Grommets for holding cables
The present disclosure describes a grommet formed of a polymeric material and adapted for securing a cable within a cable hanger. The grommet includes a main body having a generally cylindrical profile, the main body further having a length, a thickness, and a longitudinal axis, a plurality of spokes extending radially inward from the main body at an oblique angle relative to the main body, and an annular inner wall coupled to the plurality of angled spokes and surrounding an interior cavity, wherein the annular inner wall extends the length of the main body. Other grommets and cable hanger assemblies are described herein.
1. A grommet, the grommet comprising:
a main body having a generally cylindrical profile and defining an outer diameter of the grommet;
an annular inner wall surrounding an interior cavity and defining an inner diameter of the grommet, the interior cavity being sized and configured to secure a cable therein;
a plurality of spokes extending between the main body and the annular wall, a first end of each of spoke is coupled to the main body and an opposing second end of each spoke is coupled to the annular wall, and each spoke extends at an oblique angle therebetween relative to the main body; and
at least two arms extending radially outwardly from the main body, at least one of the arms extending from a bottom edge of the main body and at least one of the arms extending from a top edge of the main body,
wherein the grommet is formed of a polymeric material and adapted for securing a cable within a cable hanger.
2. The grommet of claim 1 , comprising at least four arms extending radially outwardly from the main body, wherein at least two of the arms extend from the bottom edge of the main body and at least two of the arms extend from the top edge of the main body, wherein the at least two arms extending from the top edge of the main body are circumferentially staggered relative to the position of the at least two arms extending from the bottom edge of the main body.
3. The grommet of claim 2 , wherein the number of arms extending from the bottom edge of the main body is equal to the number of arms extending from the top edge of the main body.
4. The grommet of claim 1 , wherein the oblique angle that each spoke extends radially inward from the main body is in a range of from about 40 degrees to about 75 degrees.
5. The grommet of claim 1 , wherein an inner surface of the annular inner wall comprises a plurality of gripping features.
6. The grommet of claim 1 , wherein the main body has a first thickness and the annular inner wall has a second thickness, and wherein the first thickness is greater than the second thickness.
7. The grommet of claim 1 , further comprising a slot extending a length of the main body and annular inner wall.
8. The grommet of claim 1 , in combination with the cable, wherein the cable resides within the interior cavity of the main body.
9. The grommet of claim 1 , in combination with a cable hanger, wherein the cable hanger has opposable arms, and wherein the grommet is held between the opposable arms.
10. A grommet formed of a polymeric material and adapted for securing a cable within a cable hanger, the grommet comprising:
a main body having a generally cylindrical profile, the main body further having a length, a thickness, and a longitudinal axis;
a plurality of spokes extending radially inward from the main body;
an annular inner wall coupled to the plurality of spokes and surrounding an interior cavity, wherein the annular inner wall extends the length of the main body, and
at least four arms extending radially outwardly from the main body, at least two of the arms extending from a bottom edge of the main body and at least two of the arms extending from a top edge of the main body, wherein the at least two arms on the top edge of the main body are circumferentially staggered relative to the position of the at least two arms on the bottom edge of the main body.
11. The grommet of claim 10 , wherein each spoke is thinner at a center portion than at opposing ends.
12. The grommet of claim 10 , wherein each spoke has a serpentine or sawtooth profile.
13. A grommet formed of a polymeric material and adapted for securing a cable within a cable hanger, the grommet comprising:
a main body having a generally cylindrical profile with a top edge and a bottom edge, the main body further having a length, a thickness, and a longitudinal axis;
a plurality of spokes extending radially inward from the main body at an oblique angle relative to the main body;
an annular inner wall coupled to the plurality of angled spokes and surrounding an interior cavity, wherein the annular inner wall extends the length of the main body; and
a first annular flange extending radially outwardly from the top edge of the main body and a second annular flange extending radially outwardly from the bottom edge of the main body,
wherein the oblique angle that each spoke extends radially inward from the main body is in a range of from about 40 degrees to about 75 degrees.
14. The grommet of claim 13 , wherein an inner surface of the annular inner wall comprises a plurality of gripping features.
15. The grommet of claim 13 , wherein the main body has a first thickness and the annular inner wall has a second thickness, and wherein the first thickness is greater than the second thickness.
16. The grommet of claim 13 , further comprising a slot extending the length of the main body and annular inner wall.
17. The grommet of claim 13 , in combination with the cable, wherein the cable resides within the interior cavity of the main body.
18. The grommet of claim 13 , in combination with a cable hanger, wherein the cable hanger has opposable arms, and wherein the grommet is held between the opposable arms.
