Abstract

Housing for electrical components includes a housing body, an insulating body and a bus bar. The insulating body is disposed within the housing body and is integral with the housing body. The bus bar is disposed within the within the housing body and embedded in the insulating body. The insulating body and housing body are integral with one another for fixing the bus bar within the housing body.

First claim

What is claimed is:

1. A housing for electrical components, comprising:
a housing body;
an insulating body disposed in and integral with the housing body; and
a bus bar embedded in the insulating body and integral with the housing body, the insulating body electrically insulating the bus bar from the housing and fixing bus bar within the housing,
wherein the housing includes a two or more interleaved foils interconnected to one another by a weld.

2. A housing as recited in claim 1 , wherein the housing body and the bus bar define respective standoffs for coupling electrical components in the housing.

3. A housing as recited in claim 1 , further including a cooling body connected to the housing body.

4. A housing as recited in claim 3 , wherein the cooling body is finned structure configured for cooling the housing using a gaseous coolant flow.

5. A housing as recited in claim 3 , wherein the coolant body is a cold plate configured for cooling the housing using a liquid coolant flow.

6. A housing as recited in claim 1 , further including a printed wire board disposed within and coupled to the housing body.

7. A housing as recited in claim 6 , further including a standoff embedded in the housing body and coupling the printed wire board to the housing body.

8. A housing as recited in claim 1 , further including an inductor body embedded within a cavity defined by at least one of the housing body and insulating body.

9. A housing as recited in claim 8 , wherein the inductor body is a C-shaped, E-shaped, Torrid or other shaped inductor.

10. A housing as recited in claim 8 , further including a conductor connected to the bus bar and winding about the inductor body.

11. A motor controller, comprising:
a housing as recited in claim 1 ;
a printed wire board disposed within the housing body;
a standoff electrically connecting the printed wire board to the bus bar, wherein the standoff mechanically couples the printed wire board to the housing body through the bus bar and insulating body; and
wherein the insulating body thermally connects the bus bar to the housing body for cooling the bus bar.

12. A motor controller as recited in claim 11 , wherein the housing body and insulating body are integrally formed using an additive manufacturing process.

13. A housing for electrical components, comprising:
a housing body;
an insulating body disposed in and integral with the housing body; and
a bus bar embedded in the insulating body and integral with the housing body, the insulating body electrically insulating the bus bar from the housing and fixing bus bar within the housing; and
a standoff embedded in the bus bar and coupling the printed wire board to the housing body.

14. A housing as recited in claim 13 , wherein the standoff electrically connects the printed wire board to the bus bar.

15. A housing as recited in claim 13 , wherein the standoff couples the printed wire board to the housing body through the insulating body.

16. A motor controller, comprising:
a housing as recited in claim 7 ;
a printed wire board disposed within the housing body; and
a standoff electrically connecting the printed wire board to the bus bar, wherein the standoff mechanically couples the printed wire board to the housing body through the bus bar and insulating body, wherein the insulating body thermally connects the bus bar to the housing body for cooling the bus bar, and wherein the housing includes a two or more interleaved foils interconnected to one another by a weld.
