Abstract: A ruggedized electrical receptacle that has a shell configured to receive an interface of a mating connector and a contact subassembly received in the shell. The contact subassembly includes a contact printed circuit board, interface contacts coupled to one face of the contact printed circuit board, termination contacts coupled to the other face thereof, and an overmold overmolded on the board. The overmold surrounds the contact printed circuit board such that free ends of the interface contacts are exposed and tail ends of the termination contacts are exposed. An internal sealing member is disposed between an outer surface of the overmold and the inner surface of the shell, thereby creating a seal therebetween.

Abstract: A ruggedized electrical connector that includes a shell that has an interface front side and an opposite rear side for mounting on a printed circuit board. An interface sealing member is coupled to the interface front side of the shell. The interface sealing member substantially covers the interface front side of the shell for preventing contaminants from passing externally around the shell. A contact subassembly is received in the shell and includes a plurality of contacts and a housing supporting the contacts. Each of the contacts has an interface end and a tail end. The interface ends are arranged in a mating platform extending from the housing toward the front side of said shell for engaging a mating connector. An internal sealing member is coupled around the housing for preventing contaminants from passing internally though the shell. A rear shield is coupled to the rear side of the housing.
