The disclosure and prior art relates to power supply devices and more particularly pertains to a new power supply device for supplying AC voltage in a remote location.
An embodiment of the disclosure meets the needs presented above by generally comprising a housing that can slidably engage a power tool battery for retaining the housing on the power tool battery. A plurality of contacts is each coupled to and extends away from the housing. Each of the contacts is positioned at strategic locations corresponding to terminals on the power tool battery. A plurality of female electrical outlets is each recessed into the housing. Each of the female electrical outlets receives electrical current from the power tool battery supply voltage to an electronic device.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The housing 12 has a bottom wall 16 and a top wall 18, and a pair of rails 20 is each coupled to the bottom wall 16 of the housing 12. The rails 20 are spaced apart from each other and each of the rails 20 slidably engages a respective channel 22 in the power tool battery 14. Each of the rails 20 has a leg 24 and a foot 26. The leg 24 of each of the rails 20 extends away from the bottom wall 16 having the foot 26 on each of the rails 20 being directed toward each other. A stop 28 is coupled to the bottom wall 16 of the housing 12 and the stop 28 is oriented perpendicular to the rails 20. The stop 28 abuts the power tool battery 14 when the rails 20 slidably engage the respective channel 22 for inhibiting the housing 12 from sliding off of the power tool battery 14.
A plurality of contacts 30 is provided and each of the contacts 30 is coupled to and extends away from the bottom wall 16 of the housing 12. Each of the contacts 30 is positioned between the rails 20. Moreover, each of the contacts 30 is positioned at strategic locations corresponding to terminals 32 on the power tool battery 14. In this way each of the contacts 30 engages a respective one of the terminals 32 when the housing 12 is slid onto the power tool battery 14. Moreover, each of the contacts 30 is comprised of an electrically conductive material such that each of the contacts 30 is in electrical communication with the terminals 32 when the housing 12 is slid onto the power tool battery 14.
An inverter circuit 34 is positioned within the housing 12, and the inverter circuit 34 has an input 36 and an output 38. The input 36 is electrically coupled to the contacts 30 to convert DC voltage from the power tool battery 14 into AC voltage. A control circuit 40 is positioned within the housing 12 and the control circuit 40 is electrically coupled to the output 38 of the inverter circuit 34. The inverter circuit 34 may be a miniaturized, solid state inverter or the like.
A plurality of female electrical outlets 42 is each recessed into the housing 12. Each of the female electrical outlets 42 is in electrical communication with the contacts 30. Additionally, each of the female electrical outlets 42 receives electrical current from the power tool battery 14. In this way each of the female electrical outlets 42 can supply voltage to an electronic device 44. Moreover, each of the female electrical outlets 42 is electrically coupled to the control circuit 40 for delivering AC voltage. Each of the female electrical outlets 42 is positioned on the top wall 18 of the housing 12.
A plurality of power ports 46 is provided and each of the power ports 46 is recessed into the housing 12. Each of the power ports 46 is in electrical communication with the contacts 30. Thus, each of the power ports 46 receives electrical current from the power tool battery 14 for supplying voltage to a portable electronic device 48. Each of the power ports 46 is electrically coupled to the control circuit 40 and each of the power ports 46 is positioned on the top wall 18 of the housing 12. Each of the power ports 46 may comprise a usb port, a micro usb port or any other type of charge port.
A light emitter 50 is coupled to the housing 12 to emit light outwardly therefrom. The light emitter 50 is electrically coupled to the control circuit 40. Additionally, the light emitter 50 is turned on when the contacts 30 engage the terminals 32 on the power tool battery 14. In this way the light emitter 50 notifies a user that the female electrical outlets 42 and the power ports 46 are active. The light emitter 50 may comprise an LED or the like and the light emitter 50 may emit green colored light.
In use, the housing 12 is slid onto the power tool battery 14 thereby facilitating the contacts 30 to engage the terminals 32. Thus, the inverter circuit 34 converts the DC voltage of the power tool battery 14 into AC voltage. In this way each of the female outlets 42 can supply AC voltage to an electronic device 44, such as Christmas lights or the like. Moreover, the female electrical outlets 42 can supply AC voltage at a location where electrical service is not available. Additionally, each of the power ports 46 can be employed for charging portable electronic devices 48 such as smart phones or the like.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
