Low insertion force seating grommet assembly
View Patent ↗A low insertion force seating grommet assembly ( 10 a ) has a hollow body ( 12 ) arrayed along a longitudinal axis ( 14 ). The body ( 12 ) has a wide end ( 16 ) and a narrow end ( 18 ) connected by an intermediate portion ( 20 ). The narrow end ( 18 ) has a cylindrical aperture ( 18 a ) and the wide end ( 16 ) has a cup-shaped aperture ( 16 a ). A flange ( 22 ) surrounds the wide end ( 16 ) and is provided with a wall-opening engaging portion ( 24 ). Longitudinally extending relief grooves ( 26 ) are formed on the internal surface ( 28 ) of the cup-shaped aperture ( 18 a ). A cable ( 32 ) is frictionally engaged in the cylindrical aperture and penetrates the cup-shaped aperture. A cover ( 30 ) closes the cup-shaped aperture. The cable enters the cover along the longitudinal axis and exits the cover at an angle of 90 degrees relative to the longitudinal axis.
1. A low insertion force seating grommet assembly comprising:
a hollow body arrayed along a longitudinal axis, said body having a wide end and a narrow end connected by an intermediate portion, said narrow end having a cylindrical aperture and said wide end having a cup-shaped aperture;
a flange surrounding said wide end provided with a wall engaging portion;
a plurality of longitudinally extending relief grooves formed on the internal surface of said cup-shaped aperture;
a cable frictionally engaged in said cylindrical aperture and penetrating said cup-shaped aperture; and
a cover closing said cup-shaped aperture, said cable entering said cover along said longitudinal axis and exiting said cover at an angle of 90 degrees relative to said longitudinal axis.
2. The low insertion force seating grommet assembly of claim 1 wherein said cover has a circumferential disk engaging an outer surface of said flange and an internal cone engaging an inner surface of said cup-shaped aperture.
3. The low insertion force seating grommet assembly of claim 1 wherein said longitudinally extending relief grooves are V-shaped.
4. The low insertion force seating grommet assembly of claim 3 wherein there are 8 longitudinally extending relief grooves equally spaced about the circumference of said cup-shaped aperture.
5. The low insertion force seating grommet assembly of claim 4 wherein said intermediate portion is provided with at least one chamber having a diameter greater than the diameter of said cylindrical aperture.
