Power adapter with a single-piece insulator assembly

摘要

An AC-to-DC power adapter comprises a single-piece insulator unit. The various components of the power adapter such as a transformer, other circuitry, etc. are attached to the single-piece insulator unit. The single-piece insulator unit has embedded channels to provide electrical connectivity between the circuitry, The entire assembly is placed in housing and a cap assembly having prongs to connect to a AC wall outlet is ultrasonically welded to the housing.
