TRANSFORMER WITH A MOULDED INSULATIVE ENCAPSULATION

摘要

A compact high-voltage transformer resistant to moisture leaching and acids for airport navigation light systems includes primary and secondary windings wound upon a plastic coil form in turn surrounding a central portion of an iron transformer core. Connector socket members retained with prefixation on the coil form are provided with connector sleeves for receiving external leads, the sleeves being conductively connected to the ends of the primary and secondary windings. The transformer core is spaced from the inner surface of the coil form by means of spacer elements molded onto the inner surface of the coil form whereby a layer of thermoplastic synthetic resin material is injected between the core and the coil form during an injection molding operation. The injection molded jacket is the only insulation jacket provided in the transformer assembly.
