US Patent:

56342624, Jun 3, 1997

Filed:

Jun 9, 1995

Appl. No.:

8/489092

Inventors:

Patricia A. O'Donnell - Davidsonville MD
Charles S. Kerfoot - Pasadena MD
Joseph J. Springer - Bel Air MD

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

H01F 706
H01F 2710

US Classification:

29606

Abstract:

An easy to assemble transformer for use in an electronics module of an electric vehicle. The transformer can be assembled from the "top down," thus alleviating the need to build the transformer as a subassembly unit. During manufacture of the transformer, windings are wound onto a thermally conductive coil form. Next upper and lower E-shaped core members are inserted into openings in the top and bottom of the form so that the side legs and the center legs of the E's touch and are in alignment. The thermally conductive coil form has a portion that touches a cold plate when the transformer is mounted on the cold plate. The transformer is further secured to the cold plate by a mounting bracket.
