Abstract
The magnetic core and electrical coils of a multiple phase inductor are held together by a non-magnetically permeable retainer. The retainer has a base with a cavity that receives the magnetic core and has U-shaped arms that form channels which guide and align the components during assembly. A retainer cap snaps onto the base in a manner that retains the core elements and electrical coils. An electrical terminal block also snaps onto the cap for easy assembly.
Claims25
An electrical inductor assembly comprising:
- a core of magnetically permeable material;
- at least one electrical coil mounted on the core;
- and
- a retainer of non-magnetically permeable material, wherein the retainer comprises a base and a cap, wherein the base has a cavity in which the core is received, and the cap is fastened to the base thereby retaining the core in the cavity and retaining each electrical coil on the core;
- wherein the base has a body from which a plurality of arms extend along the core;
- and
- wherein each of the plurality of arms extends through one of the at least one electrical coil.
