surface of the ferrite tile assembly.
