Direct coupling connector assembly

A male connector mountable to an electronic module having a printed circuit board, the male connector comprising:

• a male connector body including a male flange having a male bolting hole configured to couple with the electronic module and a male protrusion protruding from the male flange, the male protrusion includes an inner male protrusion protruding from the male flange and an outer male protrusion separate from the inner male protrusion and surrounding the inner male protrusion;
• a plurality of male taps penetrating the male connector body and connectable to the printed circuit board;
• a coupling bolt connected to the male connector body and rotatable in place, the inner male protrusion is separate from the coupling bolt;
• and
• a male O-ring surrounding the male protrusion and disposed in the male flange.

A direct coupling connector assembly, comprising:

• a male connector mountable to a first module provided with a first printed circuit board, the male connector including a male connector body having a male flange and a male protrusion protruding from the male flange, a plurality of male taps penetrating the male connector body and connectable to the first printed circuit board, a coupling bolt connected to the male connector and rotatable in place, and a male O-ring disposed in the male flange;
• and
• a female connector mountable to a second module provided with a second printed circuit board, the female connector including a female connector body having a female flange and a female protrusion protruding from the female flange, a plurality of female taps each including a pin extending through the female connector body and connectable to the second printed circuit board and a receptor connected to an end of the pin, an inner seal disposed in the female protrusion and configured to be in contact with at least a portion of the male connector, a coupling nut disposed in the female connector body, a female O-ring disposed in an outer wall of the female protrusion, and a support protruding from a center of the female flange and supporting the coupling nut, the female protrusion includes an inner female protrusion separate from the support, surrounding an outer side of the support, and protruding from the female flange, and an outer female protrusion separate from the inner female protrusion and surrounding the inner female protrusion.
