ABSTRACT:
A connector for a high amperage, AC or DC connection comprises a plug and a receptacle configured to a securely mate and lock with each other. Connector receptacles comprise a locking mechanism having a bottom latch bracket having two slots, a top latch bracket having arcuate grooves and being pivotally coupled to the bottom latch bracket, and a latching rod configured to engage a plug and having guide pins extending through the slots and arcuate grooves. When the top latch bracket is in an unlocked position, the distance between the guide pins is at a maximum. Upon turning the top latch bracket, the guide pins move cooperatively within the arcuate grooves and the distance between the guide pins is minimized and the latching rod securely engages the plug.
