Abstract
A releasable power assembly prevents damage to plugs and receptacles connected to refrigerated shipping containers (reefers). Reefers are temporarily stored in shipping port reefer scaffolds and then loaded onto or unloaded off of ground transportation or freighters. However, errors in port command and control systems may result in the failure to unplug reefers prior to loading or unloading. Conventional reefer power plugs and receptacles are twist-locked together and damaged or destroyed if not manually disconnected prior to reefer movement. An advantageous releasable power assembly automatically unlatches before reaching a breaking point for failure to disconnect plug and receptacle.
Claims7
A releasable power assembly comprising:
- a power plug having a plurality of conductive plug terminals;
- a power receptacle having a plurality of conductive receptacle terminals;
- the conductive plug terminals removably insert into the conductive receptacle terminals;
- the power plug removably locks to the power receptacle;
- a plug power cord extends from the plug;
- a receptacle power cord extends from the receptacle;
- the power plug cord reacts to a pulling force so as to unlock the power plug from the power receptacle;
- a loop trigger is fixedly attached to a first one of the ring latches and is removably attached to second one of the ring latches;
- the loop trigger unlocks the ring latches from the receptacle when the loop trigger is removed from the second one of the ring latches;
- and the plug power cord is looped around the loop trigger so as to remove the loop trigger from the second one of the ring latches when a pulling force is applied to the plug power cord.
