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.
