Abstract:
1. An industrial automation input output module comprising: an outer housing member comprising a top housing wall and an outer peripheral housing wall, said top housing wall and outer peripheral housing wall defining an open recess, said outer housing member further comprising an inner peripheral housing wall spaced from said outer peripheral housing wall, wherein a groove is defined between said inner peripheral housing wall and said outer peripheral housing wall; an inner housing member that is received in said open recess of said outer housing member so that said inner and outer housing members together define an interior space for containing at least one circuit board, said inner housing member comprising a projecting seal engagement wall that is received in said groove; a one-piece elastomeric main seal installed adjacent said groove, said main seal comprising: (i) a lateral seal portion that provides a fluid-tight seal between an inner face of said seal engagement wall and said inner peripheral housing wall; and, (ii) a face seal portion located in said groove that provides a fluid-tight seal between a tip of said seal engagement wall and said outer housing member; a connector mounting location comprising: (i) a connector opening defined in said top housing wall; (ii) an inner boss that projects from an inner side of said top housing wall and that surrounds said connector opening; and, (iii) an outer boss that projects from an outer side of said top housing wall and that surrounds said connector opening; a connector installed in said connector opening, said connector comprising: (i) an outer portion that is frictionally engaged with said outer boss to inhibit rotation of said connector relative to said outer boss; and, (ii) an inner portion including an elastomeric connector seal seated in a groove, said connector seal engaging both said connector inner portion and said inner boss to provide a fluid-tight seal between said connector inner portion and said inner boss.
