Grommet for cable hanger
View Patent ↗A grommet adapted for insertion into a cable hanger includes a generally C-shaped main body formed of a polymeric material and having a longitudinal axis. Such a grommet can be securely held by a cable hanger.
1. A grommet adapted for insertion into a cable hanger, comprising:
a main body formed of a polymeric material, the main body having a generally C-shaped profile with an inner surface that defines a central cavity, the main body further having a length, a thickness and a longitudinal axis, the central cavity being centered in the main body; and
at least one rib projecting radially inwardly from the inner surface of the main body;
wherein the main body includes a plurality of apertures extending generally parallel to the longitudinal axis of the main body, each of the plurality of apertures having a closed perimeter in cross-section;
wherein each of the plurality of apertures is non-circular in cross-section and is positioned adjacent an inner diameter of the main body to reduce the effective hardness of the main body.
2. The grommet defined in claim 1 , wherein each of the plurality of apertures extends the full length of the main body.
3. The grommet defined in claim 1 , wherein at least some of the plurality of apertures extend less than the full length of the main body.
4. The grommet defined in claim 1 , further comprising upper and lower flanges that extend radially outwardly from the main body, and wherein at least one of the upper and lower flanges includes a protrusion that extends radially inwardly.
5. The grommet defined in claim 4 in combination with a cable hanger, wherein the main body of the grommet resides in a cavity formed by the cable hanger.
6. The grommet and cable hanger defined in claim 5 in combination with a cable captured by the inner surface of the main body of the grommet, wherein the cable is selected from the group consisting of fiber optic cables and hybrid fiber/power cables.
7. The grommet defined in claim 1 , wherein the at least one rib is a longitudinal rib.
8. The grommet defined in claim 1 , wherein the at least one rib is a circumferential rib.
9. An assembly, comprising:
(a) a grommet adapted for insertion into a cable hanger, comprising:
a main body formed of a polymeric material, the main body having a generally C-shaped profile with an inner surface that defines a central cavity, the main body further having a length, a thickness and a longitudinal axis, the central cavity being centered in the main body; and
at least one rib projecting radially inwardly from the inner surface of the main body;
wherein the main body includes a plurality of apertures extending generally parallel to the longitudinal axis of the main body, each of the plurality of apertures having a closed perimeter in cross-section;
wherein each of the plurality of apertures is positioned adjacent an inner diameter of the main body to reduce the effective hardness of the main body; and
(b) a generally U-shaped cable hanger, wherein the main body of the grommet resides in a cavity formed by the cable hanger.
10. The assembly defined in claim 9 , wherein each of the apertures is non-circular in cross-section.
11. The assembly defined in claim 9 , wherein each of the plurality of apertures extends the full length of the main body.
12. The assembly defined in claim 9 , wherein at least some of the plurality of apertures extend less than the full length of the main body.
13. The assembly defined in claim 9 , further comprising upper and lower flanges that extend radially outwardly from the main body, and wherein at least one of the upper and lower flanges includes a protrusion that extends radially inwardly.
14. The assembly defined in claim 9 , wherein the at least one rib is a longitudinal rib.
15. The assembly defined in claim 9 , wherein the at least one rib is a circumferential rib.
16. The assembly defined in claim 9 in combination with a cable captured by the inner surface of the main body of the grommet, wherein the cable is selected from the group consisting of fiber optic cables and hybrid fiber/power cables.
