Abstract
Abstract An electrical power converter having an electrical transformer including a non-conductive bobbin carrying electrical windings, all of which is enclosed in a split housing forming top and bottom members, one of which members is an integrally formed latch disposed internally of the housing and adapted to fasten the top and bottom members together, and where the bobbin carries front and back structural extensions to make respective contact with the latch and the opposing rear wall of the housing and forming, with the bobbin, a compression brace to prevent unlocking movement of the latches after the top and bottom members have been mated together.
