Method and apparatus of powering an electronic device using a removable power supply
View Patent ↗An electronic device lacking an internal power supply comprises electronic circuitry, an external power adapter having an input connector for receiving AC power from a conventional AC power outlet and for providing a low-voltage output signal to an output connector, and a first port electronically coupled to the electronic circuitry for receiving the low-voltage output signal from the output connector of the power adapter and for providing the low-voltage output signal to the electronic circuitry.
1. An electronic device, comprising:
a first housing in which is disposed a power adapter that converts an AC voltage signal to a DC low-voltage output signal, the power adapter comprising a prong connector that extends outwardly from the first housing for receiving the AC voltage signal from a conventional AC power outlet, and an output connector supported by the first housing for outputting the DC low-voltage output signal; and
a second housing in which is disposed electronic circuitry that is operable using the DC low-voltage output signal, wherein the second housing comprises a depression that is arranged to receive and releasably hold the first housing and wherein the electronic circuitry comprises an input connector that is positioned relative to the depression so as to cooperatively, electrically couple with the output connector when the first housing is received in its entirety within the depression.
2. The electronic device as recited in claim 1 , wherein the output connector and the input connector each comprise USB connectors.
3. The electronic device as recited in claim 1 , wherein the depression is sized and shaped such that only the prong connector extends from the second housing when the first housing is received in the second housing with the output connector being cooperatively, electrically coupled with the male input connector.
4. The electronic device as recited in claim 1 , further comprising a side wall adjacent to the input connector, wherein the side wall is angled to provide a gap between the first housing and the second housing when the first housing is received in the second housing with the output connector being cooperatively, electrically coupled with the male input connector.
5. An electronic device lacking a power supply, comprising:
a housing containing electronic circuitry that is operable using a DC low-voltage output signal, the housing comprising a depression that is arranged to receive and releasably hold a sealed power adapter that receives an AC voltage signal via use of a prong connector that extends outwardly from the sealed power adapter and which outputs the DC low-voltage output signal via an output connector, wherein the electronic circuitry comprises an input connector that is positioned relative to the depression so as to cooperatively, electrically couple with the output connector when the sealed power adapter is received in its entirety within the depression with only the prongs extending from the housing.
6. The electronic device as recited in claim 5 , wherein the input connector comprises a male USB connector which extends into the depression.
7. The electronic device as recited in claim 5 , further comprising a side wall adjacent to the input connector, wherein the side wall is angled to provide a gap between the housing and the sealed power adapter when the sealed power adapter is received in the second housing with the output connector being cooperatively, electrically coupled with the input connector.
