Abstract
Abstract A sealing grommet for sealing the wires extending from contacts, retained in a dielectric insert of an electrical connector assembly, to protect the contacts from moisture. The sealing grommet 19 has a plurality of axial passages 33 therethrough which communicate with axial bores 7 in the dielectric insert 3 which contains the contacts 5, and wires 27 pass through the passages 33. First sealing webs 37 and second sealing webs 39 extend inwardly from wall 35 towards the axis of the passages 33 and provide a moisture seal for contacts 5 contained within the insert 3 while providing for use of wires of varying diameters in a single grommet.
