POWER ADAPTER COMPONENTS, HOUSING AND METHODS OF ASSEMBLY

摘要

A dual-purpose transformer may be oriented in a plane perpendicular to planes in which printed circuit boards connected thereto are oriented, thereby providing structural support for a framework that can include a dense arrangement of internal power adapter components, in addition to stepping down voltage. Methods for ultrasonic welding are also provided and may be used to concurrently assemble, join and press-fit power adapter housing components. A ground lug is also provided that is shaped and located within a cover piece of a power adapter housing to allow for blind mating with a printed circuit board during an assembly process.

主权项

1. A power adapter comprising:
first and second printed circuit boards oriented in first and second planes, respectively, the first plane substantially parallel to the second plane; a transformer having first and second coiled windings extending between the first and second printed circuit boards, the first and second coiled windings oriented in a third plane substantially perpendicular to the first and second planes; and a body configured to enclose the first and second printed circuit boards and the transformer, the body having first and second faces oriented in planes substantially parallel to the first and second planes.
