Embodiment Construction

[0041]The present invention relates to compact power adapters. In one embodiment, a compact power adapter is facilitated by improved means of constructing and assembling the power adapter. According to one aspect, the connector can be used as a printed circuit board assembly that electrically couples the blades (or prongs) of the power adapter plug into the housing of the power adapter. The connector is used to couple the AC power to the printed circuit board assembly where the AC power is converted to DC power. The connector also facilitates assembly of the power adapter by providing a reliable interconnection without wires, soldering, or other conventional assembly operations. In one embodiment, the base of the power adapter plug of the power adapter may include a metal base that connects to the blades (or prongs) of the power adapter plug. The metal base can provide mechanical support to the blade and provide electrical connection to the internal terminals of the power ad...

Abstract

A compact power adapter, an electronic device, a power adapter and a method for assembling the power adapter are disclosed. In one embodiment, a compact power adapter is facilitated by improved approaches to construct and assemble the power adapter. According to one aspect, connectors can serve to electrically couple blades (or prongs) of a power adapter plug to a printed circuit board assembly internal to a housing for the power adapter. The connectors serve to couple AC power to the printed circuit board assembly where the AC power can be converted to DC power. The connectors also facilitate assembly of the power adapter in that reliable interconnections can be provided without wires, soldering or other custom assembly operations. In one embodiment, a base for a power adapter plug of a power adapter can include a metal base connected to a blade (or prong) of the power adapter plug. The metal base can provide mechanical support to the blade as well as electrical connectivity to an internal terminal for the power adapter plug. The internal terminals used by a power adapter plug of a power adapter can be coupled to a printed circuit board assembly using connectors, thereby facilitating interconnection with electrical components used by the power adapter.

Description

technical field [0001] The present invention relates to power adapters for electronic equipment. Background technique [0002] There are currently different portable electronic devices powered by rechargeable batteries. Examples of such portable electronic devices include mobile phones, portable media players, personal digital assistants (PDAs), and the like. To facilitate charging of rechargeable batteries, portable electronic devices are often sold with power adapters. Typically, a power adapter has a power plug for coupling to an AC outlet. The power plug is an important part of the power adapter that needs to meet certain specifications for safety reasons. The power adapter also includes an electronic circuit that converts AC power obtained from the AC outlet into DC power, and outputs the DC power via a cable with a connector. The connector of the cable connects to the portable electronic device and allows DC power to be received at the portable electronic device fo...
