Abstract
A device for interfacing power from an electrical supply having power terminals, that permits implementation of a wide range of power cord lengths and voltage connection combinations. The device includes a body having a cord side and an appliance side. The body has four or more terminals located on the cord side of the body, with one terminal being a ground terminal. At least one electrical connecting device is adapted to connect terminals. In a first configuration, the device is used at a lower voltage. In a second configuration, the device is used at a higher voltage.
Claims22
A device for interfacing electrical power to an electrical appliance, the power being supplied through at least one lead wire and a ground wire, each lead and ground wire connected to a corresponding power terminal and the appliance having at least two appliance terminals for mating with the device, the device comprising:
- a body having a cord side and an appliance side;
- four or more cord terminals located on the cord side of the body, each cord terminal sized and adapted for receiving one of the power terminals;
- and
- at least one electrical connecting device, each electrical connecting device connecting a cord terminal to an appliance terminal or a cord terminal, so that, a first configuration allows for usage at a first voltage and a second configuration allows for usage at a second voltage,
- wherein the cord terminals are secured with the same appliance terminals in the first and second configurations.
A device for interfacing electrical power to an electrical appliance, the power being supplied through at least one lead wire and a ground wire, each lead and ground wire connected to a corresponding power terminal and the appliance having at least two appliance terminals for mating with the device, the device comprising:
- a body having a cord side and an appliance side;
- four or more cord terminals located on the cord side of the body, each cord terminal sized and adapted for receiving one of the power terminals wherein one cord terminal is a ground terminal;
- at least one sensing device connected to a respective cord terminal;
- and
- at least one electrical connecting device, each electrical connecting device connecting a cord terminal to an appliance terminal or a cord terminal, so that a first configuration allows for usage at a first voltage and a second configuration allows for usage at a second voltage,
- wherein the cord terminals are secured with the same appliance terminals in the first and second configurations.
