POWER SUPPLY SYSTEM INCLUDING PANEL WITH SAFETY RELEASE

摘要

A power supply system for use with a power source. The system includes one or more power supply connections and an optional configuration with one or more remote control panels spaced from a safety circuit panel. The safety circuit panel includes a safety circuit. The system further includes a power cable with a safety ejector subsystem. The safety ejector subsystem includes a latch connected to the wall receptacle connector of the power cable and a tension line connected to the latch and to the power cable. When the power cable is placed in tension, such as when the power cable has not been disconnected from the wall receptacle in the ordinary way, the safety ejector subsystem forces the disconnection of the power cable from a plug, thereby ensuring that no live wiring is exposed to the environment.

主权项

1. A power supply system comprising:
a. a circuit panel arranged for connection to a power grid; b. one or more remote panels connected to the circuit panel, wherein each of the one or more remote panels includes a stop and a start button and c. one or more power cords for each remote panel, each power cord having a first end and a second end, wherein each first end is engaged with the power grid and each second end includes one or more pinhole faces with a plurality of pinholes, wherein the plurality of pinholes for each of the one or more power cords is configured for releasable engagement with a plurality of pins of a pin power plug, wherein each pin power plug is connectable to a device to be powered, wherein each of the one or more power cords is arranged to transfer power to the pin power plug only when the pins of the pin power plug and the pinholes of the power cord are aligned and engaged with one another, wherein a first portion of the plurality of pinholes of the power cord is arranged to supply current from the power grid to each of the one or more power cords when aligned and engaged with a first portion of the plurality of pins of the pin power plug, wherein a second portion of the plurality of pinholes of each of the one or more power cords is arranged to supply current from the corresponding power cord to the corresponding device when aligned and engaged with a second portion of the plurality of pins of the power plugs, wherein the circuit panel includes a safety circuit for each remote panel arranged to prevent current from the power grid to one or more of the power cords unless: 1) the first and second portions of the plurality of pinholes and the plurality of pins are aligned and engaged with one another; and 2) contacts of the safety circuit are moved from an open to an engaged position and the start button of the remote panel has been pushed, and wherein each power cord includes a safety ejection subsystem configured to cause disconnection of the second end of each power cord from the corresponding pin power plug when the two are connected together under tension loading of the connected power cord.
