10910076 Power-Cord-Cable 12V-Fridge-Freezers 12-Volt Refrigerator DC 12V, When designing the DC fridge cord & plug end, AR engineers included protection against reverse polarity and shorting/arcing of the terminals. The RB plug has a locating pin, which orientates the terminal polarity. To prevent shorting, the electrical connectors only come into contact once the orientation is correct and the pin is inserted into the recess.
