Abstract
A grommet (1) is provided for sealing an opening in a panel, through which at least one cable passes, comprising a tapered hollow body which sealingly engages the cable at least at a first end (10) and the edge of the opening via a groove (30) formed on a second end (20), wherein at least one means for reducing stiffness, in particular a recess (12, 14, 16) is provided on an inner surface (5) and/or on an outer surface (6) of the hollow body, so that elastic deformation of the grommet (1), in particular of its second end (2) is facilitated.

A grommet (1) for sealing an opening in a panel, through which at least one cable passes, said grommet (1) comprising a tapered hollow body having an inner surface (5), an outer surface (6), a first end (10) which sealingly engages the cable and a second end (20), a groove (30) formed in the outer surface (6) in proximity to the second end (20), said groove (30) being dimensioned such that portions of the outer surface (6) adjacent said groove (30) are engageable with portions of said panel adjacent said opening, wherein at least one stiffness reducing means for reducing stiffness and facilitating inward deformation of the second end (12, 14, 16) is provided on the hollow body, said stiffness reducing means (12, 13, 14) comprising at least one recess extending at least partly around said hollow body in proximity to said groove (30), said hollow body defining a thickness at said recess which is less than thicknesses of said hollow body at locations immediately adjacent said recess so that elastic deformation of the second end (20) of the grommet (1) is facilitated.
A grommet (1) for sealing an opening in a panel through which at least one cable may pass, said grommet comprising a tapering hollow body having an inner surface (5) and an outer surface (6), said hollow body further having a cross-sectionally small first end (10) dimensioned such that portions of said inner surface (5) adjacent said first end are sealingly engageable with said cable, said hollow body further having a cross-sectionally large second end (20), a groove (30) formed on portions of said outer surface (6) substantially adjacent said second end (20), said second end (20) and said groove (30) being dimensioned for sealing engagement with said panel adjacent said opening therein, said inner surface (5) of said hollow body being formed with at least one recess (12, 14, 16), said hollow body defining a thickness at said at least one recess which is less than thicknesses of said hollow body at locations immediately adjacent said recess for substantially reducing stiffness of said hollow body at said recess for facilitating deformation of hollow body during engagement of said grommet with said panel.
A grommet (1) for sealing an opening in a panel through which at least one cable may pass, said grommet comprising a tapering hollow body having an inner surface (5) and an outer surface (6), said hollow body further having a cross-sectionally small first end (10) dimensioned such that portions of said inner surface (5) adjacent said first end are sealingly engageable with said cable, said hollow body further having a cross-sectionally large second end (20), a groove (30) formed on portions of said outer surface (6) substantially adjacent said second end (20), said second end (20) and said groove (30) being dimensioned for sealing engagement with said panel adjacent said opening therein, said inner surface (5) of said hollow body being formed with at least one recess (12, 14, 16) for substantially reducing stiffness of said hollow body for facilitating engagement of said grommet with said panel, wherein said hollow body is unitarily formed from a material having a selected stiffness and wherein said grommet (1) further comprises a material (12') disposed in said at least one recess (12, 14, 16) and exhibiting a stiffness less than said hollow body.
