Abstract
An inductor comprises a ferromagnetic core, a litz wire conductor encircling the ferromagnetic core, a housing, a bobbin, a conductive pin, and a seal assembly. The housing encloses the ferromagnetic core and the litz wire conductor. The conductive pin is conductively attached to the litz wire conductor, and extends therefrom to form an external electrical contact. The bobbin supports the litz wire conductor and positions the conductive pin in alignment with an aperture in the housing which is sealed against fluid egress by the seal assembly.
Claims20
An inductor comprising:
- a ferromagnetic core;
- a litz wire conductor encircling the ferromagnetic core;
- a first conductive pin conductively attached to the litz wire conductor, and extending from the litz wire conductor to form an external electrical contact for the inductor;
- a housing enclosing the ferromagnetic core and the litz wire conductor, and provided with an aperture configured to accept the conductive pin;
- a bobbin configured to support the litz wire conductor and position the conductive pin in alignment with the aperture;
- and
- a seal assembly configured to seal the aperture against fluid egress from within the housing.
A sealed connection for a fluid-cooled inductor, the sealed connection comprising:
- a litz wire conductor encircling a ferromagnetic inductor core;
- a conductive pin conductively connected to and extending from the litz wire conductor;
- a housing enclosing the litz wire conductor, the housing having an aperture configured to accept the conductive pin;
- a seal assembly configured to seal the aperture against fluid egress from within the housing.
