D-Subminiature connectors are also called Type ‘D’ or ‘D-Sub’ connectors. The connector pair

plug and chassis receptacle each feature a D-shaped profile that interlock to ensure proper pin
orientation and connector seating.
Either chassis receptacle gender features two jack nuts for secure assembly of the cable plug to
the chassis receptacle.
Whether its gender is male or female, the cable plug features two jack screws for secure
connection to the jack nuts provided on the mating chassis receptacle. The jack screws may be
hand tightened or tightened with a standard flat-blade screwdriver.
