ABSTRACT:
A header receptacle (10) which is protected against moisture and both conducted and radiated electromagnetic interferences. A flange (12) has a cured in place first sealant (20) disposed on the back side (14) of the flange wherein the first sealant (20) covers an opening in the center portion (16) of the flange (12). A metal shield (21) covers the first sealant (20) and is in electrical contact with the flange (12) by a conducting adhesive (18) which also adheres the metal shield (21) to the flange (12). An electromagnetic filter (26) is mounted adjacent to the metal shield (21). A plurality of spaced-apart male terminals (25) pass through the filter (26), the metal shield (21) and the first sealant (20). Each male terminal (25) is joined to the filter (26) to prevent exit/entry of electromagnetic interferences. A housing (30) is disposed on the center portion (16) on the front side (13) of the flange (12). The housing (30) contacts the first sealant (20) and forms a waterproof seal therebetween. The plurality of male terminals (25) extend forwardly into the housing (30). A second sealant (31) is bonded to the center portion (16) of the front side (13) of the flange (12). It is compressed between the peripheral edge (15) of the flange and the enclosure 11 further preventing passage of moisture. The header receptacle (10) is fastened to an enclosure (11).
