This robust connector style provides mechanical support, correct orientation, and electromagnetic shielding for multi-wire cables. The D-shaped shell ensures the plug can only be inserted one way, protecting the delicate internal pins from damage. They are widely used in legacy serial ports, VGA video outputs, and industrial control interfaces.
