ABSTRACT:
A connector for optical fibre or electrical cables includes a grommet having a body of resilient silicone rubber having at least one bore extending therethrough. Two annular sealing webs extend from the wall of the bore. Each web extends both radially-inwardly and axially of the bore so as to be of generally conical configuration. The web is shaped so that its axial thickness is greater at its free edge than where it joins the wall of the bore and so that it defines a cylindrical sealing surface coaxial with the bore. The configuration and resilience of each web are such that the free edge of the web can sealingly engage a member of relatively small cross-section, for example, an electrical or optical fibre cable, but the web is deformable to permit the passage of a member of relatively large cross-section, for example, a contact or terminating member at the end of the cable, through the bore. Furthermore, the resilience and configuration of each web are such that the web can sealingly engage a cable passing through the bore even when the web is inverted so that it extends axially of the bore in the opposite direction relative to the body.
